Mn giúp mình bài này với ạ
Infinitives are forms like (to) do, (to) say. They are usually used with 'to', but not always.

Look at the following sentences which show the more common uses of the infinitive.

a I'm going to the pool to have my swimming lesson.

b I want to enrol for netball

practice next term.

c They are unlikely to hold the Olympics in Cambridge. d They let me do the judo

classes even though I had never done it before.

e You must not run with the ball in some sports.

f We encouraged them to run faster by cheering loudly.

Now say which of the above:

1 follows an adjective? 

2 follows a modal auxiliary? 

3 follows a main verb? 

4 is used to express purpose?

 5 has an infinitive without 'to'?

 6 follows the object of a verb?
