【题目】What an important role the Internet _____ in our life! One can hardly imagine ____ life would be like without it.
A. plays, how B. is, however
C. uses, what D. plays, what
在线课程【答案】D
【解析】
试题分析：固定短语：play a role in “在……中起作用”；imagine后的宾语从句缺少介词like的宾语，所以用疑问代词，故答案选D。句意：因特网在我们生活中起着多么重要的作用啊！人们几乎想象不到没有了网络生活会是什么样子。
