Do you know why different animals or pests (昆虫) have their special colors? Colors in them seem to be used mainly to protect themselves.

　　Some birds like eating locusts (蝗虫), but birds cannot easily catch them. Why? It is because locusts change their colors together with the change of the colors of crops(庄稼). When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown color as crops have. Some other pests with different colors from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night.

If you study the animal life, you’ll find the main use of coloring is to protect themselves. Bears, lions and other animals move quietly through forests. They cannot be easily seen by hunters (猎人). This is because they have the colors much like the trees.

Have you ever noticed an even stranger act? A kind of fish in the sea can send out a kind of very black liquid (液体)when it faces danger. While the liquid spreads over (散开), its enemies (敌人)cannot find it. And it immediately swims away. So it has lived up to now though it is not strong at all.

Basketball is still a young game. It's over a hundred years old. In the winter of 1891, a certain college was having some trouble with its boy students. The weather was bad and the students had to stay indoors. As they couldn't play outdoors, they were unhappy, and some even got into fights from time to time.
　　Some of the teachers, at the college asked Dr. Naismith to invent a game so that the students might have something to play with. It was not easy to invent such a game because it had to be played indoors , and the court (球场) was not very large.
　　Dr. Naismith thought for a few days and invented a kind of ball game. It was a fast, wonderful game with much moving and passing of the ball. It was played between two teams. To make a score , the ball had to be thrown into the basket ten feet(英尺) above the floor on the wall . At each end of the court there was such a basket. At first, Dr. Naismith wanted to throw the ball into a box. As he could not find boxes of the right size, he had to use fruit baskets instead. That is how the game got its name.

Once　upon　a　time,　a　young　man　was　standing　in　the　middle　of　the　town　announcing　that　he　had　the　most　beautiful　heart　in　the　world.　A　large　crowd　gathered,　and　they　al　praised　his　heart　for　it　was　perfect.
Suddenly,　an　old　man　appeared　and　said,　“Why　,your　heart　is　not　as　beautiful　as　mine.”
The　old　man’s　heart　was　ful　of　scars（伤疤）.　Some　pieces　of　his　heart　were　removed　and　some　pieces　from　other　people　were　put　in,　but　they　didn’t　fit　quite　right.　So　there　were　several　jagged（锯齿状的）edges.　In　fact,　there　were　stil　some　holes　in　his　heart　where　the　pieces　were　missing.
The　 young　 man　 laughed,“Comparing　yours　with　mine,　mine　is　perfect　and　yours　is　a　mess.”
“Yes,”said　the　old　man.　“But,　every　scar　shows　that　I　took　out　a　piece　of　my　heart　and　gave　it　to　a　person,　and　often　he　gave　me　a　piece　of　his　heart　in　return.”
“Why　do　you　have　some　jagged　edges　in　your　heart?”asked　the　young　man.“Because　the　shapes　of　the　pieces　weren’t　the　same.”“Then　the　holes?”“Sometimes　I　gave　pieces　of　my　heart　away,　and　the　other　person　hasn’t　given　back　a　piece　of　his,　so　… but　I　don’t　care.”“How　come?”“They　remind　me　of　the　love　we　shared.”
The　young　man　was　deeply　moved.　He　walked　up　to　the　old　man,　took　a　piece　of　his　heart　out　and　gave　it　to　the　old　man.
The　old　man　placed　it　in　his　heart,　then　took　a　piece　from　his　old　scarred　heart　and　placed　it　in　the　wound（伤口）in　the　young　man’s　heart.　It　fitted,　but　not　perfectly,　as　there　were　some　jagged　edges.
The　young　man　looked　at　his　heart,　not　perfect　any　more　but　more　beautiful　than　ever.
How　sad　it　must　be　to　go　through　 life　 with　 a　 whole　untouched　heart!
