What makes one person more intelligent than another? What makes one person a genius, like the brilliant Albert Einstein, and another person a fool? Are people born intelligent or stupid, or is intelligence
the result of where and how you live? These are very old questions and the answers to them are still not clear.
We know, however, that just being born with a good mind is not enough. In some ways, the mind is like a leg or an arm muscle. It needs exercise. Mental (done with the mind) exercise is particularly important for young children. Many child psychologists (心理学家) think that parents should play with their children more often and give them problems to think about . The children are then more likely to grow up bright and intelligent. If, on the other hand, children are left alone a great deal with nothing to do, they are more likely to become dull and unintelligent .
Parents should also be careful with what they say to young children. According to some psychologists, if parents are always telling a child that he or she is a fool or an idiot, then the child is more likely to keep doing silly and foolish things. So it is probably better for parents to say very positive (helpful) things to their children, such as “That was a very clever thing you did.” or “You are such a smart child.”

My teenage son Karl became withdrawn after his father died. As a single parent, I tried to do my best to talk to him. But the more I tried, the more he pulled away. When his report card arrived during his junior year, it said that he had been absent 95 times from classes and had six
falling grades for the year. At this rate he would never graduate. I sent him to the school adviser, and I even begged him. Nothing worked.
One night I felt so powerless that I got down on my knees and pleaded for help. "Please God, I can't do any thing more for nay son. I'm at the end of nay rope. I'm giving the whole thing up to you."
I was at work when I got a phone call. A man introduced himself as the headmaster. "I want to talk to you about Karl's absences." Before he could say another word,I choked up and all my disappointment and sadness over Karl came pouring out into the ears of this stranger. "I love my son but I just don't know what to do. I've tried everything to get Karl to go back to school and nothing has worked. It's out of nay hands. "For a moment there was silence on the other end of the line. The headmaster seriously said, "Thank you for your time", and hung up.
Karl's next report card showed a marked improvement in his grades. Finally, he even made the honor roll. In his fourth year, I attended a parent-teacher meeting with Karl. I noticed that his teachers were astonished at the way he had turned himself around. On our way home, he
said, "Mum, remember that call from the headmaster last year?" I nodded. "That was me. I thought I'd play a joke but when I heard what you said, it really hit me how much I was hurting you. That's when I knew I had to make you proud. 'There was silence on the other end of the line because

Say you are a 17th century construction worker who's worked long and hard to build a splendid tower for the dead wife of your emperor.
Now say that the emperor orders your fingertips cut off so you can never build another one. Yes, that is the Taj Mahal,one of the most famous buildings in the world. And the tale behind the construction is just as impressive as the building itself.
First, there's the emperor of northern India, Shah Jehan,also called the King of the World. In 1612,Shah Jehan married Mumtaz Mahal. Madly in love, they had 14 children over the next 20 years. But then sadness came. As Mumtaz was about to give birth to child'number 14, she said she had heard her unborn baby cry out. It was a sign of death. And as Mumtaz lay dying, she asked Jehan to build a lasting memorial to celebrate their love.
When the heartbroken Jehan appeared eight days after his wife's death, his people were shocked to see that his coal-black hair had turned snow-white.
Putting away his sadness, Jehan ordered his wife's dying wish carried out. More than 20,000 workers labored nearly 22 years to complete the construction. In 1653,Jehan placed Mumtaz's remains in the center under the building.
And then, son number five, Aurangzeb, murdered his brothers and took over the power from his aging father. Hehan lived the rest of his days-eight years, to be exact-imprisoned not far from the Taj Mahal. Jehan was only allowed to climb onto the top of his prison to see the timeless
treasure from a distance. But never again would he be allowed to visit it--until he was buried next to his wife.
Today 25,000 people visit the Taj Mahal each day. Though the reason for building the tower was a strange, sad story, those who see its breath-taking beauty are reminded of the happiness that inspired its construction.The first two paragraphs were written to show that

It was an early September day, cool and bright and just right for running, and I was in the first few miles of a lO-knownmile race over a course with a few high hills. Still, I felt energetic; despite the hills it was going to be a fine run.
Just ahead of me was Peggy Mimno, a teacher from Mount Kiseo, New York. She too was running easily, moving along at my speed. The pace felt comfortable, so I decided to stay where I was; why pay attention to pace when she was setting such a nice one? I'd overtake(追上) her later on when she tired.
So I ran behind her. The course headed north for miles, wandered west for a hilly mile, then turned south again along a winding road. The race was getting harder. We had four miles left and already it was beginning to be real work.
Peggy overtook a young runner. She seemed to know him, for they exchanged a few cheerful words as she passed him. Their exchange worried me. You don't chat during a race unless you feeling good, and Peggy plainly was.
Still, I was close enough to overtake her if she tired, so I didn't give up hope completely. We were getting nearer to a long, punishing hill now and it would be the test. We were a mile from the finish line, so whatever happened on the hill would almost determine who crossed it first.
As I moved up the hill, my attention wandered for a few minutes. When I looked up, Peggy was moving away--first five yards, then ten, then more. Finally it was clear that there was no help of catching her. She beat me soundly.
There is an important lesson in that race. Women are thought to be weaker, slower and not nearly as skilled in sport. Yet as Peggy Mimno so clearly showed, the similarities between men and women runners are more important than differences. I have run with a number of women, and I can say it is often hard work.What did the writer think of the race in the beginning?
| A．It would be hard work. |
| B．It would be an easy race. |
| C．It would be a test of his strength. |
| D．It would be a good learning experience. |
What worried the writer when Peggy greeted the young runner?
| A．Peggy overtook the young runner. |
| B．Peggy was running energetically. |
| C．Peggy was laughing as the writer. |
| D．Peggy paid no attention to the writer. |
By saying "a long, punishing hill" (paragraph 5 ), the writer implies that _____________ .
| A．Peggy would fail to reach the hilltop |
| B．men are more skilled at climbing hills |
| C．overtaking Peggy would be easy |
| D．climbing the hill would be a demanding task |
What lesson does the writer learn from the race?
| A．Women are as good as men in sport. |
| B．Women are better at climbing hills. |
| C．He should have more training in a cross-country race. |
| D．He should set a quicker pace at the beginning of a race. |
We might like to think we're not influenced by other people, but a new study into the group-buying mechanisms（机制） - like those used on coupon（优惠券） sites such as Groupon and LivingSocial - reveals that telling buyers who come later to the offer how many have already signed up increases the number of purchasers.
Researchers at the University of Toronto's Rotman School of Management wanted to understand why group buying sites that have entered the market recently have enjoyed greater success than those operating a decade ago, such as Mercata and MobShop.
Earlier attempts typically left potential buyers waiting for days before confirming whether or not they had got the offer they had signed up for.
“We think one of the reasons group-buying has been successful recently is because of the short time horizon,” says Rotman Professor Ming Hu, who co-wrote the study with Professor Mengze Shi and PhD student Jiahua Wu. “It allows for a herding effect.”
Another reason is the use of an information structure that discloses to later arrivals how many have already signed onto the deal.
Researchers looked at two ways of designing the purchasing mechanism for a group buy:a simultaneous mechanism, where no one knows how many buyers have come before them, and asequential（连续的） mechanism, where a second group of buyers has the advantage of knowing the size of the first group.
The researchers' analytical（分析的） model shows the most successful mechanism is the sequential one because it eliminates uncertainty for those coming later to the deal, and improves the confidence of those who sign on early, as they're able to track the numbers of those who come after them.
“That boosts confidence,” says Professor Hu, who teaches operations management. Deals for "luxury" services, versus everyday items, work better in a group buy scenario（方案） because they offer consumers a greater benefit.It can be learned from the text that ______.
| A．the short time horizon is the reason why group-buying has been successful. |
| B．a simultaneous mechanism is where a group of buyers has the advantage of knowing how many people have signed up. |
| C．a sequential mechanism allows a herding effect which boosts the confidence of the buyers. |
| D．researchers at the University of Toronto's Rotman School of Management carried out an experiment about why group buying sites entered the market successfully, such as Mercata and MobShop. |
The underlined word “eliminates” in paragraph 7 probably means“______”.
| A．to become or to make something greater in amount, number, value |
| B．to remove or get rid of something |
| C．to deliberately not include something in what you are doing or considering |
| D．to make something known to somebody |
What can be the best title for the passage?
| A．Secret for marketing success – boosting confidence. |
| B．Secret for group-buying mechanism—herding effect. |
| C．Comparison between a simultaneous mechanism and a sequential mechanism. |
| D．What others do influences our decisions. |
Mobile phones are an important business tool for farmers in rural areas. But they also put a valuable educational tool in their hands.
The University of Illinois in the United States has a project called SAWBO—Scientific Animations Without Borders. It produces educational videos that can be downloaded to cell phones. The goal is to help people in developing countries improve their lives.
One video shows farmers how to make a natural insecticide from neem seeds to prevent insect damage to crops. The process starts with sorting and drying the neem fruits. Then let the fruit dry in the sun for about three or four days, until they become brown. Using a mortar(碾槌) and stick, the fruits are slightly pounded to remove the shells from the fruits without breaking the seed inside.
The videos use computer animation(动画). Some of the animated characters are a little funny looking-like a farmer with a long nose. But the subjects are serious, including a health video on preventing cholera(霍乱). Team member Francisco Seufferheld says the information in the videos is meant to be quickly understood. He says, “The information is digested in such a way that in two minutes, we can transmit a complex idea.”
The researchers tested the seven-minute video on seven mobile phones. They wanted to see if people would share the video using Bluetooth wireless technology. With Bluetooth, files can be passed to a nearby phone even if neither phone is connected to the Internet. As a result, in one month, the video had spread to one hundred eighteen people in fifty different villages. “This is just incredible impact,” said Francisco Seufferheld.
The team has made a few videos so far. These are available in a total of eighty languages, dialects and accents. Professor Barry Pittendrigh says there are plans for more videos later this year. What is the text mainly about?
| A．A best-selling mobile phone |
| B．A valuable educational project for farmers |
| C．United States support for developing countries |
| D．A new type of scientist –farmer relationship |
The SAWBO program is introduced in order to ____.
| A．raise farmers’ standard of living |
| B．do some research on mobile phones |
| C．develop farmers’ practical skills |
| D．help farmers prevent insect damage to corps |
The biggest advantage of the program is that it______.
| A．includes health video on preventing cholera |
| B．can be passed to farmers using Bluetooth technology |
| C．can be used to sort and dry the neem fruits |
| D．is easy for farmers to understand |
