English Grammar Test B2 (Upper Intermediate)

This is a third conditional about an unreal past: if + past perfect, then would have + past participle. So: If we had left earlier, we wouldn't have missed the train.

To wish for a different present situation, use wish + past simple: I wish I knew. Know is a state verb, so the continuous form is not used.

Reported questions use statement word order (subject before verb) and no do or did. After a past reporting verb like asked, the tense usually moves back: “Where do you live?” → where I lived.

Reported commands use tell + object + to-infinitive: told us to turn off. Tell is not followed by an object + -ing form or base verb in this pattern.

Must have + past participle expresses a confident conclusion about the past. Can have is not used in affirmative statements of deduction; for possibility we use could have or may have.

Can't have + past participle means we are sure something did not happen. Modal verbs are never followed by to, so couldn't to have is wrong, and mustn't seen lacks have.

The documents do not sign anything; someone signs them, so we need a passive with a modal: must be + past participle (signed).

The teachers receive the action, so the verb is passive, and this year (a period that is not over) calls for the present perfect: have been hired. Teachers is plural, so has is wrong.

The causative have + object + past participle means someone else does the job for you: have my hair cut (a hairdresser cuts it). Get my hair cut means the same.

The future perfect (will have + past participle) describes something that will be complete by a point in the future. By next June is that point, and for ten years measures the time up to it.

This is a mixed conditional: an unreal past condition (had studied) with a present result. Now shows the result is in the present, so we use would + base verb: would be.

Suggest is followed by a that clause (in American English with the base verb) or by an -ing form (She suggested taking a taxi). It is never followed by a to-infinitive.

To express regret about the past, use wish + past perfect: I wish I hadn't eaten. Last night shows that the regret is about a finished past event.

Get used to + noun or -ing form means to become familiar with something over time. Used to + base verb is for past habits and cannot be followed directly by a noun like the cold.

This is a non-defining relative clause (set off by commas) about a person, so we use who. That cannot introduce a non-defining clause, and whom is an object form, while here the pronoun is the subject.
