I played a tennis game against my cousin Ed last week, and I will never forget it.
I had played a lot of games before, but it was one of the most        games I’ve ever had. When Ed first phoned and suggested we play, I       quietly, thinking I was sure to beat him, because I didn’t think Ed could win any games with his fat body.
As long as I can remember: Ed’s been the least physically fit member in the family, but strangely        of himself. His big stomach has always ballooned out between his T-shirt and trousers. Although the family often joked about that, Ed        to buy a larger T-shirt or to lose weight. So when Ed arrived for our game not only with the bottom of his shirt inside his trousers but also with a stomach you could        notice. I was so surprised that I was speechless.
My cousin must have made an effort to get himself into       . As a result, at the point in our game, when I’d have predicted(預測) I would win the game by 9 to 1, it was        7 to 9 —and Ed was leading. The sudden realization was       . We continued to play like two       men. When the score was 16 up. I even thought if I could stay alive. When the game finally ended, my cousin and I were lying on the floor on our backs, too tired to move. In some ways, I think that we        won: I won the game, but Cousin Ed won my respect.
