7、D.二、B第 2部分：阅读判断/B(总题数：1，分数：7.00)Trees1. Trees are plants that survive year after year and have a single main stem composed entirely of wood. Some kinds grow to only ten feet. Others attain heights of more than 350 feet. These giants also have stems that are as much as 100 feet in circumference (圆周).

8、2. Over 25,000 different species of tree grow around the wood, except near the North and South Poles. They all belong to one of two possible groups. They are either coniferous (松类的) or deciduous (落叶的). Coniferous trees are evergreens (常绿的), such as pine or fir, which bear needlelike foliage (叶子) all

9、 year long. Many deciduous trees have broad leaves, which they usually shed each year at the beginning of the cold season.3. Trees provide people with a host of oils, drugs, glues, candy, cloths, fuels, and well over 10,000 wooden products. Some have unique qualities that make their wood valuable fo

10、r special purposes. One particular type of tree, for example, is used to make fishing rods because it is not strong but unusually flexible. Queensland walnut is used by the electrical industry in Australia, because it is almost as good an electrical insulator as rubber. One of the world most unusual

11、 trees is the teak (柚木). It is one of the heaviest of all woods, and it has the largest leaves of any tree. These enormous leaves are two feet square and their surface is so tough and coarse that cabinetmakers in India use them as sandpaper. Teakwood itself is so heavy that when a teak tree is first

12、 cut down it will not float in water. It takes three years for the ten or fifteen-ton trunk to dry out enough so it will not sink.4. Of all the worlds billions of living trees, the tallest is a giant redwood in California. It towers 368 feet. This redwood tree is anchored and nourished by a massive

13、root system. It extends over three full acres.（分数：7.00）(1).Trees grow every corner of the world.

Every year millions of women are screened with X-rays to pick up signs of breast cancer. If this happens early enough, the disease can often be treated

16、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 benefit of screening these younger women are controversial, partly because the radiation brings a sma

17、ll 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 estimating the womens cumulative dos

18、e 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 women, 18 of them fatal. The model

19、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 discovered and treated. The Valencia pr

20、ogramme, 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

21、less radiation. The results of their study, they suggest, could help “optimize 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 w

22、ith 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 minimised in any screening programme.“AHarm Screening May Do to a Younger WomanBInvestigating the Effect of Sc

Yet occurrences of shortages and droughts (干旱) are causing famine and distress in some areas, and in

26、dustrial and agricultural by-products are polluting water supplies. Since the worlds population is expected to double in the next 50 years, many experts think we are on the edge of a widespread water crisis.But that doesnt have to be the outcome. Water shortages do not have to trouble the worldif we

27、 start valuing water more than we have in the past. Just as we began to appreciate petroleum more after the 1970s oil crises, today we must start looking at water from a fresh economic perspective. We can no longer afford to consider water a virtually free resource of which we can use as much as we

28、like in any way we want.Instead, for all uses except the domestic demand of the poor, governments should price water to reflect its actual value. This means charging a fee for the water itself as well as for the supply costs.Governments should also protect this resource by providing water in more ec

29、onomically and environmentally sound ways. For example, often the cheapest way to provide irrigation (灌溉) water in the dry tropics is through small-scale projects, such as gathering rainfall in depressions (凹地) and pumping it to nearby cropland.No matter what steps governments take to provide water

30、more efficiently, they must change their institutional and legal approaches to water use. Rather than spread control among hundreds or even thousands of local and regional agencies that watch various aspects of water use, countries should set up central authorities to coordinate water policy.（分数：15.

A.build big

34、 lakes to store water B.construct big pumping stations C.build small and cheap irrigation systems D.channel water from nearby rivers to cropland（分数：3.00）A.B.C.D.(5).In order to raise the efficiency of the water supply, measures should be taken to _. A.guarantee full protection of the environment B.c

36、rance than menmuch less likely to admire what they see in the mirror. Up to 8 out of 10 women are dissatisfied with their reflection, and more than half may see a distorted image.Men looking in the mirror are more likely to be either pleased with what they see or indifferent. Research shows that men

37、 generally have a much more positive body image than womenif anything, they may tend to over-estimate their attractiveness. Some men looking in the mirror may literally not see the flaws in their appearance.Why are women so much more self-critical than men? Because women are judged on their appearan

38、ce more than men, and standards of female beauty are considerably higher and more inflexible. Women are continually bombarded with images of the “ideal“ face. And constant exposure to idealized images of female beauty on TV, magazines and billboards makes exceptional good looks seem normal and anyth

39、ing short of perfection seem abnormal and ugly. It has been estimated that young women now see more images of outstandingly beautiful women in one day than our mothers saw throughout their entire adolescence.Also, most women trying to achieve the impossible standards of female beauty have in fact be

40、come progressively more unrealistic during the last century. In 1917, the physically perfect woman was about 5 feet 4 inches tall and weighed nearly 10 stone (英石). Even 25 years ago, top models and beauty queens weighed only 8% less than the average women, now they weigh 23% less. The current media

41、ideal for women is achievable by less than 5% of the female populationand thats just in terms of weight and size. If you want the ideal shape, face etc., its probably more like 1%.（分数：15.00）(1).The main purpose of the passage is to _. A.explain a phenomenon B.compare two facts C.make a suggestion D.

A.denied B.doubtful of C.very proud of D.influenced by（分数：3.00）A.B.C.D.(4).Which of the following can be inferred about the physically perfect

44、 woman in 1917? A.She was not very much different from the average women. B.She was hardly achievable by the female population. C.She looked into the mirror more often than women today. D.She was regarded perfect only in terms of her face.（分数：3.00）A.B.C.D.(5).Today perfect woman is achievable, in te

46、s, using the same evolutionary principles.Krister Wolff and Peter Nordin of Chalmers University of Technology (CUT) in Gothenburg, Sweden, built a winged robot and set about testing whether it could learn to fly by itself, without any pre-programmed data on what flapping is or how to do it.To begin

47、with, the robot just twitched and jerked erratically. But, gradually, it made movements that gained height. At first, it cheatedsimply standing on its wing tips was one early short cut. After three hours, however, the robot abandoned such methods in favor of a more effective flapping technique where it rotated its wings through 90 degrees and raised them before twisting them back to the horizontal and pushing down.“This tells us that this kind of evolution is capable of coming up with flying motion,“ says Peter Bentley, who works on evolutio
