Choose the correct form of the verb "to travel" in the following sentence.
As soon as he _________________________ his passport, he _________________________ to Europe.

The original sentence requires the simple present tense in the first part and the simple future tense in the second part. The simple present tense is used in the dependent clause (as soon as he gets his passport) to express a future event that is expected to happen before another future event. The simple future tense is used in the main clause (he will travel to Europe) to express a future action. The correct answer is "As soon as he gets his passport, he will travel to Europe."

Simple Present

The simple present or present simple is a form that combines present tense with "simple" (neither perfect nor progressive) aspect.

In the indicative mood it consists of the base form of the verb, or the -s form when the subject is third-person singular (the verb be uses the forms am, is, are). However, with non-auxiliary verbs it also has a periphrastic form consisting of do (or third-person singular does) with the bare infinitive of the main verb — this form is used in questions (and other clauses requiring inversion and negations, and sometimes for emphasis.

The principal uses of the simple present are given below.

To refer to an action or event that takes place habitually. Such uses are often accompanied by frequency adverbs and adverbial phrases such as always, often, from time to time and never.
Examples:

  • I always take a shower.
  • He writes for a living.

This contrasts with the present progressive, which is used for actions taking place at the present moment.

With stative verbs in senses that do not use progressive aspect, to refer to a present or general state, whether temporary, permanent or habitual. (In senses that do use progressive aspect, the present simple is used when the state is permanent or habitual.)

  • You are happy.
  • I know what to do.
  • Denmark lies to the north of Germany.

When quoting someone or something, even if the words were spoken in the (usually very recent) past:

  • The label says "External use only".
  • Mary says she's ready.

To refer to a single completed action, as in recounting the events of a story in the present tense (see historical present), and in such contexts as newspaper headlines, where it replaces the present perfect:

  • In Hamlet, Ophelia drowns in a stream.
  • 40-year-old wins gold medal.

Sometimes to refer to an arranged future event, usually with a reference to time:

  • We leave for Berlin tomorrow at 1 pm.

In providing a commentary on events as they occur, or in describing some theoretical sequence of events:

  • I chop the chives and add them to the mixture.
  • According to the manager's new idea, I welcome the guests and you give the presentation.

In many dependent clauses referring to the future, particularly condition clauses, clauses expressing place and time, and many relative clauses (see below):

  • If he finds your sweets, he will eat them.
  • We will report as soon as we receive any information.

In certain situations in a temporal adverbial clause, rather than the present progressive:

  • We can see the light improving as we speak.

In colloquial English it is common to use can see, can hear for the present tense of see, hear, etc., and have got for the present tense of have (denoting possession.

See have got and can see below.

For the present subjunctive, see subjunctive.

For uses of modal verbs (which may be regarded as instances of the simple present) see modal verbs.

Present progressive

The present progressive or present continuous form combines present tense with progressive aspect. It thus refers to an action or event conceived of as having limited duration, taking place at the present time. It consists of a form of the simple present of be together with the present participle of the main verb and the ending -ing.

  • We are cooking dinner now.

This often contrasts with the simple present, which expresses repeated or habitual action (We cook dinner every day). However, sometimes the present continuous is used with always, generally to express annoyance about a habitual action:

  • You are always making a mess in the study.

Certain stative verbs do not use the progressive aspect, so the present simple is used instead in those cases. The present progressive can be used to refer to a planned future event:

  • We are tidying the attic tomorrow.

It also appears with future reference in many condition and time clauses and other dependent clauses:

  • If he*'s sleeping* when you arrive, wake him up.
  • I will finish the job while the children are playing.

It can also refer to something taking place not necessarily at the time of speaking, but at the time currently under consideration, in the case of a story or narrative being told in the present tense (as mentioned above under present simple):

  • The king and queen are conversing when Hamlet enters. For the possibility of a present subjunctive progressive, see English subjunctive.

Present Perfect

The present perfect (traditionally called simply the perfect) combines present tense with perfect aspect, denoting the present state of an action's being completed, that is, that the action took place before the present time. (It is thus often close in meaning to the simple past tense, although the two are not usually interchangeable.) It is formed with the present tense of the auxiliary have (namely have or has) and the past participle of the main verb.

The choice of present perfect or past tense depends on the frame of reference (period or point in time) in which the event is conceived as occurring. If the frame of reference extends to the present time, the present perfect is used. For example:

  • I have written a letter this morning. (if it is still the morning)
  • He has produced ten plays. (if he is still alive and professionally active)
  • They have never traveled abroad. (if they are still alive and considered capable of traveling)

If the frame of reference is a time in the past, or a period that ended in the past, the past tense is used instead. For example:

  • I wrote a letter this morning (it is now afternoon);
  • He produced ten plays (he is now dead or his career is considered over, or a particular past time period is being referred to);
  • They never traveled abroad (similarly).

See Simple past for more examples.

The simple past is generally used when the occurrence has a specific past time frame – either explicitly stated (*I wrote a book in 1995; *the water boiled a minute ago), or implied by the context (for example, in the narration of a sequence of events). It is therefore normally incorrect to write a sentence like I have written a novel yesterday; the present perfect cannot be used with an expression of past time such as yesterday.

With already or yet, traditional usage calls for the present perfect: ''Have you eaten yet? Yes, I've already eaten.* However, current informal American speech tends to use the simple past: *Did you eat yet? Yes, I ate already.''

Use of the present perfect often draws attention to the present consequences of the past action or event, as opposed to its actual occurrence. The sentence she has come probably means she is here now, while the simple past she came does not. The sentence, "Have you been to the fair?" suggests that the fair is still going on, while the sentence, "Did you go to the fair?" could mean that the fair is over. (See also been and gone below.) Some more examples:

  • I have eaten. (implies that I'm no longer hungry)
  • We have made the dinner. (implies that the dinner is now ready to eat)
  • The weather has gotten cloudier. (implies that it is now more cloudy than previously)

It may also refer to an ongoing state or habitual action, particularly in saying for how long, or since when, something is the case. For example:

  • I have lived in Paris for five years.
  • He has held the record since he won his Olympic gold.
  • We have eaten breakfast together every morning since our honeymoon.

This implies that I still live in Paris, that he still holds the record and that we still eat together every morning (although the first sentence may also refer to some unspecified past period of five years).

When the circumstance is temporary, the present perfect progressive is often appropriate in such sentences (see below); however, if the verb is one that does not use the progressive aspect, the basic present perfect is used in that case too:

  • Amy has been on the swing for ten minutes.

The present perfect may refer to a habitual circumstance, or a circumstance being part of a theoretical or story narrative being given in the present tense (provided the circumstance is of an event's having taken place previously):

  • Whenever I get home, John has usually already arrived.
  • According to the plan, the speeches have already been given when the cake is brought out.

The present perfect may also be used with future reference, instead of the future perfect, in those dependent clauses where future occurrence is denoted by present tense. For example:

  • When you have written it, show it to me.

Present Perfect Progressive

The present perfect progressive (or present perfect continuous) construction combines some of this perfect progressive aspect with present tense.

It is formed with the present tense of have (have or has), the past participle of be (been), and the present participle of the main verb and the ending "-ing"

This construction is used for ongoing action in the past that continues right up to the present or has recently finished:

  • I have been writing this paper all morning.
  • Why are his eyes red? He has been crying.

It is frequently used when stating for how long, or since when, something is the case:

  • She has been working here since 1997.
  • How long have you been sitting there?
  • They have been arguing about it for two weeks.

In these sentences the actions are still continuing, but it is the past portion of them that is being considered, and so the perfect aspect is used. (A sentence without perfect aspect, such as I am sitting here for three hours, implies an intention to perform the action for that length of time.)

With stative verbs that are not used in the progressive, and for situations that are considered permanent, the present perfect (nonprogressive) is used instead.

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.

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.

A2 | Elementary | Pre-intermediate

CEFR A2 is the second level in the Common European Framework of Reference for Languages, often called elementary or pre-intermediate. If you're at this stage, you've moved beyond the basics of A1 and can handle simple, real-life communication — but you're still building the foundations you'll need for B1 and beyond.

What can an A2 learner do?

At A2, you can:

  • Understand everyday expressions related to familiar topics — personal details, family, shopping, work, and your local area.
  • Communicate in routine situations that involve a simple, direct exchange of information (e.g. ordering food, asking for directions, making small talk).
  • Describe your background and immediate environment in simple terms — where you live, what you do, what you need.
  • Read and understand short, simple texts like signs, menus, timetables, and brief personal messages.

Key grammar at A2

At this level, you're expected to be comfortable with several core grammar areas:

  • Past simple and past continuous — talking about completed actions and actions in progress in the past.
  • Present perfect — connecting past events to the present (I've visited London twice).
  • Basic modal verbs — expressing ability, permission, necessity, and possibility (can, must, should, have to).
  • Common question forms — both simple and slightly more complex (How long have you lived here?).
  • Articles and determiners — using a/an/the correctly, along with words like some, any, few, little.
  • Basic conditionals — first conditional and simple uses of if and wish.

You're also expanding your vocabulary through collocations (natural word pairings like make a decision or take a break) and learning to use gerunds and infinitives with common verbs.

How A2 differs from A1 and B1

Compared to A1, A2 learners can do more than just produce isolated phrases — you can link simple sentences and participate in short conversations. Compared to B1, you're still relying on familiar contexts and predictable language; handling unexpected topics or expressing opinions in detail comes at the next level.

Self-check: If you can describe your daily routine, talk about past experiences, and handle a basic conversation at a shop or restaurant — but struggle when the topic gets abstract or unfamiliar — you're likely at A2.
