主语从句和表语从句

主语从句和表语从句

知识点

1.名词性从句引导词的选择

选择原则“缺什么，补什么，什么不缺，用that”

“什么不缺，用that”的意思是：如果从句中不缺任何成分，而且句意完整时，就用that来引导主语从句或表语从句以及其他的名词性从句。

2.whether 意为“是否”，引导的主语从句放在句首，不能用if

代替；但当用

it 作形式主语时，whether引导的主语从句放在句中或句末，此时可换用if. It is doubtful whether there’ll be any seats left.说不上是否还有座位了。

3.that 引导主语从句时，只起连接作用，不作任何成分，没有实际意义。在句

首时不可省略。What引导主语从句时既要起连接作用，又要在从句中作主语或宾语，在任何情况下都不能省略，它具有具体意义，表示“什么，所……

的（事、物、话）”，相当于all that/ everything that. Which引导主语从句也作成分，它表示选择的意义，常译为“那个”。如：That he survived in the earthquake is a miracle. 他在地震中幸免于难，这是个奇迹。

4.关系代词what, which, who引导主语、表语从句时含有疑问意义，而whatever,

whichever, whoever在引导名词性从句时，往往比what, which,

who更强调，不表示疑问意义。而且whatever=all that/everything

that; whichever=anything that;

whoever=anyone who.另外，whatever=no matter what时引导状语从句。如：Whatever is worth doing at all is worth doing well.凡是值得做的事情都值得好好地做。

各类从句详解

英语从句可以分为名词性从句、定语从句和状语从句三大类：下面我们逐一进行说明：

一、名词性从句（主语从句、表语从句、宾语从句、同位语从句）

主语从句、表语从句、宾语从句和同位语从句在复合句中的充当的成分和其名称相同，分别作主句的主语、表语、宾语和同位语。上述这四种从句均被称为名词性从句。所有的名词性从句均不能用逗号分开，并且它们都用相同的关联词，关联词如下：

①主从连词：that (无意义), whether (是否), if (是否)（在句子中不充当任何成分）

②连接代词：who (谁), whom (谁), whose (谁的), what (什么), which (哪一个)

③连接副词：when (什么时候), where (什么地方), how (怎样), why (为什么)

主从连词只起连接作用，连接代词和连接副词除了起连接作用外，还充当从句某一个成分。另外，可以用whatever, whichever, whoever, who(m)ever等连接代词引导名词性从句，来加强语气。

下面分别对各种名词性从句进行介绍

（一）主语从句（subject clause）

在主句中用作主语的主谓结构称之为主语从句。

例如：

That he will come to the discussion is certain.他来参加讨论是确定的。

That the moon moves round the earth is well known to all of us.月球绕地球转动，这是我们大家都熟知的。

When the meeting is to be held has not yet been decide.会议什么时候召开还没有决定。

主语从句放在句首，句子常常显得比较笨重，因此通常可以把it放在句首，作形式主语，而将主语从句放在后面。例如上面的句子可以分别改写为：

名词性从句〔主语、表语、宾语、同位语从句〕

（一） 主语从句

1． 定义：用作主语的从句叫做主语从句。

2． 构成：关联词+简单句

3． 引导主语从句的关联词有三类：

(1) 附属连词that。 如：

That they were in truth sisters was clear from the facial resemblance between them.

很明显，她们确是亲姐妹，她们的脸型很相似。

(2) 附属连词whether。如：

Whether he’ll come here isn’t clear. 他是否会来这里还不清楚。

(3) 连接代词who, whom, whose, what, which, whoever, whatever, whichever

连接副词 where, when, how, why。如：

What she did is not yet known. 她干了什么尚不清楚。

解释：

1． 主语从句能用it作形式上的主语。常以it作形式主语的句型有：

A. It+be+形容词(obvious, true, natural, surprising, good, wonderful, funny, possible, likely, certain,

probable, etc.)+that从句。如：

It is certain that she will do well in her exam. 毫无疑问她考试成绩会很好。

B. It+be+名词词组(no wonder, an honour, a good thing, a pity, no surprise, etc.)+that从句。如：

It’s a pity that we can’t go. 很遗憾我们不能去。。

C.It+seem, happen等不及物动词及短语+that从句。如：
