(die)（） Reading comprehensionStephen William Hawking was born on 8 January 1942 (300 years after the death of Calileo) in Oxford, England. His parents house was in north London, but during the Second World War Oxford was considered a safer place to have babies. When he was eight, his family moved to St Albans, a town about 20 miles north of London. At eleven Stephen went to St Albans School, and then on to University College, Oxford, his fathers old college. Stephen wanted to do Mathematics, although his father would have preferred medicine. Mathematics was not available at University College, so he did Physics instead. After three years and not very much work he was awarded a first class honours degree in Natural Science. Stephen then went on to Cambridge to do research in Cosmology, there being no one working in that area in Oxford at the time. His supervisor was Denis Sciama, although he had hoped to get Fred Hoyle who was working in Cambridge. After gaining his Ph. D. he became first a Research Fellow, and later on a Professorial Fellow at Gonville and Caius College. After leaving the Institute of Astronomy in 1973 Stephen came to the Department of Applied Mathematics and Theoretical Physics, and since 1979 has held the post of Lucasian Professor of Mathematics. The chair was founded in 1663 with money left in the will of the Reverend Henry Lucas, who had been the Member of Parliament for the University. It was first held by Isaac Barrow, and then in 1663 by Isaac Newton. Professor Hawking has twelve honorary degrees, was awarded the CBE in 1982, and was made a Companion of Honour in 1989. He is the recipient of many awards, medals and prizes and is a Fellow of The Royal Society and a Member of the US National Academy of Sciences. 語(yǔ)篇解讀：本文主要介紹了英國(guó)著名科學(xué)家霍金的生平。1At his teenage, Stephen WHawking went to the same college as_.AGalileoBhis fatherCIsaac Barrow DIsaac Newton解析：細(xì)節(jié)理解題。根據(jù)文中第一段第四句“At eleven Stephen went to St Albans School, and then on to University College, Oxford, his fathers old college.”可知他和他父親上了同一所大學(xué)。答案：B2Which of the following shows the right order of what happened to Hawking?aHe gained his Ph.D.bHe went to Cambridge.cHe was given a first class honours degree.dHe began to hold the post of Lucasian Professor of Mathematics.eHe went to St Albans School.Aecbad BaecdbCaecbd Dcbdea解析：細(xì)節(jié)理解題。閱讀全文可了解事情發(fā)生的先后順序。答案：A3According to the passage, Stephen WHawking had never spent much time studying_.ACosmology BMathematicsCPhysics DMedicine解析：細(xì)節(jié)理解題。閱讀文章，通過(guò)排除法可知答案。文中的第一段倒數(shù)第二句提到了Physics；第二段第一句提到了Cosmology；同一段第四句提到了他學(xué)了Mathematics。而根據(jù)第一段可知Medicine只不過(guò)是他父親希望他學(xué)的專業(yè)而已。答案：D4Before Stephen Hawking went to Cambridge, _.Athere was no one studying Cosmology in EnglandBthere was no one studying Cosmology in OxfordCthere were only a few scientists studying Cosmology in OxfordDCosmology is widely studied in Britain解析：細(xì)節(jié)理解題。文中第二段第一句話“.there being no one working in t
