Are there any idioms and short stories suitable for the first three minutes of Chinese class?

A man was walking in the forest when he suddenly met a hungry tiger. The tiger roared and jumped up. He ran away as fast as he could, but the tiger ran after him. He kept running until the tiger pushed him to the edge of the cliff.

Standing on the edge of the cliff, he thought, "It is better to jump into the cliff than to be caught by a tiger and killed alive. Maybe there is still a chance. "

He jumped into the cliff and was very lucky to get stuck in a tree. That is a plum tree that grows on the edge of the cliff, and the tree is full of plums.

Just as he was happy, he heard a huge roar from the depths of the cliff. He looked at the bottom of the cliff. It turned out that a fierce lion was looking up at him. The lion's voice made him tremble, but he thought, "The lion and the tiger are both the same beasts, and they eat the same things."

Just put down the heart, and heard a voice. I looked carefully, and two mice were biting the trunk of a plum tree. He was in a panic for a while, and then he was relieved immediately. He thought, "It's better to be killed by a mouse than by a lion."

When his mood calmed down, he saw that the plums were just right, so he picked some and ate them. He felt that he had never eaten such delicious plums in his life. He found a triangular branch to rest, thinking, "Since you are going to die sooner or later, you might as well have a good sleep before you die!" " So I leaned against the tree and fell asleep.

When he woke up, he found that the black and white mouse was gone, and so were the tiger and lion. He climbed the cliff carefully along the branches and finally got out of danger. It turned out that while he was sleeping, the hungry tiger couldn't help it and finally roared and jumped off the cliff.

The black and white mouse heard the tiger's roar and ran away in panic. The tiger who jumped off the cliff and the lion under the cliff fought fiercely, and both of them escaped with injuries.

Truth: There will be many dangers in life, and difficulties and dangers are as inevitable as death. Since it is inevitable, it is better to relax and enjoy what you have now, and you will enjoy the sweet fruit of life inadvertently.
