Less TV Reduce Kids Weight
PALO AITO, California—“ Switching off the television may help prevent children from getting fatter—even if they do not change their diet or increase the amount they exercise,” US researchers said last week.
A study of 192 third and fourth grades, generally aged eight and nine, found that children who cut the number of hours spent watching television gained nearly two pounds （0.91 kg ） less over a one-year period than those who did not change their television diet.
“The findings are important because they show that weight loss can only be the result of a reduction in television viewing and not any other activity,” said Thomas Robinson, a pediatrician （儿科专家）at Stanford University.
“ American children spend an average of more than four hours per day watching television and videos or playing games, and rates of childhood being very fat have doubt over the past 20 years,” Robinson said.
In the study, presented this week to the Pediatric Academic Societies’ annual meeting in San Francisco, the researchers persuaded about 100 of the students to reduce their television viewing by one-quarter to one-third.
Children watching fewer hours of television showed a significantly smaller increase in waist size and had less body fat than other students who continue their normal television viewing, even though neither group ate a special diet nor took part in any extra exercise.
“One explanation for the weight loss could be the children unstuck to the television may simply have been moving around and burning off calories,” Robinson said.
“Another reason might be due to eating fewer meals in front of the television. Some studies have suggested that eating in front of the TV encourages people to eat more,” Robinson added.

Phil White has just returned from an 18，000-mile, around-the-world bicycle trip. White had two reasons for making this epic journey. First of all, he wanted to use the trip to raise money for charity, which he did. He raised £ 70，000 for the British charity, Ox-fam. White's second reason for making the trip was to break the world record and become the fastest person to cycle around the world. He is still waiting to find out if he has broken the record or not.
White set off from Trafalgar Square, in London, on 19th June2004 and was back 299 days later. He spent more than 1，300 hours in the saddle (车座）and destroyed four sets of tyres and three bike chains. He had the adventures of his life crossing Europe, the Middle East, India, Asia, Australia, New Zealand and the America. Amazingly, he did all of these with absolutely no support team. No jeep carrying food, water and medicine. No doctor. Nothing ！ Just a bike and a very, very long road.
The journey was lonely and desperate at times. He also had to fight his way across deserts, through jungles and over mountains. He cycled through heavy rain and temperatures of up to 45 degrees, all to help people in need. There were other dangers along the road. In Iran, he was chased by armed robbers and was lucky to escape with his life and the little money he had. The worst thing that happened to him was having to cycle into a headwind on a road that crosses the south of Australia. For 1，000 kilometres he battled against the wind that was constantly pushing him. This part of the trip was slow, hard work and depressing, but he made it in the end. Now Mr. White is back and intends to write a book about his adventures.

The greatest artistic creative geniuses I've ever seen, have been those who can turn garbage into art. Not just gluing together junk, but really making waste into something unique, cool, and well, something you, d put into your home for instance. There's something to be said about recycling of those items we commonly throw away.
The ability to take trash and garbage and turn it into art, or something intriguing that is fascinating to look at is a skill all of its own. I have often said that the true geniuses of our time, that is to say the creative genius artists of our era, are those who can do this-creating art that can command a high price tag from junk. 0ver the years while traveling through the United States I had stopped into museums in many parts of the country.
Some of the best art I've ever seen in my life has come from garbage, trash, or junk that has been reworked and recycled into something spectacular. Best of all the artists don't spend much on material costs, therefore it is mostly profitable. In fact they are using their minds to do a lot with very little. Just think if we all used our minds to do this, how little we might actually throw away, and how more efficiently we could run our factories, production, and even households.
After all, anything that is not used is waste, and it is thrown away. It ends up in a landfill, or a dump somewhere, and eventually it decays in the soil, causing perhaps ground water pollution. However, if we can rework these items for a couple of more rounds, and waste less, then we are providing efficiency for our civilization, and that's a good thing. Any artist who can do this is not only one caring the environment, but also one with humanity, and using his brain power and creative genius to make us all better. What would be the best title for the passage?
| A．Garbage in art out |
| B．Recycle garbage in a new way |
| C．A new kind of art |
| D．A new way to protect the environment |
The author believes the art work created from junk __________.
| A．is not suitable to be put in our home |

| A．The author can't afford good art from garbage. |
| B．Art made from garbage doesn't cost much in material. |
| C．The author collects a lot of art from garbage. |
| D．The author thinks it's easy to make art from garbage. |

| A．real artists are those with humanity |
| B．creating art from garbage can also help the environment |
| C．there is no good way to deal with waste today |
| D．a great amount of waste has been reused by artists |

Twelve years ago, a young traveler named Rhett Butler from San Francisco, California, visited the Sabah rain forest on Malaysian Borneo. In one area of the rain forest, he watched a bird flying through the trees. The beautiful sight left quite an impression on him. But weeks later, back home, Rhett Butler got the news that trees had been cut down in the area he visited.
That experience led Rhett Butler to begin writing a book about rainforests and the threats to their existence. But he did not publish the book. Instead, in 1999，he used his research for the book to create a website. The site is Mongabay, com. His purpose was to inform the public about tropical rain forests. But the subject quickly developed. As a former businessman , he became a respected writer of science and environmental stories.
The popularity of Mongabay. com attracted advertisers. Small ads on the site pay for its operations. Mongabay. com has grown and led to other sites. For example, there is a site for children which is called kids, Mongabay. com. Another one, Wild Madangascar. org, is also about the island nation that Rhett Butler calls his favorite place.
To keep his website going, he travels around the world on several major trips each year. His working tools are a laptop computer, cameras and sometimes diving equipment. He often calls on experts for information. For example, he interviewed Alison Jolly, a top experts on lemurs (狐猴）. He interviewed Rodney Jackson, a biologist who established the Snow Leopard Conservancy.

None of our early ancestors could digest milk as adults because their bodies never had to—milk drinking simply wasn't an option. As people began to extract milk from animals, though, some people developed the ability to keep drinking it throughout their lives.
Scientists now know of a milk-related mutation (变异）in our genes—the chemical instructions for life that we carry in almost every cell in our bodies. People who have a mutated form of one particular gene can drink milk just fine. People without the mutation tend to get sick from milk.
To figure out where, and possibly why, milk drinking started, some scientists have been looking at who has the milk-digesting mutation today. Patterns are striking.
Most adults in Northern and Central Europe are able to digest milk—and they do. Cheese and butter and other dairy products are popular in countries such as Sweden, Denmark, Germany and England. Because European settlers dominated North America, most people here can handle milk just fine, as well. That may explain why ice cream is such a popular dessert in the United States.
In much of Africa, Asia and South America, on the other hand, people tend to avoid dairy products because they lead to diarrhea(腹泻)and other stomach problems (That's why you won't typically find cheese on the menu at a Chinese, Japanese or Ethiopian restaurant. ). Native Americans are also unable to digest milk.
Based on these genetic patterns, scientists have long thought that milk drinking started in Northern Europe, where dairy is an institution and the milk-digesting mutation is everywhere.
A recent study painted a different picture. With a computer medal, Thomas and colleagues looked at the spread of the milk-drinking mutation, farming and other related factors. Working back-ward, the scientists concluded that the first milk-drinkers lived in Central Europe around what's now Hungary about 7，500 years ago. The practice didn't start farther north, as scientists had thought be-fore. Which of the following is the proper order of events according to the passage?
a. Their children were able to digest milk as adults.
b. They got sick from the milk.
c. Some people got a mutation in their genes.
d. Some people tried drinking milk from animals.
e. Some people started to drink milk from animals on a regular basis.
| A．c→d→b→e→a | B．d→e→b→c→a |
| C．d→b→e→c→a | D．e→d→b→c→a |
