In part 1, we looked at when to use "to" and when to use "-ing" but there are some situations when we use the infinitive without "to" and that's what you can learn in part 2.
After make and let, we use the infinitive without "to". There is also an object between the two verbs. make/let + somebody + infinitive (no "to")
My mother makes me do my homework before I can watch TV.
The teacher lets me use a dictionary in class.
After help, we use the infinitive with or without "to".
I helped cook the dinner.
I helped to cook the dinner.
I helped my mother cook the dinner.
I helped my mother to cook the dinner.
After modal verbs, we also use the infinitive with "to". These verbs are can, could, may, might, must, shall, should, will and would.
I might go to London at the weekend.
I can play the piano but I can't read music.
Some books list have to and ought to as modal verbs but others do not. I would say they are not true modals. With these, of course, you do need "to".
I have to finish my homework before Friday.
