【文章內容簡介】 organism　into　another ○D.　using　a　viral　enzyme　called　reverse　transcriptase 22.　Rebinant　DNA　technology　has　been　used　in　the　production　of　all　of　the　following　biomolecules　except　___________. ○A.　growth　hormones ○B.　Escherishchia　coli ○C.　interferon ○D.　insulin 23.　Which　of　the　following　is　not　true? ○A.　The　foreign　gene　will　replicate　in　the　bacteria,　but　it　will　not　express　itself　through　transcription　and　translation. ○B.　The　bacterium　Escherishchia　coli　can　be　grown　in　large　amounts　in　synthetic　media. ○C.　Research　continues　in　an　effort　to　find　other　uses　for　this　technology. ○D.　Rebinant　DNA　technology　is　a　recent　development. 24.　Expression　of　a　gene　in　Escherishchia　coli　requires　________. ○A.　the　viral　enzyme　reverse　transcriptase ○B.　the　processes　of　transcription　and　translation ○C.　production　of　insulin　and　other　biomolecules ○D.　that　the　bacteria　be　grown　in　a　synthetic　media 25.　The　term　rebinant　is　used　because　___________. ○A.　by　ligation,　a　rebinant　molecule　is　produced,　which　has　the　capacity　of　replication ○B.　the　technique　requires　the　bination　of　several　types　of　technology ○C.　by　ligation,　a　rebinant　protein　is　produced,　part　of　whose　amino　acids　e　from　different　organism ○D.　Escherishchia　coli　is　a　rebinant　organism Passage　2 Watch　a　baby　between　six　and　nine　months　old,　and　you　will　observe　the　basic　concepts　of　geometry　being　learned.　Once　the　baby　has　mastered　the　idea　that　space　is　three　　dimensional,　it　reaches　out　and　begins　grasping　various　kinds　of　objects.　It　is　then,　from　perhaps　nine　to　fifteen　months,　that　the　concepts　of　sets　and　numbers　are　formed.　So　far,　so　good.　But　now　ominous　(不祥的)　development　takes　place.　The　nerve　fibers　in　the　brain　insulate　(使隔離)　themselves　in　such　a　way　that　the　baby　begins　to　hear　sounds　very　precisely.　Soon　it　picks　up　language,　and　it　is　then　brought　into　direct　munication　with　adults.　From　this　point　on,　it　is　usually　downhill　all　the　way　for　mathematics,　because　the　child　now　bees　exposed　to　all　the　nonsense　words　and　beliefs　of　the　munity　into　which　it　has　been　so　unfortunate　as　to　have　been　born.　Nature　having　done　very　well　by　the　child　now　bees　exposed　to　all　the　nonsense　words　and　beliefs　of　to　this　point,　having　permitted　it　the　luxury　of　thinking　for　itself　for　eighteen　months,　now　abandons　it　to　the　arbitrary　conventions　and　beliefs　of　society.　But　at　least　the　child　knows　something　of　geometry　and　numbers,　and　it　will　always　retain　some　memory　of　the　early　halcyon　(平靜的)　days　no　matter　what　vicissitudes　(變化)　it　may　suffer　later　on.　The　main　reservoir　of　mathematical　talent　in　any　society　is　thus　possessed　by　children　who　are　about　two　years　old.　Children　who　have　just　learned　to　speak　fluently. 26.　What　does　the　passage　mainly　discuss? ○A.　The　impact　of　language　on　mathematics. ○B.　Children39。s　ability　to　learn　languages. ○C.　How　basic　concepts　of　physics　are　learned. ○D.　Mathlearning　strategies　for　babies. 27.　According　to　the　passage,　which　of　following　activities　would　teach　a　baby　geometry? ○A.　Picking　up　a　wooden　block. ○B.　Recognizing　the　number　2. ○C.　Uttering　a　nonsense　word. ○D.　Looking　at　distant　objects. 28.　According　to　the　author,　at　what　age　does　a　child　probably　begin　to　learn　about　sets　and　numbers? ○A.　Six　months. ○B.　Nine　months. ○C.　Fifteen　months. ○D.　Eighteen　months. 29.　The　use　of　the　word　ominous　shows　that　the　author　believe　the　child39。s　_____. ○A.　linguistic　future　is　threatened ○B.　nerves　will　deteriorate ○C.　hearing　will　suffer ○D.　mathematical　ability　all　decline 30.　The　passage　support　which　of　the　following　conclusions? ○A.　The　language　concepts　used　in　early　education　interfere　with　mathematical　reasoning. ○B.　It　is　hopeless　to　try　to　teach　children　mathematics　after　the　age　of　two. ○C.　Language　teaching　should　incorporate　some　mathematical　formulas. ○D.　Preschool　education　should　stress　society39。s　beliefs　and　conventions 第四部分　概括大意　(20分) 給下面一篇文章的每一段概括大意。每一段的主題用一個或幾個單詞表示，空出的詞已給出了第一個字母，請把其余字母補全。 31.　The　Solar　E　 The　sun　is　the　source　of　most　of　the　heat　known　to　us.　As　a　direct　source　of　heat,　the　sun　maintains　life　upon　this　planet,　150　000　000　kilometers　distant.　It　is　also　an　indirect　source　of　heat.　Since　the　earth　is　derived　from　the　sun,　it　is　the　latter　that　we　must　trace　some　of　the　earth39。s　internal　heat　that　reveals　itself　through　volcanoes,　geysers　(噴泉),　and　hot　springs. 32.　Insects　and　Surface　T　 An　insect　is　not　afraid　of　gravity,　but　it　is　in　deadly　fear　of　another　force　of　nature.　This　force　is　called　surface　tension　(張力).　A　man　ing　out　of　a　bath　carries　with　him　a　film　of　water　about　one　fiftieth　of　an　inch　in　thickness.　This　weights　about　a　pound.　A　wet　mouse　has　to　carry　its　own　weight　in　water.　A　wet　fly　has　to　lift　many　times　its　own　weight,　and,　as　everyone　knows,　a　fly　once　wetted　by　water　or　any　other　liquid　is　in　a　very　serious　position　indeed.　An　insect　going　for　a　drink　is　in　as　great　danger　as　a　man　leaning　over　the　edge　of　a　cliff　in　search　of　food.　If　it　once　falls　into　the　grip　of　the　surface　tension　of　the　water　　that　is　to　say,　gets　we
