Every  47   gets its light either from daylight   48   the window   49   from the lamps or electricity,   50  no matter what kind of light it is, the way it shines towards our books or work is very important to the eyes.
Take a book and sit with your   51   toward the window, and try to read. Your shadow(影子) falls all over the page and makes it   52   for your eyes as if you were in a   53   room.
Now turn around and face the window. The page is   54   shadow again, while the bright light is in your eyes.
Try sitting with your   55  side toward the window. This is very good for   56   , but if you were writing, the shadow   57   fall across the page and bother you  58  .
There is another way – sit  59   your left side to the window. Now everything is perfect for writing as well.
Whatever kind of light is in the room, the rule about the right way to sit is   60   the same.

Long, long ago people made fire from lightening（閃電）. But they had to keep the fire burning, for they couldn’t start it again if there was no lightening. Later, they found out hitting two pieces of stone together could make a spark（火花）. Then spark could burn dry leaves. In this way they could make the fire again if it went out. Then people also learned to make a fire by rubbing（摩擦）. They made a hole in a piece of wood and put a smaller stick into the hole. They turned the stick again and again. After a few minutes they got a fire.

Years went by, people learned other ways to make a fire. Sometimes they used the heat from the sun. They held a piece of glass in the right way and made a piece of paper of fire.

Watson won his most important game and became Southern Chess Master in 1977. He was given the silver cup.

“It isn’t rightly mine,” he said, when he was holding the cup.” “It was won two years ago when I was on holiday in…”

“A family was staying at my hotel at that time. Mrs. Prig, the mother, was told that I played chess; and she begged me to give her young son a game. ‘He’s only ten.’ she said, ‘I’ve been told that he plays quite well. ‘

“Well, as you can guess, I wasn’t too happy. A player likes the opponent (對(duì)手) to play as well as he does. But it was holiday time and I agreed to play. We placed the board in the garden. The game began. I hoped it would be quick — and so it was.

“I soon knew that David Prig was no learner. After ten minutes his sister came outside and began to play tennis against a wall. The boy seemed to lose interest in our game. He moved a piece (棋子) without care. I gave my attention to the board.

“Call me when you are ready, Mr. Watson,” he said.

When I was ready? I looked up. He had gone off to play with his sister. I studied the board, and found I was driven into corner. So it went on with David: a quick move, then tennis, back to the board, then back to his sister. My difficult condition became impossible to change. I was beaten. Oh, so easily, by a ten-year-old chess player. He was the winner—in twenty-eight minutes.

“David Prig, a name to remember. I had a chance to use his game today, and it won this cup for me. To him, of course, it is only one of a hundred, or perhaps a thousand, winning games.” (from www.zkenglish.com)

His talent and charm have made him the No.1Chinese classical artist in the world. And he played in the grand Beijing Olympic opening ceremony in 2008, watched by a TV audience of 5 billion.

　 Lang Lang, 26, is the first Chinese pianist to play with the world's top orchestras (管弦樂(lè)隊(duì)），making his first appearance at the Carnegie Hall in New York at 18, while still a student.

　 Lang's charm and fondness for sharp clothes make him a natural fit to represent China's new international image. According to the British newspaper the Times, "The Lang Lang effect" is responsible for driving 36 million Chinese children to learn the piano.

His cooperation（合作） with the London Symphony Orchestra this month includes a performance of Dragon Songs, an album of traditional Chinese classics.

Behind the international recognition, however, is a fascinating story of a gifted child. Lang grew up with his father's own musical ambition(抱負(fù)) and high expectations. It is not hard to imagine how boring it must be to practice the piano ever3r day. Lang said that he once hated his hands and the piano. He got his right hand hurt six years ago and had to rest.
