16、子。BAlaska/B1. In 1868 Americans welcomed Alaska into the Union as the 49th state, symbolizing a change of attitude from that held in 1867, when the peninsula was purchased from Russia. Then, most Americans had little interest in 1,500,000 square kilometers “of icebergs and polar bears” beyond Canada
17、s western borders, far from the settled areas of the United States.2. In those sections of the state which lie above the Arctic Circle, Alaska still is a land of icebergs and polar bears. Ice masses lie buried in the earth, which is permanently frozen to a depth of 90 or more meters. From early May
18、until early August, the midnight sun never sets on this flat, treeless region, but the sun cannot melt the icy soil more than two-thirds of a meter down.3.

27、 clusters of cases around industrial sites are the result of population mixing that increases 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.“
28、Childhood leukaemia appears to be an unusual result of a common infection,” said Sir Richard 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 peop
29、le from large towns in a rural area, where you might have people who had not been exposed to 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 no
30、rthern England. Scientists have been trying to establish why there was more leukaemia in children 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 ha
31、ve been predicted because of the amount of population mixing going on in the area, as large numbers 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 pa
32、rents are incomers or locals, are at a higher risk if they are born in an area of high population 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,
33、 a cancer epidemiologist at Oxford University, who said that exposure to a common unidentified infection through population mixing resulted in the disease.（分数：15.00）(1).Who first hinted at the possible cause of childhood leukaemia by infection?_（分数：3.00）A.Leo Kinlen.B.Richard Doll.C.Louise Parker.D.
34、Heather Dickinson.(2).Which statement can be supported by Heather Dickinson and Louise Parkers new findings? _（分数：3.00）A.Radiation has contributed to the disease.B.Putting a lot of people from rural area in a large towns increases the risk of childhood leukaemia.C.Population mixing is the most impor

36、a.C.Radiation has nothing to do with childhood leukaemia.D.Children born in a large town are at higher risk of leukaemia.(4).Cancer Research Campaign is most possibly a_.（分数：3.00）A.medical journalB.research instituteC.private companyD.governmental agency(5).This passage is mainly about_.（分数：3.00）A.t

38、adiation 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 change
39、s 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 respo
40、nse. 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 Differentiation, rai
41、ses 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 potentially harm
42、ful 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 more perme
43、able(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 could pos
44、e, 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 not know,”
45、he said.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.（分数：15.00）(1).According to Leszczynski, how does mobile phone affect ones health? _（分数：3.00）A.Mobile phone radiation can
46、increase protein activities and such activities can make 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
