Researchers divide 20 high-risk diabetic patients into two groups．Both groups were given standard diabetes medicine．Group L viewed 30 minutes of humor of their choice, while Group C, the control group, did not．This went on for a year of treatments．
By two months into the study, the patients in the laughter group had lower level of the hormones epinephrine （肾上腺素）, considered to cause stress, which is known to be deadly．After the 12 months, HDL cholesterol rises 26 percent in Group L but only 3 percent in Group C．In another measure, C-reactive proteins, a maker of heart disease, drop 66 percent in the laughter group but only 26 percent in the control group．
“The best doctors believe that there is a physical good brought about by the positive emotion, happy laughter,” said study leader Lee Berk of Loma Linda University．And other research has found that humor makes us more hopeful．Still, more study is needed, Berk said．The research by Berk found that humor can bring about similar changes in body chemistry, which was proved in the new study．The research result will be presented this month at the meeting in the US．Research at the University of Maryland School of Medicine shows that laughter causes the inner lining of blood vessels to expand, increasing blood flow in a way thought to be healthy．
“Lifestyle choices have an important effect on health and these are choices which we and patients should pay attention to, rather than prevention and treatment,” Berk said in a statement this week．
小题1:Why did the scientists carry on the new research?

| A．C-reactive proteins increase 66 percent in Group C |
| B．the level of the hormones epinephrine stays the same in both groups |
| C．the level of the hormones epinephrine has dropped |
| D．C-reactive proteins reduced 66 percent in Group L |
| A．something bad to our health | B．something good to our health |

The mental cause of his disease was an experience of breaking up five years ago with several friends, whom he had known for over twenty years. This experience broke his heart. Not knowing how to “mend” his broken heart, his body created a “repair” by surrounding his heart with fluid to protect it from the sad feelings.
Our work focused on reminding him of the feelings of being loved and forgiving his friends. Months later, his hearts was mended and the fluid disappeared. He left my office after the final session with a smile on his face and a spring in his step.
The key is: to create a healthy body, you must be healthy not only in body, but also in mind.
To be mentally healthy, you need to build up strong relationships. Creating strong relationships will insure that you are accompanied by a network of loving persons. It is important for building a support system that lifts your spirits. Even when you are alone, you will not feel lonely or upset. Strong relationships are not spaceships——they are not hard to build.
小题1:In order to cure his illness, which of the following ways did the patient try?
taking many medicines having an operation
seeing a metaphysical healer visiting different doctors
| A． | B． | C． | D． |
| A．a mentally healthy body | B．a repaired heart |
| C．a network of loving persons | D．a support system |
| A．Loving others will keep you in good spirits. |
| B．Heart illness can be cured without operation. |
| C．Creating strong relationships will keep you healthy. |
| D．Spiritual health is necessary for physical health. |
| A．Old friendship is easy to lose. | B．A good friendship is a useful medicine |
| C．The best doctor is your own body | D．It needs many efforts to build relationships |
| A．How to build strong relationships | B．How to protect your heart |
| C．How to keep healthy mentally | D．How to live a healthy life |
Selling necessary health treatments, others argue, may deny them to the people who need them the most.
Consider, for example, chemically treated bed nets, which kill mosquitoes anti protect people against malaria(疟疾)while they are sleeping. William Easterly, an economist at New York University, believes this is one example of development having gone wrong. In a recent book, Professor Easterly suggests bed nets given free in Africa are often used for the wrong purpose. Yet, the World Health Organization (WHO) recommends bed nets be given out free and used by whole communities. The success of a large free bed net campaign in Kenya led the WHO to announce this recommendation
This debate will likely influence social programs in the developing world. Many non-governmental organizations support the creation of self-supporting programs in poor countries. Goods and services are sold for a price to help these programs survive.
According to Rachel Glenerster, who runs a research lab doing development and poverty studies at the Massachusetts Institute of Technology, her several studies have proven that small price changes have a big influence on the number of people who use a product. A price change will reduce the total amount of use of the product as well, she says. She has also found no evidence that the very act of paying for something changes how people use it.
As for a particular product among special populations, some development experts argue that pricing is useful. When it comes to bed nets, Miss Glenerster says research shows no evidence of this. People are just as likely to use a bed net whether they paid for it or not.

| D．Most of them will be free of charge. |

less likely to gain weight than nondrinkers and are at lower risk for obesity (fatness).The findings, reported this week in the Archives of Internal Medicine, are based on a study of 19,220 United States women aged 30 to 40 who fall into the “normal weight” based on their body mass index. Researchers at Brigham and Women’s Hospital in Boston tracked the women’s drinking habits over 13 years. About 60 percent of the women were light or regular drinkers, while about 40 percent reported drinking no alcohol.
Over the course of the study, 41 percent of the women became overweight. Although alcohol is packed with calories, the nondrinkers in the study actually gained more weight over time: nine pounds, on average, compared with an average gain of about three pounds among regular moderate drinkers. The risk of becoming overweight was almost 30 percent lower for women who consumed one or two alcohol drinks a day, compared with nondrinkers.
The findings are certain to be confusing for women who continue to receive conflicting messages about the health benefits and risks of alcohol. Although moderate drinking is associated with better heart health, regular drinking also increases breast cancer risk.
The trend toward les
s weight gain among drinkers doesn’t appear to hold true for men. A 2003 study of Briti
sh men showed that regular drinkers gained more weight than nondrinkers. Studies suggest that drinking alcohol has different effects on eating habits among men and women. Men typically add alcohol to their daily caloric intake, whereas women are more likely to substitute（替代）alcohol for food. In addition, there may be differences in how men and women metabolize（代谢）alcohol. Metabolic studies show that after men drink alcohol, they experience little if any metabolic change. But alcohol appears to slightly speed up a woman’s metabolism.The findings don’t mean women should rush to drink alcohol to lose weight. Other research shows that once a person is already overweight, her alcohol metabolism is more efficient, and so an overweight woman may gain more weight from alcohol than a lean(瘦的) woman. The data do, however, suggest that for many women facing weight problems, the extra calories are probably not coming from alcoholic drinks.
小题1: According to the study, which of the following regular drinker is less likely to gain weight than nondrinkers?
A B C D
小题2:That men regular drinkers gained more weight than women regular drinkers is due to the following except ______.
| A．women are more likely to substitute alcohol for food. |

| C．men and women metabolize alcohol differently. |
| D．men have different effects on eating habits with women. |
| A．so | B．in order that | C．but | D．and then |
| A．Rush to drink alcohol to lose weight |
| B．Add alcohol to his or her daily caloric intake. |
| C．Face the weight problems alone. |
| D．Try to stop drinking any alcohol or wine. |
