【文章內(nèi)容簡(jiǎn)介】 t everything in the universe . A. was kept in order by its own law B. had nothing to do with each other C. happened in an irregular way D. was made by the personal God B “ That’s funny! These fellows in the middle of the plate have died.” Dr Alexander Fleming was talking to another doctor in a laboratory in London. He had been studying some germs（細(xì)菌）that he was growing on a plate. They were very dangerous germs because they caused different kinds of illnesses that could kill people. Dr Fleming found that a mould（ 霉菌 ） had floated in through the window landing on the plate. It had killed some of the germs it had touched. “This certainly looks promising.” Fleming said. “We must grow some of this mould to see if it will kill other germs.” He named the strange mould “penicillin”. It proved to be a killer of many germs. Fifty mice were given deadly germs and then half of them were injected（ 注射 ） with penicillin. The twentyfive untreated mice died, but twentyfour of those lived that had been treated with penicillin. Dr Fleming wrote a report about what he had found out. Hardly anybody took any notice of it. In 1938 Dr Howard Florey, an Australian working in London, read Dr Fleming’s report and was very interested. He found that penicillin was effective in treating blood poisoning in human beings. When World War II broke out, it was not possible to make enough penicillin in England. Dr Florey went to America where he helped to have enormous amounts of this wonderful drug made. It saved the lives of thousands of soldiers, sailors and airmen who would have died from their wounds if the hospitals had not had penicillin. 60. Dr Alexander Fleming .

The word “enormous” means . A. 剩余的 B. 恰當(dāng)?shù)? C. 少許的 D. 巨大的 C Einstein, a great scientist of the age, was almost as strange as his Theory of Relativity. Once, while riding a street car in Berlin, he told the conductor that he had not given him the right change. The conductor counted the change again and found it to be correct, so he handed it to Einstein, saying, “The trouble with you is that you don’t know your figures.” Einstein said that there were only twelve people living who understood his Theory of Relativity although a good many books had been written to explain it. He had nothing but contempt（藐視） for the things most people set their hearts on— for fame and riches（財(cái)富） and luxury（奢華） . He didn’t want money or praise. He made his own happiness out of such simple things as his work and playing the violin and sailing his boat. Einstein’s violin brought him more joy than anything else in life. He said that he often thought in music. 65. The conductor thought Einstein . A. wasn’t good at maths B. had good memory C. was either mad or strange D. liked to make trouble 66. Einstein meant that many people . A. knew his Theory of Relativity well because they could explain it B. had written to have grasped his theory correctly C. pretended to have grasped his abstract theory D. admired him very much 67. The underlined part “set? hearts on” means . A. believe B. have C. love D. hate D Louis Pasteur, the famous French chemist and bacteriologist, invented “pasteurization”. In 1854 Pasteur was made head of the department of science at the University of Lille, and it was there that he made one of his most famous discoveries. Lille was a major center for wine and beermaking, and some o
