听力原文:Internet use appears to cause a decline in psychological well-being, according to

听力原文: Internet use appears to cause a decline in psychological well-being, according to research at Carnegie Mellon University.

Even people who spent just a few hour's a week on the Internet experienced more depression and loneliness than those who logged on less frequently, the two-year study showed. And it wasn't that people who were already feeling bad spent more time on the Internet, but that using the Net actually appeared to cause the bad feelings.

Researchers are puzzling over the results, which were completely contrary to their expectations. They expected that the Net would prove socially healthier than television, since the Net allows users to choose their information and to communicate with others.

The fact that Internet use reduces time available for family and friends may account for the drop in well-being, researchers hypothesized.

Faceless, bodiless "virtual" communication may be less psychologically satisfying than actual conversation, and the relationships formed through it may be shallower. Another possibility is that exposure to the wider world via the Net makes users less satisfied with their lives.

"But it's important to remember this is not about the technology; it's about how it is used," says psychologist Christine Riley of Intel, one of the study's sponsors. "It really points to the need for considering social factors in terms of how you design applications and services for technology."

(33)

A.People who feel bad spent more time on the Internet.

B.Using internet can cause depression and loneliness.

C.Internet use can improve psychological well-being.

D.Surfing Net for a few hours a week cannot cause bad feelings.

Questions 下列各are based on the following passage. The "paperless office" has earned a pr
oud place on lists of technological promises that did not come to pass. Surely, though, the more modest goal of he carbon-paperless office is within the reach of mankind? Carbon paper allows two copies of a document to be made at once. Nowadays, a couple of keystrokes can do the same thing with a lot less fuss. Yet carbon paper persists. Forms still need to be filled out in a way that produces copies. This should not come as a surprise. Innovation tends to create new niches(合适的职业), rather than refill those that already exist. So technologies may become marginal, but they rarely go extinct. And today the little niches in which old technologies take refuge are ever more viable and accessible, thanks to the Internet and the fact that production no longer needs to be so mass; making small numbers of obscure items is growing easier. On top of that, a widespread technostalgia(技术怀旧 ) seeks to preserve all the ways people have ever done anything, simply because they are kind of neat. As a result technologies from all the way back to the stone age persist and even flourish in the modern world. According to What Technology Wants, a book by Kevin Kelly, one of the founders of Wired magazine, Americas flintknappers (燧石) produce over a million new arrow and spear heads every year. One of the things technology wants, it seems, is to survive. Carbon paper, to the extent that it may have a desire for self-preservation, may also take comfort in the fact that, for all that this is a digital age, many similar products are hanging on, and even making comebacks. Indeed, digital technologies may prove to be more transient than their predecessors. They are based on the idea that the medium on which a files constituent 0s and 1s are stored doesnt matter, and on Alan Turings insight that any computer can mimic any other, given memory enough and time. This suggests that new digital technologies should be able to wipe out their predecessors completely. And early digital technologies do seem to be vanishing. The music cassette is enjoying a little renaissance, its very faithlessness apparently part of its charm; but digital audio tape seems doomed. So revolutionary digital technologies may yet discard older ones to the dustbin. Perhaps this will be the case with a remarkable breakthrough in molecular(分子的) technology that could, in principle, store all the data ever recorded in a device that could fit in the back of a van. In this instance, it would not be a matter of the new extinguishing the old. Though it may never have been used for MP3s and PDFs before, DNA has been storing data for over three billion years. And it shows no sign of going extinct. Which of the following is TRUE about the carbon paper?

A.It is the key to paperless office.

B.It will be replaced by the computer soon.

C.It is more troublesome than the computer.

D.It can hardly survive in the digital age.

第6题
In general, our society is becoming one of giant enterprises directed by a bureaucratic m
anagement in which man becomes a small, well-oiled cog in the machinery. The oiling is done with higher wages, Nell-ventilated factories and piped music, and by psychologists and “human-relations” experts; yet all this oiling does not alter the fact that man has become powerless, that he is bored with it. In fact, the blue and the white-collar workers have become economic puppets who dance to the tune of automated machines and bureaucratic management.

The worker and employee are anxious, not only because they might find themselves out of a job; they are anxious also because they are unable to acquire any real satisfaction of interesting life. They live and die without ever having confronted the fundamental realities of human existence as emotionally and intellectually independent and productive human beings.

Those higher up on the social ladder are no less anxious. Their lives are no less empty than those of their subordinates. They are even more insecure in some respects. They are in a highly competitive race. To be promoted or to fall behind is not a matter of salary but even more a matter of self-respect. When they apply for their first job, they are tested for intelligence as well as for the right mixture of submissiveness and independence. From the moment on they are tested again and again-by the psychologists, for whom testing is a big business, and by their superiors, who judge their behavior, sociability, capacity to get along, etc. This constant need to prove that one is as good as or better than one ’s fellow-competitor creates constant anxiety and stress, the very causes of unhappiness and illness.

Am I suggesting that we should return to the preindustrial mode of production or to nineteenth-century “free enterprise” capitalism? Certainly not.Problems the never solved by returning to a stage which one has already outgrown. I suggest transforming our social system form, a bureaucratically managed industrialism in which maxima, production and consumption are ends in themselves, into a humanist industrialism in which man and full development of his potentialities-those of all love and of reason-are the aims of social arrangements. Production and consumption should serve only as means to this end and should be prevented from ruling man.

By “a well-oiled cog in the machinery ” the author intends to deliver the idea that man is ____.

A.a necessary part of the society though each individual ’s function is negligible

B.working in complete harmony with the rest of the society

C.an unimportant part in comparison with the rest of the society

D.a humble component of the society, especially when working smoothly

The real cause of the anxiety of the workers and employees is that ____.A.they are likely to lose their jobs

B.they have no genuine satisfaction or interest in life

C.they are faced with the fundamental realities of human existence

D.they are deprived of their individuality and independence

From the passage we can conclude that real happiness of life belongs to those ____.A.who are at the bottom of the society

B.who are higher up in their social status

C.who prove better than their fellow-competitors

D.who could dip fir away from this competitive world

To solve the present social problems the author puts forward a suggestion that we should ____.A.resort to the production mode of our ancestors

B.offer higher wages to the workers and employees

C.enable man to fully develop his potentialities

D.take the fundamental realities for granted

The author’s attitude towards industrialism might best be summarized as one of ____.A.approval

B.dissatisfaction

C.suspicion

D.susceptibility
