have to 和 must的区别及用法:have to 和 must均有―必须;不得不‖之意,但用法却不同。
must的用法:
⑴表示主观的义务和必要, 主要用于肯定句和疑问句, 意思为 ―必须……,得……,要……‖;由must引起的疑问句,肯定回答要用must或have to, 否定回答要用needn‘t或don‘t have to, 意思是―不必‖;must的否定形式mustn‘t表示禁止,意思是―不能,不许‖。如:
We must find a good way to learn English well.我们必须找一个学好英语的方法。 —Must I finish the work right now?我现在必须完成这个工作吗? —Yes, you must. / Yes, you have to. 是的。
(—No, you needn‘t. / No, you don‘t have to. 不,不必。) have to / have got to 的用法:
must表示一种主观的需要,而have to 表示一种客观的需要,意思是―不得不‖。如: Mother is out, so I have to look after my sister. 妈妈不在家,因此我不得不照看妹妹。
have to 的否定形式是don‘t have to, 相当于needn‘t。如:
They don‘t have to buy a computer now.他们目前没有必要买电脑。 have to 与have got to 常可以互换。
