Rain
In the heat of the sun, water evaporates from seas, rivers and lakes. As water vapour rises, clouds form in the air. When the clouds rise high, they get cool. Finally they become drops of water. When they are heavy enough, they fall to the earth as rain.
I like raining because in this city the air is too dry. There too much pollution in the air, which often smells unpleasant. If it rains, the air becomes fresh and wet. Rain gives all the world lives.
雨
在太阳的照射下，水从大海、河流和湖泊上蒸发。当水蒸气上升时，云就在空中形成了。当云升高后，就变凉了，最后变成一滴滴的水。当水变得足够重时，就作为雨水落到地面上。雨给全世界以生命。
我喜欢下雨，因为在这个城市，空气太干燥，又有很多的污染，它很难闻。如果下雨，空气就会变得清新而湿润。
