1.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.2.Water is a common chemical substance that is essential for the survival of all known forms of life.In typical usage,water refers only to its liquid form or state,but the substance also has a solid state,ice,and a gaseous state,water vapor or steam.About 1.460 petatonnes (Pt) (1021kilograms) of water covers 71% of the Earth's surface,mostly in oceans and other large water bodies,with 1.6% of water below ground in aquifers and 0.001% in the air as vapor,clouds (formed of solid and liquid water particles suspended in air),and precipitation.[1] Saltwater oceans hold 97% of surface water,glaciers and polar ice caps 2.4%,and other land surface water such as rivers,lakes and ponds 0.6%.Some of the Earth's water is contained within water towers,biological bodies,manufactured products,and food stores.Other water is trapped in ice caps,glaciers,aquifers,or in lakes,sometimes providing fresh water for life on land.两篇呀
