tenses or infinitive/-ing forms?

[kacpersdz]

Hi everyone,

This is my first post on this forum. I hope to stay with you longer.

Let's start from the beginning. I've recently started TEFL course to keep myself occupied during the lock-down.
First part of the course is obviously grammar which I'm studying from Practical English Usage (by Michael Swan). Everything seems to be clear (despite so many rules and exceptions). I got to infinitives/participles topic and there's one thing I don't get:

IS there any rule when we should use tenses or infinitives/-ing forms?
Can we use those interchangeably?

Many thanks,

Kacper

Well, there are loads of rules about tense, but I don't really understand your question. Do you mean what rule tells us that only a) below is possible?

a) Yesterday I went to school. (tense)
b) Yesterday I to go to school. OR Yesterday I go to school. (infinitive)
c) Yesterday I going to school. (-ing form)
