You should write at least 120 words following the outline given below in Chinese: 1. 你认为在英语学习过程中存在的主要问题是什么？ 2. 导致这些问题的原因有哪些？ 3. 对于解决这

2、些问题，你有何建议？ （分数：30.00）_二、Reading Comprehensio(总题数：1，分数：71.00)Health Care and Epidemics (流行病) Everyone suffers from disease at some time or another. However, millions of people around the world do not have good health care. Sometimes they have no money to pay for medical treatment. Sometimes they have

3、 money, but there is no doctor. Sometimes the doctor does not 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 population centers, epidemics can start. Epidemics can change history. Explorations and wars

4、 cause different groups of people to come into contact with other. They carry strange disease to each other. For example, when the Europeans first came to North and South America, they brought diseases with them that killed about 95 percent of the Native American population. People are very afraid o

5、f 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 won t get sick. Others say you should take huge amounts of vitamins. Scientific experiments have not proved most of these theo

6、ries. However, people still spend millions of dollars on vitamins and other probably useless treatments or preventatives. Some people want antibiotics whenever they get sick. Some antibiotics are very expensive. Much of this money is wasted because some diseases are caused by a virus. Viruses are ev

7、en 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 them out of their apartments, and refuse them transportation services. In t

8、he plague (瘟疫) epidemics a few hundred years ago, people simply covered the doors and windows of the victim s houses and left them to die inside, all in an effort to protect themselves from getting sick. Doctors know how most epidemic diseases spread. Some, like tuberculosis, are spread when people

9、s sneeze (喷嚏) 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 bacteria on your hands. Then you touch another person s hand, and wh

10、en 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. Other diseases are spread through insects such as flies, mosquitoes

11、, and ticks. One disease that causes frequent, worldwide epidemics is influenza, or flu for short. The symptoms (症状) of influenza include headache and sometimes a runny nose. Some victims get sick to their stomachs. These symptoms are similar to symptoms of other, milder diseases. Influenza can be a

12、 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 contagious. One person catches the flu from another p

13、erson; 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 can t always cure the disease. So far, there is no cure for man

14、y diseases and no medicine to prevent them. People have to try to prevent them in other ways. Some diseases can be prevented by vaccination (接种疫苗). A liquid vaccine is injected into the arm or taken by mouth and the person is safe from catching that disease. Other diseases can be prevented by good h

15、ealth habits, such as drinking only clean water, boiling water that might carry disease, 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 have the l

16、east 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 can t even buy soap to wash his or her hands. Disease prevention costs much less than disease treatment. It seems completely

17、 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 areas t

18、o 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 know bec

19、omes ill, try to avoid physical contact with that person. If you get sick yourself, keep your towel and dishes separate from everyone else s. Try not to touch things that belong to others. Don t touch other people, and don t shake hands. Explain why, however-you dont want people to think you are imp

20、olite. Wash your hands often if you are ill or if 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 cheape

B is for being extremely busy. C is for the conscientious (勤勤恳恳的) way you do your job.

41、 You may be all these things at the office, and more. But when it comes to getting ahead, experts say, the ABCs of business should include a P, for politics, as in office politics. Dale Carnegie suggested as much more than 50 years ago: Hard work alone doesnt ensure career advancement. You have to b

42、e able to sell yourself and your ideas, both publicly and behind the scenes. Yet, despite the obvious rewards of engaging in office politics - a better job, a raise, praise - many people are still unable - or unwilling - to “play the game.“ “People assume that office politics involves some manipulat

43、ive (工于心计的) behavior,“ says Deborah Comer, an assistant professor of management at Hofstra University. “ But politics derives from the word “polite“. It can mean lobbying and forming associations. It can mean being kind and helpful, or even trying to please your superior, and then expecting somethin

44、g in return.“ In fact, today, experts define office politics as proper behavior used to pursue ones own self-interest in the workplace. In many cases, this involves some form of socializing within the office environment - not just in large companies, but in small workplaces as well. “The first thing

45、 people are usually judged on is their ability to perform well on a consistent basis,“ says Neil P. Lewis, a management psychologist. “But if two or three candidates are up for a promotion, each of whom has reasonably similar ability, a manager is going to promote the person he or she likes best. It

46、s simple human nature.“ Yet, psychologists say, many employees and employers have trouble with the concept of politics in the office. Some people, they say, have an idealistic vision of work and what it takes to succeed. Still others associate politics with flattery (奉承), fearful that, if they speak

47、 up for themselves, they may appear to be flattering their boss for favors. Experts suggest altering this negative picture by recognizing the need for some self-promotion. （分数：177.50）(1).“Office politics ( Line 2, Para. 4) is used in the passage to refer to _.（分数：35.50）A.the code of behavior for com
