10、exposure. The research published in the British Journal of Cancer backs up a 1988 theory that some as yet unidentified infection caused leukaemianot the environmental factors widely blamed for the disease. “Childhood leukaemia appears to be an unusual result of a common infection,” said Sir Richard
11、Doll, an internationallyknown cancer expert who first linked tobacco with lung cancer in 1950. “A virus is the most likely explanation. You would get an increased risk of it if you suddenly put a lot of people from large towns in a rural area, where you might have people who had not been exposed to
12、the infection.” Doll was commenting on the new findings by researchers at Newcastle University, which focused on a cluster of leukaemia cases around the Sellafield nuclear reprocessing plant in Cumbria in northern England. Scientists have been trying to establish why there was more leukaemia in chil
13、dren around the Sellafield area, but have failed to establish a link with radiation or pollution. The Newcastle University research by Heather Dickinson and Louise Parker showed the cluster of cases could have been predicted because of the amount of population mixing going on in the area, as large n
14、umbers of construction workers and nuclear staff moved into a rural setting. “Our study shows that population mixing can account for the (Sellafield) leukaemia cluster and that all children, whether their parents are incomers or locals, are at a higher risk if they are born in an area of high popula
15、tion mixing,” Dickinson said in a statement issued by the Cancer Research Campaign, which publishes the British Journal of Cancer. Their paper adds crucial weight to the 1988 theory put forward by Leo Kinlen, a cancer epidemiologist at Oxford University, who said that exposure to a common unidentifi

17、 radiation can cause changes in human cells that might affect 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 cha
18、nges and their impact on the brain or the body. The study 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
19、response. We can detect it with our very sensitive approaches, 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 Differentiatio
20、n, raises new questions about whether mobile phone radiation 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 potential
21、ly harmful substances from entering the brain from the 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 mo
22、re permeable(能透过的), he said. “Increased protein activity might cause cells to shrinknot the blood vessels but the cells themselvesand 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
23、 could pose, but said a French study indicated that 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 do

Leszczynski said that he, his 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.According to Leszczynski, how does mobile phone affect ones health _ AMobile phone radiation can increase pr

26、. 47.B第三篇/BBProblems of Internet/B The proportion of works cut for the cinema in Britain dropped from 40 per cent when I joined the BBFC in 1975 to less than 4 per cent when I left. But I dont think that 20 years from now it will be possible to regulate any medium as closely as I regulated film. The
27、 Internet is, of course, the greatest problem for this century. The world will have to find a means, through some sort of international treaty of United Nations initiative, to control the material thats now going totally unregulated into peoples homes. That said, it will only take one little country

29、me as enjoy the technical manoeuvres (策略)that enable you to win. But in respect of violence in mainstream films, Im more optimistic. Quite suddenly, tastes have changed, and its no longer Stallone or Schwarzenegger who are the top stars, but Leonardo DiCapriothat has taken everybody by surprise. Go
30、through the most successful films in Europe and America now and you will find virtually none that we are violent. Quentin Tarantino didnt usher in a new, violent generation, and films are becoming much more prosocial than one would have expected. Cinemagoing will undoubtedly survive. The new multipl
31、exes are a glorious experience, offering perfect Sound and picture and very comfortable seats, thins which had died out in the 1980s. I cant believe weve achieved that only to throw it away in favor of huddling around a 14-inch computer monitor to watch digitally delivered movies at home. It will be
32、come increasingly cheap to make films, with cameras becoming smaller and lighter but remaining very precise. That means greater chances for new talent to emerge, as it will be much easier for people to learn how to be better film-makers. Peoples working lives will be shorter in the future, and once
33、retired they will spend a lot of time learning to do things that amuse themlike making videos. Fifty years on we could well be media-saturated as producers as well as audience; instead of writing letters, one will send little home movies entitled My Week.Which of the following about Internet is true
34、 according to the passage _ AThe Internet is the greatest progress for this century.BEfforts are needed to control Internet.CParaguay refused to sign a treaty for transmission.DThe United Nations has found ways to prevent Internet from developing. 48.阅读下面的短文，文中有15处空白，每处空白给出了4个选项，请根据短文的内容从4个选项中选择1个最佳
