I have a new book.和I 've got a new book.有什么不同

一般情况下通用.不过要注意以下：
一,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.

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

二,在下列情况下不能用 have got 来代替 have.
1.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?
2.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.
3.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
