Today's youngsters are already falling prey to potential killers such as diabetes because of their weight. Fatty fast-food diets combined with sedentary lifestyles dominated by televisions and computers could mean kids will die tragically young, says Professor Andrew Prentice, from the London School of Hygiene and Tropical Medicine.
At the same time, the shape of the human body is going through a huge evolutionary shift because adults are getting so fat. Here in Britain, latest research shows that the average waist size for a man is 36～38 in and may be 42～44 in by 2032.
This compares with only 32.6 in in 1972. Women's waists have grown from an average of 22in in 1920 to 24 ins in the Fifties and 30in now. One of the major reasons why children now are at greater risk is that we are getting fatter younger. In the UK alone, more than one million under--16s are classed as overweight or obese-double the number in the mid-Eighties. One in ten four-year- olds are also medically classified as obese. The obesity pandemic--an extensive epidemic--which started in the US, has now spread to Europe, Australia, Central America and the Middle East.
Many nations now record more than 20 per cent of their population as clinically obese and well over half the population as overweight. Prof Prentice said the change in our shape has been caused by a glut of easily available high-energy foods combined with a dramatic drop in the energy we use as a result of technology developments.
He is not alone in his concern. Only last week one medical journal revealed how obesity was fuelling a rise in cancer cases. Obesity also increases the risk factor for strokes and heart disease. An averagely obese person's lifespan is shortened by around nine years while a severely obese person by many more. Prof Prentice said. "So will parents outlive their children, as claimed recently by an American obesity specialist？" The answer is yes-and no. Yes, when the offspring become grossly obese. This is now becoming an alarmingly common occurrence in the US. Such children and adolescents have a greatly reduced quality of life in terms of both their physical and psychosocial health. So say No to that doughnut and burger.
What does the word "sedentary (Line 2, Para. 2)" mean？
The success of chain schools is to some extent because of the marketing and advertising.
听力原文： Amsterdam, the Netherland's capital, is one of the world's best tourist destinations, where you can immerse yourself in history, in art, in the head of a beer.
Any time can be the best time to visit. The summer months are wonderful as the whole city seems to live outdoors, but it's also the peak tourist season, when hotels are full and expensive. From mid-October to mid-March the climate is miserable, but there are fewer tourists, things are cheaper and cultural life is at its most authentic. The shoulder seasons can offer the best of both worlds.
Many of the world's airlines fly directly to Amsterdam, and it is extremely convenient to fly to Amsterdam from China. But it might be cheaper for you to fly to a nearby city such as London and get to Amsterdam by bus or train. Many airlines will offer you a free side trip within Europe, so ask around and see what offers are available.
Amsterdam is well connected to the rest of Europe, including Britain, by long-distance bus. Buses are consistently cheaper than trains, but on some services you'll get a lungful of cigarette smoke. Freeways link Amsterdam to The Hague, Rotterdam. The Netherlands are very amenable to cycling —this is one of the flattest places in the world, and there are dedicated bike paths throughout the country. Amsterdam has 550,000 bicycles and this is an ideal way to get around, although you need to get used to the idea of having your bike stolen. If you're going to be around for more than a month, consider buying a second-hand bike, and make sure you buy a lock as well.

M: What does it look like I am doing？
W: Well, it looks like you are watching television. But we have an exam tomorrow, so I thought you'd be studying for it and maybe I can study with you.
M: Oh, well, I was just taking a break. The books give me a headache if I work on it too long.
W: I know what you mean. I've been working on it for three hours already.
M: But I can't believe you are coming to me. I mean you do know what I got on the last test, don't you？
W: Yeah, I know. You told me. I just thought two heads might be better than one.
M: That's nice idea. But... you know, I wish I knew that person in our class who got a hundred on the last test. She didn't miss a question. Umm... was it Julie？
W: Oh yeah, Julie! She is a friend of mine. She'd be a big help right now. Why don't I give her a call？
M: What! At this hour？ It's already ten thirty.
W: I guess you are tight. But you know what, she owes me a big favor. Let's at least give her a call and see what she says. Maybe going over some of the problems with us would help her review the material.
M: It's worth a try.
