The explosion of the earth produced water vapor, which turned into water when the earth cooled down. Water allowed the earth to dissolve harmful gases into the oceans and seas. That made it possible for life to begin to develop. The arrival of small plants encouraged the development of early shellfish and all sorts of fish. Many millions of years later the first green plants began to appear on land. Later land animals appeared. Some were insects. Others, called amphibians, were able to live on land as well as in the sea. When the plants grew into forests, reptiles appeared for the first time. Later, dinosaurs developed. They became the most important animals on the earth for millions of years. After they disappeared, mammals became more important. They were the last group of animals and they were different because they produced their young from within their bodies. Small clever animals, with hands and feet, appeared and spread all over the earth. As time went by, they covered the earth and have become the most important animals on the planet. 2.

6 What she said is not yet known. 7 That we shall be late is certain. 8 It’s certain that we shall be late.

What part does the underlined part serve as in each sentence? Or find its subject in each sentence. Step 3 Grammar 定义：

用作主语的从句叫主语从句，它是名词性从句之一。引导主语从句的连接词有：连词that, whether；连接代词who, what和which；连接副词when, where, how和why。

1) 由what等代词引起的主语从句：

What the teacher said today was quite right.

老师今天说的话是十分正确的。

2) 由连词that引起的主语从句：

That they are badly in need of help is quite clear. 他们急需帮助，这是十分明显的。

但是这类句子在大多数情况下会放到整个句子的后部去，而用代词it作形式主语。

3) 由连接代词或连接副词以及whether引起的主语从句。

Whether they will sell the house is not yet decided.他们是否卖掉这所房子还没有决定。

4) whatever, whoever也可引导主语从句。

Whatever was said here must be kept secret.

这里说的话都应当保密。

Whoever makes mistakes must correct them. 凡犯了错误的人都必须改正。

注意: 上述例句中的主语从句都是放在句首, 但有时为了使句子结构平衡, 避免

“头重脚轻”, 常用

it 作形式主语, 而把从句放在后面。

例如:

It is a pity that she has made such a mistake.她犯了这样一个错误, 真是遗憾。

这样就构成了下面一些常用句型:

1) It is + adj. / n. +从句

It is a pity/shame that... 遗憾的是……

It is possible that...

很可能……

It is unlikely that...

不可能……

2) It +不及物动词+从句

It seems/appears that...

似乎……

It happened that...

碰巧……

3) It + be +过去分词+从句

It is said that...

据说……

It is known to all that...

众所周知……

It is reported that...

It is believed that...据信……;人们相信……

It is suggested that... 有人建议……

单个的主语从句作主语时谓语动词用单数；由

and 连接的两个主语从句作主语时，谓语动词用复数。
