It is obvious that doctors recognize obesity as a health problem. So why is it so hard for them to talk to their patients about it?

The results of two surveys, one of primary care physicians and the other of patients, found that while most doctors want to help patients lose weight and think it is their responsibility to do so, they often don’t know what to say.

“So while doctors may tell patients they are overweight, the conversation often ends there,” said Christine C. Ferguson, director of the Stop Obesity Alliance. “Patients are not told about the possibility of diabetes (糖尿病),” she said. “And doctors don’t feel they have good information to give. They felt that they didn’t have adequate tools to address this problem.

The lack of dialogue hurts patients, too. The patient survey, of over 1,000 adults, found that most overweight patients don’t even know that they’re too heavy. Only 39 percent of overweight people surveyed had ever been told by a health care provider that they were overweight.

Of those who were told they were obese, 90 percent were also told by their doctors to lose weight, the survey found. In fact most have tried to lose weight and may have been successful in the past—and many are still trying, the survey found. And many understand that losing even a small amount of weight can have a positive impact on their health and reduce their risk of obesity­related diseases like hypertension and diabetes.

Dr. William Bestermann Jr., medical director of Holston Medical Group, in Kingsport, Tenn. , which ranks the 10th in obesity among metropolitan areas in the United States, said the dialogue had to be an ongoing one and could not be dropped after just one mention of the problem. “If you’re to be successful with helping your patients lose weight, you have to talk to them at actually every visit about their progress, and find something to encourage them and coach them,” he said.

He acknowledged that many doctors tend to be not optimistic.

“Part of this is that there's this common belief, and doctors are burdened by it, too, that overweight people are weak-willed and just don’t have any willpower and are self­indulgent and all that business,” he said. “If you think that way, you’re not going to spend time having a productive conversation.”

1.What is the Stop Obesity Alliance most probably in Paragraph 3?

A. An organization of doctors suffering from obesity.

A. About 350.                           B. About 390.

C. About 900.                           D. About 1,000.

3.What can be inferred about obesity patients in Paragraph 5?

A. They are not as hopeless as doctors think they are.

B. Most of them have tried hard to lose weight, but in vain.

C. Without their doctors’ constant coaching, there is little chance of their succeeding in losing weight.

D. Most of them have just given up their hope of becoming less heavy.

4.  According to the passage, which factor contributes to the lack of dialogue between doctors and patients?

A. Most doctors never think of warning their patients about their weight problem.

B. Many doctors find it difficult to persuade overweight people to lose weight.

It is a mystery that has puzzled doctors for decades. But experts believe they have now finally solved the tricky question of why winter is notoriously known as the flu season.

According to a new research, the influenza virus coats itself in a protective fatty shield that is tough enough to resist cold temperatures. The butter-like material only melts when it hits the respiratory tract（呼吸道）, leaving the virus free to infect cells-- a process scientists say is like an M&M melting in the mouth.

However, in warmer outdoor temperatures, the protective coating melts before it reaches a person or an animal, killing the bacteria before they can infect someone. Joshua Zimmerberg, from the National Institute of Child Health and Human Development (NICHD), in the US, which led the study, said: “Like an M&M in your mouth, the protective covering melts when it enters the respiratory tract. It's only in this liquid period that the virus is able to enter a cell to infect it.”

In the past, scientists worked on theories that flu is more common in winter because people spend more time inside or the radiation from the sun in summer kills off germs. But no research successfully explained the spread of the disease.

Researchers have already claimed that the report, which is published in the journal Nature Chemical Biology, could lead to new ways to prevent and treat flu. “Now that we understand how the flu virus protects itself so that it can spread from person to person, we can work on ways to prevent it.”

Influenza and other respiratory viruses are spread in small drops broadcast by coughing, sneezing and talking and which can also settle onto surfaces, to be picked up on fingertips.

1. What can be the best title of the passage?

A. The mystery that has puzzled doctors for decades.    B. New ways to prevent and treat flu.

2. Which of the following statements is NOT true?

A. Doctors have been trying hard to discover why flu strikes in winter.

B. In the past, scientists didn’t know how flu spreads.

C. It is possible that flu virus will no longer threaten humans in winter.

D. People get affected by flu because they spend much more time inside in winter.

3. Where should you insert the following paragraph into the passage?

Duane Alexander, the director of NICHD, said: “The study results open new avenues of research for thwarting (使…受挫)winter flu outbreaks.”

A. Between Paragraphs 1 and 2.     B. Between Paragraphs 3 and 4.

C. Between Paragraphs 4 and 5.     D. Between the last two paragraphs.

4.In what process or order does flu occur?

a. The virus infects cells                 b. The influenza virus was born

c. The butter-like material melts           d. The virus hits respiratory tract

e. The virus coats itself in butter-like shield  f. The virus is free
