used to + infinitive
used to+不定式

We use?used to?to talk about things that happened in the past – actions or states – that no longer happen now.
我們用used to來(lái)談?wù)摪l(fā)生在過(guò)去的動(dòng)作或者狀態(tài)，而且是現(xiàn)在不再發(fā)生的事實(shí)?！皯T于、過(guò)去經(jīng)常”

例句：

·?She used to be a long distance runner when she was younger.

·?I used to eat meat but I became a vegetarian 5 years ago.

The negative is?didn’t use to?and questions are formed with?Did you use to …?
其否定形式是didn’t use to，問(wèn)句格式是Did you use to……

There is no present tense equivalent of used to. To talk about present habits we use the present simple and an adverb of frequency (usually, always, often, never, etc.) “used to“
沒(méi)有對(duì)應(yīng)的現(xiàn)在時(shí)態(tài)。當(dāng)談到現(xiàn)在的習(xí)慣的時(shí)候，我們用一般現(xiàn)在時(shí)和一個(gè)頻度副詞（usually，always，often，never等等）表示。

例如：
e.g.?I often eat at the Japanese restaurant in the city centre.

be/get used to

If you?are used to?something, you are accustomed to it – you don’t find it unusual. If you?get used to?something or you are getting used to?something you are becoming accustomed to it – it was strange, now it’s not so strange.
如果你are used to某事，表示你習(xí)慣于某事，你不覺(jué)得該事物不正常。如果你get used to某事物或者你are getting used to 某事物，你正在慢慢習(xí)慣該事物，過(guò)去覺(jué)得它很奇怪，現(xiàn)在不奇怪了。
