AIDS
The World Health Organization(WHO)says as many as 10 million persons worldwide
may have the virus that causes AIDS（艾滋病）.Experts believe about 350, 000 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）or medicine to prevent it. However,
researchers know much more about AIDS than they did」ust 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 material and forces the cell to make a copy of the virus.The cell then dies.And the
virus-caused 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（进入静脉的）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 cannot 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.
It is unlikely that the AIDS virus wil}be passed through handshaking.

[不定项选择题]共用题干
Health care in the US is well known but very expensive.Paying the doctor's bill after a major illness or accident can cost hundreds of thousands of dollars.
In the US,a person's company,not the government,pays for health insurance.Employers have contracts with insurance companies,which pay for all or part of employees' doctors' bills.
The amount that the insurance company will pay out to a patient differs wildly.It all depends on what insurance the employer pays.The less the boss pays to the insurance company,the more the employee has to pay the hospital each time he or she gets sick.In 2004,the average worker paid an extra $558 a year,according to a San Francisco report.
The system also means many Americans fall through the cracks（遭遗漏）.In 2004,only 61 percent of the population received health insurance through their employers,according to the report. The unemployed,self-employed,part-time workers and graduated students with no jobs were not included.
Most US university students have a gap between their last day of school and their first day on the job.Often,they are no longer protected by their parents' insurance because they are now considered independent adults.They also cannot buy university health insurance because they are no longer students.
Another group that falls through the gap of the US system is international students.All are required to have health insurance and cannot begin their classes without it. But exact policies（保险单）differ from school to school.
Most universities work with health insurance companies and sell their own standard plan for students.Often,buying the school plan is required,but luckily it's also cheaper than buying directly from the insurance company.
The international students in the US work harder than the American students.
