3）That’s a bit expensive.

2) One is not enough for me. I want one more.

3) One of them is English.

4) Suddenly one of the bags fell off the truck.

4. 不定式作主语: 动词不定式表示比较具体的意义，经常和特定的动作和执行者联系起来，经常带

时间或地点状语，有时表示将要发生的动作。

1) To master a foreign language is no easy job.

2) To do it well is my earnest desire.

3) To see this film is to waste time.

4) To solve this problem is out of the question.

**动词不定式作主语时，常见的另一种形式是在句首用先行代词it

作形式主语，而将动词不定式移到谓语之后作真正主语。用于这种形式是一些特定形容词，动词和名词。如：

1)形容词作表语(常见的形容词有：important，difficult，easy等)

It is foolish to act in this way.

2)动词作谓语(常见的动词有：require，cost，amuse等)

It didn’t occur to me to ask him to help me.

3) 名词作表语:

It is a good idea to think this way.

5. 动名词作主语

1) Being happy is better than being king.

2) Worrying never does anyone good.

3) Yaoming’s rejoining in the team makes the teammate excited.

(动名词作主语，前面可加代词或名词的所有格做其逻辑主语。)

4) Collecting stamps is a good hobby.

5) Swimming is a best sport in summer.

（动名词表示比较抽象(一般)和经常性的意义，有时可同不定式互换。）

6）There is no telling what will happen.

7) There is no denying the fact.

8) There is no need informing him of it.

9) 形容词作表语(常见的形容词有：enjoyable，good，hard，worthwhile)

It is nice talking to you.

10) 名词作表语

It’s a waste of time doing this.

（在句首用先行代词it作形式主语面将动名词短语移至谓语之后作真实主语。）

**主语为动词不定式和动名词时，其谓语常用单数形式。如：

To give is better than to receive.

It was difficult to see.

It’s best to wear cool clothes.

Playing is much better than having classes.

6. 词组作主语

1）Early to bed and early to rise makes a man healthy，wealthy and wise.
