1、大学英语六级分类模拟题 368及答案解析(总分：100.00，做题时间：90 分钟)一、Reading Comprehensio(总题数：0，分数：0.00)You“ve been working out regularly for quite a while, but you“re nowhere near your fitness goals. So now it“s time to bring in your ultimate weaponyour mind. Rather than thinking of fitness as something mysterious that you

2、 do with your body, take an analytical, goal-oriented approach to making physical improvements that stick. Try these tips for creating a smart fitness plan: Define your goals. Whether it“s to lose fat and gain muscle or to run a triathlon, it“s vital to have a goal to work toward. Knowing where you“

3、re going makes it easier to take the fight steps. Get realistic. Training gains are met through consistent effort over a period of time. Don“t expect dramatic, overnight resultsregardless of what exercise equipment infomercials claim. Reward yourself for all the little positive steps you take and fo

4、r consistently striving forward. Be yourself. Work toward a goal that you can achieve with your body. Don“t try to change your basic shape or to go against your own unique physical capabilities. Take an objective look at yourself, and then work toward enhancing what you“ve got rather than trying to

5、attain someone else“s body. Do your research. If you are not making progress, ask a qualified personal trainer to analyze your routine and your goals. Read health and fitness magazines. There“s tons of great fitness information out theretailor it to fit you. Identify your weaknesses, and then use yo

6、ur brain to outsmart them. Many people avoid their weak points or bad habits, hoping that they can ignore them into oblivion. Instead, take them up as clues to how you can improve. Keep a food and fitness journal for a month. Then analyze it for negative patterns. If you always overeat late at night

7、, try going to a late-night movie to get your mind off food. If you tend to fade out on your workouts on weekends, plan some fun exercise with friends to spice up your lagging routine. Create a fitness network. Integrate the important people in your life into your fitness quest. Get your whole group

11、is impossible to build a perfect bodyD.everybody has his / her unique physical capabilities(4).Instead of neglecting your weak points, you should _.（分数：4.00）A.see them as clues for you to improveB.keep a food and fitness journalC.not overeat late at nightD.find out your strengths to be confident(5).

12、Create a fitness network helps you _.（分数：4.00）A.to meet and befriend with important peopleB.to live with people who have the same goalC.to extent your circle of friendsD.to be a leaderHeavier people are more likely to be killed or seriously injured in car accidents than lighter people, according to

13、new research. That could mean car designers will have to build in new safety features to compensate for the extra hazards facing overweight passengers. In the US, car manufacturers have already had to redesign air bags so they inflate to lower pressures, making them less of a danger to smaller women

14、 and children. But no one yet knows what it is that puts overweight passengers at extra risk. A study carried out in Seattle, Washington, looked at more than 26,000 people who had been involved in car crashes, and found that heavier people were at far more risk. People weighing between 100 and 119 k

15、ilograms are almost two-and-a-half times as likely to die in a crash as people weighing less than 60 kilograms. And importantly, the same trend held up when the researchers looked at body mass index (BMI)a measure that takes height as well as weight into account. Someone 1.8metres tall weighing 126

16、kilograms would have a BMI of 39, but so would a person 1.5metres tall weighing 88 kilograms. People are said to be obese if their BMI is 30 or over. The study found that people with a BMI of 35 to 39 were over twice as likely to die in a crash compared with people with a BMI of about 20. It is not

17、just total weight, but obesity itself that“s dangerous. While they do not yet know why this is the case, the evidence is worth pursuing, says Charles Mock, a surgeon and epidemiologist at the Harborview Injury Prevention and Research Centre in Seattle, who led the research team. He thinks one answer

18、 may be for safety authorities to use heavier crash-test dummies when certifying cars as safe to drive. Crash tests normally use dummies that represent standard-sized males weighing about 78 kilograms. Recently, smaller crash-test dummies have also been used to represent children inside crashing car

19、s. But larger and heavier dummies are not used. The reasons for the higher injury and death rates are far from clear. Mock speculates that car interiors might not be suitably designed for heavy people. Besides, obese people, with health problems such as high blood pressure or diabetes, could be foun

20、d it tougher to recover from injury. Richard Kent, an expert in impact biomechanics at the University of Virginia, thinks the new research has established a legitimate connection between obesity and severe injury or death. Because the research used BMI data; it has not confused taller (and therefore

21、 heavier than average) people with those who are overweight. People who are obese might also be at risk because seat belts do not hold them as securely in a crash. “For example, a large amount of fat tissue between the restraint system and the bony thorax acts much like a winter coat: it introduces

22、“slack“ into the restraint system and decreases its performance,“ Kent says.（分数：20.00）(1).The reason why heavy people get injured or killed more easily in traffic accidents _.（分数：4.00）A.lies in drunk drivingB.lies in the air bagC.lies in the safety beltD.is not clearly known yet(2).Which one of the

23、following people is the most likely to get killed in a ear accident?（分数：4.00）A.A man who weighs 60 kilograms.B.A man who weighs 50 kilograms.C.A man whose BMI is 35.D.A man whose BMI is 20.(3).According to the passage, which of the following has no connection with obesity?（分数：4.00）A.Higher rate of d

24、epression.B.Higher death rate in traffic accidents.C.Higher injury rate in traffic accidents.D.Difficulty in recovering from a traffic injury.(4).The word “legitimate“ (Line 2, Para.9) may be replaced by _.（分数：4.00）A.lawfulB.reasonableC.casualD.close(5).What is the main idea of the passage?（分数：4.00）

25、A.Heavy people and light people.B.New safety measures.C.Obesity and risk in driving.D.Obesity and safety belts.Common indoor plants may prove to be a valuable weapon in the fight against rising levels of indoor air pollution. Those plants in your office or home are not only decorative, but NASA scie

26、ntists are finding them to be surprisingly useful in absorbing potentially harmful gases and cleaning the air inside modern buildings. NASA and the Associated Landscape Contractors of America (ALCA) have announced the findings of a 2-year study that suggest the common indoor plant may provide a natu

27、ral way of helping combat “Sick Building Syndrome.“ Research into the use of biological processes as a means of solving environmental problems, both on Earth and in space habitats, has been carried out for many years by Dr. Bill Wolverton, formerly a senior research scientist at NASA“s John C. Stenn

28、is Space Centre, Bay St. Louis, Miss. Based on preliminary evaluations of the use of common indoor plants for indoor air purification and revitalization, ALCA joined NASA to fund a study using about a dozen popular varieties of ornamental plants to determine their effectiveness in removing several k

29、ey pollutants associated with indoor air pollution. NASA research on indoor plants has found that living plants are so efficient at absorbing contaminants in the air that some will be launched into space as part of the biological life support system aboard future orbiting space stations. While more

30、research is needed, Wolverton says the study has shown that common indoor landscaping plants can remove certain pollutants from the indoor environment. “We feel that future results will provide an even stronger argument that common indoor landscaping plants can be a very effective part of a system u

31、sed to provide pollution flee homes and work places“ he concludes. “Plants take substances out of the air through the tiny openings in their leaves,“ Wolverton said. “But research in our laboratories has determined that plant leaves, roots and soil bacteria are all important in removing trace levels

32、 of toxic vapours.“ “Combining nature with technology can increase the effectiveness of plants in removing air pollutants,“ he said. “A living air cleaner is created by combining activated carbon with a potted plant. The roots of the plant grow right in the carbon and slowly degrade the chemicals ab

33、sorbed there,“ Wolverton explains. NASA research has consistently shown that living, green and flowering plants can remove several toxic chemicals from the air in building interiors. You can use plants in your home or office to improve the quality of the air to make it a more pleasant place to live

34、and workwhere people feel better, perform better, and enjoy life more.（分数：20.00）(1).Indoor plants can be used in many ways except _.（分数：4.00）A.showing the owner“s tasteB.decorating offices and homesC.absorbing potentially harmful gasesD.cleaning the air inside buildings(2).The study jointly funded b

35、y ALCA and NASA is based on _.（分数：4.00）A.previous research of common indoor plants“ application in indoor air purification and revitalizationB.laboratory evidence of common indoor plants“ application in indoor air purification and revitalizationC.assumptions of common indoor plants“ use in indoor ai

36、r purification and revitalizationD.tentative evaluations of common indoor plants“ application in indoor air purification and revitalization(3).All the followings are vital to the removal of trace levels of toxic vapours except _.（分数：4.00）A.plant leavesB.plant rootsC.plant stemD.soil bacteria(4).The

37、word “degrade“ (Line 4, Para.7) may be replaced by _.（分数：4.00）A.reduceB.increaseC.neutralizeD.replace(5).People use plants in home or office to make them feel _.（分数：4.00）A.energetic and exaltedB.depressed and lowC.sad and gloomyD.pleasant and comfortableModerate drinking reduces stroke risk, study c

38、onfirms. Similar to the way a drink or two a day protects against heart attacks, moderate alcohol consumptions wards off strokes, a new study found. The study also found that the type of alcohol consumesbeer, wine or liquorwas unimportant. Any of them, or a combination, was protective, researchers r

39、eported in today“s Journal of the American Medical Association . “No study has shown benefit in recommending alcohol consumption to those who do not drink“, cautioned the authors, led by Dr. Ralph L. Sacco of Columbia University College of Physicians and Surgeons in New York. But the new data suppor

40、ts the guidelines of the National Stroke Association, which say moderate drinkers, may protect themselves from strokes by continuing to consume alcohol, the authors said. The protective effect of moderate drinking against heart attack is well established, but the data has been conflicting with alcoh

41、ol and strokes, the author said. The new study helps settle the question and is the first to find blacks and Hispanic benefit as well as whites, according to the authors. Further research is needed among other groups, such as Asian, who past studies suggest may get no stroke protection from alcohol

42、or may even be put at greater risk. Among groups where the protective effect exists, its mechanism appears to differ from the protective effect against heart attacks, which occurs through boosts in level of so-called “good“ cholesterol, the authors said. They speculated alcohol may protect against s

43、troke by acting on some other blood trait, such as the tendency of blood platelets to clump, which is key in forming the blood clots that can cause strokes. The researchers studied 677 New York residents who live in the northern part of Manhattan and had strokes between July 1, 1993, and June 1997.

44、After taking into account differences in other factors that could affect stroke risk, such as high blood pressure, the researchers estimated that subjects who consumed up to two alcoholic drinks daily were only half as likely to have suffered clot-type strokes as non-drinkers. Clot-type strokes acco

45、unt for 80 percent of all strokes, a leading cause of US deaths and disability. Stroke risk increased with heavier drinking. At seven drinks per day, risk was almost triple that of moderate drinkers.（分数：20.00）(1).The principle of protecting oneself from strokes by consuming alcohol reasonably cannot

46、 be applied to _.（分数：4.00）A.heavy drinkersB.light drinkersC.mild drinkersD.non-drinkers(2).Why did researchers find about the relationship between strokes and alcohol consumption before the new study?（分数：4.00）A.They agreed that alcohol consumption could cause strikes.B.They could not find any data t

47、o support the relationship.C.What they found was totally opposite to the new study.D.Their findings were not consistent with another one“s.(3).The new study conducted by Dr. Sacco and his colleagues is unique in that _.（分数：4.00）A.it refutes early studies on the protective effect of moderate drinking

48、 against heart attacksB.it confirms early studies of moderate drinking against heart attacksC.it finds that moderate drinking can benefit people of different races equally wellD.it helps to resolve the disputes over the effect of moderate drinking against strokes(4).How does moderate alcohol consump

49、tion most probably protect us from strokes?（分数：4.00）A.By enhancing the level of the good cholesterol.B.By reducing the possibility of the blood platelets to deposit.C.By reducing the number of blood platelets and blood clots.D.By enhancing the possibility of the blood platelets to deposit.(5).According to the last paragraph, _ are the least likely to suffer clot-type strokes.（分数：4.00）A.people who have two alcoholic drinks dailyB.people who don“t have any alcoholic drinksC.people who have more than two alcoholic drinks dai
