What 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 scientist’s 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 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 Einstein’s 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.12.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 jobs13.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 improvement14.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 investigations15.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.

共用题干Albert Einstein's Brain1.It doesn't take an Einstein to recognize that Albert Einstein's brain was very different from yours and mine.The gray matter housed inside that shaggy head managed to revolutionize our concepts of time,space,motion一the very foundations of physical reality一not just once but several times during his astonishing career. Yet while there clearly had to be something remarkable about Einstein's brain,the pathologist who removed it from the great physicist's skull after his death reported that the organ was,to all appearances,well within the normal range一no bigger or heavier than anyone else's.2.But a new analysis of Einstein's brain by Canadian scientists,reported in the current Lancet, reveals that it has some distinctive physical characteristics after all. A portion of the brain that governs mathematical ability and spatial reasoning一two key ingredients to the sort of thinking Einstein did best一was significantly larger than average and may also have had more interconnections among its cells,which could have allowed them to work together more effectively.3.In 1996,Harvey gave much of his data and a significant fraction of the tissue itself to Dr. Sandra Witelson,a neuroscientist who maintains a"brain bank"at McMaster for comparative studies of brain structure and function.These normal,undiseased brains,willed to science by people whose intelligence had been carefully measured before death, gave Witelson a solid set of benchmarks against which to measure the seat of Einstein's brilliant thoughts.Not only was Einstein's inferior parietal region unusually bulky the scientists found,but a feature called the Sylvian fissure was much smaller than average.Without this groove that normally slices through the tissue,the brain cells were packed close together,permitting more interconnections一which in principle can permit more cross-referencing of information and idea, leading to great leaps of insight.4.That's the idea,anyway.But while it's quite plausible according to current neurological theory,that doesn't necessarily,make it true.We know Einstein was a genius,and we now know that his brain was physically different from the average.But none of this proves a cause-and-effect relationship."What you really need,"says McLean's Benes,"is to look at the brains of a number of mathematical geniuses to see if the same abnormalities are present."5.Even if they are,it's possible that the bulked一up brains are a result of strenuous mental exercise,not an inherent feature that makes genius possible.Bottom line:we still don't know whether Einstein was born with an extraordinary mind or whether he earned it,one brilliant idea at a time.Paragraph 3________A:The InformationB:The Different in StructureC:The ConclusionD:The Research in Einstein's BrainE:Normal Brain in Size and Weight

问答题You can’t know your planet unless you know something about science and technology. School science courses, I remember, concentrated on the unimportant parts of science, leaving the major insights almost untouched. The great discoveries in modern science are also great discoveries of the human spirit. For example, Copernicus showed that --far from being the center of the universe, about which the Sun, the Moon, the planets, and the stars revolved in clockwise homage--the Earth is just one of many small worlds. This is a deflation of our pretensions, to be sure, but it is also the opening up to our view of a vast and awesome universe. Every high school graduate should have some idea of the insights of Copernicus, Newton, Darwin, Freud, and Einstein. (Einstein’s special theory of relativity, far from being obscure and exceptionally difficult, can be understood in its basics with no more than first-year algebra, and the notion of a rowboat in a river going upstream and downstream.)
问答题In this section, there is one passage followed by a summary. Read the passage carefully and complete the summery below by choosing a maximum of three words from the passage to fill in each of the blanks 51-5.Remember to write the answers on the answer sheet. For many years after he formed his Theory of Relativity, Albert Einstein visited many universities in different cities where he gave talks about it. He had his own chauffeur who drove him to where he was to give the talk. The chauffeur sat at the back of the room while he was giving his lecture, and then drove him home. One day, the chauffeur said to Einstein, “Professor, I have heard you give your talk so many times that I know every word of it.” “Do you?” Einstein said with a smile. “Let’s find out, shall we? You give my next talk for me. Nobody knows what I look like where we’re going. I’m just a name to them.” Just before they reached the university where Einstein was to give his talk, he changed places with his chauffeur. The chauffeur’s memory was excellent and he was able to give Einstein’s talk exactly as Einstein gave it. He did not understand a word he was saying, but this did not seem to matter. Then, as he was leaving the university, one of the teachers who had been at the talk came up to him. “Professor Einstein,” he said. “That was a most interesting talk. I’d be grateful if you would answer a question.” The chauffeur hurried on. “I’m sorry,” he said, “but I’m late for my next meeting.” “I’ll walk with you,” the teacher said. “I want to talk to you about the problem.” The teacher walked along beside the chauffeur and asked him to solve a very difficult mathematical problem. The poor chauffeur couldn’t understand the problem, let alone attempt an answer. He did not know what to say. Then he had an idea. “It’s so simple,” he said. “Even my chauffeur could answer it.” He pointed to his car, where Einstein was standing, still wearing the chauffeur’s cap. “This man has a maths question,” he said to Einstein. “It’s so easy I’m sure even you can answer it.” Summary: Albert Einstein was a famous scientist who worked out the Theory of Relativity. He used to travel around the country with his chauffeur giving (1) on mathematics. His chauffeur knew his talk very well so Einstein asked him to give the talk at the next (2) where they did not know him. The chauffeur did well, but afterwards a teacher came up to him and asked him a difficult (3) .The chauffeur did not know the answer but he said, “This problem is so simple I’m sure my chauffeur knows (4) it.” Then he pointed to Einstein still standing (5) beside the car.
