have got to与got to有什么区别?

Gump Forrest有一段Kennedy接见Forrest时问他加入橄榄球全明星队有什么感受时，Forrest因为汽水喝多了说：“I got to pee.”他为什么不说I have got to pee？

I got to do something=I've got to do something=I have to do something前者在口语中更地道，更口语化.I got to跟I've got to在口语中非常普遍，但have got something的意思是have“有”。

1, 在表示一次性动作时,have to和 have got to 是可以互换的: i have (got) to be back by ten o’clock. 我必须10点前返回来。 i haven’t got to work tomorrow. 我明天不必上班。 i’ve got to do something! langdon thought. 兰登想:“我得做点什么!” 2, 但是,当表示习惯性动作时,尤其是当句中含有表示经常性的副词(如always, often, sometimes等)时,则应使用have to , 而不使用have got to: i don’t usually have to work on sundays. 通常我再星期天不必工作。 i often have to get up at 5. 我常常必须五点起床。 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. 他们那时不必为金钱而操心。 i had to walk very fast to overtake you. 为了赶上你,我不得不走得很快。 4, 最后一个区别,就是have to 前可加助动词或情态动词,或者用在进行体和完成体结构中,而have got to却不能: i shall have to help him as much as i can. 我将不得不尽我所能去帮助他。 he may have to cancel his plan. 他也许不得不取消这个计划。 people are having to boil their drinking water during this emergency. 在这个紧急情况下,老百姓必须煮沸他们的饮用水。 the administration has had to make unpopular decisions. 行政部门不得不做出不得人心的决定。

1. got是get的过去式和过去分词 加上have就是现在完成式。 Forrest“got to pee”只是之前的一个动作 并不强调对现在有什么影响 所以用过去式就可以 不需要用have got to这样的完成式 2.美语中有许多口语的内容是可以省略掉一些助动词的
