  Passage 4

  Should the United States support a Man In Spaceprogram? Opponents and proponents present strong arguments on both sides.

  The opponents point out how enormously expensive manned space operations are: Every shuttle flight costs taxpayers about $500 million, and the anticipated bill for the international space station is $35 billion-$40 billion.They also think that the returns form such space investments so far do not justify the expense.They suspect that much of the space testing of new materials and purer crystals could be performed on Earth at a much lower cost, either through automated systems, on less-expensive unmanned rockets, or even in laboratories.They believe it is reckless to spend such enormous sums of money in space for an uncertain return, when there are so many unmet needs here on Earth.

  The proponents of manned space programs have difficulty countering these strong arguments.However, they point out that since the space shuttle now exists we might as well make use of it.They believe that new materials created in the space environment may prove extremely useful and that the perfect crystals which cannot be made in Earth's gravity will allow us to understand the molecular structure of viruses.As a result, we may be able to create powerful new drugs, perhaps overcoming critical diseases, even AIDS.They also argue that the space station represents the first truly international endeavor on a great scale and that it will promote cooperation and understanding between nations and help eliminate future wars.

  Taking a broader view, there is no doubt that exploration of new lands and conquests of new frontiers have always been creative forces throughout the history of humanity and have promoted the advancement of knowledge and culture.In 1993, when Congress saved the international space station from being abandoned, a decisive event occurred in man's conquest of space.This critical act may deeply affect humanity's future.It was the discovery of the New World that gave Western civilization the impetus for the explosive growth in science and technology that took place during the succeeding centuries.Exploring space and colonizing other planets is not an option.It is a necessity if humanity is to evolve and not become an inactive species with no room and no incentive for further development.

  C.Cooperation between nations may be promoted.

  D.Population on earth may be reduced.

  59.Which of the following statements is NOT true?

  A.The Man is Spaceprogram brings about a lot of arguments.

  B.It is easy for supporters of the program to convince their opponents of its necessity.

  C.Throughout the history of humanity, people always like to explore new lands and conquer new frontiers.

  D.It is necessary for people to explore space and colonize other planets if humanity is to evolve.
