　　Why should mankind explore space? Why should money, time and effort be spent exploring and researching something with so few apparent benefits? Why should resources be spent on space rather than on conditions and people on Earth?

　　These are questions that, understandably, are very often asked.

　　Perhaps the best answer lies in our genetic makeup(基因構(gòu)成) as human beings. What drove our ancestors to move from the trees into the plains, and on into all possible areas and environments? The wider the spread of a species, the better its chance of survival. Perhaps the best reason for exploring space is this genetic tendency to expand wherever possible.

　　Nearly every successful civilization has explored, because by doing so, any dangers in surrounding areas can be identified and prepared for. Without knowledge, we may be completely destroyed by the danger. With knowledge, we can lessen its effects.

　　Exploration also allows minerals and other potential (潛在的) resources to be found. Even if we have no immediate need of them, they will perhaps be useful later. Resources may be more than physical possessions. Knowledge or techniques have been acquired through exploration. The techniques may have medical applications which can improve the length or quality of our lives. We have already benefited from other spin-offs including improvements in earthquake prediction, in satellites for weather forecasting and in communications systems. Even non-stick pans and mirrored sunglasses are by-products (副產(chǎn)品) of technological developments in the space, the chance to save ourselves might not exist.

　　While many resources are spent on what seems a small return, the exploration of space allows creative, brave and intelligent members of our species to focus on what may serve to save us. While space may hold many wonders and explanations of how the universe was formed or how it works, it also holds dangers. The danger exists, but knowledge can help human being to survive. Without the ability to reach out across space, the chance to save ourselves might not exist.

　　While Earth is the only planet known to support life, surely the adaptive ability of humans would allow us to live on other planets. It is true that the lifestyle would be different, but human life and cultures have adapted in the past and surely could in the future.

　　71. Why does the author mention the questions in Paragraph1?

　　A. To express his doubts.

　　B. To compare different ideas.

　　C. To introduce points for discussion.

　　D. To describe the conditions on Earth.

　　72. What is the reason for exploring space based on Paragraph2?

　　A. Humans are nature-born to do so.

　　B. Humans have the tendency to fight.

　　C. Humans may find new sources of food.

　　D. Humans dont like to stay in the same place.

　　73. The underlined wordspin-offs in Paragraph 4 probably refers to______.

　　A. survival chances B. potential resources

　　C. unexpected benefits D. physical possessions

　　74. What makes it possible for humans to live on other planets?

　　A. O ur genetic makeup. B. Resources on the earth..

　　C. The adaptive ability of humans. D. By-products in space exploration.

　　75. Which of the statements can best sum un the passage?

　　A. Space exploration has created many wonders.

　　B. Space exploration provided the best value for money.

　　C. Space exploration may help us avoid potential problems on Earth.

　　解析：

　　71. 推理判斷題。答案選C。文章是典型的議論說明文，是提出問題，分析問題的套路。第一段通過提出一系列關(guān)于太空探索利弊的問題引發(fā)討論。并不是真的有這些懷疑，也沒有鮮明的正反觀點(diǎn)，所以AB不對(duì)。D偏差較遠(yuǎn)。

　　72. 主旨題。答案選A。第二段是典型的總分總結(jié)構(gòu)，主旨句在段首段尾。Perhaps the best answer lies in our genetic makeup as human beings. 主要原因在于人類基因。Perhaps the best reason for exploring space is this genetic tendency to expand wherever possible. 而B選項(xiàng)錯(cuò)在fight這個(gè)詞。CD沒提及。
