Passage 1
Questions 21 to 25 are based on the following passage.
Hardly a week goes by without some advance in technology that would have seemed incredible 50 years ago.And we can expect the rate of change to accelerate rather than slow down within our lifetime.The developments in technology are bound to have a dramatic effect on the future of work.By 2010, new technology will have revolutionized communications.People will be transmitting messages down telephone lines that previously would have been sent by post.Not only postmen but also clerks and secretaries will vanish in a paper-free society.All the routine tasks they perform will be carried on a tiny silicon chip so that they will be as obsolete as the horse and cart after the invention of the motor car.One change will
make thousands,if not millions,redundant.
Even people in traditional professions,where expert knowledge has been the key,are unlikely to escape the effects of new technology.Instead of going to a solicitor,you might go to a computer which is progammed with all the most up-to-date legal information.Doctors,too,will find that an electronic competitor will be able to carry out a much quicker and more accurate diagnosis and recommend more efficient courses of treatment.In education,teachers will be largely replaced by teaching machines far more knowledgeable than any human being.Most learning will take place in the home via video conferencing.Children will still go to school though ,until another place is created where they can make friends and develop social skills.
What can we do to avoid the threat of unemployment?We shouldn’t hide our heads in the sand.Unions will try to stop change but they will be fighting a losing battle.People should get computer literate as this just might save them from professional extinction.After all,there will be a few jobs left in law,education and medicine for those few individuals who are capable of writing and programming the software of the future.Strangely enough,there will still be jobs like rubbish collection and cleaning as it is tough to programme tasks which are largely unpredictable.

Passage 2
Questions 26 to 30 are based on the following passage.
The World Health Organization says as many as 10 million persons worldwide may have the virus(病毒) that causes AIDS.Experts believe about 350 thousand persons have the disease.And one million more may get it in the next five years.In the United States,about 50,000 persons have died with AIDS.The country’s top medical official says more than 90 percent of all Americans who had the AIDS virus five years ago are dead.
There is no cure for AIDS and no vaccine(疫苗) medicine to prevent it. However,researchers know much more about AIDS than they did just a few years ago.We now know that AIDS is caused by a virus.The virus invades healthy cells including white blood cells that are part of our defense system against disease.It takes control of the healthy cell’s genetic(遗传的) material and forces the cell to make a copy of the virus. The cell then dies.And the viral particles move on to invade and kill more healthy cells.
The AIDS virus is carried in a person’s body fluids.The virus can be passed sexually or by sharing instruments used to take intravenous(静脉内的) drugs.It also can be passed in blood products or from a pregnant woman with AIDS to her developing baby.
Many stories about the spread of AIDS are false.You cannot get AIDS by working or attending school with someone who has the disease.You can not get it by touching,drinking glasses or other objects used by such persons.Experts say no one has gotten AIDS by living with,caring for or touching an AIDS patient.
There are several warning signs of an AIDS infection.They include always feeling tired,unexplained weight loss and uncontrolled expulsion of body wastes(大小便失禁). Other warnings are the appearance of white areas on the mouth ,dark red areas of skin that do not disappear and a higher than normal body temperature.
