have在英语中是个很活跃的动词，从形式上有have, has, had三种，其用法分为两类：

1.用作实义动词

（1）当“有”讲，有时和“go”连用，主语为第三人称单数时需用“has”形式，其他多用“have”，如：

I have a brother and a sister.我有一个哥哥和一个姐姐。

She has two books.她有两本书。

（2）在英国，当have用作实义动词时常和got连用，亦表示“有”，而在美国英语中没有此用法，如：

Smith has got a new car.史密斯有辆新车。

Xiao Li has got several dictionaries.小李有好几本字典。

（3）如果用在疑问句中时，回答用have，如：

—Have you got a table?你有桌子了吗？

—Yes,I have.是，我有了。

2.用作助动词

（1）当“have”用作助动词时常和动词的过去分词形式连用，构成“have/has+动词过去分词”表示动作已完成，如：

He has studied in America for two years.他在美国学习了两年。

I have taken the medicine.我已经吃过药了。

She has been to Beijing for three times.她去过北京三次。

（2）若表过去已完成则用“had+动词过去分词”，如：

The film had started when we got to the cinema.

我们到达电影院时电影已经开始了。

They had finished two-thirds of this project by the end of last week.

到上周末他们已经完成了这项工程的三分之二。
