Too much TV-watching can harm children’s ability to learn and even reduce their chances of getting a college degree, new studies suggest in the latest effort to examine the effects of television on children.
One of the studies looked at nearly 400northern California third-graders. Those with TVs in their bedrooms scored about eight points lower on math and language arts tests than children without bedroom TVs.
A second study ,looking at nearly 1000 grown-ups in New Zealand, found lower education levels among 26-year –olds who had watched lots of TV during childhood .But the results don’t prove that TV is the cause and don't ride out that already poorly motivated youngsters（年轻人）may wash lots of TV.
Their study measured the TV habits of 26-year-olds between ages5 and 15. These with college degrees had watched拍average of tess than two hours of TV per weeknight during childhood, compared with an average of me than 2 1/2 hours for those who had no education beyond high school
In the California study, children with TVs in their rooms but no computer at home scored the lowest while those with no bedroom TV but who had home computers scored the highest
While this study does not prove that bedroom TV sets caused the lower scores , it adds to accumulating findings that children shouldn’t have TVs in their bedroomsAccording to the Califomia study, the low-scoring group might 。
| A．have watched a lot of TV |
| B．not be interested ted in math |
| C．be unable to go to college |
| D．have had computers in their bedrooms |
What is the researchers' understanding of tbe New Zealand study results?
| A．Poorly motivated 26-year-olds watch more TV. |
| B．Habits of TV watching reduce learning interest[来 |
| C．TV watching leads to lower education levels of the 15-year-olds. |
| D．The connection between TV and education levels is difficult to explain |
What can we learn from the last two paragraphs?
A．More time should be spent on computers.
B．Children should be forbidden from watching TV.
B．TV sets shouldn't be allowed in children's bedrooms
D．Further studies on high-achieving students should be doneWhat would be the best title for this text?
| A．Computers or Television |
| B．Effects of Television on Children |

More American people take their troubles with them on holiday, according to a new survey. Although 40 percent said that the main reason for going away is to escape pressure from work, almost all said they worry more than they do at home. Only four in every 100 said that they are happy and free of care.
The most common worry is burglary(入室盗窃), with four out of 10 worrying about their homes being broken into while they’re abroad. More than a quarter fear they will feel crazy with some other noisy and rough holiday-makers and 22 percent worry they may be attacked or their possessions will be missing. One in five think the car may break down, and the same number worry about the chances of bad weather.
The survey also showed that the stay-at-home Americans are no more. Three out of every five want to have a holiday abroad, a great increase from the figures only three years ago. The hotel holiday is still a winner, with about one third of all Americans preferring to go on a self-catering(自助) holiday.The underlined word “survey” in the first paragraph most probably means _______.
| A．research | B．review | C．exhibition | D．examination |
according to the text, about _____ of people worry more on holiday than when they are at home.
| A．25% | B．40% | C．80% | D．95% |
The third most common worry of American holiday-makers is that they may______.
| A．be attacked or lose their possessions |
| B．have problems with their cars on the road |
| C．have bad weather on holiday |
| D．get mixed with some rough fellow holiday-makers |
Where do American holiday-makers like to stay most?
| A．At a hotel. | B．In a quiet place. |
| C．At a friend’s house. | D．Where they can cook for themselves. |
There are two kinds of physical activity which require special training. The first demands exact careful movements of the muscles. This kind of activity must be strictly controlled because even a slight movement in the wrong direction will lead a mistake. To type quickly, for example, a person needs training; the slightest movement of a finger in the wrong direction may cause a spelling mistake. A dancer who has to dance on the point of her shoes or turn around on one foot must be trained for a long period of time before she can sense her own center and balance herself. You may have seen a girl walking on a rope across an empty space, which, too, requires a lot of practice.
The second kind of physical activity needs greater strength or extra effort. Most of us get tired if we try to run half a mile without stopping, but a specially-trained person can do this without much effort. Three years ago, some scientists carried out experiments, which produced meaningful and unexpected results. They wanted to find out whether a certain amount of physical exercise would injure those suffering from heart problems. They selected some male patients and trained them in continuous bicycle riding. They were surprised to find that the harmful effect of given amount of physical effort was actually less on the hearts of these trained patients than on those of the patients who were not similarly trained. This is important because it shows that regular physical exercise enables us to make better use of the oxygen we breathe in and that this training, in fact, reduces the amount of work our hearts do. Many tasks which are hard for untrained people are not hard at all for trained people.The first kind of physical activity must be strictly controlled because _________.
| A．a mistake in the wrong direction is dangerous to the fingers |
| B．a wrong movement in a direction will cause no mistakes |
| C．a movement in the wrong direction will cause a mistake |
| D．a slight movement of a finger will lead to a mistake |
What must a dancer do before she can balance herself?
| A．She must dance on the point of her shoes. |
| B．She must receive long-time training. |
| C．She must turn around on one foot. |
| D．She must perform again and again. |
The experiments done by some scientists showed that ________.
| A．some male patients were asked to ride bicycles regularly in the experiments |
| B．the physical exercise had more harmful effect on the hearts of the untrained patients |
| C．the physical exercise was harmless to the male patients with heart trouble |
| D．the physical exercise could be helpful for the patients to take in more oxygen |
What would be the best title for this text?

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 |

It is normal for parents to question their children's hairstyle or the clothes they wear. But today teenagers and their parents argue over something else: money.
Children are spending lots of it. Parents used to say to their children, "You're wearing that?" Now they say, "You paid how much for that?"
Children in the US today spend five times more money than their parents did when they were young.
So what are all these children buying? The list is long: ipods trainers(训练鞋), cellphones and jeans are typical items that children "have to" buy. And they will do anything to get them. They ask their parents over and over until they buy them.
But parents also need to take the blame for spending so much money. They want their children to have the best stuff. They end up competing with other parents over what their children have.
So no wonder children find it hard to learn the importance of saving money rather than spending it all the time.
And it's hard to save when companies use advertising and clever slogans to encourage young people to buy their products. They even encourage children to keep asking their parents for something until they get it.
Today, you don't even need to have money in order to buy something. Banks give out credit cards and loans all the time so people are saving less and less. We are used to there being lots of money around. And if you don't have much you can always borrow some.
But this hasn't always been the case. When our grandparents were young there was very little money and everyone had to save hard for things they bought. They only bought things they needed, not things they just wanted.
The older generation made the wise expression, "Money doesn’t grow on trees." This is as true now as it was 50 years ago. They give money a great deal of value. And we all have a lot to learn from them.The text mainly tells us ________.
| A．divisions between teenagers and their parents |
| B．children's high consumption (消费) of products |
| C．what is popular among children at the moment |
| D．how to spend money wisely |
Parents are to blame for children's spending a lot of money because ________.
| A．they encourage children to care about the latest fashion |
| B．their consumption habits set a bad example for children |
| C．they always give children too much pocket money |
| D．they do nothing to help children establish healthy consumption habits |
Nowadays people find it hard to save money because of all of the following reasons EXCEPT that ________.
| A．banks provide credit cards and loans |
| B．advertisements draw people’s attention to new products |
| C．people have more money than in the past and saving is out of date |
| D．people's living standard has improved and they can buy what they want |
The saying "Money doesn't grow on trees." in the last paragraph is intended to tell us that ________.
| A．the older generation understood how to teach children to save |
| B．in the past, people attached more importance to saving money |
| C．money has a great deal of value |
| D．money is not easily earned and people should be careful spending it |
