The _ 31_ teacher, Mr. Litmus, had asked his students to study some special animal. They would write a short report, and tell the rest of the class their conclusions(结论). Some talked about dogs, others about horses, and some chose fish. But the most interesting _32_ of all was made by little Sophie.

　　　 “I found that _33_ are terribly ill- tempered（脾气坏的）,” she said, very sure of herself.

　　　 Everyone smiled, waiting for her to _34_. Then Sophie explained, “I spent hours in my house, watching flies. When they flied _35_, everything was OK, but when they found a _36_ they would really be noisy. I had always thought they made that _37_ with their wings, but they don’t. With my daddy’s telescope I watched the flies really closely, and saw that what they were really _38_ was shouting and protesting. They were so hysterical (歇斯底里的) that they couldn’t fly out of the window, and they would just _39_ their heads against the glass again and again. If only they had _40_ the butterfly that passed by, they would have seen that the top of the window was _41_. The butterfly tried to tell them, but it had no _42_ at all. The flies just kept on shouting and complaining.”

　　　 Mr. Litmus was _43_, and explained to the class that that form of fly’s behavior had nothing to do with _44_. Instead, it was an example of animals having different _45_ of intelligence .

　　　 And this was what _46_ a big disorder in the science class. Many parents had to come and complain because their children had _47_ their parents among the least intelligent of creatures! This, said the children, was because the parents did nothing but complain, and they _48_ listened to anyone.

　　　 Mr. Litmus had to do a lot of explaining, and quite a few parents _49_. It helped some of them realized that, although they weren’t _50_, they often behaved not terribly intelligently.

I’ve often puzzled over something that happened to me one winter when I was eight. Over the years I had been wondering if my 　31 was nothing more than a kid’s imagination.

　 There was a 　32 near our house. In winter it was the greatest 　33 place in the world. One 　34 all I wanted to do was go skating. I had been waiting for weeks 　35 the water was frozen solid. Mom had one rule: “Never ice-skate alone.” But I couldn’t 　36 any longer that afternoon. So I 　37 my skates under my coat and ran to the pond. Several people were skating near the shore, and some kids were playing hockey. I was not really 38 .

The hockey game had attracted 　39 audience, so I skated in the other direction until their cheering 　40 . But another noise came soon. The ice was cracking beneath me. Freezing water 　41 my body, and I sank like a rock. My feet 　42 the bottom. Just when I thought I wouldn’t last another 　43 , I felt a tap on my shoulder. “Don’t worry,” someone said. I swung my 　44 around. I couldn’t see anybody. But I heard the voice again，“Push your feet into the bottom and you’ll shoot straight up to the surface.” I did as I was told and 　45 . I crawled to the shore and lay down, 　46 . The next thing I knew was people were 　47 around me, covering me with coats.

When I awoke, I was home in my own bed. Mom sat next to me, 　48 my hand. “I saw nobody there. It must be an angel that came to my 49 .” I said. Mom smiled, “I just thank God you’re safe.”

　 For a long time I thought I would 　50 　a more realistic explanation if I just thought hard, but I never did.
