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, 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. (1)、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： B(2)、The underlined part in the passage shows_. A：the importance of information B：the importance of thinking C：the difference between scientists and ordinary people D：the difference between carpenters and people with other jobs.答案： C(3)、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 times B：does not allow any changes even under different conditions C：can be used for many purposes D：leave no room for improvement答案： A(4)、The author quotes the case of Albert Einstein to illustrate _. A：that measurements are keys to success in science B：that accuracy of mathematics C：that investigations are important in science D：that the mathematical calculations may test his investigations答案： C(5)、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1、On average, a successful lawyer has to talk to several _ a day.

Most people will eat more than they usually do. But doctors find out that what you eat may affect how well you remember things. This is bad news for people who eat too much. Forgetfulness seems to many people an inevitable part of aging. As our bodies grow older, most of us find that many things we should remember are slipping out of minds. But new facts show that it is possible to slow times effects on our minds. Once people thought that the brain could not make new cells, but now studies show that learning new things can help brain grow and keep the illness away from the brain. Professor Eric Kandel, a Nobel Prize winner for his study of the human memory, says the best way to save our memories is to keep our brains in good shape. Through mental exercise, he says, people can keep their memories whole into their 80s and 90s. And Mark Mattson, a professor at the National Institute on Aging, says that reducing the amount of calories fed to older rats and mice by thirty percent can be a good help to learning and memory. While it is hard for many people to go on their diet like that, doctors tell us that even small steps can make big difference.(1)、Doctors find out that _may be bad for your memory. A：delicious food B：eating too much C：drinking too much D：doing exercise答案： B(2)、The underlined word slipping in this passage means _.

A：It was believed that nothing new could help brain grow. B：It is possible for us to slow times effects on our bodies. C：It was not easy for many people to go on their diet ten years ago. D：It is very important for the old to fight forgetfulness.答案： A2、 Oil is so important that it is sometimes called black gold. Almost half of our energy comes from oil. We use it to run our cars and factories and to heat our homes, offices and schools. Many everyday things are made from oil. Your shirt may have oil in the material. The soap you wash your hands with might also be made from oil. Your favorite plastic toy is made from oil. Oil is hard to find, because it is trapped deep under the earth. Once the only way people knew there was oil someplace if it leaked out of the ground. Today, however, we have many ways of finding oil. One tool measures the pull of gravity. Places where gravity is weaker are more likely to have oil. Another tool is sound waves. Sound waves travel through different kinds of rocks at different speeds. We can use them to find the rocks that have oil in them. We need a lot of oil, and we are using up the oil wells we know about. Soon we must find new ways of looking for this black gold. (1)、From this passage, we can know oil is _. A：a kind of rocks B：a source of energy C：black gold D：black rocks答案： B(2)、According to the passage, we can tell that _.
