【正确答案】 C

【答案解析】[听力原文]36-40 Cyber attacks are on the increase against home computer users largely because they have lower levels of security protection. That's according to Symantec Corporation that sells computer anti-virus software. Symantec's latest Internet Security Threat Report finds home users account for 86% of all targeted attacks followed by businesses that sell financial services. In addition, attackers are using a variety of techniques to escape detection and prolong their presence on your system. Symantec says there's one reason scammers are going after home computers. "And that's partially because of the data that contain credit card information, social security numbers, and partially because of the machines that control the high speed links which in turn can be used for spamming, and fraud". Symantec says attackers are using a variety of means to steal information and they get more sophisticated every day. "So we've already seen the attackers go from e-mail only to Web browsers. And now we are starting to see them using other techniques, such as instant messaging and phone calls." The company urges computer users to develop Internet streetsmarts and be skeptical of anyone online who asks them to divulge confidential information. [难点] 此题又是一道总结题。几个选项看似都有道理，但是仔细分析，还是第三个选项最具总结性，这篇文章讲的还是网络攻击入侵问题。

【答案解析】[难点] 此题主要考查数字。所以，考生一听到数字往往就要留心，培养敏感度。提炼出来不难得出答案是86%。

【正确答案】 D

【答案解析】[难点] 此题要看清题目，题目问的是哪一个选项“not”被提到。其他选项都明确提到过，只有最后一项，“家用电脑的保护不够”没有被提到成为家用电脑容易成为被攻击对象的原因。

【正确答案】 D

【答案解析】[难点] 此题又是推断题。不过其实只有运用一下理性思维就可以推断最后一项是不可能的。现在即时信息成为了一项重要的手段，不可能被取缔。

【正确答案】 B

【答案解析】[难点] 此题就算没听清楚也能推断出来。全文讲的是电脑入侵问题，那么这个公司生产的产品必定是解决这一问题的，所以最有可能是杀毒软件。
