If a preposition (in/for/about, etc.) is followed by a verb, the verb ends in -ing:
|Are you interested||in||working||for us?|
|I’m not very good||at||leaning||languages.|
|Sue must be fed up||with||staying||–|
|What are the advantages||of||having||a car?|
|Thanks very much||for||inviting||me to your party.|
|How||about||meeting||for lunch tomorrow?|
|Why don’t you go out||instead of||sitting||at home all the time?|
|Carol went to work||in spite of||feeling||sick|
You can also say “instead of somebody doing something.” “fed up with people doing something,” etc. :
– I’m fed up with people telling me what to do.
Note the use of the following prepositions + -ing:
before -ing and after -ing:
– Before going out, I called Sarah. (not Before to go out)
– What did you do after finishing school?
You can also say “Before I went out …” and “… after you finished school.”
by -ing (to say how something happens):
– The burglars got into the house by breaking a window and climbing in.
– You can improve your English by reading more.
– She made herself sick by not eating properly.
– Many accidents are caused by people driving too fast.
– We ran 10 miles without stopping
– It was a stupid thing to say. I said it without thinking.
– She needs to work without people disturbing her. (or … without being disturbed.)
– I have enough problems of my own without having to worry about yours.
To -ing (look forward to doing something, etc.)
To is part of the infinitive (to do / to see, etc.):
– We decided to go out.
– Would you like to meet for lunch tomorrow?
But to is also a preposition (like in/for/about/from, etc.). For example”
– We drove from Houston to Chicago.
– I prefer tea to coffee.
– Are you looking forward to the weekend?
If a preposition is followed by a verb, the verb ends in -ing:
in doing about meeting without stopping (etc.)
So, when to is a preposition and it is followed by a verb, you must say to -ing:
– I prefer driving to traveling by train. (not to travel)
– Are you looking forward to going on vacation? (not looking forward to go)
