The correct answers are We are having the spooky attic cleaned right now. and We have had the creepy basement windows replaced.
The causative structure (have + object + past participle) can be used in any tense.
"Are having... cleaned" is the present continuous, and "have had... replaced" is the present perfect.
"Having the walls painting" is incorrect because it uses an -ing verb instead of a past participle ("painted").
"Have had replaced the creepy basement windows" is incorrect because the object must come before the past participle.
Verb
A verb is a word that expresses an action, a state, or an occurrence — and it's the engine of every English sentence. Understanding how verbs work is foundational to everything else in English grammar, from forming questions to building complex sentences.
Verb Forms
Most English verbs have five inflected forms:
- Base form (go, write, climb) — used as an infinitive, imperative, present subjunctive, and present indicative in all persons except third-person singular.
- -s form (goes, writes, climbs) — used for the present tense, third-person singular (she writes).
- Past tense (went, wrote, climbed) — also called the preterite.
- Past participle (gone, written, climbed) — identical to the past tense for regular verbs, but often different for irregular verbs.
- -ing form (going, writing, climbing) — serves as the present participle and gerund.
The verb be is a special case with more forms than any other English verb (am, is, are, was, were, been, being). Modal verbs like can, must, and should have fewer forms than typical verbs.
Main Verbs and Auxiliaries
Verbs in English often appear in combinations: one or more auxiliary verbs paired with a main verb.
- The dog was barking very loudly.
- My hat has been cleaned.
- Jane does not really like us.
The first verb in the combination is the finite verb (it carries tense and agrees with the subject). The rest are nonfinite (infinitives or participles). Notice that these verbs don't always sit next to each other — as in does not really like.
Tense, Aspect, and Mood
English expresses tense (time reference), aspect (how an action unfolds over time), and mood (the speaker's attitude toward the action) mostly through verb combinations rather than word endings. That's why you'll encounter labels like "present progressive" or "conditional perfect" — these are specific tense–aspect–mood combinations built with auxiliaries.
Self-check: If you can change the time of a sentence by swapping one word (She runs → She ran), that word is the verb.

Present
Present tense is used, in principle, to refer to circumstances that exist at the present time (or over a period that includes the present time) and general truths. However the same forms are quite often also used to refer to future circumstances, as in "He's coming tomorrow" (hence this tense is sometimes referred to as present-future or nonpast). For certain grammatical contexts where the present tense is the standard way to refer to the future, e.g., conditional sentences and dependent clauses. It is also possible for the present tense to be used when referring to no particular real time (as when telling a story), or when recounting past events (the historical present, particularly common in headline language). The present perfect intrinsically refers to past events, although it can be considered to denote primarily the resulting present situation rather than the events themselves.
The present tense has two moods, indicative and subjunctive; when no mood is specified, it is often the indicative that is meant. In a present indicative construction, the finite verb appears in its base form, or in its -s form if its subject is third-person singular. (The verb be has the forms am, is, are, while the modal verbs do not add -s for third-person singular.)
Past
Past tense forms express circumstances existing at some time in the past, although they also have certain uses in referring to hypothetical situations (as in some conditional sentences, dependent clauses and expressions of wish). They are formed using the finite verb in its preterite (simple past) form.
Certain uses of the past tense may be referred to as subjunctives; however the only distinction in verb conjugation between the past indicative and past subjunctive is the possible use of were in the subjunctive in place of was.
Note also that in certain contexts past events are reported using the present perfect.
Future
English is sometimes described as having a future tense, although since future time is not specifically expressed by verb inflection, some grammarians identify only two tenses (present or present-future, and past). The English "future" usually refers to a periphrastic form involving the auxiliary verb will (or sometimes shall when used with a first-person subject). There also exist other ways of referring to future circumstances, including the going to construction, and the use of present tense forms. For particular grammatical contexts where the present tense substitutes for the future, see conditional sentences and dependent clauses. For discussion and comparison of the various ways of making future reference in English, see going-to future.
For specific uses of future constructions formed with will/shall, see future.
Future-in-the-past
A "future-in-the-past" tense (or form) is sometimes referred to. This takes essentially the same form as the conditional, that is, it is made using the auxiliary would (or sometimes should in the first person).
This form has a future-in-the-past meaning in sentences such as She knew that she would win the game. Here the sentence as a whole refers to some particular past time, but would win refers to a time in the future relative to that past time.
Active and Passive Voice
The active voice (where the verb's subject is understood to denote the doer, or agent), of the denoted action) is the unmarked voice in English.
To form the passive voice (where the subject denotes the undergoer, or patient), of the action), a periphrastic construction is used.
In the canonical form of the passive, a form of the auxiliary verb be (or sometimes get) is used, together with the past participle of the lexical verb. Passive voice can be expressed in combination together with tenses, aspects and moods, by means of appropriate marking of the auxiliary (which for this purpose is not a stative verb, i.e. it has progressive forms available).
For example:
- This room is tidied regularly. (simple present passive)
- It had already been accepted. (past perfect passive)
- Dinner is being cooked right now. (present progressive passive)
The passive forms of certain of the combinations involving the progressive aspect are quite rare; these include the present perfect progressive (it has been being written), past perfect progressive (it had been being written), future progressive (it will be being written), future perfect progressive (it will have been being written), conditional progressive (it would be being written) and conditional perfect progressive (it would have been being written). Because of the awkwardness of these constructions, they may be paraphrased, for example using the expression in the process of (it has been in the process of being written, it will be in the process of being written, and similar).
The uses of these various passive forms are analogous to those of the corresponding tense–aspect–mood combinations in the active voice.
Word Order
The primary word orders that are of interest are
- the constituent order of a clause, namely the relative order of subject, object, and verb;
- the order of modifiers (adjectives, numerals, demonstratives, possessives, and adjuncts) in a noun phrase;
- the order of adverbials.
Constituent word order is defined in terms of a finite verb (V) in combination with two arguments, namely the subject (S), and object (O).
There is a difference between grammatical word order and natural word order. In many languages, topicalization and questions can change the grammatical word order.
Examples
A: [Kate loves who/Who does Kate love?] (SVO/OSV)
B: [She loves Mark/Mark is who she loves.] (SVO/OSV)
In the (A) sentences, the first one is used when putting emphasis on who Kate loves, and the second is used with more of a quizzical tone. English uses stress and tone to emphasize different aspects of the sentences, which can also change the word order, as shown above.
In the (B) sentences, the first one is more likely to be used by a native English speaker. The second sentence is grammatical as well, but less likely to be said in natural speech. This is because English uses the SVO structure in regular sentences, but is able to answer questions using the same structure that was used in the sentence.
In English, you can change the word order depending on what you want to emphasize.
Participle
Participles are verb forms that do double duty — they help build tenses and voices, but they also work as adjectives and adverbs. Understanding both types of participles is essential for forming correct verb tenses, using the passive voice, and writing more sophisticated sentences.
The Two Participles
English has two participles:
- Present participle — formed by adding -ing to the base verb: doing, running, sleeping. It's identical in form to the gerund, but serves a different function (more on that below).
- Past participle — for regular verbs, it's the -ed form (walked, boiled). For irregular verbs, it varies widely: done, written, sung, gone.
How the Present Participle Is Used
- Progressive tenses: She is reading a book.
- As an adjective: The woman sitting by the window is my boss.
- As an adverb: Looking up from his phone, he noticed the bus had arrived.
- In absolute constructions (with its own subject): The weather being terrible, we cancelled the trip.
Present participles used as adjectives carry an active meaning — an exciting movie is one that excites you.
How the Past Participle Is Used
- Perfect tenses: They have finished the project.
- Passive voice: The email was sent this morning.
- As an adjective: The broken window needs replacing.
- Adverbially: Exhausted from the hike, we fell asleep immediately.
Past participles used as adjectives usually carry a passive meaning — the attached file is one that has been attached. However, past participles of intransitive verbs can have active meaning: fallen leaves (leaves that have fallen).
Participle vs. Gerund
Both the present participle and the gerund end in -ing, but they do different jobs. The participle acts as an adjective or adverb; the gerund acts as a noun.
- ✅ Swimming in the lake, she felt completely free. (participle — describes she)
- ✅ Swimming is her favourite hobby. (gerund — subject of the sentence)
The famous example Flying planes can be dangerous is ambiguous: flying could be a gerund ("the activity of flying planes") or a participle ("planes that fly").
Self-check: If you can replace the -ing word with a noun like "it" or "the activity," it's a gerund. If it describes a noun or tells you more about an action, it's a participle.
Watch Out: Past Tense vs. Past Participle
For regular verbs, the past tense and past participle look the same (walked, played). For many irregular verbs, they differ:
- ✅ I went home early. (past tense)
- ✅ I have gone home early. (past participle)
- ❌ I should have went home early.
If you're unsure, check whether the verb follows a helping word like have, has, or had — if it does, you need the past participle form.

B1 | Intermediate
B1 is the intermediate level of the Common European Framework of Reference for Languages (CEFR). It marks the point where you move beyond survival English and start expressing yourself with real independence — describing experiences, explaining opinions, and handling everyday situations without a script.
What a B1 user can do
At this level, you're expected to:
- Understand the main points of clear, standard speech and writing on familiar topics — work, school, travel, hobbies.
- Handle most travel situations in English-speaking environments.
- Produce simple connected text on topics you know or care about.
- Describe experiences, events, hopes, and plans, and give brief reasons and explanations for your opinions.
- Communicate in routine tasks that require a straightforward exchange of information.
What B1 grammar looks like
B1 is where grammar starts to get more layered. You're not just forming basic sentences anymore — you're combining ideas, using different tenses with more precision, and starting to handle structures like the passive voice, modal verbs for necessity and possibility, and gerunds vs. infinitives. You're also expected to build complex sentences with linking words and dependent clauses.
Typical B1 grammar areas include:
- Future tenses — distinguishing will, going to, and the present continuous for future plans
- Passive voice — The report was written yesterday.
- Modal verbs — You should apply early. / She might be late.
- Used to — I used to live in Berlin.
- Verb patterns — knowing whether a verb takes a gerund, an infinitive, or both (I enjoy reading vs. I decided to leave)
What B1 doesn't mean
B1 speakers still hesitate, make grammatical errors, and sometimes struggle with less familiar topics. That's normal. The key difference from A2 is that you can keep a conversation going and get your point across even when things aren't perfect. The step up to B2 involves handling more abstract topics, understanding nuance, and producing more complex, accurate language.
Self-check: Can you tell a friend about a recent trip — what happened, what you liked, and what you'd do differently — without switching to your native language? If yes, you're likely operating at B1 or above.
