AIDS researchers say they still have much work to do on a vaccine (疫苗) against HIV. But the first reports of some success have raised hopes.    1  

The study was designed to test for two abilities. One was the ability of the vaccine to prevent HIV infections. The other was its ability to reduce the amount of virus in the blood of people who became infected during the study.

Volunteers received vaccinations over a period of six months and were tested for HIV for an additional three years. The study began in 2003. It was the largest AIDS vaccine trial yet.  2    Half received the vaccine. The other half received a placeho, an inactive substance (物质). The volunteers did not know which they were getting.

Seventy-four people in the placeho group became infected during the study.    3    Doctor Supachai Rerks-Ngarm, who led the study for the Thai Ministry of Public Health, called it a scientific breakthrough.

The National Institutes of Health also took part. Doctor Anthony Fauci at NIH called the findings an important step forward.    4    But he also said additional research was needed to better understand how the vaccine reduced the risk in those individuals.

The vaccine did not lower the amount of virus in the blood of volunteers who became infected during the study. The study was based on versions of HIV commonly found in Thailand. The volunteers received a combination of two vaccines.    5   The second, or booster, vaccine was developed by VaxGen. The nonprofit group Global Solution for Infectious Diseases now has rights to it.

Neither vaccine had been successful by itself when tested earlier. More detailed results of the study are expected to be presented at an AIDS vaccine conference in Paris next month.

A. The first, or prime, vaccine came from the Sanofi Pasteur company.

B. The AIDS vaccine raises hopes for those who get infected and will defeat the disease

thoroughly.

C. Scientists say an experimental vaccine reduced the risk of infection in humans by thirsty-one percent and was safe.

D. The researchers say that was compared with only fifty-one of those who received the vaccine.

E. AIDS is a very serious phenomenon in Thailand.

F. It involved more than sixteen thousand adults in Thailand.

G. He said it represented the first time an investigational HIV vaccine had shown some ability to prevent infection.

A. Social background for the Development of Adult Education

B. What is the present situation?

C. The purposes in Adult Education

D. Ways of Adult Education

E. The history of Adult Education

F. What is Adult Education?

61                

Voluntary learning in organized courses by mature men and women is called adult education. Such education is offered to make people able to enlarge and interpret their experience as adults. Adults may want to study something which they missed in earlier schooling, get new skills or job training, find out about new technological development, seek better self-understanding, or develop new talents and skills.

62                

   This kind of education may be in the form of self-study with proper guidance through the use of libraries, correspondence(函授)courses,or broadcasting.It may also be acquired collectively in schools and colleges, study groups, workshops, clubs, and professional associations.

63                

Modern adult education for large numbers of people started in the 18th and 19th centuries with the rise of the Industrial Revolution. Great economic and social changes were taking place: people were moving from rural areas to cities: new types of work were being created in an expanding factory system. These and other factors produced a need for further education and reeducation of adults.

64                

The earliest program of organized adult education arose in Great Britain in the 1790s, with the founding of an adult school at Nottingham and a mechanics’institute at Glasgow. The earliest adult education institution in the United States was founded by Benjamin Franklin and some friends in Philadelphia in 1727.

65                

People recognize that continued learning is necessary for most forms of employment today. For example, parts of the adult population in many countries find it necessary to take part in retraining programs at work or even to learn completely new jobs. Adult education programs are springing up constantly to meet these and other needs.

根据短文内容,从短文后的选项中选出能填入空白处的最佳选项,选项中有两项为多余选项。

Is bottled water better for you than tap? Or should you choose vitamin-enriched water? Experts say, skip it all. None of these products is likely to make you any healthier. Below, we look at four major myths about the benefits of drinking water. 71 Experts say there’s an easy way to judge. If you are not thirsty, your fluid intake is likely “just right”

Myth No 1: Drink eight glasses each day.

Scientists say there’s no clear health benefit of drinking so much water a day. 72 “Nobody really knows,” says Dr. Stanley Goldfarb, a kidney expert at the University.of Pennsylvania.

Myth No.2Lots of water equals healthier skin.

The body is already 60 percent water. 73 Adding a few extra glasses of water each day has a limited effect. “It’s such a tiny part of what’s in the body,” says Goldfarb. “ It’s very unlikely that one’s getting any benefit.”

Myth No.3: 74

A more accurate statement may be: Drinking water is a helpful tool for dieters. “Water is a great strategy for dieters because it has no calories,” says Madeline Fernstrom of the University of Pittsburgh. “So you can keep your mouth busy without food and get a sense of satisfaction.” But water is not magical, she adds. “Other zero-calorie options such as diet sodas are fine, too.”

Myth No. 4: It’s easy to get dehydrated(脱水的) during a workout.

Dehydration sets in when a person has lost 2 percent of his or her body weight. 75 “It’s also obvious that individuals in hot, dry climates have an increased need for water,” says Goldfarb. “But for a walk in the park, no water bottle is necessary.”

A.     So where does the standard advice come from?

B.      But it’s unclear whether these changes are clinically significant.

C.     So for a 200-pound man, this means losing 4 pounds of water.

D.     Drinking extra water leads to weight loss.

E.      Drink as much water as you can.

F.      So, if you take a 200-pound man, he’s 120 pounds of water.

G.But first, how do you know if you’re drinking enough water?
