New research shows that overweight or even mildly obese people have a lower risk of early death than people considered to be normal weight.

Researchers examined the results of 97 studies. Most of the studies were less than 10 years old. They included almost three million adults from around the world, including the United States, Canada, China, Taiwan, Brazil, India and Mexico.

The researchers at the National Center for Health Statistics found that people who are considered overweight or slightly obese were five to six percent less likely to die from all causes than people of normal weight. People with higher obesity ratings, however, had almost a 30 percent greater risk of death compared to normal-weight individuals.

Katherine Flegal was the lead author of the study. She says she was not surprised that overweight people would not have a higher risk of death.

“Because we’d actually already read a lot of this literature and realized it was likely that mortality rates (死亡率) for overweight would be at least not higher than normal weight. I guess I was a little bit surprised that it was definitely lower. And I was also surprised that the lower rates of obesity also didn’t seem to differ from normal weight.”

But she says the difference in death rates appears to be small between normal-weight people and those who are overweight or mildly obese.

The study has raised new questions about “body mass index,”(体重指数) or BMI. This is a measurement of body fat as a ratio(比率) of height to weight. In recent years, many public health experts have promoted body mass index as a way to predict the risk of health problems. Bu t a person's BMI can be misleading in some cases.

Steven Heymsfield ,the executive director of the Pennington Biomedical Research Center, says people can be physically fit and in good health, but might weigh more because they are more muscular.

Still, Dr. Heymsfield says people should not think gaining extra weight is OK just because of the new findings. He says being at a healthy weight lowers the risk for heart disease and diabetes(糖尿病).

1.According to the new findings, the researchers found that __________ .

A.People with high obesity have a lower risk of early death than people with low obesity

B.People with overweight have a greater risk of early death than people of normal weight.

C.People with mild obesity are less likely to die than people of normal weight.

2.What does the underlined word “literature” in paragraph 6 mean ?

A. BMI is commonly used to measure body fat as a ratio of height to weight.

B. Not all people with a little higher BMI are fat .

C. Many public health experts encourage more people to use BMI as a way to predict the risk of health problem

     In a moment of personal crisis, how much help can you expect from a Ne York taxi driver? I began
studying this question and found the answers interesting.
     One morning I got into three different taxis and announced, "Well, it's my first day back in New York
in seven years. I've been in prison." Not a single driver replied, so I tried again. "Yeah, I shot a man in Reno."
I explained, hoping the driver would ask me why, but nobody asked. The only response came from a Ghanaian
driver, "Reno? That is in Nevada?"
     Taxi drivers were uniformly sympathetic when I said I'd just been fired. "This is America," a Haitian driver
said."One door is closed. Another is open." He argued against my plan to burn down my boss's house. A
Pakistani driver even turned down a chance to profit from my loss of hope; he refused to take me to the middle
of George Washington Bridge-a $ 20 trip. "Why you want to go there? Go home and relax. Don't worry. Take
a new job."
     One very hot weekday in July, while wearing a red ski mask and holding a stuffed pillowcase with the word
"BANK" on it, I tried calling a taxi five times outside different banks. The driver picked me up every time. My
ride with a Haitian driver was typical of the superb assistance I received.
     "Let's go across the park." I said. "I just robbed the bank there. I got $ 25 000."
     "$ 25 0007" He asked.
     "Yeah, you think it was wrong to take it?"
     "No, man. I work 8 hours and I don't make almost $ 70. If I can do that, I do it too."
     As we approached 86th and Lexington, I pointed to the Chemical Bank.
     "Hey, there's another bank," I said, "Could you wait here a minute while I go inside?"
     "No, I can't wait. Pay me now." His reluctance may have something to do with money-taxi drivers think
the rate for waiting time is too low-but I think he wanted me to learn that even a bank robber can't expect
unconditional support.
1. From the Ghanaian driver's response, we can infer that _____.
A. he was indifferent to the killing
B. he was afraid of the author
C. he looked down upon the author
D. he thought the author was crazy
2. Why did the Pakistani driver refuse to take the author to the middle of the George Washington Bridge?
A. Because he was able to help the author to find a new job.
B. Because he wanted to go home and relax.
C. Because it was far away from his home.
D. Because he thought that the author would commit suicide.
3. What is the author's interpretation of the driver's reluctance "to wait outside the Chemical bank"?
A. The driver thought that the rate for waiting time was too low.
B. The driver thought it wrong to support a taxi rider unconditionally.
C. The driver was frightened and wanted to leave him as soon as possible.
D. The driver did not want to help a suspect to escape from a bank robbery.
4. Which of the following statements is true about New York taxi drivers?
A. They are ready to help you do whatever you want to.
B. They often refuse to pick up those who would kill themselves.
C. They are sympathetic with those who are out of work.
D. They work only for money.
5. The passage mainly discusses _____.
A. how to please taxi drivers
B. how to deal with taxi drivers
C. the attitudes of taxi drivers towards riders in personal trouble
D. the attitudes of taxi drivers towards troublesome taxi riders
