中小学英语语法辅导大全(8)

Word came that he had been abroad. (同位语从句) Our team has won the game, which made us very happy. 我们的队赢了,这让我们很高兴?(定语从句) The doctor whom you are looking for is in the room. 你找的那位医生在房间里面?(定语从句)

His mother did all she could to help him with his study.他妈妈尽她的最大努力帮助他的学习?(定语从句,代词all作先行词?) 2. 从性质上区别

定语从句是从句对其先行词的修饰或限制,属于形容词性从句的范畴;而同位语从句是从句对前面抽象名词的进一步的说明和解释,属于名词性从句的范畴。如:

The news that our team has won the game was true. 我们队赢了那场比赛的消息是真的?(同位语从句,补充说明news到底是一个什么消息?)

The news that he told me yesterday was true. 昨天他告诉我的那个消息是真的?(定语从句,news在从句中作told的宾语?)

I made a promise that if anyone set me free I would make him very rich. 我许诺如果谁让我自由,我就让他非常富有?(同位语从句,补充说明promise到底是一个什么诺言?)

The mother made a promise that pleased all her children. 妈妈做出了一个令她的孩子们高兴的许诺?(定语从句,promise在从句中作pleased的主语?) 3. 从引导词及其在句子中的成分上区别

有些引导词如how, whether, what可以引导同位语从句,但不能引导定语从句?如:

That question whether we need it has not been considered. 我们是否需要它这个问题还没有考虑?(同位语从句)

I have no idea what has happened to him. 我不知道他发生了什么事?(同位语从句)

引导词that引导定语从句时,在从句中一般作主语或宾语(指物时还可以用which代替),并且作宾语时常常省略?that在同位语从句中仅起连接作用,不充当任何成分,并且不能省略,也不能用which来代替?如:

The order that we should send a few people to help the other groups was received yesterday. 我们应派几个人去帮别的几个小组的命令昨天收到了?(同位语从句,是对order的具体解释,that虽不作成分,但不能省略?) The order that we received yesterday was that we should send a few people to help the other groups. 我们昨天收到的命令是我们应该派几个人去帮助别的几个小组?(定语从句,是名词order的修饰语,that在从句中作received的宾语,可以省略?) 巩固性练习：

名词性从句之主语从句专项语法讲义

一、主语从句的连词分三类

（1）从属连词引导的主语从句 （that whether if）

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。That 引导主语从句通常用it 作形式主语。

例如：That you will win the medal seems unlikely. That she survived the accident is a miracle.

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。 注意：引导主语从句，不能用if不能在开头，只能用whether。

Whether we will hold a party in the open air tomorrow depends on the weather. Whether she is coming or not doesn‘t matter too much. （2） 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. Whatever we do is to serve the people. 注：whatever / whoever的功用

whatever, whoever在主语从句中不含疑问意义。它引导主语从句，并在从句中作主语、宾语、表语等。 whatever = anything that; whoever = anyone who。要注意和whatever, whoever引导的让步状语从句的区别。 如：Whoever breaks the law should be punished. （主语从句） （ ＝Anyone who breaks the law should be punished. ）

Whoever breaks the law, he should be punished. （让步状语从句） （ ＝No matter who breaks the law, he should be punished. ）

（3）用连接副词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。) 例如:Where we should leave it is a problem.
