1、高三英语语法知识点精选英语语法是针对英语语言进行研究后,英语语法系统地总结归纳出来的一系列语言规则。下面就是小编给大家带来的高三英语语法知识点,希望能帮助到大家!高三英语语法知识点1强调句句型1. 陈述句的强调句型:It is/ was + 被强调部分(通常是主语、宾语或状语)+ that/ who(当强调主语且主语指人)+ 其他部分。e.g. It was yesterday that he met Li Ping.2. 一般疑问句的强调句型:同上,只是把is/ was提到it前面。e.g. Was it yesterday that he met Li Ping?3. 特殊疑问句的强调句型
2、:被强调部分(通常是疑问代词或疑问副词)+ is/ was + it + that/ who + 其他部分?e.g. When and where was it that you were born?4. 强调句例句:针对I met Li Ming at the railway station yesterday.句子进行强调。强调主语:It was I that (who) met Li Ming at the railway station yesterday.强调宾语:It was Li Ming that I met at the railway station yesterday.强
3、调地点状语:It was at the railway station that I met Li Ming yesterday.强调时间状语:It was yesterday that I met Li Ming at the railway station.5. 注意:构成强调句的it本身没有词义;强调句中的连接词一般只用that, who,即使在强调时间状语和地点状语时也如此,that, who不可省略;强调句中的时态只用两种,一般现在时和一般过去时。原句谓语动词是一般过去时、过去完成时和过去进行时,用It was ,其余的时态用It is .二、not until 句型的强调句1. 句
4、型为:It is/ was not until + 被强调部分 + that + 其他部分e.g. 普通句:He didn t go to bed until/ till his wife came back.强调句:It was not until his wife came back that he went to bed.2. 注意:此句型只用until,不用till.但如果不是强调句型,till, until可通用;因为句型中It is/ was not 已经是否定句了,that后面的从句要用肯定句,切勿再用否定句了。三、谓语动词的强调1. It is/ was that 结构不能强调
5、谓语,如果需要强调谓语时,用助动词do/ does或did.e.g. Do sit down. 务必请坐。He did write to you last week. 上周他确实给你写了信。Do be careful when you cross the street. 过马路时,务必(千万)要小心啊!2. 注意:此种强调只用do/ does和did,没有别的形式;过去时用did,后面的谓语动词用原形。高三英语语法知识点2as, though, although引导的让步状语从句。注意although位于句首;though位于句首或句中;as位于句中=though。它的词序是把句中强调的形容词
6、、副词、动词或名词放在连词前。参考倒装结构 请注意下列句式的变化:例句1. Although/Though I m young, I already know what career I want to follow.Young as/though I am, I already know what career I want to follow.我虽然年轻,但我已经明白我应该追随什么样的事业。2. Although/Though I respect him very much, I cannot agree with his idea.Much as/though I respect him
7、, I cannot agree with his idea. 虽然我很尊重他,但是我不同意他的观点。3. Although/Though he is a child, he knows a lot of Chinese characters.Child(省略冠词)as/though he is, he knows a lot of Chinese characters. 他虽然还是个孩子,却认识了许多汉字。4. Although he tried, he couldn t solve the problem.Try as he might, he couldn t solve the pro
8、blem. 尽管他努力了,但是他没有解决问题。5. Although it is raining, I m going out for a walk.Raining as it is, I m going out for a walk. 天虽然在下雨,我还是要出去散步。6. Strange as it may seem, nobody was injured in the accident. 这次意外虽然显得不可思议,却没有人受伤。7. Much as I would like to help, I have a lot to do. 虽然我很想帮助你,但是我有很多事要做。8. Object
9、as you may, I will go. 纵使你反对,我也要去。高三英语语法知识点3反意疑问句中的易错点1.在一般疑问句中,无论肯定的问或是否定的问,如果回答为肯定则用yes,反之则用no.特别注意如果出现省略则看下文所暗示的意义。?Are?you?a?new?comer?Yes,?I?came?here?only?yesterday.?Isnt?Tom?a?good?student?Yes,?he?is?excellent.?Dont?you?think?the?composition?good?No,?It?cant?be?any?worse.?注意:在句中,当回答的意思与问句相一致时
10、,则用No,译为“是的”,当回答的意思与问句相反时,则用Yes,译为“不”?2.情态动词must?I?must?leave?now,?mustnt?I?He?must?be?in?the?classroom,?isnt?(表推测)?He?must?have?finished?his?homework,?hasnt?he?(表现在的结果)?He?must?have?finished?his?homework?yesterday?afternoon,didnt?he?(表过去)?当句子中有表示猜测的情态动词时,其反意疑问句的构成不能再用原句中的情态动词,而应根据原句在去掉情态动词的情况下的主谓关系
11、来确定其反问形式。?高三英语语法知识点4名词性从句的几个难点(一)that不可省略的情况1、主语从句,that从句置于句首时;2、当一个句子有两个或多个并列的宾语从句时,引导第二和以后几个从句的that不可省略;3、由it作形式宾语时,that引导的宾语从句中,that不可以省略。(二)wh-ever与no matter wh-的用法区别Wh-ever既可引导名词性从句,又可引导让步状语从句;而no matter wh-只能引导让步状语从句。(三)as if/though, because, why可以引导表语从句注意:because引导的表语从句,主语不能是reason或cause,而且si
12、nce,as不能引导表语从句。(四)that引导的同位语从句与关系代词that引导的定语从句的区别That引导的同位语从句成分是完整的,that在从句中不担当任何成分;that引导的定语从句成分是残缺的,that在从句中充当主语、宾语或表语。高三英语语法知识点5助动词1)协助主要动词构成谓语动词的词叫助动词。被协助的动词称作主要动词。助动词自身没有词义,不可单独使用。例如:He doesnt like English. 他不喜欢英语。(doesnt是助动词,无词义;like是主要动词,有词义)2) 助动词协助主要动词完成以下功用,可以用来:a. 表示时态。例如:He is singing. 他
13、在唱歌。(北京安通学校提供)He has got married. 他已结婚。b. 表示语态。例如:He was sent to England. 他被派往英国。c. 构成疑问句。例如:Do you like college life? 你喜欢大学生活吗?Did you study English before you came here? 你来这儿之前学过英语吗?d. 与否定副词not合用,构成否定句。例如:I dont like him. 我不喜欢他。e. 加强语气。例如:Do come to the party tomorrow evening. 明天晚上一定来参加晚会。He did know that. 他的确知道那件事。3) 最常用的助动词有:be, have, do, shall, will, should, would等。3 助动词be的用法1) be +现在分词,构成进行时态。例如:They are having a meeting. 他们正在开会。English is becoming more and more important. 英语现在越来越重要。(北京安通学校提供)2) be + 过去分词,构成被动语态。例如:The window was broken by Tom. 窗户是汤姆打碎的。高三英语语法知识点精选五篇分享第 7 页 共 7 页
