Do you suppose Darwin, one of the greatest scientists of all time, really did fools experiments? Or did he do experiments that were so simple and basic that other people just thought they were foolish?

　　Sometimes, people think they already know the answer to a question or the solution (解决办法) to a problem. Sometimes, they really do know an answer or a solution, but without thinking they are important.

　　Charles Darwin didn’t settle for (满足于) just thinking he knew something. And, he believed all things could be important however simple they seemed to be.

　　Suppose you drop sheets of paper that are of exactly the same size and shape. If you drop them at the same time in the same place, they will fall in the same way. Now make one of the sheets of paper into a tight (紧的) little ball and let it drop along with the other sheets. What happens? You have done an experiment that is so simple that you might think it couldn’t be worth anything.

　　But this simple experiment is important. It explains part of our present-day understandings of physics, ideas that were worked out long ago by Galileo and Newton. And these understandings set aside some of ancient Greek physics.

Scientist sometimes stops to look at very simple things and to think very hard about them. Even the simplest idea, which we might think is foolish, can shake the foundations of science.

When I was young， my father used to grow carnations (康乃馨).His carnations were red， pink and white. Everyone who saw them admired them for their beauty.
He took care of them with so much love and   　36　    . Every day he came home from work， he went   straight    to see them. He 　37　 watching them every day. We the kids did too. But he used to tell us， “No one should touch my flowers.”
One day my younger sister， who loved my dad very much， had wanted to help him and she   　38　     the carnations from their stems (枝干) one by one and arranged them  　39　      . She believed that he would be very   　40　    to see them that way.
When mom and I realized what my sister had done， we became completely hopeless. However， my sister had no idea why no one showed her any appreciation. When my dad arrived he went，　41　， straight to see the flowers. When he saw his flowers    lying     on the floor like dead animals， he was 　42　 at first. He looked towards the street， to see if it was any of the  　43　    children who could have done it. Then he entered the living room and looked at mom in silence.
Finally mom， who always taught us to   　44　    no matter what， looked at dad and said： “We have no bad neighbors in our area”. Then with a nice tone she continued： “No outsider did this great job， only your lovely daughter Clémence.” My dad’s face   changed     into 　45　 and then he said： “Do I have a better   　46　     than my lovely daughter？” My younger sister smiled and  　47　    dad tightly.

A land free from destruction, plus 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. 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 the 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 one interested in applied science is 12 trying to make something that has a concrete use. He may try to solve a problem by 13 the theories 14 science or by experimenting through trial and error. Regardless of his method, he is working to obtain 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 had 18 or no training in science might not have made their inventions 19 a groundwork had not been laid by scientists years 20 .
