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.

　　昨天我丢了图书馆的书。我到处找它,但我没有找到它。当放学后王美回家时,她把它捡起来并返回到学校图书馆。当我知道这个,我赶到图书馆,感谢王美。王小姐告诉我下次要小心。从现在开始我应该会更细心的。
