高考英语省略知识点
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 if if if 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 to understand understanding 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 not to do not to not do 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 —____ If I leave it much longer I might miss my That’s reasonable Isn’t it a good Do you think so? I can’t agree 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’s a very good Guess what So what Who cares 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。
