For example, the word "driving" is a gerund in this sentence:
- Driving a car is not easy at all!
But it is not in this sentence:
- Look! He's driving and talking on the phone.
a) After prepositions
We use gerunds when the verb is immediately after a preposition.
- He's looking forward to
seeinghis family again.
- I'm thinking of
b) As subjects
We use gerunds when we are talking about an action or activity in a general way.
- I like
lyingon the beach.
Usinggerunds is not hard.
