The United States is facing a growing concern: rising obesity(肥胖) rates. A new report says adult obesity rates rose last year in 23 of the 50 states. And, the percentage of obese children was at or above 30% in 30 states. Mississippi had the highest rate of adult obesity in the new study. 32.5% of the state’s adults were obese. Mississippi also had the highest rate of obese and overweight children. 44.4% of all children between the ages of ten and seventeen years were obese or overweight.
The study used a system of measurement called the Body Mass Index(B-M-I) to define words like obese and overweight. To find your B-M-I, divide your weight in kilograms by height in meters squared. A normal B-M-I is between 18.5 and 24.9. The B-M-I of someone overweight is between 25 and 29.5. And, an obese person has a B-M-I above 30.
The new report says widespread obesity is increasing the rates of long-lasting diseases, such as heart disease. Obesity is also responsible for an increasing part of health care costs in the United States. Health care costs have grown while many Americans are getting fatter. A lack of physical exercise, watching TV too much and eating junk food contribute to the rising obesity rate. The report says the current economic recession(经济衰退) could worsen obesity rates by increasing food prices. This would make healthy foods cost more. The report blames the recession for rising rates of depression, anxiety and stress, which are closely linked to obesity in many cases.
The report offers some ideas for dealing with obesity within government health care reforms. They include making sure that every adult and child has a right to preventive medical services. Also, people should do more physical exercise, drive less and eat less junk food to fight obesity.

Scientists studying the impact of climate change on the Arctic need to consider ways to reduce their own carbon footprints(碳排放量), says Ryan Brook, a researcher who regularly flies north to study the health of caribous(驯鹿).He calls on scientists to show leadership by examining and sharing ways to reduce the impact of working in polar regions.
“The importance of the research is not at question here. It is important to our understanding of and adapting to climate change. But we need to think about better approaches,” says Brook.
“This is an issue for all scientists, though polar researchers often travel particularly long distances using commercial air travel. We also rely extensively on small aircraft, icebreakers, and snowmobiles, all of which produce large amounts of carbon.”
Brook studies the health of caribou herds in Nunavut and Northwest Territories. He works with northern wildlife managers. This work typically takes him north five or six times per year and when he calculated his own carbon footprint, he was not happy with the result.
“My research footprints are about the same as the annual footprints of an average Toronto resident. Basically, I have two footprints — my own personal life, which is moderate, and my research footprint.”
Climate scientists can rightly argue that Arctic research is a specialized field and the community of scientists who travel north is relatively small. Even if all scientists working in the north reduced their carbon emissions, it would not make a big impact on the global scale. For Brook, it’s the option that matters.
There are ways researchers can reduce the amount of carbon they use. Some helicopters use less fuel than others. Solar and wind power are alternatives to gas-fired generators. And while carbon offsets(抵消) don’t reduce the amount of carbon emitted, they are an easy first step.
“There aren’t necessarily any easy answers, but we need to start talking about it,” says Brook. “This is particularly important for the next generation of scientists being trained and I hope to see them become leaders in this issue.”

In all one’s lifetime it is oneself that one spends the most time being with or dealing with. But it is exactly oneself that one has the least understanding of.
When you are going upwards in life you tend to overestimate yourself. It seems that everything you seek for is within your reach. When you are going downhill you tend to underestimate yourself, mistaking difficulties for your own incompetence.
To get a thorough understanding of oneself is to gain a correct view of oneself-aware of both one’s strengths and shortages. You may look forward hopefully to the future but be sure not to expect too much, for ideals can never be fully realized. You may be courageous to meet challenges but it should be clear to you where to direct your efforts. That’s to say so long as you have a perfect knowledge of yourself there won’t be difficulties you can’t overcome.
To get a thorough understanding of oneself needs self-appreciation. Whether you think you are a towering tree or a blade of grass, a high mountain or a small stone, you represent a state of nature that has its own value. If you earnestly admire yourself you’ll have a real sense of self-appreciation, which will give you confidence. As soon as you gain full confidence in yourself, you’ll be enabled to fight and overcome any adversity.
To get a thorough understanding of oneself also requires doing oneself a favor when it’s needed. In time of sadness, do yourself a favor by sharing it with your friends so as to change a gloomy mood into a cheerful one; in time of tiredness, do yourself a favor by getting a good sleep. As you are aware, what a person physically has is but a human body that’s vulnerable when exposed to the elements. So if you fall ill, it’s up to you to take a good care of yourself.
In a word, to get a thorough understanding of oneself is to get a full control of one’s life. Then one will find one’s life full of color and flavor.

|
D．it is essential that a person get a thorough understanding of himself |

|
A．your shortages might stop you succeeding |
|
B．ideals can never be turned into realities |
|
C．you are likely to lack enough courage |
|

MIANYANG—At a corner of the city’s Jiuzhou Stadium, one of the biggest camps set up for those left homeless in the earthquake, 62-year-old Liu Yaorong was leaning against a window on Thursday.
Pointing to a quilt and clothes he received from the local government, he said: “These are all I have. My home collapsed in the quake, and everything in the town was flooded.”
He used to live in Xuanping town of Beichuan county which was destroyed by the quake. Adding to his misery, rivers blocked by landslides(山崩) led to flooding in the town.
But Liu said he was lucky because he was healthy, otherwise he would not have the energy to walk 10 hours on damaged and dangerous mountainous roads to escape the flood on Monday. He said the trip used to take him about 90 minutes when the roads were in good condition.
The journey was difficult and “rocks kept falling,” he said, showing injured legs and black, split toenails.
Liu said his three sons were working in eastern cities as migrant workers.
“I’ve been living alone in the mountains for more than 20 years. My wife died 30 years ago,” he said in a low voice.
During his journey to Mianyang, Liu said he saw many elderly people who chose to stay.
“Soldiers were persuading them to leave for fear of floods,” he said.
Talking about his home before the quake struck, Liu’s mood lifted. “I raised pigs and chickens, and grew vegetables. I could have rice, meat and greens almost every day,” he said.
“But now, I have only biscuits and instant noodles.”
Liu said one of his sons returned home from Wenzhou, Zhejiang Province, after the quake, but left because the father refused to go with him.
“I don’t want to leave home. And I know it is difficult for them out there. How could I add to their burden?” he asked, his eyes red.
“I still want to go back to my home. Given a small piece of land, I could live by myself.”
It is learnt that resettlement plans for displaced people have not been finalized.
However, not every elderly person is as strong-willed as Liu.
Psychologists said the elderly need as much comfort as children. Lu Jianguo, a psychologist from Chengdu Medical College, said “We will first let them cry and tell their stories, and then help them regain confidence.”
1.Which of the following is TRUE according to the passage?
|
A．Liu Yaorong spent 8.5 hours more than usual covering the roads in escaping the flood. |
|
B．The flood was followed by an earthquake in Xuanping in the same day. |
|
C．Liu Yaorong was in time to escape the quake without being hurt. |
|
D．Being healthy, Liu Yaorong was the only old man to escape the flood. |
2.The underlined word “ misery ”in the third paragraph most probably means “ ”.
|
A．happiness |
B．fortune |
C．puzzle |
D．suffering |
3.What’s Liu Yaorong’s attitude towards self-relief after the earthquake?
|
A．Positive. |
B．Negative. |
C．Aggressive. |
D．Dependent. |
4. What would be the best title for the news report?
|
A．Elderly react more quickly to flood disaster |
|
B．Elderly try hard to deal with quake disaster |
|
C．Elderly prefer to stay at their own home |
|
D．Elderly are well cared for by government |
