姓名： 评价： 一、【学习目标】

掌握名词性从句中主语从句的用法。

二、【自主学习】

1

请同学们在本课上课前自找时间阅读学习课本92页主语从句的用法。

2

观察下列句子，想想划横线的词做什么成分？

1)

The book was stolen. （主语）

2)

He finished his homework on time. （动词的宾语）

3)

Dr. Smith is going to pull out one of my teeth. （介词的宾语）

4)

We students should study hard. （同位语）

5)

My brother is a worker. （表语）

思考：什么是名词？名词在句子当中一般可以作什么成分？

总结：名词表示人或事物的名称的词。

名词在句子可以充当主语、宾语、表语、同位语。

联想：名词性从句包括主语从句、宾语从句、表语从句、同位语从句四种。

三、【合作探究】

Question 1: 什么是主语从句？

观察下列三组句子，想想分别是由来什么充当主语。

1.

Something was wrong. （名词）

2.

What he said was right.

（从句）

3.

The wish was an end to all the wars of the world. （名词）

4.

What he wanted to see was an end to all the wars of the world. （从句）

5.

The news made his parents and teachers happy. （名词）

6.

That he was admitted into Beijing University made his parents and teachers happy. （从句）

总结: 在主从复合句中，代替名词充当主语的从句，即为主语从句。

Question 2: 主语从句由什么词引导？（通过观察课文中出现的&上述主语从句）

请从课文中找出下列句子，并填上所缺的词。

1.

What it was to become was uncertain until between 4.5 and 3.8 billion years ago…

13

2.

What is even more important is that as the earth cooled down…

3.

What many scientists believe is that the continued presence of water allowed the earth …

4.

Why they suddenly disappeared still remains a mystery. 5.

So whether life will continue on the earth for millions of years to come will depend on ... 6.

… it was not clear whether the shape would last or not. 7.

It was not immediately obvious that

water was to be fundamental to the development of life. 总结:

从属连词：that, whether,

连接代词：who(ever), whom(ever),

which(ever),what(ever),whose

连接副词：when, why, where, how ①that在从句中(充当/不充当)成分,(有/没有)意义,(能/不能）省略。

②whether/if在从句中(充当/不充当)成分,(有/没有)意义, “是否”; if（能/不能）引导主语从句。

③连接代词和连接副词在从句中(充当/不充当)成分，(有/没有)意义。

Question3: 什么是形式主语？

观察下列句子，找找真正的主语是什么？

1.

It is clear that somebody came to visit him just now. 很明显刚刚有人来拜访过他。

2.

It is a pity that he didn’t come to the party. 可惜的是他没来参加晚会。

3.

It is reported that the rain will stop tomorrow. 据报道，明天雨会停。

4.

It appeared to scientists on the earth that the stars had moved.

在地球上的科学家看来，这些星球已经移动了。

总结：当主语由从句充当时，很多时候为了使句子保持平衡，而使用it作为形式主语，而主语从句作为真正的主语放于句尾。

相关句型：（1）It+ be +形态词+that+从句（例句1）

（2）It+ be +名词+that+从句（例句2）

(a pity, a shame, a fact, an honour, a wonder, no wonder) （3）It+ be +过去分词+that+从句（例句3）

It is known that…;

It is said that …;

14

It is believed that…;

It is hoped that…

（4）It+ appear/seem/happen/matter + that+从句（例句4）

Question4: 主语从句应该要用什么语序？

Where the professor lives is still unknown to us. Whether he will attend the party depends on the party.

总结：

主语从句的语序要用陈述语序，即：连接词+主语+谓语+其他成分
