Yesterday my mother asked me to wash the clothes. Then              

76.      

I used the washing machine to do the job. After that, I had             

77.      

found one of my socks missed. I looked everywhere, but I             

78.       

failed to find them. The next morning I went to school as              

79.       

usually. When I came into the classroom, my classmates burst          

80.       

out laughing. I asked them what was happening, so the more I          

81.       

asked, the more they laughed. At last, our teacher came in see          

82.        

what was matter. When he came in, he started laughing too.             

83.         

"What is so interested? Please'tell me!" I said." You have a              

84.        

brown sock stick on the back of your skirt! "said the teacher.
