PALO ALTO, 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 graders, generally aged eight and nine, found that children who cut the number of hours spent watching television gained nearly two pounds(0.9kg) 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 video games, and rates of childhood being very fat have doubled 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 continued their normal television viewing, even though neither group ate a special diet or 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 more 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 said.The author tries to tell us in the first two paragraphs that ________.
| A．children will get fatter if they eat too much |
| B．children will get thinner if they eat less |
| C．children will get fatter if they spend less time watching TV |

Australia’s koalas could be dying out within 30 years, unless urgent measures is taken to stop the losing in population, according to researchers. They say development, climate change and bushfires have all related to reduce the number of wild koalas sharply. The Australian Koala Foundation said a recent survey showed the population could have dropped by more than half in the past six years. Previous estimates put the number of koalas at more than 100,000, but the latest figures suggest there could now be as few as 43,000.
The foundation collected field data from 1,800 sites and 80,000 trees to calculate the numbers. In one area in northern Queensland estimated to have 20,000 koalas a decade ago, a team of eight people could not find a single animal in four days of searching.
The foundation said besides problems caused by cutting down forests, hotter and drier conditions because of global warming had reduced the nutritional(营养的)value of their staple food, eucalyptus leaves, leading to poor nutrition for them.
Koalas, which live in the forests in Australia’s east and south, are very particular about what types of the leaves they eat.
Foundation chief Deborah Tabart said: “The koalas are missing everywhere we look. It’s really no tree, no me. If you keep cutting down trees you don’t have any koalas.”She is hoping the new figures will persuade the government’s Threatened Species Steering Committee (TSSC) to list the koala as threatened. But committee chairman Bob Beeton said a decision was not likely recently and the koala’s status as one of the country’s favorite animals would not be a factor. “There’s a number of species which are attractive and people have special feelings towards them. We don’t consider that,” Mr. Beeton was reported as saying by the AFP agency.The writer gives the example of the area in northern Queensland in Paragraph 3 to show that _____.
| A．the environment is being polluted seriously |
| B．the number of koalas is dropping quickly |
| C．the forests are being damaged heavily |
| D．koalas usually live in wild mountainous areas |
Global warming is an important cause of koalas’ reduction because _____.
| A．the leaves koalas eat are losing nutritional value |
| B．koalas cannot get enough water to drink |
| C．koalas can hardly stand the hot weather |
| D．the leaves koalas eat cannot grow in hot weather |
According to Bob Beeton, _____.
| A．they needn’t pay special attention to koalas |
| B．a decision will be made to protect koalas |
| C．koalas are his favorite animals |
| D．koalas needn’t be protected at all |
Most people feel lonely sometimes, but it usually only lasts between a few minutes and a few hours. This kind of loneliness is not serious. In fact, it is quite normal. For some people, though, loneliness can last for years. Now researchers say there are three different types of loneliness.
The first kind of loneliness is temporary. This is the most common type. It usually disappears quickly and does not require any special attention. The second kind is situation, for example, family problem, the death of loved one, or moving to a new place. Although this kind of loneliness can cause physical problems, such as headaches and sleeplessness, it usually does not last for more than a year. The third kind of loneliness is the most serious. Unlike the second type, chronic (the opposite of “temporary”) usually lasts more than two years and has no specific cause. People who experience habitual loneliness have problems socializing and becoming close to others. However, many chronically lonely people think there is little or nothing they can do to improve their condition.
Psychologists agree that one important factor in loneliness is a person’s social contacts, for example, friends, family members, co-workers, etc. We depend on various people for different reasons. For instance, our families give us emotional support, our parents and teachers give us guidance, and our friends share similar interests and activities. However, psychologists have found that, though lonely people may have many social contacts, they sometimes feel they should have more. They question their popularity.
Psychologists are trying to find ways to help habitually lonely people for two reasons: they are unhappy and unable to socialize and there is a connection between chronic loneliness and serious illness such as heart disease, while temporary and situational loneliness can be a sad, and sometimes dangerous condition. How would you treat temporary loneliness according to the passage? ________.
| A． Just ignore it |
| B．Talk to friends |
| C．Go to see a doctor |
| D．Ask your teachers for guidance |
Why do psychologists want to help chronically lonely people? ________
| A．Chronic loneliness can cause family problems. |
| B．Chronic loneliness can not be overcome. |
| C．Chronic loneliness can cause serious illness. |
| D．Chronic loneliness is incurable. |
Loneliness is divided according to _____.
| A．different seasons when it appears |
| B．different people it happens to |
| C．the time it lasts |
| D．the places where it appears |
What is the best title for the passage? ________
| A． Loneliness and diseases |
| B．Three kinds of loneliness |
| C．Loneliness and social contacts |
| D．Chronic loneliness |
Lakes, ponds, and beaches mean summer fun and cool relaxation from hot weather．But water also can be dangerous for kids if you don't take great care．Nearly 1,000 kids die each year by drowning．Here are some tips to keep your kids safe in the water:
At the Lake or Pond
●Don't let little kids swim alone without adult supervision— lakes or ponds may be shallow near the bank and are suddenly deep sharply further out from shore．
●Ponds and lakes may hide sharp rocks, broken glass, or rubbish．
●Make sure kids wear foot protection; even in the water, they should wear socks or water shoes．
●Watch out for weeds and grass in the water that could trap a leg or arm．
●Most boating accidents, particularly among teenagers, are related to alcohol．Be sure teens know about the dangers of alcohol, on and off the water．

Every morning Grandpa got up early sitting at the table, reading his book. His grandson wanted to be just like him and tried to copy him in every way he could.
One day the grandson asked, “Grandpa, I try to read the book just like you, but I don’t understand it, and I forget what I understand as soon as I close the book. What good does reading the book do?” The grandpa quietly turned from putting coal in the stove and replied, “Take this coal basket down to the river and bring me back a basket of water.”
The boy did as he was told, but all the water leaked out before he got back to the house. The grandpa laughed and said, “You’ll have to move a little faster next time,” and sent him back to the river with the basket to try again.
This time the boy ran faster, but again the basket was empty before he returned. Out of breath, he told his grandpa that it was impossible to carry water in a basket, so he went to get a bucket instead. The grandpa said, “I don’t want a bucket of water; I want a basket of water. You’re just not trying hard enough.”
The boy again dipped the basket into the river and ran hard, but when he reached his grandpa the basket was empty again. Out of breath, he said, “Grandpa, it’s useless !”“So, you think it is useless?” the grandpa said, “Look at the basket.”
