America is a country on the move. In unheard of numbers, people of all ages are exercising  their way to better health. According to the latest figures, 59 percent of American adults exercise regularly-up 12 percent from just two years ago and more than double the figure of 25 years ago. Even non-exercisers believe they would be more attractive and confident if they were more active.

It is hard not to get the message. The virtues of physical fitness are shown on magazine covers, postage stamps, and television ads of everything from beauty soaps to travel books. Exercise as a part of daily life did not catch on until the late 1960s when research by military doctors began to show the health benefits of doing regular physical exercises. Growing publicity (宣傳) for races held in American cities helped fuel a strong interest in the ancient sport of running. Although running has leveled off in recent years as Americans have discovered equally rewarding—and sometimes safer-forms of exercise, such as walking and swimming, running remains the most popular form of exercise.

As the popularity of exercise continues to mount, so does scientific evidence of its health benefits. The key to fitness is exercising the major muscle groups vigorously (強有力地) enough to approximately double the heart rate and keep it doubled for 20 to 30 minutes at a time. Doing such physical exercises three times or more a week will produce considerable improvements in physical health in about three months.

1.It can be learnt from the passage that the health benefits of exercise ___________.

A．are to be further studied

B．are yet to be proved

C．are self evident

D．are supported by scientific evidence

2.A growing interest in sports developed after ______________.

A．an increasing number of races were held in American cities

B．research showed their health benefits

C．scientific evidence of health benefits was shown on TV ads

D．people got the message from magazine covers and postage stamps

3.Which of the following would be the best title for the passage?

A．Running—A Popular Form of Sport

B．Scientific Evidence of Health Benefits

C．Different Forms of Exercise

D．Exercise—The Road to Health

4.Which of the following is closest in meaning to the phrase “l(fā)eveled off” in the paragraph 2?

A．“reached its lowest level in popularity”

B．“stopped being popular”

C．“stopped increasing in popularity”

D．“become very popular”

 

【答案】

1.C

2.B

3.D

4.B

 【解析】

1.D推理判斷題。第三段首句“… so does scientific evidence of its health benefits”表明鍛煉人數(shù)在不斷增加，而鍛煉有益于健康的科學依據(jù)也在不斷增加，即鍛煉有益于健康是得到科學依據(jù)支持的。

2.B細節(jié)理解題。根據(jù)第二段“…When research by military doctors began to show the health benefits of…”，可知B項正確。

3.A文章標題題。作者論述了體育鍛煉的益處、方式及適當?shù)倪\動量，表明要有健康的身體就得運動、鍛煉。故A項正確。

4.C詞義理解題。第二段指出宣傳使人們提高了對跑步的興趣，后來人們發(fā)現(xiàn)其他形式的鍛煉同樣有益于健康，有時更加安全些，于是“跑步”這種運動形式才“l(fā)evel off”，同時指出雖然“l(fā)evel off”但仍然是the most popular form，由此可知“l(fā)evel off”應是“stop climbing (increasing in popularity)”，故C項正確。

Who are these people rushing by you in the street? More than 215 million people now call America “home’’, but most of them can trace their families back to other parts of the world. If you look at the names on shop windows, you will see that Americans come from many different lands. The idea that these people, who once were strangers to the United States, have lost the customs and cultures of their original countries and have become “American’’is really not true. In fact, what exists in America is more often a kind of “side-by-side”, living in which groups of people from other countries often have kept many of their customs and habits. They join the general American society only in certain areas of their lives—such as in schools, business, and sports-but they keep many of their own native customs and manners socially and at home. This living “side-by-side” has both advantages and disadvantages. Sometimes it may cause disagreements to develop between groups whose ways of life are very different from one another. However, there are also great advantages that come from the variety of cultures brought by settlers from other lands. There is great freedom of choice among ideas and dress, food, and social customs in America. Everyone can find some part of his or her familiar world in the United States, in Churches, music, food, national groups, or newspapers.

1.More than 215 million people call America “home” because          .

A. they buy their houses there   B. they settle there now

C. they get married there       D. they were born there

2.“Side-by-side” living style means        .

A. making friends with native people

B. the groups of people who live nearby

C. keeping their own customs while sharing American ones in certain areas

D. that they get closer to American society

3.According to the passage, people in the USA       .

A. share American customs and culture

B. 1ive in a kind of “side-by-side'' society

America is a mobile society. Friendships between Americans can be close and real, yet disappear soon if situations change. Neither side feels hurt by this. Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while — then no more. If the same two people meet again by chance, even years later, they pick up the friendship. This can be quite difficult for us Chinese to understand, because friendships between us develop more slowly but then may become lifelong feelings, extending (延伸) sometimes deeply into both families.

Americans are ready to receive us foreigners at their homes, share their holidays, and their home life. They will enjoy welcoming us and be pleased if we accept their hospitality (好客) easily.

Another difficult point for us Chinese to understand Americans is that although they treat  us warmly in their personal everyday lives, they don’t show their politeness to us if it requires a great deal of time. This is usually the opposite of the custom in our country where we may be generous with our time. Sometimes, we, as hosts, will appear at airports even in the middle of the night to meet a friend. We may take days off to act as guides to our foreign friends. The Americans, however, express their welcome usually at homes, but truly can not manage the time to do a great deal with a visitor outside their daily routine. They will probably expect us to get ourselves from the airport to our own hotel by bus. And they expect that we will phone them from there. Once we arrive at their homes, the welcome will be full, warm and real. We will find ourselves treated hospitably.

For the Americans, it is often considered more friendly to invite a friend to their homes than to go to restaurants, except for purely business matters. So accept their hospitality at home!

1.Which of the following statements is TRUE according to the passage?

A．Friendships between Americans usually extend deeply into their families.

B．Friendships between Americans usually last for all their lives

C．Americans always show their warmth even if they are very busy.

D．Americans will continue their friendships again even after a long break.

2.From the last two paragraphs we can learn that when we arrive in America to visit an American friend, we will probably be ______.

A．warmly welcomed at the airport            B．offered a ride to his home

C．treated hospitably at his home              D．treated to dinner in a restaurant

3.The underlined words “generous with our time” in Paragraph 3 probably mean ______.

A．willing to spend time                     B．serious with time

C．careful with time                        D．strict with time

4.A suitable title for this passage would probably be “______”.

A．Friendships between Chinese              B．Friendships between Americans

C．Americans’ hospitality                  D．Americans’ and Chinese’s views of friendships

請認真閱讀下列短文, 并根據(jù)所讀內容在文章后表格中的空格里填入最恰當?shù)膯卧~。注意：每空格1個單詞。

The job of raising children is a tough one. Children don't come with an instruction handbook. And each child is different. So parents sometimes pull their hair out in frustration, not knowing what to do. But in raising children---as in all of life---what we do is influenced by our culture. Naturally then, American parents teach their children basic American values.

    To Americans, the goal of parents is to help children stand on their own two feet. From infancy, each child may get his or her own room. As children grow, they gain more freedom to make their own choices. Teenagers choose their own forms of entertainment, as well as the friends to share them with. When they reach young adulthood, they choose their own careers and marriage partners. Of course, many young adults still seek their parents' advice and approval for the choices they make. But once they "leave the nest" at around 18 to 21 years old, they want to be on their own, not "tied to their mother's apron strings."

   The relationship between parents and children in America is very informal. American parents try to treat their children as individuals ─ not as extensions of themselves. They allow them to fulfill their own dreams. Americans praise and encourage their children to give them the confidence to succeed. When children become adults, their relationship with their parents becomes more like a friendship among equals. But contrary to popular belief, most adult Americans don't make their parents pay for room and board when they come to visit. Even as adults, they respect and honor their parents.

    Most young couples with children struggle with the issue of childcare. Mothers have traditionally stayed home with their children. In recent years, though, a growing trend is to put preschoolers in a day care center so Mom can work. Many Americans have strong feelings about which type of arrangement is best. Some argue that attending a day care center can be a positive experience for children. Others insist that mothers are the best caregivers for children. A number of women are now leaving the workforce to become full-time homemakers.

    Disciplining children is another area that American parents have different opinions about. Many parents feel that an old-fashioned spanking(一頓打) helps youngsters learn what "No!" means. Others prefer alternate forms of discipline. For example, "time outs" have become popular in recent years. Children in "time out" have to sit in a corner or by a wall. They can get up only when they are ready to act nicely. Older children and teenagers who break the rules may be grounded, or not allowed to go out with friends. Some of their privileges at home like TV or telephone use may also be taken away for a while. Although discipline isn't fun for parents or children, it's a necessary part of training.

Being a parent is a tall order. It takes patience, love, wisdom, courage and a good sense of humor to raise children. Some people are just deciding not to have children at all, since they're not sure it's worth it. But raising children means training the next generation and preserving our culture. What could be worth more than that?
