C
Recently the World Health Organization announced that the disease of
smallpox（天花）had almost been wiped out in most parts of the world, thanks to widespread vaccination（种牛痘）. Most people are vaccinated at least once in their lives and if they wish to travel from one country to another they must be able to prove that they have had a recent vaccination. In this way the disease has been prevented from spreading and today one seldom hears of it at all.
This is mainly because of the great discovery made by a village doctor, Edward
Jenner, in about 1798 when he published his report of his new experiment called vaccination (from the word ‘vacca’ meaning a cow). Jenner discovered that people who worked with cattle often suffered from a harmless disease which they caught from the cattle, but these people never seemed to get smallpox. So he experimented by putting the disease into a small opening on the arms of healthy people, and though their arms became painful for a day or two, they soon recovered and none of these people ever got smallpox.
So the news of the wonderful discovery spread to other countries and people
rushed to their doctors to be vaccinated. In many countries the simple way to deal with the arm was done on thousands of people, and the terrible smallpox be

gan to disappear.

Have you ever been in a situation, where you felt uneasy because of something you think you may have forgotten to do or perhaps a feeling that you annoyed someone whom you wanted to get along with really well. If you have experienced such feelings and worse on a regular basis, then you most probably are a victim of anxiety attacks.
All of us, to some extent, have experienced anxiety at different levels. There are somethings you may know about anxiety, and some things that you may not be familiar with. So in order to be prepared for your unexpected feeling of anxiety, you need to get to know what anxiety is before it escalates into a panic attack.
Anxiety is simply the feeling of discomfort, uneasiness or fear of what may eventually happen resulting from an imagined, or a real threatening condition. On the extreme end panic attacks can occur due to heightened(增加) feelings of anxiety.
There are two main symptoms(症状) during an anxiety / panic attack and these are physical and emotional symptoms. Physical symptoms include difficulty in breathing, shaking, direct feeling of heat, rapid heartbeat and tiredness while emotional symptoms deal with worrying, depression, fear, and lack of focus.
In spite of the negative impression we have for anxiety, it is not dangerous in any way whatever. The feeling of anxiety is not bad, in fact it’s more of a defensive feeling which protects us from possible danger by engaging a response within us in fight or fight situations. So it’s not the “bad guy”, you just have to learn how to control it. Panic attacks, however, are far more dangerous and should be a concern to your health. Panic can sometimes result in blurred (模糊不清的) vision, difficulty in breathing due to a tight chest. The best way to different anxiety from any serious illness is to ask a medical expert for advice on a regular basis.

Not all think laughter is the best medicine, but it seems to help．So scientists carried on a new study of diabetes （糖尿病） patients who were given a good dose of humor for a year to prove it．
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．To find out if laughter was good to health．

B．To discover the best medicine to cure diabetes．

C．Because the number of diabetic patients is the largest in the world．

D．Because diabetic patients need more laughter than other patients．

Recently a man came to me, because he was told that there is fluid(积液) around his heart. After trying many drugs which were of no use to reduce the fluid, the doctor told him the only other choice was to have an operation. He refused because he knew that every illness has a mental cause and that if he had the operation but did not clear the mental cause, the fluid would return. At last, he searched the Internet to find a metaphysical healer(玄学治疗师), and he found me.
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．

If you give something to someone for free, will that person value it and use it? Development experts have debated this question for decades. Some think the act of paying causes people to value something and use it more.
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.
小题1: The debate among experts focuses on .

A．a special use of bed nets in Africa

B．the use of assistance-related products

C．the importance of social programs for the poor

D．a popular way to help the poor

小题2: According to some experts, certain health treatments .

A．can only be sold to the rich	B．should be completely free
C．are too expensive	D．are not needed by the poor

小题3:What can be inferred from Paragraph 2?

A．The WHO"s advice may not be always practical.

B．Many Africans don"t know the function of bed nets.

C．The case of Kenya is doubtful.

D．Bed nets given to Africans are poor in quality.

小题4: What may be the possible change in the social program according to the third paragraph?

A．Some of them may become financially independent.

B．Many of them will not be organized by the government.

C．Some of them will go to developed countries.

D．Most of them will be free of charge.
