名词性从句引导词分类

名词性从句的引导词可以分作四类：连接词，连接代词，连接副词和“疑问词-ever”等。

1. 连接词（不作成分）：①that（无实际意思）

②whether, if“是否”（疑问含义）

2. 连接代词（作主、宾、表语）：①who, whom

②what, which

3. 连接副词（作状、表语）：when，where, why, how

4. 疑问词-ever：whoever, whomever, whatever, whichever

As many as five courses are provided, and you are free to choose ________ suits you best.

A. whatever

B. whichever

C. whenever

D. wherever

答案：B

思路分析：本题考查宾语从句连接词。分析句子结构可知，所填内容引导宾语从句，且

在从句中作主语，而C，D两项作状语，可排除；另外，由信息词five courses与choose可

知是在给定的范围中做出选择，故排除whatever“无论什么”，选择whichever“无论哪个”。句意：提供了多达五门课程，你可以自由选择最适合你的那一门。

名词性从句引导词的省略问题

名词性从句中的省略仅涉及that，其他引导词均不可省略。

1. 主语、表语、同位语从句中that均不可省略；

2. 宾语从句中that多数情况下可以省略；

3. that引导宾语从句中以下情况不可省略：

①介词后引导宾语从句that不可省；

②并列宾语从句中自第二个起that不可省；

③it作形式宾语，that引导宾语从句，that多不可省。

①I know nothing about him except that he is going abroad for further education.

我对他一无所知，除了知道他即将出国深造之外。

⑥He heard the news that his team had won.

A. that; what

B. what; that

C. 不填；that

D. that; 不填

答案：C

思路分析：两空所填的答案均引导宾语从句，视为and连接的两个宾语从句，分别分析从句结构发现，引导词均不作成分，没有实际意思，故而应选择that，而同时又知道并列宾

语从句中第二个起that不可省略，故而应当选择C。

名词性从句引导词的辨析

（一）that和what的选用

that和what都可引导所有的名词从句。但是，what除起连接作用外，还在名词性从句

中充当成分，可作从句的主语、宾语、或表语。而that在名词性从句中不充当任何成分，只

起连接作用。

What he wants to tell us is not clear. 他要跟我们说什么，还不清楚。

That’s just what I want. 这正是我想要的。

It is certain that he will do well in his new job. （主语从句）

Do you know that he has been admitted to Beijing University? （宾语从句）

My decision is that we are to start at 6 tomorrow morning. （表语从句）

The news that our team had won the game excited everybody. （同位语从句）

当用that引导从句时，需注意以下情况：

1. 在主语从句中，that一般不可省略，尤其是当主语从句位于句首时，它绝对不可省略。

如：
