Use to/ Used to

There is a little confusion on how to use them.

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

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.

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

It 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.

I used to go to school in Paris. (I went to school there before, but now I don't.)

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 to without the d at the end? When the base form of the

verb is used.

She didn't use to swim before noon. (Now she does swim before noon.)

Did your father use to ride a horse?

(In these cases the past tense is shown with the did and didn't.)

You try...Use the correct form of use to. Decide if it is an adjective or verb. If it is a verb, does it use the base form of the verb, or does it need -ed?

1. Emily _____ play with dolls. Emily used to play with dolls (used to – verb) 2. Sheila wasn't ______ having to cook for herself. 3. Did Todd _______ go skiing in the Alps? 4. I never ________ get up so late. 5. His dog is ________ staying home alone all day. 6. We didn't ________ use to fight like this. 7. I wonder if you will ever be ________ working so hard. 8. She didn't ________ sing so well, did she? 9. Herbert ________ play basketball after school. 10. They aren't ________ staying out so late.
