Question

【题目】—It’s difficult for the village children to cross the river for school.

—I think a bridge over the river.

A. was built B. should be bulit C. has been built

Answer 1

【答案】B

【解析】句意：-对于村子里的孩子们来说过河去上学是非常困难的。-我认为在河上应该修一座桥。was built被修，一般过去时的被动语态；should be built应该被修；has been built现在完成时的被动语态，已经被修。三个选项都使用了被动语态，根据句意可知，河面上还没有修建桥，故A和C时态都不对，B选项符合句意，故选B。
