Everything worked 2 , but I couldn't find 3 of my husband's socks though I had looked 4 for it. The next morning, I got ready for 5 as usual, when the bell rang , the students came in. I greeted them and told them 6 we were going to do 7 .When I 8 back to write on the blackboard, the class burst out 9 . They laughed and laughed. They laughed so much, in fact, that I was 10 the headmaster would come and see all this. I asked the class to 11 ,but the more I talked, the more they laughed. 12 I thought I had better pay 13 attention to them and 14 to write on the blackboard. As I did this, they laughed even harder. Before long, the teacher who had the room next to 15 came to see what all the laughter was 16 . When he came in, he started laughing, too. "Good Heavens! "I said," Will 17 please tell me what is so 18 ?" "Oh, God, "said the teacher," You have a brown 19 stuck to the back of your shirt." So that's 20 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)." | ||||
