2014中考倒计时已经开始了,中考网为同学们整理《2014年中考英语词组辨析:used to do sth/ be used to doing sth》,供广大中考考生参考,希望对大家有帮助! Ⅰ. Used to do sth.“过去常常做某事”(现在不做了),只用于过去时态。如: ① He used to get up early.过去他常早起。(现在已不这样了) ② Her mother used to go shopping on Fridays, but now she does it on Sunday. 她母亲过去常在周五去购物,但现在她周日去了。 Ⅱ. Be used to (doing)sth. “习惯于做某事”,be used 是被动语态结构。可用于现在、过去、将来多种时态。Be可用get, become等代替。如: ① He will be / has been used to getting up early. 他将会/ 已经习惯于早起。 Ⅲ. Be used to do sth. “被用于做某事”, be used 是被动语态结构,其中不定式表目的,可用于多种时态。如: ① Wood is used to make paper.木材用来造纸。 [注]:used to 的否定式有两种:一是:used not to 二是:didn’t use to 如: ① My father used not to smoke. = My father didn’t use to smoke.我爸爸过去不抽烟。 ② They used not to live in the country. = They didn’t use to live in the country. 其疑问式是将used 提前,或添加助动词 did. Ⅳ.would 是情态动词,没有象used to那样,有过去和现在的对比。不能说明是否现在还做不做。 (责任编辑:admin) |
