问题     In 1977, the year before I was born, a Senate committee led by George McGovern published its landmark "Dietary Goals for the United States," urging Americans to eat less high-fat red meat, eggs and dairy and replace them with more calories from fruits, vegetables and especially carbohydrates.
    By 1980 that wisdom was codified. The US Department of Agriculture (USDA) issued its first dietary guidelines, and one of the primary directives was to avoid cholesterol (胆固醇) and fat of all sorts. The National Institutes of Health (NIH) recommended that all Americans over the age of 2 cut fat consumption, and that same year the government announced the results of a $150 million study, which had a clear message: Eat less fat and cholesterol to reduce your risk of a heart attack.
    The food industry—and American eating habits—jumped in step. Grocery shelves filled with "light" yogurts, low-fat microwave dinners, cheese-flavored crackers, cookies. Families like mine followed the advice: beef disappeared from the dinner plate, eggs were replaced at breakfast with cereal or yolk-free beaters, and whole milk almost wholly vanished. From 1977 to 2012, per capita consumption of those foods dropped while calories from supposedly healthy carbohydrates increased—no surprise , given that breads, cereals and pasta were at the base of the USDA food pyramid.
    The nation was embarking on a "vast nutritional experiment," as the skeptical president of the National Academy of Sciences, Philip Handler, put it in 1980. But with nearly a million Americans a year dropping dead from heart disease by the mid-’80s, it had to try something.
    Nearly four decades later, the results are in: the experiment was a failure. Americans cut the fat, but by almost every measure, they are sicker than ever. The prevalence of Type 2 diabetes in the US increased 166% from 1980 to 2012. Nearly 1 in 10 American adults has the disease, costing the country’s health care system $245 billion a year, and an estimated 86 million people are prediabetic. Deaths from heart disease have fallen—a fact that many experts attribute to better emergency care, less smoking and widespread use of cholesterol-controlling drugs like statins—but cardiovascular (心血管的) disease remains the country’s No. 1 killer.
The author’s attitude towards nutritional experiment seems to be ______.
选项 A、ambiguous
B、suspicious
C、pessimistic
D、prejudiced
答案B
解析 根据题干中的“nutritional experiment”定位到第四段首句：The nation was embarking on a“vast nutritional experiment，”as the skeptical president of the National Academy of Sciences, Philip Handler，put it in 1980．该题同时对应第五段首句：Nearly four decades later, the results are in：the experiment was a failure．由此可见，作者对于nutritional experiment带有一点否定和质疑的态度。一般作者提到某人的观点，要么以此来证明自己的观点，要么为了否定对方的观点，很明显文章并没有对Philip Handler表示反对，由此可见作者与其态度较为一致，而他的态度为skeptical，即选项B，suspicious。
