初中英语used to与be used to的用法区别  【小编寄语】遥查字典英语网小编教给同学们的是初中英语used to与be used to的用法区别,一起来学习下吧!
祝同学们学习进步!
  一、在英国英语中传统上把used to看作是情态动词,因此,它的疑问式应当是:Used +主语+to sth.
?
否定式应当是used not to或use(d)n't to。
但是,在美国英语中,人们把used to看作是实义动词,因此,它的疑问式是:Did +主语+use to do sth.
?
否定式是:主语+didn't use.
.
.
由于受到美国英语的影响,甚至在英国英语中,人们也很少遥Used.
.
.
+主语+to.
.
.
这种疑问式,而遥Did +主语+use.
.
.
这一疑问式。
例如:   ①Did they use to play football?
他们过去踢足球吗?
  ②Did you use to smoke?
你过去吸烟吗?
  ③Did you use to take long walks in the countryside?
你过去在农村经常进行长距离的散步吗?
  二、在带有used to的陈述句后面,附加疑问句中一般要遥功能词did。
但是,在附加疑问句中也可以用used。
例如:   ①He used to smoke,didn't he?
  ②They usedn't to like opera,did they?
  They didn't use to like opera,did they?
  They used not to like opera,did they?
  ③You used to live in Wuhan,usedn't you?
  ④You used to like wine,use(d)n't you?
  三、used to的否定形式的一般问句常有以下两种。
例如:   Didn't you use to live near me?
  Usen't you to live near me?
你过去不住在我附近吗?
  四、 used to指的是过去的习惯遥动作,目的在于与遥形成对照,如:I used to work hard.
是说我过去常常努力工作。
暗含的意义是:我遥不努力工作了。
在表示过去的习惯遥这一点上,与would的意义相同(只不过used to既可用于表示过去的习惯动作,又可用于表示过去的状态。
would只能用于表示过去习惯遥的动作)。
从形态上看used to是个情态动词,其中的to是不定式符号,后面跟动词原形。
例如:   When I was a child,I would get up early.
  People used to(不用would)believe the earth was flat.
过去人们认为地球是平的。
  I used to like swimming.
  When I was a child,I used to(不用would)like swimming.
  我哥哥过去是遥,遥是教师。
  误:My elder brother would be a PLA man.
He is now a teacher.
  正:My elder brother used to be a PLA man.
He is now a teacher.
  五、be(get,become)used to结构在意义上相当于accustomed to习惯于,从形态上看,used是个分词型形容词,to是介词,因此后面只能跟名词、代词或动名词。
例如:   They got used to living in the countryside.
他们已习惯于住在农村。
  I've got used to being a vegetarian.
我已经习惯吃素食。
  He is used to hard work.
他习惯于艰苦工作。
  六、be used to表示习惯于某事的状态,而get used to则表示由不习惯到习惯于这一动态的过程,意思是:(变得)习惯于;开始习惯于。
试比较:   He was used to the cold weather after he lived there for two years.
在那里住两年后,他已习惯了寒冷的天气。
  I think it is a bit difficult for you to get used to the humid weather here.
我想,让你习惯于这里潮湿而炎热的天气有点困难。
  You'll soon get used to living in the country.
很快你就会习惯于住在乡下了。
  七、有时be used to是动词use的被动语态,在这种结构里,to是不定式符号。
例如:   A metal bar was used to force the door open.
用金属棒把门撬开。
  The threshing ground was used to hold a mass meeting.
打谷场曾用于举行群众大会。
  八、be used to与be accustomed to的区别:前者一般用于指自然而然地成为习惯,后者常常用于指通过努力而成为习惯。
试比较:   I am used to teaching English.
我对教英语已习惯了。
  Mrs Smith was not accustomed to leaving home during the winter.
史密斯夫人不习惯冬天出门。
  I am accustomed to taking coffee.
我习惯了喝咖啡。
