Sorry to say,our brains naturally start slowing down at the Cruelty 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,”saying 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 and 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 balls 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 brain 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’,”says Barbara Sahakian,professor at Cambridge University.
Dr.Merzenich’s training method mainly depends on ______.
A.speech training
B.computer languages
C.the activities one joins in
D.the information being dealt with
By saying “the brain at any age is highly plastic”,the writer probably means the brain can be ______.
A.used B.mastered
C.developed D.researched
What can we learn from the text?
A.Practice makes a quick mind.
B.Brain research started ten years ago.
C.Dr. Merzenich is a scientist in computer.
D.People believed nothing could stop the brain slowing down.
Which of the following agrees with the writer’s idea?
A.The training methods work better for the old.
B.People should use the brain to stop it from ageing.
C.The training of the brain should start at an early age.
D.It’s necessary to take part in as many activities as possible.

If your head is overheating, you are very likely to yawn(打哈欠) soon, according to a new study that has found the main purpose of yawning is to control brain temperature. The study explains several mysteries about yawning, such as why it’s most commonly done just before and after sleeping, why certain diseases lead to too much yawning, and why breathing though the nose often stops yawning.
“Brains are like computers,” Andrew Gallup, a researcher in the department of Biology at Binghamton University who led the study, said. “They operate best when cool.”
He and his co-workers Micheal Miller and Anne Clark did researches on yawning in parakeets(长尾小鹦鹉) , which have relatively large brains, live wild in Australia, often experience temperature changes, and, most importantly, do not yawn when others yawn, as humans and some other animals do.
For the study, the scientists put parakeets under three different conditions: increasing temperature, high temperature and normal temperature. While the frequency(频率) of yawns did not increase under the latter two conditions, it increased greatly when the researchers increased the temperature.
It’s now believed yawning operates like a radiator(散热器).
If air in the atmosphere is cooler than the brain and body temperatures, taking it in quickly cools blood, which in turn cools the brain. The new findings also explain why tired people often yawn. Both tiredness and sleep loss can increase brain temperature, while yawning can cool down the brain.
In the future, researchers may focus more on brain temperature and its role in diseases and their symptoms. But the new study on yawning changes the popular idea that yawns are just signs of getting tired of something.
49. What’s the best title for the passage?
A. Why don’t people yawn at normal temperature?
B. The yawn explained—it cools your brain.
C. Yawning operates like a radiator.
D. The cause of yawning—finally found out.
50. The main reason why researchers chose parakeets to do the research is that parakeets______.
A. have very large brains
B. live wild in Australia
C. are not affected by others’ yawning
D. experience frequent temperature changes
51. The writer may suggest doing all of the following to stop yawning EXCEPT______.
A. breathing through the nose
B. turning up the heat
C. enjoying some cool wind
D. putting a cold towel on your forehead
52. In which section of a newspaper would you most probably read this passage?

What’s that smell? Do you hear that noise? Taste this! Look at me! Feel this, isn’t it soft? When you hear, or even use these phrases, you probably don’t stop to think about why we use them. Well, it’s because of our senses. Without us even knowing, our sense organs (nose, eyes, ears, tongue, and skin) are taking in information and sending it to the brain for processing. If we didn’t have them, we would not be able to smell, see, hear, taste, or touch anything!
Senses are the physical means by which all living things see, hear, smell, taste, and touch. Each sense collects information about the world and detects changes within the body. Both people and animals get all of their knowledge from their senses, and that is why senses are so important.
All senses depend on the working nerve system. Our sense organs start to work when something stimulates(刺激) special nerve cells, called receptors, in a sense organ. Once stimulated, the receptors send nerve impulses along sensory nerves to the brain. Your brain then tells you what to do. For example, your sound receptors are often attacked by billions of sound waves. When these signals reach the part of the brain called the cerebral cortex(大脑皮层), we become conscious of the sounds.
Our group really learned a lot about the senses while creating this website. We hope that you are able to get just as much out of it. Please feel free to comment about anything on the site by e-mailing us. Also, don’t forget to sign the guest book! Thanks for visiting our site. Come back soon!

Andy rode slowly on his way to school, day-dreaming about the fishing trip that his father had promised him. He was so busy dreaming about all the fish he would catch that he was unaware of everything else around him.
He rode along until a strange sound drew him to the present. He came to a stop and looked curiously up to the heavens. What he saw shocked and terrified him. A huge swarm of bees filled the sky like a black cloud and the buzzing mass seemed to be heading angrily towards him.
With no time to waste, Andy sped off in the opposite direction, riding furiously—but without knowing how to escape the swarm. With a rapidly beating heart and his legs pumping furiously, he sped down the rough road. As the bees came closer, his panic increased. Andy knew that he was sensitive to bee stings(蜇). The last sting had landed him in hospital—and that was only one bee sting! He had been forced to stay in bed for two whole days. Suddenly, his father’s words came to him. “When you are in a tight situation, don’t panic. Use your brain and think your way out of it. ”
On a nearby hill, he could see smoke waving slowly skywards from the chimney of the Nelson family home. “Bees don’t like smoke,” he thought. “They couldn’t get into the house.” Andy raced towards the Nelson house, but the bees were gaining ground. Andy knew he could not reach the house in time. He estimated that the bees would catch up with him soon.
Suddenly, out of the corner of his eyes, he spotted a small dam used by Mr. Nelson to irrigate his vegetable garden. Off his bike and into the cool water he dived, disappearing below the surface and away from the savage insects. After holding his breath for as long as he could, Andy came up for air and noticed the bees had gone. Dragging himself out of the dam, he struggled up the hilly slope and rang the doorbell. Mrs. Nelson took him inside and rang his mother.
“You’ll really need that fishing break to help you recover,” laughed his mother with relief. “Thank goodness you didn’t panic!” But Andy did not hear her. He was dreaming once again of the fish he would catch tomorrow.
