Sorry to say, our brains pastorally start slowing down at the cruelly young age of 30. It used to be thought that this couldn’t be helped，but new studies show that people of any age can train their brains to work faster.“Your brain is a learning machine,” says University of California scientist Dr. Michael Merzenich. Given the right tools, we can train our brains to act like they did when we were younger. All that’s required is the practice designed just for the purpose: a few exercises for the mind.
Merzenich has developed a computer-based training method to speed up the process (过程) in which the brain deals with information (positscience com ). Since much of the data we receive comes through speech, the Brain Fitness Program works with language mad hearing to better speed and accuracy (准确性).
Over the course of training, the program starts asking you to distinguish (辨别)sounds (between “dog” and “bog”, for example) at an increasingly faster speed. It’s a bit like tennis instructor, says Merzenich, hitting balk at you faster and faster to keep you challenged(受到挑战). You may start out slow, but before long you’re pretty quick.
The biggest finding in brain research in the last ten years is that the brain at any age is highly plastic. If you ask your blain to learn，it will learn. And it may even speed up while in the process.
To keep your brain young and plastic you can do one of a million new activities that challenge and excite you：playing table tennis or bridge，doing crossword puzzles，learning a language....“When it comes to preventing ageing，you really do use it or lose it’s，”says Barbara Sahakian, professor at Cambridge University.

Nothing can spoil a vacation quicker than losing your money or credit cards. A few simple steps before you head out of the door can help protect your cash, card and personal information while you’re traveling.
Paul Stephens, a policy analyst San Diego, notes that people spend a lot of time planning their trips, from buying guidebooks to finding just the right beach outfits（装备）. “But their eyes glaze（呆滞）over when the subject of keeping money s
afe comes up,” he said.
“Why not take a few minutes to do something that could probably save your vacation?” Stephens asked．“In most cases, they can go on your to-do list with ‘buy travel bags’ and everything else,” he added.
The top recommendation is to clean your wallet. Remove unnecessary credit cards and any other unneeded documents that could compromise（危及...的安全）your identity if lost or stolen while you’re on vocation.
Then make a photocopy of the cards you’ve decided to take along and keep it in a secure location with you（not in your wallet）or leave it with a trusted relative or friend back home. Then you will know who you need to contact and how to reach it if your wallet is missing.

There was once an 11-year-old boy who went fishing every time he went to an island in the middle of a New Hampshire lake.
On the day before bass (巴斯鱼) season opened, he and his father were fishing early in the evening, catching other fish with worms. Then he tied on a small silver lure (鱼饵) and put it into the lake. Suddenly the boy felt something very big pulling on the lure. His father watched with admiration as the boy skillfully brought the fish beside the bank. Finally he lifted the tired fish from the water. It was the largest one he had ever seen, but it was a bass.
The boy and his father looked at the big fish. The father lit a match and looked at his watch. It was 10 pm — two hours before the season opened．He looked at the fish, then at the boy. “You’ll have to put it back, son,” he said．
“Dad!” cried the boy. “There will be other fish,” said his father. “Not as big as this one,” cried the boy. He looked around the lake. No other fishermen or boats could be seen in the moon-
light. He looked again at his father.
Even though no one had seen them, nor could anyone ever know what time he had caught the fish, the boy could tell from his father’s v
oice that the decision couldn’t be changed．He threw the huge bass into the black water.
The big fish disappeared. The boy thought that he would never again see such a big fish. That
was 34 years ago. Today the boy is a successful architect in New York City. He often takes his own son and daughters to fish at the same place.
And he was right. He has never again caught such a large fish as the one he got that night long ago. But he does see that same fish ... again and again ... every time he has an ethical (道德的) decision to make. Fo
r, as his father had taught him, ethics are simple matters of right and wrong. It is only the practice of ethics that is difficult.．How did the father feel when he saw his son skillfully pulling a big fish out of the water?

| A．The boy and his father discussed what to do with the big fish. |
| B．The boy threw the bass back into the water willingly. |
| C．The father made a decision that the fish must be set free. |
| D．They worried other fishermen might know what they had done. |
The successful architect went fishing with his children at the same place because .
| A．they might catch a big fish there | B．he remembered the moral lesson from his father |
| C．he wanted to remember his father | D．their children enjoyed fishing there |

We’re raising children!
A famous research scientist was being interviewed why he was so much more creative.He had been trying to remove a bottle of milk from the refrigerator when he lost his balance and it fell, spilling its contents all the kitchen floor—a veritable sea of milk!
When his mother came into the kitchen, instead of yelling at him, she said , “Robert, what a great and wonderful mess you have made! I have rarely seen such a huge puddle of milk.Would you like to get down and play in the milk for a few minutes before we clean it up?”
Indeed, he did. After several minutes, his mother said,“You know, Robert, whenever you make a mess, eventually you have to clean it up and restore everything to its proper order. We could use a sponge, a towel or a mop. Which do you prefer?” He chose the sponge and they cleaned up the spilled milk.
His mother then said, “You know, what we have here is a failed experiment in how to effectively carry a big milk bottle. Let’s fill the bottle with water and see if you can discover a way to carry it without dropping it.” The boy learned that if he grasped the bottle at the top near the lip with both hands, he could carry it without dropping it.
This scientist remarked that it was at that moment that he knew he didn’t need to be afraid to make mistakes.
Wouldn’t it be great if all parents would respond the way Robert’s mother responded to him?
| A．Instead, he learned that mistakes were just opportunities for learning something new. |
| B．Well, the damage has already been done. |
| C．What set him so far apart from others? |
| D．What a wonderful lesson! |
E.So, how would you like to do that?
F.Such an opportunity of experiencing was delightful to him.
G. He responded that it all came from an experience when he was about two years old.
A research shows that humans switch from selfish to unselfish behaviour when they are watched. Do you? A picture of a set of eyes on a computer screen can cause a change in the way people act. Even images of eyes on a charity donation collection box encourage people to be unselfish, because people put more money in a collection box that has a picture of eyes on it than they do when a flower symbol is on the box.
Manfred Milinski from the Max-Planck Institute for Evolutionary Biology in Germany and Bettina Rockenbach of the University of Berlin, the authors of a new study, found that people act better when they are being watched because they feel they will be rewarded for good behaviour. Their report also referred to other researches showing that this response of behaving well when watched is somehow coded into humans, and people respond this way unconsciously, or without realising it.
It is not just humans that act unselfishly when they are being watched. A fish called the grooming fish cleans other fish. When other fish are around, it is gentler. When no other fish are around, however, the grooming fish bites chunks from the fish it is supposed to be cleaning.
The researchers suggest that the best way to get people to behave in the correct way is to make them feel watched. This could be the reason for the success of a famous American army poster. On it was a picture of an elderly man staring fiercely and pointing, it appeared, to the person who was looking at the poster. Under the picture was the caption “I Want You”. It encouraged hundreds of thousands of young American men to join the army during the Second World War to fight the Germans and Japanese.The underlined word “coded” (paragraph 2) is closest in meaning to.
| A．hidden | B．programmed | C．forgotten | D．learned |
What is the text mainly about?
| A．It describes changed behaviour when observed. |
| B．It details ways to control people's behaviour. |
| C．It tells how to make people work harder. |
| D．It discusses different advertising methods. |
According to the text, which of the following statements is true?
| A．People pretend to behave better when they are watched. |
| B．Fish bite other fish in a fish tank when they are alone. |
| C．People donate more money when they feel they are watched. |
| D．Soldiers fought better during World War II because of a poster. |
Where would the study described in the text most likely be found?
| A．In a newspaper. | B．In a scientific journal. |
| C．In an advertising magazine. | D．In a science textbook. |
Michael Fish may soon be replaced as a weather forecaster by something truly fishier---the shark(鲨鱼).
Research by a British biology student suggests that sharks could be used to predict storms.
Lauren Smith, 24, is close to completing her study on shark’s ability to sense pressure. If her studies prove the theory, scientists may be able to monitor the behavior of sharks to predict bad weather.
Miss Smith had previously studied the behaviour of lemon sharks in the Bahamas.
She then used their close relatives, lesser spotted dogfish, for further research at Aberdeen University. Her work---thought to be the first of its kind to test the pressure theory ---- resulted from the observation that juvenile blacktip sharks off Florida moved into deeper water ahead of a violent storm in 2001.
Miss Smith said: “I’ve always been crazy about traveling and diving and this led me to an interest in sharks.”
“I was delighted to have been able to research in the area for my degree. I know there’s so much more we need to understand ---- but it certainly opens the way to more research.”
It has been discovered that a shark senses pressure using hair cells in its balance system.
At the Bimini Shark Lab in the Bahamas, Miss Smith fixed hi-tech sensors to sharks to record pressure and temperature, while also tracking them using GPS (Global Positioning System) technology.
In Aberdeen, she was able to study the effects of tidal(潮汐的) and temperature changes on dogfish----none of which were harmed. She also used a special lab which can mimic(模拟) oceanic pressure changes caused by weather fronts.
She is due to complete her study and graduate later this year. She says she will be looking for a job which will give her the chance to enrich her experience of shark research.The passage is most probably taken from _____.
| A．a short-story collection | B．a popular science magazine |
| C．a research paper | D．a personal diary |
What do we learn from the first four paragraph of the passage?
| A．Sharks may be used to predict bad weather . |
| B．Sharks’ behaviour can be controlled. |
| C．Michael Fish is not qualified for his job. |
| D．Lauren Smith will become a weather forecaster. |
Lauren Smith conducted her research by _______.
| A．removing hair cells from a shark’s balance system |
| B．measuring the air pressure of weather fronts |
| C．recording sharks’ body temperature |
| D．monitoring sharks’ reaction to weather changes |
What is the passage mainly about?
| A．A popular way of forecasting weather. |
| B．A new research effort in predicting storms. |
| C．Biologists’ interest in the secrets of sharks. |
| D．Lauren Smith’s devotion to scientific research. |
