这种简写是规则，没有什么可说的啊。
它就是现在完成时。
(1)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? (×)
(2)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, etc.
