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 earths 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,地球上就没有生命。所有的动植物都需要水。人类也需要水。
水几乎无处不在。即使在世界上最干燥的地方,空气中也有水。
水,正如你所了解的,有固态、液态和气态。当它是固态时,它可以像砖一样硬;当它是液态时,你可以将它从容器中倒出;当它是气态时,你看不见或感觉不到它。
虽然地球表面70%是水覆盖着,世界上仍有许多地方缺水。所以我们要好好利用地球上的水。
