INDLANAPOLIS—Doctors and health advocates （提倡者）have warned for years that American children are getting fatter. Now even some kids’ teddy bears are packing on the pounds.
But these heavy toys aim to combat（对抗）obesity, not add to it.
Researchers at Indiana State University in Terre Haute tried a small experiment to test the effects of having kids play with heavier toys. They found that 10 children aged 6 to 8 burned more calories and had higher heart and breathing rate when they moved 3-pound toy blocks instead of unweighted blocks.
So could adding a small weight to stuffed animals and other toys help kids get fit?
“This is not going to solve the obesity problem,” said John Ozmun, a professor who did the study with graduate student Lee Robbins. “But it has been possible to make a positive contribution.”
Some experts cautioned that children could hurt themselves by trying to lift too much too soon and said more activity is preferable to heavier toys. But all agreed that childhood obesity is a big problem.
Obesity rate has become three times over the past 40 years for children and adolescents, raising the risk of diabetes（糖尿病）and other health problems. Federal health officials say more than a third of American children are overweight, and about 17 percent are considered obese（肥胖的）.
“Squeezing activity into daily routines can be a good way for children to get more exercise and shed unhealthy pounds,” said Aicia Moag-Stahlberg, who heads Action for Healthy Kids.
“By adding weights, you’re adding some intensity to the action,” she said.
Kara Tucker, youth development coordinator for the National institute for Fitness and Sport in Indianapolis, said active playing helps youngsters work out without realising it.
“Giant soccer is one of my favorites,” Tucker said. “If we told the kids, ‘Hey, you’re going to run up and down the court 20 times,’ they would completely be uninterested. Yet when we put a big soccer ball out there, they will just run forever. They’re having a great time.”

You might think that “global warming” means nothing more than a rise in the world’s temperature But rising sea levels caused by it have resulted in the first evacuation（撤离）of an island nation—the citizens of Tuvalu will have to leave their homeland.
During the 20th century , sea level rose 8—12 inches. As a result ,Tuvalu has experienced lowland flooding of salt water which has polluted the country’s drinking water.
Paani Laupepa , a Tuvaluan government official ,reported to the Earth Policy Institute that the nation suffered an unusually high number of fierce storms in the past ten years .Many scientists connect higher surface water temperatures resulting from global warming to greater and more damaging storms.
Laupepa expressed dissatisfaction with the United States for refusing to sign the Kyoto Protocol, an international agreement calling for industrialized nations to reduce their greenhouse gas emissions（导致温室效应的气体排放）,which are a main cause of global warming . “By refusing to sign the agreement ,the US has effectively taken away the freedom of future generations of Tuvaluans to live where their forefathers have lived for thousands of years,” Laupepa told the BBC.
Tuvalu has asked Australia and New Zealand to allow the gradual move of its people to both countries .
Tuvalu is not the only country that is vulnerable （易受影响的）to rising sea levels .Maumoon Gayoon ,president of the Maldives ,told the United Nations that global warming has made his country of 311,000 an “endangered nation”. The text is mainly about .
| A．rapid changes in earth’s temperature |
| B．bad effects of global warming |
| C．moving of a country to a new place |
| D．reasons for lowland flooding |
According to scientists ,the direct cause of more and fiercer storms is .
| A．greenhouse gas emissions in industrialized nations |
| B．higher surface water temperatures of the sea |
| C．continuous global warming |
| D．rising sea levels |
Laupepa was not satisfied with the United States because it did not .
| A．agree to reduce its greenhouse gas emissions |
| B．sign an agreement with Tuvalu |
| C．allow Tuvaluans to move to the US |
| D．believe the problems facing Tuvalu were real |
The country whose situation is similar to that of Tuvalu is .
| A．Australia | B．New Zealand | C．the Maldives | D．the United States |
My husband, my four-month-old daughter and I set out on a five-day driving journey from California to Washington. We had to stop frequently because our little child needed to stretch from the car seat.
One of our stops, once we crossed the Oregon border, was at a Black Bear Diner. Walking towards the front door we noticed a gentleman standing at one side. He was clearly untidy, without shoes and wearing worn clothing. We passed right by him and opened the restaurant door. Then something told me to go back.
Holding my daughter, I turned around and said to the gentleman, “Sir. Are you hungry?” He said, “Yes.” I then asked, “May we buy you something to eat?” He responded with, “Sure, I can order something myself.”
My husband opened the door and the gentleman went straight to the counter. I told him to order whatever he wanted. The manager of the restaurant came over quite quickly and looked frightened. I spoke before he had an opportunity to. “This gentleman will have lunch with us today,” I said. “Please add his order to our bill.” The manager said with a frown(皱眉), “Okay.” We turned to our table and the gentleman said, loudly and quickly, “Thank You!” We were seated and upon completing our meal we were handed our bill. I asked my husband what the gentleman had ordered. One fresh orange juice, one coffee, one breakfast combination with a side of hash browns.
When we left the restaurant I looked for the gentleman but didn’t see him, but that very small act just made my day. I hope in some small way we were able to add some joy to his life, even if only for a few minutes.From the appearance of the gentleman, we can guess he was probably a(n) _____.
| A．waiter | B．actor | C．beggar | D．worker |
The manager of the restaurant looked frightened because _____.
| A．the man was not friendly |
| B．he had fired the man before |
| C．the man had stolen something from the restaurant |
| D．he was afraid the man wouldn’t afford to pay the food |
From the passage, we can infer the man _____.
| A．was thankful for their kind act |
| B．felt ashamed and slipped away |
| C．was hungry and ate a lot of food |
| D．was too proud to accept their offer |
The phrase “made my day” in the last paragraph probably means ______.
| A．wasted my money | B．moved me deeply |
| C．made me feel sorry | D．made me very happy |
Little Mark is only 6, but he has an IQ of 200, a genius among geniuses. But his intelligence comes at a cost. His parents must keep him intellectually simulated（启发）while making sure he is like any other little boy.
Mark has been attracted by the way how the world works since he was a baby. When he was 3, Mark was reading fluently, mostly self-taught. His parents haven't been able to keep him away from books since.
"I tried many times to stop him reading. We worry about his crazy fond of reading because he constantly wants to read every-thing whatever it is.”
A psychologist at the Centre for gifted children tested Mark and gave him an IQ of 200. The average child of Mark's age has an IQ of 100. At 200, Mark is a genius-even compared with other child geniuses.
"With children like Mark you can tell that's a bright child as soon as they walk in. They just have this sort of intensity, and maybe they're not so good at communicating with people," the psychologist said. "He will never fit perfectly into a class where he's with children of his age.”
But Mark's mother worries about the "socially isolated" labels. "Nobody wants their child to grow up with that image. I want him to communicate with others freely, but not to be frustrated academically, so it's really hard to find a balance," she says.
Helen Dudeney from the Talented and Gifted Children Association says Mark is one in a million with such a high IQ. She points out that geniuses are still rare and difficult for the public education system to handle. "The lack of coping comes because teachers aren't trained in teaching gifted children," says Dudeney.
Helen believes it's also extremely important for them to be recognized and supported in their talents. Mark's parents are trying to figure out how best to help Mark. At the moment, there are few options. Mark finds first year work boring and simple, but he must learn to complete the work. His mother says, "We just want to be happy. Just to have a happy childhood and want to go to school every day.”By saying "But his intelligence comes at a cost. ",the author means that
| A．Mark must pay for his intelligence at a high price |
| B．Mark's intelligence brings him negative effects at the same time |
| C．Mark's intelligence results from his parents |
| D．Mark's parents make Mark clever at all costs |
Which of the following is NOT true according to the passage?
| A．Mark's parents are very satisfied with his love for reading. |
| B．Mark began to teach himself reading at the age of 3. |
| C．Many child geniuses are not good at communicating with others. |
| D．It is hard for parents to bring up a genius. |
If there are 6. 6 billion people in the world, the number of geniuses with an IQ of 200 will be________．
| A．about 4,400 | B．about 5,500 | C．about 6,600 | D．about 7,700 |
What would be the best title for the passage?
| A．A genius' craziness for books |
| B．The life of the genius' parents |
| C．The burden of being gifted |
| D．The characteristics of Mark |
Every year thousands of tourists visit Pompeii, Italy. They see the sight that Pompeii is famous for—its stadium and theaters, its shops and restaurants. The tourists do not, however, see Pompeii’s people. No one has lived in Pompeii for almost 2,ooo years.
Once Pompeii was a busy city of 22,000 people. It lay at the foot of Mt Vesuvius, a grass-covered volcano. Mt Vesuvius had not erupted for centuries, so the people of Pompeii felt safe. But they were not. In August of the year 79 AD, Mt Vesuvius erupted. The entire top of the mountain exploded, and a huge black cloud rose into the air. Soon stones and hot ashes began to fall on Pompeii. When the eruption ended two days later, Pompeii was buried under 20 feet of stones and ashes. Almost all of its people were dead.
For centuries, Pompeii lay buried under stones and ashes. Then in the year 1861, an Italian scientist named Ginseppe began to uncover Pompeii. Slowly, carefully, Ginseppe and his men dug. The city almost looked the same as it had looked in 79 AD. There were streets and fountains, houses and shops. There was a stadium with 20,000 seats. Perhaps the most important of all, there were everyday objects, which tell us a great deal about the people who lived in Pompeii. Many glasses and jars had some dark blue color in the bottom, so we know that the people of Pompeii liked wine. They liked bread too; metal bread pans were in every bakery. In one bakery there were 81 round, flat loaves of bread—a type of bread that is still sold in Italy today. Tiny boxes filled with a dark, shiny powder tell us that women liked to wear eye-makeup.
Ginseppe has died, but his work continues. One-fourth has not been uncovered yet. Scientists are still digging, still making discoveries that draw the tourists to Pompeii. Why do large number of people come to Pompeii each year?
| A．To visit the volcano. | B．To shop and eat there. |
| C．To watch sports and plays. | D．To see how Pompeiians lived. |
Why did the city uncovered look almost the same as it had looked in 79 AD ?
| A．Because Ginseppe and his men dug it slowly and carefully. |
| B．Because the city was buried alive and remained untouched. |
| C．Because scientists successfully rebuilt the city with everyday objects. |
| D．Because nobody had lived in the city ever since the volcano erupted. |
What do we know about the Pompeiians who lived 2,000 years ago?
A. They lived more or less the same as Italians now do.
B. They liked women wearing all kinds of makeup.
C. They enjoyed a lazy life with drinking and eating.
D. They went back to Pompeii after the eruption in 79 AD.
As a youngster, there was nothing I liked better than Sunday afternoons at my grandfather’s farm in western Pennsylvania. Surrounded by miles of winding stone walls, the house and field provided endless hours of fun for a city kid like me. I was used to tidy living rooms that seemed to whisper, "Not to be touched!"
I can still remember one afternoon when I was eight years old. Since my first visit to the farm, I had wanted more than anything to be allowed to climb the stone walls surrounding the houses. My parents would never approve. The walls were old; some stones were missing, others loose and falling. Still, my idea to climb across those walls grew so strong that finally, one spring afternoon, I had all my courage to enter the living room, where the adults had gathered after Sunday dinner.
"I, uh-I want to climb the stone walls," I said. Everyone looked up. "Can I climb the stone walls? "Immediately voices of disagreement went up from the women in the room. "Heavens, no!" You'll hurt yourself!" I wasn't too disappointed; the response was just as I'd expected. But before I could leave the room, I was stopped by my grandfather's loud voice. "Now hold on just a minute," I heard him say. "Let the boy climb the stone walls. He has to learn to do things for himself."
Many years have passed since then, and today I host the television program Mister Rogers’ Neighborhood, seen by millions of children throughout America. There have been changes over the years, but one thing remains the same: my message to children at the end of almost every visit. "There's only one person in this whole world like you," the kids can count on hearing me say, "and people can like you exactly as you are.”When the writer was small, he lived.
| A．in the city | B．on the farm |
| C．with his grandparents | D．away from his parents |
The writer enjoyed his visits to the farm because.
| A．there were old stone walls. | B．it was an exciting place for him. |
| C．he liked his grandfather. | D．the living room there was clean |
The underlined word “approve” in paragraph 2 means.
| A．prove | B．suppose | C．allow | D．mind |
We can learn from the passage that the writer was.
| A．adventurous | B．funny | C．smart | D．talkative |
