It was a perfect day, just the right kind of day to go fishing.

My 13-year-old son Jonathan and I had been 26 this trip for weeks, and now we were sitting on the shore of a beautiful lake.

　 We 27 and talked, and then, suddenly, I saw small 28 where my float(浮子) had been. I waited, 29 it would pop right back up again, but the 30 stayed underneath the water and my heart started to beat 31 . After a few more seconds, my fishing rod was suddenly pulled off the stick it was leaning on 32 me and it was being dragged towards the water.

　 I firmly caught hold of the fishing rod and lifted it up. This fish was 33 ! Slowly, my son balanced on two rocks and leaned down to get the giant off the fishhook.

　 For just one second, he lost his 34 and reached up with his right hand to steady 35 . At that moment, our huge fish got off the fishing line and started to swim 　36 .

　 I saw tears streaming down Jonathan’s face. “Dad, I’m sorry. I’ll never be able to 37 this up to you.” I reached out and put my hands on his shoulders. I said the following 38 almost without thinking. “Jon, how did you feel 39 I was reeling(往卷轴上绕起) that fish in? Were you excited?” He nodded and said, “ Dad, I’ve never been so 　40 in my whole life!” I replied, “ Jon, wasn’t that about the most fun thing we’ve ever done together?” He nodded his head in 41 . Then I said, “So, why should we let a fish getting away 42 possibly the best experience we’ve ever had? Let’s be happy about the fun we did have.”

　 My son, 43 his arms around me and said, “ Dad, I love you so much!” I 44 him back and said softly into his ear, “I love you too, Jon.”

　 We 45 did catch that big fish. But I’ve known ever since that I didn’t let the most important thing get away that day.

It is only during the last few years that man has generally realized that in the world of nature a balance exists between all forms of life. No living thing can exist by itself. It is part of a system in which all forms of life are joined together. If we change one part of the nature order, this will almost certainly bring about changes in some other parts.

　　The cutting of forests reduced the supply of oxygen. The killing of weeds and insects by chemicals led to the wide-spread poisoning of animals and birds. The throwing of waste products into the ocean hurt life in the sea, while waste gases changed the chemical balance of the atmosphere and shut out some of the sun’s necessary life-giving rays.

　　And so we could go on adding more examples until in despair(绝望) we might feel like giving up the struggle to control these harmful human activities. Man is very clever at changing the world around him to satisfy his immediate needs, but he is not so clever at looking far ahead, or at thinking about what the future results of his action might be. Man may well destroy himself because of his silly action.
