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.
水对生物很重要。没有水就没有地球上的生命。所有的动植物都需要水。人类也需要水。
水是无处不在。即使在世界上最干燥的地方,空气中有一些水。
我们都有发现,水可能是固体、液体或气体。当它是固体,它可能和砖一样硬,是液体的时候,你可以倒出的容器。当它是一种气体,你不能看到或感觉到它。
虽然大约70%的地球表面被水覆盖着,世界上有许多地方仍然运行的水。所以我们要好好利用地球上的水。
