30、portant research into rocket propulsion, and in the 1940s, he and several other people founded the Jet Propulsion Laboratory, now one of NASAS leading space-exploration centres.1935年，钱学森前往美国读研究生。二十世纪三四十年代，钱学森成为美国喷气式飞机和火箭技术的先驱人物。二十世纪三十年代担任加州理工学院的研究生助理时，钱学森协助开展火箭推进方面的重要研究工作。二十世纪四十年代，钱学森与其他几人成立了喷气推进实验室

31、，该实验室现已成为美国宇航局领先的太空探索中心之一。 As a graduate assistant at the California Institute of Technology during the 1930s，Qian helped conduct important research into rocket propulsion.在20世纪30年代，作为加州理工学院的研究生助理，钱学森帮助进行了火箭推进的重要研究2assistant n.助手；助理；售货员assistance n. 协助，援助come to ones assistance 来帮助某人with the assista

At that time, China was poor and its rocket science was undeveloped. 留学美国的最后几年，钱学森克服困难，于1955年回到中国。他受到了祖国英雄般的欢迎，受命发展中国的火箭科学以及航天和导弹项目。那时候，中国还很贫穷，火箭科学尚不发达。He received a heros welcome from his homeland and was put in charge of no

We Chinese are able to make the same things that other people make.”中国没有一所学院或大学开设火箭科学专业，而且没有该领域的人才或专家。然而，钱学森并不气馁，而是接受挑战。有人问他:“我们

38、中国人有可能制造出导弹吗?他的回答十分坚定:“有什么不能的，外国人能造出来的，我们中国人同样能造得出来。” Under Qians leadership, China developed the Dongfeng missiles, followed by the first generation of Long March rockets. In 1970, China successful launched its first man-made satellite, Dong Fang Hong I, from a Long March rocket. Because much of th

39、e technology behind the Shenzhou rockets can also be traced back to Qians research, Qian earned the name of the father of Chinas aerospace.”在钱学森的领导下，中国研制出了“东风”导弹，紧接着又研制出第一代“长征”系列火箭。1970年，中国使用“长征”火箭成功发射本国第一颗人造卫星“东方红一号”。由于“神舟”系列火箭的大部分技术也可追根溯源到钱学森的研究，因此钱学森被誉为“中国航天之父。 Qian read a lot and was extremely k

40、nowledgeable, especially in the area of 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 rese

41、arch.钱学森博览群书，尤其在前沿科学研究领域知识极其渊博。然而，他之所以能成为一名如此杰出、富有创造力的科学家，可能是因为他对音乐绘画等其他事物的浓厚兴趣。他深厚的艺术鉴赏力时常给科研工作带来灵感。On 31 October 2009, the whole country was saddened by Qians death, and people honoured and remembered him in different ways.2009年10月31日，钱学森逝世，举国哀痛，人们以各种方式纪念他缅怀他。 A WORLD OF PURE THOUGHT 一个纯思维的世界 Step

42、hen Hawking was one of the most famous and gifted scientists in physics. Most people are familiar with images of him in his wheelchair unable to move and using a computer to talk.

In general, there were two main theories on the origin of the universe. The first

45、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 began at a single point in time and space. The biggest champion of the steady state concept was Fred Hoyle, a professor at Cambridge. 霍金最早成名于1964年，当时他身

46、体健康，行动自如，是剑桥大学物理学研究生。总的来说，宇宙起源有两大理论:第一个是稳恒态理论，认为宇宙无始无终;另一个是大爆炸理论，认为宇宙始于时空中的一个点。稳恒态概念的最大拥护者是剑桥大学的弗雷德霍伊尔教授。 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, it showed that the

47、big bang theoryand not the steady state theorywas true. Hawkings own work on the big bang theory was soon proven by astronomers with telescopes. A star was born。在霍伊尔的一次讲座中，霍金在问答环节站了起来，指出霍伊尔教授计算有误。错误纠正之后显示大爆炸理论而非稳恒态理论是正确的。不久，天文学家用望远镜观察宇宙，验证了霍金对大爆炸理论的研究。一位明星就此诞生。 So, what made Stephen Hawking a genius

48、? 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. 那么，是什么使史蒂芬霍金成为一名天呢?除了才华横溢之外，他还是一个勇敢的人，尽管有时候言行举止比较随意。他敢说别人不敢说的

49、话，做别人不敢做的梦。此外，他意志坚定。Besides being brilliant，he was brave，though sometimes careless in what he said or did.除了才华横溢外，他还很勇敢，尽管有时说话或做事都很粗心。7besides prep.除之外(还) adv.而且；此外，一般用于句子之前(in addition)(1)Besides being fun and good exercise，swimming is a very useful skill.游泳，除了有趣和锻炼身体之外，还是一项很有用的技能。(2)I dont want to

50、 go. ，Im too tired.我不想去，而且我也太累了。 Besidesexcept 除了之外，指从同类的人或物中排除。except for 表示从整体情况来看，要排除其中的部分特殊情况。apart from 既可以表示besides的含义，也可以表示except或except for的含义。(3) some spelling mistakes，the composition is fairly good.除了一些拼写错误，这篇文章写得很不错。Apart from/Except for用besides，except或except for代替下列句中的apart from(4)Will

51、there be anyone else we know at the party apart from Will and Janet？_(5)You can have any one of the cakes apart from this one. _(6)The road was empty apart from a few cars. _besidesexceptexcept forThis had helped him as a scientist, and had helped him even more in his fight against his disease. Abov

52、e 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.无论是作为一位科学家，还是与病魔作斗争，这种品质对他都大有帮助，最重要的是，霍金敢于承认错误。这些性格特点的奇特组合使得他成为二十世纪与二十一世纪最伟大的思想家之一。Above all，Hawking was willing to admit his faults.最重要的是，霍金
