1、A Carrot a Day Keeps Cancer AwayAmong all the malignancies, lung cancer is the biggest killer: more than 100,000 Americans a year die of the disease. Giving up smoking is one of obvious way to reduce the risk, but another answer may lie in the kitchen. According to a new report, even heavy smokers may be protected from developing lung cancer by a simple dietary measure: a daily portion of carrots, spinach ｏｒany other vegetable ｏｒfruit containing a form of vitamin A called carotene.The finding, published in the British medical journal The Lancet, is part of a long-range investigation of diet ａｎｄ　disease. Since 1957 a team of American researchers has monitored the dietary habits ａｎｄ　medical histories of 2,000 middle-aged men employed by the Western Electric Co. in Chicago. Led by Dr. Richard Shelelle of Chicago\'s Rush-Presbyterian, St. Luke\'s Medical Center, the researchers recently began to sort out the links between the subjects\' dietary patterns ａｎｄ　cancer. Other studies of animals ａｎｄ　humans have suggested that vitamin A offers some protection against lung cancer. The correlation seemed logical, since vitamin A is essential fｏｒthe growth of the epithelial (上皮的) tissue that lines the airways of the lungs.Vegetables: But the earlier research did not distinguish between two different forms of the vitamin. "Preformed" vitamin A, known as retinol, is found mainly in liver ａｎｄ　dairy products like milk, cheese, butter ａｎｄ　eggs. But vitamin A is also made in the body from carotene, which is abundant in a variety of vegetables ａｎｄ　fruits, including carrots, spinach, squash, tomatoes, sweet potatoes ａｎｄ　apples.In the Western Electric study, Shekelle ａｎｄ　his colleagues found little correlation between the incidence of lung cancer ａｎｄ　the consumption of foods containing preformed vitamin A, but when they examined the data on carotene intake, they discovered a significant relationship. Among the488 men who had the lowest level of carotene consumption, there were fourteen cases of lung cancer, in aｇｒｏｕｐof the same size that ate the most carotene, only two cases developed. The apparent protective effect of carotene held up even fｏｒlongtime smokers but to a lesser degree.Further studies will be necessary before the link between lung cancer ａｎｄ　carotene can be firmly established. In the meantime, researchers warn against taking large numbers of vitamin A pills, because the tablets contain a form of the chemical that can be extremely toxic in high doses. Instead, they advise a well-balance diet that includes foods rich in carotene. Fｏｒa smoker, a half-cup of carrots every day might possibly make the difference between life ａｎｄ　death.Where is carotene present?【单选题】

A.tomatoes

B.carrots

C.squash

D.all of the above

正确答案:D

答案解析:根据第3段，“维生素A在体内的产生源于胡萝卜素，胡萝卜素在蔬菜、水果中大量存在，包括胡萝卜、菠菜、西葫芦、西红柿和苹果”。因此答案是D。

2、J. K. RowlingLike that of her own character, Harry Potter, J. K. Rowling\'s life has the luster of a fairy tale. Divorced, living on public assistance in a tiny Edinburgh flat with her infant daughter, Rowling wrote Harry Potter ａｎｄ　the Sorcerer\'s Stone at a table in a cafe during her daughter\'s naps ａｎｄ　it was Harry Potter that rescued her.Rowling remembers that she always wanted to write ａｎｄ　that the first story she actually wrote down, when she was five ｏｒsix, was a story about a rabbit called Rabbit.

He attends a school fｏｒwizardry -she could see him very plainly in her mind. _____ four hours later, many of the characters ａｎｄ　the early stages of the plot were fully formed in her head. The story took further shape as she continued working on it in pubs ａｎｄ　cafes over her lunch hours.Rowling was working as a French teacher when she heard that her book about the boy wizard had been accepted fｏｒpublication. Harry Potter ａｎｄ　the Philosopher\'s Stone was published in June1997 ａｎｄ　achieved almost instant success. With the publication of the American edition, retitled Harry Potter ａｎｄ　the Sorcerer\'s Stone, in 1998, Rowling\'s books continued to make publishing history. Harry Potter climbed to the top of all the bestseller lists fｏｒchildren\'s ａｎｄ　adult books. In Britain a separate edition of the first book appeared with a more "adult" dust jacket so that grown-ups reading it on trains ａｎｄ　subways would not have to hide their copy behind a newspaper.J. K. Rowling lives in Edinburgh, Scotland, with her daughter Jessica ａｎｄ　continues to work on writing the seven-book story of Harry Potter. 【单选题】

5、Gun Rights in the USImmediately after the shooting at Virginia Tech University, Americans gathered to mourn (致哀) the dead. The president ａｎｄ　the state governer both hurried there to share the grief. But the majority of Americans still cling to their right to own weapons.Strictly speaking, the US is not the only country here gun violence has destroyed lives, families ａｎｄ　communities in everyday circumstance. But the US is one of the few countries that seem unwilling ａｎｄ　politically incapable of doing anything serious to stop it.In countries like Britain ａｎｄ　Canada, the government adopted strict gun control soon after serious gun violence incidents. US leaders, however, are held hostage by the gun lobby (院外活动集团) ａｎｄ　the electoral (选举) system.The powerful National Rifle Association, the majｏｒsupporter of gun rights in the US, is too strong fｏｒany party to take on. Most Republicans oppose gun control anyway. Over the years, the Democrats have found that they can either campaign fｏｒgun control ｏｒwin power, not both, they prefer power.According to the US Bureau of Justice Statistics, firearm (火器) incidents accounted ____ nine percent of the 4.7 million violent crimes in 2005. So although opinion polls show most Americans want stricter gun laws, many people don\'t want to give up their arms they keep to protect themselves.Dave Hancock, a Virginia gun lover, is one example. In an interview he said, "If one professｏｒin the Virginia incident had been carrying a legal weapon, they might have been able to stop all this. "In his opinion, the massacre (大屠杀) is an argument fｏｒmore people to carry weapons, not fewer.Americans\' clinging to the right to bear arms is not just a fear of crime, but a mistrust of government, commented UK\'s Guardian newspaper.One Virginia resident, who had a permit to carry a concealed (隐藏的) firearm, told the Guardian that it was every American\'s responsibility to have a gun."Each person," he said, "should not rely solely on the government fｏｒprotection."【单选题】
