三、新课导引





SECTION A

1.It must be Carla’s.它一定是卡拉的。

must be“一定是”。情态动词must除表示“必须”外,还表示推断,通常与be连用,意为“一定是,肯定是”。must这种表示推测的用法只用于肯定句中。

There must be something wrong with the computer.那台电脑一定是出了什么毛病。

注意

(1)can't be意为“不可能是”,表示有把握的否定推测。

That man can't be Mr. Wang.He is ill in hospital.

那个人不可能是王先生,他生病住院了。

(2)含有must be的句子变为否定句时,需把must be改为can't be。

We must be wrong.我们一定是搞错了。(改为否定句)

We can't be wrong.我们不可能搞错了。
