三、阅读短文,完成循环示意图。
Do you know how rain, clouds and snow change (变化)? The sun heats (使……变热) the water in rivers (河), lakes (湖) and the sea (海). The water turns into water vapor (水蒸气) and goes up in the air. When the water vapor gets cold, it becomes water drops (水滴). They get together and make clouds. When there are too many water drops in the clouds, they become rain. When it is very cold, they turn into snow. When it is sunny, the snow becomes water again. The water runs into rivers, lakes and the sea. Then the cycle starts all over
