My School Library（段评：本段是全文的标题,清晰点明了写作主题,简洁明了,完全符合记叙文标题的要求,没有需要修改的地方。修改版：My School Library）

My school library is on the second floor of our classroom building. It is bright and quiet. There are many different kinds of books in it, such as history, science and so on . I often read books there after dinner . The library is a helpful place that (改：where) I can learn much knowledge from books . Reading makes me happy. I want to do something for the library. I will put up some signs to keep it clean. I also plan to help more students understand how important it's .（段评：你这段内容把学校图书馆的位置、环境、藏书和你对它的喜爱都讲得很清楚,用到了初中阶段要求掌握的that引导的限制性定语从句,基础表达非常扎实！有两处小问题可以调整优化:1. 从句连接不当:片段"how important it's"是宾语从句的结构错误,宾语从句要用陈述语序,同时it's的缩写形式在介词后引导的从句里规范书写时要展开为it is。2. 句式偏简单:整段大多是短句,可以适当加入初中课标范围内的过渡词,搭配简单的原因状语从句,让表达更流畅有层次。另外列举书籍类型时补充名词,表达会更准确。修改版：My school library is on the second floor of our classroom building.
