问题 Which of the following sentences expresses probability?

选项 A、He must have picked up a cold—he’s begun to snuffle.
B、We must have a clear understanding of the problem.
C、One must have one’s own opinions and not drift with the current.
D、To be healthy one must have an adequate diet.

答案 A

解析 情态动词题。情态动词must除了用来表示命令,必须如何以外,还可表示有依据的肯定推测,意为“一定会……”,对现在情况的推测用“must+动词原形”;对已经发生的情况的推测则用“must have done”。[B]、[C]以及[D]中的must have都表示“必须要有……”;[A]意为“他开始鼻塞,一定是感冒了。”因此[A]为答案。
