高考英语新题型语法填空。

本题型分两种情况：一种为已给单词提示，一种为不给单词提示。

语法填空的做题技巧总结。

此类题可以考查学生对单词形式变化的掌握程度。

单词形式变化主要有两种，一是词的形、数、式的变化，一是词的派生变化。

在判断出词的变化之后还应该进一步审题，看是否需要使用复合的变化形式，这一点是很重要的。

名词的形式变化主要有单数、复数、所有格的变化。

例：There are many students living at school，the (child) houses are all far from school．由students一词可以判断出横线处应填复数，且作为houses的定语，所以应用其所有格形式，故答案为child的复合变化形式—复数的所有格children’s。

技巧二：动词形式变化。

动词的形式变化比较多，有谓语的变化(时态、语态、语气)，有非谓语的变化(不定式、动名词、现在分词、过去分词)。

例：A talk (give) tomorrow is written by Professor Zhang.句中的is written是整句的谓语，所以横线所在的动词应当用作非谓语。

从tomorrow 可以看出，报告是“将来”作的，故用不定式；且报告是give动作的承受者，故可以判断出横线所在处用give的不定式被动式——to be given。

技巧三：代词形式变化。

代词形式变化通常是与人称变化有关的三大类五小类，即人称代词(主格和宾格)、物主代词(形容词性和名词性)、反身代词。

另外还有几个不定代词的形式变化，如no one／none、other／another等。

例：The king decided to see the painter by (he).由介词by可以看出，横线处应填反身代词himself。

技巧四：形容词、副词比较级变化。

英语中大部分形容词和表方式的副词都有原级、比较级和最高级的变化。

名词性从句包括主语从句、宾语从句、表语从句和同位语从句。

名词性从句是一种具有名词功能的非独立分句。

具体用法见下表：主语从句大多数主语从句都可以用it作形式主语而把主语从句置于句尾。

(what引导的主语从句表示“……的东西”时，一般不用it作形式主语；whatever, whoever, whichever一般也不用it作形式主语。

)►It makes no difference where we shall have the meeting.我们在哪开会无所谓。

【注意】(1)常见的it替代that引导的主语从句的句式主要有以下几种：①It＋系动词＋形容词(necessary/right/likely/important/certain...)＋that从句②It＋be＋名词(短语)(a pity/a shame/good news/a fact/an honour...)＋that从句③It＋be＋过去分词(said/told/heard/reported/decided/suggested...)＋that从句④It＋特殊动词(seem/appear/happen/matter)＋that从句(2)在“It is necessary/important/natural...＋that从句”的结构中，从句谓语常用“(should ＋)动词原形”。

宾语从句1．动词find, feel, think, consider, make, believe等后有that引导的宾语从句作宾语补足语时，则常用it作形式宾语而将that宾语从句后置。

►I think it necessary that we take plenty of boiled water every day.我认为每天摄入足量的白开水很有必要。

2．有些动词(短语)不能直接跟宾语从句，需要借助形式宾语it。

常见的有hate, enjoy, like, dislike, love, appreciate, see to等。

名词性从句一、概念：在句中起名词作用的句子称名词性从句。

名词性从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等,因此根据它在句中不同的语法功能,名词性从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。

1、引导名词性从句的连接词可分为三类：连接词：that, whether ,if (不充当从句的任何成分)连接代词：what, whatever, who, whoever, whom, whose, which连接副词：when, where, how, why2、不可省略的连词：①介词后的连词②引导主语从句和同位语从句的连词不可省略。

例如：That she was chosen made us very happy. 她被选上了,我们很高兴。

We heard the news that our team had won. 我们听到消息说我们队赢了。

注：比较：whether与if均为"是否"的意思。

但在下列情况下,whether不能被if 取代：①whether引导主语从句并在句首②引导表语从句③whether 从句作介词宾语④从句后有"or not"大部分连接词引导的主语从句都可以置于句末,用it充当形式主语。

例如：It is not important who will go. 谁去,这不重要。

It is still unknown which team will win the match. 到底谁赢呢,形势尚不明朗。

3、名词性that-从句①由从属连词that引导的从句叫做名词性that-从句。

That只起连接主句和从句的作用,在从句中不担任任何成分,本身也没有词义。

名词性that-从句在句中能充当主语、宾语、表语、同位语和形容词宾语。

例如：主语：That he is still alive is sheer luck.他还活着全靠运气。

从句从句按其在主句中的句法功能可分为三类:即名词性从句、形容词性从句(即定语从句)和副词性从句(即状语从句)。

引导从句的词称作关联句。

一、名词性从句引导这些名词性从句的关联词包括:从属连词：that, if, whether;连接代词：who,whoever,whom,whomever,which,whichever,what,whatever,wh ose;连接副词where, when, why, how。

其中, 从属连词只起连接作用, 在从句中不充当任何句法成分,而连接代词和连接副词既起连接作用, 在从句中又充当一定的成分.不可省略的连词：1. 介词后的连词2. 引导主语从句和同位语从句的连词不可省略。

That she was chosen made us very happy.We heard the news that our team had won.比较：whether与if 均为"是否"的意思。

但在下列情况下，whether 不能被if 取代：1. whether引导主语从句并在句首2. 引导表语从句3. whether从句作介词宾语4. 从句后有"or not"Whether he will come is not clear.The fact is that he didn't go to the dinner party.I don't know if he will attend the meeting.1. 在含有主语从句的复合句中, 为保持句子平衡, 常用it作形式主语,而将真正的主语从句置于句末. That-从句作主语通常用it作先行词，而将that-从句置于句末，例如：It is quite clear that the whole project is doomed to failure.很清楚，整个计划注定要失败。

高中英语所有从句（上）一、名词性从句精讲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）。

在句子中起名词作用的句子叫名词从句(Noun Clauses）。

名词从句的功能相当于名词词组,它在复合句中能担任主语、宾语、表语、同位语等，因此根据它在句中不同的语法功能，名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。

引导名词性从句的连接词可分为三类：（1）从属连接：that, whether, if（不充当从句的任何成分）（2）连接代词：what, whatever, who, whoever, whom, whose, which.（3）连接副词：when, where, how, why主语从句做句子主语的从句叫主语从句。

主语从句通常由从属连词that，whether，if和连接代词what，who，which，whatever，whoever以及连接副词how，when，where，why等词引导。

that在句中无词义，只起连接作用；连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用，在从句中充当从句的成分。

1. that引导That he is still alive is a wonder. 他还活着，真是奇迹。

That we shall be late is certain. 我们要晚了，这是确定无疑的。

2. whether引导Whether it will do us harm remains to be seen. 是否对我们有害还要看一看。

Whether they would support us was a problem. 他们是否会支持我们还是一个问题。

定语从句中作状语时，也要用关系副词where引导。
①We will put off the picnic in the park until next week， when the weather may be better.
我们将把在公园的野餐推迟到下周，届时天气可能会更好。 ②Students should involve themselves in community activities where
答案与解析：where 考查定语从句。 分析句子结构可知，空格处引导定语从 句，先行词为campaign，空格处在从句中作地点状语。故填where。

主语从句讲解及练习主语从句一、概述：在句子中起名词作用的各种从句统称为名词性从句。

根据它们在句中的语法作用，这类从句又可分为主语从句、同位语从句、表语从句和宾语从句。

二.主语从句主要有三类：（1）由连词that引导的主语从句:引导词that无含义,在句中不做成分,不可以省。

例如：That you will win the medal seems unlikely.你想获得奖牌看起来是不可能的。

That you are so indifferent bothers me.你如此冷淡使我很烦恼。

That she survived the accident is a miracle.她在事故中幸免于难简直是奇迹。

（2）用连词whether 引导的主语从句:whether有含义(是否),在句中不做成分,不可以省。

例如：Whether she is coming or not doesn’t matter too much.她来不来都无关紧要。

（3）用连接代词引导的主语从句(在由连接代词who, whose, whom, which, what, whoever, whomever, whichever, whatever引导的名词性从句中，其连接代词在句中起名词性作用，担当一定成分).例如：What you need is more practice.你所需要的是更多的训练。

What I want to know is this. 我想知道的就是这事。

Whatever we do is to serve the people.我们无论做什么都是为人民服务。

（4）连接副词when, where, why, how引导的名词性从句(其连接副词有含义,在句中作状语。

)eg:Where we should leave it is a problem.When they will come hasn’t been made pubic.他们什么时候来还不知道。

2021届高中英语新高考语法基础版一轮复习讲义（一）三大从句时态知识点整理总结（含练习）从句的时态是困扰很多同学的问题，尤其是想到六种从句和多达十几种时态的相互碰撞，就头疼不想看。

Part 1: 宾语从句的时态三定律定律一主过从过：当主句时态为过去时，从句一律要变为过去时态。

定律二主现/将|从不限：当主句为现在时或一般将来时，从句时态据实而定。

定律三从真理、主不限：从句为客观真理，用一般现在时，主句不限时态。

Part 2：状语从句的时态二连击定律四主将从现：主句为一般将来时，从句用一般现在时。

连接词一般为：when/as soon as/not...until/before等。

定律五一个过去用过去，两个过去用过完。

如果以现在为参照，以动作发生时间划分，最近的过去为G1，其次是G2。

主从都为过去，且二者有明显时间差，则G1为一般过去式，G2为过去完成时。

主从都为过去，二者同时发生或无明显时间差，均为G1，均用一般过去式。

Part 3：名词性从句的时态1. 当主句的谓语动词是过去式时，宾语从句若不是一个客观事实或真理，其谓语动词也必须用某种过去时态。

如：She said that she didn't want to know.她说她不想知道。

I asked her whether she would agree.我问她是否会同意2. when, if 这两个词既可引导名词性从句，也可引导状语从句。

当它们引导名词性从句且表示将来意义时，要直接使用将来时态;但当它们引导状语从句且表示将来意义时，则必须用一般现在时表示将来意义。

如：I don’t know when he will come, but when he comes, I’ll call you.我不知道他什么时候，但当他来的时候，我会打电话给你。

句中第一个when 引导的是宾语从句，故用将来时态表示将来意义;第二个when 引导的是时间状语从句，故用一般现在时表示将来意义。

板块三 句法集释三大从句从句可分为定语从句、状语从句和名词性从句，它们是中学阶段的重要语法项目，其引导词的选择既是高考必考点，又是同学们学习与复习的一大难点。

定语从句是形容词性从句，相当于形容词的用法，其功能是修饰先行词，对其性质、特征进行描述，先行词在定语从句中一般充当主语、宾语、表语、定语或状语等。

状语从句是副词性从句，相当于副词的用法，其功能是在复合句中作状语。

根据状语从句的含义，状语从句一般可以充当时间、地点、原因、条件、目的、结果、让步、方式和比较等从句。

名词性从句的功能相当于名词词组，一般在句子中充当主语、表语、宾语或同位语。

1．(2013·江苏高考)The president of the World Bank says he has a passion for China, ________ he remembers starting as early as his childhood.A ．whereB ．whichC ．whatD ．when解析：选B 考查定语从句。

分析句子结构可知，“________ he remembers starting as early as his childhood”为定语从句，先行词是passion ，且空处在从句中作宾语，因此选which 。

2．(2013·安徽高考)Mo Yan was awarded the Nobel Prize for Literature in 2012,________ made one of the Chinese people's long­held dreams come true.A．it B．thatC．what D．which解析：选D 考查定语从句。

句意：莫言获得了2012年诺贝尔文学奖，这使得中国人民很久以来的一个梦想得以实现。

此处为非限制性定语从句，修饰整个主句。

高中英语语法考点纵览第十二章三大从句一、概述从句依托于主句而存在，隶属于主句。

从句作为一种重要的句法形式在英语法中起着举足轻重的作用。

本章从从句的分类（三大从句：名词性从句、形容词性从句（定语从句）和副词性从句（状语从句））入手，详尽介绍了每种从句的具体用法，包括定义、作用、关联词的用法及相关比较。

最后，对本章内容进行了全面总结，提炼精华。

把从句上升到一定的理论高度，运用从句去剖析一些重要语言现象的本质，搭建知识点之间的联系。

本章内容较整，在学好每种从句的基础之上，结合知识网形成完整的知识体系，充分运用从句解决实际的语言问题。

二、从句的分类根据从句在主从复合句中的作用（或相当某个词在句中的作用可将从句分为：名词性从句、形容词性从句（定语从句）、副词性从句（状语从句）。

下面将全面阐述各类从句的具体用法。

三、名词性从句1、定义及分类在句子中充当名词所能充当的句法成分的从句称之为名词性从句。

名词性从句包括：主语从句、宾语从句、表语从句和同位语从句。

所有的名词性从句都用陈述语序。

2、作用名词性从句在句子中充当名词所能充当的句法成分，每个名词性从句的名称都是由其所在主从复合句中所充当的句子成分所决定的。

主语从句充当主语的作用，相应地宾语从句充当宾语、表语从句充当表语、同位语从句充当同位语。

3、引导名词性从句的关联词主从复合句中主句和从句之间要有连词予以连接，引导名词性从句的关联词主要有以下几种。

①连接词that、whether和ifA、连词that无实义，在一定情况下可以省略。

whether和if有具体意义表示“是否”，不能省略。

that 和whether可以引导所有的名词性从句；if只能引导宾语从句或不放在句首的主语从句。

（即用先行it作形式主语）B、whether引导的名词性从句可以放在复合句的句首，而if引导的名词性从句只能放在主句谓语动词后面。

引导宾语从句时，whether和if一般情况下可以互换。
