【正文】 times. How long can humans live? Human brains were known to decide the final death. Cells are the basic units of all living things, and until recently, scientists were sure that the life of cells could not go much beyond l20 years because the basic materials of cells, such as those of brain cells, would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will be able to take medicine to repair their ans. The medicine, made up of the basic building materials of life, will build new brain cells, heart cells, and so on — in much the same way our bodies make new skin cells to take the place of old ones. It is exciting to imaging that the advance in technology may be changing the most basic condition of human existence, but many technical problems still must be cleared up on the way to this wonderful future. 28.

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 (宇宙論 ). After gaining his .（哲學博士） 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 (理論物理 ), 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（統(tǒng)一） General Relativity with Quantum Theory （量子論） . One result of such a unification that he discovered was that black holes should not be pletely black, but should give off radiation and disappear in the end. 32. 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. He preferred math to medicine at college. C. At one time he did research in Cosmology in Oxford. D. He contributed to the unification of General Theory of Relativity and Quantum Theory. 33. The underlined word “ available” in the first paragraph probably means “ ____” . A. limited to learn B. allowed to study C. easy to understand D. able to be had 34. 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 worldfamous university there. C. Because it was safer to give birth to a baby in Oxford. D. Because they were tired of living in North London. 35. Which of the following would be the best title for the passage? A. Stephen Hawking, a great British scientist B. Big Bang, a great theory C. Einstein and Stephen Hawking D. The unification of two theories 第二節(jié) （共 5 小題；每小題 2 分，滿分 10 分） 根據(jù)短文內(nèi)容，從短文后的選項中選出能填入空白處的最佳選項。in. It had been very 41 three days for me with lots of meetings.
