【題目】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 statistics, 59 percent of American adults exercise regularly—up 12 percent from just two years ago and more than double the number 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 for 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 for races held in American cities helped fuel a strong interest in the ancient sport of running. Although Americans have also discovered other forms of exercise, running _________.

As the popularity of exercise continues to increase, so does scientific proof of its health benefits. The key to fitness is exercising the major muscle group vigorously 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 pro-duce considerable improvements in physical health in about three months.

【題目】Pulling heavy suitcases all day in the summer is hard work, especially when you are a thin 14-year-old boy. That was me in 1940-the youngest and smallest baggage boy at New York City's Pennsylvania Railway Station.

After just a few days on the job, I began noticing that the other fellows were overcharging passengers. I'd like to join them, thinking, "Everyone else is doing it."

When I got home that night, I told my dad what I wanted to do. "You give an honest day's work," he said, looking at me straight in his eye. "They are paying you. If they want to do that, you let them do that."

I followed my dad's advice for the rest of that summer and have lived by his words ever since.

Of all the jobs I've had, it was my experience at Pennsylvania Railway Station that has stuck with me. Now I teach my players to have respect for other people and their possession. Being a member of a team is a totally shared experience. If one person steals, it destroys trust and hurts everyone. I can put up with many things, but not with people who steal. If one of my players were caught stealing, he'd be gone.

Whether you're on a sports team, in an office or a member of a family. if you can't trust one another, there is going to be trouble.

【1】What can be inferred about the baggage boys?

A. They could earn much, but they had to work hard.

B. Many of them earned money in a dishonest way.

C. They were all from poor families.

D. They were thin, young boys.

【2】What does the father's advice imply?

A. It is wrong to give more to the passengers.

B. Don't believe them if they are paying you more.

C. Don't follow others to overcharge the passengers.

D. It is difficult to work hard and live as an honest boy.

【3】The writer can't put up with stealing because he thinks that _______.

A. it is a total shared experience

B. it is considered as the most dangerous

C. it does great harm to human relationship

D. it may led to the loss of his sports team.

【4】It can be concluded from the text that _______.

A. his father's advice helped him to decide which job to take up

B. working in the sports team was his most important experience

C. he learned much from his shared experience with his team members

D. his experience as a baggage boy had a great influence on his late life

【題目】Educating Girls Is a Real Lifesaver

Clare Short knows it. Every developing economist knows it. The World Bank knows it. The education of girls is the surest way to reduce poverty.

The reason is simple. All the evidence shows that taking girls out of the fields and homes, and putting them behind desks, raises economic productivity, lowers infant and maternal(產(chǎn)婦) death rates, reduces birth rates, and improves environmental management.

Why, then, are 90 million primary school-age girls around the world not in school? For the same reason that when Charles Dickens was writing David Copperfield 150 years ago girls were absent from the British education system: Men in power mostly prefer it that way, or are not interested enough in changing the situation to commit energy and money to doing so.

The countries with the poorest record for having women in positions of power or influence have the worst figures for girls’ education. High-profile intervention(介入) by organizations such as the World Bank has begun successfully with several countries, and more of the same will probably be needed to bring change in conservative, male-run states.

Even if there were no development payoff from gender equality in schools, the education of girls would still be a cause worth fighting for. Education is a human right, and the denial of it to girls is a scar on the community in the twenty-first century.

To be born a girl in a rural area in Nepal, Pakistan, Indonesia, Morocco, Togo, or Sudan — half a dozen of the most shameful performers — means being condemned to a life without school, education, or clean water, marriage and babies coming too early, too many births, children who die of preventable diseases, backbreaking work in the fields, subordination(從屬) to husband and his family, and an early death.

Every year, almost 12 million children under the age of five needlessly die of infectious diseases associated with poverty. But each additional year spent by their mothers in primary school lowers the risk of premature child deaths by about 8 percent. In Pakistan, an extra year of school for 1,000 girls could prevent sixty infant deaths.

With women and girls being the main farmers in Africa and southern Asia, their education offers a chance to develop more efficient farming practices, improve output, and raise awareness of the ecological needs of the land with tree planting and farming. Therefore, the world community cannot afford to ignore this avenue of change.

【1】Which is Not the reason why educating girls reduces poverty?

A. It improves environmental management.

B. It raises economic productivity.

C. It creates more children.

D. It lowers maternal death rates.

【2】What does the underlined word “it” in Paragraph 3 refer to?

A. The poor economy at that time.

B. Girls’ absence from school.

C. Energy and money.

D. The education of girls.

【3】Which of the following is TRUE according to the passage?

A. The countries where women have great influence and are in power always do worse in girls’ education.

B. Some organizations such as the World Bank haven’t taken the lead in girls’ education.

C. Some girls in Sudan and Indonesia are bound to live a life without education when they are born.

D. Each extra year of school for girls has nothing to do with the birthrate and maternal deaths.

【4】How many more infants will survive when 100 girls stay in school for another year?

A. 5 B. 6 C. 8 D. 12

【5】What does the author think of girls’ education?

A. essential B. terrible

C. indifferent D. helpless

【題目】Teenagers are often a difficult group. With all those hormones（荷爾蒙） flooding their bodies, they can be moody, unpredictable, and tend to make uncertain choices. But however confusing their teenage years are, kids can still be generally happy, depending on their lifestyle choices. According to a new research by British scientists, teens who don’t smoke, drink only moderately or not at all, and who don’t eat much junk food are likely to be happier than other teens.

The study looked at 40,000 British families and came up with some interesting findings. For example, kids who never drank alcohol were up to six times more likely to report higher levels of happiness than kids who drank. And teens who smoked were five times less likely to rate high on happiness charts compared to kids who don’t smoke. Same goes for diet and physical activity. The more fruits and vegetables kids eat, and the more hours they spend playing sports, the happier they are.

Now, of course this doesn’t mean that not smoking or drinking, and playing sports guarantees happiness. It could be that kids who have happy character tend to be more active and less addicted to drinking or smoking. And it could equally be the case that kids who are unhappy are more related to drinking and smoking and eating junk food.

Other studies have shown that exercise is a proven way to treat anxiety and depression. Future studies may support the idea that other healthful behaviors, including refraining(克制) from smoking, drinking, and eating too much junk, can avoid sadness and increase happiness, too.

【1】What can we learn from the text?

A. Not smoking or drinking guarantees happiness.

B. Teens with flooding hormones can not be happy.

C. Playing sports can decrease teen’s unhappiness.

D. Unhappiness can certainly result in smoking and drinking.

【2】 Which of the following might help teens quit anxiety?

A. Smoking and drinking.

B. Taking exercise.

C. Eating junk food.

D. Going on a diet.

【題目】Will Nanfang University of Science and Technology in Shenzhen announce a new beginning for China’s higher education reform? It’s too early to answer. But its presence is challenging the Ministry of Education. Even without the approval of the ministry it seems that the school is determined to move forward and enroll 50 students, so-called child prodigies(奇才), to begin classes on March l, 2011.On graduating in 2015, these students will receive a diploma unauthorized by the Ministry of Education----unlike the students of their age from the state-run universities.

The school is committed to modeling itself on Hong Kong University of Science and Technology, but if the government will not approve the school, the situation could cause a lot of trouble for those 50 students if they want to do graduate studies at other higher learning institutions. Other schools could turn their applications down for their unauthorized diplomas.

The difficulties, however, have not frightened students and their parents away. On Dec.18, 2010 more than 1,000 students and their parents visited Nanfang University of Science and Technology for interviews.

Private investment marks the school out from other higher learning institutions in the nation. Not a penny comes from the government. So the government will have no voice in how the school will be run.

The Ministry of Education has published a comprehensive plan for education reform and development between 2011 and 2020.The goal is to make China’s higher education internationally competitive. To accomplish this goal, the government should have the courage to let the educators who have big ideas try them out. The ministry should have applauded the independence. The school in Shenzhen has shown and encouraged more to do likewise.

Education reform in China has reached a new and crucial stage. Nanfang University of Science and Technology has a long way to go to prove itself competitive rather than a diploma mill.

What is the best title of the passage?

A．University of New Style.

B．China’s Education Reform.

C．Modeling Hong Kong University.

D．Authorized or Not?
