A land free from destruction , in addition to wealth , natural resources , and labor supply-all these were important 　 1　 　in helping England to become the center for the Industrial Revolution . 　 2　 they were not enough . Something 　 3　 was needed to start the industrial process(进程) . That “something special ” was men— 　　4　 individuals who could invent machines , find new 　 5　 of power , and establish business organizations to reshape society .

The men who 　6　 the machines of Industrial Revolution 　 7　 from many backgrounds and many occupations . Many of them were 　 8　 inventors than scientists . A man who is a 　 9　 scientist is primarily interested in doing his research 　10　 . He is not necessarily working 　11　 that his findings can be used .

An inventor or anyone interested in applied science is 　12　 trying to make something that has a concrete 　 13　 . He may try to solve a problem by using the theories 　 14 science or by experimenting through trial and error . Regardless of his method , he is working to get a 　 15　 result : the construction of a harvesting machine , the burning of a light bulb , or one of 　 16　 other objectives .

Most of the people who 　 17　 the machines of the Industrial Revolution were inventors , not trained scientists . A few were both scientists and inventors . Even those who have 　 18　 or no training in science might not have made their inventions 　 19　 the groundwork had not been laid by scientists years 　 20　 .

　　　 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.
