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 multiuser 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)。通過預讀選項可知，本題與電腦病毒有關。應遵循短文聽力聽首尾的原則，文章一開始就明確了說明對象是computer virus。本題考查該名稱的由來，但文中是以原因的形式出現的：The cause of the term "computer virus" is the likeness between the biological virus and the evil program infected with computers，A)的說法正是該定義的簡短描述。其中，resemble是"...與...相似的"意思，而文中的說法是the likeness between...and...，二者是一致的。
33. What is the way that the computer viruses infect the computer systems?
B)。分析選項可知，本題考查電腦病毒的工作方式。由于其特殊性，可遵循"聽到即是解"的原則解題。文章先介紹了人類病毒的工作方式，然后用一個however引出了本題的答案：computer viruses are small programs. They expand by attaching a copy of themselves to another program。
34. What is a "benign" virus?
D)。預讀選項可知，本題與一種電腦病毒有關。題目中的benign是關鍵詞，由此可以很容易定位到：So called "benign" or the harmless viruses might simply display a message...，可見本題的答案是以同位語的形式出現的，所謂"良性"病毒就是D)所說的不會造成危害的病毒。
35. What can a "malignant" virus do to your computer?
B)。預讀選項可知，本題仍然與一種電腦病毒有關。由于上一道題目考查了"良性"病毒，根據常識可以推斷本題定然會考查與之相對應的"惡性"病毒的危害。聽錄音時的關鍵詞是malignant，由此可以很容易定位到：Malignant or the harmful viruses are designed to damage the system，這正是B)的同義表達。
Section C
36. outline
[點撥]空格前是and，and前后成分相同，所以空格處為動詞原形。根據句意推測：宇宙未來可以預測，但這并不意味著單單坐著就肯定能夠概括宇宙未來的發展過程。
37. certainty
[點撥]空格前是anything like，后面應該為名詞。由36題的分析，可以推出這里表示"一定，肯定"的意思。
38. exactly
[點撥]空格前是動詞know，后面是賓語，可見中間缺一副詞來修飾know。根據前后文可以推測：我們不清楚宇宙的構成，但卻十分清楚我們的知識領域缺乏什么信息。
39. idea
[點撥]空格前是a good，可見空格處為名詞。根據38題分析，接下來的句意應該是：我們也清楚地知道如何得到這些信息。
40. imagine
[點撥]空格前是不定式to，可見空格處為動詞原形。根據句意推測：我們考慮目前形勢的最佳方式就是假想一輛進站的火車。
41. determined
[點撥]空格前是is completely，可知空格處為動詞的過去分詞。根據句意，火車進站前所有的開關都設定好了，我們可以推測：它前進的路就完全確定了。
42. possible
[點撥]空格前是some，后為futures，可以確定空格處是一形容詞。前后句連起來的意思為：如果能看清開關的設置，就可以肯定有些未來是不能實現的，而其余的能夠實現。
