楼主你好~ 寻物启事的标题应为Lost Lost This morning I dropped my pencil on the playground.It's blue and is about 20 cm long.I'm in great need of it for the text of tomorrow. I need your help! If you find it,please call Li Ming at 1234567 or come to my class.I'm in Class 1,Grade 3. 唔..字数有些不够 ,不过寻物启事/失物招领这类的作文属于小作文 ,字数不用太多 ,我写的这几点就足够. 希望能够帮助到你~
