英语句子中的动词解析
A.首先加 s 或 es的情况是：当主语是第三人称单数的时候

一个完整的英语的句子至少有一个或一个以上的动词。当句子中出现两个或两个以上的动词时，除少数的情况下，第一个动词后面的动词往往要发生变化，（1）变成doing形式；（2）变成动词to do不定式形式；（3）变成done过去分词形式。

Can you drive a car? I must finish my work today. Will you come here tomorrow?

（5）用在一些词组的后面：

（1）在一些动词want, like, wish, prefer, hope, try, begin, start, promise, forget后面：
I want to buy a computer. He prefers to stay at home. I forgot to tell you the news.
（2）用在某些tell sb. to do sth; sb. find it +adj to do sth; It is (was) +adj+ to do sth句型中：
