“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!
