单选题 Being sociable looks like a good way to add years to your life. Relationships with family, friends, neighbours, even pets, will all do the trick, but the biggest longevity (长寿) boost seems to come from marriage or an equivalent relationship. The effect was first noted in 1858 by William Farr, who wrote that widows and widowers (鳏夫) were at a much higher risk of dying than their married peers. Studies since then suggest that marriage could add as much as seven years to a man's life and two to a woman's. The effect holds for all causes of death, whether illness, accident or self-harm. Even if the odds are stacked against you, marriage can more than compensate. Linda Waite of the University of Chicago has found that a married older man with heart disease can expect to live nearly four years longer than an unmarried man with a healthy heart. Likewise, a married man who smokes more than a pack a day is likely to live as long as a divorced man who doesn't smoke. There's a flip side, however, as partners are more likely to become ill or die in the couple of years following their spouse's death, and caring for a spouse with mental disorder can leave you with some of the same severe problems. Even so, the odds favour marriage. In a 30-year study of more than 10,000 people, Nicholas Christakis of Harvard Medical School describes how all kinds of social networks have similar effects. So how does it work? The effects are complex, affected by socio-economic factors, health-service provision, emotional support and other more physiological (生理的) mechanisms. For example, social contact can boost development of the brain and immune system, leading to better health and less chance of depression later in life. People in supportive relationships may handle stress better. Then there are the psychological benefits of a supportive partner.

单选题In Shanghai, a growing number of foreign-funded banks are looking for local people to fill executive positions (行政主管的岗位) rather than people from their own countries as they did in the past. US-based Citibank (花旗银行) put a job announcement in a local newspaper last week calling for executive trainees. It was part of Citibank"s business plan in China to draw local professional. Demand for personal banking services has been on the rise since China joined the World Trade Organization at the end of 2001. Thence, more employees are needed in the banks. The move does not only happen to Citibank. Many other foreign-funded banks in the city have made similar decisions. The UK"s Standard Chartered last year employed over 30 graduates from Chinese universities and colleges as executive trainees. They are expected to take up managerial positions at the bank"s Shanghai branch after a two-year raining program overseas. The Hong Kong and Shanghai Banking Corporation has announced it will employ more new graduates in China in the coming year. Local people account for over 92% of the office workers in its Shanghai operation.

单选题The entertainment profession, or "show business", attracts many young people. Unfortunately, only very few can hope to become famous. Talent is not enough, because show business is as competitive as any other business. Without a good manager, a performer can never hope to succeed. Fashion is important in this business too. A performer must change their "act" in order to follow the taste of the moment. This is true for actors, dancers and comedians, but perhaps most of all for singers. "Pop" stands for "popular", and a singer has to work very hard to become popular. They must either give the public what they want, or they must find a new way of singing that will attract their attention. Even when they have succeeded, and their records are sold everywhere, they can not relax. Then they must work harder than ever to remain popular, because there are always younger singers trying to become famous and to steal some of the popularity. The life of a successful pop singer is not at all easy. They can only relax when they are alone, because everything they do is watched and reported in the special newspapers written for the "fans". The fans are the most important people in the world for the singers. They buy their records, they go to their concerts, and they make them rich and famous. But they can be very annoying too. Sometimes they get so crazy that they do anything to get a "souvenir". They steal handkerchiefs, they tear off buttons, and they even cut off pieces of the unfortunate singer"s hair. Many singers have been forced to hide, and some who have not been so lucky as to escape have been stripped practically naked by their fans. Pop singers have to spend a lot of money on clothes, because they must always look smart, or, at any rate, different. They must have a luxurious car. And most important they must always keep smiling for the benefit of his public.

单选题The chairman was blamed for letting his secretary ______ too much work last week.

单选题 (C) It is pretty much a one-way street. While it may be common for university researchers to try their luck in the commercial world, there is very little traffic in the opposite direction. Pay has always been the biggest deterrent, as people with families often feel they cannot afford the drop in salary when moving to a university job. For some industrial scientists, however, the attractions of academia (学术界) outweigh any financial considerations. Helen Lee took a 70% cut in salary when she moved from a senior post in Abbott Laboratories to a medical department at the University of Cambridge. Her main reason for returning to academia mid-career was to take advantage of the greater freedom to choose research questions. Some areas of inquiry have few prospects of a commercial return, and Lee's is one of them. The impact of a salary cut is probably less severe for a scientist in the early stages of a career. Guy Grant, now a research associate at the Unilever Centre for Molecular Informatics at the University of Cambridge, spent two years working for a pharmaceutical (制药的) company before returning to university as a post-doctoral researcher. He took a 30% salary cut but felt it worthwhile for the greater intellectual opportunities. Higher up the ladder, where a pay cut is usually more significant, the demand for scientists with a wealth of experience in industry is forcing universities to make the transition (转换) to academia more attractive, according to Lee. Industrial scientists tend to receive training that academics do not, such as how to build a multidisciplinary team, manage budgets and negotiate contracts. They are also well placed to bring something extra to the teaching side of an academic role that will help students get a job when they graduate, says Lee, perhaps experience in manufacturing practice or product development. "Only a small number of undergraduates will continue in an academic career. So someone leaving university who already has the skills needed to work in an industrial lab has far more potential in the job market than someone who has spent all their time on a narrow research project."

单选题Most of us grow up taking certain things for granted. We tend to assume that experts and religious leaders tell us "the truth". We tend to believe that things advertised on television or in newspapers can"t be bad for us. However, encouragement of critical thinking in students is one of the goals of most colleges and universities. Few professors require students to share the professors" own beliefs. In general, professors are more concerned that students learn to question and critically examine the arguments of others, including some of their own beliefs or values. This does not mean that professors insist that you change your beliefs, either. It does mean, however, that professors will usually ask you to support the views you express in class or in your writing. If your premises (前提) are shaky, or if your arguments are not logical, professors personally point out the false reasoning in your arguments. Most professors want you to learn to recognize the premises of your arguments, to examine whether you really accept these premises, and to understand whether or not you draw logical conclusions. Put it this way: Professors don"t tell you what to think; they try to teach you how to think. On the other hand, if you intend to disagree with your professors in class, you should be prepared to offer a strong argument in support of your ideas. Arguing just for the sake of arguing usually does not promote a critical examination of ideas. Many professors interpret it as rudeness.

单选题John had bought a packet of cigarettes just before we caught the train and he offered me one as we settled ourselves in our compartment. We were on our way back from a camping holiday. We had lived rough for over a fortnight and even a cigarette was a luxury at that moment. I felt in my pocket for a box of matches, but could not find any. "I haven"t got any either," said John. Sitting opposite to us was a man whose face was hidden by a newspaper. "Excuse me, sir," said John, leaning across. " Could you give me a light, please?" The newspaper was lowered to reveal a rather elderly man with a stern face. "This is a no smoking compartment," the man said. He indicated the notice near the window. We apologized and put away our unlit cigarettes. The man went on, in a rather more kindly way, to warn us against the dangers of smoking. "I speak as a doctor," he concluded, and after that he went back to reading his newspaper. When he got out a few stations later, he left his newspaper behind him. We picked it up, eager to find out what had happened while we were on holiday. "Just look at this," remarked John, pointing to a photograph. "it"s the man who was sitting opposite us." Underneath the photograph was an account of a lunatic (精神病者) who had recently escaped. It appeared that he liked to pretend to be a doctor.
