7、ience than Qian Xuesen.Described by the authors of the Story of Qian Xuesen as a man with“great scientific thought and scientific spirit”who was patriotic and served his homeland with effort,achievement,and devotion,Qian was an extremely well-respected man.Para.1:Introduction Why was Qian called the

8、 father of Chinas aerospace?Born in Hangzhou in 1911,Qian attended schools in Beijing and then entered Shanghai Jiao Tong University to study Railway Mechanical Engineering.However,after the Songhu Battle broke out in 1932,Qian made the decision to switch his major to aviation because he realised th

9、at China needed its own powerful air force to protect and defend the country.Qian went to the United States in 1935 to pursue his graduate studies.Over the course of the 1930s and 1940s,Qian became a pioneer in American jet and rocket technology.As a graduate assistant at the California Institute of

10、 Technology during the 1930s,Qian helped conduct important research into rocket propulsion,and in the 1940s,he and several other people founded the Jet Propulsion Laboratory,now one of NASAs leading spaceexploration centres.After overcoming some difficulties during his final few years in the US,Qian

11、 returned to China in 1955.He received a heros welcome from his homeland and was put in charge of not only developing Chinas rocket science but also its space and missile programme.At that time,China was poor and its rocket science was undeveloped.No institute or university in China offered rocket s

12、cience as a major,and there were no talents or experts in this field in China.Nevertheless,Qian did not let that discourage him from taking on the challenge.When asked“Can we Chinese possibly make missiles?”,his reply was a determined“Why not?We Chinese are able to make the same things that other pe

13、ople make.”Under Qians leadership,China developed the Dongfeng missiles,followed by the first generation of Long March rockets.In 1970,China successfully launched its first man-made satellite,Dong Fang Hong I,from a Long March rocket.Because much of the technology behind the Shenzhou rockets can als

14、o be traced back to Qians research,Qian earned the name of“the father of Chinas aerospace.”patrioticPara.2-5:His personal history and accomplishments accomplishments Try to summarize Qians personal history with your own words.Qian read a lot and was extremely knowledgeable,especially in the area of

15、frontier science research.However,what might have made him such an outstanding and creative scientist was probably his strong interest in other things,such as music and drawing.His deep appreciation for art often gave him inspiration in his scientific research.Para.6:His personality a wide range of

16、habitsPara.7:His death and peoples appreciation of himThe whole country was saddened by Qians death in 2009,and people honoured and remembered him in different ways.Read for detailsStephen Hawking was one of the most famous and gifted scientists in physics.Most people are familiar with images of him

17、 in his wheelchair,unable to move and using a computer to talk.Since he came down with a disease which caused him to lose the use of most of his muscles,his world became one of abstract thought.Para.1:Introduction Para.2:His claim to fameHawking first achieved fame when he was still healthy enough t

18、o walk,as a graduate student in physics at Cambridge University in 1964.In general,there were two main theories on the origin of the universe.The first was the steady state theory,which holds that the universe has no beginning or end.The other was the big bang theory,which holds that the universe be

19、gan at a single point in time and space.The biggest champion of the steady state concept was Fred Hoyle,a professor at Cambridge.During the question and answer period after one of Hoyles lectures,Hawking stood up and pointed out that Hoyle had made a mistake in his maths.Once the maths was corrected

20、,it showed that the big bang theoryand not the steady state theory was true.Hawkings own work on the big bang theory was soon proven by astronomers with telescopes.A star was born.How was Hawkings own theory proven correct?His claim to fame-Para.3:Characteristics that made him greatSo,what made Step

21、hen Hawking a genius?Besides being brilliant,he was brave,though sometimes careless in what he said or did.He was willing to say what others were afraid to say,and to dream of what others were afraid to dream about.Furthermore,he was quite determined.This had help him as a scientist,and had helped h

22、im even more in his fight against his disease.Above all,Hawking was willing to admit his faults.This odd combination of characteristics had made him one of the greatest thinkers of the 20th and 21st centuries.Characteristics that made him greatTry to summarize the words that describe the personaliti

28、uApart from being clever,what are the most important personal qualities a scientist must have to be successful?uHow do these stories illustrate the scientific spirit?Does the writer explain clearly the personal qualities that make up the scientific spirit?Does the writer give examples from the lives

29、 of scientist(s)to illustrate the points?Does the writer describe the personality of a great scientist?Does the writer use appropriate linking words and phrases to tie the ideas together?Does the writer use separate paragraphs,each with its own function?When we consider the great minds of many centu

30、ries and ask the question of what makes someone a great scientist,there are many aspects we should evaluate.But which ones are most important?Is it their inventions,cures,or solutions to problems?Is it the personal challenges they had to face?Or is it their overall character?Looking at the lives of

31、Qian Xuesen and Stephen Hawking,some common characteristics surface:they are knowledgeable,gifted,self-sacrificing for the greater good of the country or humanity,brave,and determined.In short,they have to tenaciously chase down solutions to big problems and not let discouragement set in during thei
