An experimental treatment that causes AIDS patients to develop a dangerously high fever has shown promise as a way of prolonging and improving the patients’ life.Called the Biologic-HT System, the new treatment lets doctors extract the blood of a patient and heat it before circulating it back into the body. The heated blood causes the patient’s body temperature to rise above 42 degrees Celsius. In people with AIDS, that increase in temperature kills some heat-sensitive HIV, the virus, most doctors say, causes AIDS.
Heating the blood of AIDS patients has been tried before, say doctors. But during previous attempts, the treatment induced deadly chemical changes in the blood. The Biologic-HT System prevents those changes from happening, allowing the heat to kill viruses with few ill side effects.
The new heat treatment cannot be considered a cure for Aids, says president of the company that makes the system. He says the treatment doesn’t kill all traces of the virus. However, it kills enough virus particles to give a patient’s immune system a reprieve in its deadly duel with HIV.
Tests of the Biologic-HT treatment began on 36 patients earlier this year. The treatment takes about four hours, and the patient normally feels well enough to leave the hospital or clinic the following morning.
So far, the patients who have had the treatment say they feel better and have developed no new opportunistic infections—disease that strike people with damaged immune systems. The patients also have experienced about a 50 percent increase in the number of T cells in their bodies. T cells are key disease-fighting cells of the immune system and the main target of HIV.
1.This passage is mainly concerned with ____________.
A. a way for treating AIDS
B. a heat-sensitive virus
C. the immune system of the human body
D. the function of high temperature
2.The blood of the patient___________.
A. is heated with a single injection
B. is heated by being circulated at a higher rate
C. is taken out from the body and then circulated through a heating system.

3.The previous attempts to use high temperature for treating AIDS failed because they_________.
A.caused chemical changes
B.could not kill HIV effectively
C.resulted in deaths
D.killed both HIV and healthy cells
4.According to the passage, the new treatment___________.
A.can kill all the HIV viruses
B.cannot eliminate the viruses completely
C. can double the number of disease-fighting cells
D.can reconstruct the patient’s immune system.
5.The result of the experiment seems to be ___________.

Shortness of breath has many different causes, and the treatment of it is specific for each cause. 1.There are, however, some following first aid steps you can use to treat it, at least until the ambulance arrives or you're able to get the victim to a hospital.
2. The more energy you spend, the more oxygen you use and the more short of breath you feel. Think about a good workout at the gym. Exercise hard enough and you will feel short of breath. The cure? Take a break.
Let the victim sit, stand or lie where’s the most comfortable. There're lots of myths about how some body positions supposedly provide more airflow. Coaches regularly tell players to hold their arms above their heads to maximize chest expansion. Nursing staff think the ''tripod position'' is the best position. 3.
Use oxygen. This is a special case used only for people with chronic(慢性的)lung problems. If the victim has oxygen available, this is what it's for. 4. The victim may have been told by his or her doctor that too much oxygen for too long might cause more problems. Make sure the victim that sudden increases in shortness of breath are the instances in which oxygen is needed most.
Treat the cause of shortness of breath. 5. Asthma(哮喘)patients, for example, often have multiple tools and drugs to fix sudden shortness of breath. Victims of lung infections may need to see a doctor and heart attack victims may need an ambulance.
A. Have the victim rest.
B. Take more exercise at the gym.
C. The victim should use his or her oxygen as directed by a doctor.
D. There're many causes of shortness of breath and many of them are treatable.
E. The victim can try to avoid making use of his or her oxygen whenever possible.
F. Every person is different, however, so let the victim decide what position feels most comfortable.
G. In many cases, the only way to treat shortness of breath is to call 911or take the victim to a doctor.

An "apple polisher" is one who gives gifts to win friendship or special treatment.It is not exactly a bribe(贿赂), but is close to it.
All sorts of people are apple polishers,including politicians and people in high offices—just about everybody. Oliver Cromwell,the great English leader,offered many gifts to win the support of George Fox and his party,but failed.
There are other phrases meaning the same thing as "apple-polishing"—"soft-soaping" or "butter-up".A gift is just one way to "soft-soap" somebody,or to "butter him up".Another that is just as effective is flattery,giving someone high praise—telling him how good he looks,or how well he speaks,or how talented and wise he is.
Endless are the ways of flattery.Who does not love or hear it?Only an unusual man can resist the thrill of being told how wonderful he is.In truth,flattery is good medicine for most of us,who gets so little of it.
We need it to be more sure of ourselves.It cannot hurt unless we get carried away by it.But we just lap it up for its food value and nourishment,as a cat laps up milk,then we can still remain true to ourselves.
Sometimes,however,flattery will get you nothing from one who has had too much of it.A good example is the famous 12th century legend of King Canute of Denmark and England.The king got tired of listening to the endless sickening flattery of his courtiers(朝臣).They over-praised him to the skies,as a man of limitless power.
He decided to teach them a lesson.He took them to the seashore and sat down.Then he ordered the waves to stop coming in.The tide was too busy to listen to him.The king was satisfied.This might show his followers how weak his power was and how empty their flattery.
1.Which of the following activities has nothing to do with "apple-polishing"?
A. A boy tells his girlfriend how pretty she looks
B. An employee tells his boss how good he is at management
C. A knight is said to be of limitless power by his followers
D. A teacher praised his students for their hard work
2.King Canute of Denmark and England took his followers to the seashore because_______.
A. he was sick of his normal
B. he wanted them to realize how wise he was
C. he did not like being over-praised any more
D. he wanted them to see how weak he was as a king
3.The author thinks that flattery can do good to those who_______.
A. lack confidence B. are really excellent
C. are politicians or in high offices D. think highly of themselves
