Chimps(ºÚÐÉÐÉ) will cooperate in certain ways, like gathering in war parties to protect their territory. But beyond the minimum requirements as social beings, they have little instinct (±¾ÄÜ) to help one another. Chimps in the wild seek food for themselves. Even chimp mothers regularly decline to share food with their children. Who are able from a young age to gather their own food.

In the laboratory, chimps don¡¯t naturally share food either. If a chimp is put in a cage where he can pull in one plate of food for himself or, with no great effort, a plate that also provides food for a neighbor to the next cage, he will pull at random ---he just doesn¡¯t care whether his neighbor gets fed or not. Chimps are truly selfish.

Human children, on the other hand are extremely corporative. From the earliest ages, they decide to help others, to share information and to participate a achieving common goals. The psychologist Michael Tomasello has studied this cooperativeness in a series of expensive with very young children. He finds that if babies aged 18 months see an worried adult with hands full trying to open a door, almost all will immediately try to help.

There are several reasons to believe that the urges to help, inform and share are not taught .but naturally possessed in young children. One is that these instincts appear at a very young age before most parents have started to train children to behave socially. Another is that the helping behaviors are not improved if the children are rewarded. A third reason is that social intelligence.Develops in children before their general cognitive£¨ÈÏÖªµÄ£©skills,at least when compared with chimps..In tests conducted by Tomtasell, the children did no better than the chimps on the physical world tests, but were considerably better at understanding the social world

The cure of what children¡¯s minds have and chimps¡¯ don¡¯t in what Tomasello calls what. Part of this ability is that they can infer what others know or are thinking. But that, even very young children want to be part of a shared purpose. They actively seek to be part of a ¡°we¡±, a group that intends to work toward a shared goal.

A. Chimps seldom care about others¡¯ interests.

B. Chimps tend to provide food for their children.

C. Chimps like to take in their neighbors¡¯ food.

D. Chimps naturally share food with each other.

A. have the instinct to help others

B. know how to offer help to adults

I just realized that while children are dogs-loyal and affectionate-teenagers arecats.

¡¾1¡¿ You feed it, train it, and boss it around. It puts its head on your knee andgazes at you as if you were a Rembrandt painting. It bounds indoors with enthusiasmwhen you call it. However, around age 13, your adoring little puppy(child) turns into abig old cat(teenager). Then when you tell it to come inside, it looks amazed, as if

wondering who died. Instead of following your doorsteps, it disappears. ¡¾2¡¿

Not realizing that the dog is now a cat, you think something must be desperatelywrong within. Since you're the one who raised it, you assume that you did somethingwrong. Now you're dealing with a cat. Filled with guilt and fear, you redouble yourefforts to make your pet behave. ¡¾3¡¿ Call it, and it runs way. Tell it to sit, and it

jumps on the counter.

Instead of continuing to act like a dog owner, you can learn to behave like a catowner. Put a dish of food near the door, and let it come to you. ¡¾4¡¿ You sit still,and it will come, seeking that warm, comforting lap it has not entirely forgotten. Bethere to open the door for it. One day your grown-up child will walk into the kitchen,

give you a big kiss and say, "You've been working hard all day. Let me get those dishesfor you." ¡¾5¡¿

A. It's so easy to be a dog owner.

B. Children as cats can turn to their parents.

C. You won't see it again until it gets hungry.

D. Then you'll realize your cat is a dog again.

E. Teenagers can understand and appreciate their parents' love.

F. But remember that a cat needs your help and your affection, too.

G. However, all the efforts made before now produce the opposite of the desired

result.
