When using articles, there are a number of ways to communicate specific shades of meanings with articles. Related rules for proper names don't make things easier. To complicate things even further, there are other determiners occasionally taking the place of articles. For instance, _some_ and _no_ function like articles, but behave somewhat differently with uncountable nouns.

Answer the questions to check if you understand the nuances!


Articles Advanced

Articles are ubiquitous; _the_ is the most common word in English, accounting for 7% of all words.

The concept of definiteness is hard to grasp even for advanced learners who don’t have articles in their first language. A spectacular example of such confusion is the occasion with Ivana Trump. She explained, “Yes, you know the outcome — ‘The Donald’ just slipped off the tongue, and now it seems to be making its ways to the political history books.”

### Verb Forms: Be/Have/Do and Regular/Irregular Verbs

#### **Explanation and Examples**

Verb forms are the different ways verbs change to show tense, voice, mood, or other grammatical features. In English, there are regular and irregular verbs.

-   Regular verbs: These verbs follow a consistent pattern when changing forms, usually by adding **-ed** for past simple and past participle forms.
-   Irregular verbs: These verbs have unique forms for past simple and past participle that do not follow the regular pattern.

The verbs "**be**," "**have**," and "**do**" are essential because they are used as auxiliary verbs and have irregular forms in the past tense.

#### **Regular and Irregular Verb Forms**

Regular verbs follow a pattern when forming their past simple and past participle forms, usually by adding **-ed**.

Example:

| Base Form | Past Simple | Past Participle |
| --------- | ----------- | --------------- |
| work      | worked      | worked          |

Irregular verbs have unique forms for past simple and past participle that do not follow the regular pattern.

Examples:

| Base Form | Past Simple | Past Participle |
| --------- | ----------- | --------------- |
| be        | was/were    | been            |
| have      | had         | had             |
| do        | did         | done            |

#### **Common Irregular Verbs**

Here is a table of some common irregular verbs with their past simple and past participle forms:

| Base Form | Past Simple | Past Participle |
| --------- | ----------- | --------------- |
| go        | went        | gone            |
| write     | wrote       | written         |
| sing      | sang        | sung            |
| swim      | swam        | swum            |
| bring     | brought     | brought         |
| buy       | bought      | bought          |
| catch     | caught      | caught          |
| come      | came        | come            |



Verb forms show tense, voice, mood, or other grammatical features, with regular and irregular verbs. Regular verbs follow a pattern by adding **-ed** for past simple and past participle forms. Irregular verbs have unique forms, including essential auxiliary verbs "be," "have," and "do." Examples of common irregular verbs are "go," "write," "sing," and "swim."

### Common Questions

In English, there are various types of questions that can be formed depending on the purpose and the information required. The following categories provide an overview of common questions and their subtypes.

#### **Simple present and simple past questions**

These questions are used to ask about habits, routines, or past events. They typically involve the simple present or simple past tense.

-   **Simple present questions:**

    -   Do they play basketball on weekends?
    -   How often do you visit your cousins?
    -   Does she own a car?
    -   What time does the concert start?

-   **Simple past questions:**
    -   Did they travel to Asia last year?
    -   What did you eat for lunch?
    -   What time did the conference end?

#### **"Why + negative" questions**

These questions are used to ask about the reasons for a negative situation or action.

-   Why isn't he attending the event?
-   Why don't you enjoy this movie?
-   Why can't I open this window?

#### **Questions with "Who" as the subject**

These questions seek information about the subject of a sentence, often involving the pronoun "who".

-   Who resides in that apartment?
-   What occurred during the meeting?
-   What's happening at the mall?
-   Who's got my umbrella?

#### **Questions with "who" as the object**

These questions ask about the object of a sentence, often involving the pronoun "who" as well.

-   Who did you encounter yesterday?
-   What did Laura mention about the assignment?
-   Who are you inviting to the party?
-   What was James wearing at the ceremony?

Basics. Common Questions.

### Conditionals and Wish

Conditionals are essential structures in English that help us talk about possibilities, hypothetical situations, and their consequences. They are often introduced with "if" and are divided into several types: zero, first, second, and third conditionals. For example, the first conditional ("If it rains, I will stay home.") expresses a real possibility in the future, while the second conditional ("If I won the lottery, I would travel the world.") is used for unlikely or imaginary situations.

The structure "wish" is used to express regrets about the present or past, or desires for things to be different. When talking about present situations we wish were different, we use "wish" with a past tense verb: "I wish I had more time." For past regrets, we use "wish" with the past perfect: "I wish I had studied harder." Both conditionals and "wish" help us communicate about real, unreal, and desired situations in nuanced ways.

In this challenge, you will answer 11 questions focused on recognizing and using conditionals and "wish" correctly. You'll need to identify the right structure, verb tense, and meaning in various scenarios.

### Adjectives and Adverbs

#### **Adjectives**

Adjectives are words that describe or modify nouns.

-   **Adjective + noun**: The adjective comes before the noun it modifies.

    -   Example: She has a _red_ car.

-   **Be/am/is/was + adjective**: The adjective follows a form of the verb "to be".

    -   Example: The weather is _warm_ today.

-   **Look/feel/smell/taste/sound + adjective**: The adjective follows a sensory verb.
    -   Example: The cake smells _delicious_.

#### **Adverbs**

Adverbs are words that modify verbs, adjectives, or other adverbs.

-   **Comparison with adjectives**: Adjectives modify nouns, while adverbs modify verbs, adjectives, and other adverbs.

    -   Example: She speaks _slowly_ (adverb). She is a _slow_ speaker (adjective).

-   **Words that are both adjectives and adverbs**: Some words, like "hard", "fast", "late", and "early", can function as both adjectives and adverbs.

    -   Example: He works _hard_ (adverb). He has a _hard_ job (adjective).

-   **Good and well**: "Good" is an adjective, while "well" is an adverb.
    -   Example: She is a _good_ student. She did _well_ on the test.

#### **Comparatives & Superlatives**

Comparatives and superlatives are used to compare differences between two or more things. Here's how they are formed for different types of adjectives:

| Type of Adjective          | Example   | Comparative    | Superlative    |
| -------------------------- | --------- | -------------- | -------------- |
| 1 syllable                 | tall      | taller         | tallest        |
| 2 syllable, ending with -y | happy     | happier        | happiest       |
| 2 or more syllables        | beautiful | more beautiful | most beautiful |

**Examples**:

-   John is _tall_, but Mark is _taller_. Peter is the _tallest_ of them all.
-   She was _happy_ yesterday, but today she is even _happier_. On her birthday, she was the _happiest_ I've ever seen her.
-   This painting is _beautiful_, but that one is _more beautiful_. The one in the gallery is the _most beautiful_ of all.

There are also some irregular comparatives and superlatives:

| Adjective | Comparative | Superlative |
| --------- | ----------- | ----------- |
| good      | better      | best        |
| bad       | worse       | worst       |
| far       | farther     | farthest    |

**Examples**:

-   Mary is a _good_ student, but Jane is _better_. Sarah is the _best_ student in the class.
-   His performance was _bad_, but her performance was even _worse_. The worst performance, however, was by the last contestant.
-   His house is _far_ from the city, but her house is even _farther_. Their cousin's house is the _farthest_ of all.

-   **Using more/less, most/least**: These words can be used to create comparative and superlative forms.

    -   Example: She is _more intelligent_ than her brother. He is the _least experienced_ worker.

-   **Modifiers with comparatives**: Phrases like "a little older" or "much older" can be used with comparatives.

    -   Example: She is _a little taller_ than her sister.

-   **Not as ... as ...**: This phrase can be used to show equality.

    -   Example: He is _not as tall as_ his brother.

-   **Superlatives with ever**: Phrases like "the best I've ever seen" can be used with superlatives.
    -   Example: This is the _best movie I've ever seen_.

#### **Enough**

"Enough" is used to indicate that something is sufficient.

-   **Enough + noun**: In this case, "enough" comes before the noun it modifies.

    -   Example: We have _enough_ food for the party.

-   **Enough without a noun**: "Enough" can be used on its own to indicate that something is sufficient.

    -   Example: "Do you want more cake?" "No, thanks. I've had _enough_."

-   **Adjective + enough**: In this case, "enough" comes after the adjective it modifies.
    -   Example: The water is _warm enough_ to swim in.

#### **Too**

"Too" is used to indicate that something is excessive or more than necessary.

-   **Too + adjective/adverb**: In this case, "too" comes before the adjective or adverb it modifies.

    -   Example: The coffee is _too hot_ to drink.

-   **Too much/many**: These phrases are used to indicate that something is excessive.

    -   Example: I ate _too much_ food at the party.

-   **Too vs not enough**: "Too" indicates excess, while "not enough" indicates insufficiency.
    -   Example: The soup is _too salty_, but the bread is _not salty enough_.

### Common uses of auxiliary verbs

#### **Common auxiliary verbs**

Auxiliary verbs are helping verbs that accompany the main verb to provide additional information about tense, mood, or voice. Some common auxiliary verbs include "be," "have," "do," "will," "can," "may," "might," "must," "shall," "should," and "could."

#### **Auxiliary verbs in negative forms**

Negative forms of auxiliary verbs like "should," "can," "have," and "must" are often used. Learn to form negative sentences using contractions (e.g., shouldn't, can't, haven't, mustn't) or the correct placement of "not" (e.g., should not, cannot, have not, must not).

Examples:

-   I can't swim.
-   They haven't finished their homework.
-   She mustn't tell anyone.

#### **Expressing interest or surprise using auxiliary verbs**

Use auxiliary verb phrases such as "you have?", "it is?", "he can't?", "you do?", "you did?" to express interest or surprise.

Examples:

-   A: I've just seen Bob.
    B: You have? This is interesting.
-   A: They're moving?
    B: They are? What a surprise!

#### **Tag questions**

Tag questions are added to the end of sentences to confirm or check information. Use affirmative tag questions with negative sentences and negative tag questions with affirmative sentences.

Examples:

-   You're coming to the party, aren't you?
-   She isn't studying English, is she?

#### **Using "too," "either," "so," and "neither" in sentences**

Learn to use "too" and "either" at the end of sentences, as well as "so" and "neither" in dialogues with various verbs (e.g., am, is, are, was, were, do, does, did, have, has, can, will, should).

Examples:

-   I like pizza, too.
-   She doesn't like coffee, either.
-   I am tired, and so is she.
-   He can't swim, and neither can I.

Remember that these examples and explanations are just a starting point.

### Conjunctions

Conjunctions are used to link words, phrases, or sentences together. They help make our speech and writing more coherent and organized. By using conjunctions, we can combine ideas and express more complex thoughts.

#### **Common Conjunctions**

There are several common conjunctions. Here are some examples:

1. **and**: used to connect similar ideas or items.

    - Example: I like apples and oranges.
    - Example: She sings and dances.

2. **but**: used to connect contrasting or opposing ideas.

    - Example: I wanted to go outside, but it was raining.
    - Example: He is smart, but he can be forgetful.

3. **or**: used to present alternatives or choices.
    - Example: Do you want tea or coffee?
    - Example: You can stay here or go home.

#### **What Conjunctions Can Join**

Conjunctions can join various language blocks, including:

1. **Words**: They can connect individual words.

    - Example: He has a cat and a dog.

2. **Phrases**: They can link phrases, such as noun phrases or verb phrases.

    - Example: She likes playing tennis but not watching it.

3. **Sentences**: They can also connect entire sentences.
    - Example: I wanted to go to the party, but I had to study for an exam.

#### **Complex and Compound Sentences Joined with Conjunctions**

Conjunctions play a crucial role in creating complex and compound sentences. Here's the difference between the two:

1. **Compound sentences**: These are formed by joining two independent clauses (complete sentences) using a coordinating conjunction like 'and,' 'but,' or 'or.'

    - Example: I wanted to watch a movie, but I had to finish my homework.

2. **Complex sentences**: These consist of an independent clause and one or more dependent clauses (incomplete sentences) connected by a subordinating conjunction, such as 'because,' 'since,' or 'although.'
    - Example: Although it was raining, we decided to go for a walk.

Conjunctions are essential tools that help you connect words, phrases, and sentences in English. Understanding how to use them will enable you to express more complex ideas and make your speaking and writing more engaging.

### Future Tenses: Future Simple, Future Continuous, and Future Perfect

#### **Future Simple**

The future simple tense is used to express an action or event that will happen in the future.

Example: She _will visit_ her grandparents tomorrow.

| Subject | Auxiliary (will/shall) | Base Form of Verb |
| ------- | ---------------------- | ----------------- |
| She     | will                   | visit             |

The future simple is used to describe an action or event in the future, unlike the present or past tenses, which describe actions or events in the present or past.

##### **Negative Sentences**

Add "not" after "will" or "shall" to form a negative sentence.

Example: She _will not visit_ her grandparents tomorrow.

##### **Questions**

Invert "will" or "shall" and the subject to form a question.

Example: _Will_ she _visit_ her grandparents tomorrow?

#### **Future Continuous**

The future continuous tense is used to describe an ongoing action or event that will be happening at a specific time in the future.

Example: She _will be visiting_ her grandparents at 5 PM tomorrow.

| Subject | Auxiliary (will be/shall be) | Present Participle (-ing form) |
| ------- | ---------------------------- | ------------------------------ |
| She     | will be                      | visiting                       |

The future continuous emphasizes the ongoing nature of an action in the future, unlike the future simple, which focuses on the occurrence of the action.

##### **Negative Sentences**

Add "not" after "will be" or "shall be" to form a negative sentence.

Example: She _will not be visiting_ her grandparents at 5 PM tomorrow.

##### **Questions**

Invert "will be" or "shall be" and the subject to form a question.

Example: _Will_ she _be visiting_ her grandparents at 5 PM tomorrow?

#### **Future Perfect**

The future perfect tense is used to express an action or event that will be completed by a specific time in the future.

Example: She _will have visited_ her grandparents by the end of the week.

| Subject | Auxiliary (will have/shall have) | Past Participle |
| ------- | -------------------------------- | --------------- |
| She     | will have                        | visited         |

The future perfect emphasizes the completion of an action by a specific time in the future, unlike the future simple or future continuous, which focus on the occurrence or ongoing nature of the action.

##### **Negative Sentences**

Add "not" after "will have" or "shall have" to form a negative sentence.

Example: She _will not have visited_ her grandparents by the end of the week.

##### **Questions**

These tenses are formed using different auxiliary verbs: "will/shall" for future simple, "will be/shall be" for future continuous, and "will have/shall have" for future perfect. Negative sentences and questions involve placing "not" after the auxiliary or inverting the auxiliary and subject, respectively.

Basics. Some Uses of Go, Get, Do & Make, and Have.

### Past Simple (I did)

#### **Explanation and Examples**

The Past Simple tense is used to describe actions or events that happened in the past and are now completed. These actions or events can be specific or general, with a definite beginning and end.

Examples:

-   I _worked_ at a bookstore last year.
-   She _visited_ Paris two months ago.

#### **Formation**

To form the Past Simple tense, we use the past form of the main verb. For regular verbs, we add _-ed_ to the base form. For example:

| Base Form | Past Simple |
| --------- | ----------- |
| work      | worked      |
| study     | studied     |

However, some verbs are [irregular](/tags/irregular-verb) and have a different past form. For example:

| Base Form | Past Simple |
| --------- | ----------- |
| go        | went        |
| be        | was / were  |

Past Simple is different from Present Simple, which describes habits or facts in the present. It also differs from Past Continuous, which describes ongoing actions in the past.

#### **Negative Sentences**

To form negative sentences in Past Simple, we use _did not_ (or _didn't_) followed by the base form of the verb.

| Past Simple | Negative Past Simple |
| ----------- | -------------------- |
| worked      | didn't work          |
| visited     | didn't visit         |

#### **Questions**

To form questions in Past Simple, we use _did_ followed by the subject and the base form of the verb.

| Past Simple | Question Past Simple |
| ----------- | -------------------- |
| worked      | Did you work?        |
| visited     | Did she visit?       |

### Past Continuous (I was doing)

#### **Explanation and Examples**

The Past Continuous tense is used to describe actions or events that were ongoing or in progress at a specific time in the past. This tense emphasizes the duration or continuity of the action.

Examples:

-   I _was working_ at a bookstore when you called.
-   She _was visiting_ Paris when it started raining.

#### **Formation**

To form the Past Continuous tense, we use the past form of the verb _to be_ (was/were) followed by the _-ing_ form of the main verb.

Examples:

| Subject | Past Continuous |
| ------- | --------------- |
| I       | was working     |
| They    | were studying   |

Past Continuous is different from Past Simple, which describes completed actions in the past. It also differs from Present Continuous, which describes ongoing actions in the present.

#### **Negative Sentences**

To form negative sentences in Past Continuous, we add _not_ after the past form of the verb _to be_ (was/were).

| Past Continuous | Negative Past Continuous |
| --------------- | ------------------------ |
| was working     | wasn't working           |
| were studying   | weren't studying         |

#### **Questions**

To form questions in Past Continuous, we invert the subject and the past form of the verb _to be_ (was/were), followed by the _-ing_ form of the main verb.

| Past Continuous | Question Past Continuous |
| --------------- | ------------------------ |
| was working     | Was I working?           |
| were studying   | Were they studying?      |



The **Past Simple** tense describes completed actions in the past, using regular (-ed) or irregular verb forms. The **Past Continuous** tense expresses ongoing actions in the past, using "was/were" and the -ing form of the main verb. Negative sentences use "didn't" or "not" with the verb, while questions involve inverting the subject and auxiliary verb.

### Phrasal Verbs

Phrasal verbs are combinations of a verb and a preposition or an adverb, which together create a new meaning. The position of the preposition or adverb can vary, sometimes coming directly after the verb or following the object of the verb. In some cases, the preposition or adverb can be placed between the verb and its object, or after the object. These expressions often have a different meaning than the individual words, making them unique and sometimes challenging to learn.

#### **Phrasal Verbs Without an Object**

These phrasal verbs do not require an object to complete their meaning.

Examples:

-   The dog ran away from home.
-   He got up early in the morning.
-   Keep on practicing, and you'll get better.

#### **Phrasal Verbs With an Object**

These phrasal verbs require an object to complete their meaning.

Examples:

-   She put on her shoes before leaving the house.
-   He turned off the lights before going to bed.
-   I need to fill out this form for the application.

**Phrasal verbs** are combinations of a verb with a preposition or an adverb, creating new meanings. The position of the preposition or adverb can vary in a sentence. They can be categorized into two groups: those without an object, like "ran away" or "got up," and those with an object, such as "put on" or "turned off." Understanding phrasal verbs is crucial for effective communication in English.

### Pronouns and Possessives

Pronouns are words that replace nouns in a sentence to avoid repetition, and possessives indicate ownership or a relationship between two entities. Understanding pronouns and possessives is crucial for clear and concise communication in English.

#### **Pronouns**

Pronouns can represent people or things. The table below shows subject and object forms of personal pronouns along with examples:

| Subject | Object | Example                       |
| ------- | ------ | ----------------------------- |
| I       | me     | I see him. / He sees me.      |
| we      | us     | We know her. / She knows us.  |
| you     | you    | You found it. / It found you. |
| he      | him    | He has it. / It has him.      |
| she     | her    | She wants it. / It wants her. |
| they    | them   | They are here. / We see them. |
| it      | it     | It is here. / We see it.      |

#### **Possessives**

Possessives show ownership or a relationship between two entities. The table below presents possessive forms of pronouns and nouns along with examples:

| Possessive Pronoun | Possessive Noun | Example                          |
| ------------------ | --------------- | -------------------------------- |
| my                 | 's              | my book / John's book            |
| our                | 's              | our house / Sarah's house        |
| your               | 's              | your car / Tom's car             |
| his                | 's              | his dog / Peter's dog            |
| her                | 's              | her cat / Emily's cat            |
| their              | 's              | their toys / The children's toys |
| its                | 's              | its tail / The dog's tail        |

To form questions with possessives, use "whose": _Whose book is this?_

"Short forms" like mine, yours, and theirs are formed by adding the appropriate possessive pronoun to the noun: _This book is mine (my book)._

#### **Reflexive Pronouns**

Reflexive pronouns like myself, yourself, and themselves refer back to the subject of the sentence:

| Subject | Reflexive Pronoun                        | Example                                                   |
| ------- | ---------------------------------------- | --------------------------------------------------------- |
| I       | myself                                   | I did it myself.                                          |
| we      | ourselves                                | We can do it ourselves.                                   |
| you     | yourself (singular), yourselves (plural) | You should treat yourself. / You should treat yourselves. |
| he      | himself                                  | He hurt himself.                                          |
| she     | herself                                  | She prepared herself for the exam.                        |
| they    | themselves                               | They enjoyed themselves at the party.                     |
| it      | itself                                   | The cat cleaned itself.                                   |

Reflexive pronouns emphasize the subject's involvement in the action or indicate that the subject and object are the same entity.

### Reported Speech

Reported speech, also known as indirect speech, is a way to express what someone else has said without directly quoting their exact words. It is commonly used to relay information or recount events in a more natural and conversational manner.

To form reported speech, we usually change the tense of the original statement, and we replace the original speaker's pronouns with the appropriate third-person pronouns. Additionally, we may need to adjust time expressions and other contextual details.

For example, consider the following direct speech:

> He said, "I **am** studying English."

When we convert it to reported speech, we get:

> He said (that) he **was** studying English.

Here's a simple table to illustrate some of the main tense changes:

| Direct Speech      | Reported Speech |
| ------------------ | --------------- |
| Present Simple     | Past Simple     |
| Present Continuous | Past Continuous |
| Present Perfect    | Past Perfect    |
| Past Simple        | Past Perfect    |

Remember that the reported speech should convey the meaning of the original statement accurately, even if some of the words or tenses are changed. Practice with various examples to get a better understanding of how to form and use reported speech correctly.

Here are four more examples of reported speech:

1. Direct speech: She says, "We **are** going to the cinema tonight."
   Reported speech: She says (that) they **are** going to the cinema tonight.

2. Direct speech: They told us, "We **have** finished our project."
   Reported speech: They told us (that) they **had** finished their project.

3. Direct speech: He said to her, "I **will** call you later."
   Reported speech: He **told** her (that) he **would** call her later.

4. Direct speech: She said, "They **were** waiting for the bus."
   Reported speech: She said (that) they **had been** waiting for the bus.
   

**Reported speech**, or **indirect speech**, is used to convey what someone else said without directly quoting their exact words. It often involves changing tenses, pronouns, and contextual details to create a more natural and conversational narrative. Mastering reported speech requires understanding the main tense changes and practicing with various examples to ensure the original meaning is accurately conveyed.

### There is/are and It

In English, impersonal sentences are often constructed using the pronoun "it" or the phrase "there is/are". Impersonal sentences are sentences in which the subject is not a specific person or thing, but rather an idea or a general concept. Impersonal sentences are often used to make general statements, give advice, or describe situations in a neutral and objective way.

#### **There is/are**

"There is/are" can be used to express different things. Some of them are listed below.

-   To show the presence of something: _there are_ books on the shelf.
-   To express an event happening at a specific time: _there is_ a party tonight.
-   To mention the number of parts in a whole: _there are_ four chapters in the book.
-   For abstract items or situations: _there is_ nothing on TV.
-   With uncountable nouns: _there is_ milk in the fridge.
-   To express a quantity: _there are a lot_ of people in the park.

Questions with _there is/are_ are formed like this: _is there_ a restaurant nearby? _Are there_ any apples left?

The negatives are formed as follows: _there isn't_ any sugar. _There aren't_ any tickets available.

"There is/are" can be used with verb tenses other than present. See the examples below.

-   Use _There was/were_ for past events: _there was_ an accident yesterday. _There were_ ten people at the meeting.
-   Use _There has/have been_ for past events with present relevance: _there has been_ a change in plans. _There have been_ many complaints.
-   Use _There will be_ for future events: _there will be_ a meeting tomorrow.

#### **It**

Here are some common uses of "it" to form impersonal sentences.

-   For time and day: _it's_ 3 o'clock. _It's_ Friday.
-   For distance: _it's_ 5 miles to the nearest town.
-   For weather: _it's_ raining. _It's_ hot today.

It's important to notice that there are other uses.

### Word Order

Word order is the arrangement of words in a sentence to convey meaning and provide structure. In English, word order generally follows a subject-verb-object (SVO) pattern, but other elements such as adjectives, adverbs, and prepositional phrases can affect the arrangement. Understanding the basic word order in English can help you create clear and coherent sentences.

#### **Basic English Word Order: Subject-Verb-Object (SVO)**

In English, the basic word order is Subject-Verb-Object (SVO). The subject comes first, followed by the verb, and finally the object: **She (subject) reads (verb) a book (object).**

#### **Adjectives and Adverbs**

Adjectives typically come before the noun they modify, while adverbs can be placed in different positions depending on what they modify.

-   Example (adjective): _She reads an interesting book._
-   Example (adverb of manner): _She reads quickly._
-   Example (adverb of frequency): _She often reads._

##### **Adverb Placement**

Adverbs can modify verbs, adjectives, or other adverbs. Their placement in a sentence depends on what they modify.

-   If the adverb modifies a verb, it usually comes after the verb: _She reads quickly._
-   If the adverb modifies an adjective, it comes before the adjective: _She reads a very interesting book._
-   If the adverb modifies another adverb, it comes before that adverb: _She reads quite quickly._

##### **Still, Yet, Already, and Similar**

These adverbs are used to express the progress or completion of an action.

-   "Still" typically comes before the main verb.
    -   Example: _She is still reading the book._
-   "Yet" usually comes at the end of the sentence in questions and negative statements.
    -   Example: _Has she finished the book yet?_ or _She hasn't finished the book yet._
-   "Already" is placed before the main verb or at the end of the sentence.
    -   Examples: _She has already read the book_ or _She has read the book already._

#### **Prepositional Phrases**

Prepositional phrases provide additional information about time, place, or manner and usually come after the main subject-verb-object structure.

-   Example (place): _She reads a book in the library._
-   Example (time): _She reads a book before dinner._
-   Example (manner): _She reads a book with enthusiasm._

#### **Questions**

In questions, the word order changes to place the auxiliary verb before the subject.

-   Example: _Does she read a book?_ (Auxiliary verb "does" comes before the subject "she")

#### **Negation**

To form negative sentences, place the word "not" after the auxiliary verb.

-   Example: _She does not read a book._

Understanding these basic principles of word order will help you create clear and coherent sentences in English.
So, this is the theory. Now try the challenge!

### Present Perfect (I have done)

#### **Explanation and Examples**

The Present Perfect tense is used to describe actions or events that started in the past and have a connection to the present. This tense often indicates that the action has been completed, but its result or effect is still relevant.

Examples:

-   I _have finished_ my homework.
-   She _has traveled_ to Europe several times.

#### **Formation**

To form the Present Perfect tense, we use the auxiliary verb _have_ (or _has_ for third person singular) followed by the past participle of the main verb. For regular verbs, the past participle is the same as the past simple form, usually ending in _-ed_. Irregular verbs have different past participle forms.

Examples:

| Subject | Base Form | Present Perfect |
| ------- | --------- | --------------- |
| I       | work      | have worked     |
| He      | study     | has studied     |
| We      | go        | have gone       |
| She     | be        | has been        |

Present Perfect is different from Past Simple, which describes completed actions in the past with no connection to the present. It also differs from Present Simple, which describes habits or facts in the present.

To identify the Present Perfect tense, look for the auxiliary verb _have_ or _has_ followed by the past participle of the main verb.

#### **Negative Form**

To form negative sentences in Present Perfect, we add _not_ after the auxiliary verb _have_ or _has_.

Examples:

| Present Perfect | Negative Present Perfect |
| --------------- | ------------------------ |
| have finished   | haven't finished         |
| has traveled    | hasn't traveled          |

#### **Questions**

To form questions in Present Perfect, we invert the auxiliary verb _have_ or _has_ and the subject, followed by the past participle of the main verb.

Examples:

| Present Perfect | Question Present Perfect |
| --------------- | ------------------------ |
| have finished   | Have you finished?       |
| has traveled    | Has she traveled?        |



Any idea what **Present Perfect** is? The **Present Perfect** tense describes actions with a connection to the present, formed using "have" or "has" and the past participle of the main verb. It differs from **Past Simple** and **Present Simple** tenses. To identify Present Perfect, look for "have" or "has" followed by a past participle. Negative sentences add "not" after the auxiliary verb, and questions invert the subject and auxiliary verb.

### Advanced Conditionals and Wish

This challenge focuses on advanced uses of conditionals and the structure "wish" in English grammar. Conditionals are sentences that describe possible situations and their outcomes, often using "if." Beyond basic forms, advanced conditionals include mixed conditionals (combining different time frames) and nuanced usage of "if only" and "wish" for expressing regrets, hypothetical desires, or unreal situations.

For example, a mixed conditional might be: "If I had studied medicine, I would be a doctor now" (past condition, present result). The structure "wish" is used to express unreal or regretted situations, such as "I wish I had known about the meeting" (regret about the past) or "I wish it would stop raining" (desire for a change in the present/future). Mastering these forms is essential for expressing complex ideas and emotions in English.

Understanding the subtle differences between various conditional forms and wish statements will help you sound more fluent and precise. This quiz will test your ability to identify, correct, and construct sentences using advanced conditionals and "wish" appropriately.

### Passive Voice

#### **Explanation and Examples**

The passive voice is used to emphasize the action or the receiver of the action, rather than the person or thing performing the action. The subject of the sentence is the receiver of the action.

Examples:

-   Active: John _wrote_ the letter.
-   Passive: The letter _was written_ by John.
-   Active: They _have been painting_ the house.
-   Passive: The house _has been painted_ by them.

#### **Formation**

The passive voice is formed by using the appropriate form of the verb _to be_ for the tense, followed by the past participle of the main verb.

Example for Present Continuous:

-   Active: They _are painting_ the house.
-   Passive: The house _is being painted_ by them.

Example for Present Perfect:

-   Active: They _have painted_ the house.
-   Passive: The house _has been painted_ by them.

#### **Passive Voice in Different Tenses**

| Tense              | Example (Active)               | Example (Passive)              |
| ------------------ | ------------------------------ | ------------------------------ |
| Present simple     | They _make_ the toys           | The toys _are made_            |
| Present continuous | They _are making_ the toys     | The toys _are being made_      |
| Present perfect    | They _have made_ the toys      | The toys _have been made_      |
| Past simple        | They _made_ the toys           | The toys _were made_           |
| Past continuous    | They _were making_ the toys    | The toys _were being made_     |
| Past perfect       | They _had made_ the toys       | The toys _had been made_       |
| Future simple      | They _will make_ the toys      | The toys _will be made_        |
| Future continuous  | They _will be making_ the toys | The toys _will be being made_  |
| Future perfect     | They _will have made_ the toys | The toys _will have been made_ |

To identify the passive voice, look for the appropriate form of the verb _to be_ for the tense, followed by the past participle of the main verb.

#### **Negative Sentences**

To form negative sentences in the passive voice, add _not_ after the appropriate form of the verb _to be_ for the tense.

Examples:

-   The toys _are not made_ (Present simple)
-   The toys _are not being made_ (Present continuous)
-   The toys _have not been made_ (Present perfect)

#### **Questions**

To form questions in the passive voice, invert the subject and the appropriate form of the verb _to be_ for the tense, followed by the past participle of the main verb.

Examples:

-   _Are_ the toys _made_? (Present simple)
-   _Are_ the toys _being made_? (Present continuous)
-   _Have_ the toys _been made_? (Present perfect)
    

The **Passive Voice** emphasizes the action or receiver, using the verb to be and the past participle of the main verb. It can be formed in different tenses, including continuous and perfect. Negative sentences add not after the verb to be, while questions invert the subject and the verb to be.

Collocations (Upper Intermediate, B2), Part 1.

Very often when we compare different objects or events. As we tend to be as colorful as possible, using only comparative or superlative form of adjectives is not always enough.

Because of this, we begin to add adverbs or special constructions such as far, by far, much, a lot, a little etc.

The knowledge of the rules how to use the intensifiers of comparison usually indicates an advanced student.


Comparatives and Superlatives

There are five types of subordinate clauses in English: the subject, the predicative, the attributive, the object and several types of adverbial clauses.

Adverbials happen to be the thing this challenge is about.


Complex Sentence: Adverbials

There are five types of subordinate clauses in English: the subject, the predicative, the attributive, the object and several types of adverbial clauses.

In English grammar, all the clauses are subdivided into three main groups: noun clauses, adjective clauses and adverb clauses.

The Noun clauses include three types of subordinate sentences such as the subject clause, the predicative clause and the object clause. Usually in subordinate clauses we use the direct word order but in some cases we may face a particular version of inversion. Also, different subordinate clauses need to be introduced by different introductory words which cannot be omitted.

Try the challenge to figure out what all this is about!


Complex Sentence

Subjunctive mood is represented by three main forms in contemporary English: present subjunctive, past subjunctive, past perfect subjunctive. Other forms such as present continuous subjunctive and past continuous subjunctive are used very rarely.

These subordinate clauses may be divided into 4 types according to the realness of the condition and the time.

Apart from the aforementioned, advanced students are particularly interested in the accurate usage of such verbs as _should_, _would_, _could_, _might_, _wish_ after _if_ and in the case when it is omitted in the mixed type conditionals.

All this is simple and clear for you, and you would easily prove it passing a test on the subject, wouldn't you?


Conditional Subjunctive

Scores above 7 effectively cannot be reached without deep understanding of IELTS exam format.
This challenge covers how IELTS is structured. Use it to make sure you understand what you will encounter during the examination and detect possible problem areas.


IELTS Test Format

There are some verbs in English that need different type of objects: either gerunds or infinitives. In order not to make a mistake students usually learn these verbs by heart. Besides, there are also such verbs that may be followed by both gerunds and infinitives, and the choice of the object type directly influences the meaning of a sentence.

Of course there are not so many verbs such as “forget” in English, but the reason for the choice of the infinitive or the gerund object each time will be different and will strongly influence the meaning of a sentence. And it’s a real challenge for advanced students.

Speaking about the challenge, did you forget... ehm... nervermind...


Gerund vs Infinitive

Inversion is the change of a standard word order from subject-verb to verb-subject. If there is more than one verb, only the first auxiliary verb swaps places with the subject. Inversion is usually used in questions, but there are a number of other scenarios in which it applies. It is often used to make the speech more emphatic.

Inversion is not used a lot in everyday colloquial speech, it sounds a bit bookish and will remind people of Shakespeare’s times.

Hardly it makes knowledge of the rules of inversion less important for advanced students, does it?


Inversion

Complex participles and gerunds, their perfect, passive or perfect-passive forms are interesting. The accurate understanding and usage of such participial nad gerund constructions especially after the verb _to be_ and different prepositions; before nouns; and also in set expressions and constructions shows... shows...

Actually, go and try to figure it out yourself.


Participle vs Gerund

Understanding the principle of the sequence of tenses in direct and indirect speech must not be a great challenge!

However, the devil is in the details, exceptions and rules variations, not to mention indirect sentences with modal verbs and the usage of adverbs of time and place, which in turn must be changed in a special way.


Sequence of Tenses in Indirect Speech

In English there are some verb constructions having special indirect meaning, such as _used to_, _would_, _get used to_, _get doing_, _be to do_, _happen to do_, _be going to do something_, _be about to do something_ etc.

For example “I would go swimming to the swimming pool in my childhood” – means that in the past I went to swim periodically but now I don’t go swimming anymore...

These constructions help to add different shades to the main meaning of a sentence without wordy explanations.
Now, how about getting answering the questions?

That Challenge

All English [verbs](/tags/verb) are divided into three big groups of **transitive**, **intransitive** and **linking verbs**. The belonging to one of these groups influences the choice of the object the verb may be followed by: direct, indirect, indirect without a preposition, prepositional object or the complex object. Another reason to know about "transitivity/intransitivity" of a verb is to be able to use the verb in the [passive voice](/tags/verb-passive-voice). In addition, some verbs such as _get_, _grow_, _keep_, _look_, and alike, can be also link verbs that will strongly influence the meaning of a sentence.


Transitive and Intransitive Verbs

We use this expression to talk about habits or repeated actions in the past which we don't do in the present.
