Choose the correct word to complete the sentence.
If you ___ earlier, you wouldn’t have missed the bus.
The correct answer is had left.
This is a third conditional sentence, referring to a hypothetical situation in the past: "If + past perfect, ... would have + past participle".
Conditional Sentence
As is typical for many languages, full conditional sentences in English consist of a condition clause or protasis specifying a condition or hypothesis, and a consequence clause or apodosis specifying what follows from that condition. The condition clause is a dependent clause, most commonly headed by the conjunction if, while the consequence is contained in the main clause of the sentence. Either clause may appear first.
Different types of conditional sentences (depending largely on whether they refer to a past, present or future time frame) require the use of particular verb forms (tenses and moods) to express the condition and the consequence. In English language teaching the most common patterns are referred to as first conditional, second conditional and third conditional; there is also a zero conditional and mixed conditional.
Modal Verb
English has the modal verbs can, could, may, might, must, shall, should, will, would, and also (depending on classification adopted) ought (to), dare, need, had (better), used (to). These do not add -s for the third-person singular, and they do not form infinitives or participles; the only inflection they undergo is that to a certain extent could, might, should and would function as preterites (past tenses) of can, may, shall and will respectively.
A modal verb can serve as the finite verb introducing a verb catena, as in "he might have been injured then". These generally express some form of modality (possibility, obligation, etc.), although will and would (and sometimes shall and should) can serve – among their other uses – to express future time reference and conditional mood.
Subjunctive Mood
The subjunctive mood in English is used to form sentences that do not describe known objective facts, but rather wishes or hypothetical suppositions. These include statements about one's state of mind, such as opinion, belief, purpose, intention, or desire. The subjunctive mood, such as She suggests that he speak English, contrasts with the indicative mood, which is used for statements of fact, such as He speaks English.
In Modern English, the subjunctive form of a verb often looks identical to the indicative form, and thus subjunctives are not a very visible grammatical feature of English. For most verbs, the only distinct subjunctive form is found in the third person singular of the present tense, where the subjunctive lacks the -s ending: It is necessary that he see a doctor (contrasted with the indicative he sees). The verb be, however, has not only a distinct present subjunctive (be, as in I suggest that he be removed) but also a past subjunctive were (as in If he were rich, ...).
These two tenses of the subjunctive have no particular connection in meaning with present and past time. Terminology varies; sometimes what is called the present subjunctive here is referred to simply as the subjunctive, and the form were may be treated just as an alternative irrealis form of was rather than a past subjunctive.
Another case where present-subjunctive forms are distinguished from indicatives is when they are negated: compare I recommend that they not enter the competition (subjunctive) with I hope that they do not enter the competition (indicative).
Past Subjunctive Mood
The only distinct past subjunctive form in English (i.e., form that differs from the corresponding past indicative) is were, which differs when used with a first or third person singular subject (where the indicative form is was). As with the present subjunctive, the name past subjunctive refers to the form of the verb rather than its meaning; it need not (and in fact usually does not) refer to past time. The main use of the past subjunctive form, were, which is also known as the irrealis is in counterfactual if clauses:
- If I were your wife, I would put poison in your coffee. [Attributed to Lady Astor, speaking to Winston Churchill]
The simple (indicative) past form was is very common in sentences of this type, though the Random House College Dictionary states "Although the [were] subjunctive seems to be disappearing from the speech of many, its proper use is still a mark of the educated speaker." When were is used, an inverted form without if is possible; this is not possible with was.
A common expression involving were is if I were you. The same principles of usage apply to the compound past subjunctive form were to..., which appears in second conditional condition clauses, usually with hypothetical future reference:
- If she were to go... or Were she to go... (equivalent to if she went)
The past subjunctive form may be used similarly to express counterfactual conditions after suppose, as if, as though, unless, imagine etc.
- Suppose that I were there now.
- She looks as though she were going to kill him.
- Try to imagine he were here.
- Try to imagine a tool that** made** that easy for citizens.
There is also the set expression as it were.
The past subjunctive can also be used in some that clauses expressing a wish contrary to fact or unlikely to be fulfilled:
- I wish [that] he were here now.
- If only the door were unlocked.
- I would rather [that] she were released.
- Would that it were true!
- Oh that it were so.
However, the use of the subjunctive with words such as wish is seldom obligatory. The example with would rather can be cast in the present subjunctive, expressing greater confidence that the action is feasible:
- I would rather she be released.
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.
