在第54文章,我们已经学习了 "must" 和 "to have to" 动词。今天我们将学习 "must" 和 "to have to" 的疑问句。让我们先从 "must" 的疑问句开始。
"must" 的疑问句
看这些疑问句:
Must you go now?(你现在必须离开了吗?)
Must we pay this bill today?(今天我们必须付这张发票吗?)
Must they make so much noise?(他们一定得这么吵吗?)
请记住,"must" 是一个情态动词,所以不需要使用助动词来构成疑问句。如你所见,我们只需要把 "must" 再后接主语和动词即可。
"must" 疑问句的回答
让我们来看 "must" 疑问句的回答。看这些例子:
Must you go now?(你现在得离开了吗?)
Yes, the babysitter is waiting.(是的,保姆正在等我们)
Must we pay this bill today?(今天我们必须付发票了吗?)
Yes, today is the last day.(是的,今天是最后一天)
当回答具有 "must" 的疑问句时,通常会说 "yes" 并接着给予一个需要 或 责任的原因;或也可以给予一个简略回答,例如:
Must you go now?(你现在必须离开了吗?)
Yes, I must.(是的)
"must" 询问信息
我们来看如何使用 "must" 来询问信息,看这些例子:
When must we go to see the doctor?(我们何时必须去看医生?)
On Friday morning.(周五上午)
How long must we wait?(我们必须等多久?)
Only a few more minutes.(只需要再几分钟)
What must I do?(我必须做什么?)
Close your eyes and relax.(闭上眼睛并放轻松)
很容易,对吧?我们只需要再 "must" 前面加一个疑问词即可。
"to have to"的疑问句
现在我们来看 "to have to" 的疑问句。虽然使用 "must" 的疑问句很容易,但 "to have to" 的使用更频繁而且没有 "must" 那么正式。请记住, "to have to" 是规则动词,要用 "do" 或 "does" 助动词来构成疑问句。看这些例子:
Do you have to work on Saturday?(你周六得工作吗?)
Do I have to wear a uniform?(我得穿制服吗?)
Does he have to go to work by bus?(他得搭公交汽车去上班吗?)
同样要记得,"to have to" 的第三人称单数是 "has to",但请注意,在疑问句中使用 "have to",要加"does"助动词。
"have to"疑问句的回答
让我们来看 "have to" 疑问句的回答。这些回答由 "do" 或 "does" 助动词所构成。例如:
Do you have to work on Saturday?(你周六得工作吗?)
Yes, I do.(是的)
Does he have to go to work by bus?(他得搭公共汽车去上班吗?)
Yes, he does.(是的)
然而,我们也可以包括一个原因在答复内,看这些例子:
Do you have to work on Saturday?(你周六得工作吗?)
Yes, I do. I have to finish this report.(是的,我得完成这份报告)
Does he have to go to work by bus?(他得搭公共汽车去上班吗?)
Yes, he does. He doesn't have a car.(是的,他没有车)
Do I have to wear a uniform?(我得穿制服吗?)
