考点5】语法考点归纳5(定语从句、名词性从句)
【考点五】语法考点归纳5（定语从句、名词性从句） 定语从句考点归纳 1．高考对定语从句的考查集中体现在关系词的选择上，包括关系代词和关系副词。关系代词只有6个，即：that，which，who，whom，whose，as，关系副词只有3个，即：when，where，why。 2．选择关系代词和关系副词的方法：由于关系词既有连接作用又有替代作用和成分作用（引导定语从句并在从句中替代先行项/词而且还充当一定的成分），所以在选择关系词时有一个很简单的方法。把先行项/词还原到从句中，看看该用什么关系词来替代。例如： I visited a scientist ______ name is known all over the country. 把先行词a scientist还原到从句中就是：the scientist’s name is known all over the country 可见从句中缺定语，这里该填whose。又如：The school _____ I studied for only two years was three kilometers away. 把先行词the school还原到从句中就构成这样一个简单句：I studied for two years in the school. “in the school”是一个表示地点的介词短语，在从句中作状语，要用where（=in which）来替代。 3．注意关系代词as和which引导非限定性定语从句的区别：as引导的非限定性定语从句可以置于句首，而which 引导的非限定性定语从句只能位于句中或句尾。 4．注意掌握只用关系代替that、只用关系代词which的常见的几种情况，以及“介词+关系代词”引导的定语从句。 考点精析 1.关系代词引导的定语从句 关系代词所代替的先行词是人或物的名词或代词, 并在句中充当主语, 宾语, 定语等成分. 关系代词在定语从句中作主语时, 从句谓语动词的人称和数要和先行词保持一致. (1)Who, whom, that这些词代替的先行词是人的名词或代词, 在从句中所起的作用如下: Is he the man who/that wants to see you 他就是你想见的人吗(who/that在从句中作主语) Hs is the man whom/that I saw yesterday. 他就是我昨天见的那个人.(whom/that在从句中作宾语) (2)whose用来指人或物, 只用作定语, 若指物, 它还可以同of which.互换. 例如: They rushed over to help the man shoes car had broken down. 那人的车坏了, 大家都跑过去帮忙 Please pass me the book whose (of which) cover is green. 请递给我那本绿皮的. (3)Which, that它们所代替的先行词是指代事物的名词或代词, 在从句中可作主语, 宾语等. 例如: A prosperity which/that had never been seen before appears in the countryside. 农村出现了前所未有的繁荣. (Which/that在句中作宾语) The package (which/that) you are carrying is about to come unwrapped. 你拿的包快散了(which/that在句中作宾语) 2.关系副词引导的定语从句 关系副词可代替的先行词是时间. 地点或理由的名词, 在从句中作状语. (1). When, there, why 关系副词when, where, why的含义相当于“介词+which”结构, 因此常常和“介词+which”结构交替使用. 例如: There are occasions when (on which) one must yield.
赖氏经典英语语法—名词性从句
名词性从句 名词性从句包括宾语从句、主语从句、表语从句、同位语从句。 名词性从句一共有三种：1）that从句；2）whether从句；3）疑问词所引导的从句。 分项说明如下： 1）that从句 任何一个主语起首的陈述句前面冠以that，即成that从句。 He enjoys dancing. That he enjoys dancing. 2）whether从句 由可用yes/no回答的问句，即一般疑问句变化而成。 a) 问句有be动词时：Is he happy? Whether he is happy. b) 问句有一般助动词（can, will, may, should, ought to, must, have）时： Can he do it? Whether he can do it c) 问句有do, does, did等助动词时：主语与助动词还原，再将do, does, did去掉，后面的动词依人称和时态变化。 Did he come? Whether he came 3）疑问词所引导的从句 由疑问词（when, what, how, where, why）等引导的问句，即特殊疑问词，变化而成。 a) 问句有be动词时：What is he doing? What he is doing. b) 问句有一般助动词（can, will, may, should, ought to, must, have）时： 主语与助动词还原，前面保留疑问词。Where can he find it?

Who came here. 名词性从句的功能： 1）作主语 Where he lives is still in doubt. 2）作及物动词的宾语 I know that he will go abroad in the near future. 3）作介词的宾语 a)此时仅能用whether从句或疑问词引导的名词性从句作宾语。That从句不可作介词的宾语。 I am worried about whether he can do it. prep. o. I am curious about how he’ll cope with the problem.
名词性从句知识点总结
名词性从句知识点总结 在句子中起名词作用的句子叫名词性从句(Noun Clauses）。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。 一．主语从句 主语从句是在复合句中充当主语的从句，通常放在主句谓语动词之前或由形式主语it代替，而本身放在句子末尾。 1. It 作形式主语和it引导强调句的比较 It 作形式主语代替主语从句，主要是为了平衡句子结构，主语从句的连接词没有变化。而it引导的强调句则是对句子某一部分进行强调，无论强调的是什么成分，都可用连词that。被强调部分指人时也可用who/whom。例如： a) It is a pity that you didn’t go to see the film. 你不去看那场电影真可惜。 b) It doesn’t interest me whether you succeed or not.我对你成功与否不感兴趣。 c) It is in the morning that the murder took place.谋杀案是在早上发生的。（强调句型） d) It is John that broke the window.是John打碎的窗户。（强调句型） 2. 用it 作形式主语的结构 (1) It is ＋名词＋从句 It is a fact that …事实是… It is an honor that …非常荣幸 It is common knowledge that …是常识 (2) It is ＋形容词＋从句 It is natural that…很自然… It is strange that…奇怪的是… (3) It is ＋不及物动词＋从句 It seems that…似乎… It happened that…碰巧… It appears that…似乎… (4) It ＋过去分词＋从句 It is reported that…据报道… It has been proved that…已证实… It is said that…据说… 3. 主语从句不可位于句首的五种情况： （1）if 引导的主语从句不可居于复合句句首。 （2）It is said /reported…结构中的主语从句不可提前。例如： 正确表达：It is said that President Jiang will visit our school next week. 错误表达：That President Jiang will visit our school next week is said. （3）It happens/occurs…结构中的主语从句不可提前。例如： 正确表达：It occurred to him that he failed in the examination. 错误表达：That he failed in the examination occurred to him. （4）It doesn’t matter how/whether …结构中的主语从句不可提前。例如： 正确表达：It doesn’t matter whether he is wrong or not.
高考英语语法复习三：名词性从句
高考英语语法复习三:名词性从句 名词性从句相当于名词,可分别作主句的主语、表语、宾语和同位语。因此,名词性从句可分为主语从句、表语从句、宾语从句和同位从句。 (一引导名词性从句的连接词 1、连接代词:who, whose, whom, what, which。有词义,在从句中担任成分,如主语、表语、宾语、或定语等。 2、连接副词:when, where, why, how。有词义,在从句中担任成分,作状语。 3、连接词:that, whether, if, as if。that 无词义,在从句中不担任成分,有时可省略; if (whether, as if虽有词义,但在从句中不担任成分。 注意:连接代词与连接副词在句中不再是疑问句,因而从句中谓语不用疑问式。连接代词与连接副词在从句充当句子成分,连接词whether 和if(是否,as if(好象在从句中不充当句子成分,只起连接作用。根据句义,如果连接代词与连接副词,whether、if 和as if 都用不上时,才用that作连接词(that本身无任何含义。 (二主语从句 1、主语从句在复合句作主语。 e.g. Who will go is not important. 2、用it作形式主语,主语从句放在句末。 e.g. It doesn't matter so much whether you will come or not. 3、that引导主语从句时,不能省略。 e.g. That he suddenly fell ill last week made us surprised. (三表语从句 1、表语从句在复合句中作表语,位于系动词之后。 e.g. The question was who could go there. 2、引导表语从句的连接词that有时可省去。 e.g. My idea is (that we can get more comrades to help in the work. (四宾语从句 1、宾语从句在复合句中作宾语。引导宾语从句的连词that一般可省略。 e.g. I hope (that everything is all right. 2、介词之后的宾语从句,不可用which或if连接,要分别用what或whether。 e.g. I'm interested in whether you've finished the work.. I'm interested in what you've said. 3、whether与if都可以引导宾语从句,常可互换。但下面情况不能互换。 ①宾语从句是否定句时,只用if,不用whether。 e.g. I wonder if it doesn't rain. ②用if 会引起误解,就要用whether。 e.g. Please let me know whether you want to go.(此句如果把whether改成if,容易当成条件句理解 ③宾语从句中的whether 与or not直接连用,就不能换成if;不直接连用,可换。 e.g. I don't know whether or not the report is true.
