(判断)AIDS, fifty years ago, didn’t exist.Fifteen years ago a few doctors and public health officials noticed the first cases.Within a few years it was clear that it has now killed almost 14 million people around the world.
Four years ago doctors came up with the first treatment to make a dent in the spiraling death rate.Today that treatment works for some patients, but it’s not clear how long results will last.And still there is no cure.
For the nearly 35 million people around the world now living with HIV, there may never be a cure.Once cells are infected with HIV, it is very difficult — perhaps impossible ―to rid them of the virus.The only sure way to stop AIDS is to prevent infection in the first place, and only a vaccine can do that.
Unfortunately HIV is one of the most changeable viruses known to science.After more than a dozen years, it is still rather difficult to produce effective vaccine.
Still the billions of dollars spent on AIDS research over the past 20 years has not been wasted.As scientists learn more about how HIV survives in the human body, they are realizing that drugs alone may not be enough.To contain the virus effectively, it may take a balance between drug treatments that can keep HIV levels low and a strengthened immune system that can then target and destroy the remaining virus.Until scientists find a vaccine, however, they may control but never cure the century’s final scourge.
46.AIDS didn’t exist fifteen years ago.
47.Scientists have found a vaccine which can prevent HIV infection.
48.Although some treatment works for some patients with HIV, there is still no cure.
49.HIV is a changeable virus so that it is very difficult to produce effective vaccine.
50.We have wasted billions of dollars on AIDS research.

How hard is it to get into one of the top medical schools, like for example the one at Yale University in Connecticut？ Last year almost three thousand seven hundred students hoped to get accepted there. Only one hundred seventy-six -- or less than five percent -- were admitted.
People who want to become medical doctors often study large amounts of biology, chemistry and other science. Some students work for a year or two in a medical or research job before they try to get accepted to medical school.
Medical students spend their first two years in classroom study. They learn about the body and all of its systems. And they begin studying diseases -- how to recognize and treat them. By the third year, students guided by experienced doctors begin working with patients in hospitals. As the students watch and learn, they think about the kind of medicine they would like to practice as doctors. During the fourth year, students begin applying to hospital programs for the additional training they will need after medical school. Competition for a residency at a top hospital can be fierce.
A medical education can be very costly, especially at a private school. One year at a private medical college can cost forty thousand dollars or more. The average at a public medical school is more than fifteen thousand dollars. Most students have to take out loans to pay for medical school. Many finish their education heavily in debt.
Doctors are among the highest paid professionals in the United States. Specialists in big cities are generally the highest paid. But there are also doctors who earn considerably less, including those in poor communities.
(1)Which of the following ideas is NOT suggested in the passage？
A、It is hard to get into one of the top medical schools.
B、The United States has more than one hundred twenty medical colleges.
C、Medical students need two years' classroom study.
D、After graduating from medical schools, the students become doctors.
(2)How many years the medical students take to graduate from medical school？
A、2
B、3
C、4
D、1
(3)In what way many medical students pay for their medical education？
A、Have part-time jobs in hospitals.
B、Take out loans.
C、Their parents pay for it.
D、Work hard for the scholarship.
(4)What the medical students begin to do in their fourth year of study？
A、Looking for a job.
B、Working with patients in hospitals
C、Applying to hospital programs for the additional training.
D、Learning about the body and all of its systems
(5)_______ are generally the highest paid.
A、Specialists in big cities.
B、Experienced doctors.

D、Doctors who graduated from private medical schools.

第5题
A prescription is as personal as your name. It is designed for you alone. It is based on such factors as your age, weight, general health, allergies (过敏症), and other factors, as well as your illness.
Never take a prescription drug meant for another person, even if you think you have the same illness. Prescriptions aren't supposed to be traded around the family or neighborhood. Each prescription is intended for an individual. It is a violation of federal law to sell a prescription drug without a prescription.
Doctors and dentists are licensed by each state to prescribe drugs for human use. Doctors for veterinary (兽医的) medicine are licensed to prescribe drugs for animal use.
A licensed medical doctor must pass all examination m practice medicine in a certain state. Before doing this, he or she has probably completed at least two years of a premedical course, a four-year medical course, two years of internship (实习) or residency in a hospital, and perhaps an extra year or more of training in a specialty -- altogether at least eight years of medical training, possibly nine.
Don't take prescriptions written for you during a previous illness without first checking with your doctor. Your illness may not be the same as the previous one, even though you think it is. Also the drug may have lost strength. Only a doctor is qualified to advise you about continuing to take a medicine.
Why does the law require that some drugs be used under a doctor's prescription？
A．Because they are not safe.
B．Because they need further special tests.
C．Because they are meant to cure serious diseases.
D．Because the prescription can ensure the safe use of the drugs.

第10题
The Economic and Social Research Council, which gives grants to postgraduate social scientists, wants to get better value for money by cutting short this agony. It would like to see faster completion rates: until recently, only about 25 % of PhD candidates were finishing within four years. The ESRC's response has been to stop PhD grants to all institutions where the proportion taking less than four years is below 10%; in the first year of this policy the national average shot up to 39%. The ESRC feels vindicated in its toughness, and will progressively raise the threshold to 40% in two years. Unless completion rates improve further, this would exclude 55 out of 73 universities and polytechnics-including Oxford University, the London School of Economics and the London Business School.
Predictably, howls of protest have come from the universities, who view the blacklisting of whole institutions as arbitrary and negative. They point out that many of the best students go quickly into jobs where they can apply their research skills, but consequently take longer to finish their theses. Polytechnics with as few as two PhD candidates complain that they are penalized by random fluctuations in student performance. The colleges say there is no hard evidence to prove that faster completion rates result from greater efficiency rather than lower standards or less ambitious doctoral topics.
The ESRC thinks it might not be a bad thing if PhD students were more modest in their aims. It would prefer to see more systematic teaching of research skills and fewer unrealistic expectations placed on young men and women who are undertaking their first piece of serious research. So in future its grants will be given only where it is convinced that students are being trained as researchers, rather than carrying out purely knowledge-based studies.
The ESRC can not dictate the standard of thesis required by external examiners, or force departments to give graduates more teaching time. The most it can do is to try to persuade universities to change their ways. Recalcitrant professors should note that students want more research training and a less elaborate style. of thesis, too.
By the time new doctors get a job and try to finish their theses in spare time ______.
A．most of them died of some sickness
B．their holidays and evenings have been ruined by their jobs
C．most of them are completely tired of the narrowly defined subject
D．most of their grants run out
