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.
Some rainwater sinks into the ground. It's good for the thirsty plants. Most of the water goes back to the seas, rivers and lakes, And the water cycle will start all over again.
【參考譯文】
在太陽(yáng)的照射下,水從大海、河流和湖泊上蒸發(fā)。當(dāng)水蒸氣上升時(shí),云就在空中形成了。當(dāng)云升高后,就變涼了,最后變成了一滴滴的水。當(dāng)水變得足夠重時(shí),就作為雨水落到地面上。
有些雨水深入到地面,這對(duì)干渴的植物有益。大部分水又返回大海、河流和湖泊。然后水的循環(huán)過程將再進(jìn)行一次。
