Wind is all around us. You can feel it, but you cannot see it or grab hold of(抓住) it. Wind is very useful. Winds help cool the hot land (土地). Winds help warm the cold land. Winds pick up water from oceans(海洋) and later drop this moisture (水分). That is the rain. Winds carry the seeds of plants from one place (地方) to another. Winds help us a lot.
Of course (当然), not all winds are good winds. Some hot winds stop rain from falling in deserts(沙漠). Very cold winds can kill (杀死) living things. Very big winds can blow down large trees and damage(摧毁) small houses. Even so(虽然如此), we would find it hard to live without(没有) winds.
