Skateboarding has become one of several non-traditional activities that PE teachers around America are introducing to inspire kids to exercise regularly. Some PE classes feature in-line（滾輪） skating, yoga, and even rock climbing. Experts have called those types of activities “the new PE”.
Such activities are part of a larger effort to help kids develop lifelong fitness habits and to keep them from becoming overweight. Now, 9 million U.S. children and teens are overweight. Obesity (肥胖) can lead to health problems such as diabetes and heart disease later in life.
"Our children and youth are becoming unhealthy and obese," says Johnson. "Skateboarding is a great activity that keeps kids doing physical movement and gives them new skills and interest."
Some schools don't allow skateboarding because they say it is dangerous. Tim, however, argues that regular practice eliminates a great deal of the danger. "We teach students how to do it and how to do it safely," he says.
Some people say skateboarding teaches life lessons. “Skateboarding teaches kids to believe that if they stick with something they will finally succeed. ”says education expert Richard Savor from College in Portland.
Skateboarding inspires kids not to give up in learning difficult skills. "It's natural for kids to want to learn and get better at things," adds Tim. "When it comes to skateboarding, they'll try a trick hundreds of times before they succeed." That same effort could be made in schoolwork.
Eric Brown agrees that skateboarding requires kids to stop saying a task is too hard for them. "A baby will attempt to walk 600 to 900 times before he or she is successful," says Eric, "We tell students that they shouldn't say 'I can't do it' unless they've tried 600 to 900 times.
72. Skateboarding is introduced into American schools to ______________.
A. encourage students to compete bravely in competition  
B. teach students how to deal with risk.
C. prevent students suffering from heart disease later in life.
D. help students form the habit of doing sports
73. The underlined word "eliminates" in Paragraph 4 probably means ______________.
A. reduces.         B. increases         C. adds        D. brings
74. What life lesson do kids learn from skateboarding?
A. To succeed in life you have to learn skateboarding.
B. You will succeed in life if you don't give up.
C. Only after failing 600 to 900 times can you succeed.
D. There is no hard work after learning skateboarding well.
75. What would be the best title for the passage?
A. The dangerous PE            B. Skills of skateboarding.  C. The new PE.      D. The change of PE.

As any homemaker who has tried to keep order at the dinner table knows, there is far more to a family meal than food. Sociologist Michael Lewis has been studying 50 families to find out just how much more.
Lewis and his co-workers carried out their study by videotaping (錄像) the families while they ate ordinary meals in their own homes. They found that parents with small families talk actively with each other and their children. But as the number of children gets larger, conversation gives way to the parents’ efforts to control the loud noise they make. That can have an important effect on the children. “In general the more question-asking the parents do, the higher the children’s IQ scores,” Lewis says. “And the more children there are, the less question-asking there is.”
The study also provides an explanation for why middle children often seem to have a harder time in life than their siblings (兄弟姐妹). Lewis found that in families with three or four children, dinner conversation is likely to center on the oldest child, who has the most to talk about, and the youngest, who needs the most attention. “Middle children are invisible,” says Lewis. “When you see someone get up from the table and walk around during dinner, chances are it’s the middle child.” There is, however, one thing that stops all conversation and prevents anyone from having attention: “When the TV is on,” Lewis says, “dinner is a non-event.”
66．The writer’s purpose in writing the text is to _________.
A．show the relationship between parents and children
B．teach parents ways to keep order at the dinner table
C．report on the findings of a study
D．give information about family problems
67．Parents with large families ask fewer questions at dinner because ____________.
A．they are busy serving food to their children
B．they are busy keeping order at the dinner table
C．they have to pay more attention to younger children
D．they are tired out having prepared food for the whole family
68．By saying “Middle children are invisible” in Paragraph 3, Lewis means that middle children _________.
A．have to help their parents to serve dinner
B．get the least attention from the family
C．a(chǎn)re often kept away from the dinner table
D．find it hard to keep up with other children
69．Lewis’ research provides an answer to the question _________.
A．why TV is important in family life
B．why parents should keep good order
C．why children in small families seem to be quieter
D．why middle children seem to have more difficulties in life
70．Which of the following statements would the writer agree to?
A．It is important to have the right food for children.
B．It is a good idea to have the TV on during dinner.
C．Parents should talk to each of their children frequently.
D．Elder children should help the younger ones at dinner

         All of us eat every day, but most of us don’t understand nutrition. We often make mistakes in talking about good diet.
For example, many people think that foods such as rice, bread and potatoes will make one grow fat. In fact, these foods are very good to one’s health. They are good sources of many vitamins. And in comparison with steak and beef, they contain less amount of calories.
Some people don’t like canned(罐裝的) or frozen vegetables, because they think fresh vegetables cooked at home are always better. This is again wrong. In fact, whether the vegetables are good or not depends more on how they are prepared. Overcooking, for example, destroys good qualities of vegetables. Vegetables cooked in too much water can lose a large amount of vitamins.
It is widely believed extra vitamins provide more energy. But taking more than the body needs doesn’t make it function better.
It is also wrong to say that vegetables grown in poor, worn-out soil are lower in vitamins than vegetables grown in rich soil. The vitamins in our foods are in the plants themselves. They don’t come from the soil. However, the minerals(礦物質(zhì)) in a plant depend on the minerals in the soil.
In short, there are many false ideas about nutrition. We need to correct them.
46. This passage is mainly about_______.
A. nutrition                B. vitamins                C. vegetables            D. health
47. Rice, bread and potatoes do good to people’s health mainly because_______.
A. they make people fat                              B. there are lot of vitamins in them
C. they contain less amount of calories compared with steak and beef.
D. both B and C.
48. Why don’t some people like canned or frozen vegetables? Because______.
A. they think fresh vegetables contain less vitamins
B. they think fresh vegetables contain more vitamins than the canned or frozen ones
C. they don’t think the canned or frozen vegetables are fresh
D. they don’t think the canned or frozen vegetables taste as good as the fresh ones
49. Which of the following is true according to the passage?
A. Many people know almost everything about nutrition.
B. Food such as rice, bread and potatoes make people fat.
C. vegetables grown in poor worn-out soil may have the same amount of vitamins as vegetables grown in rich soil.
D. extra vitamins provide less energy.
50. The point of the passage is that______.
A. the minerals in a plant depend on the minerals in the soil
B. people make mistakes when talking about good diet

    The angry locals of an English village blocked the driver of a Google Street View car who was
filming the neighborhood, saying they feared he world encourage thieves, a report said Friday.
One local, Paul Jacobs, told the BBC he had warned his neighbors after spotting the car from
his window in Broughton, Buckinghamshire, southern England, on Wednesday.
“I don’t have a problem with Google wanting to promote villages. What I have a problem with
is the invasion （侵犯）of privacy, taking pictures directly into the home,” Jacobs said.
“We’ve already had three homes broken into locally in the past six weeks. If our houses are
made noticeable all over Google, it’s an invitation for more criminals to strike. I was determined to
make a stand, so I called the police.”
After his call, a police car arrived in Broughton in response to an argument between a crowd of people and a Google Street View contractor.
“They felt his presence was a threat to their privacy. When police arrived at the scene, the car had moved on,” explained a spokeswoman for Thames Valley Police.
The Google Street View project, set up last month in Britain, aims to provide detailed 360-degree views online of streets all over Britain.
The project has already been strongly criticized by associations like Privacy International, a pressure group which has launched legal action against the IT company.
Google is confident that their new mapping project is within the law.
“Before launching Street View we sought the guidance and approval of the Information Commissioner’s Office. The ICO has repeatedly made clear that it believes that Street View includes the safeguards necessary to protect people’s privacy,” a Google spokesman said.
“The Metropolitan Police （in London） told us they saw no significant security risk, that thieves are likely to make use of the opportunities, and that mapping products can be useful in solving and mapping crime in an area.”
He added: “Engaged in new projects, we sometimes meet unexpected challenges, and Street View has been no exception.”
41．When the police car arrived at the village,           .
A．the villagers were angrily arguing with the Google car driver.
B．the map car was stopped from leaving the village.
C．The map car had stopped its working and gone on its way.
D．The map car was surrounded by the angry villagers.
42．The underlined phrase “make a stand” in Paragraph 4 means       .
A．stand there all the time whole waiting for the police
B．show full support to Google’s filming the neighborhood
C．a(chǎn)ttempt to defend locals by stopping Google’s filming the neighborhood
D．stand in the way to stop the car moving on
43．Which of the following sentences is TRUE?
A．Google’s mapping project has not been officially approved.
B．Three homes had been visited by thieves with the help of Google pictures.
C．The police rushed to stop a fight between locals and Google contractors.
D．It was not the first time that the Google map project had been criticized.
44．What’s the best title for the passage?
A．Google’s Mapping Project Promotes the Neighobrohood.
B．Angry British Villagers Stop Google Maps Car.
C．Google Goes On With its Plan to Film the Streets.
D．New Project Meets Challenges Again.

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固定不動(dòng)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.
56. The recent survey shows that _________.
A. watching TV can cause all kinds of diseases for children
B. TV sets have played an important part in our daily lives
C. Watching TV over 2 hours a day early in life can cause attention problems later in adolescence
D. watching TV has side effects on children’s future
57. People used to think that _________.
A. watching TV more than 2 hours every day did good to children’s health
B. the sedentary habit of TV watching among children could easily lead to obesity and diabetes
C. the children wasn’t patient with their homework because of watching TV too much
D. it was very important for children to watching TV early in life
58. The underlined word “Hence” means _________.
A. In that case    B. And yet    C. On the contrary    D. For this reason
59. In Landhuis’ opinion, _________.
A. attention problems caused by watching TV during childhood may be hard to get rid of
B. how to develop children’s attention problems is a lasting problem
C. the key of settling attention problems is not watching TV too much
D. there shouldn’t have many food products ads on children's television shows

The first thing to remember about homework is that it needs to be done as soon as you get home from school. Since many parents do not give doses to help you sleep at night, the homework MUST be done first. If you have after-school activities, the homework should be done as soon as you get home. It is fine to allow for a snack break and also to allow for stretching breaks. Every kid of you really needs these little breaks.
Also, you should remember that it is your responsibility to do your homework. Next time you tend to depend on Mom and Dad for a roadmap, please try to struggle with it first, because it is good for you.
When you have questions, especially something about a science or a math problem, don’t always turn to your teacher! It is a good idea to struggle with them first and try to work them out. Sometimes, if this doesn’t work, look at the materials in the back of the book. They may guide you to pages and and understanding everything completely.
At last, while doing homework, don’t be looking away but continue working. Setting time limits often helps with this. Different ages decide different fair amounts of time. 10-15minutes is good for a child that’s age 6-8. A time of 20-30 minutes is about right for a child aged 9-12. Kids can achieve 30-45 minute intervals of study at age 13-15. This, of course, depends on your abilities to concentrate and stay on task.
60. The passage mainly tells children ________.
A. to do their homework quickly and properly
B. to limit their time of doing homework
C. not to turn to teachers when doing homework
D. not to look away while doing homework
61 Which of the following may have the same meaning as “struggle with them”?
A. fight against them         B. study them carefully
C. break away from them      D. show great interest in them
62. If you are a girl aged 14, the proper length of the homework time should be________.
A. 14 minutes    B. 25 minutes    C. 35 minutes     D. 50 minutes
63. The author seems to think ________.
A. children should finish their homework at school
B. parents had better help children with their homework
C. doing homework all alone is more important
D. homework in science needs more time
