非谓语动词指的是在句中起名词，形容词或副词作用的动词形式，而不是作谓语的动词形式。动词的非谓语形式分为动名词，分词，动词不定式。

Climbing mountain is a good exercise. (Climbing..., 动名词起名词作用)

爬山是一项好运动。

Do you know the man wearing a white shirt. (wearing ... 分词起形容词作用) 你认识那个穿白衬衣的人吗?

He gets up early to catch the first bus. (to catch .... 不定式起副词作用) 他早早起床是为了赶上第一班汽车。

谓语动词和非谓语动词的区别：

1) 谓语动词在句中可单独作谓语，而非谓语动词不能单独作谓语。

Miss Mary teaches us English.

玛丽教我们英语。(teaches 动词作谓语)

Mr.Victor came to our classroom to have a talk with us last week.

维克托先生上周来到了我们教室和我们谈话。 (to have a talk.... 不定式作状语)

2) 谓语动词受主语的人称和数的限制，而非谓语动词形式没有这种限制。

Larke likes the pop music.

拉克喜欢流行音乐。 (动词用单数第三人称形式)

Larke has nothing to do today.

拉克今天没什么事要做。(do 用原形)

非谓语动词的特征：

1 如果非谓语动词是及物动词，后面须跟宾语。

Studying English is my favorite.

学习英语是我的爱好。(studying 后跟宾语)

To help him is my duty.

帮助他是我的责任。(help 后跟宾语)

2 非谓语动词可以带有自己的状语或逻辑主语。

在这样的环境下工作太可怕了。(under such a condition 是 working 的状语) It's too difficult for him to master English in such a short time.

他在这么短的时间内掌握英语太难了。(for him 作不定式的逻辑主语)

3 非谓语动词仍有语态和时态的变化。

I am sorry to have kept you waiting long.

对不起让你久等了。(to have kept...是不定式的完成形式)

从山上看，这座城市美丽多了。(Seen from...是分词的被动形式)

4 非谓语动词在句中可以当成名词或者形容词来使用。

Our coming made him happy.

我们的到来使他很高兴。(coming 起名词作用)

动词不定式：
