　　If the population of the earth goes on increasing at its present rate, there will eventually not be enough resources left to sustain life on the planet. By the middle of the 21st century, if present trends continue, we will have used up all the oil that drives our cars, for example. Even if scientists develop new ways of feeding the human race, the crowded conditions on earth will make it necessary for us to look for open space somewhere else. But none of the other planets in our solar system are capable of supporting life at present. One possible solution to the problem, however, has recently been suggested by an American scientist, Professor Carl Sagan.
　　Sagan believes that before the earth's resources are completely exhausted it will be possible to change the atmosphere of Venus (金星) and so create a new world almost as large as earth itself. The difficulty is that Venus is much hotter than the earth and there is only a tiny amount of water there.
　　Sagan proposes that algae (藻类) organisms, which can live in extremely hot or cold atmospheres and at the same time produce oxygen, should be bred in conditions similar to those on Venus. As soon as this has been done, the algae will be placed in small rockets. Spaceships will then fly to Venus and fire the rockets into the atmosphere. In a fairly short time, the algae will break down the carbon dioxide into oxygen and carbon.
　　When the algae have done their work, the atmosphere will become cooler, but before man can set foot on Venus it will be necessary for the oxygen to produce rain. The surface of the planet will still be too hot for men to land on it but the rain will eventually fall and in a few years something like earth will be reproduced on Venus.
　　21. In the long run, the most difficult problem caused by population growth on earth will probably be the lack of______.
　　A. food B. oil
　　C. space D. resources
　　22. Carl Sagan believes that Venus might be colonized from earth because______.
　　A. it might be possible to change its atmosphere
　　B. its atmosphere is the same as the earth's
　　C. there is a good supply of water on Venus
　　D. the days on Venus are long enough
　　23. On Venus there is a lot of______.
　　A. water B. carbon dioxide
　　C. carbon monoxide D. oxygen
　　24. Algae are plants that can______.
　　A. live in very hot temperatures B. live in very cold temperatures
　　C. manufacture oxygen D. all of the above
　　25. Man can eventually land on Venus only when______.
　　A. the algae have done their work B. the atmosphere becomes cooler
　　C. there is oxygen D. it rains there

　　It is doing something better than other people that makes us unique. Yet a surprising number of people still see individuality as a surface thing. They wear bright clothes, dye their hair strange colors and decorate their skin with tattoos (文身) to make some kind of social statement.
　　The whole purpose of individuality is excellence. The people who comprehend the simple principle of being unique through performance make our entire political and economic system work. Those who invent, who improve, who know more about a subject than other people do, and who take something that doesn't work and make it work—these people are the very soul of capitalism.
　　Charles Kettering didn't like the idea of cranking a car to make it start, so he invented the electric starter. Henry Ford figured out the assembly-line technique and made it possible to mass-produce automobiles. Lewis Waterman saw no need to go on dipping a pen into an inkwell, so he put the ink into the pen. George Westinghouse told the world how to stop a train, and Elisha Otis, inventor of the elevator, indirectly created the city skyline. These people understood that individualism means working at the top of one's capacity.
　　Fortunately, enough Americans have been inspired to do something with their uniqueness that we have developed in less than three centuries from a frontier outpost into not only a country of freedom but a country strong enough to protect that freedom. These people prized the notions of individuality and excellence above all things and thus kept the great machine functioning. The ones with the purple hair and the horrorable jewelry are just along for the ride, trying to be "different" and not knowing how to go about it.
　　The student who earns A's on his report card has grasped the idea and has found the real meaning of individuality. So has the youngster who has designed his own spaceship, who paints pictures of the world around him, or who can name all the states and their capitals. According to the author unique individuals are persons who______.
　　A. do something better than other people
　　B. know more about a subject than other people
　　C. excel others in work
　　D. all of the above
　　People who regard individuality as a surface thing always do the following EXCEPT
　　A. wearing bright clothes B. coloring their hair
　　C. doing better than others D. decorating their skin with tattoos

　　It can be inferred from the passage that______.
　　A. the real secret to being unique lies in our excellent work
　　B. if we want to be different we'd gain more profit
　　C the student who earns A's on the report card has not grasped the real meaning of
　　individuality D. all Americans work miracles In the writer's opinion who has understood the sense of individuality?
　　A. The youngster who designed his own spaceship.
　　B. The youngster who painted worthy pictures.
