My husband had just bought a new washing machine for me. I decided to use it the _36 day, and I washed a lot of things.  Everything worked 37 ,  but I couldn’t find 38 of my husband’s socks though I had looked 39 for it. The next morning, I got ready for 40 as usual. When the bell rang, the students came in. I greeted them and told them 41 we were going to do 42 . When I turned 43 to write on the blackboard, the class burst out 44 . They laughed and laughed. They laughed so much, in fact, that I was 45_ the headmaster would be in to see all this. I asked the class to 46 ,  but the 47 I talked ,  the more they laughed.  So I thought I had better pay 48 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 49 came to see 50 all the laughter was about.  When he came in, he started 51 , too. “ Good Heavens!” I said . “ Will 52 please tell me what is so _ 53 ? ” “ Oh, God, ” said the teacher. “ You have a brown 54 stuck (沾) to the back of your shirt. ” So that’s 55 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).” 小题1: A．very B．last C．next D．following 小题2: A．hard B．well C．fast D．slowly 小题3: A．all B．both C．either D．one 小题4: A．nowhere B．somewhere C．anywhere D．everywhere 小题5: A．breakfast B．clothes C．school D．books 小题6: A．which B．what C．how D．why 小题7: A．today B．this day C．that day D．now 小题8: A．around B．back C．off D．over 小题9: A．smiling B．laughing C．crying D．quarrelling 小题10: A．afraid B．doubtful C．sure D．glad 小题11: A．look B．write C．stop D．go on 小题12: A．better B．quicker C．less D．more 小题13: A．further B．more C．hardly D．no 小题14: A．me B．mine C．us D．his 小题15: A．what B．why C．which D．that 小题16: A．writing B．asking C．talking D．laughing 小题17: A．everyone B．anyone C．someone D．he 小题18: A．funny B．wrong C．pleasant D．unforgettable 小题19: A．handkerchief B．sock C．paper D．hair 小题20: A．why B．when C．how D．What
