“Mum, I want to make you a bet,” I said. “If I go a whole year without TV, will you give me a hundred dollars?” “Well, if you can 1 do it, …” “Of course I can,” I replied, trying to convince 2 . In fact, all this started from my 3 of a picture in the newspaper. I couldn’t bear to look at that boy. He said that he had 4 one year without TV for a hundred dollars, 5 me with mocking eyes. It seemed he was saying, “I did it, 6 you can’t!”. I glared at the boy’s face. That year I did a lot of things. For example, my father taught me to 7 , which became my favorite sport. 8 winter afternoons snowball wars with my neighbors offered daily drama. I went on bike trips with my friends and swam as much as a fish. It was unbelievable how much 9 I had without TV. I learned so many new games. I guess the 10 thing I learnt, though, was self-motivation(上进心). I started to do my homework. I went from a D student to an A student within a couple of 11 . I used to 12 reading if there were no 13 , but now I began to read and enjoy it. I could arrange off all the pictures just the way I wanted them—my own little TV, right 14 my head! I’m surprised what I did. I got a lot more from the 15 than just the 100 dollars!
