近五年高考英语语法填空从句总结 从句一直以来都是高考英语语法填空题的必考点。从句是相对于主句而言的，即它是从属 于某一个主句，而不能单独作一个句子。在英语中，主要有三大从句，即名词性从句(包括主语从句，宾语从句，表语从句，同位语从句)、形容词性从句(即定语从句)、副词性从句 (即状语从句,包括时间、条件、结果、目的、原因、让步、地点、方式等)。 高考中从句知识点考查最多的是定语从句。我们将近五年高考题中语法填空题涉及的从句 进行总结，希望可以为英语老师们帮助学生解答这一类题型提供助力。 2019年 全国I卷 While they are rare north of 88°,there is evidence61 they range all the way across the Arctic, and as far south as James Bay in Canada. 全国 II卷 Now Irene Astbury works from9 am to 5 pm daily at the pet shop in Maccles field,62she opened with her late husband Les. 全国 III卷 They were well trained by their masters64 had great experience with caring for these animals. 浙江卷 On the edge of the jacket, there is a piece of cloth 58 gives off light in the dark. 2018年 全国I卷

高三英语知识点总结归纳5篇分享 学习高三英语知识点的时候需要讲究方法和技巧，更要学会对高三英语知识点进行归纳整理。 高三英语知识点1 look at a book? 1. 表示阅读性地“看书”(即读书)，一般要用动词read。如： Don’t read such books. 不要读那样的书。 He is reading a book on Shakespeare. 他在看一本关于莎士比亚的书。 但是，在许多情况下，“看书”只需用read 就够了(尤其是泛泛地表示“看书”时)，无需后接book作宾语。如： In the evening I usually read. 晚上我常常看书。 This light is too poor to read by. 这光线太暗不能看书。 I read much less now than I did at school. 我现在看书远比我上学时少。 2. 若不是表示阅读性地“看书”，而只是大概地看一看，比如看看书的封面、定价、内容提要等，或者回答问题时看看书的某些章节或字句等，或者是考试时悼词楸镜龋此时都不宜用动词read, 可用look at, see 等。如： Can I look at those books? 我可以看看那些书吗?
Jim demanded to see my books. 吉姆要求看看我的书。 Please answer my questions without looking at your books. 请不看书回答我的问题。 Students must not look at their books during examinations. 学生考试不准舞弊。 高三英语知识点2 虚拟条件句 条件状语从句是非真实情况，在这种情况下要用虚拟语气。 l-条件从句与现在事实不一致，句型为：If+主语十过去时，tiag+should (could，would，或might)+动词原形，例如：If l were you，1 would study hard. 2.条件从句与过去事实不一致，句型为：If+主语+had+过去分词，主语+should(could, would，或might)+have+过去分词，例如：If I had not studied hard.1would have failed in the exam last term 3.条件从句与将来事实不一致，句型为：lf+主语+should/were to+do，主语+should( could.)+原形do，例如：If l were to go to the moon one day,I could see itwith my own eyes. 注意： 1.If条件句中绝对不可出现“would”。 2-根据句中的时间状语，有时可能出现“混合虚拟”的情况，即主
【宾语从句】 在英语中，有简单句(只含一个谓语动词)、并列句(用连词连接，含不止一个谓语动词)和复合句(含从句)。本节课我们复习复合句里面的宾语从句 ．．．．。 如：She knows that he will come back soon. I’m afraid that I can’t go to your party. 1.宾语从句的【引导词】 宾语从句的引导词分三种。 ●(1) 如果从句是陈述句，引导词用that.（that在口语中常省略） 主句：He says... 从句：He is tired of playing computer games. → He says that he is tired of playing computer games. ●(2) 如果从句是一般疑问句，引导词用if/whether，表示“是否”。 主句：I don’t know… 从句：Does Tom likes fish? → I don’t know if / whether Tom likes fish. 【注意】① whether引导的从句常与or not连用，而if不能； ②宾语从句可简化为whether to do的搭配，而没有if to do这种搭配. 如：Could you tell me whether I should finish my homework today or not? Could you tell me whether to finish my homework today? 【拓展】if有两个意思： 1. 表示“是否”，引导的是宾语从句。动词的时态视情况而定。 2. 表示“如果”，引导的是条件状语从句，时态用一般现在时表示将来（遵循“主将从现”规则）。 经典例题：--Do you know if Tom ____________(go) hiking with us ? --I’m not sure. But i f he ____________(go), I will take many photos with him . ●(3) 如果从句是特殊疑问句，直接用该疑问词来引导。 主句：Do you know… 从句：what does he want to buy? → Do you know what he wants to buy? 你知道他想要买什么吗？ 2. 宾语从句的【时态】 ■(1) 当主句是一般现在时，从句根据情况使用任何时态 如：She wants to know if I have finished my homework. 她想知道我是否已经完成了我的作业。 Do you know when he will be back? 你知道他将会什么时候回来？ ■(2) 当主句是一般过去时，从句应使用过去的某时态 如：He said that she was singing. 他说她正在唱歌。 She wanted to know if I had finished my homework. 她想知道我是否已经完成了作业。 Did you know when he would come back? 你知道他将会什么时候回来？ 【注意】格言和客观真理总是用一般现在时。 如：She told me yesterday (that) the earth travels around the sun.

高三英语语法教案：从句 分类说明 英语中从句分为名词性从句、定语从句及状语从句。从句的语序必须是陈述语序。一．名词性从句：名词性从句分为主语从旬、宾语从句、表语从旬及同位语从句。引导词：连接代词what，who，whom，whose，which，wh- ever；连接副词when，where，why，how，that，if，whether。 what，who，whom，whose，which，when，where，why，how，if，whether等引导的从句往往含有质疑或疑问；而that引导的从句表示一种事实或陈述的内容。1．主语从句：在主语从句中，that不能省略，若从句在句首，从句不能用if引导。为了避免由于主语从句过长而引起的头重脚轻，常用It作形式主语，而将主语从句移到句子末尾。 2．宾语从句：从句的引导词that可省略，从句的时态必须与主句的时态保持一致。3．表语从句：从句中的引导词that一般不能省略，但当主句中含有动词do的各种形式时，that可以省略。 4．同位语从句：引导词that不能省略，同位语从句与前面的名词之间是表述或说明的关系，而不存在修饰关系。因此，在名词与从句之间若加be动词，句子的意思成立。 二．定语从句：定语从句分为限制性定语从句和非限制性定语从句。 1．限制性定语从句：对先行词进行限制或修饰。 先行词：名词或代词 引导词：关系代词which，that，who，whose，whom，as；关系副词when，where，how，why 2．非限制性定语从句：对先行词进行补充或说明。 先行词：名词、代词或整个句子
引导词：关系代词which，who，whose，whom，as；关系副词when，where 3．注意事项： (1)引导词的选用：引导词既可引导两个句子，又可在从句中充当一定的成分。 在限制性定语从句中，which只能指事、物；that，whose既可指物也可指人：who，whom只能指人；as一般与such，the same，SO连用；but的先行词一般为否定词或否定词所修饰的词。when，where，how，why分别指时间、地点、方式及原因状语。主、从句之间不用逗号分开。 在非限制性定语从句中，which只能指事、物或整个句子的内容；whose既可指物也两指人；who，whom只能指人；as只用来指整个句子的内容。主、从句之间一般用逗号隔开。 在非限制性定语从句中，which，as两个单词都可用来指整个句子的内容，但它们的区别在于： A位置：which所引导的定语从句只能在主句之后；而as所引导的句子既可在主句之后，也可在主句之前。 B意义：which所引导的从句既可为积极的意义也可为消极的意义；as所引导的从句一般只能为积极的意义。此外，which一般指主句本身；而as还用来表示“对照”的意义，意思为“就像……一样”。 (2)从句中的谓语形式：一般说来，从句的谓语形式由先行词确定，但当先行词为one of +n．(p1)且one前面有形容词修饰时，从句的谓语动词的形式由one确定。 (3)定语从句与同位语从句、状语从句、强调句的区别。 三．状语从句：状语从句分为时间、地点、原因、条件、让步、结果、目的、方式及比较状语从句。 1．特征： (1)时间状语从句：连接词when，while，as，before，after，as soon as，till，until, not…until，the moment，immediately，the first／second…last time，instantly．h ardly…when, seldom…when．no sooner…than
高考英语定语从句、名词性从句、状语从句综合练习 一定语从句 1.定义：在复合句中，修饰名词或代词的从句为定语从句，如： The novels that were written by Lu Xun were not easy to understand. 2.定语从句的构成要素 （1）先行词： （2）关系词： （3）从句： 3.定语从句的关系词 that which （1）关系代词who whom whose as when （2）关系副词where why 4.关系词的句法功能： （1）关系代词在定语从句中作______________，关系副词在定语从句中作_______________，关系代词作宾语时可以省略； （2）关系副词在定语从句中作______________。 5.定语从句解题方法 找准先行词，将先行词带入定语从句，使定语从句成为一个完整的句子，再分析从句的句子成分。若从句缺主语或宾语选用_____________________，若从句却状语，选用_____________________。 二、名词性从句 1.名词性从句分类 （1）主语从句 （2）宾语从句 （3）表语从句 （4）同位语从句 2.名词性从句的语序 名词性从句使用________________语序 3.名词性从句的引导词 连接词：that, whether, if 名从引导词连接代词：what, which, who, whom, whose, whatever, whichever, whomever, whomever 连接副词：when, where, why, how, whenever, wherever, however 4.名词性从句引导词的句法功能

高考英语主语从句 定义：用作主语的从句叫主语从句，它是名词性从句之一。主语从句的时态：不受主句的时态影响和限制。引导主语从句的连接词有： 从属连词: that, whether； 连接代词: who (whoever), whom, whose, what (whatever)和which (whichever)； 连接副词: when, where, how和why。 连接词： 1. 从属连词：that，whether 1）that引导主语从句只起引导作用，在主语从句中不充当任何成分，that本身无实际意义，但不能省略。2）whether意为“是否”，放在句首句末皆可。由whether引导的名词从句做主语，表语，介词宾语，同位语时！不可用if代替。 a.That price will go up is certain. b. Whether they would support us was a problem. 他们是否会支持我们还是一个问题。 2. 连接代词who ，what ，which, whatever, whichever, whoever (Who, whom, which, what可以和ever构成合成词，和what一样引导从句，ever起到强调作用。此类主语从句不能用形式主语it引导，它们在句子中担任成分，不能省略，语序为陈述语序，既有疑问含义,又起连接作用,同时在从句中充当各种成分。 Which side will win is not clear. Whoever breaks the law will be punished. Whatever he did is right. Who killed the scientist remains a question. 1）What和that引导的主语从句的区别：that 只起引导作用，不充当任何成分，没有意思。What 不仅起引导作用，还要充当一定成分(主语、宾语或表语)，意思是：“什么”。 What we need is money. That he will come is certain. 2）whatever / whoever的用法（~ever=no matter ~---让步状语从句中） whatever / whoever可以引导主语从句,并在句中作主语、宾语、表语等,不含疑问意义。whatever相当于anything that; whoever 相当于anyone who。例如: Whoever(Anyone who) wants to enter into this school must take the exam. Whatever(Anything that) she did was right. 3. 连接副词when，where，how，why等。既有疑问含义,又起连接作用,同时在从句中充当各种成分。How this happened is not clear to anyone. When he will be back depends on the weather. When we’ll start tomorrow will be told soon. Where the test will be given is not yet decided. 4. 主语从句后置：为了避免主语冗长,句子头重脚轻,经常用it 作形式主语,主语从句放在后面作真正的主语. 例: That we shall be late is certain. -- It’s certain that we shall be late. 1）用it 作形式主语的结构 A. It + be + 形容词+ that 从句 (obvious, true, surprising, good, wonderful, funny, possible, likely, certain, probable, etc.) 如：It is certain that she will do well in her exam. B. It + be + 名词词组+ that 从句(an honour, a fact, a pity, etc）如： It is a pity/shame that... 遗憾的是…… It is a surprise that…令人惊奇的是… It is a fact that… …是事实It is common knowledge that… …是常识 It’s a pity that we can’t go. C. It + be + 过去分词+ that 从句(said, reported, thought, expected, decided, announced, etc。）如：It is said that Mr. Green has arrived in Beijing. D. It + 不及物动词或短语+ that 从句( seem，happen, doesn’t matter ,turn out）。如： It happened that I was out that day. It doesn’t matter whether she will come or not. 2) 对于以连接代词(副词)引导的主语从句,可以使用形式主语代主语从句,也可直接在句首使用主语从
