什么是名词性从句以及名从连接词的用法
01、名词性从句概念及分类
名词性从句的功能相当于名词词组,分为主语从句、宾语从句、表语从句和同位语从句。很多同学不太理解同位语从句,这里我们来讲一下。首先,什么是同位语呢,对一个名词进行解释说明的成分就是同位语,比如:She is Taylor Swift,a famous singer. 这句话中a famous singer就是Taylor Swift的同位语,解释说明她的身份。如果对名词进行解释说明的是一个句子,那这个句子就是同位语从句。比如:I didn't receive the news that the meeting had been put off. 这句话中,从句that the meeting had been put off说明了the news的内容,所以是同位语从句。
当我们要判断句子是哪种类型的名从时,步,划分从句(从句从关系词开始,在第二个谓语动词前或句末结束),第二步,从句作什么成分就是什么从句,比如下面的四个句子:
1. That she will help me made me happy.(从句位于动词前面,作主语,是主语从句)
2. I can understand what he said. (从句位于动词后面,作宾语,是宾语从句)
3. This is where I was born. (从句位于be动词后面,作表语,是表语从句)
4. The news that our team has won the match is encouraging. (从句作the news的同位语,是同位语从句)
02、名词性从句的连接词分类
我们把常考的名词性从句的连接词分为三类:
1. 从句缺主宾
2. 从句不缺主宾,缺含义
3. 从句不缺主宾,不缺含义
eg. I don’t know what you want. (从句中缺宾语,指事物,用what)
Who will win the match is still unknown. (从句中缺主语,指人,用who)
He has told me that he will go to Shanghai tomorrow. (从句中不缺主宾,也不缺含义,用that)
He asked whether I would show him the way. (从句中不缺主宾,缺“是否”的含义,用whether)
注意:whether和if在用法上有区别,但近些年已经不考查了,因为有些情况下不能使用if,它有局限性,所以大家填whether就可以了。
03、名词性从句解题步骤
1. 找出从句(始于关系词,终于二动或句末)
2. 从句是否缺主宾(缺主宾,指物用what,指人用who)
3. 从句是否缺含义(不缺主宾时看含义,不缺含义用that。缺含义的话,根据句意选择关系词)
我们一起来看一下这道题:
_______ will be sent to work there hasn’t been decided yet.
答案:Who。解析:步,找出从句(从横线开始,到第二个谓语动词hasn’t been decided前结束)第二步,从句中缺主语,指人,所以填Who。
