Why do we use -ing for a verb after be used to? Because we always use -ing for a
verb after a preposition - and the to is a preposition.
Use of Be used to
The be used to expression is for talking about something that is familiar to us
or easy for us. For example:
I am used to driving on the left.
It means that it is not a problem for me to drive on the left of the road. I am
Spanish. In Spain, people drive on the left. Now I am living in the UK where people
drive on the right. Of course, I drive on the right in the UK, but when I go to Spain
it is easy for me to drive on the left because "I am used to it".
Look at these examples.
I am used to hard work.
I am used to working hard.
He is not used to Madrid.
He isn't used to living in Dublin.
Are you used to fast food?
Are you used to eating fast food?
Tenses
We can use be used to in any tense. We just conjugate the verb be in the tense
that we need. Look at these examples:
When we lived in Seville, we were used to hot weather.
I have been used to commuting for a long time.
You will soon be used to living in the countryside.
