Question

【题目】—It's difficult to get to the other side of the river.

—I think a bridge ________ over the river.

A. should be built B. should build

C. will build D. has built

Answer 1

【答案】A

【解析】

试题句意：--到河的对岸是困难的。--我认为一座桥应该被建立在河上。考查被动语态的用法，联系语境，表示应该被建立，因此运用情态动词should的被动语态。构成：should be done（动词过去分词）。故选A
