Module 4 Great Scientists【美文阅读】What makes a person a scientist? Does he have ways or toolsof learning that are different from those of others? The answeris“no”．It isn't the tools a scientist uses but how he uses thesetools that make him a scientist.You will probably agree that knowinghow 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 areasonable answer to his question and that his answers he gets tomany questions are into a large set of ideas about how the worldworks.The scientist's knowledge must be exact.There's 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 why 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 investigation.Einstein's ideas were proved to be correct.A scientist uses many tools for measurements.Then the measurements are used to make mathematical calculations that may test his investigations.【诱思导学】Can you list some great scientists?

课后限时作业(十一)(见课时作业P21)[语言知识练]Ⅰ.单句语法填空1．The old man used to make his living by selling(sell) newspapers.2．The price of the house in this city has gone up by 3% so far.3．The floor is so dirty that it really requires washing/to be washed(wash)．4．Our teacher said that the new film was well worth seeing(see)．5．I hear that the girl is hard to get(get) along with.6．Listen!

Leading researchers as well as science fiction writers will attend the event. It c omes as NASA is preparing a multibilliondollar Mars research programme.“Turning the Mars into a little earth has long been a topic in science fiction，” said Dr Michael Meyer, NASA's senior scientist. “Now, with scientists exploring the reality, we can a sk what are the real possibilities of changing the Mars.”Most scientists agree that the Mars could be turned into a little earth, although much time and money would be needed to achieve this goal. But many experts are shocked by the idea.“We are destroyi ng our own world at an unbelievable speed and now we are talking about ruining another planet，”said Paul Murdin from the Institute of Astronomy, Cambridge, U．K.Over the past months, scientists have become increasingly confident that they will find Martian life forms. Europe and America's robot explorers have found the proof that water, mixed with soil, exists in large amounts on the planet.In addition, two different groups of scientists announced on March 28 that they had found signs of methane(甲烷) in the Martian atmosphere; the gas is a waste product of living creatures and could be produced by microbes(微生物) living in the red planet's soil.But scientists such as Dr Lisa Pratt, a biologist at Indiana University, say that these microbes will be put in danger by the little earth project.“Before we have even discovered if there is life on the Mars, we are talking about carrying out projects that would destroy all these native life forms, all the strange microbes that we hope to find buried in the soil，” said Dr Lisa Pratt.Monica Grady, a planetary scientist at the Natural History Museum, London, shares this view.“We cannot risk starting a global experiment that would wipe out the precious information we are looking for，” she said.“This is just wrong.”本文为议论文。
美国的一部分科学家想把红色火星改造成蓝色的“生命天堂”，就这一提议，科学家们展开了辩论。
1．What is the passage mainly about?A．A plan turning the Mars into a little earth.B．The necessity of changing the Mars.C．Finding water on the Mars.D．The Mars supporting life.解析A主旨大意题。
根据第一段可知，人们计划将火星变为一个小地球，下文就这一计划是否应该实施进行了探讨，因此文章是围绕将火星变为小地球这一计划展开的，故选A 项。
2．What could prove the existence of microbes living in the Mars'soil?A．Liquid water on the Mars.B．Some creatures on the Mars.C．A lot of good soil on the Mars.D．Signs of methane in the Mars' atmosphere.解析D推理判断题。
根据倒数第四段可知，科学家在火星上发现了甲烷存在的迹象，而甲烷是生物排放出的一种气体。
由此科学家认为火星上有微生物存在，故选D项。
3．What can we infer from the passage?A．Water is a key factor for life; without it, living on the Mars would be impossible.B．The project won't affect the native life forms supposed to live on the Mars.C．The idea turning the Mars into a little earth is nothing but science fiction.D．Monica Grady is in favour of carrying out the little earth project.解析A推理判断题。
