When you hear the word "scientist", what do you think of it? Many people think scientists are people in clean white coats, working in labs( 实验室). Some scientists do work in labs. But there are 1 scientists working in woods and jungles(丛林). These scientists are called " animal behaviour (行为) scientists", and they study animals as they live in nature. Why don't these scientists catch animals and study them in zoos? The 2 is in the word "behaviour". Animal behaviour scientists want to learn 3 animals behave in their wild homes. When animals live in cages or in zoos, they do not act 4 as they do in the wild. They may fight (打架) 5each other, or they may not eat, or they may not raise (抚养) their babies as they usually do. To see real animal behaviour, scientists must go to the places 6the animals live. So animal behavior scientists go into the jungles, the woods or the deserts. There, 7most important tools are their eyes and ears. They watch and listen to the animals very 8. They write down everything that happened in notebooks. Though they live near the animals, the scientists are careful not to frighten them. If the scientists are 9, the animals will pay no attention to them. Then the scientists can see how the animals really live.
The animal behaviour scientists hope what they've learned about animal behaviour can provide clues(提供线索) 10people learn to live with animals together more happily.
