Gerunds after Prepositions

This is a good rule. It has no exceptions!

If we want to use a verb after a preposition, it must be a gerund. It is impossible to use an infinitive after a preposition. So for example, we say:

• I will call you after arriving at the office.
• Please have a drink before leaving.
• I am looking forward to meeting you.
• Do you object to working late?
• Tara always dreams about going on holiday.

Notice that you could replace all the above gerunds with "real" nouns:

• I will call you after my arrival at the office.
• Please have a drink before your departure.
• I am looking forward to our lunch.
• Do you object to this job?
• Tara always dreams about holidays.

The above rule has no exceptions!

So why is "to" followed by "driving" in 1 and by "drive" in 2?

1. I am used to driving on the left.
2. I used to drive on the left.

Answer

to as preposition	Preposition
I am used	to	driving on the left.
I am used	to	animals.
to as infinitive	Infinitive
I used	to drive	on the left
I used	to smoke.
