But　even　while　enjoying　the　results　of　technical　progress,　he　must　defend　the　primacy　(第一位)and　autonomy　of　pure　knowledge.　Knowledge　sought　directly　for　its　practical　applications　will　have　immediate　and　foreseeable　success,　but　not　the　kind　of　important　result　whose　revolutionary　scope　is　in　large　part　unforeseen,　except　by　the　imagination　of　the　Utopians　(空想家).　Let　me　recall　a　wellknown　example.　If　the　Greek　mathematicians　had　not　applied　themselves　to　the　investigation　of　conic　(圓椎形的)　sections,　zealously　and　without　the　least　suspicion　that　it　might　someday　be　useful,　it　would　not　have　been　possible　centuries　later　to　navigate　far　from　shore.　The　first　men　to　study　the　nature　of　electricity　could　not　imagine　that　their　experiments,　carried　on　because　of　mere　intellectual　curiosity,　would　eventually　lead　to　modern　electrical　technology,　without　which　we　can　scarcely　conceive　of　contemporary　life.　Pure　knowledge　is　valuable　for　its　own　sake,　because　the　human　spirit　cannot　resign　itself　to　ignorance.　But,　in　addition,　it　is　the　foundation　for　practical　results　that　would　not　have　been　reached　if　this　knowledge　had　not　been　sought　disinterestedly　(公正無私地). 41.　The　most　important　advances　made　by　mankind　e　from　__________. ○A.　technical　applications ○B.　apparently　useless　information ○C.　the　natural　sciences ○D.　philosophy 42.　In　the　paragraph　the　follows　this　passage,　we　may　expect　the　author　to　discuss　________. ○A.　the　value　of　technical　research ○B.　the　value　of　pure　research ○C.　philosophy ○D.　unforeseen　discoveries 43.　The　author　points　out　that　the　Greeks　who　studied　conic　sections　__________. ○A.　were　mathematicians ○B.　were　interested　in　navigation ○C.　were　unaware　of　the　value　of　their　studies ○D.　worked　with　electricity 44.　The　title　below　that　best　expresses　the　ideas　of　passage　is　__________. ○A.　A　Little　Learning　Is　a　Dangerous　Thing ○B.　Man39。s　Distinguishing　Characteristics ○C.　Learning　for　its　Own　Sake ○D.　The　Difference　between　Science　and　Philosophy 45.　The　practical　scientist　__________. ○A.　knows　the　value　of　what　he　will　discover ○B.　is　interested　in　the　unknown ○C.　knows　that　the　world　exists ○D.　conceives　of　contemporary　life 第六部分　完形填空　(30分) 根據短文在空白處填上適當的單詞，該單詞的第一個字母已經給出。 Electricity　is　such　a　part　of　our　everyday　lives　and　so　much　taken　for　g____46_____　nowadays　that　we　rarely　think　twice　when　s____47____　on　the　light　or　turn　on　the　radio.　At　night,　roads　are　brightly　l____48_____,　enabling　people　and　t____49____　to　move　freely.　Neon　(霓虹)　lighting　used　in　a　s_____50____　has　bee　part　of　the　character　of　every　modern　city.　In　the　home,　many　laboursaving　devices　are　p_____51_____　by　electricity.
