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.
