英语词组问题....be used toused toget used to这几个有什么区别啊?到底要怎么用?.

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。Key:1。use to 2。used to 3。(has) got/is/was used to 4。used to 5。used,to/did,use to 6。am used to/ have been/got used to 7。used to 8。Used,to/Did,use to 9。are,used to/do,get used to 10。is,used t/does,get used to 11。be used,(can be used) as 12。are used （有的答案不止一个）
