Question

have got to和have got的区别

Answer 1

1， 在表示一次性动作时，have to和 have got to 是能够互换的：
I have (got) to be back by ten o’clock.
本人必需10点前返回来。
I haven’t got to work tomorrow.
本人明天不用上班。
I’ve got to do something! Langdon thought.
兰登想：“本人得做点什么！”

2， 但是，当表示习气性动作时，特别是当句中含有表示经常性的副词（如always, often, sometimes等）时，则应运用have to , 而不运用have got to:
don’t usually have to work on Sundays.
通常本人再星期天不用工作。
I often have to get up at 5.
本人常常必需五点起床。

3, have to 与 have got to 的另一区别，就是后者不大用于过去时。
They didn’t have to worry about money.
他们那时不用为金钱而操心。
I had to walk very fast to overtake you.
为了赶上你，本人不得不走得很快。

4， 最后一个区别，就是have to 前可加助动词或神态动词，或者用在停止体和完成体构造中，而have got to却不能：
I shall have to help him as much as I can.
本人将不得不尽本人所能去协助他。
He may have to cancel his plan.
他或许不得不取消这个方案。

have got to 和 have to 的区别
have to与have got to含义相同，常可以互换。区别在于：
have to构成否定句和疑问句时通常须加do;
have got to 为英国英语在口语中的用法，只需用have或has构成否定句或疑问句，
如：
You don't have to knock—just walk in.

Does she have to stay at home every night?

只是在文语中have to可直接构成问句，
如：

Have we to make our own way to the conference?

Why have you got to take these tablets? 你为什么要吃这些药片？

You haven't got to take flowers but many people do.

你不必非带花去不可，但是许多人都带着花去。
