   Toto was a baby elephant. Her trunk (象鼻) was only one meter long. When she heard her father making

a noise, Toto raised her trunk, too. The only noise that she could make was very very little, like a toy whistle

(啸叫). (2) Toto saw her mother pulling leaves from the top of a tree to eat them. She tried to reach the

lowest (3) branch, but she couldn't. So her father and mother had to help her to break the branch and it fell

down to the ground. Toto was happy that she could eat the leaves.

    As it was a hot day, flies (苍蝇) sat in the corners of her eyes. She shook (摇) her head, but the flies

stayed there. She saw her mother pulling some grass with her trunk to drive off the flies.

    (4) Toto 发觉这一点都不难。When the elephant walked to a river, her father would help her have a bath

(洗澡). He put the water in his trunk and poured (倾泻) it onto Toto's back. She was very happy and cool.
