单项选择题
According to some scientists, the computer will do much harm to people's health as smoking and drugs do.
A．does much harm...smoking
B．will do as much harm...cigarettes
C．will do so much harm...smoking
D．does as much harm...cigarettes
答案
参考答案：B
解析：[分析]结构应用 本句考察的是比较级中的同等比较，用as...as...句型；此处will表示推测，另外后一个 as后面连接了两个并列的词，应该共形，因此将smoking改为cigarettes；因此答案为B。
