Mark your answers on ANSWER SHEET 1. 40 A study by scientists in Finland has found that mobile phone radiation can cause changes in human cells that might af

23、fect the brain, the leader of the research team said. But Darius Leszczynski, who headed the 2-year study and will present findings next week at a conference in Quebec (魁北克 ), said more research was needed to determine the seriousness of the changes and their impact on the brain or the body. The stu

24、dy at Finlands Radiation and Nuclear Safety Authority found that exposure to radiation from mobile phones can cause increased activity in hundreds of proteins in human cells grown in a laboratory, he said. “We know that there is some biological response. We can detect it with our very sensitive appr

25、oaches, but we do not know whether it can have any physiological effects on the human brain or human body,“ Leszczynski said. Nonetheless the study, the initial findings of which were published last month in the scientific journal Differentiation, raises new questions about whether mobile phone radi

26、ation can weaken the brains protective shield against harmful substances. The study focused on changes in cells that line blood vessels and on whether such changes could weaken the functioning of the blood-brain barrier, which prevents potentially harmful substances from entering the brain from the

27、bloodstream, Leszczynski said. The study found that a protein called hsp27 linked to the functioning of the blood-brain barrier showed increased activity due to irradiation and pointed to a possibility that such activity could make the shield more permeable(能透过的 ), he said. “Increased protein activi

28、ty might cause cells to shrink not the blood vessels but the cells themselves and then tiny gaps could appear between those cells through which some molecules could pass. “ he said. Leszczynski declined to speculate on what kind of health risks that could pose, but said a French study indicated that

29、 headache, fatigue and sleep disorders could result. “These are not life-threatening problems but can cause a lot of discomfort,“ he said, adding that a Swedish group had also suggested a possible link with Alzheimers disease. “Where the truth is I do not know,“ he said. Leszczynski said that he, hi

30、s wife and children use mobile phones, and he said that he did not think his study suggested any need for new restrictions on mobile phone use. 41 According to Leszczynski, how does mobile phone affect ones health? （ A） Mobile phone radiation can increase protein activities and such activities can m

31、ake the protective shield more permeable. （ B） Mobile phone radiation can shrink the blood vessels and prevent blood from flowing smoothly. （ C） Mobile phone radiation will bring stress to people exposed to it. （ D） Mobile phone radiation kills blood cells at a rapid speed. 42 Whats the result of th

32、e French study? （ A） The harm of mobile phone radiation is life-threatening. （ B） Mobile phone may affect ones normal way of thinking. （ C） Sleep disorders could result from mobile phone radiation. （ D） A protein called hsp27 is killed by mobile phone radiation. 43 What kind of disease is not caused

33、 by the use of mobile phone? （ A） Fatigue. （ B） Headache. （ C） Alzheimers disease. （ D） Tuberculosis. 44 According to the passage, what would be the future of the use of mobile phone? （ A） People will be forbidden to use mobile phone. （ B） People dare not use mobile phone because of its radiation. （

34、 C） People will continue to use mobile phone. （ D） There will be new restrictions on the use of mobile phone. 45 Which of the following is NOT true according to the passage? （ A） The research in Finland found that mobile phone radiation will affect ones brain. （ B） Mobile phone radiation can cause i

35、ncreased activity in hundreds of protein in human cells. （ C） Increased protein activity might cause cells to shrink. （ D） Lszczynski forbade his wife and children to use mobile phone after his research. 45 Specialisation can be seen as a response to the problem of an increasing accumulation of scie

36、ntific knowledge. By splitting up the subject matter into smaller units, one man could continue to handle the information and use it as the basis for further research. But specialisation was only one of a series of related developments in science affecting the process of communication. Another was t

37、he growing professionalisation of scientific activity. 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 scient

38、ific community and, in particular, may not fully share its values. The growth of specialisation in 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 area

39、s 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 re

40、search, 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 onl

41、y if they incorporate, and reflect on, the wider geological 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

42、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 reader

43、ship. 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 profes

44、sionalisation 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 struc

45、ture of science. 46 The growth of specialisation in the 19th century might be more clearly seen in sciences such as_. （ A） society and chemistry （ B） physics and psychology （ C） sociology and psychology （ D） physics and chemistry 47 We can infer from the passage that_. （ A） there is little distincti

46、on between specialisation and professionalisation （ B） amateurs can compete with professionals in some areas of science （ C） professionals tend to welcome amateurs into the scientific community （ D） amateurs have national academic societies but no local ones 48 The author writes of the development o

47、f geology to demonstrate_. （ A） the process of specialisation and professionalisation （ B） the hardship of amateurs in scientific study （ C） the change of policies in scientific publications （ D） the discrimination of professionals against amateurs 49 The direct reason for specialisation is_. （ A） t

48、he development in communication （ B） the growth of professionalisation （ C） the expansion of scientific knowledge （ D） the splitting of academic societies 49 A multinational corporation is a corporate enterprise, which though headquartered in one country, conducts its operations through branches tha

49、t it owns or controls around the world. The organizations, mostly based in the United States, Western Europe, and Japan, have become major actors on the international stage, for some of them are wealthier than many of the countries they operate in. The less developed countries often welcome the multinationals because they are a source of investment and jobs. Yet their presence has its drawbacks, for these organizations soon develop immense political and ec
