Who has deprived the children's happiness of learning???  

Children are born with a natural desire of learning. They are curios and concerned about   36  around them. They are   37  to learn anything that amazes them. They have so many   38   that they keep on asking. They can bore the   39  all day long with many   40  questions which they will never feel bored with. Why? This is because learning is their   41   , perhaps an instinct of human beings. They just can't help. But   42   , they feel bored with learning, especially when learning becomes a boring   43   for them, especially after school has become a    44  of their life, especially when they have to   45   teachers who tell them again and again to   46    to recite and memorize things they don't want to learn, and especially  47    they realize school is not what they once    48   to be but something that, according to their parents, they must rely on in order to   49  a good fame or a good job or a good future. That is to say, learning has become a   50  , which they are forced or   51   to face. So it is the teachers and parents who have thrown the heavy   52  on the children. And meanwhile, the competitive society is also to blame. The children have been   53   of their pleasure and happiness that they could have enjoyed from the natural learning. 

Therefore, my   54  to the students’ learning is that they   55   enjoy learning, enjoy the pleasure that they could feel from learning itself. Find back the long lost desire and curiosity of learning in their childhood.

     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," 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

     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.

1. 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

2. 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

3. What can we learn from the text?

A. Practice makes a quick mind.

B. Brain research started ten yeas ago.

C. Dr. Merzenich is a scientist in computer.

D. People believed nothing could stop the brain slowing down.

4. 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.
