Stephen William Hawking was born on January 8th, 1942 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. At eleven Stephen went to St. Albans School, and then on to University College, Oxford, his father’s old college. Stephen wanted to do math, although his father would have preferred medicine. Math was not available at University College, so he did physics instead.
Stephen then went on to Cambridge to do research in Cosmology (宇宙论). After gaining his Ph.D. (哲学博士) 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 Math and Theoretical Physics (理论物理), and since 1979 has held the post of Lucasian Professor of math.
Stephen Hawking has worked on the basic laws which rule the universe. With Roger Penrose he showed that Einstein’s General Theory of Relativity implied space and time would have a beginning in the Big Bang and an end in black holes. These results show it was necessary to unify (统一) General Relativity with Quantum Theory (量子论). One result of such a unification that he discovered was that black holes should not be completely black, but should give off radiation and disappear in the end.
56. Which of the following is NOT suitable for describing Stephen Hawking?
A. He once studied at the same college that his father studied at.
B. At one time he did research in Cosmology in Oxford.
C. He preferred math to medicine at college.
D. He contributed to the unification of General Theory of Relativity and Quantum Theory.
57. The underlined word “available” in the first paragraph probably means “________”.
A. able to be had B. allowed to study C. easy to understand D. limited to learn
58. Why did Stephen Hawking’s parents move to Oxford from North London?
A. Because they liked it better than North London.
B. Because there was a world-famous university there.
C. Because they were tired of living in North London.
D. Because it was safer to give birth to a bay in Oxford.
59. Which of the following would be the best title for the passage?
A. Einstein and Stephen Hawking
B. Big Bang, a great theory
C. Stephen Hawking, a great British scientist
D. The unification of two theories

轻巧夺冠周测月考直通名校系列答案Even plants can run a fever, especially when they're under attack by insects or disease. But unlike human, plants can have their temperature taken from 3,000 feet away—straight up. A decade ago, adopting the infrared(红外线)scanning technology developed for military purposes and other satellites, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress. The goal was to let farmers precisely target pesticide(杀虫剂)spraying rather than rain poison on a whole field, which invariably includes plants that don't have pest problems.
Even better, Paley's Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flown at 3,000 feet at night, an infrared scanner measured the heat emitted by crops. The data were transformed into a colourcoded map showing where plants were running “fevers”. Farmers could then spotspray, using 50 to 70 percent less pesticide than they otherwise would.
The bad news is that Paley's company closed down in 1984, after only three years. Farmers resisted the new technology and longterm backers were hard to find. But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation. Agriculture experts have no doubt the technology works. “This technique can be used on 75 percent of agricultural land in the United States, ” says George Oerther of Texas A & M. Ray Jackson, who recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade. But only if Paley finds the financial backing which he failed to obtain 10 years ago.

When I was three years old, my parents discovered I was totally deaf. But instead of sending me to a school for the deaf, they decided to “mainstream” me. All of my peers and teachers world have normal hearing.
I was the only deaf child at Blue Creel Elementary School. From almost the first day there, the other kids made fun of me mainly because of my hearing aid and the way I talked. And I also had difficulty with most of my school work.
When the other kids made fun of me, I was sure that I was a bad person. I saw myself as a boy who wasn’t smart enough to keep up with the class.
Mrs. Jordan, my 5th grade teacher, changed all of that with a simple three-word phrase.
One morning, she asked the class a question. I read her lips from my front-row seat and immediately raised my hand because I was sure I had the right answer. But when she called on me, I was afraid. Here was an opportunity to impress the powerful teacher and show her I was worthy of her love. Maybe even impress my classmates a little. I didn’t want to blow it. despite my fears, I took a deep breath and answered Mrs. Jordan’s question.
I will never forget what happened next. Mrs. Jordan enthusiastically slammed （跺动）her right foot on the floor and turned her tight hand around in full circle until it pointed directly at me. With sparking eyes and a wide smile she cried, “THAT’S RIGHT STEPHEN!”
For the first time in my young life, I was a star. I sat a little taller in my chair.
From that day forward, my grades and speech improved greatly. My popularity among my peers increased. It was all because Mrs. Jordan believed in me and wasn’t afraid to express it. “THAT’S RIGHT STEPHEN!”
