It's half past four in the afternoon. It's the time for children in the kindergarten to go home. A little boy, Andy is crying. So Mrs Smith, his teacher asks him what is wrong.

Andy sobs(呜咽), "I cannot find my shoes. "

Mrs Smith looks around the classroom and sees a pair of shoes." "Are they yours?"

"No, they're not mine. "Andy shakes his head.

Mrs Smith and Andy look around all over the classroom for the shoes.

Finally, Mrs Smith gives up(放弃), "Are you sure those shoes are not yours?" "I'm sure, "Andy sobs" There's some snow on my left shoe this morning. "
