1. Used to

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.

When Joshua was a child, he used toclimb 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.

Did your father use to ride a horse? 

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

ALWAYS FOLLOWED BY INFINITIVE.

I used to sleep in my aunt´s bed when visiting her.

2. To use- used- used

To do something using a machine, tool, skill, method etc in order to do a job or to achieve a result.

 To get a benefit for yourself from something that is availableto you.

To take an amount from a supply of something in order to do a job or to achieve a result.

To treat someone in an unfair way, for example by pretending to care about them so that they do what you want

Examples:

I used my hands for eating when I was a child.

She uses different methods for learning.

Did you use your new car last week?

3. To be used to.

We use 'be used to + verb-ing' to talk about things which feel normal for us or things that we are accustomed to:

• I'm used to getting up early, so I don't mind doing it (= getting up early is normal for me, it's what I usually do).
• My little daughter is used to eating lunch at noon. So she was grumpy yesterday when we didn't eat until one.

Note that we make the negative or the question with the verb 'be' in the normal way. The 'used to' doesn't change:

• Lucy isn't used to staying up late, so she's very tired today.
• Are your children used to walking a lot?

 We can also use 'be used to + noun', which has the same meaning:

• I've lived in the UK almost all my life, so I'm used to rain (= rain is normal for me).
• That football team always lose, so they're used to disappointment!

We can put the verb 'be' into any tense. So we can talk about things in the past or the future as well as the present using this expression:

• It was difficult when I first started university, because I wasn't used to the amount of work we had to do.
• Soon I'll be used to driving in London and I won't be so frightened!

We can use 'get used to + verb-ing' to talk about the change of not normal to normal. We can also use this in any tense:

• Don't worry if your new job is hard at first. You'll get used to it.
• It took me a while, but I got used to speaking another language every day.

ALWAYS FOLLOWED BY GERUND.

It took me a few months to be used to living in Japan. At first everything seemed very different, but then gradually it became normal for me.
