New Attempts to Eradicate AIDS Virus
A high-profile attempt to eradicate the AIDS virus in a few patients continues to show promise.
But researchers wont know for a year or more whether it will work, scientist David Ho told journalists here Wednesday for the Fourth Conference in Viruses and Infections.
This is a study thats in progress, says Ho, head of the Aaron Diamond AIDS Research Center, New York.
The study involves 20 people who started combinations of anti-HIV drugs very early in the course of the disease, within 90 days of their infections. Theyve been treated for up to 18 months. Four others have dropped out because of side effects or problems complying with the exacting drug system.
The drugs have knocked the AIDS virus down to undetectable levels in the blood of all remaining patients. And, in the latest development, scientists have now tested lymph nodes and semen from a few patients and found no virus reproducing there, Ho says. Bear in mind that undetectable does not equal absent, Ho says.
Ho has calculated that the drugs should be able to wipe out remaining viruses at least from known reservoirs throughout the body in two to three years. But the only way to prove eradication would be to stop the drugs and see if the virus comes back. On Wednesday, Ho said he wouldnt ask any patient to consider that step before 2 (1/2) years of treatment.
And he emphasized that he is not urging widespread adoption of such early, aggressive treatment outside of trials. No one knows the long-term risks.
But other scientists are looking at similar experiments. A federally funded study will put 300 patients on triple-drug treatments and then see if some responding well after six months can continue to suppress the virus on just one or two drugs, says researcher Douglas Richman of the University of California, San Diego. Some patients in that study also may be offered the chance to stop therapy after 18 months or more, he says.
31. According to the passage， the attempt to eradicate the AIDS virus
A.hasnt been made seriously
B.is appreciated by California University
C.continues to show promise
D.will be successful in two and a half years
答案：C
32. Which is NOT true about Hos study?
A. 20 patients were involved in the study
B. The patients have used several anti-HIV drugs

答案：C
33. The words Bear in mind undetectable does not equal absent by Hos means
A. AIDS virus can be undetectable in the blood.
B. AIDS virus is undetectable in the blood.
C. No AIDS virus can be detected in the blood.
D. No virus found in the blood means no AIDS.
答案：A
34. We prove that the drugs have wiped out the remaining viruses by
A. using up all the drugs at once.
B. waiting for the virus to die slowly.
C. asking the patients feeling about the disease.
D. stopping the drugs to see if the virus comes back.
答案：D
35. Other scientists are looking at experiments that are similar in that they are

Gross National Happiness
In the last century， new technology improved the lives of many people in many countries. However， one country resisted these changes. High in the Himalayan mountains of Asia， the kingdom of Bhutan remained separate. Its people and Buddhist(佛教)culture had not been affected for almost a thousand years. Bhutan， however， was a poor country. People died at a young age. Most of its people could not read， and they did not know much about the outside world. Then， in 1972， a new ruler named King Jigme Singye Wangchuck decided to help Bhutan to become modern， but without losing its traditions.
King Wangchuck looked at other countries for ideas. He saw that most countries measured their progress by their Gross Natonal Product(GNP). The GNP measures products and money. When the number of products sold increases people say the country is making progress. King Wangchuck had a different idea for Bhutan. He wanted to measure his countrys progress by peoples happiness. If the peoples happiness increased， the king could say that Bhutan was making progress. To decide if people were happier， he created a measure called Gross National Happiness(GNH).
GNH is based on certain principles that create happiness. People are happier if they have health care, education, and jobs. They are happier when they live in a healthy, protected environment. They are happier when they can keep their traditional culture and customs. Finally, people are happier when they have a good, stable government.
Now these is some evidence of increased GNH in Bhutan. People are healthier and are living longer. More people are educated and employed. Teenty-five percent of the land has become national parks, and the country has almost no pollution. The Bhutanese continue to wear their traditional clothing and follow their ancient Buddhist customs. Bhutan has also become a democracy. In 2008, King Wangchuck gave his power to his son. Although the country still had a king, it held its first democratic elections that year. Bhutan had political parties and political candidates for the first time. Finally, Bhutan has connected to the rest of the world through television and internet.
Bhutan is a symbol for social progress. Many countries are now interested in Bhutans GNH. These countries are investigating their own ways to measure happiness. They want to create new policies that take care of their people, cultures, and land.
Brazil may be the nest country to use the principles of GNH. Brazilian leaders see the principles of GNH as a source of inspiration. Brazil is a large country with a diverse population. If happiness works as a measure of progress in Brazil, perhaps the rest of the world will follow.
36. Who was Jigme Singye Wangchuck?
A. A president.
B. A buddist preist.
C. A general.
D. A king.
答案：D
37. Apart from moderizing Bhutan, what else did Wangchuck want to do for Bhutan?
A. To make its populaton grow.
B. To keep it separate from the world.
C. To encourage its people to get rich.
D. To keep its tradition and customs.
答案：D
38. A country shows its progress with GNP by
A. selling more products.
B. spending more money.
C. spending less money.
D. providing more jobs.
答案：A
39. According to GNH, people are happier if they
A. have new tecnology.
B. can change their religion.
C. have a good, stable government.
D. have more money.
答案：C
40. Today, many countries are
A. using the principles of GNH to measure their progress.
B. woking together to develop a common scale to measure GNH.
C. taking both Bhutan and Brazil as symbols for social progress.
D. trying to find their own ways to measure happiness.
答案：D

Genetic Engineering
Genetic engineering began when the DNA molecule(分子), the most basic unit of life, was first described in 1953 by James Watson and Francis Crick. An understanding of DNA led to the altering of normal cell reproduction. Experiments with altering human cells began in 1970. In one of the first experiments, patients were injected with a virus that would produce a life-saving enzyme, but their bodies would not accept it. In 1980 patients with a rare but fatal blood disease were injected with a purified gene that was cloned through DNA technology. Another failure.
Genetic engineering got a legal boost(激励) in 1980. The U.S. Supreme Court said that a patent could be granted on a genetically engineered oil-eating bacterium(细菌). This bacterium would help clean up oil spills. The ruling encouraged companies to invent new life forms, and three important medical products were quickly developed.
l Human interferon(干扰素)-- a possible solution to some cancers and viral disease. A newly engineered bacterium produced human interferon as a by-product. This new product reduced the cost of interferon.
l Human growth hormone-- for children whose bodies do not grow to normal height. An expensive growth hormone(荷尔蒙) was previously produced from human cadavers, but by changing the genetic make-up of the single-cell bacterium E. coli, and affordable growth hormone could be produced.
l Human insulin(胰岛素)-- for the treatment of diabetes. People with diabetes used to rely on a beef- or pork-based product until 1982. Now insulin can be manufactured by genetically altered bacteria.
Advances in genetic engineering have continued, though they constantly must be weighted against the safety of procedures. There is clearly much more to discover.

A. the effects of altering cells.
B. the human growth hormone.

Voice Your OpinionChange is Needed in Youth Sports
Everywhere you look， you see kids bouncing a basketball or waving a tennis racquet (网球拍)。 And these kids are getting younger and younger. In some countries， children can compete on basketball， baseball， and volleyball teams starting at age nine. (46)And swimming and gymnastics classes begin at age four， to prepare children for competition.
Its true that a few of these kids will develop into highly skilled athletes andmay even become members of the national Olympic teams. (47) This emphasis oncompetition in sports is having serious negative effects.
Children who get involved in competitive sports at a young age often grow tired of their sport. Many parents pressure their kids to choose one sport and devote all their time to it. (48) But 66 percent of the young athletes wanted to play more than one sport-for fun.
Another problem is the pressure imposed by over-competitive parents and coaches. Children are not naturally competitive. In fact， a recent study by Paulo David found that most children dont even understand the idea of competition until they are seven years old. (49)
The third， and biggest， problem for young athletes is the lack of time to do their homework， have fun， be with friendsin short， time to be kids. When they are forced to spend every afternoon at sports practice， they often start to hate their chosen sport. A searchers found that 70 percent of kids who take part in competitive sports before the of twelve quit before they turn eighteen. (50) Excessive competitive away all the enjoyment.
Need to remember the purpose of youth sports to give kids a chance to have developing strong， healthy bodies.
