used to是“过去曾经...”的意思 ，后接动词
比如：He used to be a teacher。他曾经是一名教师
I used to go swimming once a week。我曾经每周都去游泳

be used to是“习惯...”的意思 ，后接名词
比如：He is used to getting up early他习惯了早起

get used to表示“渐渐习惯....”与“be used to”不同，get used to强调的是由“不习惯”到“习惯”的这个过程，而“be used to”所强调的只是“习惯了”这个状态

比如：The food here is not so tasty but you will get used to that这里的伙食不怎么样，但你会慢慢习惯的
The food here is not so tasty but he is used to that这里的伙食不怎么样，但是他“已经”习惯了
Used to do
We use 'used to' for something that happened regularly in the past but no longer happens.
· I used to smoke a packet a day but I stopped two years ago.
· Ben used to travel a lot in his job but now, since his promotion, he doesn't.
· I used to drive to work but now I take the bus.
We also use it for something that was true but  no longer is.
· There used to be a cinema in the town but now there isn't.
· She used to have really long hair but she's had it all cut off.
· I didn't use to like him but now I do.
'Used to do' is different from 'to be used to doing' and 'to get used to doing'
to be used to doing
We use 'to be used to doing' to say that something is normal, not unusual.
· I'm used to living on my own. I've done it for quite a long time.
· Hans has lived in England for over a year so he is used to driving on the left now.
· They've always lived in hot countries so they aren't used to the cold weather here.
to get used to doing
We use 'to get used to doing' to talk about the process of something becoming normal for us.
· I didn't understand the accent when I first moved here but I quickly got used to it.
· She has started working nights and is still getting used to sleeping during the day.
· I have always lived in the country but now I'm beginning to get used to living in the city.

Had better
We use “had better” plus the infinitive without “to”  to give advice. Although “had” is the past form of “have”, we use “had better” to give advice about the present or future.
· You'd better tell her everything.
· I'd better get back to work.
· We'd better meet early.
The negative form is “had better not”.
· You'd better not say anything.
· I'd better not come.
· We'd better not miss the start of his presentation.
We use “had better” to give advice about specific situations, not general ones. If you want to talk about general situations, you must use “should”.
· You should brush your teeth before you go to bed.
· I shouldn't listen to negative people.
· He should dress more appropriately for the office.
When we give advice about specific situations, it is also possible to use “should”.
· You shouldn't say anything.
· I should get back to work.
· We should meet early.
However, when we use “had better” there is a suggestion that if the advice is not followed, that something bad will happen.
· You'd better do what I say or else you will get into trouble.
· I'd better get back to work or my boss will be angry with me.
· We'd better get to the airport by five or else we may miss the flight.

Should
We use 'should' for giving advice.
· You should speak to him about it.
· He should see a doctor.
· We should ask a lawyer.
We use 'should' to give an opinion or a recommendation.
· He should resign now.
· We should invest more in Asia.
· They should do something about this terrible train service.
'Should' expresses a personal opinion and is much weaker and more personal than 'must' or 'have to'. It is often introduced by ' I think'.
· I think they should replace him.
· I don't think they should keep the contract.
· Do you think we should tell her.

Should 2
We can use 'should' after 'reporting verbs' such as
demand  insist  propose  recommend  suggest
· He demanded that we should pay for the repair.
· She insisted that she should pay for the meal.
· I have proposed that he should take charge of the organization.
· The committee recommends that Jane should be appointed.
· We have suggested that Michael should be given a reward for his hard work.
However, it is also possible to say exactly the same thing by omitting the 'should' and just using the infinitive form without 'to' . Some people call this the 'subjunctive' form.
· He demanded that we pay for the repair.
· She insisted that she pay for the meal.
· I have proposed that he take charge of the organization.
· The committee recommends that Jane be appointed.
· We have suggested that Michael be given a reward for his hard work.
We can use 'should' after various adjectives. Typical examples are : 
funny  interesting  natural  odd  strange  surprised  surprising  typical
· It's funny that you should say that. I was thinking exactly the same thing.
· It's interesting that they should offer him the job. Not an obvious choice.
· It's natural that you should be anxious. Nobody likes speaking in public.
· Isn't it odd that he should be going to the same tiny hotel? What a coincidence.
· It's strange that you should think so. Nobody else does.
We can use 'should' in 'if clauses' when we believe that the possibility of something happening is small.
· If you should happen to see him before I do, can you tell him that I want to speak to him urgently?
· If there should be a problem, just give me a call and I'll sort it out.
· If anyone should ask where I am, say I'm in a meeting.
We use 'should' in various fixed expressions.

· What a fantastic present. You really shouldn't have.
To emphasize  a visible emotion
