Lost And Found 失物招领

I picked up a new red backpack on the playground in the morning of yesterday after our baseball game.There are an English book, a mathmatic book, and a physics textbook in the backpack .Besides,a student ID is also in it. After you see the Lost and Found and you lose the bag ,please call me, whose name is Mary ,in Class 2 ,Grade 9. The number is 1234567.I'm waiting for you !

这我之前也学过，但忘了，这是我在问问找到的。希望对你有帮助！
