Brazil has become one of the developing world’s great successes in reducing population growth — but more by accident than by design. While countries such as India are making great efforts to reduce the birth rate,学习 Brazil has had better result without really trying, says George Martine at Harvard. Brazil’s population growth rate dropped from 2.99% a year between 1951 and 1960 to 1.63% a year between 2000 and 2010, and now Brazilian women have only 2.7 children on average. Martine says this figure will continue to fall in the coming decades, an achievement that makes Brazil the envy of many other Third World countries. Martine puts it down to, among other things, soap operas and installment (分期付款) plans introduced in the 1970s. Both have played an important, although indirect, role in lowering the birth rate. Brazil is one of the world’s biggest producers of soap operas. Global, the nation’s most popular television network, broadcasts soap operas for at least three hours every night. “Most soap operas are based on stories happening in wealthy families. They describe the values of the middle and upper classes — not many children, different attitudes towards sex, women working,” says Martine. “They have sent the images to all parts of Brazil and managed to make people conscious of the values and the patterns of behavior.” Meanwhile, the installment plans may encourage the poor to become consumers. “This has led to an enormous change in consumption patterns and consumption seems incompatible with unlimited reproduction,” says Martine. 41. According to the passage, Brazil has cut back its population growth ____________. A. by educating its citizens B. by careful family planning C. by making great efforts D. by chance 42. According to the passage, many Third World countries ____________. A. are unconscious of the importance of birth control B. will soon join Brazil in successfully reducing their birth rate C. haven’t found effective measures to control their population growth D. have a good understanding of the role soap operas play in family planning 43. The phrase “puts it down to” (Line 1, Para. 3) is close in meaning to ____________. A. attributes it to B. finds it a reason for C. sums it up as D. compares it to 44. Soap operas have helped Brazil lower its birth rate because ____________. A. they can keep people sitting long hours watching TV B. they have gradually changed people’s views of life C. they have turned most Brazilians into members of the middle and upper classes D. they can popularize birth control measures 45. What is Martine’s conclusion about Brazil’s population growth? A. The increase in the birth rate will promote consumption. B. The desire for consumption helps reduce the birth rate. C. Consumption can be compatible with unlimited reproduction. D. A country’s economy has nothing to do with its population growth

3、Part Ⅲ Reading Comprehension (20’) Section A (2’×5=10’) Directions: There is 1 passage in this section. The passage is followed by some questions. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and write the corresponding letter on Answer Sheet. Questions 21 to 25 are based on the following passage. The health-care economy is filled with unusual and even unique economic relationships. one of the least understood involves the peculiar roles of producer or "provider" and purchaser or "consumer" in the typical doctor-patient relationship. in most sectors of the economy, it is the seller who attempts to attract a potential buyer with various inducements of price, quality, and utility, and it is the buyer who makes the decision. Such condition, however, does not prevail in most of the health-care industry. In the health-care industry, the doctor-patient relationship is the mirror image of the ordinary relationship between producer and consumer. Once an individual has chosen to see a physician- and even then there may be no real choice - it is the physician who usually makes all significant purchasing decisions: whether the patient should return next Wednesday", whether X-rays are needed , whether drugs should be prescribed etc. It is a rare and sophisticated patient who will challenge such professional decisions or raise in advance questions about price, especially when the disease is regarded as serious. This is particularly significant in relation to hospital care. The physician must certify the need for hospitalization, determine what procedures will be performed, and announce when the patient may be discharged. The patient may be consulted about some of these decisions, but in the main it is the doctor's judgments that are final. Little wonder then that in the eye of the hospital it is the physician who is the real "consumer." As a consequence, the medical staff represents the "power center" in hospital policy and decision-making, not the administration. Although usually there are in this situation four identifiable participants - the physician, the hospital, the patient, and the payer (generally an insurance carrier or government) - the physician makes the essential decision for all of them. The hospital becomes an extension of the physician; the payer generally meets most of the bills generated by the physician/hospital, and for the most part the patient plays a passive role. We estimate that about 75-80 percent of health-care expenditures are determined by physicians, not patients. For this reason, the economy directed at patients or the general is relatively ineffective. 21. What's the author's main purpose in writing this passage? A. To criticize doctors for exercising too much control over patients. B. To analyze some important economic factors in health-care. C. To urge hospitals to reclaim their decision-making authority. D. To inform potential patients of their health-care rights. 22. In the health-care industry, the patients _____. A. perform the role of being "providers" B. decide which physician to consult C. never raise questions about price D. never consult with the doctors 23. According to the author, when a doctor tells a patient to "return next Wednesday", the doctor is in effect _____. A. instructing the patient to buy more medical services B. warning the patient that a hospital stay might be necessary C. advising the patient to seek a second opinion D. admitting that the initial visit was ineffective 24. Doctors are able to determine hospital policies most probably because _____. A. it is doctors who generate income for the hospital B. a doctor is ultimately responsible for a patient's health C. most of the patients don't challenge the doctor's decisions D. the administration doesn't know about medicine as much as doctors 25. The author is most probably leading up to _____ A. an analysis of the role of the hospital administration B. a study of lawsuit against doctors' malpractice C. a discussion of a new medical treatment D. a proposal to control medical costs Section B (2’×5=10’) Directions: There is 1 passage in this section. The passage is followed by some questions. You should write down your answers to each question on Answer Sheet. Questions 26 to 30 are based on the following passage. The Trouble with Biofuels Maybe it was simply too good to be true. For proponents, biofuels — petroleum substitutes made from plant matter like corn or sugar cane — seemed to promise everything. Using biofuels rather than oil would reduce the greenhouse gases that accelerate global warming, because plants absorb carbon dioxide when they grow, balancing out the carbon released when burned in cars or trucks. Using homegrown biofuels would help the U.S. reduce its utter dependence on foreign oil, and provide needed income for rural farmers around the world. And unlike cars powered purely by electric batteries or hydrogen fuel cells — two alternate technologies that have yet to pan out — biofuels could be used right now. But according to a pair of studies published in the journal Science recently, biofuels may not fulfill that promise — and in fact, may be worse for the climate than the fossil fuels they're meant to supplement. According to researchers at Princeton University and the Nature Conservancy, almost all the biofuels used today cause more greenhouse gas emissions than conventional fuels, if the full environmental cost of producing them is factored in. As virgin land is converted for growing biofuels, carbon dioxide is released into the atmosphere; at the same time, biofuel crops themselves are much less effective at absorbing carbon than the natural forests or grasslands they may be replacing. "When land is converted from natural ecosystems it releases carbon," says Joseph Fargione, a lead author of one of the papers and a scientist at the Nature Conservancy. "Any climate change policy that doesn't take this fact into account doesn't work." Many environmentalists have been making the case against biofuels for some time, arguing that biofuel production takes valuable agricultural land away from food, driving up the price of staple crops like corn. But the Science papers make a more sweeping argument. In their paper, Fargione's team calculated the "carbon debt" created by raising biofuel crops — the amount of carbon released in the process of converting natural landscapes into cropland. They found that corn ethanol produced in the U.S. had a carbon debt of 93 years, meaning it would take nearly a century for ethanol, which does produce fewer greenhouse gases when burned than fossil fuels, to make up for the carbon released in that initial landscape conversion. Palm tree biodiesel in Indonesia and Malaysia — one of the most controversial biofuels currently in use, because of its connection to tropical deforestation in those countries — has a carbon debt of 86 years. Soybean biodiesel in the Amazonian rainforest has a debt of 320 years. "People don't realize there is three times as much carbon in plants and soil than there is in the air," says Fargione. "Cut down forests, burn them, churn the soil, and you release all the carbon that's been stored." Worse, as demand for biofuels go up — the European Union alone targets 5.75% of all its transport fuel to come from biofuel by the end of the year — the price of crops rises. That in turn encourages farmers to clear virgin land and plant more crops, releasing even more carbon in a vicious cycle. For instance, as the U.S. uses more biodiesel, much of which is made from soybeans or palm oil, farmers in Brazil or Indonesia will clear more land to raise soybeans to replace those used for fuel. "When we ask the world's farmers to feed 6 billion people and ask them to produce fuel, that requires them to use additional land," says Fargione. "That land has to come from somewhere." Industry groups like the Renewable Fuels Association criticized the studies for being too simplistic, and failing to put biofuels in context. And it's true that the switch to biofuels can have benefits that go beyond climate change. Biofuels tend to produce less local pollution than fossil fuels, one reason why Brazil — which gets 30% of its automobile fuel from sugar-cane ethanol — has managed to reduce once stifling air pollution. In the U.S., switching to domestically produced biofuels helps cut dependence on foreign oil, and boosts income for farmers. But in all of these cases, the benefits now seem to pale next to the climate change deficits. Fargione points out that if the U.S. managed to use 15 billion gallons of ethanol by 2015 — as is mandated in last year's energy bill — it would still only offset 7% of projected energy demand. That won't put Venezuela or Iran out of business. This is all depressing news, especially if you're a corn farmer. Biofuels are one of the few alternative fuels that are actually available right now, but the evidence suggests we be better off not relying on them. But even Fargione doesn't argue that we should ditch biofuels altogether. Biofuels using waste matter — like wood chips, or the leftover sections of corn stalks — or from perennial plants like switchgrass, effectively amount to free fuel, because they don't require clearing additional land. "There's no carbon debt," notes Fargione. Unfortunately, the technology for yielding fuel from those sources — like cellulosic biofuels — is still in its infancy, though it is improving fast. In the end, the right kind of biofuel won't be a silver bullet, but just one more tool in the growing arsenal against climate change. 26.

6、Part Ⅴ Writing (20’) Section B (10’×1=10’) Directions: Summarize the main ideas of the following source material by using different wording and structures from the original. Source material Objects that are vibrating make sounds. Rhythmic sound vibrations produce sound waves which travel in every direction. The frequency of a sound is the number of waves that pass a given point each second. The more rapidly an object vibrates, the greater the frequency of sound it makes. Frequency is measured in hertz. One hertz equals one sound wave per second. The frequency of sound determines the degree of highness or lowness of the sound. A high-pitched sound has a higher frequency than a low-pitched sound. Humans hear sounds that have frequencies from about 20 hertz to 20,000 hertz. Sound with a frequency higher than 20,000 hertz is called ultrasound which is too high-pitched for humans to hear. However, many animal can hear ultrasound. Bats can hear higher sounds than any other animal. Some can hear up to 210,000 hertz. Bats sent out lots of high-pitched squeaks and then listen to the echoes bouncing off things like insects. The shorter the time interval between the squeak and the echo, the closer they to the insect. Using sound to find or "see" things is called echolocation. Another animal that uses ultrasound is the dolphin. Dolphins can hear sounds up to about 150,000 hertz. Dolphins use sound waves to find food underwater. They make clicking sounds that hit whatever is around them and then bounce back to the dolphins. Dolphins can send as many as 2,000 clicks per second. Dolphins' ultrasound ability is so sensitive that they can detect small fish from 10 feet away. 45.____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
