Now there is a chicken.C: There were stars in the sky before. Now there is a moon.【设计意图：由季节变化引出本环节主题Changes of the nature，由于学生在Lets learn已初步接触了新句型，教师通过描述图片冬春变化并板书本课重点句型，引导学生运用句型讨论图片。再通过Memory challenge小游戏讨论大自然的其他变化，对本课时重点语言进行初步操练。】(2) Changes in the school Lets try.T：Today a guest is visiting Yifans school, lets listen and talk about the changes in the school.学生完成课本Lets try的听力练习。 Lets talk.A.
