1. If you use it often and in the right ways, you will become a more skilled thinker and your ability to focus will increase. But if you never use your brain, or abuse it with harmful chemicals, your ability to think and learn will decrease. Here are some simple ways that may help you.

Don’t you feel drained(劳累) after a couple of hours of watching TV? Your eyes are sore and tired of being focused on the light box for so long. When you feel like relaxing, try reading a book instead. If you’re too tired, listen to some music. When you’re with your friends or family, leave the tube off and have a conversation. All of these things use your mind more than television and allow you to relax.

Exercise.

I used to think that I’d learn more by not exercising and using the time to read a book instead. 3. It improves productivity(生产力) during the time afterwards. Using your body clears your head and creates a wave of energy. Afterwards, you can concentrate(专注) more easily.

Read challenging books.

If you want to improve your thinking and writing ability, you should read books that make you focus. Reading a classic novel can change your view of the world and will make you think in more elegant English. 4. Re-read it when necessary, and you’ll soon grow accustomed(习惯) to the author’s style.

Early to bed, early to rise.

5. You’ll be the most energetic if you go to bed early and don’t sleep for more than 8 hours. In my experience the early morning hours are the most productive. If you have the opportunity, take a 10-20 minute nap(小憩) when you are hit with a wave of drowsiness(睡意).

A. Take a time to reflect.

B. Reduce television watching.

C. Spending some time alone will be helpful.

D. Your brain needs exercise just like a muscle (肌肉).

E. Don’t be afraid to look up a word if you don’t know it.

F. Nothing makes it harder to concentrate than sleep loss.

G. But I realized that time spent exercising always leads to greater learning.

A 16-year-old South Dakota boy who became lost while hunting and spent 16 hours alone in the Black Hills National Forest says he was scared but still managed to make a survival plan.

Austin DuVall, of Rapid City, became lost on Nov.3 while hunting with his father. He ran after a deer, and soon found himself alone. “I ran after a deer, but I didn’t get it,” he said. “Then I was really lost.”

He had only his hunting rifle(步枪) and the clothes he was wearing. He had no food or water and had nothing that could help him find his way to safety. “I knew that no one could hear me. I decided to just sleep and get up in the morning and find safety,” he said.

Austin climbed up on a rock and slept through the night. Then he awoke and relied on skills he learned in a hunter safety course. He followed a stream to an occupied cabin. The couple there called his parents and cooked him a breakfast. “ It’s probably one meal I’ll never forget for the rest of my life,” he said.

After DuVall’s disappearance, a lot of emergency officials and more than 100 volunteers went searching for him. “He wasn’t sitting there waiting for someone to come and find him,” said his father, Steve DuVall. “We didn’t find him; he found himself.”

Mike Kintigh, regional supervisor for the Game, Fish & Parks Department, said one or two hunters will go missing each year, but rarely for more than 24 hours. “We’re a little bit unique in the Black Hills as it’s hard to get lost for a very long time. That’s because we’ve got so many roads here compared to the Rocky Mountains,” Kintigh said. “You can certainly spend a very uncomfortable night in the woods like Austin did.”

1.After Austin realized he lost his way, he ___.

A．was very nervous but excited

B．cried aloud for help

C．tried to find a safe place

D．decided to sleep in the wild

2. Who saved Austin according to his father?

A．The couple in the cabin.

B．Emergency officials.

C．Volunteers.

D．Himself.

3.From what Mike Kintigh said, we learn that _______.

A．if someone gets lost in the Rocky Mountains, it is hard to find a way out

B．too many people go missing in the Black Hills every year

C．the rescue team is skillful enough to find the lost people in less than 24 hours

D．people who are lost in the Black Hills have to spend a night in the woods

Dear Customers,

I love slipping (滑落) into a comfortable chair for a long read—as I relax into the chair, I also relax into the author’s words, stories and ideas. The physical book is so elegant that it disappears into the background, and what remains is the author’s world.

Today, we at Amazon are excited to announce Mindle, a wireless, portable reading device with instant access to more than 90,000 books, magazines and newspapers.

We’ve been working on Mindle for more than three years. Our top design objective was for Mindle to disappear in your hands—to get out of the way—so you can enjoy your reading. We also wanted to go beyond the physical book. Mindle is wireless, so whether you’re lying in bed or riding a train, you can think of a book, and have it in less than 60 seconds. No computer is needed—you do your reading directly from the device.

We chose the same wireless technology used in advanced mobile phones. But unlike mobile phones, there are no monthly wireless bills, no service or data plans, and no yearly contracts. There is no software to install (安装，设置)。 We want you to get lost in your reading and not in the technology.

Mindle uses a new kind of display called electronic paper. Sharp and natural with no strong light, reading on Mindle is nothing like reading from a computer screen. Mindle weighs only 10.3 ounces—less than paperback—but can carry two hundred books.

Enjoy learning about Mindle and many thanks!

Jeff Bezos Founder & CEO

A political scientist from Indiana University whose work exploring how people come together to protect their collective （共有的）resources may provide important clues in the fight against elimate change has become the first woman to win the Nobel prize for economics.

Elinor Ostrom, 76, shares the award with fellow American academic Oliver E. Williamson, 77. The Royal Swedish Academy of Sciences announced to the world the pair had been chosen to win the 40th prize in economic sciences.

For Ostrom, the award came, as she showed, as a “big surprise”. To rise to the summit of her area of learning has been an big journey, as she has had to struggle against her own weaknesses and the impediments （妨碍）of the system. At school in Los Angeles she suffered from stuttering（口吃）. She also faced the hurdles （障碍） common to most women of her generation entering the sciences--she was discouraged from taking a PhD when she applied for graduate school.

Her field of study has been striking for how cross-disciplinary （交叉训练的）it is. Early on she gained a reputation for bringing economics, political science and sociology together.

What interests her is how common property can be managed successfully through groups in society. One of the first subjects that interested her was management of water resources.

The findings of her research have been striking, because they have challenged the traditional idea that common property is poorly managed unless it is either regulated by government or privatized. She has shown how individuals can work together and form collectives that protect the resource at hand.

“A lot of people are waiting for more international co-operation to solve global warming,” said Ostrom, “It is important that there is international agreement, but we can take steps at family level community level, and national level … There are many steps that can be taken. That will not solve it on their own but continuously will make a big difference.”

1. Why was Ostrom not advised to take a PhD?

A. Because she was a stutter who didn’t speak fluently.

B. Because she was a woman who was prejudiced then.

C. Because she was as common as other women in science.

D. Because she didn’t receive a degree of master yet.

2. Which of the following statements may Ostrom agree to?

A. Only government can make full use of common property.

B. Private enterprise can control individual behavior.

C. Different people should work together to protect the resources.

D. Individuals play a minor role in fighting climate change.

3. Ostrom was awarded the Nobel Prize for economics because _______.

A. she brought economics and political science into sociology

B. she predicted the breakout of the global financial crisis

C. she worked on the relationship between individuals and government

D. she put forward a new theory to help fight against climate change

4. The passage mainly tells us that ________.

A. the Nobel Prize for economics was first won by a woman

B. Elinor Ostrom’s work may help fight poverty

C. the first woman won the Nobel Prize in America

D. the Nobel Prize for economics is shared this year
