i've got nothing to lose 英语

问题描述:

i've got nothing to lose 英语
意思是我没什么可失去的,但我不明白的是,为什么要用i've got ..而不直接表达成I 've nothing to lose?
几乎所有句子都是have got..我就不明白不加为什么不行。

have got 是一种口语用于,等于 have.单用表示“有”,用在 have got to do 结构里表示“不得不、必须”等于 have to do,如:
I have a book.也可以说成 I have got a book.
I have something to do 也可以说成 I have got something to do.
I have to get up early 也可以说成 I have got to get up early.
只不过前者是正式用语,而后者是较为随便些的用语.但是,当 have 用作助动词表示完成时态时,不可用 have got + 过去分词代替.
