The human body has developed its millions of nerves to be highly aware of what goes on both inside and outside of it. This helps us aajust to the outside world. Without our nerves and our brain, which is a system of nerves, we couldn’t know what’s happening. But we pay for our sensitivity. We can feel pain when the slightest thing is wrong with any part of our body. The history of torture is based on the human body being open to pain. But there is a way to handle pain. Look at the Indian fakir (苦行僧) who sits on a bed of nails. Fakirs can put a needle right through an arm, and feel no pain. This ability that some humans have developed to handle pain should give us ideas about how the mind can deal with pain. The big thing in withstanding pain is our attitude toward it. If the dentist says, “This will hurts a little,” it helps us to accept the pain. By staying relaxed, and by treating the pain as an interesting sensation, we can handle the pain without falling apart. After all, although pain is an unpleasant sensation, it is still a sensafion, and sensations are the stuff of life.

A moment's drilling by the dentist may make us nervous and upset. Many of us cannot stand pain.To avoid the pain of a drilling that may last perhaps a minute or two, we demand the "needle"— a shot of novocaine (奴佛卡因) -that deadens the nerves around the tooth.Now it' s true that the human body has developed its millions of nerves to be highly aware of what goes on both inside and outside of it. This helps us adjust to the world. Without our nerves—and our brain, which is a bundle of nerves— we wouldn't know what's happening. But we pay for our sensitivity. We can feel pain when the slightest thing is wrong with any part of our body. The history of torture is based on the human body being open to pain.But there is a way to handle pain.

共用题干第一篇Heat and HealthExtremely hot weather is common in many parts of the world.Although hot weather just makes most people hot,it can cause medical problems and death.Health experts say that since the year 1900,extremely hot weather has killed more people in the United States than any other natural event.One year一the unusually hot summer of 1980一heat caused about 1,700 deaths in the United States.In 1995,more than 600 people died in a similar heat wave in one city一Chicago.To measure extreme heat,government weather experts have developed the Mean Heat Index.It measures the average of how hot it is felt all day on an extremely hot day.Experts say it is the total heat of a hot day or several hot days that can affect health.Several hot days are considered a heat wave.Experts say heat waves often become deadly when the nighttime temperature does not drop much from the highest daytime temperature.The most common medical problem caused by hot weather is heat stress.It is also least severe.For most people,the only result of heat stress is muscle pain.The pain is a warning that the body is becoming too hot. Doctors say drinking water will help the pain disappear after the body again has the right amounts of water and salt.For some people, however,the result is much more serious.For example,doctors say some people face a greatly increased danger from heat stress.These people have a weak or damaged heart,high blood pressure,or other problems of the blood system.Severe heat can help cause a heart attack or stroke.Health experts say this is the most common cause of death linked to hot weather. A heat wave is a period of time during whichA:the weather is much better than usual.B:the nights are much longer than usual.C:the weather is much hotter than usual.D:the days are much longer than usual.
共用题干Stomach UlcerStomach ulcers are the cause of severe pain for many people.Doctors have been able to help lessen the pain of ulcers.They could not cure them.Now doctors have discovered a cause of ulcers.This means they may have found a way to cure people who suffer from the stomach pain.Studies show that ten percent of the population will develop an ulcer at some time in their life.So a possible cure is good news for many people.Ulcers are wounds in the stomach that are similar to small cuts or tears.These wounds can harm the tissue in the stomach,the pipe that carries the food to the stomach or parts of the small intestines.Fluids in the stomach then increase the pain of an ulcer.How does a person know he or she has an ulcer?Doctors say most people with ulcers feel a burning pain in their chest or stomach.This pain often is called heart burn.It usually happens before eating or during the night.It causes some people to lose their desire to eat,or they are unable to keep food in their stomachs.Doctors believed that ulcers were caused by unusually strong stomach fluids,which damaged stomach tissue.Now they have discovered that most ulcers are caused by a bacterial organism called Hillico Bactor Pilorie or H.Pillorie.H.Pillorie bacteria are what make stomach produce extra stomach fluid.Doctors found that they can kill the bacteria with medicines called antibiotics.Health experts say the discovery of a cure for ulcers can save thousands of millions of dollars in medical costs.They also believe curing ui- cers will reduce the number of people who develop stomach cancer.The number of people with stomach cancer is very high in Japan,Southeast Asia and parts of Africa.Doctors say a person is more likely to get an ulcer if his or her family has had one.In fact a person with the family history of ulcers is three times more likely to get one than other peo-ple.There are ways people can protect themselves from developing an ulcer.Doctors say it is more important to reduce the amount of strong fluids in the stomach.To do this,doctors say,people should not smoke cigarettes or drink alcohol.And they say people should reduce tension in their lives.Stomach ulcer can lead to stomach cancer.A:RightB:WrongC:Not mentioned
