同学好：
在英语口语中，常用have got 代替have ，作“有”解。
I have a bike. = I have got a bike.

其否定式为：
I don’t have a bike. = I haven’t a bike.
I haven’t got a bike. (√)
I don’t have got a bike. (×)

其疑问形式为：
Have you a bike? / Have you got a bike?
Do you have a bike? (√)
Do you have got a bike? (×)

在下列情况下不能用have got 来代替have。
A. 在情态动词，助动词或动词不定式之后，只能用have，不用have got。如：
May I have some more tea?我可以再喝点茶吗？
Would you like to have another apple?你想再吃一个苹果吗？

B. 在过去时，完成时或进行时中，不用 have got，而用have。如：
Li Hong had a problem.李红有一个问题。
I have had the bike for three years.我买这辆自行车已经3年了。

C. 固定短语中不用have got。
have a rest/ a swim/ a wash/ a drink
have lunch, have a meeting, have a party

祝学习愉快！
