听力原文:M: Today so many people are talking about AIDS. Is the AIDS epidemic very serious
now?

W: Oh, yeah. To say the impact on our society, this disease will be the most serious public-health problem we are facing now. On a global scale, it threatens to undermine countries, especially in Africa.

M: Oh, it's so terrible? What do you mean by "undermine countries"?

W: It is a very serious disease in the middle ages of the population, so that it will greatly reduce the number of people carrying out the functions of the society. In parts of Africa, it's happening already.

M: We know that AIDS is mainly caused by sex contact and blood exchange or drug abuse. Do you think people's basic behavior. can be altered in time to stop the AIDS epidemic?

W: In time to have a significant impact, yes. I don't think we'll be perfect. People will respond differently. But for the homosexual population in San Francisco, the rate of homosexually transmitted diseases fell dramatically when a serious educational program was put in place. People were obviously willing to change their behavior. when they were made to realize how severe a risk they were taking.

M: What about groups not yet hard hit? Can the message get to them before massive death occurs?

W: It is certainly harder to reach people when they don't see the consequence of what they're doing right around them or when the consequence is extremely delayed.

M: How can we reach people?

W: A massive educational campaign is the only thing conceivable at the moment that can help. To argue that it's difficult and expensive and therefore we shouldn't do it would be self-defeating.

A.The epidemic of AIDS.

B.The treatment of AIDS.

Supersize Surprise

Ask anyone why there is an obesity epidemic and they will tell you that it's all down to eating too much and burning too few calories. That explanation appeals to common sense and has dominated efforts to get to the root of the obesity epidemic and reverse it. Yet obesity researchers are increasingly dissatisfied with it. Many now believe that something else must have changed in our environment to precipitate (促成) such dramatic rises in obesity over the past 40 years or so. Nobody is saying that the "big two"--reduced physical activity and increased availability of food--are not important contributors to the epidemic, but they cannot explain it all.

Earlier this year a review paper by 20 obesity experts set out the 7 most plausible alternative explanations for the epidemic. Here they are.

1. Not enough sleep

It is widely believed that sleep is for the brain, not the body. Could a shortage of shut-eye also be helping to make us fat?

Several large-scale studies suggest there may be a link. People who sleep less than 7 hours a night tend to have a higher body mass index than people who sleep more, according to data gathered by the US National Health and Nutrition Examination Survey. Similarly, the US Nurses' Health Study, which tracked 68,000 women for 16 years, found that those who slept an average of 5 hours a night gained more weight during the study period than women who slept 6 hours, who in turn gained more than those who slept 7.

It's well known that obesity impairs sleep, so perhaps people get fat first and sleep less afterwards. But the nurses' study suggests that it can work in the other direction too: sleep loss may precipitate weight gain.

Although getting figures is difficult, it appears that we really are sleeping less. In 1960 people in the US slept an average of 8.5 hours per night. A 2002 poll by the National Sleep Foundation suggests that the average has fallen to under 7 hours, and the decline is mirrored by the increase in obesity.

2. Climate control

We humans, like all warm-blooded animals, can keep our core body temperatures pretty much constant regardless of what's going on in the world around us. We do this by altering our metabolic (新陈代谢) rate, shivering or sweating. Keeping warm and staying cool take energy unless we are in the "thermo-neutral zone", which is increasingly where we choose to live and work.

There is no denying that ambient temperatures (环境温度) have change in the past few decades. Between 1970 and 2000, the average British home warmed from a chilly 13℃ to 18℃. In the US, the changes have been at the other end of the thermometer as the proportion of homes with air conditioning rose from 23% to 47% between 1978 and 1997. In the southern states--where obesity rates tend to be highest--the number of houses with air conditioning has shot up to 70% from 37% in 1978.

Could air conditioning in summer and heating in winter really make a difference to our weight? Sadly, there is some evidence that it does--at least with regard to heating. Studies show that in comfortable temperatures we use less energy.

3. Less smoking

Bad news: smokers really do tend to be thinner than the rest of us, and quitting really does pack on the pounds, though no one is sure why. It probably has something to do with the fact that nicotine (尼古丁) is an appetite suppressant and appears to up your metabolic rate.

Katherine Flegal and colleagues at the US National Center for Health Statistics in Hyattsville, Maryland, have calculated that people kicking the habit have been responsible for a small but significant portion of the US epidemic of fatness. From data collected around 1991 by the US National Health and Nutrition Examination Survey, they worked out that people who had quit in the previous decade were much more likely to be overweigh
