Articles: A, An, The & Zero Article

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.”

Say vs. Tell, Advice, and Promises: Communication Collocations

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?

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?

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.
