【简介】感谢网友“雕龙文库”参与投稿,这里小编给大家分享一些,方便大家学习。

在学习名词性从句之前,我们首先要明白一个词:复合句

什么叫复合句

由一个主句和一个或一个以上的从句构成的句子叫复合句。在复合句中主句是全句的主体,从句是全句的一个成分,不能独立。从句通常是用关联词来引导的。在这里关联词还起联系从句和主句的作用。

一、从句的种类:

主语从句、宾语从句、表语从句、同位语从句,定语从句和状语从句

二、名词性从句的连接词

1. 单纯连词

在从句中不补充当任何成分,只起到连接从句的功能。

that 没有实际意义,而whether/ if 在句子中表示“是否” 的意义。

Eg : That the prices of rice will go up is certain. (that引导主语从句,补充当任何成分)

He asked if I could come to see him this weekend.

形式主语it 代替主语从句位于句首时,常见的几种情况:

① It + adj +that 从句(大多数情况下that从句后用should+动词原形)

Adj: necessary right clear unlikely strange obvious natural important

Eg: It is necessary to learn English well.

② It +系动词+名词+that 从句

Non: a pity an honor good news a wonder a fact no wonder no surpeise

Eg: It is a fact that you are a good boy.

③ It +be + 过去分词+that从句

过去分词:said / heard/ reported/ told/ decided/suggested/thought/considered/ hoped/ announced

Eg: It is announced that the plan has been canceled.

注意:

It + be+ suggested/ advised/ ordered/ requested/ insisted/ demand+ that从句, that从句要用should +动词原形,should可以省略。

Eg: It is suggested that you (should ) spend more time in studying English .

当suggest表示“表明”时,不可以用虚拟语气

Eg: It suggests that you are an honest boy.

Insist 表示“坚持某种说法(事情已经发生过了)”,不用虚拟语气。

表示“坚持要做(事情没有发生)”,要用虚拟语气。

Eg: she insisted that I have never done such thing .

She insisted that I study abroad.

④It +动词(+宾语或状语)+that 从句

动词如: appear(显得)/ happen(碰巧)/ matter(重要)/ occur(出现)/ turn out(结果是)

Eg: It happened to me that I was away when he came.主语从句不可位于句首的五种情况:

注意:

(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。

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。

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。

正确表达:It doesn’t matter whether he is wrong or not.

错误表达:Whether he is wrong or not doesn’t matter.

(5)含主语从句的复合句是疑问句时,主语从句不可提前。

正确表达:Is it likely that it will rain in the evening?

错误表达:Is that will rain in the evening likely?
