阅读理解。     Sorry to say, our brains naturally start slowing down at the young age of 30. It ud 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 theright 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 purpo: a few exercis for the mind.      Merzenich has developed a computer-bad training method to speed up the process (过程) in which thebrain 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 thecour of training, the program starts asking you to distinguish (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 youfaster and faster to keep you challenged. You may start out slow, but before long you're pretty quick.      The biggest finding in brain rearch 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 brainyoung and plastic you can do one of a million new activities that challenge and excite you:playing table tennisor bridge, doing crossword puzzles, learning a language...."When it comes to preventing ageing, you really do 'u it or lo it'," says Barbara Sahakian, professor at Cambridge University. 1.

A. will not start slowing down until the age of 30 B. will start working slowly after the age of 30C. can work as well as at a young age through certain exercisD. can not be improved once they start to slow down 2.What can we learn from the text? A. Using right tools is important for brains' work. B. Brain rearch deals with information from the Internet. C. Dr. Merzenich is a scientist in computer.D.
