Question

---I don’t think sixteen-year-olds _______ to drive.

---I agree. They aren’t serious enough at that age.

A. can allow             B. need be allowed

C. should allow           D. should be allowed

Answer

D

【解析】

试题分析：句意：――我认为不应该允许十六岁的人开车。――我同意，在那个年龄他们还不够严肃。“允许十六岁的人开车”，sixteen-year-olds作主语，用被动语态。A、C都是主动语态，错了。带有情态动词的被动语态，由情态动词+be+及物动词的过去分词构成。B need be allowed, 需要被允许；D should be allowed应该被允许，根据句义，正确选D。

考点：考查动词时态及语态辨析。
