— There are more and more Internet crimes.
— ___________________.

选择一项：
A. It has nothing to do with me.
B. It.s none of your business.
C. I think we should introduce more regulations to supervise the Internet.

C. I think we should introduce more regulations to supervise the Internet.解析：本题考核“表达意见”。第一说话人说到现在出现越来越多的网络犯罪，第二说话人就这一事件发表自己的意见，觉得应该引入更多监管的条例，选项“It's none of your business.”和选项“It has nothing to do with me.”违反交际用语里的礼貌用语原则，所以答案是“I think we should introduce more regulations to supervise the Internet.”。
