A.We had a math contest today. I am good at math, so I _1_it quickly. I was the first one to _2_ the paper. I was sitting on my seat relaxing, while the teacher shouted, Whose paper is this? I made no response. Some time later, I suddenly realized that I didnt sign my name on the paper. I stood up _3_ and went to the teacher. She helped me find the _4_ paper and sign my name. I would have failed the contest if she hadnt _5_me in time.( )1.A. did B. finis
