7、he fine art of learning in their sleep.By the time babies are a year old. They can recognize a lot of sounds and even simple words. Marie Cheour at the University of Turku in Finland suspected that they might progress this fast because they learn language while they sleep as well as when they are aw

8、ake.To test the theory, Cheour and their colleagues studied 45 newborn babies in the first days of their lives. They exposed all the infants to an hour of Finnish vowel sounds one that sounds like “oo“, another like “ee“ and a third boundary vowel peculiar to Finnish and similar languages that sound

9、s like something in between. EEG (脑电图) recording of the infants brains before and after the session showed that the newborns could not distinguish the sounds.Fifteen of the babies then went back with their mothers, while the rest were split into two sleep-study groups.

They could identify the sound even when its pitch was changed, while none of the other babies could pick up the boundary vowel at all.Cheour doesnt know how babies accomplish this nighttime learning, but she suspects that the special ability might indicate that unlike adu

So forget the idea that you can pick up the tricky French vowels as an adult just by slipping a language tape under your pillow. But while it may not

Every year millions of women are screened with X-rays to pick up signs of breast cancer. If this happens early enough, t

17、he disease can often be. treated successfully. According to a survey published last year, 21 countries have screening programmes. Nine of them, including Australia, Canada, the US and Spain, screen women under 50.2. But the medical benefits of screening these younger women are controversial, partly

18、because the radiation brings a small risk of inducing cancer. Also, younger women must be given higher doses of X-rays because their breast tissue is denser.3. Researchers at the Polytechnic University of Valencia analysed the effect of screening more than 160,000 women at 11 local clinics. After es

19、timating the womens cumulative dose of radiation, they used two models to calculate the number of extra cancers this would cause.4. The mathematical model recommended by Britains National Radiological Protection Board (NRPB) predicted that the screening programme would cause 36 cancers per 100,000 w

20、omen, 18 of them fatal. The model preferred by the UN Scientific Committee on the Effects of Atomic Radiation led to a lower figure of 20 cancers.5. The researchers argue that the level of radiation-induced cancers is “not very significant“ compared to the far larger number of cancers that are disco

21、vered and treated. The Valencia programme, they say, detects between 300 and 450 cases of breast cancer in every 100,000 women screened.6. But they point out that the risk of women contracting cancer from radiation could be reduced by between 40 and 80 percent if screening began at 50 instead of 45,

22、 because they would be exposed to less radiation. The results of their study, they suggest, could help “optimise the technique“ for breast cancer screening.7. “There is a trade-off between the diagnostic benefits of breast screening and its risks,“ admits Michael Clark of the NRPB. But he warns that

23、 the study should be interpreted with caution. “On the basis of the current data, for every 10 cancers successfully detected and prevented there is a risk of causing one later in life. Thats why radiation exposure should be minimized in any screening programme.“（分数：8.00）(1).Paragraph 2_（分数：1.00）A.Ri

Continental densities range from no permanen

27、t inhabitants in Antarctica to 211 per square mile in Europe. In the western hemisphere, population densities range from about 4 per square mile in Canada to 675 per square mile in Puerto Rico. In Europe the range is from 4 per square mile in Iceland to 831 per square mile in the Netherlands.Within

28、countries there are wide variations of population densities. For example, in Egypt, the average is 55 persons per square mile, but 1,300 person inhabit each square mile in settled portions where the land is arable (适合耕种的).High population densities generally occur in regions of developed industrializ

29、ation, such as the Netherlands, Belgium, and Great Britain, or where lands are intensively used for agriculture, as in Puerto Rico and Java. Low average population densities are characteristic of most Underdeveloped countries.Low density of population is generally associated with a relatively low pe

30、rcentage of cultivated land. This generally results from poor quality lands. It may also be due to natural obstacles to cultivation, such as deserts, mountains, or malaria-infested (疟疾横行) jungles; to land uses other than cultivation, as pasture and forested land; to primitive methods that limit cult

31、ivation; to social obstaclesMore economically advanced countries of low population density have, as a rule, large proportions of their populations living :in urban areas. Their rural population densities are usually very low. Poorly developed countries of correspondingly low population density, on t

32、he other hand, often have a concentration of rural population living on arable land, which is as great as the rural concentration found in the most densely populated industrial countries.（分数：15.00）(1).Which of the following area has the highest average population density?（分数：3.00）A.Iceland.B.Canada.

Now evidence gleaned from mud deposited by the R

36、iver Nile suggests that a shift in climate thousands of kilometers to the south was ultimately to blem and the same or worse could happen today.The ancient Egyptians depended on the Niles annual floods to irrigate their crops. But any change in climate that pushed the African monsoons southwards out

37、 of Ethiopia would have diminished these floods.Dwindling rains in the Ethiopian highlands would have meant fewer plants to stablise the soil. When rain did fall it would have washed large amounts of soil into the Blue Nile and into Egypt, along with sediment from the White Nile.The Blue Nile mud ha

38、s a different isotope signature from that of the White Nile. So by analyzing isotope differences in mud deposited in the Nile Delta, Michael Krom of Leeds University worked out what proportion of sediment came from each branch of the river.Krom reasons that during periods of drought, the amount of t

39、he Blue Nile mud in the river would be relatively high. He found that one of these periods, from 4,500 to 4,200 years ago, immediately predates the fall of the Egypts Old Kingdom.The weakened waters would have been Catastrophic for the Egyptians. “Changes that affect food supply dont have to be very

45、s will offer up their bodies to the sun rays. A tan indicates health and beauty, and most sun worshippers will sacrifice a lot to achieve it, including themselves.With each hour, the suns ultraviolet (紫外线的) radiation produces irreversible (不可逆的) damage, hastening the development of unsightly wrinkle

46、s. And with each year on the beach or rooftop, the sunbather increases his risk of getting skin cancer. Skin cancer is by far the most common form of cancer. An estimated 400,000 new cases will be detected this year in the United States, and almost all of them can be blamed on over-exposure to the s

47、un.Fortunately ,most of these cancers are highly curable. But they can be disfiguring and take time to treat. For that reason, sun worshippers should treat deity with a good deal of awe(敬畏). Sunburn, of course, is the initial hazard posed by UV radiation. Prolonged exposure to UV, however, interfere

48、s with the production of collagen fibers in the dermis (真皮层), causing the skin to lose elasticity (弹性) and creating premature wrinkles. Further deterioration (恶化) of the dermis deprives the epidermis (表皮层)of nutrition and causes it to become thin and dry.Cancer is UVs final result. Shortwave radiant

49、 energy, especially from the UV-B band, breaks the strands of DNA. Enzymes (酶) work constantly to rearrange the (变异的) DNA into proper sequence, but with repeated UV exposure, the repair process may eventually break down. Then the mutant DNA may produce a colony of cancer cells. But skin cancer may be avoided with a good dose of common sense. People with fair skin and blue eyes who burn easily stand the highest risk. Special danger spots
