If you want to keep healthy, you should have good habits. What is a habit? It is something we do very often. We don’t even think when we do it. It has become a part of our lives.
“Early to bed, early to rise makes a man healthy, wealthy and wise.” This is an old English saying. Do you know what it means? It means that we must go to bed early at night and get up early in the morning. If we do, we shall be healthy, rich and clever.
Is this true? Perhaps it is. We know the body must have enough sleep. Boys and girls need eight or nine hours’ sleep every day.
Some people go to bed late at night and get up late in the morning. This is a very bad habit. Then you will not think or do your work well. Of course, you can’t be healthy, wealthy or wise.
When we get up early in the morning, we can go out and do morning exercises. Exercise means doing things with the body. Walking, running jumping, swimming, and playing ball games are all exercise. If we don’t exercise, our body will become weak.
Exercise helps the blood (血液) to move around inside our body. Blood takes food to all parts of our body.
Our body also needs air to breathe. Without air, we will die. We must have lots of clean fresh air if we want to be healthy. That is why many people like to go out to do morning exercise.
【小題1】From the passage we know that it is good for our health to ____ .

A.eat a lotB.go to bed earlyC.get up lateD.go to bed late
【小題2】How long should young boys and girls need to sleep a day?

  Chess-playing machines were a common feature at the 19th century carnivals(狂歡節(jié)) .They would take on all competitors and usually wan, but they were all frauds(騙局)with human beings concealed inside.

  Two centuries later, the “machine” is real.

  A computer programmer Deep Fritz held world champion, Vladimir Kramnik, to a 4-4 tie. In doing so, Kramnik felt just short of avenging (復(fù)仇)the 1997 defeat of his predecessor Garry Kasparov at the hands of IBM's Deep Blue.

  Deep Fritz is a commercially available product produced by Germany's Chessbase Gmbh. In this match it was running on 8,900 Mhz processors and could analyze 3 million positions a second.

  Kramnk admitted he found the match exhausting. “ I need some time to recover. ”he said comparing the match with his 2000 defeat of Kasparov. “The pressure is similar but preparing against a computer is much more difficult. It has all the knowledge and you have to be prepared for all openings. With a human, you know that certain openings don't suit his style and won't happen, but not with a computer. ”

  “The games themselves were different,” he said, “Against a computer, you have a feeling that if you make one mistake, it's over. So it's like going through a minefield. You're always watching for tactics, even in a quiet position.”

  He also said that computers play faster. “The game has a different rhythm and it puts more pressure on you.”

  “The main problem, ”he said, “is that you can never understand its logic. In a human sense, it has no logic. With a human opponent, you feel him and you know what path he will take.”

  Chess enthusiasts have been arguing for centuries whether it's an art, a science, a sport or something else.

  Kramnik doesn't see the emergence of computers making any difference to this argument. “Chess is very wide. It's not merely these things but a small model of the world. ”

  Next spring, Kramnik is scheduled to defend his title as Einstein Classical Chess World Champion against Peter Leko of Hungary. While he welcomes a rematch against Fritz, it's not certain when it will take place.

1.The difficulties of competing with the computer doesn't lie in that ________.

[  ]

A.you can never understand its logic

B.the computer plays faster

C.it has all knowledge and you have to prepare for all openings

D.if you make one mistake, it's over

2.The underlined word “exhausing” ( in Para. 5 ) means ________.

[  ]

A.making something interesting

B.making someone excited

C.making someone tired

D.making something endless

3.Put the following events in the right order:

(1) Garry Kasparov was defeated by Deep Blue .

(2)Chess-playing machines were not real.

( 3 ) After competing with Deep Fritz, Kramnik felt exhausted .

(4)Kramnik's competition with Peter Leko of Hungary.

[  ]

A.(2)-(4)-(1)-(3)

B.(2)-(1)-(3)-(4)

C.(2)-(3)-(4)-(1)

D.(1)-(A)-(3)-(2)

4.What did Kramnik think of the chess?

[  ]

A.It became more and more difficult after the chess-playing machines were invented.

B.Chess is an art, a science, a sport, etc.

C.It's more and more popular, with the computer developing.

D.Chess is a small world which is wide.
