【题目】Sorry to say, our brains naturally start slowing down at the cruelly young age of 30. It used to be thought that this couldnt 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 were younger. All thats 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 in which the brain deals with information. Since much of the data we receive comes through speech, the Brain Fitness Program works with language and hearing to better speed and accuracy.

Over the course of training, the program starts asking you to distinguish sounds (between dog and bog, for example) at an increasingly faster speed. Its 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 youre pretty quick.

The biggest finding in brain research in 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 aging, you really do do it or lose it, says Barbara Sahakian, professor at Cambridge University.

【题目】My husband Ollie had retired from teaching and we were making plans to travel together to Florida. Then he was terribly ill and became very weak, hardly able to speak. Weeks passed and it became clear that Ollie was near death, but I prayed day and night that he could get better.

One of us was always in Ollie's hospital room--either me, or our grown children, Bruce and Karen. One day, in his broken and weak speech, Ollie told Bruce, Go home. You should be with Gwen. Gwen was Bruce's wife. They had been married for six years and lived hundreds of miles away. Gwen was about to have a baby. We felt an extra sadness, knowing Ollie would never see his first grandchild.

I don't want to leave you, dad, Bruce said. Ollie repeated, You should be with Gwen. Reluctantly, Bruce left. When the baby comes, he promised Ollie, you will be the first to know. A few days later, around 2 p. m., Ollie awoke from a sleep. He turned and looked at me. I sat close to hear his weak words. The baby is coming now. It's a boy, he said. For a moment his eyes were filled with tears. Then he went back to sleep again. Not long after that, Karen ran into the room. Bruce called, she said, a smile lighting her face. Gwen gave birth to a healthy baby boy around two o' clock.

Ollie smiled; he had been the first to know. That night, Ollie died in his sleep.
