请教used to do和be used to doing的区别

如题所述

  1.意思不同。
  used to do:过去常常,过去曾经;过去常常做某事。
  be used to doing:习惯于做某事。
  2.构成不同。
  used to是动词短语。而be used to doing是系表结构。
  3.否定不同。
  used to用来帮助提问和否定的词是used或者用助动词did。如:
  He usedn't to play computer games.可以是He didn't use to play computer games..
  他过去不常打电脑游戏。
  Usedhe use to play computer games?=Did he use to play computer games?
  他过去不常打电脑游戏吗?
  He isn't used to talking in English.
  他不习惯于用英语交谈。
  Is he used to talking in English?
  他习惯于用英语交谈吗?
  4.后面接的词不同。
  used to后面接动词原形;be used to后面接动名词或是名词。
  例如:
  "I used to do this rather regularly, particularly with shoplifters, " the judge said.
  “我以前经常这么判决,特别是对那些商店扒手,”法官说。
  You can make these bets not just once or twice a day, as people used to do, butonce or twice a millisecond.

  If you're constantly talking about how you used to do things at your last job or whenthe old boss was in charge, people will wonder why you stick around.
  如果你总说你以前是怎么工作的,或者上一任老板在的时候是怎样的,别人会想不通,你为什么一边抱怨,一边还赖着不走。

be/get used to doing sth.表示习惯于做某事或习惯于某事,to是介词,后面要跟名词、代词或动名词.而used to do sth.则表示过去常常,to后跟原形动词.如:Now he is used to getting up early.现在他已经习惯早起了.He used to get up early.过去他经常早起.(意味着如今他不再早起了.)You'll soon get/be used to hard work.你会很快习惯于艰苦的工作的.本回答被提问者采纳
