1、Why Is the Native Language Learnt So Well?How does it happen that children learn their mother tongue so well? When we compare them with adults learning a foreign language, we often find this interesting fact. A little child without knowledge ｏｒexperience often succeeds in a complete mastery of the language. A grown-up person with fully developed mental powers, in most case, may end up with a faulty ａｎｄ　inexact command. What accounts fｏｒthis difference?Despite other explanations, the real answer in my opinion lies partly in the child himself, partly in the behaviｏｒof the people around him. In the first place, the time of learning the mother tongue is the most favorable of all, namely, the first years of life. A child hears it spoken from morning till night and, what is more important, always in its genuine form, with the right pronunciation, right intonation, ａｎｄ　right use of words ａｎｄ　right structure. He drinks in all the words ａｎｄ　expressions, which come to him in a flash, ever-bubbling spring. There is no resistance: there is perfect assimilation.Then the child has, as it were, private lessons all the year round, while an adult language-student has each week a limited number of hours, which he generally shares with others. The child has another advantage: he hears the language in all possible situations, always accompanied by the right kind of gestures ａｎｄ　facial expressions. Here there is nothing unnatural, such as is often found in language lessons in schools, when one talks about ice ａｎｄ　snow in June ｏｒscorching heat in January. ａｎｄ　what a child hears is generally what immediately interests him. Again ａｎｄ　again, when his attempts at speech are successful, his desires are understood ａｎｄ　fulfilled.Finally, though a child\'s "teachers" may not have been trained in language teaching, their relations with him are always close ａｎｄ　personal. They take great pains to make their lessons easy.Gestures ａｎｄ　facial expressions may assist a child in mastering his native language.【單選題】

B.Wrong

C.Not mentioned

正確答案:A

答案解析:題干大意：手勢(shì)和面部表情可能會(huì)對(duì)兒童掌握母語(yǔ)有幫助。利用答案線(xiàn)索詞gestures和facial expressions，我們可以在第三段第二句中發(fā)現(xiàn)直接相關(guān)信息。該句說(shuō)：兒童學(xué)習(xí)母語(yǔ)的另一個(gè)優(yōu)勢(shì)是可以接觸各種情景的母語(yǔ)，而且還常伴隨著正確的手勢(shì)和面部表情?？梢?jiàn)原句的說(shuō)法與問(wèn)題句一致，所以問(wèn)題句“正確”。

2、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.Among the groups studied, who had the most cases of lung cancer?【單選題】

A.Those with the lowest level of carotene intake.

B.Those with the highest level o carotene intake.

C.Those who ate only foods containing carotene.

D.Those with the lowest intake of carrots.

正確答案:A

3、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 (種類(lèi)), however. Fｏｒmore 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 -ｇｒｏｕｐteaching" ａｎｄ　"multi - age grouping" fｏｒeducational 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 ｏｒthe pressures of being skipped (超過(guò)) ahead. A youngster with a learning disability can find his ｏｒher 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.It can be learned from paragraph 2 that many parents in Nebraska ____.【單選題】

A.don\'t like centralized schools

B.come from other states

C.received education in one - room schools

D.prefer rural life

正確答案:A

4、The State of Marriage TodayIs there something seriously wrong with marriage today? During the past 50 years, the rate of divorce in the United States has exploded: almost 50% of marriages end in divorce now, ａｎｄ　the evidence suggests it is going to get worse. If this trend continues, it will lead to the breakup of the family, according to a spokesperson fｏｒthe National Family Association. Some futurists predict that in 100 years, the average American will marry at least four times ａｎｄ　extramarital affairs will be even more common than they are now.But what are the reasons fｏｒthis, ａｎｄ　is the picture really so gloomy? The answer to the first question is really quite simple: marriage is no longer the necessity it once was. The institution of marriage has been based fｏｒyears partly on economic need. Women used to be economically dependent on their husbands as they usually didn\'t have jobs outside the home. But with the rising number of women in well-paying jobs, this is no longer the case, so they don\'t feel that they need to stay in a failing marriage.In answer to the second question, the outlook may not be as pessimistic as it seems. While the rate of divorce has risen, the rate of couples marrying has never actually fallen very much, so marriage is still quite popular. In addition to this, many couples now cohabit ａｎｄ　don\'t bother to marry. These couples are effectively married, but they do not appear in either the marriage ｏｒdivorce statistics. In fact, more than 50% of first marriages survive. The statistics are deceptive because there is a higher number of divorces in second ａｎｄ　third marriages than in first marriages.So is marriage really an outdated institution? The fact that most people still get married indicates that it isn\'t. ａｎｄ　it is also true that married couples have a healthier life than single people: they suffer less from stress ａｎｄ　its consequences, such as heart problems, ａｎｄ　married men generally consider themselves more contented than their single counterparts. Perhaps the key is to find out what makes a successful marriage ａｎｄ　apply it to all of our relationships!Which of the following about marriage is NOT mentioned in the passage?【單選題】

A.There will be more relationships outside marriage.

B.Many people try to get married again after divorce.

C.Marriage has long been partly an economical need.

D.It is a fact that most people choose to get married.
