1、大学英语四级卷二真题 2012 年 12 月及答案解析(总分：710.00，做题时间：120 分钟)一、Directions: For this(总题数：1，分数：142.00)1. （分数：142.00）_二、Reading Comprehensio(总题数：1，分数：71.20)Should Sugar Be Regulated like Alcohol and Tobacco? Sugar poses enough health risks that it should be considered a controlled substance just like alcohol and

2、tobacco, argue a team of researchers from the University of California, San Francisco(UCSF). In an opinion piece called “The Toxic（毒性的）Truth About Sugar“ published Feb. 1 in Nature, Robert Lustig, Laura Schmidt and Claire Brindis argue that its wrong to consider sugar just “empty calories.“They writ

3、e: “There is nothing empty about these calories. A growing body of scientific evidence is showing that fructose（果糖）can trigger processes that lead to liver toxicity and a host of other chronic diseases. A little is not a problem, but a lot kills-slowly.“ Almost everyones heard of-or personally exper

4、ienced-the well-known sugar high, so perhaps the comparison between sugar and alcohol or tobacco shouldnt come as a surprise. But its doubtful that Americans will look favorably upon regulating their favorite vice. Were a nation thats sweet on sugar: the average US adult downs 22 teaspoons of sugar

5、a day, according to the American Heart Association, and surveys have found that teens swallow 34 teaspoons. To counter our consumption, the authors advocate taxing sugary foods and controlling sales to kids under 17. Already, 17% of US children and teens are obese（肥胖的）.and across the world the sugar

6、 intake（摄人）has increased three times in the past 50 years. The increase has helped create a global obesity plague that contributes to 35 million annual deaths worldwide from noninfectious diseases including cancer, heart disease and diabetes. Linda Matzigkeit, a senior vice president at Childrens He

7、althcare, said “We have to do something about this or our country is in danger. Its not good if your state has the second-highest obesity rate. Obese children turn into obese adults.“ “There are good calories and bad calories, just as there are good fats and bad fats. good amino acids（氨基酸） and bad a

8、mino acids,“ Lustig, director of the Weight Assessment for Teen and Child Health program at UCSF, said in a statement. “But sugar is toxic beyond its calories.“ The food industry tries to imply that “a calorie is a calorie.“ says Kelly Brownell, director of the Rudd Center for Food Policy and Obesit

9、y at Yale University. “But this and other research suggests there is something different about sugar,“ says Brownell. The UCSF report emphasizes the metabolic（新陈代谢的）effects of sugar. Excess sugar can alter metabolism, raise blood pressure, affect the signaling of hormones and damage the liver -outco

10、mes that sound suspiciously similar to what can happen after a person drinks too much alcohol. Schmidt. co-chair of UCSFs Community Engagement and Health Policy program. noted on CNN: “When you think about it. this actually makes a lot of sense. Alcohol, after all. is simply made from sugar. Where d

11、oes vodka come from? Sugar.“ But there are also other areas of impact that researchers have investigated: the effect of sugar on the brain and how liquid calories are interpreted differently by the body than solids. Research has suggested that sugar activates the same reward pathways in the brain as

12、 traditional drugs of abuse like morphine or heroin. No one is claiming the effect of sugar is quite that strong, but, says Brownell, “it helps confirm what people tell you sometimes, that they hunger for sugar and have withdrawal symptoms when they stop eating it.“ Theres also something particularl

13、y tricky about sugary drinks. When calories come in liquids, the body doesnt feel as full,“says Brownell. “People are getting more of their calories than ever before from sugared drinks.“ Other countries, including France, Greece and Denmark, impose soda taxes, and the concept is being considered in

14、 at least 20 US cities and states. Last summer, Philadelphia came close to passing a 2-cents-per-ounce soda tax. The Rudd Center has been a strong advocate of a more modest 1-cent-per-ounce tax. But at least one study from 2010, has raised doubts that soda taxes would result in significant weight lo

15、ss: apparently people who are determined to eat-and drink-unhealthily will find ways to do it. Teens 一 no surprise-are good at finding ways to get the things they cant have, so state policies banning all sugar-sweetened drinks from public schools and providing only water, milk or 100% fruit juices h

16、avent had the intended effect of steering kids away from drinking sugared drinks: the average teen consumes about 300 calories per day-thats nearly 15% of his daily calories 一 in sweetened drinks, and the food and drink industry is only too happy to feed this need. Ultimately, regulating sugar will

17、prove particularly tricky because it goes beyond health concerns; sugar, for so many people, is love. A plate of cut-up vegetables just doesnt pack the same emotional punch as a tin of home-made chocolate chip cookies（饼千）,which is why I took my daughter out for a cupcake and not an apple as an after

18、-school treat today. We dont do that regularly-its the first time this school year, actually-and thats what made it special. As a society, could we ever reach the point where wed think apples 一 not a cupcake-are something to get excited over? Says Brindis, one of the reports authors and director of

19、UCSFs Philip R. Lee Institute for Health Policy Studies: “We recognize that there are cultural and celebratory aspects of sugar. Changing these patterns is very complicated.“ For inroads（进展）to be made, say the authors in their statement, people have to be better educated about the hazards of sugar a

20、nd agree that somethings got to change: Many of the interventions（十预）that have reduced alcohol and tobacco consumption can be models for addressing the sugar problem. such as imposing special sales taxes, controlling access, and tightening licensing requirements on vending machines（自动售货机）and snack-b

21、ars that sell high sugar products in schools and workplaces “Were not talking prohibition.“Schmidt said. “Were not advocating a major imposition of the government into peoples lives. Were talking about gentle ways to make sugar consumption slightly less convenient, thereby moving people away from th
