I come in spring . The grass comes out, the trees turn green and the kites fly in the sky. 

  In summer , it is so hot . People like me best. I can call my friend Cloud to hide the sun . Rain , another friend of mine , will also come .Then it will become cool. 

  In fall , I come again . The grass and leaves turn yellow .And the flowers begin to wither. 

  In winter , people don”t like me .When I come , it will be much colder. 

  Who am I ? Right, I”m Wind .
