Watching television more than two hours a day early in life can lead to attention problems later in adolescence, according to a study released on Tuesday.
The roughly 40 percent increase in attention problems among heavy TV viewers was observed in both boys and girls. The link was established by a long-term study of the habits and behaviors of more than 1,000 children born in Dunedin, New Zealand, between April 1972 and March 1973.
The children aged 5 to 11 watched an average of 2.05 hours of weekday television. From age 13 to 15, time spent in front of the tube rose to an average of 3.1 hours a day.
"Those who watched more than two hours, and particularly those who watched more than three hours, of television per day during childhood had above-average symptoms of attention problems in adolescence," Carl Landhuis of the University of Otago in Dunedin wrote in his report, published in the journal Pediatrics.
Young children who watched a lot of television were more likely to continue the habit as they got older, but even if they did not the damage was done, the report said.
"This suggests that the effects of childhood viewing on attention may be long lasting," Landhuis wrote.
Landhuis offered several possible explanations for the association.
One was that the rapid scene changes common to many TV programs may over stimulate（刺激）the developing brain of a young child, and could make reality seem boring by comparison. "Hence, children who watch a lot of television may become less tolerant of slower-paced and more mundane tasks, such as school work," he wrote.
It was also possible that TV viewing may supplant other activities that promote concentration, such as reading, games, sports and play, he said.
Previous studies have linked the sedentary固定不动的）habit of TV watching among children to obesity and diabetes, and another study in the same journal cited the poor nutritional content of the overwhelming majority of food products advertised on the top-rated US. children's television shows.
Up to 98 percent of the TV ads promoting food products that were directed at children aged 2 through 11 "were high in either fat, sugar, or sodium," wrote Lisa Powell of the University of Illinois in Chicago.

The UN Security Council was created in 1945. It is made up of 10 rotating (轮值的) members and five permanent members, which have a veto, the power to stop a resolution (决议). Most UN members now consider the organization's structure outdated． But any changes need the agreement of two-thirds of the 191 members, and no veto from any of the five permanent council members.
Last year, Japan, Germany, Brazil and India formed a lobbying (游说) group to get permanent council seats. But North and South Korea have doubts about Japan, Italy opposes Germany for a seat, Pakistan is against India's candidacy (候选资格) and Mexico and Argentina frown on Brazil.
A wave of emotion swept through China last week as millions voiced their opposition to Japan's permanent membership of the United Nations (UN) Security Council. By last Friday over 22 million Chinese had signed an online petition (请愿) against Japan's bid for a permanent seat on the council.
According to major Chinese websites, such as sina.com, more than 170,000 overseas Chinese also signed． This is the first online activity of its kind．
The petition was started by US-based Alliance for Preserving the Truth of the Sino-Japanese War (抗日战争史实维护会). They want Japan to apologize for crimes during World War II. The group also plans to present the petition to the UN this autumn.
Chinese Foreign Ministry spokesman Liu Jianchao said he didn't think the petition shows anti-Japanese feeling. He believed instead it is a request for Japan to take a responsible attitude towards history.What’s the main idea of the first paragraph?

Trouve sat up on its back legs and growled(吼叫) the words, “How are you, Grandmamma?” The audience roared with laughter and clapped. Twenty-year-old Aleck gave the dog a morsel(一口) of food. His hard work had paid off. His dog could talk!
Aleck was fascinated with the different sounds of people’s speech. His father taught students who had a speech problem to improve their speech. Aleck paid close attention. Could an animal form sounds into words, too? He decided to experiment with Trouve, the family dog.
The easy part was teaching Trouve to growl whenever Aleck wanted. The little dog growled for a morsel of food.
Next Aleck moved the dog’s “lips” as it growled. It sounded like “ma mama”. Trouve learned quickly to stop the growling just as Aleck’s hand moved away. They practiced and practiced until the dog said “mama” perfectly.
Soon Aleck discovered more. If he pushed gently under the dog’s jawbone(下颌骨), it made the “ga” sound. If he pushed once and moved the dog’s lips twice, he could make the dog say, “ga mama.” With even more practice, it sounded like “grandmamma”. Whenever Trouve said “grandmamma”, Aleck gave the dog two treats, so Trouve loved the lessons.
Aleck tried to teach his dog to move its tongue so that Trouve could say more words. That didn’t work, but Aleck didn’t give up.
After many hours of practice, Trouve could say, “Ow ah oo ga-ma-ma?” This sounded just like “How are you, Grandmamma?”
Friends and neighbors traveled to see young Aleck and his amazing talking dog. Rumors spread that the dog could speak by itself, which wasn’t true. No matter how much Aleck tried, the dog was never able to move its lips without help.

What contributes most to Aleck’s success in teaching the dog to talk?

The Westborough High School golf team had taken the official photos with the state prize. The other teams, disappointed, were on the bus heading home. And then Westborough instructor Greg Rota noticed something wrong on one of the score cards. A 9 had been recorded as A 7. They were not the state prize winner; Woburn High had won. “No one would have known,” said Woburn’s instructor, Bob Doran. For Rota, it wasn’t a difficult decision: “The prize wasn’t ours to take.”

In bringing up children, every parent watches eagerly the child's acquisition （学会）of each new skill in the first spoken words, the first independent steps, or the beginning of reading and writing．It is often tempting to hurry the child beyond his natural learning rate, but this can set up dangerous feelings of failure and states of worry in the child．This might happen at any stage．A baby might be forced to use a toilet too early, a young child might be encouraged to learn to read before he knows the meaning of the words he reads．On the other hand, though, if a child, is left alone too much, or without any learning opportunities, he loses his natural enthusiasm for life and his desire to find out new things for himself．
Parents vary greatly in their degree of strictness towards their children．Some may be especially strict in money matters; Others are severe （严格的） over time of coming home at night or punctuality for meals．In general, the controls represent the needs of the parents and the values of the community as much as the child's own happiness．
As regards the development of moral standards in the growing child, consistency is very important in parental teaching．To forbid a thing one day and excuse it the next is no foundation for morality （道德）．Also, parents should realize that "example is better than precept"．If they are not sincere and do not practice what they preach （说教）, their children may grow confused when they grow old enough to think for themselves, and realize they have been to some extent fooled．
A sudden awareness of a marked difference between their parents’ principles and their morals can be a dangerous disappointment.Eagerly watching the child’s acquisition of new skills.
| A．will make the child lose interest in learning new things |
| B．sets up dangerous states of worry in the child |
| C．is universal among parents |
| D．should be avoided |
In the process of children’s learning new skills, parents.
| A．should encourage them to read before they know the meaning of the words they read |
| B．should achieve a balance between pushing them too hard and leaving them on their own |
| C．should expect a lot from the children |
| D．should create as many learning opportunities as possible |
In terms of moral matters, parents should.
