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 AIDS 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 that 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 doctor or health center for a complete examination. The doctor may give you an AIDS blood test. When a virus enters 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.

Questions 6 to 10 are based on the following passage or dialog.
cold怎么读In the United States, about 750,000 persons have suffered from AIDS. More than one half of them have died.
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 factories, 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.
