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.Why did Dr. Shelelle think the correlation between vitamin A and lung cancer protection was logical?【单选题】

A.Vitamin A causes lung cancer.

B.Vitamin A cures lung cancer.

C.Vitamin A is necessary for the growth of the tissue lining the lungs.

D.Vitamin A is a molecule that prevents smoke from being inhaled.

正确答案:C

答案解析:根据第2段最后一句，“这种关系符合逻辑，因为维生素A对于排列在肺部呼吸通道的上皮组织结构的生长是必不可少的”。

2、I propose that we discuss this at the next meeting.【单选题】

3、A Country\'s Standard of LivingThe "standard of living" of any country means the average person\'s share of the goods and services the country produces. A country\'s standard of living, therefore, depends first on its capacity to produce wealth. "Wealth" in this sense is not money, for we do not live on money but on things that money can buy: "goods such as food and clothing", and "services" such as transport and entertainment.A country\'s capacity to produce wealth depends upon many factors most of which have an effect on one another. Wealth depends to a great extent upon a country\'s natural resources. Some region of the world are well supplied with coal and minerals, and have fertile (肥沃的) soil and a favorable climate, other regions possess none of them.Next to natural resources comes the ability to turn them to use, China is perhaps as rich as the USA in natural resources, but suffered for many years from civil and external wars, For this and other reasons it was unable to develop her resources. Sound and stable political conditions, and freedom from foreign invasions, enable a country to develop its natural resources peacefully and steadily, to produce more wealth than other country.A country\'s standard of living does not only depend upon the wealth that is produced and consumed within its own borders, but also upon what is directly produced through international trade. For example, Britain\'s wealth in foodstuffs and other agricultural ____ would be much less if she had to depend only on those grown at home. Trade makes it possible for her surplus (剩余的) manufactured goods to be traded abroad for the agricultural products which would otherwise be lacking. A country\'s wealth is, therefore, much influenced by its manufacturing capacity, providing that other countries can be found ready to accept its manufactures.【单选题】

A.organizations

B.resources

C.products

D.labors

正确答案:C

答案解析:本题有一定难度，干扰项干扰较大，要认真阅读原文。此处是说如果英国仅依靠国内生产的话，在食品和农产品上的财富就会少得多，此处要使用“产品”的含义，不是使用resources，资源，所以最佳答案是C。

4、One-Room SchoolsOne-room schools are part of the heritage of the United States, and the mention of them makes people feel a longing for "the way things were." One - room schools are an endangered species (种类), however. For more than a hundred years, one - room schools have been systematically shut down and their students were sent away to centralized schools. As recently as 1930 there were 149,000 one - room schools in the United States. By 1970 there were 1,800. Today, of the nearly 800 remaining one - room schools, more than 350 are in Nebraska. The rest are spread through a few other states that have on their road maps wide - open spaces between towns.Now that there are hardly any left, educators are beginning to think that maybe there is something yet to be learned from one - room schools, something that served the pioneers that might serve as well today. Progressive educators have come up with new names like "peer - group teaching" and "multi - age grouping" for educational procedures that occur naturally in the one - room schools. In a one - room school the children teach each other because the teacher is busy part of the time teaching someone else. The fourth grader can work at the fifth grade level in math and the third grade level in English without the bad name associated with being left back or the pressures of being skipped (超过) ahead. A youngster with a learning disability can find his or her own level without being separated from other pupils. A few hours in a small school that has only one classroom and it becomes clear why so many parents feel that one of the advantages of living in Nebraska is that their children have to go to a one - room school.What is the author\'s attitude towards one - room schools? ____ 【单选题】

A.Critical.

B.Humorous.

C.Angry.

D.Praising.

正确答案:D

答案解析:本题是态度题，有一定难度。需要认真阅读全文才能作出判断。全文只有两大段，第一段开头，作者就表达了人们对大教室学校体制的怀念和留念，第二段里，作者进一步谈了这种学校的好处，并在最后提到家长们都喜欢自己的孩子去单教室学校上课，这些阐述表明作者持赞同的态度，答案是A。

5、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,____ 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 raise 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.strangely

B.unusually

C.approximately

D.actually

正确答案:D

答案解析:actually:事实上、实际上。根据上下文可以得知，此处应为“实际上阻碍了经济发展”，因此答案为D。strangely:奇怪地；unusually:不寻常地；approximately:大约。

6、J. K. RowlingLike that of her own character, Harry Potter, J. K. Rowling\'s life has the luster of a fairy tale.

7、Operatunity1. Operatunity is a TV talent show for amateur opera singers, The winners get the chance to sing with the English National Opera. When two housewives, Denise Leigh and Jane Gilchrist won in 2002, their lives changed forever, As they sang Verdi\'s Rigoletto at the Coliseum (音乐厅) in Rome, they were transformed from working mothers into opera celebrities (名人).2. "I live in the village I was born in," says Denise, who is blind. "Lots of my neighbours are family, and my life is all about my three children. Jane, who worked as a cleaner and a shop assistant, was in a similar situation." She says.

Even when they won the competition they were allowed to tell their close family but they weren\'t allowed to tell anyone else until later. Denise and Jane also found the travelling is difficult. They couldn’t take their children with them while they were away singing, so they had to organise childcare. However, there\'s been no problem with the physical side of singing: "We didn\'t have to worry about that as we\'ve had lots of help and wonderful voice training." says Jane. They also had to learn to deal with the media."

8、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. ”

9、Life at Aichi UniversityI\'m Yamamoto Mika, a 22 years old Japanese girl. I\'d like to invite you to Aichi University so you can understand my life.Our university has a close relationship with China and my department is the only one of its kind in Japan. My courses include the Chinese language, modern Chinese politics and economics. I love Chinese culture and I have been to Tianjin as an exchange student.In Japan, our courses are divided into compulsory, optional and specialized courses. However, we have a flexible schedule. We can choose classes from a wide range of options.Many students finish the compulsory courses in three years so that they can have one year without any classes. They often use this period of time to study abroad, conduct research and travel. Many students even suspend their study for additional study - abroad opportunities,Japanese universities encourage students to choose their own ways of study, so it is quite easy for us to apply for study suspension.Japanese students participate in various kinds of extracurricular (课外的) activities. They attend clubs from elementary schools, so many students have already been accustomed to clubs when they enter university.Our university now has 42 art clubs and 45 sports clubs. The annual University Festival is the grandest carnival (狂欢节) of Japanese universities. In the festival, students promote their clubs and organize various activities. Our university\'s festival attracted about 150,000 people last year. I really like this festival.When we promote our clubs, we cook "tonnjiru", a kind of pork soup, and sell it to other students at the fair.We also go to different places to interview celebrities (名人) who attend our festival as guests. It is a wonderful experience to talk to those stars face to face.Japanese students like to hold parties. We have two kinds of parties. One is the Mochivori party. If you want to attend this party you have to cook something and take it to the party. The organizer buys drinks and snacks.The other kind of party is the Nomikai, which mainly involves alcohol. We drink something called chu - hai, which is a combination of soda and wine. We also drink Japanese sake (日本米酒) and beer. There are parties for many occasions, like welcoming new students, celebrating victories and birthday parties or just for promoting friendship.Which of the following is NOT a feature of the University Festival? ____【单选题】

A.Organizing various activities.
