When doctors urge overweight kids to pick up more activities，reading probably isn’t what they have in mind. Yet a new study by fatness researchers at Duke University finds that the simple act of reading—depending on the choice of material—can cause weight loss in teenage girls.
The study’s experimental group included 31 fat girls aged 9 to 13，who took part in the Healthy Lifestyles Program at Duke Children’s Hospital. The girls read a novel called Lake Rescue，whose protagonist (主人公) is an overweight teenager who struggles with low selfesteem，feelings of loneliness and teasing because of her size. A group of 33 girls read a different book called Charlotte in Paris，which did not have an overweight character，and another group of 17 girls read neither book.
At the end of the sixmonth experiment，all the girls who read books had lost weight，but the girls who read Lake Rescue lost more. They lowered their body mass index (BMI) by 0.71，compared with 0.33 in the Charlotte group，an average 0.05 increase among the nonreaders.
The idea behind the study，says Dr Sarah Armstrong，director of Healthy Lifestyles，was to find a way to encourage the girls without adopting the restrictive and often authoritative voice of so many other nutrition and diet programs. Lake Rescue was the perfect instrument，says Armstrong；it presents a likable character to whom the girls could relate and whom they could learn from. As the book progresses，its protagonist learns to make healthier lifestyle choices and finds an adviser to help keep her on track. Armstrong says，“She learns that she can become healthier，and the ‘I can do it’ feeling resonates (产生共鸣) with the teenage girls.”What’s the main idea of the passage?

In the 1960s, medical researchers Thomas Holmes and Richard Rahe developed a checklist of stressful events. They appreciated the tricky point that any major change can be stressful. Bad events like "serious illness of a family member" were high on the list, but so were some helpful life-changing events like marriage.
When you take the Holmes-Rahe test you must remember that the score does not show how you deal with stress － it only shows how much you have to deal with. And we now know that the way you deal with these events dramatically (戏剧性的) affects your chances of staying healthy. By the early 1970s, hundreds of similar studies had followed Holmes and Rahe. And millions of Americans who work and live under stress worried over the reports. Somehow the research got boiled down to a memorable message. Women's magazines ran titles like "Stress causes illness".
If you want to stay physically and mentally healthy the articles said avoid stressful events. But such simplistic advice is impossible to follow. Even if stressful events are dangerous , many — like the death of a loved one — are impossible to avoid. Moreover, any warning to avoid all stressful events is a prescription (处方) for staying away from chances as well as trouble. Since any change can be stressful, a person who wanted to be completely free of stress would never marry, have a child, take a new job or move. The idea that all stress makes you sick also takes no notice of a lot of what we know about people. It supposes we' re all vulnerable and not active in the face of the difficult situation. But what about human ability and creativity? Many come through periods of stress with more physical and mental strength than they had before. We also know that a long time without change or challenge can lead to boredom and physical and mental pressure. The result of Holmes-Rahe’s medical research tells us _________________.
| A．the way you deal with major events may cause stress |
| B．what should be done to avoid stress |
| C．what kind of event would cause stress |
| D．how to deal with sudden changes in life |
The studies on stress in the early 1970s led to ___________________.

The score of the Holmes-Rahe test shows ________________.
| A．how you can deal with life-changing events |
| B．how helpful events can change your life |
| C．how stressful a major event can be |
| D．how much pressure you are under |
Why is “such simplistic advice” (Line 1, Paragraph 3) impossible to follow?

In bringing up children, every parent watches eagerly the child's acquisition (学会) of each new skill m the first spoken words, the first independent steps, or the beginning of reading and writing. It is often tempting to hurry the child beyond his natural learning rate, but this can set up dangerous feelings of failure and states of worry in the child. This might happen at any stage. A baby might be forced to use a toilet too early, a young child might be encouraged to learn to read before he knows the meaning of the words he reads. On the other hand, though, if a child is left alone too much, or without any learning opportunities, he loses his natural enthusiasm for life and his desire to find out new things for himself.
Parents vary greatly in their degree of strictness towards their children. Some may be especially strict in money matters. Others are severe (严格的) over time of coming home at night or punctuality for meals. In general, the controls represent the needs of the parents and the values of the community as much as the child's own happiness.
As regards the development of moral standards in the growing child, consistency is very important in parental teaching. To forbid a thing one day and excuse it the next is no foundation for morality (道德). Also, parents should realize that "example is better than precept". If they are not sincere and do not practice what they preach (说教), their children may grow confused when they grow old enough to think for themselves, and realize they have been to some extent fooled.
A sudden awareness of a marked difference between their parents' principles and their morals can be a dangerous disappointment. Eagerly watching the child’s acquisition of new skills, _________________.
| A．should be avoided |
| B．is universal among parents |
| C．sets up dangerous states of worry in the child |
| D．will make the child lose interest in learning new things |
In the process of children’s learning new skills, parents _________________.
| A．should encourage them to read before they know the meaning of the words they read |
| B．should expect a lot of the children |
| C．should achieve a balance between pushing them too hard and leaving them on their own |
| D．should create as many learning opportunities as possible |
The second paragraph mainly tells us that _________________.
| A．parents should be strict with their children |
| B．parental controls reflect only the values of the community |
| C．parental restrictions vary, and are not always for the benefit of the children alone |
| D．it’s parents’ and society’s duty to control the children |
The word “precept” in Paragraph 3 probably means “_________________”.
| A．opinion | B．punishment | C．behavior | D．instruction |
In terms of moral matters, parents should _____________________.
| A．follow the rules themselves |
| B．be aware of the huge difference between adults and children |
| C．forbid their children to follow hook teachings |
| D．always ensure the security of their children |
In the past ten years, America’s National Basketball Association (NBA) has grown increasingly dependent on the rest of the world to supply players.
When Michael Jordan and Larry Bird won gold in Barcelona in 1992, the Americans were praised for teaching the world how to play basketball. This season, however, 20 percent of NBA rosters（花名册） will be filled by non-Americans. NBA commissioner David Stem happily embraces the trend. On a visit to Paris in October, Stern outlined his vision for the future, which is likely to see Europe hosting NBA games by 2010.
The NBA is now planning to take China by storm.
“Our experience in China has been that it is going to be explosive in its growth,” said Stern. The strategy（战略，策略） in China is television. “We’ve made 14 deals in China with local and national networks on cable and satellite.” The success of Chinese centre Yao Ming has paved the way for the NBA marketing blitz in China. The NBA, which is broadcasted in more than 200 countries in 42 languages, will put that to the test in October 2004 when the Houston Rockets play two pre-season games against the Sacramento Kings in Beijing and Shanghai. The NBA knows that it needs a global market to compensate for tough times on home soil.
“It doesn’t matter where the players come from, all the NBA teams now know that they have to scout（寻找，觅得） internationally,” said Terry Lyons, the NBA’s vice-president of international public relations. “It has increased the level of competition here.” As Frenchman Tony Parker and Argentine Emanuel Ginobili showed in winning championship rings with the San Antonio Spurs last season, many people can earn the respect of their American peers. Others, such as the Houston Rockets’ Chinese centre Yao Ming — number one draft pick in 2002 — and the Detroit Pistons’ 18-year-old Serb Darko Milicic — number two overall in this year’s draft — are icons（偶像）in-waiting. It is the ultimate（最后的，根本的） revolution — the rest of the world teaching the US how to play basketball. According to the report, .
| A．Michael Jordan is still playing a very important role in NBA |
| B．the part played by the foreign players in NBA will be great |
| C．Yao Ming is to play two pre-season games in NBA |
| D．European countries will host the 2004 NBA games |

| B．NBA is planning to set up some training centers in China |
| C．there’ll be a big storm when NBA comes to China to play against the Sacramento Kings |
| D．the NBA’s live basket games will be broadcasted on all the TVs in China |

A. NBA is expecting more foreign players to join the league.
B. China’s rapid development in sports affects NBA.
C. Yao Ming has taken the place of Michael Jordan.

| C．The Foreign Ties That Bind the NBA |
| D．NBA Is Making Big Progress |
Even plant can run a fever, especially when they’re under attack by insects or disease. But unlike human, plants can have their temperature taken from 3, 000 feet away straight up. A decade ago, adopting the infrared （红外线）scanning technology developed for military purposes and other satellites, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress. The goal was to let farmers precisely target pesticide （杀虫剂）spraying rather than rain poison on a whole field, which invariably includes plants that don’t have pest （害虫）problems.
Even better, Paley’s Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flown at 3, 000 feet at night, an infrared scanner measured the heat emitted by crops. The data were transformed into a color-coded map showing where plants were running“fevers”. Farmers could then spot-spray, using 50 to 70 percent less pesticide than they otherwise would.
The bad news is that Paley’s company closed down in 1984, after only three years. Farmers resisted the new technology and long - term backers were hard to find. But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation. Agriculture experts have no doubt the technology works. “This technique can be used on 75 percent of agricultural land in the United States, ” says George Oerther of Texas A & M. Ray Jackson , who recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade. But only ff Paley finds the financial backing which he failed to obtain 10 years ago.Plants will emit an increased amount of heat when they are______________.
