Reading Comprehension (Multiple Choice) (每小题:1 分)
Directions: Read the following passages carefully and choose the best answer from the four choices marked A, B, C and D. Questions 1 to 5 are based on the following passage or dialog. The AIDS virus is carried in a person's body fluids . The virus can be passed during sex with an infected partner or by sharing instruments used to take intravenous (静脉注射 的) drugs. It can also be passed in blood or fluids made from blood or from a pregnant (怀孕 的) woman with AIDS to her developing baby. Many stories about the spread of AIDS are false. You cannot get A IDS from working or attending school with someone who has the disease. You cannot get it from drinking glasses or other objects used by such persons. Officials say no one has caught AIDS by living with, caring for, or touching an AIDS patient. There are several warning signs of being infected with AIDS. They include always feeling tired, unexplained (无 法解释的) weight loss, and uncontrolled expulsion (排 泄) of body wastes. Other warning signs are the appearance of white areas on the mouth, dark red areas of skin tha t do not go away, and a higher than normal body temperature. However, just because you have one or more of these conditions does not mean you have AIDS. Always go to a d octor or health center for a complete examination. The doctor may give you an AIDS blood test. When a virus ent ers the body, the body's defenses against disease produce antibodies (抗 体) to fight the virus. The test shows if the body has produced antibodies to the AIDS virus. Results of the test are known after a few hours. The test tells only if your body has produced AIDS antibodies. It cannot tell if you have AIDS or if you will ever get the disease. In December (1988), the United States government approved (批 准) a simpler and faster AIDS blood test. The newer test can confirm (证实) the presence (出 现) of the AIDS antibodies in about five minutes. 1. The AIDS virus can spread ___________. A. only from a man to woman B. among those who share drug instruments C. by shaking hands with someone who has the virus D. by touching an AIDS patient 2. It is wrongly thought that ___________. A. the AIDS virus can be passed during sex B. the AIDS virus can spread from an expecting mother to her baby C. the AIDS virus can be passed by touching infected blood D. one can get AIDS by working or attending school with someone who has the disease 3. The warning signs of being infected with AIDS do not include ____________. A. weight loss B. uncontrolled expulsion of body wastes C. the appearance of red areas of skin D. a body temperature lower than a normal one 4. If a person is worried that he might have AIDS, he should go to _____________. A. a government office B. a defense system C. an antibody production center D. a doctor or health center 5. _________ can show if one has AIDS. A. Whether one has a defense method against AIDS B. Whether one has unexplained weight loss C. Whether the AIDS antibodies are produced in the body D. The doctor's complete examination Questions 6 to 10 are based on the following passage or dialog. In the United States, about 750,000 persons have suffered from AIDS. More than one half of them have died.

阅读理解自主练习题(5) But doctors say evidence (证据) also shows there is no reason for persons to become terrified (惊 吓) by the disease. The AIDS virus is spread during sex with an infected partner, or by infected blood. But doctors say their studies show the disease is not spread through normal, close social activities. A study by one research team was printed in the New England Journal (杂 志) of Medicine. The doctors studied 101 family members who lived with AIDS and lived in crowded conditions. The family members shared many personal goods with the patients. These included toothbrushes, drinking glasses ,beds, towels, and toilets. Doctors said only one family member—a five-year-old girl—got the AIDS virus. They note, however, that the girl's mother had the disease. They believe the girl probably was born with the virus. No other family member in the study got the AIDS virus or showed any signs of the disease. The head of the study, Gerald Friedland, said if the disease is not easily spread in crowded homes, it also will not spread easily in factorie s, offices, schools, and other public places. Doctor Friedland said the study also shows there is no reason to punish AIDS patients and to force them to live separately from other persons. American health officials recently warned, however, that some health care workers should take special care. The report noted the AIDS virus is carried in blood and other body fluids. It said health care workers should put protec tive (保护性的) covers over their eyes and skin during medical operations, dental (牙科 的) work, or other times when the patient may bleed. In the United States, most AIDS patients are homosexual (同性恋 的) men, people taking drugs who used infected needles and people who received infected blood. More recent stu dies show the AIDS virus also can be spread during heterosexual (异性的) relations. It can spread either from A. Whether one has a defense method against AIDS the man to the woman or from the woman to the man. 6. Doctors say there is no reason for people to be frightened about AIDS because _________. A. it is not deadly B. few people are infected with AIDS C. the AIDS virus is not spread in everyday social activities. D. the AIDS virus is not spread during sex 7. The study of 101 family members who lived with AIDS patients shows that ________. A. AIDS is not spread by using the same personal items B. women are more likely to get the AIDS virus than men C. married men are less likely to get AIDS than unmarried ones D. the AIDS virus is passed by drinking glasses 8. According to Doctor Friedland, there is no reason to _______. A. stop meeting AIDS patients B. stop living with AIDS patients C. fear that AIDS can be passed from a mother to a baby D. fear that the AIDS virus can be passed during sex 9. Health workers were warned to take special care when the patient bleeds because _______. A. AIDS can be passed by touching the patient's body B. AIDS can be spread by touching the patient's skin C. the AIDS virus can be carried in blood or other body fluids D. the health care workers may be infected by the blood 10. _______ are least likely to be infected with the AIDS disease. A. People who use drugs B. Persons who offer infected blood to others C. Men who are gay D. Married men

阅读理解自主练习题(5) Questions 11 to 15 are based on the following passage or dialog. Everyone knows what happens when you catch a cold. First you get a sore throat. Then you sneeze . After coughi ng and blowing your way through the next few days, it's over... until the next time. Every year 69% of Canadians will suffer at least one cold. Colds are responsible for a great deal of lost time at work and at school. There is no known cure for the common cold. Once you catch a cold, your body usually makes antibodies (抗 体) against the virus. These antibodies help the body develop a resistance (抵抗 力) to the virus if you catch it again. Unfortunately, the common cold is caused by over 200 different viruses. The large number of viruses and the fact that they change help explain why there is no cure for the common cold. Adul ts, who have been exposed (遭 受) to more viruses, tend to suffer fewer colds than children. The occurrence of colds tends to increase in the wint er but NOT because of the cold! Cold weather has not been shown to increase the number of colds. People spend more time indoors in winter. They are therefore more likely to come into physical contact with each other and spre ad the disease. Common colds are spread by sneezes or by direct contact with a cold sufferer. Sneezing spreads colds when some one sneezes near other people, or sneezes on objects which others later touch. Once the virus is on someone's hand , and the unsuspecting (毫无戒心 的) victim touches his or her nose or eyes, the virus is spread and trouble begins. The simplest and most effective way to lower the risk of catching a cold is to wash your hands frequently. 11. At the very beginning of the passage, the writer talks about ________. A. what a cold is like B. what a cold virus is like C. how to cure a cold D. how to prevent a cold from spreading 12. There is no cure for the common cold because ________. A. the nature of colds remains unknown B. the large number of cold viruses keeps changing C. your body can't develop antibodies D. your resistance isn't strong enough 13. Which of the following products would have increased sales if more people became aware of the real reason for the spread of colds? A. Sweaters (毛衣). B. Paper napkins (餐巾). C. Soap. D. Bottles of water. 14. People are more likely to catch a cold if they ________. A. go outside in the cold winter B. talk to those who once had colds C. often wash their hands D. always stay indoors and have physical contact with each other 15. Colds are spread by ________. A. sneezes B. direct contacts with a cold sufferer C. touching objects with viruses D. All of the above 答案 1. B 2. D 3. D 4. D 5. C 6. C 7. A 8. B 9. C 10. D 11. A 12. B 13. C 14. D 15. D
