  Passage Three
  The computer virus is an outcome of the computer overgrowth in the 1980s. (32)The cause of the term “computer virus” is the likeness between the biological virus and the evil program infected with computers. The origin of this term came from an American science fiction “The Adolescence of P-1” written by Thomas J. Ryan, published in 1977. Human viruses invade a living cell and turn it into a factory for manufacturing viruses. However, (33)computer viruses are small programs. They expand by attaching a copy of themselves to another program. Once attached to the host program, the viruses then look for other programs to “infect”. In this way, the virus can spread quickly throughout a hard disk or an entire organization when it infects a LAN or a multiuser system. The timing of the attack can be linked to a number of situations, including a certain time or date, the presence of a particular file, the security level of the user, and the number of times a file is used. Likewise, the mode of attack varies. (34)So called “benign” or the harmless viruses might simply display a message, like the one that infected IBM’s main computer system last Christmas with a season’s greeting. (35)Malignant or the harmful viruses are designed to damage the system. The attack is to wipe out data, to delete files, or to format the hard disk.
  32. How did the name of “computer virus” come into being?
  A)。通过预读选项可知,本题与电脑病毒有关。应遵循短文听力听首尾的原则,文章一开始就明确了说明对象是computer virus。本题考查该名称的由来,但文中是以原因的形式出现的:The cause of the term “computer virus” is the likeness between the biological virus and the evil program infected with computers,A)的说法正是该定义的简短描述。其中,resemble是“…与…相似的”意思,而文中的说法是the likeness between…and…,二者是一致的。
  33. What is the way that the computer viruses infect the computer systems?
  B)。分析选项可知,本题考查电脑病毒的工作方式。由于其特殊性,可遵循“听到即是解”的原则解题。文章先介绍了人类病毒的工作方式,然后用一个however引出了本题的答案:computer viruses are small programs. They expand by attaching a copy of themselves to another program。
  34. What is a “benign” virus?
  D)。预读选项可知,本题与一种电脑病毒有关。题目中的benign是关键词,由此可以很容易定位到:So called “benign” or the harmless viruses might simply display a message…,可见本题的答案是以同位语的形式出现的,所谓“良性”病毒就是D)所说的不会造成危害的病毒。
  35. What can a “malignant” virus do to your computer?
  B)。预读选项可知,本题仍然与一种电脑病毒有关。由于上一道题目考查了“良性”病毒,根据常识可以推断本题定然会考查与之相对应的“恶性”病毒的危害。听录音时的关键词是malignant,由此可以很容易定位到:Malignant or the harmful viruses are designed to damage the system,这正是B)的同义表达。
