My husband had just bought a new washing machine for me. I decided to use it the  21  day, and I washed a lot of things. Everything worked  22  , but I couldn't find 23  of my husband's socks though I had looked 24  for it.
The next morning, I got ready for 25   as usual. When the bell rang, the students came in. I greeted them and told them   26  we were going to do  27  .
When I turned  28   to write on the blackboard, the class burst out 29  . They laughed and laughed. They laughed so much, in fact, that I was  30   the headmaster would be in to see all this.
I asked the class to  31  , but the 32 I talked, the more they laughed. So I thought I had better pay  33   attention to them and continue to write on the blackboard. When I did this, they laughed even more.
Before long, the teacher who had the room next to   34   came to see 35   all the laughter was about. When he came in, he started  36  , too.
"Good  Heavens ! "I said. "Will   37  please tell me what is so  38 ?"
"Oh, God," said the teacher, " you have a brown 39 stuck to the back of your shirt. "
So that's   40   I found my husband's missing sock.
"Oh, well," I said to the class, "let's just say  you have had an unforgettable lesson on static electricity(静电)."
