首先，小溪里的水被太阳照射；然后，变成水蒸气；接着（到了空中凝结以后）落下来；最后，形成降水。

Fist应该是"First"，最后应为This is rain.
起初，水在小溪里，经过阳光照射变成了水蒸气。接着落下来，这就是雨。

我想应该是First the water in the stream. Sun shines, they becomes vapour. Then they fall. This is rain.
第一个词是first，Sun后边是shines，后边Then they fall. This is rain.
起初，水在溪流中。太阳照射着，它们变成了蒸气。然后它们落下来。这就是雨。
