If this happens early enough, the disease can often be treated succe

19、ssfully. 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 because the radiation brings a small ri

20、sk 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 estimating the womens cumulative dose of r

21、adiation, 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 women, 18 of them fatal. The model preferr

22、ed by the LIN 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 discovered and treated. The Valencia programme

23、, 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, because they would be exposed to less rad

24、iation. 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 the study should be interpreted with cauti

25、on. “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 minimised in any screening programme.“（分数：8.00）(1).Paragraph 2 _ A Harm Screening May Do to a Younger Woman B Investiga

29、uld have died of childhood diseases if they had been born 100 years ago. Because more people live longer, there are more people around at any given time.

41、 the underwater world has been explored. Now, Scientists at the Woods Hole Oceanographic Institution (WHOI) in Massachusetts are building an underwater vehicle that will carry explorers as deep as 6,500 meters (21,320 feet). The new machine, known as a manned submersible or human-operated vehicle (H

42、OV), will replace another one named Alvin which has an amazing record of discovery, playing a key role in various important and famous undersea expeditions. Alvin has been operating for 40 years but can go down only 4,500 meters (14,784 feet). Its about time for an upgrade, WHOI researchers say.Alvi

43、n was launched in 1964. Since then, Alvin has worked between 200 and 250 days a year, says Daniel Fornari, a marine geologist and director of the Deep Ocean Exploration Institute at WHOI. During its lifetime, Alvin has carried some 12,000 people on a total of more than 3,000 dives. A newer, better v

44、ersions of Alvin is bound to reveal even more surprises about a world that is still full of mysteries, Fornari says. It might also make the job of exploration a little easier. “We take so much for granted on land,“ Fomari says. “We can walk around and see with our eyes how big things are. We can see

45、 colors, special arrangements.“Size-wise, the new HOV will be similar to Alvin. Itll be about 37 feet long. The setting area inside will be a small sphere, about 8 feet wide, like Alvin, itll carry a pilot and two passengers. It will be just as maneuverable. In most other ways, it will give passenge

Alvin has only three windows, the new vehicle will have five, with more overlap so that the passengers and the pilot can see the same thing.Alvin can go up and down at a rate of 30 meters every second, and its maximum speed is 2 knots ( about 2

47、.3 miles per hour), while the new vehicle will be able to ascend and descend at 44 meters per second.
