高考英语省略知识
考点一、状语从句中的省略
(1) 当主句主语与从句主语相同(或从句主语为it)，并且从句谓语中含be动词，常将从句主语和be动词省略，构成省略形式。(2) as / than引导比较状语从句时，从句通常使用省略形式。如：He earns less than his wife (does).【考例】The climate here is quite pleasant, the temperature rarely, ____, reaching 30°C in summer.A. if notB. if everC. if anyD. if so解析：B。当从句中的主语是it，谓语动词中又含有系动词be时，可以把it和系动词be一起省略。if ever与rarely连用，意为“极少”。
考点二、动词不定式的省略
【考例1】 Let those in need ____ that we will go all out to help them.A. to understandB. understand C. understanding D. understood 解析：B。let sb do sth使役动词后面的动词不定式符号to省略。 【考例2】 The driver wanted to park his car near the roadside but was asked by the police _____. A. not to do B. not to C. not do D. do not解析：B。“在路边停车”这一动作前面已经提到，所以后面应省略以使句子简洁。
考点三、使用替代词so / not
英语中常用so / not等来代替省略的肯定内容或否定内容，多跟在I’m afraid / I hope / I think / I guess / I believe / I expect / I suppose等开头的答语中，条件状语从句中也有类似的用法。如：if so / if not句中。【考例1】—You could always put the decision off a little bit longer.—____ If I leave it much longer I might miss my chance. A. That’s reasonable advice. B. Isn’t it a good idea?C. Do you think so? D. I can’t agree more. 解析：C。第二个人不是肯定第一个人的意见，用Do you think so? 先进行反问，然后给出自己的观点。
考点四、情景交际中的省略
在情景对话中，常常省略大家都知道的内容或不会引起歧义的部分，只保留主干部分或关键词。【考例】 —Mary’s been offered a job in a university, but she doesn’t want to take it. —____? It’s a very good chance. A. Guess what B. So what C. Who cares D. But why 解析：D。But why(但是为什么)是But why(doesn’t she want to take it)?的省略。
