题型：不详难度：来源：

The survey __________ our school last month shows that about 2 percent of the students are addicted to Internet games.

A．conducted

B．having been conducted

C．conducting

D．to be conducted

答案

A

解析

动词conduct与主语the survey之间存在着动宾关系，所以需用被动形式，依据last month可知，该动作发生在过去，排除CD。而B项答案不能作定语。conducted在此作定语，相当于which was conducted。
