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.

Some schools that are not year-round often have summer programs. In many cases, students take summer classes to repeat a subject they failed. This way they get a second chance to succeed. But schools also offer summer classes to students who want to be free of a required class during the next school year.
Generally, students in these classes want to take fewer subjects during the year because they are involved in a lot of activities. They might be involved in sports or music programs. Or both – and more.
These summer school students do the same amount of work as if they took the class during the school year. But they do it in a much shorter time, one or two months. They say it makes for a lot of reading and homework and not much time for anything else. Some education experts are worried about high school students who take summer school because of pressure to attend a top university.
The New York Times recently reported about summer classes at one of the best high schools in the United States. New Trier High School is in Winnetka, Illinois. Almost six hundred students are in school this summer. Only twenty are repeating classes that they failed. The others are in difficult courses like physics and history.
The students say taking classes like these in the summer means that they can take even more difficult classes next year. They say this shows not only that they are serious about their studies but that they have experienced the most difficult high school program.
Another place with a lot of students in summer school is Palo Alto, California. The Mercury News reported that about twenty percent of the students in the city schools are in class this summer. That is more than two thousand teenagers.
A third are in classes they failed before. The others are taking subjects they do not have time for during the normal school year.
But they are not taking subjects like physics and history. The students in Palo Alto are in classes like creative writing, film studies, literature and cooking.
63. This passage mainly talks about ______.
A. summer classes in American schools
B. why American schools offer summer classes
C. the advantages of American summer school
D. experts’ anxiety(担忧)about American summer school
64. Which of the following is NOT the reason for the students’ attending summer classes in America?
A.Repeating a subject.
B.Completing a required subject ahead of time.
C.Improving their physical quality
D.Learning some special skills
65. What’s the biggest difference between the summer classes in New Trier High School and in Palo Alto?
A.There are more students attending classes that they failed before in Palo Alto.
B.Some students in Palo Alto learn some special skills instead of taking physics and history.
C.Some students in Palo Alto take some subjects so that they can join in sports or music programs later.
D.The students’ attitude towards studies in Palo Alto is worse than that in New Trier High School.
66. What can we infer from the passage?
A.American students in schools don’t have any pressure to attend top universities.
B.Summer school students don’t do the same amount of work as they do during the school year.
C. American students attend summer schools in order to relax themselves very much.
D. American students in high schools face great pressure to attend top universities.

A growing number of workers at Google Inc., Facebook Inc. and other employers are trading in their sit-down desks for standing ones, saying they feel more comfortable and energized. They also are motivated by medical reports saying that sitting for too long leads to increased health risks.
A standing desk sits high off the floor so a worker can either stand at it or sit on a high stool to use it. Officials at Palo Alto-based Facebook say a number of employees asked about standing desks after news articles were published about the health risks of sitting all day.
The stories cited medical studies that tied excessive sitting to increased obesity and other health problems because of factors including a drop in physical activity. A 2010 study by the American Cancer Society found that women who sat more than six hours a day were 37% more likely to die prematurely than women who sat for less than three hours, while the early-death rate for men was 18% higher. The American College of Cardiology released a study in January that found increased mortality (死亡率) among people who sat longer at home than those who didn't.
No one seems to compile statistics on the standing-desk trend. But anecdotal reports suggest Silicon Valley is embracing the movement.
Facebook officials say they have seen an upsurge in requests for standing desks to five to eight a week with a total of between 200 and 250 deployed (配置) at the company of more than 2,000 employees. Facebook also is trying out a treadmill station ─ where a worker can walk or run on a treadmill while tapping at a computer.
Google spokesman Jordan Newman said that 'many employees at Google opt for standing desks, and we offer them as part of our wellness program' though he said he didn't know the exact number.
Greg Hoy, 39 years old, asked for a standing desk shortly after joining Facebook seven months ago as a design recruiter. 'I don't get the 3 o'clock slump anymore,' he said. 'I feel active all day long.'
【小题1】The underlined word “motivated” in paragraph 1 can be replaced by .
| A．frightened | B．inspired | C．missed | D．discouraged |
| A．a drop in physical activity was the only reason why excessive sitting caused increased obesity. |
| B．women who sat longer were more likely to die prematurely according to a 2010 study by American College of Cardiology |
| C．according to the study, the early-death rate for men was 18% higher than that for women. |
| D．the mortality among people who didn’t sat long at home was lower than that among people who did. |
| A．is a computer that a worker can take along when he walks or runs |
| B．has been tried out by Facebook and now is very popular with other companies |
| C．is a place where workers can exercise while working. |
| D．is a treadmill on which workers can run or walk only after work |
| A．sitting for too long leads to increased health risks |
| B．standing desks have replaced sit-down ones in Facebook Inc. |
| C．more and more workers choose standing desks instead of sit-down ones |
| D．many employees at Google opt for standing desks |

A 33-year-old financial analyst in California recently quit his job to devote himself to an unpaid job teaching math on the Internet, and his lessons are reaching almost 100,000 people a month. Salman Khan’s voice is heard every day on the net — by tens of thousands of students around the world who are hungry for help learning math. He has posted 1,200 lessons on You Tube —lessons that appear on an electronic blackboard, which range from basic addition to advanced mathematics for science and finance. And they are free.
Khan lives in Silicon Valley, with his wife, a doctor, and their new baby. He got the idea for his “Khan Academy” four years ago, when he taught a young cousin how to convert kilograms to grams. With Khan’s help, the cousin got good at math, and Khan began a new career.
Now, Khan records his lessons himself, but he never goes on camera. “It feels like my voice in their head. You’re looking at it and it feels like someone’s over your shoulder talking in your ear, as opposed to someone at the blackboard, which is distant from you,” he said.
When Springfield High School in Palo Alto, California invited Khan to speak in person—he immediately connected to the students there.
The idea of short lessons that can be played over and over again attracted high school senior Bridget Meaney. She says she had trouble with math in the seventh grade. “I think the teachers are good, but they can’t teach at a speed that’s perfect for everyone,” she said. “I like the idea of learning something in class but then going back and pressing pause or rewind and actually getting a deeper understanding of it.”
Originally, Khan kept his lessons short because of YouTube restrictions. Now, he thinks short is better. “Education researchers now tell me that 10 minutes is how long someone can have a high level of concentration. And anything beyond that and your brain switches off,” he said.
For Khan, teaching math, science, and finance is just the beginning. He says he’s ready to expand his YouTube site to include other subjects as well.
1.What gave Khan the idea of teaching math online?
A．His success in helping his cousin learn math.
B．His discovery that many students found learning math difficult.
C．A suggestion made to him at a local high school.
D．His interest in Internet teaching.
2.Why does Khan never go on camera?
A．He’s too shy to show his face on camera.
B．It’s restricted by YouTube for education videos.
C．He wants to keep distance from the viewers.
D．He wants to create a more relaxed learning atmosphere.
3.From the passage, we know that ________.
A．Khan travels to many schools to promote his lessons
B．Khan plans to include more subjects in the future
C．Khan gives live math lessons every day for free
D．Khan set up the Khan Academy with his wife
4.Why does Bridget Meaney like Khan’s lessons?
A．Khan teaches seventh grade math better than her teacher.
B．The lessons can be watched repeatedly until fully understood.
C．She can perfectly follow the pace of Khan’s teaching.
D．She cannot concentrate when learning in class.
5.What does Khan mean by “short is better” in the 6th paragraph?
A．Keeping the lessons short can ensure better concentration.
B．YouTube recommends short lessons for its site.
C．Short lessons encourage students to return to the website.
D．Students enjoy short mathematics lessons more.
