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.

单选题I have made an ______ to see the doctor at 9 this morning.

单选题The workers" demands are ______; they are asking for only a small increase in their wages.

单选题In sports the sexes are separate. Women and men do not run or swim in the same races. Women are less strong than men. That at least is what people say. Women are called "the weaker sex", or, if men want to please them "the fair sex". But boys and girls are taught together at schools and universities. There are women who are famous Prime Ministers, scientists and writers. And women live longer than men. A European woman can expect to live until the age of 74, a man only until he is 68. Are women"s bodies really weaker? The fastest man can run a mile in under 4 minutes. The best women need 4.5 minutes. Women"s times are always slower than men"s, but some facts are a surprise. Some of the fastest women swimmers today are teenage girls. One of them swam 400 meters in 4 minutes 21.2 seconds when she was only 16. The first "Tarzan" in films was an Olympic swimmer, Johnny Weissmuller. His fastest 400 meters was 4 minutes 59.1 seconds, which is 37.9 seconds slower than a girl 50 years later! This does not mean that women are catching men up. Conditions are very different now, and sport is much more serious. It is so serious that somewomen athletes are given hormone injections. At the Olympics a doctor has to check whether the women athletes are really women or not. It seems sa.d that sport has problems. Life can be very complicated when there are two separate sexes!
