Gerunds and Infinitives
It can be a little difficult to know when to use gerunds and infinitives.
(See all the gerund and infinitive exercises here).
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?
