1、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 aim of the study is to find new ways to ____. 【单选题】

5、Pronouncing a LanguagePronouncing a language is a skill. Every normal person is an expert in the skill of pronouncing his own language; but few people are even fairly proficient at pronouncing foreign languages. Now there are many reasons for this, some obvious, some perhaps not so obvious. But I suggest that the basic reason why people in general do not speak foreign languages very much better than they do native language is that they fail to understand the true nature of the problem of learning to pronounce. Far too many people fail to realize that pronouncing a foreign language is a skill----one that needs careful training of a special kind, and one that cannot be gained by just leaving it to take care of itself. I think even teachers of language, while realizing the importance of a good accent, often neglect, in their practical teaching, the branch of study concerned with speaking the language. So the first point I want to make is that English pronunciation must be taught; the teacher should be prepared to devote some of the lesson time to this, and get the student to feel that here is a matter worthy of receiving his close attention. So, there should be occasions when other aspects of English, such as grammar or spelling, are allowed for the moment to take second place.Besides this question of the time given to pronunciation, there are two other requirements for the teacher: the first, knowledge; the second, technique.It is also possible to get a clear mental picture of the relationship between the sounds of different languages, between the speech habits of English people and those, say, of your students. Unless the teacher has such a picture, any comments he may make on his students\' pronunciation are unlikely to be of much use, and lesson time spent on pronunciation may well be time wasted.According to the writer, what are teachers likely to ignore?【单选题】

A.The practical techniques of teaching

B.The importance of a good accent

C.The teaching of spelling and grammar

D.The teaching of pronunciation

正确答案:D

答案解析:从第1段第6句可知，甚至教语言的老师，即便知道好的口音的重要性，在实际教学中也常常忽略这种和语言有关的学科，因此答案是D。

6、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”。

9、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。
