不定式有很多式,其中你先掌握一般式哦,如果这些都明白了 我再给你看看其他的。这个是基础哦·

不定式一般式就是指“to+动词原形”,其主要用法如下:
1. 表示未发生的动作,即表示发生在谓语动作之后的动作。如:
We decided to leave early. 我们决定早点动身。
He asked me to buy him some paper. 他叫我给他买些纸。

2. 表示同时发生的动作,即表示与谓语动作同时发生或略先于谓语动作的动作。如:
She is helping us to clean the window. 她在帮我们擦窗户。
I’m sorry to hear that. 听到这事我很难过。

3. 表示一般情况,即看不出动作的先后关系,而是表示一种情况或现象。如:
Washing the car seems to be your main hobby. 擦洗汽车似乎是你的主要爱好。
None of her many lovers seemed to want to marry her. 在她的许多情人节中似乎没有一个愿意娶她的。

动词不定式的五种“式”

不定式根据其发生的时间不同以及所处的状语的不同,可以有一般式、完成式、进行式、完成进行式,同时根据它与逻辑主语的关系的不同,可以有主动式和被动式。

一、不定式一般式的用法
1. 表示未发生的动作
即表示发生在谓语动作之后的动作。如:
I expect him to arrive tomorrow. 我预计他明天到达。
I hope to catch an early train. 我希望赶上早班火车。
The doctor advised me to take a complete rest. 医生建议我完全休息。

2. 表示同时发生的动作
即表示与谓语动作同时发生或略先于谓语动作的动作。如:
Who heard him say that? 是谁听到他这样说的?(say与heard几乎同时发生)
I’m sorry to hear that. 听到这事我很难过。(to hear 略先于am sorry)

3. 表示一般情况
即看不出动作的先后关系,而是表示一种情况或现象。如:
Washing the car seems to be your main hobby. 擦洗汽车似乎是你的主要爱好。
None of her many lovers seemed to want to marry her. 在她的许多情人中似乎没有一个愿意娶她的。

二、不定式进行式的用法
1. 表示同时进行
即表示与谓语动作同时发生且正在进行的动作。如:
He seems to be following us. 他似乎在跟着我们。
He pretended to be looking for a book. 他假装在找书。
I happened to be looking out of the window when they arrived. 他们到达时我碰巧正向窗外望去。

2. 表示将来
正如可用进行时态表示将来意义一样,不定式的进行式有时也可表示将来。如:
You are lucky to be going by air. 你挺幸运的,能乘飞机走。
He was happy to be coming home. 就要回家了他感到高兴。
I happened to be going that way. 我恰好也是到那里去。
I promised to be waiting at the door when he came out. 我答应在门口一直等到他出来。

3. 表示一般情况
即看不出动作的先后关系,而是表示一种情况或现象。如:
I noticed that he seemed to be smoking a lot. 我发现他似乎烟瘾很大。
Just to be doing something was a help. 做点事是有益处的。
You are too young to be meeting young men. 你太小,不能交男朋友。
