2025年6月大学英语四级语法考试知识点定语从句篇:表语从句

表语从句的概念

表语从句是指在句子中充当表语的从句,用于说明主语的内容、特点或状况。它一般由连接词引导,整个从句在句子中等于一个名词,起到表语有哪些用途。

表语从句的容易见到种类及例句

1. 由 that 引导的表语从句

that 在从句中不作成分,但一般不可以省略。

例句:

“The fact is that we have lost the game.”

“The truth is that he never came back.”

四六级考试知识点:在写作中,that 引导的表语从句常用于表达事实或看法。比如:

“The problem is that we dont have enough time to finish the project.”

2. 由 what 引导的表语从句

what 在从句中作主语、宾语或表语,表示“……的东西/事情”。

例句:

“The question is what we should do next.”

“The secret is what he never told us.”

四六级考试知识点:在完形填空或语法选择题中,或许会考查 what 的使用方法。比如:

“The challenge is _____ we can find a solution.”

A. that

B. what

C. which

D. who

答案:B. what

3. 由 who/whom/whose 引导的表语从句

这类连接代词在从句中分别作主语、宾语或定语。

例句:

“The winner is who we expected.”

“The person we are looking for is whom you saw yesterday.”

四六级考试知识点:在阅读理解中,或许会出现类似的结构,需要理解句子的逻辑关系。比如:

“The best candidate is who has the most experience.”

4. 由 whether/if 引导的表语从句

whether 和 if 都表示“是不是”,但在表语从句中一般用 whether,特别是与 or not 连用时。

例句:

“The doubt is whether he will come or not.”

“The problem is whether we can afford it.”

四六级考试知识点:在写作中,可以用 whether 来表达不确定性。比如:

“The question remains whether the new policy will be effective.”

5. 由 how/when/where/why 引导的表语从句

这类连接副词在从句中作状语。

例句:

“The mystery is where he disappeared.”

“The reason is why he didnt show up.”

四六级考试知识点:在完形填空或语法选择题中,或许会考查这类连接副词的使用方法。比如:

“The key is _____ we can solve the problem.”

A. how

B. when

C. where

D. why

答案:A. how

表语从句的特殊结构

1. 形式主语 it 的用法

当表语从句较长或句子结构复杂时,一般用 it 作形式主语,而将真的的表语从句放在句子后面。

例句:

“It is a fact that we need more time to complete the project.”

四六级考试知识点:在写作中,用形式主语可以使句子愈加简洁。比如:

“It remains a mystery how the ancient pyramids were built.”

2. 表语从句与系动词的搭配

表语从句常与系动词搭配,表示主语的状况或特点。

例句:

“The truth is that he has already left.”

“The idea seems that we should try again.”

四六级考试知识点:在阅读理解中,特别是涉及看法或事实的句子中,这种结构非常容易见到。比如:

“The conclusion is that climate change is a global issue.”

例题:

“The problem is _____ we can find a solution.”

C. when

D. where

答案:B. whether
