Children are getting so fat that they may be the first generation to die before their parents, an expert says.
Today's young people will be affected by potential (潜在的) killers such as heart disease because of their weight. Fatty fast-food diets combined with the lifestyles with televisions and computers could mean kids will die 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 great change because adults are getting so fat.
Here in Britain, the latest research shows that the average waist size for a man is 36~38 inches and may be 42~44 inches by 2032.This compares with only 32.6 inches in 1972. Women's waists have grown from an average of 22 inches in the 1920s to 24 inches in the 1950s and 30 inches 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 16 years old are thought
to be overweight or fat—double the number in the 1980s. One in ten of four-year-olds are also medically said to be obese.
The obesity which started in the US, has now spread to Europe, Australia, Central America and the Middle East. Many nations now record more than 20 percent of their population as obese and well over half of the population as overweight.
Professor Prentice says the change in our shape has been caused by high-energy foods combined with a dramatic (急剧的) drop in the energy we use as a result of technology developments.
He is not alone in his concern. Only last week one medical magazine revealed how obesity was fuelling a rise in cancer cases. Obesity also increases the risk factor for heart disease and so on. An averagely obese person's lifespan (寿命) is shortened by around nine years while a seriously obese person by much more.
Professor Prentice says,
“So_will_parents_live_longer_than_their_children,_as_an_American_obesity_expert_said_recently?”
“The answer is yes—and no.” Yes, when most children become obese. No, because this is now becoming an alarmingly serious problem in the US. “Such children will have a greatly reduced quality of life on both body and mind.”

On the day Apple debuted the often-delayed white-colored iPhone 4, the company's marketing department gave a nod to the product's troubled history.
"Finally." read the big headline Thursday above a picture of the white phone on the homepage of Apple.com.
The white model was supposed to ship alongside the black one at the iPhone 4's launch(推出) last June.But design and manufacturing complications delayed the process by 10 months, catching Apple off guard, executives say.
As CNN reported last month, earlier test models of the white iPhone 4 produced unclear photos, especially when the flash(闪光灯) was used.Its whiteness confused the proximity sensor (距离传感器) , which detects when the phone is held next to someone's head and turns off the touch screen to save battery life.
These problems weren't present in older iPhones that came in white because they didn't have flash photography; the proximity sensor was unaffected because the front side of previous models was black.
"We thought we were there a year ago, or less than that, when we launched the iPhone 4, and we weren't," Philip Schiller, Apple's chief marketing executive, said in an interview."It's not as simple as making something white.There's a lot more that goes into both the material science of it —how it holds up over time…but also in how it all works with the sensors."
Ticonderoga Securities analyst Brian White predicts that the white model could help drive sales of Apple's phones.He says Apple could sell 1 million to 1.5 million every three months until the next iPhone model is unveiled, which is expected to be this fall.
Forty-five people were lined up at Apple's flagship New York store Thursday morning to buy white iPhones, according to a CNN Money report.The reason why white-colored iPhone 4 was delayed by 10 months is that _______.
A.it's always sold out due to its popularity |
B.it met some problems concerning design and manufacture |
C.it lacked white manufacturing materials |
D.its proximity sensor can't save battery life |
According to the passage, which of the following statements is TRUE?
A.There are multi-colored models of iPhone 4. |
B.The same design problems were also found in older white iPhones. |
C.IPhone4 will be launched this fall. |
D.Originally designers thought they could solve the problems before iPhone 4 was launched. |
What would be the best title for this passage?

A characteristic of American culture that has become almost a tradition is to respect the self-made man —the man who has risen to the top through his own efforts, usually beginning by working with his hands.While the leader in business or industry or the college professor occupies a higher social position and commands greater respect m the community than the common laborer or even the skilled factory worker, he may take pains to point out that his father started life in America as a farmer or laborer of some sort.
This attitude toward manual (体力的) labor is now still seen in many aspects of American life.One is invited to dinner at a home that is not only comfortably but even luxuriously (豪华地) furnished and in which there is every evidence of the fact that the family has been able to afford foreign travel, expensive hobbies, and college education for the children; yet the hostess probably will cook the dinner herself, wil2 serve it herself and will wash dishes afterward, furthermore the dinner will not consist merely of something quickly and easily assembled from contents of various cans and a cake or a pie bought at the nearby bakery.On the contrary, the hostess usually takes pride in careful preparation of special dishes.A professional man may talk about washing the car, digging in his flowerbeds, painting the house.His wife may even help with these things, just as he often helps her with the dishwashing.The son who is away at college may wait on table and wash dishes for his living, or during the summer he may work with a construction gang on a highway in order to pay for his education.From paragraph 1, we can know that in America _____.
A.people tend to have a high opinion of the self-made man
B.people can always rise to the top through their own efforts
C.college professors win great respect from common workers
C.college professors feel it painful to mention their fathers as labors.According to the passage, the hostess cooks dinner herself mainly because ______.
A.servants in American are hard to get |
B.she takes pride in what she can do herself |
C.she can hardly afford servants |
D.It is easy to prepare a meal with canned food |

Annealing is a way of making metal softer by heating it and then letting it cool very slowly. If metal is heated and then cooled very quickly, for example by dipping (浸) it in water, it will be very hard but also very brittle (脆) —that is , it will break easily. Metal that has been annealed is soft but does not break as easily. It is possible to make metal as hard or as soft as is wished, by annealing it. The metal is heated, and allowed to cool slowly for a certain length of time. The longer the heated metal takes to cool slowly, the softer it becomes. Annealing can also be used on other materials, such as glass. Annealing can make metal
A.hard and tough (韧). | B.hard but brittle. |
C.soft but tough. | D.soft and brittle. |
Why do people put hot metal in water?
A.To make it hard. | B.To make it soft. |
C.To ma![]() |
D.To make it brittle. |

n glass be made less brittle?
A.It can be heated and then cooled quickly. |
B.It can be cooled and then heated slowly. |
C.It can be heated and then cooled slowly. |
D.It can be cooled and then heated quickly. |
