Mixed Grammar MCQ Test With Answers + PDF Exercise 020

To agree with a positive sentence, use so + auxiliary + subject: So do my brothers. The verb speak is present simple, so the auxiliary is do. Not my brothers do, because after so the auxiliary comes before the subject.

To agree with a positive sentence, use so + auxiliary + subject. Went is past simple, so we use did: So did my friend.

To agree with a negative sentence, use either at the end: my friend can't either. Not neither, because can't neither has two negatives. Neither goes at the start: neither can my friend.

With send somebody something, the person comes straight after the verb with no preposition: sent him a letter. With to, the person goes at the end: sent a letter to him.

The answer is a group of people (Engineers), so we ask with Who. Here who is the subject of the question. Not Whom, because whom is only for the object, never the subject.

We ask about the person you write to, which is the object of the preposition to. So we use Whom, a formal word for the object (in everyday English, Who is also common). What is for things, not people.

That starts a relative clause about the hat: a hat that is red. Not it, because that would make two sentences joined with no linking word.

Who starts a relative clause about a person: a friend who plays football. Not he, because you can't join two clauses with a pronoun alone.

That starts a relative clause about the pictures: pictures that were very interesting. Not they, because they can't join the two clauses.

In an indirect question after Do you know where…, use normal statement word order (subject before verb): where we can get. Not can we get, because that is direct question order.

After it is + adjective, use to + base verb: Is it difficult to learn English? Not speak alone, because to is missing.

After how in this kind of sentence, use to + base verb: I don't understand how to do the homework. We say do homework, not write or read homework.

Whose shows possession: the house belongs to my friend, so my friend whose house is near mine. Not who's, because that means who is.

We are asking who owns the car, so we use whose + noun: Do you know whose car that is? Not how fast, because how fast car that is is not correct English. You would need how fast that car is.

Use the past continuous (was raining) for an action in progress at a moment in the past (when I woke up). Not is raining, because this morning… woke up is in the past.

When links a longer past action (was sleeping) with a short action that interrupted it (the alarm rang).

This is the second conditional: if + past simple, then would + base verb. Before to see, we need would be able. Not would, because would to see is wrong; would is followed by a verb without to.

Until means 'up to the time when': we will keep working, and we will stop when we solve it. Not by, because by is followed by a time or noun, not a clause like we solve it.

In look forward to, the word to is a preposition, so it is followed by the -ing form: I look forward to visiting you. Not to visit, a very common mistake.

Too + adjective + to + verb means the quality is so great that something is not possible: too stupid to understand. Not stupid enough, because enough means he has as much of the quality as is needed, which makes no sense here.
