语法规则

一、主语从句的定义

在主从复合句中充当主语的从句即为主语从句。主语从句的位置可以在句首， 也可以用it作形式主语， 主语从句放在后面。

❶What please me most is that their artistic talent is extremely shocking.

最让我高兴的是，他们的艺术天赋是非常惊人的。

❷It worried the mother that her son was always playing computer games.

儿子总玩电脑游戏，这让他的母亲很担心。

❸It is not a problem whether we can win the battle; it's just a matter of time.

我们能否打赢这场战斗不是问题；这只是时间问题。

二、主语从句的连接词及其句法功能

1．连接词that和whether/if

(1)that在从句中不充当任何句子成分，本身无任何意义，只起连接作用，但不可省略。

❶That my parents always treat me as a little child makes me very unhappy.

我的父母总是像对待小孩子那样对我让我很不开心。

❷That the college will take in more new students this year is true.

今年这所大学将招收更多新生是真的。

(2)whether/if在从句中不充当任何句子成分，起连接作用，意为“是否”，不可省略。

❸Whether the plan will be carried out is still unknown.

＝It is still unknown whether the plan will be carried out.

这个计划是否会实施还不知道。

2．连接代词(who, whom, whose, what, which, whichever, whoever, whomever, whatever等)

连接代词引导主语从句，在从句中可以作主语、宾语、表语或定语。

❶Who will go to the concert is not known.

不知道谁会去音乐会。

❷Whoever breaks the law will be punished.

无论谁触犯法律都会受到惩罚。

❸Whatever you do in your spare time should do no harm to others.

你在业余时间做的任何事情都不应该伤害其他人。

3．连接副词(when, where, how, why等)

连接副词引导主语从句并在从句中作状语。

❶How this happened is not clear to anyone.

这件事是怎样发生的，谁也不清楚。

❷When we will have a meeting is an important question.

我们何时举行会议是一个重要的问题。

❸Where I spend my summer is no business of yours.

我在哪里过暑假不关你的事。

　确定名词性从句引导词的步骤：

(1)分析句式结构，明确名词性从句在句中的功能；

(2)明确名词性从句所表达的意义；

(3)明确名词性从句中所需要的成分及意义；

(4)确定名词性从句的连接词。[巧学活用1]　用适当的连接代词或连接副词填空

①________ made him embarrassed was that one of his buttons was missing.

②________ makes the most beautiful kite will win a prize in the Kite Festival.

③________ he will attend the meeting or not doesn't matter.

④It is obvious to the students ________ they should get well prepared for their future.

⑤________ he gave up the chance of studying abroad is unknown.

二、主语从句中用it作形式主语的结构

1．It＋be＋形容词(obvious, true, natural, strange, etc.)＋主语从句

It is important that he should know about this.

重要的是他应该知道此事。

[名师点津]　在“It＋be＋形容词＋主语从句”结构中，若形容词为important/necessary/strange等，主语从句中的谓语用“should＋动词原形”形式，其中should可省略。

2．It＋be＋名词词组(no wonder, an honour, a pity, a/no surprise, etc.)＋主语从句

It's a pity that he didn't attend the opening ceremony.

很遗憾他没参加开幕式。

3．It＋be＋过去分词(said, reported, thought, expected, proved, etc.)＋主语从句

It is suggested that the meeting be put off.

有人建议会议应当被推迟。

[名师点津]　在“It＋be＋过去分词＋主语从句”结构中，过去分词若为suggested/ordered/required/advised等，主语从句中的谓语用“should＋动词原形”形式，其中should可省略。

4．It＋不及物动词(happen, seem, appear, remain, etc.)＋主语从句

It seems that it is going to rain.

看起来好像要下雨。

5．It＋及物动词＋宾语＋主语从句

It surprised him why they came to visit him suddenly.

让他吃惊的是他们为什么突然都来看他。
