阅读理解。 One day, my mother and I went shopping at a Chinese supermarket. We found that the crucian carps (鲫鱼) in the seafood counter were very fresh, as a result we chose four crucian carps and handed them over to the seller. As it would take some time to clean the fish and dispose (处理) of their internal organs (内脏), we decided to look around the other places first. When we came back to the seafood counter, I asked the seller for my fish. He raised one, which was being cleaned, to let me have a look and tell me he was still working on the fish. I hurriedly said, 'Go ahead, Go ahead.' I meant for him to go on. Unexpectedly, the seller stopped his work, looking at me with puzzled expression, and asked me in reply, 'Go ahead?' 'Yes,' I said, 'go ahead'. He pointed the fish in all seriousness, and repeated very seriously, 'Head?' Paying no more attention to him, I turned back to chat with my mother. Suddenly, 'Bang, bang, bang,' was heard from the counter. Quickly, the seller passed the four fish without heads to me. I asked loudly, 'Why did you cut all the heads off?' The seller was also very annoyed (颇为生气的) and said, 'Didn't you tell me to go ahead again and again?' On hearing what he said I felt funny as well as angry. It turned out that he considered 'go ahead' as 'cut the head off'. No wonder he asked me several times about it! Taking the headless fish home, I became frightened.
