Question

would have to跟will have to和have to有什么区别？

Answer 1

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。
