Washoe is a(n) ______ chimpanzee.
【正确答案】
C
【答案解析】[听力原文]14-17
Washoe is a young chimpanzee. She is not ordinary chimpanzee, though. Scientists are doing a research on her. They want to see how civilized she can become. Already she does many things a human being can do.
For example, she has been learning how to exchange massages with people. The scientists are teaching her sign language. When she wants to be picked up. Washoe points up with one finger. She rubs her teeth with her finger when she wants to brush her teeth. This is done after every meal.
Washoe has also been trained to think out and find answers to problems. Once she was put in a room with food hanging from the ceiling. It was too high to reach. After she considered the problem, she got a tall box to stand on. The food was still too high to be reached. Washoe found a long pole. Then she climbed onto the box, grasped the pole, and knocked down the food with the pole.
Washoe lives like a human, too. The scientists keep her in a fully furnished house. After a hard lesson in the laboratory, she goes home. There she plays with her toys. She even enjoys watching television before going to bed.
