Question

【题目】A lot of tall buildings in his hometown in the last three years.

A.have set upB.have been set upC.were set upD.set up

Answer 1

【答案】B

【解析】

句意：在最近三年里许多高大的建筑在他的家乡建立起来。

主语和动词之间是动宾关系，所以用被动语态：be +动词过去分词。in the last three years.在过去的三年里，是现在完成时的时间状语。所以该句用被动语态的现在完成时态：have/has+been+动词过去分词，主语是复数，故选B。
