“Look, Alice,” he said excitedly as he 5 over to the chair where I was sitting. “I found a kite. Could we go outside and 6 it?” Looking out of a nearby window, I noticed it was 7 outside. “I'm sorry. Tripper,” I said, sad to see his 8 expression. “The wind is not 9today. The kite won't fly.”
The 1010-year-old boy replied, “I think it's windy enough. I can get it to fly,” he answered 11he hurried out to the back door.
He ran back and forth, as 12as his ten-year-old legs would carry him, looking back 13 at the kite behind. After about ten minutes of unsuccessful trying, he came back in.
I asked, “How did it 14?” “Fine,” he said, not wanting to admit (承认) the failure. “I got it to fly some.”15 I heard him say secretly, “I guess I'll have to wait for the 16”
