(单选题)

Which of the following sentences express “probability”?

A.He must complete the work tonight.

B.All visitors must report to the reception.

C.He must have lost his way.

D.You simply must read this book.

参考答案：C

参考解析：

考查情态动词表推测。句意：下面哪一个句子表达“可能”？He must complete the work tonight意为“他今晚必须完成这项工作”；All visitors must report to the reception意为“所有来访者必须到接待处报到”；He must have lost his way意为“他一定/肯定是迷路了”；You simply must read this book意为“你必须要读读这本书”。“must”一词有三层含义，一是“（主观看法上）必须”，二是“（肯定的可能性推测）一定，肯定”，三是“偏要，硬要”。must have done表示对过去发生事情的肯定推测，且强调发生的可能性较大。故选C。
