Obesity(肥胖) in children and adolescents is rising at an alarming rate. Currently over 15% of young people over 6 years old are obese, and obesity is also increasing among children aged 5 and younger.
Children are considered to be overweight if the BMI(Body Mass Index) is over 85% of the weight group in their age and sex categories. If it is 95% and over, they are considered to be obese. Adolescents are generally judged according to adult criteria(标准) for obesity, although there are other considerations in this population, for many factors will affect the result of these measurements.
Causes and Risk Factors for Obesity in Children
Lifestyle Factors. Without educational or parental guidance, children are extremely greatly exposed to the cultural pressures that are largely responsible for growth of the obesity. Neither the media nor the educational system has strong programs that encourage healthy way of life, including exercise and healthy foods. The following are some specific problems created by the culture:
﹡Too much television watching plays an important role in obesity in children. Not only is it a passive activity, but television also offers countless temptations(诱惑) with its advertisements for fast foods, sugar cereals, and unhealthy snacks. In one study obesity rate were lowest in children who watched television one hour or less a day and highest in those who watched four or more hours.
﹡Sugar, particularly from soda, other sweet drinks, and fruit juice, may be major contributors to childhood obesity. One study reported that drinking soda regularly increases a child’s risk for obesity by 60%.
﹡Less physical exercise and greater sitting activities play another significant role in obesity in children. A high level of physical activity – not just using up energy – is important for weight control in young people.
Family History. Parental obesity more than doubles the risk that a young child, whether thin or overweight, will become obese as an adult. In older children and teenagers, obesity in parents starts to affect less as a predictor(预言) for body weight than their own weight. The risk may be due to environmental or genetic factors, or both.
Ethnic and Socioeconomic Factors. As in adult populations, children from lower socioeconomic groups and minority populations are at higher risk for obesity. For example, among young Mexican Americans and African Americans, there has been an increase in overweight trend of about 13% to over 23%.

Skateboarding has become one of several non-traditional activities that PE teachers around America are introducing to inspire kids to exercise regularly. Some PE classes feature in-line（滚轮） skating, yoga, and even rock climbing. Experts have called those types of activities “the new PE”.
Such activities are part of a larger effort to help kids develop lifelong fitness habits and to keep them from becoming overweight. Now, 9 million U.S. children and teens are overweight. Obesity (肥胖) can lead to health problems such as diabetes and heart disease later in life.
"Our children and youth are becoming unhealthy and obese," says Johnson. "Skateboarding is a great activity that keeps kids doing physical movement and gives them new skills and interest."
Some schools don't allow skateboarding because they say it is dangerous. Tim, however, argues that regular practice eliminates a great deal of the danger. "We teach students how to do it and how to do it safely," he says.
Some people say skateboarding teaches life lessons. “Skateboarding teaches kids to believe that if they stick with something they will finally succeed. ”says education expert Richard Savor from College in Portland.
Skateboarding inspires kids not to give up in learning difficult skills. "It's natural for kids to want to learn and get better at things," adds Tim. "When it comes to skateboarding, they'll try a trick hundreds of times before they succeed." That same effort could be made in schoolwork.
Eric Brown agrees that skateboarding requires kids to stop saying a task is too hard for them. "A baby will attempt to walk 600 to 900 times before he or she is successful," says Eric, "We tell students that they shouldn't say 'I can't do it' unless they've tried 600 to 900 times.
72. Skateboarding is introduced into American schools to ______________.
A. encourage students to compete bravely in competition
B. teach students how to deal with risk.
C. prevent students suffering from heart disease later in life.
D. help students form the habit of doing sports
73. The underlined word "eliminates" in Paragraph 4 probably means ______________.
A. reduces. B. increases C. adds D. brings
74. What life lesson do kids learn from skateboarding?
A. To succeed in life you have to learn skateboarding.
B. You will succeed in life if you don't give up.
C. Only after failing 600 to 900 times can you succeed.
D. There is no hard work after learning skateboarding well.
75. What would be the best title for the passage?
A. The dangerous PE B. Skills of skateboarding. C. The new PE. D. The change of PE.

Most people regard zoos as safe places for animals, where struggles such as difficulty finding food and avoiding predators（捕食性动物） don't exist. Without such problems, animals in zoos should live to a ripe old age. But that may not be true for the largest land animals on Earth. Scientists have known that elephants in zoos often develop diseases, joint problems and behavior changes. Sometimes, they even become unable to have babies.
To learn more about how captivity(监禁) affects elephants, a team of international scientists led by Mason, a biologist, compared the life spans of female elephants born in zoos with female elephants living outdoors in the wild. Zoos keep detailed records of all the animals in their care, documenting factors such as birth dates, illnesses, weight and death. These records made it possible for the researchers to analyze 40 years of data on 800 elephants in zoos.
The team found that female elephants born in zoos lived an average of 16.9 years. Their wild counterparts（同类事物） who died of natural causes lived an average of 56 years——more than three times as long.
Scientists don't yet know for sure why wild elephants seem to live so much better than their zoo-raised counterparts. Mason thinks stress and obesity(肥胖) may be to blame. Zoo elephants don't get the same kind of exercise as they do in the wild, and most are very fat. Elephant social lives are also much different in zoos than in the wild, where they live in large groups.
Another finding from the study showed that elephants born in zoos were more likely to die earlier than elephants captured in the wild and brought to zoos. Mason suggests stress in the mothers in zoos might cause them to have babies that are less likely to survive.
The study raises some questions about acquiring more elephants to keep in zoos. While some threatened and endangered species living in zoos reproduce successfully and keep healthy populations, that doesn't appear to be the case with elephants.
【小题1】The text tells us that zoo elephants are different from other zoo animals because they________
| A．develop health problems. |
| B．1ive to a ripe old age. |
| C．are not afraid of predators. |
| D．have difficulty eating food. |

| B．Female zoo elephants die earlier than their wild counterparts. |
| C．Female zoo elephants live longer than their wild counterparts. |
| D．Both elephants in zoos and those in the wild live in large herds. |
| A．Zoo-born elephants should be attended more carefully |
| B．Elephants are no longer an endangered species. |
| C．It may not be a wise policy to keep elephants in the zoo. |

Anyone for kimchi(韩国泡菜)? Around 2,000 women made the traditional dish last week in Seoul,the capital of the Republic of Korea(ROK). 
Kimchi traditionally has a rosy color. Korea.net says: “The color red wards off (避开) evil spirits. The color represents the spirit of the Korean people and kimchi is more than just a food. It’s a culture.”
A meal without kimchi is unthinkable. So what is kimchi?
Joan Raymond, food writer for US website health.com, writes: “It’s a reddish, fermented (发酵的) cabbage dish , made with a mix of garlic salt, vinegar, chili peppers and other spices.
It is served at every meal, either along with or mixed with rice and noodles. It is part of a high-fiber, low fat diet, which has kept obesity(肥胖) at bay.”
Kimchi is used in everything from soups to pancakes and as a topping (配料) on pizza and burgers.
Health.com named kimchi in its list of the world’s top five healthiest foods as it is rich in vitamins, aids digestion and may even reduce the risk of cancer.
A study conducted by Seoul National University claimed that chickens infected with the H5N1 virus (bird flu) recovered after eating food containing the same bacteria found in kimchi.
When Koreans pose for photos, they say “kimchi”, instead of “cheese”.

阅读下面短文，并根据题目要求用英语回答问题（请注意问题后的字数要求）。
Sleepless in Seattle? Hardly. West Virginia is where people are really staying awake, according to the first government study to monitor state-by-state differences in sleeplessness. West Virginians’ lack of sleep was about double the national rate, perhaps a side effect of health problems such as obesity(肥胖), experts said.
Nearly 1 in 5 West Virginians said they did not get a single good night’s sleep in the previous month. The national average was about 1 in 10, according to a federal health survey. Tennessee, Kentucky and Oklahoma also were notably above average with nearly 1 in 7 people reporting in a lack of sleep. In contrast, North Dakota was below average, with only 1 in 13 reporting that degree of sleeplessness. Health officials do not know the exact reasons for the differences.
In the survey, people weren’t required to answer the question why they were not able to get enough rest or sleep. But experts noted several possible explanations: West Virginia ranks at or near the bottom of the nation in several important measurements of health, including obesity, smoking, heart disease and the proportion of adults with disabilities.
Studies have increasingly found that sleeping problems often occurred among people with certain health problems, including obesity. “You would expect to see poorer sleep within a chronically (慢性地) diseased population,” noted Dr Ronald Chervin, a sleep disorders expert in University of Michigan.
Financial stress and work shifts(倒班)can play roles in sleeplessness, too, Chervin added. He suggested those may be contributing factors in West Virginia, an economically depressed state with tens of thousands of people working in coal mining.
The report was based on results of an annual telephone survey of more than 400,000 Americans, including at least 3,900 in each state. The survey did not include people who use only cellphones.
1.What is the main idea of Paragraph 1? (No more than 15 words.)
2.What does the underlined word “notably” in Paragraph 2 mean? (No more than 3 words.)
3.What was the possible reason for the high rate of sleeplessness in West Virginia according to Paragraph 3? (No more than 12 words.)
4.List three factors that contribute to sleeplessness based on the passage.
(No more than 8 words.)
①______________________ ②________________________ ③______________________
5.How was the research carried out? (No more than 10 words.)
