根据句意可知，如果一位男士为了买一只猫使得自己和2.单选题In general, our society is becoming one of giant enterprises directed by a bureaucratic （官僚主义的）management in which man becomes a small, well-oiled cog in the machinery.The oiling is done with higher wages, well-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 or interest in 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 salaiy 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 subniissiveness and independence.From the moment on they arc 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 are never solved by returning to a stage which one has already outgrown.I suggest transforming our social system from a bureaucratically managed industrialism in which maximal 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.1.By "a well-oiled cog in the machinery" the author intends to deliver the idea that man is（）.2.The real cause of the anxiety of the workers and employees is that（）.3.From the passage we can conclude that real happiness of life belongs to those（）.4.To solve the present social problems the author puts forward a suggestion that we should （）.5.The author's attitude towards industrialism might best be summarized as one of（）. 问题1选项B.working in complete harmony with the rest of the societyC.an unimportant part in comparison with the rest of the societyD.a humble component of the society, especially when working smoothly问题2选项A.they are likely to lose their jobsB.they have no genuine satisfaction or interest in lifeC.they are faced with the fundamental realities of human existenceD.they are deprived of their individuality and independence问题3选项A.who could keep far away from this competitive worldB.who are higher up in their social statusC.who prove better than their fellow-competitorsD.who are at the bottom of the society问题4选项A.resort to the production mode of our ancestorsB.offer higher wages to the workers and employeesC.enable man to fully develop his potentialitiesD.take the fundamental realities for grantedA.approvalB.dissatisfactionC.suspicionD.susceptibility【答案】第1题:C第2题:D第3题:A第4题:C第5题:B【解析】1.判断推理题。

2.问答题Hurricanes, house fires, cancer, white-water rafting accidents, plane crashes, vicious attacks in dark archways. Nobody asks for any of it. But to their surprise, many people find that enduring such an ordeal ultimately changes them for the better. Their opinion might be something like this: “I wish it hadn’t happened, but I’m a better person for it.”reports of disaster; there is a built—in human capacity to flourish under the most difficult circumstances. Positive reactions to profoundly disturbing experiences are not limited to the toughest or the bravest. In fact, roughly half of the people who struggle with adversity say that their lives have in some ways improved.In a dark room in Queens, New York, 31-year-old fashion designer Tracy Cyr believed she was dying. A few months before, she had stopped taking the powerful immune-suppressing drugs that kept her arthritis（2） check. She never anticipated what would happen: a withdrawal reaction that eventually left her in total body agony and neurological meltdown. The slightest movement-trying to swallow, for example- was excruciating. Even the pressure of her check on the pillow was almost unbearable.Cyr is no wimp-diagnosed with juvenile rheumatoid arthritis at the age of two, she’d endured the symptoms and the treatments (drugs, surgery) her whole life. But this time, she was way past her limits, and nothing her doctors did seemed to help. Either the disease was going to kill her or, pretty soon, she’d have to kill herself.As her sleepless nights wore on, though, her suicidal thoughts began to be interrupted by new feelings of gratitude. She was still in agony, but a new consciousness grew stronger each night: an awesome sense of liberation, combined with an all-encompassing feeling of sympathy and compassion. “I felt stripped（3）everything I’d ever identified myself with,” she said six months later. “Everything I thought I’d known or believed in was useless-time, money, self-image, perception that was so forcing.”Within a few months, she began to be able to move more freely, thanks to a cocktail of steroids and other drugs. But as her physical strength came back, she did not return to her old way of being as a feisty, demanding “sex-in-the-City, three-inch-stilettos-and-fishnets” girl. Now quieter and more tolerant, she makes a point of being submissive in a tum-the-other cheek kind of way. Cyr still takes a pharmacopoeia of drugs every day, but she says there’s no question that her life is better now. “I felt I had been shown the secret of life and why we’re here, to be happy and to nurture other life. It’s that simple.”Her mind-blowing experience came as a total surprise. But that feeling of transformation is in some ways typical, says Rich Tedeschi, a professor of psychology at the University of North Carolina in Charlotte who coined the term “post-traumatic growth”，His studies of people who have endured extreme events like combat, violent crime or sudden serious illness show that most feel dazed and anxious in the immediate aftermath. They are preoccupied with the idea that their lives have been shattered. A few people are haunted long afterward by memory problems, sleep trouble and similar symptoms of post-traumatic stress disorder. But Tedeschi and others have found that for many people—perhaps even the majority life ultimately becomes richer and more gratifying.Something similar happens to many people who experience a terrifying physical threat. In that moment, our sense of invulnerability is pierced, and the self-protective mental armor that normally stands between us and our perceptions of the world is tom away. Our everyday life scripts---our habits, self-perceptions and assumptions-go out the window, and we’re left with a raw experience of the world.Still, actually implementing these changes, as well as fully coming to terms（4）the new reality, usually takes conscious effort. Being willing and able to take on this process isEventually, they may find themselves freed in ways they never imagined. Survivors often say they become more tolerant and forgiving（5）others, capable of bringing peace to formerly troubled relationships. They say that material ambitions suddenly seemed silly and the pleasures of friends and family became paramount-and that the crisis allowed them to reorganize life in line with the new priorities. People who have grown（6）adversity often feel much less fear, despite the frightening things they’ve been through. They are surprised by their own strength, confident that they can handle whatever else life throws at them. “People don’t say that what they went through was won derful,n says Tedeschi. “They weren’t meaning to grow from it. They were just trying to survive. But in retrospect, what they gained was more than they even anticipated.”In his recent book Satisfaction, Emory University psychiatrist Gregory Bens points to extreme endurance athletes who push themselves to their physical limits for days at a time. They cycle through the same sequence of sensations as do trauma survivors; self-loss, confusion and, finally, a new sense of mastery. For ultramarathoners, who regularly run 100-mile races that last more than 24 hours, vomiting and hallucinating are normal. After a day and night of running without stopping or sleeping, competitors sometimes forget who they are and what they’re doing.But the feeling of mastering extraordinary difficulty makes up for it, reports Honolulu businessman Randy Havre. Havre, 51, found this feeling near the summit of Mauna Kea nearly 10 years ago. He was nearing the end of a 44-mile race that took him from sea level to the top of the volcano-a vertical ascent of 13,766 feet. He was on his way to setting the unofficial world record for the climb, but the high elevation was starting to get（7） him.“When you get to about 10,000 feet, things tend to get a little weird because of the swelling a nd pressure on your brain,” he says. “Above that, it gets exponentially weirder. I remember busting out crying at 12,000 feet. But if you can finish these things, you know; Hey, I can get through this stuff. You were able to hang（8）there, and you’re stronger for that.”The emotional reward can compensate for the pain and difficulty of adversity. This perspective does not cancel（9）what happened, but it puts it all in a different context: that it’s possible to live an extraordinarily rewarding life even within the constraints and struggles we face. In some form or other, says King, we all must go（10）this realization. “You’re not going to be the person you thought you were, but here’s who you are going to be instead- and that turns out to be a pretty g reat life.”Fill in each blank in the article with an appropriate preposition (介词).Read the article carefully and explain the meaning of the words according to the context. tribulations (in paragraph 2)adversity (in paragraph 2)withdrawal (in paragraph 3)excruciating (in paragraph 3)wimp (in paragraph 4)aftermath (in paragraph 7)gratifying (in paragraph 7)exponentially (in paragraph 14)According to Rich Tedeschi, a professor of psychology at the University North Carolina in Charlotte, there is a phenomenon called “post-trauma growth”.

Fantasies of great wealth often involve visions of fancy cars and extravagant homes.Yet satisfaction with these material purchases wears off fairly quickly what was once exciting and new becomes old-hat;regret creeps in.It is far better to spend money onexperiences,say Ms Dumn and Mr Norton,like interesting trips,unique meals or even going to the cinema.These purchases often become more valuable with time-as stories or memories-particularly if they involve feeling more connected to others.This slim volume is packed with tips to help wage slaves as well as lottery winners get the most"happiness bang for your buck."It seems most people would be better off if they could shorten their commutes to work,spend more time with friends and family and less of it watching television(something the average American spends a whopping two months a year doing,and is hardly jollier for it).Buying gifts or giving to charity is often more pleasurable than purchasing things for oneself,and luxuries are most enjoyable when they are consumed sparingly.This is apparently the reason MacDonald's restricts the availability of its popular McRib-a marketing trick that has turned the pork sandwich into an object of obsession.Readers of“HappyMoney”are clearly a privileged lot,anxious about fulfillment,not hunger.Money may not quite buy happiness,but people in wealthier countries are generally happier than those in poor ones.Yet the link between feeling good and spending money on others can be seen among rich and poor people around the world,and scarcity enhances the pleasure of most things for most people.Not everyone will agree with the authors’policy ideas,which range from mandating more holiday time to reducing tax incentives for American homebuyers. But most people will come away from this book believing it was moneywell spent。

2.单选题Mutualism is a type of symbiosis that occurs when two unlike organisms live together in a state that is mutually beneficial. It can exist between two animals, between two plants, or between a plant and an animal. Mutualism is unlike the symbiotic state of commensalism in that commensalism is a one-sided state in which a host gives and a guest takes, while in mutualism both partners live on a give-and-take basis.In the African wilds, the zebra and the ostrich enjoy a symbiotic relationship that enhances the ability of these large land animals to survive. Both serve as prey for the lion, and neither has the capability alone to withstand an attack from this fierce hunter. However, when the zebra and the ostrich collaborate in their defense by alerting each other to possible danger from an approaching predator, the lion is rarely able to capture more than the oldest or feeblest of the herd. The complementary physical strengths and weaknesses of the ostrich and the zebra allow them to work in coordination to avoid succumbing to the lion. The ostrich, the largest flightless bird in the world, possesses great speed and keen eyesight, which enable it to spot large predatory animals long before they are able to position themselves to attack. The zebra, with a running speed equal to that of the ostrich, has excellent hearing and a good sense of smell but lacks the sharp eyesight of the ostrich. When ostriches and zebra intermix for grazing, each animal benefits from the ability of the other to detect approaching danger. If either animal senses danger, both animals are alerted and take off. With the running speed that both of these animals possess, they are able to outrun any predator except the cheetah.1.Choose the drawing that describes a commensalist state.2.The difference between mutualism and commensalism is that（）.3.In paragraph 2, the Word "that" refers to（）.4.Which of the following drawing describes what happens when a lion approaches a zebra and an ostrich?5.From the passage, we can learn that（）.问题1选项A.B.C.问题2选项mensalism is a two-sided state.B.the partners live on a give-and-take basis in mutualism.C.the host gives while the guest takes in mutualism.D.mutualism occurs between two similar organisms; however, commensalism, two unlike organisms.问题3选项A.running speedB.strengthC.weaknessD.eyesight问题4选项A.B.C.D.问题5选项A.the zebra often offers more help than the ostrich to detect the attack of the lion.B.the zebra and the ostrich are complementary in their abilities of avoiding being attacked byC.both the zebra and the ostrich possess great speed and keen eyesight.D.with great speed, the zebra and the ostrich run faster than any predator.【答案】第1题:B第2题:B第3题:A第4题:D第5题:B【解析】1.细节事实题。
