The fable describes a fight between an elephant and a monkey. Both of them think they are more capable than the other. They ask a bird to decide who is better. During their task of picking fruit opposite the river， they help each other and realize that everyone has his own strength and weakness. The fable tells us that only we cooperate with each other can we do the things well by making use of our strength and avoiding our weakness. So in our daily life， no matter what we do， we should learn from each other and work together to do a good job.

This experiment aims to find out whether eggshells dissolve in vinegar.

Before we started， we prepared some water， a bowl， a spoon， an raw egg， and enough vinegar.

Procedure：

First， wash the raw egg with shell in the water.

Then， put it in the prepared bowl， which must be big enough to hold the egg and vinegar.

Next， add enough vinegar with the spoon to cover the egg.

Finally， cover the bowl， and then keep the egg in the vinegar for 48 hours.

To our surprise， we saw that the eggshell had disappeared in vinegar. In conclusion， from what happened in the experiment， we can say that eggshells dissolve in vinegar.

Dear class，

Today I’m going to talk about a kind of traditional art—the Chinese paper cutting.

Paper cutting is one of the most popular forms of folk art. Back to the ancient days， paper cutting was originally for offering sacrifices. Nowadays， the cut-outs of some Chinese characters are used as decorations during the Spring Festival and wedding days in order to increase the joyous atmosphere and express people’s wishes for a lucky year and happy life. The cut-outs of life-like creatures are considered as great presents， which are expected to bring good luck.

Flood Safety Guidelines

Flood is one of the most dangerous natural disasters. It may occur suddenly and sweep away everything. Here are some tips on flood safety.

First， listen to the weather forecasts and move to a safe place immediately if there is an order. Besides， prepare food and clean water as well as a first aid kit.

It is important to move to a place high enough to stay away from floodwater， like the top floor of a building， the roof， etc.

What’s more， never drink floodwater as it is not clean and do not take too much personal property with you. Finally， whatever happens， never give up hope.
