金博士一点全通系列答案Eighth-grader Victoria Bills is talking about money with her classmates. She is worried that a company’s stock (股票) price could fall. It may be an unusual topic of conversation for a 13-year-old. But at Bills’ school in Chicago, US, you hear it all the time.
The Chicago school’s 420 students learn about economic(经济学). They also get a chance to make money. Each 1st grade and 5th grade, students learn the basics of economics and investing(投资).
Then in 6th grade, they put what they’ve learned to work. Students join a junior group that manages the $20,000. The group, made up of 12 to 14 students, decides which stocks to buy.
After graduating, students pass on $20,000 to the next 1st grade class. They keep half of the rest of the money; the other half goes toward improving the school. They can choose to put their money in a college-savings program or take the cash.
In 2007, Bills suggested that her class buy the stock of the Apple computer company. This was just before the iPhone came out. “We bought stock just at the right time,” she says. The kids bought Google stock as it reached $400 a share. It is now worth over $500. “It was a good buy,” says Myles Gate, 13. He hopes to be a banker one day.
The school’s two graduating classes of 2005 and 2006 have each earned about $10,000 in profits(利润).

We always regard dogs as man’s best friends. But what about cats?
Cats can also do us a favor sometimes.
Here is a comparison of the two animals.
A Friend Helps You When You’re Sick
| Dogs | When Catherine lay down on the sofa, Pepe stared(盯) into her eyes and kept sniffing(嗅). After being pushed away, he suddenly jumped onto her chest. That’s when Catherine felt a pain that made her visit a doctor, and a fast-growing cancer was found. Months later, however, Pepe started staring and sniffing again. It seemed strange, but sure enough, Catherine’s cancer had spread. |
| Cats | Alana immediately finds a chair when Tee sits and stares directly into her face. That’s because Tee is warning her that she is about to faint(昏倒), which can happen as often as three times a day. But Alana won’t get hurt if she sits down. Not only does Tee warn Alana, but also her husband. Then the cat stays with Alana until she recovers. |
| Dogs | Ryan fell into the water by accident. The river was full of ice, and Ryan was very cold and his body temperature was dropping dangerously low. Luckily, he was found by Chelsea, who was playing with her dog, Zion. “Zion knew the boy was in trouble,” says Chelsea. “Ryan grabbed onto the dog’s collar, and Zion just turned around and came back to the bank.” |
| Cats | Bernice says: “I was sleeping in my bedroom, and then I was woken by Joey screaming and running”. Then she found smoke around her. With Joey helping her, she managed to get out of the door. “I found him in a mailbox when he was young and now I feel very lucky. Without him, I’d have probably died in the smoke.” |

We go to school every day to become a better person. So how can we become powerful and start changes in our own life? Perhaps we can get tips from the US First Lady Michelle Obama. During her visit to China, from March 20–26, Mrs Obama shared her views on education with students.
The first lady encouraged Chinese students to aim high and get a good education. In Chengdu No 7 High School, she told students that having poor roots doesn’t matter as long as you have perseverance (毅力).
Mrs Obama said her family was not rich. Like many Chinese students, her parents had big dreams for her. She felt the weight of her parents’ sacrifices (牺牲) on her shoulders and worked hard to make them proud.
Persevering was not easy, though. Sometimes she had to wake up at 4:30 a.m. and study late into the night. “But whenever I got tired or discouraged… I would remember something my mother always told me. She said: ‘A good education is something that no one can take away from you.’”
Mrs Obama also encourages Chinese students to study abroad. “As the Chinese saying goes: It is better to travel 10,000 miles than to read 10,000 books,” she said. It’s not enough to get good grades in school. It’s also important to have real experience with languages, cultures and societies different from your own, she noted.
Studying abroad could also gain future international relations. It could help young people from different countries work together to deal with problems such as climate change, Mrs Obama said.

I was not having a happy holiday. My family had decided to go back to the countryside in New Hampshire, US, again. But I found it boring. What made the holiday even worse was that I had to sleep in the same bed as my brother. But I was wrong. This trip was the best holiday I have ever had. During the holiday, I met a very special friend.
While I was walking in the countryside, I saw a man carrying a small brown bag. Wearing white clothes, the man looked like a ghost. As he looked at me, I felt frightened. I wanted to run away when the man spoke to me. “Hello. Beautiful day, isn’t it?” he said. The man talked a lot. I wasn’t listening very carefully because I was looking at his little bag. I wanted to see what was inside it!
He saw me looking at the bag and he asked me if I would like to see. Out came a lively, beautiful puppy. The brown puppy was small and only about two months old. The man then asked me, “Would you like to keep this puppy?” I had always wanted a puppy and now I had the chance. I thanked him, took the puppy and ran home. For the rest of that summer, I played with him all the time. And after the trip, I took him home. The puppy is now loved by all my family. He is a friend to both my brother and me, a warm little ball of happiness in our lives.
I’ve always wanted to thank the man because he changed my life. His gift has given me years of pleasure. And I never have boring family holidays anymore.

Saying no starts small
“All right then — just one more piece...” Words every girl has said when they are faced with the delicious cheesecake. Of course, many of us know we may eat the whole thing in the end.
It isn’t just girls. Most of us find it hard to say “no” to something attractive. However, scientists now say that willpower is very important to success and a happy life.
Scientists in different countries have been studying the effects of willpower on people’s lives for a long time. The results are similar, according to an article on February 7 in the Guardian, a famous British newspaper.
In one experiment, scientists told young children that they could either have a marshmallow (圆形软糖) now, or two marshmallows in 15 minutes. Waiting obviously needed more willpower. Scientists then continued studying the children as they grew up. They wanted to see if some children always had stronger willpower. They also wanted to see how having stronger willpower affected their lives.
Years later, scientists found that the children who had waited for two marshmallows were all healthier, happier and richer adults. Oppositely, the children who had shown weaker willpower at that young age were more likely to be in low-paid jobs, to be overweight, to have social problems.
But there is hope, Roy F Baumeister, an American social psychology(心理学) professor (教授) told the Guardian. Baumeister says we can train our willpower just like we train our muscles（肌肉）. Even a little practice can strengthen（加强） our overall self-control if we do it regularly.
You could start by making yourself stand up straight, speaking in complete sentences, or using a computer mouse with the other hand. Scientists have found that people who manage to change little habits often perform much better in laboratory willpower tests.
Like muscles, willpower can “get tired”. Don’t try to do too many things at the same time, or when you don’t have enough energy, for example when you are ill. If you already feel tired, you can try to recharge(恢复) your willpower with a good night’s sleep and by eating well.
【小题1】The example of a girl eating cheesecake is used to
| A．prove that girls have weak willpower |

| B．It showed that willpower is the most important to success and a happy life. |
| C．The children who chose to wait were more likely to be successful in their lives. |
| D．The children who chose only one marshmallow at first had stronger willpower. |
| A．You should have a goal every day. |
| B．Good rest and proper diet can help. |
| C．Willpower needs to be exercised regularly. |
| D．Keep willpower from being used too much. |
| A．How willpower and muscles are similar and how they can be trained. |
| B．How willpower affects people’s lives and how it is similar to muscles. |
| C．How willpower is important to success and how we can make it stronger. |
| D．How willpower is connected with success and how they affect each other |
