I was afraid. I2and ran to my grandma's room. She picked up the tooth and said, "Don't worry, dear. It's a baby tooth. You will have a new tooth in a few3."
"A new tooth?" I felt very4.
"Yes. But when you get old, your teeth will5out again, but at that time, they won't grow again. So it's not6for old people to eat something hard," my grandma said.
I went out of my grandma's room and thought, "Where can I7the dropped tooth?" Suddenly, a good idea8into my mind, "Why not plant it in the ground? If I look after it well, maybe it would become a big tree. When 9comes, there will be many white and strong teeth10the tree. I can give them to the old people then."
Of course my tooth didn't grow into a big tree, but I won't forget the beautiful dream in my childhood.

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.
