I lost my library book yesterday .I looked for it everywhere but I didn't find it .When Wang Mei went home after school ,she picked it up and returned it to the school library.As soon as I knew this , I hurried to the library and thanked Wang Mei .Miss Wang told me to be more careful .From now on I should be more careful with everything.

　　昨天我丟了圖書館的書。我到處找它,但我沒有找到它。當放學后王美回家時,她把它撿起來并返回到學校圖書館。當我知道這個,我趕到圖書館,感謝王美。王小姐告訴我下次要小心。從現在開始我應該會更細心的。
