Here's my video on the subject:
We use gerunds (verb + ing):
- After certain verbs - I enjoy singing.
- After prepositions - I drank a cup of coffee before leaving.
- As the subject or object of a sentence - Swimming is good exercise.
We use 'to' + infinitive:
- After certain verbs - We decided to leave.
- After many adjectives - It's difficult to get up early.
- To show purpose - I came to London to study English.
We use the bare infinitive (the infinitive without 'to'):
- After modal verbs - I can meet you at six o'clock.
- After 'let', 'make' and (sometimes) 'help' - The teacher let us leave early.
- After some verbs of perception (see, watch, hear, notice, feel, sense) - I watched her walk away.
- After expressions with 'why' - Why go out the night before an exam?
