Water

　　 Water is very important for living things. Without water there can be no life on earth. All animals and plants need water. Man also needs water.

　　 Water is found atmosteverywhere. Even in the driest part of the world there is some water in the air.

　　 As we all have found out, water may be a solid, or a liquid or a gas.When it isa solid, it may be as hard as brick, When itis a liquid, you can pour it out of a container. When it is a gas, you cannot see or feel it.

　　 Although about 70 percent of the earth's surface is covered with water,there are many places in the world still running out of water. So we should make good use of water on earth.

　　 水

　　 水對生物很重要，沒有水，地球上就沒有生命。所有的動植物都需要水。人類也需要水。

　　 水幾乎無處不在。即使在世界上最干燥的地方，空氣中也有水。

　　 水，正如你所了解的，有固態、液態和氣態。當它是固態時，它可以像磚一樣硬；當它是液態時，你可以將它從容器中倒出；當它是氣態時，你看不見或感覺不到它。

　　 雖然地球表面70％是水覆蓋著，世界上仍有許多地方缺水。所以我們要好好利用地球上的水。
