Choose the passive voice form of the following sentence: "They will deliver the package tomorrow."
Answers:
To transform the future simple sentence into passive voice, use the auxiliary verb "will be" and the past participle "delivered." The subject becomes "the package," and the verb "to deliver" changes to "will be delivered."
Simple Future
The term simple future, future simple or future indefinite, as applied to English, generally refers to the combination of the modal auxiliary verb will with the bare infinitive of the main verb.
Sometimes (particularly in more formal or old-fashioned English) shall is preferred to will when the subject is first person (I or we).
The auxiliary is often contracted to _ 'll_.
This construction can be used to indicate what the speaker views as facts about the future, including confident predictions:
- The sun will rise tomorrow at 6:14.
- It will rain later this week.
It may be used to describe future circumstances that are subject to some condition:
- He will go there if he can.
However English also has other ways of referring to future circumstances. For planned or scheduled actions the present progressive or simple present may be used. There is also a going-to future, common in colloquial English, which is often used to express intentions or predictions (I am going to write a book some day; I think that it is going to rain). Use of the will/shall construction when expressing intention often indicates a spontaneous decision:
- I know! I'll use this book as a door stop.
Compare I'm going to use..., which implies that the intention to do so has existed for some time.
Use of present tense rather than future constructions in condition clauses and certain other dependent clauses is described below under and. The modal verbs will and shall also have other uses besides indicating future time reference. For example:
- I will pass this exam. (often expresses determination in addition to futurity)
- You will obey me! (insistence)
- I will not do it! (negative insistence, refusal)
- At this moment I will tolerate no dissent. (strong volition)
- He hasn't eaten all day; he will be hungry now. (confident speculation about the present)
- One of his faults is that he will make trouble unnecessarily. (habit)
- Shall we get to work? (suggestion)
Future Progressive
The future progressive or future continuous combines progressive aspect with future time reference; it is formed with the auxiliary will (or shall in the first person, the bare infinitive be, and the present participle of the main verb.
It is used mainly to indicate that an event will be in progress at a particular point in the future:
- This time tomorrow I will be taking my driving test.
- I imagine we will already be eating when you arrive.
The usual restrictions apply, on the use both of the future and of the progressive: simple rather than progressive aspect is used with some stative verbs, and present rather than future constructions are used in many dependent clauses. The same construction may occur when will or shall is given one of its other uses, for example:
- He will be sitting in his study at this time. (confident speculation about the present)
Future Perfect
The future perfect combines aspect with future time reference.
It consists of the auxiliary will (or sometimes shall in the first person, as above), the bare infinitive have, and the past participle of the main verb.
It indicates an action that is to be completed sometime prior to a future time of perspective, or an ongoing action continuing up to a future time of perspective (compare uses of the present perfect above).
- I shall have finished my essay by Thursday.
- When I finally search him he will have disposed of the evidence.
- By next year we will have lived in this house for half a century.
For the use of the present tense rather than future constructions in certain dependent clauses.
The same construction may occur when will or shall is given one of its other meanings; for example:
- He will have had his tea by now. (confident speculation about the present)
- You will have completed this task by the time I return, is that understood? (giving instruction)
Future Perfect Progressive
The future perfect progressive or future perfect continuous combines perfect progressive aspect with future time reference.
It is formed by combining the auxiliary will (or sometimes shall, as above), the bare infinitive have, the past participle been, and the present participle of the main verb.
Uses of the future perfect progressive are analogous to those of the present perfect progressive, except that the point of reference is in the future. For example:
- He will be very tired because he will have been working all morning.
- By 6 o'clock we will have been drinking for ten hours.
For the use of present tense in place of future constructions in certain dependent clauses.
The same construction may occur when the auxiliary (usually will) has one of its other meanings, particularly expressing a confident assumption about the present:
- No chance of finding him sober now; he*'ll have been drinking* all day.
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.
Simple
"Simple" forms of verbs are those appearing in constructions not marked for either progressive or perfect aspect (I go, I don't go, I went, I will go, etc., but not I'm going or I have gone).
Simple constructions normally denote a single action (perfective aspect), as in Brutus killed Caesar, a repeated action (habitual aspect), as in I go to school, or a relatively permanent state, as in We live in Dallas. They may also denote a temporary state (imperfective aspect), in the case of stative verbs that do not use progressive forms.
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.

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.
