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,whose theories on space time and matter helped unravel the secrets of the atom and of the universe,was chosen as"Person of the Century"by Time Magazine on Sunday.A man whose very name is synonymous with scientific genius,Einstein has come to represent more than any other person the flowering of 20th century scientific thought that set the stage for the age of technology."The world has changed far more in the past 100 years than in any other century in history. The reason is not political or economic,but technological一technologies that flowed directly from advances in basic science,"wrote theoretical physicist Stephen Hawking in a Time essay explaining Einstein's significance._________(46)Time chose as runner-up President Franklin Roosevelt to represent the triumph of freedom and democracy over fascism,and Mahatma Gandhi as an icon for a century when civil and human rights became crucial factors in global politics."What we saw Franklin Roosevelt embodying the great theme of freedoms fight against totalitarianism,Gandhi personifying the great theme of individuals struggling for their rights,and Einstein being both a great genius and a great symbol of a scientific revolution that brought with it amazing technological advances that helped expand the growth of freedom."said Time Magazine Editor Walter Isaacson.Einstein was born in Ulm,Germany in 1879._________(47)He was slow to learn to speak and did not do well in elementary school.He could not stomach organized learning and loathed taking exams.In 1905,however,he was to publish a theory which stands as one of the most intricate examples of human imagination in history._________(48)Everything else一mass,weight,space,even time itself—is a variable.And he offered the world his now-famous equation:energy equals mass times the speed of light squared,E=mc2._________(49)"There was less faith in absolutes,not only of time and space but also of truth and morality."Einstein's famous equation was also the seed that led to the development of atomic energy and weapons.In 1939,six years after he fled European fascism and settled at Princeton University,Einstein,an avowed pacifist,signed a letter to President Roosevelt urging the United States to develop an atomic bomb before Nazi Germany did.________(50)Einstein did not work on the project.Einstein died in Princeton,New Jersey in 1955.________（46）A:"Indirectly,relativity paved the way for a new relativism in morality,art and politics," isaacson wrote in an essay explaining Time's choices.B:How he thought of the relativity theory influenced the general public's view about Albert Einstein.C:"Clearly,no scientist better represents those advances than Albert Einstein."D:Roosevelt heeded the advice and formed the"Manhattan Project"that secretly developed the first atomic weapon.E:In his early years,Einstein did not show the promise of what he was to become.F:In his"Special Theory of Relativity",Einstein described how the only constant in the universe is the speed of light.

Stars that are near death can no longer burn due to loss of fuel , and because its temperature can no longer control the gravitational（重力的）force, hydrogen ends up putting pressure onto the star' s surface until it suddenly explodes then collapses.2 Black holes come from stars that are made of hydrogen,other gases and a few metals. When these explode it can turn into a stellar-mass ( 恒星质量）black hole , which can only occur if the star is large enough (should be bigger than the sun) for the explosion to break it into pieces,and the gravity starts to compact every piece into the tiniest particle. Try to see and compare:if a star that' s ten times the size of the sun endsup being a black hole that' s no longer than 70 kilometers ,then the Earth would become a black hole that' sonly"fraction of an inch! 3 Objects that get sucked in a black hie will always remain there,never to brsak fren. But rememberthat black holes can only gobble up（吞噬）objects within a specific distance to it It' s possible for a largestar near the sun to become a black hole,but the sun will continue to stay in place. Orbits (轨道）do notchange because the newly formed black hole, contains exactly the same amount of mass as when it was a star,only this time its mass is totally contracted that it can end up as on biggeer tnan a state. 4 So far, astronomers have figured out that black holes exist because of Albert Einstenin's theory of relativity. In the end,through numerous studies ,they have discovered that black holes truly exist. Since blackholes trap light and do not give off light,it is nearly impossible to detect black goles via a telescope.

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.
