问题补充:
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:
(答案→)A. conducted
B. having been conducted
C. conducting
D. to be conducted
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。
