Question

  Washoe is a young chimpanzee（黑猩猩）. She is no _41_ chimpanzee, though. Scientists are doing a research _2_ her. They want to see how civilized (驯化) she can _43_ . Already she does many things a human being can do.

     For example, she has been learning how to exchange _44_ with people. The scientists are teaching her _45_ language. When she wants to be picked _46_, Washoe points up with one finger. She rubs her teeth with her finger _47_ she wants to brush her teeth. This is done after every meal.

     Washoe has also been _48_ to think out and find answers to problems. Once she was put in a _49_ with food hanging from the ceiling. It was too high to _50_. After she considered the _51__, she got a tall box to stand _52_. The food was still too high to be reached. Washoe found a _53_ pole. Then she climbed onto the _54__, grasped the pole, and __55_ down the food with the pole.

     Washoe _56_ like a human, too. The scientists keep her in a fully furnished house. After a hard _57_ in the laboratory, she goes home. _58_ she plays with her toys. She _59_ enjoys watching television before going to bed.

Scientists hope to _60_ more about people by studying our closest relative (亲属)-chimpanzee.
