Learning about language

名词、代词、数词、不定式、动词的ing形式、从句等可作句子的主语。

1.

名词作主语

A big tree has fallen across the street. The ambulance is arriving. 2.

代词作主语

You are a middle school student. She lent me her new bike. 3. 数词作主语

Five is enough. Two from five leave three. 4.不定式作主语

To find the truth is very difficult. It’s is very difficult to finish the work.

5. 动名词作主语

Smoking is bad for your health. Seeing is believing. 注意：

A. 动名词与不定式都可在句子中作主语。动名词作主语时一般来说指的是一个概念或一个既成事实。如：

Teaching English is my job.

Teaching English 是一个概念名词，而不是一个动作。

B. 当一个不定式短语作主语时，我们常用it作形式主语，而把真正的主语—动词不定式放到句子后边。

这样的句型还用在It’s…for sb. to do…It’s…of sb. to do…中。如果It’s后边的形容词与人的天资、秉性有关时，必须用It’s…of sb. to do…；这类形容词包括

good, bad, clever, stupid, wise, foolish, cruel, mean 等。如果It’s后边的形容词与人的天资、秉性无关时，则要用It’s… for sb. to do…。

6.

名词化的形容词作主语

The rich should help the poor. Old and young walked side by side. 7. 名词化的过去分词作主语

The disabled are being carefully taken care of. 8.从句作主语

作主语的从句称为主语从句，

可由that，whether，wh-词等引导。

Whenever you come will be fine. 9.

有时介词短语、副词或其短语位于主语位置是倒装结构

Between six and seven in the morning is the time I go jogging．

Nearby is a good place for camping．

用

it 作形式主语的句型有：

(1) It is + 形容词(possible, clear, true, necessary, likely , nice 等) + that

(2) It is + 名词

（a pity , no use , a fact, no wonder 等）+ that

(3) It + 不及物动词（follows, happens,

turns out, goes without saying）+ that

(4) It is + 过去分词（thought, known,

mentioned, said, expected, suggested, may be safely said, must be admitted, has been decided ）+ that

在以上句型中it是形式主语, 真正的主语是that引导的从句。在这样的主语从句中that不能省略, 就其本质讲，用That…is well-known; That…is said也是可以的。但是经过长期使用, 上述句型已经被固定下来。
