英语翻译
For about twenty years scientists have tried to teach chimps (黑猩猩) to talk like people.But they have failed.
Chimps hear well.Different words do sound different to them.But chimps don't have a speech center in the brain for speaking as people do.So other ways have been found to teach chimps how to speak.
Plastic pieces of different forms and color were used to teach Sarah the chimp.Each piece stood for one word.Sarah's teachers "wrote" by putting the pieces on a board.Sarah read these messages.Then she "wrote" her answers back.Later Sarah learned more different messages.And she learned to follow directions in the messages.

20年来,科学家们尝试教黑猩猩像人一样的说话,但是失败了.
黑猩猩听觉灵敏,它们确实能分辨出不同的单词发音.但是黑猩猩的大脑里没有能像人类一样说话的语言中心,因此科学家们寻找其他办法教它们说话.
Sarah是只黑猩猩.科学家们用不同形状和颜色的塑料片来教她,每一片代表一个单词.Sarah的老师们把这些塑料片放到一块板子上,以这种方法“书写”.Sarah阅读这些消息.然后,她把她的答案又“写”在板子上.后来,Sarah学到了更多不同的消息,并学会了按照消息里的指示采取行动.
