问题     The average American drinks a gallon of soda a week, which delivers roughly 1, 000 calories and no nutrition. The average American is also overweight or obese. Could changing one of those things help change the other?
    A growing number of officials think so, which accounts for a spate of proposed new taxes on soda as a way to discourage consumption while at the same time raising money to fund other obesity-fighting initiatives. Some 20 states and cities, from New Mexico to Baltimore, contemplated soda taxes this spring.
    The reaction against them has been swift and fierce. In March, scores of soda-company employees sporting Pepsi, Coke and 7-Up gear swarmed the Kansas state senate to fight a proposal that would have added a penny in tax for each teaspoon of sugar in a nonjuice drink. That would have increased the price of a 12-oz. soda by about 10 ￠ and generated some $ 90 million in revenue a year. " I thought this is a wise choice," says state senator John Vratil, who, like counterparts across the country, has been struggling to address both a recession-induced budget gap and rising public-health costs stemming from obesity. Instead, he got an earful about how a soda tax would kill jobs, burden the poor and constitute an unwelcome government intrusion into the American diet.
    Government involvement in what Americans eat is nothing new. But why tax soda and not, say, ice cream, pizza or Oreos — or, for that matter, the video games that discourage kids from going outside to run around? Washington city-council member Mary Cheh says it’s because soda is where scientists have observed the clearest link to excess pounds. When Cheh set out to fund her Healthy Schools Act, which would raise food and physical-education standards at schools in D. C. — where about 40% of kids are overweight or obese — she didn’t know she’d wind up going after soda. But the data overwhelmed her: The amount of soda the typical American drinks has grown by roughly 500% over the past 60 years, and of the 250 to 300 calories a day Americans have, on average, added to their diets since the late 1970s,nearly half have come from sugared drinks. "I don’t want to prescribe taxes for all sorts of dietary choices, " says Cheh," but if we were going to only target one thing to make a material difference, soda would be it. "
    The tougher question is whether increasing the price of soda would, in fact, reduce the number of calories people consume. Some research indicates the answer is yes. Other research leaves room for doubt. Though studies do show that a 10% increase in the price of soda leads people to purchase about 10% less of it,that doesn’t necessarily mean folks aren’t making up for those calories elsewhere.
    How do people feel about soda taxes? In April,the Quinnipiac University Polling Institute asked residents of New York State if they supported or opposed a " fat tax" on nondiet sugared soda. Thirty-one percent were in favor, and 66% were opposed. Yet when asked if they would support such a tax if the money raised were used to fund health care, people changed their opinions dramatically, with 48% in favor and just 49% opposed.
According to Paragraph 4,scientists chose soda for taxation because______.
选项 A、they find no correlation between other food and obesity
B、soda tax is much easier to implement than other food tax
C、too much soda has been consumed in the past three decades
D、the correlation between soda and obesity is most distinct
答案C
解析 本题考查第四段具体细节。这一段介绍了“汽水税”征收的由来。本段首先提出了一个质疑，为什么对汽水而不是对冰激凌或者电子游戏征税呢?这是因为科学家发现汽水和肥胖之间的关系非常明显，因此当他们只能选择一种食品加以征税的时候，他们就选择了汽水。因此，并不代表肥胖和其他食物没有关系，只是和汽水的关系最为明显。[A]错误，[D]正确。[B]文中并未提及。[C]只是一种现象，并不是科学家征收汽水税的原因。
