示例：
Water is the basis of life. Animals and plants need water. So do we. Without food, we can live for a week, but we can't live for three days without water.
Water also plays an important part in our daily life, because we have to clean our teeth, wash our faces and take a shower every day. In addition, water is needed in cooking as well.
Even though our earth is rich in water resource, there are stll many places lack of water, because of the water pollution. It's a great pity that some people have not realized the importance of water protection. If we continue to pollute the water, we will have no water to drink and die of thirst. So we must cherish the water resource.
譯文：
水是生命的源泉。 動物和植物都需要水。我們也一樣。沒有食物，我們可以活一個星期，但沒有水我們活不過三天。
水在我們的日常生活中也扮演著重要的角色，因為我們每天都要刷牙、洗臉、洗澡。而且做飯的時候也需要水。
儘管我們地球的水資源豐富，但由於水汙染，仍有許多地方缺水。遺憾的是，一些人還沒有意識到保護水資源的重要性。如果我們繼續汙染水源，我們就會沒有水喝，會渴死。所以我們必須珍惜水資源。
