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 有線電視新聞網(wǎng)形式新聞是為中學(xué)生設(shè)計的一個時長十分鐘，商業(yè)自由的每日新聞節(jié)目，該新聞每學(xué)年從星期一到星期五都可以收聽．

解答 答案：D 句中design作program的后置定語，要用非謂語動詞；design與被修飾名詞program構(gòu)成動賓關(guān)系，要用表示被動的過去分詞；is available Monday through Friday during the school year是修飾program的一個非限制性定語從句；從句缺少主語，要用which來引導(dǎo)．故選D．

點評 過去分詞是非謂語動詞的一種，用法很靈活，分為簡單式done（表示與謂語同時或幾乎同時發(fā)生的動作）；完成式having been done（表示先于謂語的動作）．學(xué)習(xí)時，要把握其用法特征：表示被動和完成．同時還要注意區(qū)分現(xiàn)在分詞和不定式．

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  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．
51．Why does the author mention the questions in Paragraph l？C
A．To express his doubts．
B．To compare different ideas．
C．To introduce points for discussion．
D．To describe the conditions on Earth．
52．What is the reason for exploring space based on Paragraph 2？A
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 don't like to stay in the same place．
53．The underlined word"spin-offs"in Paragraph 4 probably refers toC
A．survival chances                        B．potential resources
C．unexpected benefits                     D．physical possessions
54．What makes it possible for humans to live on other planets？C
A．Our genetic makeup．
B．Resources on the earth．
C．The adaptive ability of humans．
D．By-products in space exploration．
55．Which of the statements can best sum up the passage？D
A．Space exploration has created many wonders．
B．Space exploration provides the best value for money．
C．Space exploration can benefit science and technology．
D．Space exploration may help us avoid potential problems on Earth．
