5.2.
Use
to/Used to
There is a little confusion on how to use the
words use to and used
to. One reason for the confusion is that it is
sometimes used as a verb, and sometimes used as an adjective. The other reason
is because it seems like the tense changes. It's really quite simple when you
look at it.
Used as an adjective.
Use to be + used to. This means to be accustomed
to. For example- I can study with the TV on. I am used to it. It
means I am accustomed, adjusted, or don't mind having the TV play while I'm
studying.
Or another example- Tim
had a hard time living in Tokyo. He wasn't used to so many
people. Tim didn't have experience being with big crowds of people
before.
Used as a verb. Use to + verb is a regular verb and
means something that happened but doesn't happen any more. It uses -ed to
show past tense. But since it always means something that happened in the past,
it should always use past tense. For example- I used to go
to school in Paris.(I went to school there before, but now I don't.) Or, When
Joshua was a child, he used to climb trees. (Now he
doesn't climb trees.)
Remember, we always use
this word when talking about the past. So when do you use use towithout
the d at the end? When the base form of the verb is used. Look
at these examples- She didn't use to swim before noon. (Now
she does swim before noon.) Or Did your father use to ride
a horse? In these cases the past tense is shown with the did and didn't.
