问题 Which of the following sentences expresses a fact?

选项 A、Mary and her son must be home by now.
B、Careless reading must give poor results.
C、He must be working late at the office.
D、It’s getting late, and I must leave now.

答案 B

解析 情态动词题。情态动词must可表示“必须,必要”等,选项[D]“天色晚了,我必须得走了”符合此意,排除;must也可以表示肯定性推测,选项[A]“玛丽和她儿子现在应该到家了”和选项[C]“他肯定在办公室工作到很晚”,均符合此意,排除。must在特殊语境下,还可以表示对某种事实的强调,因此选项[B]“阅读不仔细必然会有差结果”为答案。
