问题 From the first paragraph, we know ______ .
All the following are reasons for the rise in cyber crime EXCEPT ______ .
选项 A、victims won’t report intrusions by hackers
B、victims have no firewalls
C、the use of modem is increasing
D、companies don’t pay enough attention to security
答案B
解析 推断题。虽然文章提到了firewall(防火墙)，但并没有说公司不使用防火墙是网络犯罪率升高的原因，故选B。而文章第三段第三句(A项)，第二段倒数第二句(C项)和第三段第四句(D项)则分别说明了网络犯罪率上升的原因。
