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 or any other vegetable or fruit 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 for the 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 a group of the same size that ate the most carotene, only two cases developed. The apparent protective effect of carotene held up even for longtime 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. For a 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、Fighting for a Brighter Future for WomenWhen I was asked what it means to be a woman running for president, I always gave the same answer that I was proud to be running as a woman, but I was running because thought I\'d be the best president.But I am a woman and, like millions of women, I know there are still barriers and biases (偏见) out there, often unconscious, and I want to build an America that respects and embraces the potential of every last one of us.I ran as a daughter who benefited from opportunities my mother never dreamed of. I ran as a mother who worried about my daughter\'s future and a mother who wants to leave all children brighter tomorrows.To build that future I see, we must make sure that women and men understand the struggles of their grandmothers and their mothers, and that women enjoy equal opportunities, equal pay, and equal respect.Let us resolve and work toward achieving very simple propositions (命题): there are no acceptable limits, and there are no acceptable prejudices in the 21 st century in our country.You can also be so proud of it, from now on, it will be unremarkable for a woman to win primary state victories, unremarkable to let a woman in a close race to be our nominee (被提名者), unremarkable to think that a woman can be the president of the United States. And this is truly remarkable my friends.We are disappointed that we couldn\'t go all of the way, especially the young people who put so much into this campaign. It would break my heart if, in falling short of my goal, I in any way discouraged any of you from pursuing yours.We always aim high, work hard, and care deeply about what you believe in. And when you stumble (绰倒), keep faith. And, when you\'re knocked down, get right back up and never listen to anyone who says you can\'t or shouldn\'t go on.As we gather here today in this historic, magnificent building, the 50th woman will leave the Earth and orbit (绕轨道运行) overhead. If we can blast 50 women into space, we will someday launch a woman into the White House.Hillary Clinton believed that if she were elected president of the United States, she would be the best.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:A

答案解析:本题的难度不大，答案依据就在文章第一段。第一段最后一句谈到，我参加竞选是因为我相信我会是最棒的总统，所以本题正确，答案是A。

3、U. S. to Start $3. 2 Billion Child Health Study in JanuaryA study that will cost $3. 2 billion and last more than two decades to track the health of100,000 U. S. children from before birth to age 21 will be launched in January, U. S. health officials said on Friday.Officials from the U. S. government\'s National Institutes of Health said they hope the study, to be conducted at 105 locations throughout the United States, can help identify early-life influences that affect later development, with the goal of learning new ways to treat or prevent illness.The study will examine hereditary and environmental factors such as exposure to certain chemicals that affect health.Researchers will collect genetic and biological samples from people in the study as well as samples from the homes of the women and their babies including air, water, dust and materials used to construct their residences, the NIH said.Officials said more than $200 million has been spent already and the study is projected to cost$3. 2 billion."We anticipate that in the long term , what we learn from the study will result in a significant savings in the nation\'s health care costs," Dr. Duane Alexander, who heads the NIH\'s Eunice Kennedy Shriver National Institute of Child Health and Human Development, told reporters.The study will begin in January when the University of North Carolina and the Mount Sinai School of Medicine in New York start signing up pregnant women whose babies will then be followed to age 21.Some of the early findings will be about factors behind pre-term birth, which has become more common in recent years, according to Dr. Peter Scheid of the NIH, who heads the study.The people taking part will be from rural, urban and suburban areas, from all income and educational levels and from all racial groups, the NIH said.The babies of the participants will be followed____.【单选题】

A.throughout their lives.

B.for more than two decades.

C.from birth to 21 months.

D.until they get married.

正确答案:B

答案解析:短文的第1段以及倒数第3段都说到，这些婴儿将从出生前一直被跟踪到21岁。

4、RobotsThe most sophisticated (先进的) Japanese robots, which have vision systems and work at very high speeds, are still based on American designs. Studies of robots, particularly computer control software, are considered to be generally less advanced in Japan than in America or Europe.Although industrial robots were originally developed as devices for simply handling objects, today their commonest uses are for more skilled work like welding (焊接), spray-painting and assembling components.In Britain robot sales appropriately peaked in 1984, but have been declining ever since. This is partly because British wage rates are too low to make robots financially attractive and partly because engineers now have more experience with robots and are more aware of the difficulties of introducing them effectively.It has been calculated that a robot uses on average about 100 times more energy than a human to do an equivalent job.It is estimated that 20% of all comic book heroes in Japan are robots. This is an enormous number because comics are so popular that they make up a third of all material published in Japan. The reliability of robots is measured in their MTBF or mean time between failures. This has risen from about 250 hours in the mid-1970s to about 10,000 hours today (equivalent to working 18 hours a day for two years). One way robot manufacturers have increased reliability is to test every single component they buy, instead of the normal procedure of just testing a small .sample.The biggest single benefit of introducing robots claimed by Japanese companies is that they increase quality control. One programmed robots can work more accurately and consistently than humans, who can get tired and bored.Paragraph 2 ________.【单选题】

A.Ongoing Research

B.Extension of Use

C.Robot Heroes

D.Greater Reliability

E.Falling Demand

F.Hidden Danger

正确答案:B

答案解析:第二段只有一句话，该句讲述了机器人从最初被用于简单的机械操作发展到今天普遍应用于技术含量更高的工作，如焊接、喷漆等。这表明机器人应用的领域更加广泛。B选项Extension of Use与其意思相符，故B为正确答案。

6、A Strong Greenhouse Gas1 Methane is a colorless, odorless gas; it is also a potent greenhouse gas, and once released into the atmospheres, it absorbs beat radiating from Earth\'s surface. That\'s why methane is a major contributor to the planet\'s increasing temperature rise or global warming. Molecule for molecule, methane\'s heat-trapping power in the atmosphere is 21 times stronger than carbon dioxide, the most abundant greenhouse gas.2 With 13 billion cows belching almost constantly around the world (100 million in the U. S. alone), it\'s no surprise that menace released by livestock is one of the chief sources of the gas. Other prime methane sources: petroleum, drilling, coal mining, solid-waste landfills and wetlands.3 Greenhouse gases like methane and carbon dioxide make up only a small part of Earth\'s atmosphere, which is 78 percent nitrogen and nearly 21 percent oxygen. And without greenhouse gases to trap the sun\'s heat and warm the planet, life as we know it couldn\'t exist. But in the last200 years, human activity that requires burning oil, natural gas, and coal for energy has magnified the greenhouse effect.4 Atmospheric concentrations of methane have more than doubled in the last two centuries. Blame for this often focuses on big industries and gas-guzzling vehicles. But agriculture plays a major role, too. In the past 40 years alone, the global cattle population has doubled.5 Cows munch mostly grasses and hay yet they grow big and hefty. Why? Because of the rumen. The rumen holds 160 liters of food and billions of microbes. These microscopic bacteria and protozoa break down cellulose and Fiber into digestible nutrients. A cow couldn\'t live without its microbes. As the microbes digest cellulose, trey release methane. The process occurs in all animals with a rumen (cows, sheep, and goats, for example), and it makes them very gassy. It\'s part of their normal digestion process. When they drew their cud, they regurgitate some food to rechew it, and all this gas comes out. The average cow expels 600 liters of methane a day.That\'s why we say livestock gas is also a major factor of causing the global warming.Paragraph l ____【单选题】

A.Life of Macroscopic Bacteria in Livestock\'s Rumen

B.Ways to Reduce Methane\'s Heat-trapping Power

C.Agriculture Also Contributes to Increased Concentrations of Methane in the Atmosphere

D.Why Livestock Releases Methane

E.Methane as a Strong Greenhouse Gas

F.Livestock as a Prime Factor of the Greenhouse Effect

正确答案:E

答案解析:本段的第3句点出了“methane\'s heat-trapping power in the atmosphere is 21 times stronger than carbon dioxide. ”

7、Preparations for InterviewThe first thing you have to prepare for a job interview is to write your resume. Most of all, the resume should emphasize all the related experience you have had.

9、Indian\'s NamesEach Indian was supposed to keep his birth name until he was old enough to earn one for himself. But his playmates would always give him a name of their own. No matter what his parents called him, his childhood friends would use the name they had chosen. Often it was not pleasing, such as Bow Legs or Bad Boy. But sometimes a name fit so well that the youngster found it difficult to shake it off. If he could not earn a better one from a war later, he could be stuck with a name like Bow Legs for the rest of his life.The Indian earned his real name when he was old enough for his first fight against the enemy. His life name depended on how he acted during this first battle. When he returned from the war, the whole tribe would gather and observe the ceremony in which he would be given his name by the chief. If he had done well, he would get a good name. Otherwise he might be called Crazy Wolf or Man-Afraid-of-a Horse. So an Indian\'s name told his record or described the kind of man he was.A man was given many chances to improve his name, however, if in a later battle he was brave in fighting against the enemy, he was given a better name. Some of our great fighters had as many as twelve names, all good and each better than the last.An Indian\'s names belonged to him for the rest of his life. No one else could use them. Even he himself could not give them away because names were assigned by the tribe, not the family. So no man could pass on his name unless the chief and the tribe asked him to do so.Sometimes an Indian would be asked to give his name to a son who had performed a noticeable deed. I know of only three or four times when this happened. It is the rarest honor for a person -the honor of assuming his father\'s name.Why names were important to an Indian?【单选题】

A.Because they were given by the chief of the tribe.

B.Because they described the character of a man.

C.Because he got his names from the older generation.

D.Because names were earned in battle.

正确答案:B

答案解析:第2段最后一句：名字告诉我们他的记录或者表明这是一个什么样的人，因此选B。

10、Woman workThough some people have suggested that women should return to housework in order to leave more jobs for men, the idea has been rejected by both women and men in public opinion polls.Lately some union officials have suggested that too many women are employed in types of work more suitable for men and that women should step aside to make way for unemployed young men. They argue that women, especially women in their childbearing years,actually delay economic development and result in productivity, poor quality and inefficiency.To solve the problem, they suggested that working women stay at home while their husbands or brothers were given double wages. They argue that under these circumstances, families would remain their same level of income, and women could run the house and ____ children much better,The suggestion, however , has been flatly rejected by 9 0ut of 10 people polled .Some other people have suggested another way called "phased employment" theory. The theory suggests that a woman worker take leave from her job when she is seven months pregnant and stay off the job until her baby reaches the age of 3. It suggested that women on leave receive 75 percent of their normal salary and be allowed to return to work after the three-year period. This will benefit children, women, their families and the society and it definitely seems to be more acceptable than the suggestion that women return to their homes forever.【单选题】

A.grow

B.bring

C.raise

D.feed

正确答案:C

答案解析:抚养孩子一定要用raise; grow:种植、成长；bring后面加上up才有“抚养”的意思；feed:喂养。因此答案是C。
