Question

many new houses in this

---So far this year，many new houses in this area with the help of the government．---It’s great．（　　）
A. build
B. are built
C. will build
D. have been built

Answer 1

答案：D
首先根据时间状语so far this year，判断用现在完成时，主语many new houses是动作build的承受者，所以用被动语态，现在完成时被动语态的构成是：主语+have/has been+动词的过去分词，主语是复数名词，助动词用have，build的过去分词是built，故选D．
