单选题 Excessive sugar has a strong real-effect on the functioning of active organs such as the heart, kidneys and the brain. Shipwrecked sailors who ate and drank nothing but sugar for nine days surely went through some of this trauma.
This incident occurred when a vessel carrying a cargo of sugar was shipwrecked in 1793. The five surviving sailors were finally rescued nine days after the accident. They were in a wasted condition due to starvation, having consumed nothing but sugar. French physiologist F. Magendie was inspired by that incident to conduct a series of experiments with animals. In the experiments, he fed dogs a diet of sugar and water. All the dogs wasted and died.
The shipwrecked sailors and the French physiologist's experimental dogs proved the same point. As a steady diet, sugar is worse than nothing. Plain water can keep you alive for quite some time. Sugar and water can kill you. Humans and animals are "unable to subsist on a diet of sugar". The dead dogs in Professor Magendie's laboratory alerted the sugar industry to the hazards of free scientific inquiry. From that day to this, the sugar industry has invested millions of dollars in behind-the-scenes, subsidized science. The best scientific names that money could buy have been hired, in the hope that they could one day come up with something at least pseudoscientific in the way of glad tiding about suger.
It has been proved, however, that sugar is a major factor in dental decay; sugar in a person's diet does cause overweight; removal of sugar from diets has cured symptoms of crippling, worldwide diseases such as diabetes, cancer and heart illnesses.
Sir Frederick Banting noticed in 1929 that, among sugar plantation owners who ate large amounts of their refined stuff, diabetes was common. Among native cane-cutters, who only got to chew the raw cane, he saw no diabetes.
However, the story of the public relations' attempts on the part of the sugar manufacturers began in Britain in 1808 when the Committee of West India reported to the House of Commons that a prize of twenty-five guineas had been offered to anyone who could come up with the most "satisfactory" experiments to prove that unrefined sugar was good for feeding and fattening oxen, cows, hogs and sheep.
Food for animals is often seasonal, always expensive. Sugar, by then, was dirt cheap. People weren't eating it fast enough. Naturally, the attempt to feed livestock with sugar in England in 1808 was a disaster.

单选题 The word "trauma" (Para. 1) most probably means
A. diseased condition. B. dangerous situation.
C. terrible shipwreck. D. excessive sugar intake.
【正确答案】 A
【答案解析】[解析] 含义题。根据题干定位到第一段。被考查词所在句意为“失事船只上的水手9天之中只吃糖,他们肯定会经受这类______”。而上一句提到,吃糖过量会对心脏、肾、大脑等活性器官的功能产生很强的破坏作用。推断可知,水手们吃了9天的糖很可能有活性器官受损的情况,所以A项“患病情况”正确。B项“危险的情况”、C项“可怕的船只失事”和D项“摄入过多的糖”均不符合文意。
单选题 Sugar manufacturers have
A. tried to make experiments on their own with sugar on humans and animals.
B. invested millions of dollars in buying best names of scientists to sell sugar.
C. hoped to encounter some scientific findings about sugar.
D. tried to establish public relations in order to open the market for sugar.
【正确答案】 D
【答案解析】[解析] 细节题。本题可采用排除法。文章第二段提到在狗身上做了有关糖的实验,原文并没有提到在人身上做实验,故排除A项;第三段最后提到,制糖厂商聘用了能用钱请到的最好的科学家,以期望有朝一日能得到有关糖的好消息,哪怕是伪科学的消息。由此可知,他们并没有买下最好的科学家的名字,也没有希望找到有关糖的科学发现,故排除B项和C项;最后一段开始提到,制糖厂商试图建立公共关系的举动早在1808年的英国就出现了,结合下文提到的厂商倡导用糖当作牲畜饲料推断可知,制糖厂商曾尝试过建立公共关系,以便打开糖的销路,故D项正确。
单选题 The sugar manufacturers have invested heavily in behind-the-scenes, subsidized science because they
A. began to realize the benefits of scientific experiments.
B. began to realize the hazards of eating sugar.
C. were afraid that the trade of sugar would be prohibited by the government.
D. hoped to find something pleasing, even in the guise of science, about sugar.
【正确答案】 D
【答案解析】[解析] 细节题。根据题干定位到第三段。最后两句指出,制糖厂商投资数百万美元资助幕后科学研究,他们聘用了能用钱请到的最好的科学家,以期望有朝一日能够得到有关糖的好消息,哪怕是伪科学的消息,由此推断,制糖厂商在幕后科学研究上投入大量金钱,是因为他们希望能得到有关糖的可喜消息,哪怕是在科学的伪装之下,所以D项正确。其他三项文章都没有提及。
单选题 Which of the following is true about sugar?
A. Refined sugar alone cannot be a diet for people to live on for a few days.
B. Sugar can cause fever, diabetes, cancer and heart diseases.
C. Unrefined sugar was once forbidden to be used to feed and fatten livestock.
D. Sugar cannot be used as a daily diet.
【正确答案】 D
【答案解析】[解析] 细节题。本题可采用排除法。第一段提到,失事船只上的水手单靠吃糖度过了9天,可见细砂糖还是可以当作食物维持几天生命的,故排除A项;第四段提到,吃糖可能导致超重、糖尿病、癌症、心脏病等,但并未提到会导致发烧,故排除B项;最后一段提到,粗糖曾经被用于饲养牲畜,但原文并未提到曾禁止用粗糖饲养牲畜,故排除C项;根据第四段提及的糖可能引发的种种疾病可知,糖是不可以作为日常主食的,故D项正确。
单选题 We can safely conclude that
A. people in the 19th century were eager to eat sugar.
B. if those shipwrecked sailors had drunk fresh water, things would have been even worse.
C. one or more scientists have been hired to cheat in the experiments of sugar.
D. scientists can do nothing without the money subsidized secretly.
【正确答案】 B
【答案解析】[解析] 推断题。本题也可采用排除法。文中并未提及人们在19世纪热衷于吃糖,故排除A项;第三段提到,光喝水可以使生命维持一段时间,而同时吃糖、喝水则会要人命。由此推断,如果失事船只上的那些水手除了吃糖之外,还喝了淡水,他们很可能就死了,故B项正确;第三段提到,制糖厂商在幕后支持科学研究,他们希望能得到与糖有关的可喜消息,哪怕是伪科学的消息,但原文并未提到有科学家受聘在对糖所做的实验中进行欺骗,故排除C项:原文没有提到如果没有得到秘密资助,科学家就无能为力,故排除D项。
