Many facts suggest that children are overweight and the situation is getting worse, according to the doctors. I feel there are a number of reasons for this.
Some people blame the fact that we are surrounded by shops selling unhealthy, fatty foods, such as fried chicken and ice cream, at low prices. This has turned out a whole generation of grown-ups who seldom cook a meal for themselves. If there were fewer of these restaurants, then probably children would buy less take-away food.
There is another argument that blames parents for allowing their children to become overweight. I agree with this, because good eating habits begin early in life, long before children start to visit fast food shops. If children are given fried chicken and chocolate rather than healthy food, or are always allowed to choose what they eat, they will go for sweet and salty foods every time, and this will carry on throughout their lives.
There is a third reason for this situation. Children these days take very little exercise. They do not walk to school. When they get home, they sit in front of the television or their computers and play computer games. Not only is this an unhealthy pastime (消遣), it also gives them time to eat more unhealthy food. What they need is to go outside and play active games or sports.
The above are the main reasons for this problem, and therefore we have to encourage young people to be more active, as well as steering them away from fast food shops and bad eating habits.
According to the text, what kind of children may eat more unhealthy food?
A. Those who often take exercise.
B. Those who often watch television.
C. Those who often have meals at home.
D. Those who often walk to school.

The main purpose of the text is to _________.
A. tell a story B. provide facts
C. give advice D. compare opinions
If you do not use your arm or your legs for some time, they become weak; when you start using them again, they slowly become strong again. Everybody knows that. Yet many people do not seem to know that memory works in the same way. When someone says that he has a good memory, he really means that he keeps his memory in practice by using it. When someone else says that his memory（记忆力） is poor, he really means that he does not give it enough chance to become strong. If a friend says that his arms and legs are weak, we know that it is his own fault(过错). But if he tells us that he has a poor memory, many of us think that his parents are to blame(受责备), and few of us know that it is just his own fault. Have you ever found that some people can’t read or write but usually they have better memories? This is because they cannot read or write and they have to remember things they cannot write down in a little notebook. They have to remember days, names, songs and stories; so their memory is the whole time being exercised. So if you want to have a good memory, learn from the people: Practice remembering.

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.
London is the capital of Britain. It is located in the southeast plain of England. The Thames River goes through this city.

In only two decades Asian Americans have become the fastest-growing US minority．As their children began moving up through the nation’s schools，it became clear that a new kind of culture was coming out．Their achievements are made in the nation’s best universities，where mathematics，science and engineering departments have taken on a decidedly Asian character.This special liking for mathematics and science is partly explained by the fact that Asian-American students who began their education abroad arrived in the U.S. with a solid grounding in mathematics but little or no knowledge of English.They are also influenced by the promise of a good job after college．Asians feel there will be less unfair treatment in areas like mathematics and science because they will be judged more objectively(客观)．And the money spent on education is more immediately returned in something like engineering than with an arts degree．
Most Asian-American students owe their success to the influence of parents who are determined that their children should take full advantage of what the American educational system has to offer.An effective measure of parental attention is homework. Asian parents spend more time with their children than American parents do，and it helps．Many researchers also believe there is something in Asian culture，such as family value，the importance of education and so on that lead to their success.
Both explanations for academic success worry Asian Americans because of fears that they could cause the native Americans’unhappiness．Many can remember when Chinese,Japanese and Filipino immigrants(移民)were unequally treated because of social separation．Indeed，it was not until 1952 that laws were laid down giving all Asian immigrants the right to citizenship.
【小题1】Few Asian-American students major in human sciences mainly because .
| A．they are afraid they might meet with unfair judgement in these areas |

| D．their English is not good enough |
| A．people majoring in engineering are respected |
| B．people with an arts degree are looked down upon |
| C．they can’t find a job with an arts degree |
| D．they can earn more money after graduation |
| A．are afraid that their academic successes take on a strong Asian character |
| B．still worry about unfair treatment in society |
| C．generally feel it a shame to have to depend on their parents |
| D．feel they are mistreated because of limited knowledge of English |
| A．Asian culture and the American educational system |
| B．Asian culture and a solid base in basic mathematics |
| C．hard work and parental help |
| D．hard work and a limited knowledge of English |
