Prolonging human life has increased the size of the human population. Many people alive today would have died of childhood diseases if they had been born 100 years ago. Because more people live longer, there are more people around at any given time. In fact, it is a decrease in death rates, not an increase in birthrates, that has led to the population explosion.

Prolonging human life has also increased the dependency load. In all societies, people who are disabled or too young or too old to work are dependent on the rest of society to provide for them. In hunting and gathering cultures, old people who could not keep up might be left behind to die. In times of famine, infants might be allowed to die because they could not survive if their parents starved, where as if the parents survived they could have another child. In most contemporary(當(dāng)代的) societies, people feel a moral obligation to keep people alive whether they can work or not. We have a great many people today who live past the age at which they want to work or are able to work; we also have rules which require people to retire at a certain age. Unless these people were able to save money for their retirement, somebody else must support them. In the United States many retired people live on social security checks which are so little that they must live in near poverty. Older people have more illnesses than young or middle-aged people; unless they have wealth or private or government insurance, they must often “go on welfare” if they have a serious illness.

When older people become senile (衰老的) or too weak and ill to care for themselves, they create grave problems for their families. In the past and in some traditional cultures, they would be cared for at home until they died. Today, with most members of a household working or in school, there is often no one at home who can care for a sick or weak person. To meet this need, a great many nursing homes and convalescent (療養(yǎng)的) hospitals have been built. These are often profit making organizations, although some are sponsored by religious and other nonprofit groups. While a few of these institutions are good, most of them are simply “dumping (倒垃圾的) grounds” for the dying in which “care” is given by poorly paid, overworked, and under skilled personnel.

71. The author believes that the population explosion results from _______.

A. an increase in birthrates                          B. the industrial development

C. a decrease in death rates                          D. human beings’ cultural advances

72. It can be inferred from the passage that in hunting and gathering cultures _______.

A. it was a moral responsibility for the families to keep alive the aged people who could not work

B. the survival of infants was less important than that of their parents in times of starvation

C. old people were given the task of imparting the cultural wisdom of the tribe to new generations

D. death was celebrated as a time of rejoicing for an individual freed of the hardships of life

June 26, 2000—the Human Genome(基因組) Project, a great $3 billion, 15-year task aimed at drawing the genetic(遺傳的)map of humans, is now more than 90 percent completed. The scientific and medical communities are very excited about the chances genetic research provides for getting rid of diseases and prolonging(延長(zhǎng)) human life. But those communities and policy makers are also careful about the scientific door they are opening as the project uncovers the mysteries of life.

       For the last few years, the genetic advances in the developing field of biotechnology have provides material for all kinds of work, but the developments of modern science in unlocking the secrets of the human genetic code have opened a world of possibilities for human health, as well as for the popular imagination.

       While European and Japanese researchers are making rapid progress in decoding(解碼) human DNA, the leading organization for genetic research is in the United States, which began in 1990, is “unlocking the code” of the human body to learn how to defeat fatal diseases. Already, the Human Genome Project has become widely known and praised for finding the genes connected with as yet(迄今) terrible diseases, and making progress toward separating the genes that show a sign of breast cancer or AIDS.

       Once these genes are found and studied, researchers can develop new ways to attack infections, and genetic diseases. Medical companies are very interested in mapping the human genome, as they expect to develop a lot of new drugs for these illnesses.

Why did the scientists work hard at mapping the Human Genome?

A. Because the Human Genome can destroy many illnesses.

       B. Because the Human Genome's completion can help them get rid of many diseases.

       C. Because they wanted to be better known than others.

       D. Because the Human Genome can provide a lot of chances of work.

Which country studied the genes most rapidly in the world?

       A. Japan. B. Germany.       C. The United States.      D. China.

Which of the following is NOT true?

       A. If the genes can be found, scientists can study many new ways to cure illnesses.

       B. The scientists have made great progress in connecting the genes with the cancers.

       C. Many medical companies show great interest in drawing the human genome map.

       D. The United States began the Genes Study early in the 19th century.

The main idea of this article is about_________.

       A. unlocking genetic code         B. the genes' discovery

       C. the great human genome            D. the genes and the scientist

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.
【小題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
【小題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.
D.is taken out from the body, heated outside and then put back into the body.
【小題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
【小題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.
【小題5】The result of the experiment seems to be ___________.
A.disappointingB.incompleteC.successfulD.surprising
