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%.
69.What’s the main idea of the passage? ______________.
A. The trend of obesity                B. Causes of obesity
C. Fight against obesity                D. Obesity in children
70.How many main factors leading to obesity in children are mentioned?
A. 2              B. 3                C. 4                 D. 5
71.According to the passage, which of the following children is most likely to be obese?
A. A 5-year-old child whose parents are overweight.
B. A 16-year-old teenager whose parents are obese.
C. A child who watches TV one hour per day.

Ship tourism to Antarctica is on the rise: More than 35,000 tourists are expected to visit Antarctic this summer. In 1992-1993, 6,750 visited Antarctica, according to the Antarctica Treaty. All of this tourism, however, is putting both tourists and the environment in great danger.
Among the tourist ships that visit the continent, the Explorer, a Canadian ship, was one of the first. Put to use in 1969, it was built to carry tourists to Antarctica. Last week, however, it became the first commercial passenger ship to sink beneath the waters. Fortunately, all of the passengers and crew members were rescued from the ship. However, the sunken ship endangered the Antarctic’s fragile(脆弱的) environment. The ship was estimated to be holding 48,000 gallons of fuel.
The accident was not unexpected. Both the US and UK had warned a conference of the Antarctic Treaty member countries in May that the tourism situation in this area was a potential disaster. The US said in a paper, people “should take a hard look at tourism issues now, especially those related to ship safety.” Although the Antarctic seas are relatively(相对地) calm, floating ice causes a potential threat to ships. The owner of the Explorer blamed the sinking on a fist-like hole in the ship created by ice.
Many of the other large ships now visiting Antarctica are not designed especially against thick ice. Such ships generally can only come to the continent in summer. But the tourist rush is pushing ships into dangerous situations. “The increasing number of ships operating in Antarctic means that the ship are under great pressure to get there in time for the key visiting sites,” the British government wrote in a paper at the meeting of member countries.
As a natural frontier, Antarctica is in a messy legal situation. There are no obvious answers as to who is responsible for dealing with the threat that tourist may cause to human life and the environment.
There is no coast guard for Antarctica. Do we want it to become Disneyland, or do we need some controls?
76. Which of the following is true according to this passage?
A. Antarctica tourism has a history of about 17 years
B. The number of tourists to the Antarctic is over 5 times as large as that of 17 years ago.
C. The tourism boom has caused holes in the floating ice in the Antarctic.
D. The Antarctica Treaty is responsible for the problem.
77. The sinking of the Explorer____________.
A. led to a conference about the tourism situation in the Antarctic.
B. was caused by the rough seas
C. had been predicted
D. did harm to the Antarctic.
78. It can be inferred from the passage that_________.
A. a Disneyland will be built in the Antarctic
B. fewer people are visiting the Antarctic because of the warnings given
C. not all the ships are suitable to go to the Antarctic
D. some ships take risks visiting the Antarctic in other seasons rather than in summer
79. In this passage, the writer suggests that___________.
A. people had better not make a tour of the Antarctic
B. ships to the Antarctic should be built strong enough
C. there should be legal controls over tourism in the Antarctic
D. the Antarctic’s environment is fragile
80. What attitude does the writer hold towards Antarctic tourism?
A. Supportive. B. Positive. C. Indifferent. D. Anxious.

Several southwestern provinces in China are now experiencing the worst drought(旱灾) since the 1950s. The drought has left 18 million people and 11 million farm animals in Yunnan, Guangxi, Sichuan and Chongqing without enough water supplies. And it has affected 5 million hectares of crops in the provinces.

On an afternoon several years ago, my brother-in-law opened the bottom drawer of my sister’s dress and picked out a beautiful skirt. “ Jan bought this the first time we went to New York, at least 8 or 9 years ago. She never wore it. She was saving it for a special occasion.” he said．I guess this was the occasion: it was the funeral of my sister, after her unexpected death.
He took the shirt and put it on bed, with the other clothes we were taking to the funeral. Then he closed the drawer and turned to me, “Don’t ever save anything for a special occasion. Every day you’re alive is a special occasion.”
I’m thinking about his words, and they’ve changed the way I live my life. I’m spending more time with my family and friends and less time in committee meetings.

Ever since that day, I have been trying very hard not to put off, hold back or save anything that would add laughter and color to our lives.

Baths and bathing have been considered of an important medical therapy to man. In Greece there are the ruins of a bath tub and water system built over 3 000 years ago. The Romans had warm public baths. In some public baths as many 3 000 persons could bathe at the same time.
Treating diseases by bathing has been popular for centuries. Modern medical bathing, or hydrotherapy, first became popular in Europe and by the late 1 700’s also became popular in the United States.
For many years frequent bathing was believed to be bad for one’s health. Ordinary bathing just to be clean was avoided, and perfume(香水) was used to cover up body and smell.
By the 1 700’s doctors began to say that soap and water were good for health. They believed that it was good for people to be clean. Slowly, people began to bathe more frequently.
In the United States ordinary bathing was slow to become popular. During the 18th and early 19th centuries, many Americans were known as “the great unwashed”. In one American city, for example, a person could only take a bath every 30 days! That was a law.
Frequency of bathing today is partly a matter of habit. People know that bathing for cleanliness is important to health. Doctors know that dirty bodies increase that chance of disease.
Therefore in the United States people generally bathe often.

A．A bathing tub.            B．Medical bathing.
