题目内容

6．CNN Student News is a ten-minute，commercial-free，daily news program ______ middle and high school classes，______ is available Monday through Friday during the school year．（　　）
A．adapted for； itB．meant for； that
C．intended for； thisD．designed for； which

分析 有线电视新闻网形式新闻是为中学生设计的一个时长十分钟，商业自由的每日新闻节目，该新闻每学年从星期一到星期五都可以收听．

解答 答案：D 句中design作program的后置定语，要用非谓语动词；design与被修饰名词program构成动宾关系，要用表示被动的过去分词；is available Monday through Friday during the school year是修饰program的一个非限制性定语从句；从句缺少主语，要用which来引导．故选D．

点评 过去分词是非谓语动词的一种，用法很灵活，分为简单式done（表示与谓语同时或几乎同时发生的动作）；完成式having been done（表示先于谓语的动作）．学习时，要把握其用法特征：表示被动和完成．同时还要注意区分现在分词和不定式．

16．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（基因构成） 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（潜在的）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（副产品）of technological developments  in the  space  industry!
     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 beings 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．
