• I¬† am used to¬†lots of noise.
  • I¬† am used to¬†working late.

be used to something
be used to doing

be used to is an expression. It is not a tense. If I say "I am used to Thailand", it is like saying "I am accustomed to Thailand."

Do not confuse be used to with with the special structure used to do. They have different meanings.

Structure of be used to

The structure of be used to is:

subject+main verb
be
+used to+object

Look at the structure again with positive, negative and question sentences:

 subjectmain verb
be
notused toobject
+Iam used tohorses.
-Heisnotused tochildren.
Wearen'tused tobig cities.
?Areyou used toher temper?

Note that if the object involves a verb, we use the -ing  form (-ing form):

  • I am not used to¬†being ¬†lied to.
  • He is used to¬†working¬†late.
  • We aren't used to¬†taking ¬†the bus.
  • Are you used to¬†cooking?
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 Japanese. In Japan, people drive on the left. Now I am living in the USA where people drive on the right. Of course, I drive on the right in the USA, but when I go to Japan 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¬†New York.
  • He¬† isn't used to¬†living in New York.
  • Are¬†you¬† used to¬†fast food?
  • Are¬†you¬† used to¬†eating quickly?

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 Bangkok, we¬†were ¬†used to hot weather.
  • I¬† have been¬†used to snakes for a long time.
  • You¬†will¬†soon¬†be ¬†used to living alone.
