学生习作：
　As we know, good moods are important to us. Smiling at life is good for our health. So we must learn to be in good spirits.
   First, doing sports can help you be in good spirits. Then, do① what you like in your free time can also help you keep② in good spirits. Finally, talking to others is a good way, too.
　If you want to be in good spirits, please follow my advice.
点评：
　　①此处应改为doing，为动名词作主语的用法。do为动词原形，不能单独作主语，应改为其动词的v-ing形式。
　　②此处应改为stay。句中keep意为“保持（某种状态）”，其后接形容词，保持良好的心态应用固定搭配stay in good spirits。
总评：
　　小作者从三个方面条理清晰地叙述了应该怎样拥有良好的心态，first，then 和finally的运用使整篇文章层次分明、脉络清晰。希望小作者继续夯实基础知识，写出更加优秀的作文。
