答:have to与 must的区别
1.have to有人称和数的变化,即第三人称单数用has to,其他人称用have to;而must没有人称或数的变化。例如:
He has to go there.他必须去那里。
She must be off now.她现在必须走了。
2.have to有时态的变化,must没有。例如:
He told me that I must be at the station by ten.他告诉我必须十点前到达车站。
He had to pay for it.他不得不赔偿。
3.have to强调客观上“不得不”做某事;must指主观上“必须”做某事。例如:
We must study hard.我们一定要努力学习。
He had to go on foot because there was something wrong with his car.因为他的汽车坏了,他不得不走着去。 |
