用英语写雨的形成过程

When water is heated,it turns into vapor。It goes up with the air。The air can hold certain amounts of vapor at a certain temperature。As the temperature goes up,the air can hold more。But when the air becomes cooler,it cannot hold that much vapor。Then vapor becomes water。When water falls from the sky,it's called "rain"。After it rains,it becomes water again and is stored again in nature 。 再问： 不好意思哈。我要五年级水平的。。（就是用come from或者become的） 再答： 那你说说下面哪些单词不认识吧？ When water is heated, it turns into vapor。 It goes up with the air。The air can hold some vapor at some temperature。 When the air goes up and becomes cooler and cooler, it cannot hold so much vapor。 Then vapor becomes water。 When water falls from the sky, it's called "rain"。 After it rains, it becomes water again。再问： 不好意思。现在不用了，老师评讲了，不过还是谢谢你！~
