2、se the best answer from the four choices marked A), B), C) and D ). For questions 8-10, complete the sentences with the information given in the passage.Health Care and EpidemicsEveryone suffers from disease at some time or another. However, millions of people around the world do not have good healt

3、h care. Sometimes they have no money to pay for medical treatment. Sometimes, they have money, but there is no doctor. Sometimes the doctor doesnt know how to treat the disease, and sometimes there is no treatment. Some people are afraid of doctors. When these conditions are present in large populat

4、ion centers, epidemic can start.Epidemics can change history. Explorations and wars cause different groups of people to come into contact with each other. They carry strange diseases to each other. For example, when Europeans first came to North and South America, they brought diseases with them tha

5、t killed about 95% of the native American population.People are afraid of unknown things, especially diseases. People have all kinds of ideas about how to prevent and treat disease. Some people think that if you eat lots of onions or garlic, you wont get sick. Others say you should take huge amounts

6、 of vitamins. Scientific experiments have not proved most of these theories. However, people still spend millions of dollars on vitamins and other probably useless treatments or preventatives. Some people want antibiotics (抗生素) whenever they get sick. Some antibiotics are very expensive. Much of thi

7、s money is wasted because some diseases are caused by a virus. Viruses are even smaller than bacteria, and they cause different kinds of diseases. Antibiotics are useless against viruses.Because of their fear, people can be cruel to victims of disease. Sometimes they fire them from their jobs, throw

8、 them out of their apartments, and refuse them transportation services. In the plague (瘟疫) epidemics a few hundred years ago, people simply covered the doors and windows of the victims houses and left them to die inside, all in an effort to protect themselves from getting sick.Doctors know how most

9、epidemic diseases spread. Some, like tuberculosis, are spread when peoples sneeze sends the bacteria shooting out into the air. Then they enter the mouth or nose of anyone nearby.Others are spread through human contact, such as on the hands. When you are sick and blow your nose, you get viruses or b

10、acteria on your hands. Then you touch another persons hand, and when that person touches his or her mouth, nose, or eyes, the disease enters the body. Some diseases spread when people touch the same dishes, towels, and furniture. You can pick up a disease when you touch things in public buildings.Ot

11、her diseases are spread through insects such as flies, mosquitoes.One disease that causes frequent, worldwide epidemics is influenza, or flu for short. The symptoms of influenza include headache and sometimes a runny nose. Some victims get sick to their stomachs. These symptoms are similar to sympto

12、ms of other milder diseases. Influenza can be a much more serious disease, especially for pregnant women, people over sixty-five, and people already suffering from another disease, such as heart problems. About half of all flu patients have a high body temperature, called a fever. Flu is very infect

13、ious. One person catches the flue from another person; it doesnt begin inside the body as heart disease does.Sometimes medicine can relieve the symptoms. That is, it can make a person cough less, make headaches less intense, and stop noses from running for a while. However, medicine cant always cure

14、 the disease. So far, there is no cure for many diseases and no medicine to prevent them. People have to try to prevent them in other ways.Some disease can be prevented by vaccination (接种疫苗). A liquid vaccination is injected into the arm or taken by mouth and the person is safe from catching that di

15、sease. Other diseases can be prevented by good health habits, such as drinking only clean water, and washing the hands often.Epidemics usually start in areas of large population. Poor people in big cities who live crowded together in miserable conditions have the most health problems. They often hav

16、e the least education about disease prevention. For example, it is difficult for a person who has no electricity to refrigerate food or boil drinking water. With no money, the person cant even buy soap to wash his or her hands.Disease prevention costs much less than disease treatment. It seems compl

17、etely illogical, but some countries like the United States spend much more health-care money on treatment for diseases than on programs to prevent disease in the first place. Most doctors and other hospital workers stay in their institutions. Only a few doctors go out into the streets of the poor ar

18、eas to educate the people. Only a few doctors and some nurses vaccinate people and supervise them to make sure they take their medicine. Most people who “help the poor people with their health problems are volunteers.How can you use all this information for your own good health? When someone you kno

19、w becomes ill, try to avoid physical contact with that person. If you get sick yourself, keep your towel and dishes separate from everyone elses. Try not to touch things that belong to others. Dont touch other people, and dont shake hands. Explain why, however-you dont want people to think you are i

20、mpolite. Wash your hands often if you are ill or anyone around you is ill.Researchers continue searching for a way to cure or prevent epidemic diseases. Meanwhile, it is worth the money for governments to provide preventative health care for all of their people. Preventing epidemics is much cheaper
