Guided Writing and Translation

Translation

If you want to stay young, sit down and have a good think. This is the research finding of a team of Japanese doctors, who say that most of our brains are not getting enough exercise. And as a result, we are aging unnecessarily soon.

The findings show in general terms that contraction of the brain begins sooner in people in the country than in the towns. Those least at risk, doctors say, are lawyers,

followed by university professors and doctors. White collar workers doing routine work in government offices are, however, as likely to have shrinking brain as the farm worker, bus driver and shop assistant.

Doc tors’ findings also show that thinking can prevent the brain from shrinking. Blood must circulate properly in the head to supply the fresh oxygen the brain cells need. “The best way to maintain good blood circulation is through using the brain”, they say, “Think hard and engage in conversation. Don’t rely on pocket calculators.”

Part D: Literary Appreciation

The Catcher in the Rye

1.By saying "you don't like anything that's happening", Phoebe means that Holden is angry

about the world but he doesn't know how to deal with the problems. He fails to win recognition from people around him and he himself regards the outside world as corrupted with phony people. Phoebe points out his problem and makes Holden more depressed.

2.James Castle, Holden's schoolmate, was maltreated by six students in the same school and

finally jumped down from the window. The six students were not punished. Holden regards this as persecution of the corrupted and phony society over innocent youth. He becomes very depressed.

3.Holden is extremely disappointed with the present situation, so he cannot find anything good

in the real life. All he can see around him is violence, cheating and corruption, so he can only cherish a dream.

4.He thinks the adult world is disgusting with cheating and corruption. He hates it and is afraid

of entering it, so finally he goes mad.

5.Holden's dream is to be "a catcher in the rye, protecting innocent children from falling off the

cliff". That is to protect the innocent children from the persecution of the corrupted adult world.

6.Phoebe is innocent, clever, considerate and pretty. So he may be the ideal child Holden wants

to protect from the corruption of the adult world in his dream.

7.Maybe not. It is related to the character traits of Holden. Besides, the outside world is so

powerful and overwhelming.

8.Holden is described as a rebel of the modern world. He is sensitive enough to see all the

corruption, meaninglessness, hypocrisy of the society, but he can find no way to change the situation. So finally he is sent to a mental hospital.
