What do I mean in "What am I" in the second grade of primary school?

In what am I in the second grade of primary school, I mean water.

Original text:

I will change. As soon as the sun shines, I turn into steam. Ascending into the sky, I became countless dots, connected and floating in the air. Sometimes I wear white clothes, sometimes I wear black clothes, and I wear a red robe in the morning and evening. People call me "Cloud".

I float in the air and turn into water drops when I meet the cold wind. People call me "rain" Sometimes when I turn into a hard ball and shoot it down, people call me "hail". In winter, I become a little flower, and people call me "snow".

Usually I sleep in the pool, walk in the stream, run in the river, dance in the ocean, sing and have meetings.

Extended data:

"What am I?" From the first volume of the second-grade Chinese textbook published by People's Education Press, read by Cheng Xiao. This article is a scientific essay, which tells the changes of water and its advantages and disadvantages in simple and vivid language.

Water is one of the most common substances on the earth, an important resource for all life, including inorganic compounds and human beings, and the most important component of organisms.

This lesson is anthropomorphic and narrated in the first person, which is friendly and natural to read. It is a good textbook to guide students to read aloud with emotion. As far as the full text is concerned, read it slowly and kindly; Paragraphs and sentences should be varied. The first and second paragraphs can be read as "mysterious". The third and fourth paragraphs should be read differently. For example, "I'm sleeping in the pool", a little quieter means quiet; "Walking in the Stream" has a soothing voice to show leisure. Students are imitative, so we should strengthen the reading of model essays when guiding reading aloud.
