Mixed Tenses Multiple Choice Test 4

This is a general routine, so we use the present simple: the doctors monitor. In the relative clause, the present perfect (has gotten, American English; British has got/has had) shows a transfusion that has already happened. Not had monitored / have got, because patient is singular and needs has.

How long + an action that started in the past and is still going on needs the present perfect continuous: have you been working. For advice we use If I were you, I would…, so I would give up. Not has, because the subject is you.

Tomorrow shows the future, so will receive. Can give expresses what will be possible then. Not might get / couldn't give, because getting your pay is a reason to give a loan, not to refuse one.

After It's been … since, we use the past simple for the moment in the past when something last happened: since I saw him. Next week shows a planned future action, so will be going (future continuous). Not had seen / went, because went is past and next week is future.

The incident is a finished past event, so caused (past simple). The workers' time together was before the incident, so we use the past perfect: hadn't worked together very long. Very long is normally used in negative sentences.

The lessons started in the past and are still going on, so we use the present perfect continuous: have been giving. The result up to now is hasn't been able to catch up. Not can't be able, because can and be able are never used together.

Was laughing (past continuous) describes what he was doing at that time. The jokes came before and caused the laughing, so we use the past perfect continuous: had been telling. Not laughed / to tell, because she to tell is not a correct verb form.

Both actions are finished and happened one after another in the past, so both verbs are past simple: met and gave. Not will meet / gave, because the two verbs joined by and must refer to the same time.

By the time + past simple (arrived) is followed by the past perfect for an action finished earlier: had prepared. Not arrived / will prepare, because the dinner was ready before I got home.

The question was asked at one moment in the past, so asked. In reported speech, What are you doing? becomes what he was doing, and I have become becomes he had become. Not was asking / done, because done needs an auxiliary (had done).

Recent discoveries with results now need the present perfect: there have been (plural, for many discoveries) and which have improved our lives. Not is / improve, because discoveries is plural.

Two finished actions in order (and then) are both in the past simple: put (irregular: put-put-put) and placed. Not had put / placing, because placing is not a complete verb.

Must have + object + past participle (have the house painted) means we need someone to do the job for us. Or else gives the result if we don't: it will not be done till next year. Not have to have / can be done, because the result should be negative.

Yet in a question shows the present perfect: Have you had the mumps yet? (have an illness). Come down with means become ill with; just came is American usage (British: has just come down). Not have / been, because we have an illness, we don't be it.

I am looking (present continuous) describes what I am doing now. It fell (past simple) is a short action that interrupted a longer one, as I was threading it (past continuous). Not have looked / has fallen, because the long action of threading needs the past continuous.

The speaker refuses an invitation, so can't go. The plans were made earlier and matter now, so we use the present perfect: have made plans. Not couldn't go / make, because I make plans doesn't show plans that already exist.

Yet in a negative sentence needs the present perfect: haven't found (find-found-found). The putting happened at a finished past time, so we ask in the past simple: Where did you put it? Not haven't find, because after have we need the past participle found.

Will be making (future continuous) describes an action that is planned or expected to be happening tomorrow. Last month shows a finished past time, so bought (past simple). Not will make / buy, because buy cannot refer to last month.

We aren't buying (present continuous) shows a decision about the near future. Know is a state verb, so the present simple is used: we don't know anything. Not aren't / know, because anything needs a negative verb here.

For plans we use be going to: Which hotel are you going to stay in? Can suggest is an offer. Yet needs the present perfect: if you haven't made reservations yet. Not will be suggesting / made, because made doesn't go with yet.
