A mother in Australia was told by a doctor that her new born son was dead but she helped to bring him back to life by holding the baby against her body. She used a method known as a kangaroo care. The child, named Jamie ,was born after only 27 weeks with his twin sister, Emily, in a hospital in Sydney. Her birth went well ,but his was a different story. The doctor struggled for 20 minutes to save Jamie before announcing him dead.

“His little arms and legs were just falling down away from his body.” Kate Ogg said ,“I took off my coat and put him on my chest with his head over my arm.” She and her husband, David ,said to the child as she continued to hold him for nearly 2 hours. During that time, the two-pound baby showed the sign of life. She said , “I told my mum ,who was there, that he was still alive. Then he held out his hand and grabbed my finger. ”Their tiny baby grew stronger and stronger in his mother’s arms, and their final goodbye turned into a hello.

The doctor at first ignored the baby’s movements, but when he put the stethoscope（听诊器）to his chest, his mouth was wide open and he said ,“It’s my fault, It’s a miracle( 奇迹).

“The kangaroo care helps the baby keep body warmth” Dr Pinchi Srinivasan said, “It also regulates(调节) heartbeat and breathing rates and is believed to help weight gain and improve? sleeping habits. Fathers can also use kangaroo care. The key to the method is skin-to-skin contact.”

?? The practice began in less developed nations. It has become a recognized pracitce in helping premature babies. The techniques is good for babies, and is used in many baby care centers.

Sorry to say, our brains naturally start slowing down at the 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 and hearing to better speed and accuracy （准确性）.Over the course of training, the program starts asking you to tell 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. 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.

51. According to the new studies, what will happen to our brains?

A. They will not start slowing down until the age of 30

B. They will start working slowly after the age of 30

C. They can work as well as at a young age through certain exercises

D. They can not be improved once they start to slow down

52. The writer mentioned many ways to speed up your brain, EXCEPT_____

A. doing a million new activities　　

B. sleeping as much as possible　

C. playing some intelligent games

D. playing table tennis

53. What can we learn from the text?

A. Using right tools is important for brains’ work.　　

B. Brain research deals with information from the Internet　

C. Dr. Merzenich is a scientist in computer,

D. Many activities can keep our brains young.

54. Which of the following agrees with the writer’s idea?

A. The train methods work better for the old.

B. People should train the brain to stop it from aging.

C. The training of the brain should start at an early age.

D. It is necessary to take part in as many activities as possible.

55. Which one is TRUE according to the passage?

A. If you are 71 years old, your brain is too old to train.

B. You can eat the food to keep your brain young and plastic.

C. Merzenich has developed a computer-based training method to train brains.

D. You will feel younger when you train your brain.
