used to,be/get used to的用法区别
1．used to可看作一个半助动词或情态动词,其后跟动词原形,表示过去的习惯或经常发生的动作,例如：
When he was a child,he used to ask lots of questions.
I want to know the places (that/which) he used to go to.
否定式为：used not to(书面语),use(d)n’t to(口语),didn’t use to(口语)
疑问式为：Used sb to (书面语),Did sb use to (口语)
反意疑问句式为：use(d)n’t sb?(书面语) didn’t sb?(口语)
2．be used to = get used to 都是一个固定的结构,意思为：习惯于某事或做某事的意思,to为介词,后接名词或动名词,不能跟动词原形,例如：
We are used to the weather in the south of China.
They have got used to getting up early in the morning.
be used to的各种形式变化如下：
疑问式为：Be(具体形式) sb ….否定式为：sb be(具体形式) not …
反意疑问式为：be(具体形式) not sb?（be作为系动词看待）
get used to的各种形式变化如下：
疑问式为：Do/Does/Did sb get 否定式为：sb does/do/did not get …
反意疑问式为：do/does/did not sb?（get作为行为动词看待）
3．be used to + Verb或as/for接名词,表示某东西被用来作某事或当什么东西来使用,是一个被动语态的结构,例如：
This knife is usually used to cut fruit.
This magazine was used as a fan last night because of the hot weather.
Blooms are used for cleaning the floor when we do general cleaning.
由于be为助动词,因此它的疑问式、否定式及反意疑问式则按一般规则进行变化.
注意used to与would的区别：
(1)．used to重在表示与现在的对比,含“过去曾经/一度,现在未必”之意；would重在叙述过去的情况,没有上述含义.如可以说：
He used to get up early,but not now.但不说：He would get up early,but …
(2)．used to可以表示过去习惯或经常的状态；would不能,它只能表示过去的一个经常重复的动作,如可以说：
There used to be a temple nearby.但不能说：There would be …
(3)．used to较正规、普通,多用于口语；would不太正规、多用于书面语.
(4)．两者都不能用于表示某事发生的具体次数.但would可表示过去有时或偶尔发生的动作,因而可与sometimes,now and then,from time to time等时间状语连用,例如：
He would sit there for hours sometimes,doing nothing at all.
补充练习：用used to,be/get used to填空：
1．I am surprised to see you smoking; you didn’t _______________ .
2．There ________________ be a station here,didn’t there?
3．He ______________ living in the country.
4．This book _____________________ be very popular.
5．It _________ not ___________ be so cold in winter in former years.
6．I _______________ these cigarettes now that I can’t enjoy any others.
7．People ____________________ think that the earth was flat.
8．__________ you ______________ swim every day when you were children?
9．It’s hard to understand him if you _________ not _____________ their accent.
10． He __________ not ___________ being treated like that.
11． Dictionary can’t ___________________ to learn English well in class but __________________ a tool to help you with your English.
12． Recorders ________________ for playing tapes in the English class now.
