问答题 56. {{U}}When you are in the business of sending spacecraft to other planets, it is probably wise to do everything you can m keep your space-probes sterile (无菌的){{/U}}. NASA, America's space agency, certainly does so. After all, you would not want hugs from one planet to contaminate another where they might possibly thrive. But according to Curt Mileikowsky, of the Royal Institute of Technology in Stockholm, this may already have happened naturally billions of years ago when the solar sys- tem was young. For Dr Mileikowsky has taken a century-old idea called panspermia (有生源说), and shown that it is plausible. 57. {{U}}Panspermia is the theory that life does not start independently on each planet that has it (assuming that other planets do). Rather, it hops from place to place, "infecting" new worlds as it goes{{/U}}. Supported by experts in biology, geology and celestial mechanics, Dr Mileikowsky argued to the American Astronomical Society meeting in Atlanta that this is not as outlandish as it sounds. 58. {{U}}Bungling (笨手笨脚) space organizations apart, the only mode of travel open to microbes seems to be meteorites (流星). Most of these are small bits of junk from the asteroid (小行星) belt that have gone off course{{/U}}. But some are rocks that have been flung into space from the surfaces of planets as a result of those planets having been struck by even larger bits of rock--decent-sized asteroids or comets. 59. {{U}}If there is life on such a planet, microscopic forms of it will probably live deep in- side rocks, as they do on earth. The acceleration of lift-off would not kill something that size{{/U}}. 60. {{U}}If a rock is large enough, the heat generated as it is thrown clear will be negligible except at its surface--where, ii anything, melting may even produce an airtight skin to protect any microbes deeper down from the unpleasant vacuum of space{{/U}}.

问答题{{B}}Directions:{{/B}} Read the following passage carefully and then translate each underlined part into Chinese. 71. {{U}}Vacations were once the prerogative of the privileged few, even as late as the 19th century. Now they are considered the right of all, except for such unfotrunate masses as, for example, the bulk of puplation in certain countries, for whom life, save for sleep and brief periods of rest, is uniterrupted toil.{{/U}} Vacations are more necessary now than before because today the average life is less well-rounded and has become increasingly compartmentalized. 72. {{U}}I suppose the idea of vacations, as we conceive it, must be incomprehensible to primitive peoples. Rest of some kind has of course always been a part of the rhythm of human life, but earlier ages did not find it necessary to organize it in the way that modern man has done. Holidays and feast days were sufficient.{{/U}} With modern man's increasing tensions, with the stultifying quality of so much of his work, this break in the year's routine became steadily more necessary. 73. {{U}}Vacations became mandatory for the purpose of renewal and repair. And so it came about that in the United States, the most self-indulgent of nations, the most tense and compartmentalized, vacations have come to take a predominant place in domestic conversation.{{/U}}

Your essay should meet the requirements below. 1) Elaborate your impressions on the story told, and 2) point out its implications in our life. One summer my wife Chris and I were invited by friends to row down the Colorado River in a boat. Our expedition included many highly successful people--the kind who have staffs to take care of life's daily work. But in the wilder rapids, all of us naturally set aside any pretenses and put out backs into every stroke to keep the boat from tumbling over. At each night's encampment, we all hauled supplies and cleaned dishes. After only two days in the river, people accustomed t-o being spoiled and indulged had become a team, working together to cope with the unpredictable twists and turns of the river. I believe that in life--as well as on boat trips-teamwork will make all our journeys successful ones. The rhythms of teamwork have been the rhythms of my life...
