A lion is sleeping on the grass in the forest. A little mouse passes by. It's afraid of the lion very much. It wants to leave as soon as it can. It accidentally(意外地)touches the lion's nose. The lion wakes up(醒来). It's very angry. It wants to eat the mouse.
" Please let me go. One day I can help you." begs the poor mouse.
The lion doesn't think that a mouse can help him. But it is generous(宽宏大量的) and finally lets the mouse go.
Some days later, the lion is caught by a hunter's net(网). The lion is afraid, worried and angry. It shouts very loudly. The little mouse hears its voice. It runs quickly and finds the lion.
" Don't worry, Mr Lion. I'll help you." It runs at one of the ropes(绳子)and cuts it with its teeth. The lion is saved.
