　　Passage One
　　Questions 57 to 61 are based on the following passage.
　　It is 4 o’clock in the early morning.Everything but the computing room on the campus of the university appears as quiet and misty as the mysterious hell. In the computing room, 30 students crumpled with blurred eyes, sit still at their desk, thumping the dirty and worn keys. Staring at the colorful screen, they tap continuously for hours. For the other parts in the world, it might be in the midst of the night, nevertheless here time represents nothing. It is an utterly enclosed field. These young computer "hackers" are tracing a sort of stimulus; a drive so exciting and absorbing it downplays nearly anything else in their lives and founds as the focus their being. They are compelled computer programmers. Some of these students have been glued to the console for no less than twenty hours even with no break for meals or rest. Some have been sleeping on sofas and lounge chairs in the computing room, trying to struggle for a few moments’rest but hate to get too far away from their addicted machines.
　　It is no necessary for most of these students to be at the computing room in the middle of the night. What they are working belong to no assignments. They remain there because they desire to be-they can not resist the attraction of the computers.
　　Furthermore they are in groups instead of alone. There are hackers at computing rooms all over the country. In the unimaginable way, they focus on nothing but computer. They escape from schooling and live beyond friendship; they might have difficulty being employed, choosing to travel from one computing room to another. They may even abandon personal health.
　　"There is one hacker in my memory. We actually had to lift him away from his chair to feed him and arrange him to rest and sleep. We truly worried about his health," says a computing science professor at California University.
　　Professors of computer science are nowadays shedding more light on this hacker phenomenon and are on the watch for latent hackers and more and more severe computer addictives. They are sober that hackers are not simply resulted from the close relationship with a machine. It is the result of social relationship with the attractive thinking machines, which are becoming nearly universal.

　　Questions 62 to 66 are based on the following passage.
　　Very few commenters have a better point of that forbidding exchanging media called E-mail than John Moon, the CEO of E-mail management company Talk Labs. Moon examines a network that deals with 5.0 million letters everyday. The servers run and fixed by Talk Labs manage mail delivery and routing for many companies, including Security Company of England and Malshef Business.
　　As a matter of fact, all of Talk Labs’customers are madeup of companies whose daily E-mail outflow and inflow have substantially increased with the expansion of the Web. "E-mail usage has significantly risen recently," he says. Indeed, Talk Labs estimates that it has risen from 20 a day each employee as lately as three years ago to 30 or 40 at present.
　　The implications for Corporate America are equally huge. As E-mail researcher and consultant Jack Blour believes, companies can be in the expectation of the volume of E-mail rising through their servers to grow 70% to 90% in 2002. And as individual messages soar it is most likely that they contain memory-companies could finally pay 100% to 150% more simply this year on systems in the store and management of those messages. That’s the reason why tech consultancy Tadigul Group predicts demand for software manageing E-mail, such as Microsoft Outlook and Lotus Notes, to grow from $2.6 billion in sales today to $4.4 billion by 2005.
　　Controlling pure junk will cost too much money. About 20% of the E-mail Talk Labs manages is uninvited, according to Moon-who further states that about 1.25% of all the E-mail his company cancels includes useless files.
　　It is estimated that handling spam（垃圾邮件） costs $8.6 billion throughout the world, according to a 2001 Japanese study. And some companies has been worried that the jam of pornographic spam may urge employees to sue on grounds of disturbance due to brought discomfort.
