No clear-cut distinction can be drawn between professionals and amateurs in science: exceptions can be found to any rule. Nevertheless, the word "amateur" does carry a connotation that the person concerned is not fully integrated into the scientific community and, in particular, may not fully share its values. The growth of specialisation in the nineteenth century, with its consequent requirement of a longer, more complex training, implied greater problems for amateur participation in science. The trend was naturally most obvious in those areas of science based especially on a mathematical or laboratory training, and can be illustrated in terms of the development of geology in the United Kingdom. A comparison of British geological publications over the last century and a half reveals not simply an increasing emphasis on the primacy of research, but also a changing definition of what constitutes an acceptable research paper. Thus, in the nineteenth century, local geological studies represented worthwhile research in their own right; but, in the twentieth century, local studies have increasingly become acceptable to professionals only if they incorporate and reflect on the wider geo logical picture. Amateurs, on the other hand, have continued to pursue local studies in the old way. The overall result has been to make entrance to professional geological journals harder for amateurs, a result that has been reinforced by the wide spread introduction of refereeing, first by national journals in the nineteenth century and then by several local geological journals in the twentieth century. As a logical consequence of this development, separate journals have now appeared aimed mainly towards either professional or amateur readership. A rather similar process of differentiation has led to professional geologists coming together nationally within one or two specific societies, whereas the amateurs have tended either to remain in local societies or to come together nationally in a different way. Although the process of professionalisation and specialisation was already well under way in British geology during the nineteenth century, its full consequences were thus delayed until the twentieth century. In science generally, however, the nineteenth century must be reckoned as the crucial period for this change in the structure of science. The growth speeialisation in the 19th century might be more clearly seen in sciences such as ______. A．sociology and chemistry B．physics and psychology C．sociology and psychology D．physics and chemistry

We don't know what the effects would be on healthy human cells, Marinelli told New Scientist magazine. In the Italian study, after 24 hours 20 percent more leukemia cells died than healthy cells but longer exposure to the radio waves triggered genes in the surviving cancer cells to divide aggressively. The results of the study do not show any direct threat to human health but they support the belief of some scientists who say radiation can damage DNA and destroy the cell repair system, thus making tumors more deadly. But animal studies, including recent research by Australian scientists at the Institute of Medical and Veterinary Science in Adelaide, have shown that radiation from mobile phones does not trigger the growth of tumors. The WHO (i.e., The World Health Organization) has called for more research into the potential health hazards of mobile phones and has urged people to limit their use of them. A British government inquiry, which concluded that there was no evidence that mobile phones are a danger to health, has advised parents to discourage their children, whose brains are still developing, from using them excessively. What is the speaker's main topic？ A．Effects of using mobile phones on healthy human cells. B．Risks of developing cancer involved in the use of mobile phones. C．Damage to healthy cells caused by the use of mobile phones. D．The potential health hazards of mobile phones on humans.

Africans have some reasons to be cheerful. The continent's economy has been doing fairly well with South Africa, the economic powerhouse, growing steadily over the past few years. Some of Africa's long-running conflicts, such as the war between the north and south in Sudan and the civil war in Congo, have ended. Africa even has its first elected female head of state, in Liberia. Yet there is no shortage of downers too. Most of Africa remains dirt poor. Crises in places like Cote d'Ivoire, Sierra Leone and Zimbabwe are far from solved. And the democratic credentials of Ethiopia and Uganda, once the darlings of western donors, have taken a bad knock. AIDS killed over gm Africans in 2005, and will kill more this year. So is it all just a case of irrational exuberance？ Meril James of Gallup argues that there is, in fact, usually very little relation between the survey's optimism rankings and reality. Africans, this year led by Nigerians, are consistently the most upbeat, whether their lot gets better or not. On the other hand, Greece—hardly the worst place on earth—tops the gloom and doom chart, followed closely by Portugal and France. Ms James speculates that religion may have a lot to do with it. Nine out of ten Africans are religious, the highest proportion in the world. But cynics argue that most Africans believe that 2006 will be golden because things have been so bad that it is hard to imagine how they could possibly get worse. This may help explain why places that have suffered recent misfortunes, such as Kosovo and Afghanistan, rank among the top five optimists. Moussaka for thought for those depressed Greeks. The statistics are employed in the first paragraph so as to indicate sort of ______. A．disparity B．numbness C．conformity D．stagnation

Researchers had a group of non-diabetic men and a group of men with type II diabetes, all more than 60 years of age, exercise on bicycles six times a week for three months. After the three months the doctors measured how much sugar the test subjects’ muscles could make use of as a measure for how well their insulin worked. Associate Professor Dr Flemming Dela of the Muscle Research Center said the tests demonstrated that the exercising diabetics had made as good use of insulin as the healthy non-diabetic persons. “This means that the insulin works just as well for both group. Physical exercise cannot cure people of diabetes, but it can eliminate almost all their symptoms. At the same time it can put off the point at which they have to begin taking insulin,” Dela said. Insulin is a hormone produced by the pancreas(胰腺) , controlling sugar in the body and is used against diabetes. Dela said that to achieve the desired effect diabetics need only exercise to the point where they begin to sweat, but that the activity has to be maintained since it wears off after five days without sufficient exercise. Most diabetics realize that they have to watch their diet while remaining unaware of the importance of exercise, Dela added. 第6题：What is the effect of exercise on elderly people with type II diabetes？ A．It can worsen their symptoms. B．It can help the body make better use of insulin. C．It can help them to eat more. D．It can cure them of the disease.

We rose tint our memories and put ourselves into self-affirming situations. We become defensive when criticized, and apply negative stereotypes to others to boost our own esteem, we stalk around thinking we’re hot stuff. Psychologist and behavioral scientist Nicholas Epley oversaw a key studying into self-enhancement and attractiveness. Rather that have people simply rate their beauty compress with others, he asked them to identify an original photogragh of themselves’ from a lineup including versions that had been altered to appear more and less attractive. Visual recognition, reads the study, is “an automatic psychological process occurring rapidly and intuitively with little or no apparent conscious deliberation”. If the subjects quickly chose a falsely flattering image- which must did- they genuinely believed it was really how they looked. Epley found no significant gender difference in responses. Nor was there any evidence that, those who self-enhance the must (that is, the participants who thought the most positively doctored picture were real) were doing so to make up for profound insecurities. In fact those who thought that the images higher up the attractiveness scale were real directly corresponded with those who showed other makers for having higher self-esteem. “I don’t think the findings that we having have are any evidence of personal delusion”, says Epley. “It’s a reflection simply of people generally thinking well of themselves’. If you are depressed, you won’t be self-enhancing. Knowing the results of Epley ‘s study,it makes sense that why people heat photographs of themselves Viscerally-on one level, they don’t even recognise the person in the picture as themselves, Facebook therefore ,is a self-enhancer’s paradise,where people can share only the most flattering photos, the cream of their wit ,style. ,beauty, intellect and lifestyle. it’s not that people’s profiles are dishonest,says catalina toma of Wiscon—Madison university ,”but they portray an idealized version of themselves. According to the first paragraph, social psychologist have found that ______ . A.our self-ratings are unrealistically high B.illusory superiority is baseless effect C.our need for leadership is unnatural D.self-enhancing strategies are ineffective Visual recognition is believed to be people’s______ .A.rapid watching B.conscious choice C.intuitive response D.automatic self-defence Epley found that people with higher self-esteem tended to______ .A.underestimate their insecurities B.believe in their attractiveness C.cover up their depressions D.oversimplify their illusions The word “Viscerally”(Line 2,para.5) is closest in meaning to_____.A.instinctively B.occasionally C.particularly D.aggressively It can be inferred that Facebook is self-enhancer’s paradise because people can _____.A.present their dishonest profiles B.define their traditional life styles C.share their intellectual pursuits D.withhold their unflattering sides 请帮忙给出每个问题的正确答案和分析，谢谢！

It is unclear what is behind the phenomenon but it may be that beauty creates confidence. The self-confident may appear to be doing better than they are and will not hesitate about asking for a pay rise. Researcher Jason Fletcher, of Yale University in the U.S., rated the attractiveness of the 4,000 men and women. Just over half were judged average, while 7 percent were felt to be very attractive and 8 percent were judged unattractive or very unattractive. The volunteers also sat an IQ test and reported their salary. It became clear that pay scales were far from fair. For instance, a 14- point increase on the IQ score was associated with a 3 to 6 percent increase in wage. But being of above-average looks increased pay by 5 to 10 percent . For a plain person to be paid the same as a very attractive one , they would have to be 40 percent brighter, the journal Economics Letters reports. Dr Fletcher said:“The results do show that people ’s looks have an impact on their wages and it can be very important.” 6.What is the “plainness penalty ”？ A.To be paid less for being ordinarily-looking B.To be laughed at for being ordinarily-looking C.To be fired for being ordinarily-looking D.To be questioned for being ordinarily-looking How many people were rated as very attractive in Jason Fletcher ’s study？A.About 280 B.About 4,000 C.About 2,000 D.About 320 What ’s the average annual salary of a good-looking person？A.￡2,500 B.￡25,000 C.￡22,500 D.￡27,500 Which of the following best summarizes the main idea of the passage ？A.IQ is less important than appearance B.Confidence makes people prettier C.Good looks earn an extra penny D.How Plain Janes get a higher salary Good-looking people are usually paid more probably because________ .A.they look smarter B.they have higher degrees C.they are better at pleasing others D.they are more confident

The differences in relative growth of various areas of scientific research have several causes. (1)Some of these causes are completely reasonable results of social needs.Others are reasonable consequences of particular advances in science being to som
