Stephen Hawking，the ( http: / / www.21cnjy.com ) most famous theoretical physicist after Albert Einstein，author of A Brief History of Time，was to attend the opening ceremony of a Mathematics Institute at Zhejiang University.
Stephen Hawking w ( http: / / www.21cnjy.com )as born on 8 January,1942 in Oxford，England. When he was eight，his family moved to St.Albans，a town about 20 miles north of London. At age eleven，Stephen went to St.Albans School，and then went on to Oxford University，his father’s old college.Stephen wanted to do Mathematics，although his father would have him prefer Medicine.Mathematics was not available at Oxford University，so he did Physics instead. After three years and not very much work he was awarded a first class degree in Natural Science.
Stephen then wen ( http: / / www.21cnjy.com )t on to Cambridge to do research in Cosmology(宇宙学)，because no one worked in that area in Oxford at that time. After gaining his Ph.D.，first he became a research fellow，and later on a professorial fellow at Gonville and Caius College. After leaving the Institute of Astronomy in 1973，Stephen went to the Department of Applied Mathematics and Theoretical Physics，and since 1979 he has held the post of Professor of Mathematics，which was held by Isaac Newton in 1663.He is a fellow of the Royal Society and a member of the U．S. National Academy of Sciences.
Stephen Hawking has ( http: / / www.21cnjy.com ) been working on the basic laws that govern the universe. He is particularly interested in unifying the General Relativity Theory and Quantum Theory to study black hole.
Sitting in the wh ( http: / / www.21cnjy.com )eelchair，Stephen Hawking, a great man of science，has suffered from a serious disease for decades. In 1963，he caught a disease that couldn’t be cured then. Up to 1974，he was able to feed himself，and private nurse went to his house for an hour or two in the morning and evening. In 1985，he caught pneumonia(肺炎) and had an operation. After the operation，he lost his ability to speak. For a time，the only way he could communicate was to spell out words letter by letter，by raising his eyebrows when someone pointed to the right letter on a spelling card.21教育名师原创作品

Thomas Edison was of ( http: / / www.21cnjy.com )ten said to be the greatest genius of his age. There are only a few men in all history，who have changed the lives of other men as much as the inventor of the first useful electric light. But Edison could never be happy only because someone said he was a genius. “There is no such thing as genius，” Edison said. He said that what people called genius was mostly hard work. But Edison was a dreamer as well as a worker. From his earliest days as a child，he wondered about the secrets of nature. He tried to understand them；then，he tried to learn what could usefully be done with them.
Edison could n ( http: / / www.21cnjy.com )ot know how anyone could be uninterested in life. As he loved to think，he also loved to work. On the day he became 75 years old，someone asked him what ideas he had about life.“Work，”he answered. “Discovering the secrets of nature and using them to make men happier.” He said he had enough inventions in his mind to give him another 100 years of work.
Edison was a ( http: / / www.21cnjy.com )lways poor，and often unsuccessful in his early life. But he never allowed trouble or failure to make him sorry for himself. He always liked to think about the happy things in life.
He said that his dea ( http: / / www.21cnjy.com )fness had helped him in his work，because it had saved him from hearing a lot of foolish talk that would have made him difficult to think.
Edison met and knew ( http: / / www.21cnjy.com ) many of the most famous and important men in the world during his life. He had dined with kings. But he was never able to believe that there was anything special about himself. He was interested in people，not in how famous they were.
He did not understa ( http: / / www.21cnjy.com )nd why people had special favors for him. This was true as much when he was an old man as when he was young. Once，the president of the Pennsylvania Railroad decided that he himself would carry Edison’s bags from the train. Edison was wholly surprised. He couldn’t understand why the man had done this.
He was not proud of his work. “I have tried so many
things I thought ( http: / / www.21cnjy.com ) were true and found out that I was wrong，” he said. He could never forget that he was not always right. All he could do，he knew，was to try everything he could think of to prove that this idea was true，and to continue trying until he would be sure his plans would succeed.

Ⅳ.阅读理解
An international te ( http: / / www.21cnjy.com )am of astronomers has discovered a planet slightly larger than Jupiter that orbits a star 500 light years from Earth. A very good telescope was not even required；they found the planet using several small telescopes much like those used by amateur astronomers.
The new planet ( http: / / www.21cnjy.com ) is named TrES 2 because it is the second such planet found by scientists working on the Trans Atlantic Exoplanet Survey(TrES)．It is a transiting planet(凌日行星)，meaning it can be seen transiting，or moving，across the star it orbits.
Ted Dunham，a ( http: / / www.21cnjy.com )n instrument scientist at Arizona’s Lowell Observatory，says transiting planets are special because researchers can answer a lot of questions about them. All it takes is some math and some observations about the planet and its relationship to its star.
But how big ( http: / / www.21cnjy.com )is it？How long is its year(the time it takes to orbit around its star)？How much would you weigh if you were there
“TrES 2 is a little bi ( http: / / www.21cnjy.com )gger than Jupiter，has a ‘year’ that is a little less than two and a half days，and is a little more massive than Jupiter，”explains Dunham.
From its mass and r ( http: / / www.21cnjy.com )adius(the distance across the planet) scientists can figure out the density of the planet—whether it is made of rock，gas，or a combination of the two.(TrES 2 is made up mainly of gas.)
They can also work out ( http: / / www.21cnjy.com ) the surface gravity，says Dunham，“You would feel a little more than twice as heavy as on Earth if you were on TrES 2.”
There’s a cat ( http: / / www.21cnjy.com )ch，though.“The temperature is about 1,500 degrees Celsius(2,732 degrees Fahrenheit)，and there is nothing solid to stand on. It isn’t a likely place to look for life，” he says.
Dunham says t ( http: / / www.21cnjy.com )hat to find smaller planets like Earth or Venus，scientists need to send instruments on a mission(使命) to space. NASA scientists are planning one called the Kepler Mission，which could begin in two years.
TrES 2 is in the part ( http: / / www.21cnjy.com )of the sky that the Kepler Mission will study. Since astronomers already know so much about it，they can use it to help make sure their instruments are working.
1．A suitable title for this passage would be________.
A．A Transiting Planet B．A New Planet in Sight
C．The Kepler Mission ( http: / / www.21cnjy.com ) D．Astronomers’ Great Achievements
2．If an astronomer wa ( http: / / www.21cnjy.com )nts to know about a transiting planet，what will he have to do
A．Observe it carefully.
B．Work out the results by doing some math problems.　　21*cnjy*com
C．Find out its relationship to its star.
D．All of the above.
3．What does the under ( http: / / www.21cnjy.com )lined word “them” in Paragraph 3 refer to in the passage
A．transiting plane ( http: / / www.21cnjy.com )ts B．Researchers C．questions D．telescopes
4．Suppose you were ( http: / / www.21cnjy.com ) 56 kilograms on the earth. How much would you weigh if you were on TrES 2
A．Less than 28 kilograms. B．28 kilograms.
C．56 kilograms. D．115 kilograms.
5．Which of the following can be inferred from the passage
A．Astronomers don’t know what TrES 2 is made up of.
B．TrES 2 is the first transiting planet found by scientists on TrES.
C．There’s probably no life existing on TrES 2.
D．Kepler is carrying out its mission on TrES 2.
Ⅴ.书面表达
根据下列提示，写一篇介绍爱因斯坦生平的英语短文。
1．爱因斯坦出生时间(1879.3.14)、地点(Ulm，Germany)；
2．他从小喜欢问问题，到十四岁时就自学完了高等数学，那时就决心成为物理学家，将自己的一生献给科学事业；
3．爱因斯坦家境并不富裕， ( http: / / www.21cnjy.com )但他父母还是设法送他进了一所技术学校，后来又把他送到瑞士的联邦工学院(the Federal Institute of Technology)；
4．1905年获博士学位，就在那时，他开始了研究工作，促进了著名的相对论著作的产生。

2．D　[细节理解题。根据原文第三段最后一句可知选D。]
3．A　[词义猜测题。联系上下文即可看出这句话中的them是指主句中提到的transiting planets。]
4．D　[细节理解题。根据 ( http: / / www.21cnjy.com )原文倒数第四段的“You would feel a little more than twice as heavy as on Earth if you were on TrES 2.”进行计算：56×2＝112，结合a little more than可知D项正确。]
5．C　[推理判断题。根据原文倒数第三段可知 ( http: / / www.21cnjy.com )，由于TrES 2上温度太高以及没有固体的东西可以站立来判断，TrES 2上不太可能有生命存在，故选择C项。而原文的第六段最后一句提到TrES 2主要是由气体组成的，故A项不符合原文描述；由原文第二段第一句话“...it is the second such planet found by scientists...”可知B项错误；根据原文倒数第二段的最后一句可以判断，D项也不正确。]
