| One day last summer, my five-year-old son Parker and I decided to go fishing. Parker had fished before, but hadn't yet 1 the same hobby as me. We'd go to a farm pond, throw Parker's 2 into the water, and in about three seconds the bobber (浮子) would go under and Parker would get a three-inch fish. Parker 3 all that a great and exciting adventure. Then he was off, throwing rocks in the water, looking for frogs, picking flowers for his mom and generally 4 this whole process of fishing. So on this particular day, I decided to teach Parker a 5 . I had thought Parker could catch no more than a couple. But I 6 wrong. No more than two hours, Parker 7 almost ten. "Wow!" Parker said, "I bet mom won't 8 I caught so many." "She might," I answered, "Now be quiet and try to catch another one." Parker tried, but he couldn't keep his 9 off those already in the bucket(桶). I could tell that something was beginning to 10 him. "Dad," he said. "We're taking these home to show mom, right?" "Certainly," I said. Parker concentrated 11 his bobber for a moment. "How are they going to stay 12 ?" he asked. I expected his question and congratulated myself for having a ready 13 . "Well," I began, trying to be as 14 as possible, "they aren't. I mean, we're going to clean them when we get home. 15 we can eat them, and they'll have to die then, right?" "I guess so," Parker replied. He remained 16 while he caught a couple more. "I've got an idea," Parker announced. "Let's put them back in the 17 ." "I'm with you," I said, 18 the fish free. We stood together and watched them swim lazily back into the green 19 of the water. I had 20 on teaching Parker a fishing lesson, but he turned the tables on me. | |||
