使浪漫化，使幻想化難句譯注1.Withthecomputer’scapacityforsimulationanddiversekindsoffeedback,allsortsofnewpossibilitiesopenupfortheredesignofcurriculums.[參考譯文]由于計(jì)算機(jī)能進(jìn)行模擬和提供各種反饋，它就為重新設(shè)計(jì)學(xué)校的課程開辟了各種新的可能性。2.Intermsofdrillandpractice,self-pacedcomputer-assistedinstructionenablesthestudenttoadvancerapidly—withoutbeinglimitedbytheconflictingneedsoftheentireclass.[結(jié)構(gòu)簡(jiǎn)析]句子結(jié)構(gòu)為主謂賓補(bǔ)，前后各用一個(gè)介詞（短語(yǔ)），前intermof,后without[參考譯文]就練習(xí)和實(shí)踐來講，借助自行規(guī)定速度的計(jì)算機(jī)輔助的指令使學(xué)生突飛猛進(jìn)而不受全班互相矛盾的需要所限制。3.Withoutromanticizingthemachine,itisclearthatcomputersuniquelychangethepotentialforequippingtoday’scitizensforunprecedentedtasksofthefuture.[結(jié)構(gòu)簡(jiǎn)析]邏輯主語(yǔ)句。句前有一狀語(yǔ)成分，without+分詞+名詞的句型。[參考譯文]不必用浪漫主義的手法來形容計(jì)算機(jī)，我們可清楚看到，它是獨(dú)一無二的改變今天公民的潛力，使他們能承擔(dān)未來的史無前例的任務(wù)。寫作方法與文章大意文章論述了“計(jì)算機(jī)的重要性”，采用一般到具體寫作手法。一開始就提出：作為經(jīng)濟(jì)上先進(jìn)而又脆弱的公民，必須始終不懈地提高技術(shù)素質(zhì)，否則生活水平就會(huì)下降。因?yàn)槲磥韲?guó)際競(jìng)爭(zhēng)取決于技術(shù)，一切部門必須迎合這一要求。具體到工業(yè)和學(xué)校必須使用計(jì)算機(jī)。重點(diǎn)在學(xué)校，因?yàn)樗桥嘤?xùn)新人才的基地。所以三，四，五，七段涉及計(jì)算機(jī)在學(xué)校的種種功能。最后的結(jié)論：人才和計(jì)算機(jī)是決定性因素。答案詳解1.B.工藝技術(shù)。這在第一段就講到“在未來，國(guó)與國(guó)之間的競(jìng)爭(zhēng)越來越以工藝技術(shù)為基礎(chǔ)。盡管石油和其他自然資源仍很重要，但它們不會(huì)再對(duì)一個(gè)國(guó)家的經(jīng)濟(jì)實(shí)力起決定性的作用?！盇.石油。C.自然資源，這兩項(xiàng)不是決定性因素。D.教育。文內(nèi)教育作為改革的一個(gè)方面，其重點(diǎn)是在學(xué)校內(nèi)應(yīng)用計(jì)算機(jī)，來改變教學(xué)質(zhì)量，達(dá)到革新人才的目的。并不是直接參與競(jìng)爭(zhēng)。可參看第2題的答案及譯注。2.B.計(jì)算機(jī)的重要性。整篇文章都顯示了這一點(diǎn)。第三段“工業(yè)上，信息處理和制定必要的改革計(jì)劃以適應(yīng)市場(chǎng)需要意味著越來越多使用計(jì)算機(jī)。學(xué)校緊跟工業(yè)之后……”第四段“計(jì)算機(jī)是一種變化多端，神通廣大的機(jī)器，因?yàn)樗@示千種圖象，發(fā)揮千種功能。而它的真正的革命性可在其相互作用的潛能中看出。有了先進(jìn)的計(jì)算機(jī)，學(xué)習(xí)可以個(gè)別進(jìn)行，速度自行規(guī)定。教師變得更有成效……。”第五段“……由于利用計(jì)算機(jī)，在學(xué)校低年級(jí)就能教授物理學(xué)和高等數(shù)學(xué)概念……?！弊詈笠欢萎孆堻c(diǎn)睛地指出：“計(jì)算機(jī)獨(dú)一無二地改變著那種今天公民能擔(dān)當(dāng)未來空前任務(wù)的潛能……新的競(jìng)爭(zhēng)對(duì)手正在崛起，自由的經(jīng)濟(jì)布局提出挑戰(zhàn)。我們?nèi)绾尾拍茼樌膽?yīng)戰(zhàn)，取決于我們對(duì)人的投資的多寡，取決于我們?cè)趺绰敾鄣貞?yīng)用新技術(shù)的學(xué)習(xí)工具?！彼裕篈.計(jì)算機(jī)知識(shí)。

C.知識(shí)的功能。

D.技術(shù)功能，這三項(xiàng)只是計(jì)算機(jī)重要性中涉及到的一個(gè)方面，不能作為中心思想。3.D.因?yàn)槲覀冎赖囊磺凶兊藐惻f。第二段頭幾句話“我們決不能吃老本，當(dāng)今的競(jìng)爭(zhēng)使我們的大部分知識(shí)變得陳舊，非加以革新不可。對(duì)每個(gè)人來說，他們將慣常從事某幾種職業(yè)，并且非繼續(xù)學(xué)習(xí)進(jìn)修和從新接受訓(xùn)練不可……?！倍颊f明進(jìn)修學(xué)習(xí)的原因。A.人們要做更多工作。文內(nèi)沒有提到。

B.人們要到達(dá)非同一般的教育水平。這是目的，不是原因。

C.人們不能吃老本。這話并沒有完全講清楚全部原因。4.A.靈活多變。Proteus一詞，原義是指希臘神話中變幻無常的海神，普羅狄斯，他可以隨心所欲邊成各種形狀。這里指靈活多變。PassageForty--Eight(TheRelationshipbetweenBrainProcesswithMentalExperience)
