They are ways of showing kindness. My husband，Bob，is a pilot，and one day we were invited to a potluck (百味餐) at his flying squadron(飞行中队). The noisy room was filled with mouthy kids and their chatting moms and dads. Our son，Daniel, was only two years old. We let him play with the other kids because it was a safe environment. After a while，he came back with a package of peanut butter crackers and proudly held them out to us. A pilot who asked “Do you know whose this little boy is?”followed him. “He is mine,” I answered, wondering what Daniel might have done. “Well,” replied the pilot, “Ive been passing out crackers to the kids for almost two hours，and your son is one of the youngest guys I gave them to. Hes the only one who said Thank you. What he did makes me pleased.” Daniel smiled and proudly repeated，“Thank you.”6.Pilots and their family were invited to the potluck.A.TB.F答案：A7.Daniel felt very excited when he showed his crackers to his parents.A.TB.F答案：B8.For nearly two hours at least, the pilot served at the party when he found Daniel.A.TB.F答案：A9.Only one kid said “Thank you” to the man when he gave the kids crackers.A.TB.F答案：A10.The pilot felt surprised when he heard the boy said “Thank you”.A.TB.F答案：BWhat makes a person a scientist? Does he have ways or tools of learning that are different from those of others? The answer is “no”. It is not the tools a scientist uses but how he uses these tools that makes him a scientist. You will probably agree that knowing how to use a power is important to a carpenter. You will probably agree, too, that knowing how to investigate, how to discover information, is important to everyone. The scientist, however, goes one step further, he must be sure that he has a reasonable answer to his questions and that his answer can be confirmed by other persons. He also works to fit the answers he gets to many questions into a large set of ideas about how the world works.The scientists knowledge must be exact. There is no room for half right or right just half the time. He must be as nearly right as the conditions permit. What works under one set of conditions at one time must work under the same conditions at other times. If the conditions are different, any changes the scientist observes in a demonstration must be explained by the changes in the conditions. This is one reason that investigations are important in science. Albert Einstein, who developed the Theory of Relativity, arrived at this theory through mathematics. The accuracy of his mathematics was later tested through investigations, and Einsteins ideas were shown to be correct. A scientist uses many tools for measurements. Then the measurements are used to make mathematical calculations that may test his investigations.11.What makes a scientist according to the passage? _A.The tools he uses.B.The way he uses his tools.C.His ways of learning.D.The various tools he uses.答案：B12.The underlined part in the passage shows_.A.the importance of informationB.the importance of thinkingC.the difference between scientists and ordinary peopleD.the difference between carpenters and people with other jobs答案：C13.A sound scientific theory should be one that _.A.works not only under one set of conditions at one time, but also under the same conditions at other timesB.does not allow any changes even under different conditionsC.can be used for many purposesD.leaves no room for improvement答案：A14.The author quotes the case of Albert Einstein to illustrate _.A.that measurements are keys to success in scienceB.that accuracy of mathematicsC.that investigations are important in scienceD.that the mathematical calculations may test his investigations答案：C15.What is the main idea of the passage? _A.The theory of relativity.B.Exactness is the core of science.C.Scientists are different from ordinary people.D.Exactness and ways of using tools are the keys to the making of a scientist.答案：D三、词汇与语法16.The man _Mary was so tall that she could hardly see the show.
