SectionIUseofEnglish答案解析：1.B.本題考查動(dòng)詞，后面的賓語(yǔ)是“thefruit-flyexperimentsdescribed…”，suppose表示“假設(shè)”，observe表示“觀察”，image表示“想象”，Consider“考慮”，代入文中表示“考慮已經(jīng)被描述出來(lái)的實(shí)驗(yàn)”，符合語(yǔ)境。2.A.本題考查動(dòng)詞短語(yǔ)，happento(碰巧)，fearto(唯恐…)，bethreatenedto被恐嚇…。tendtodo表示“有…傾向，往往…”，代入文中表示比較聰明的果蠅往往壽命較短。3.D.本題考查形容詞，lighter更輕的，thinner更瘦的，stabler更穩(wěn)定的，dimmer比較暗淡的，本句是前一句推出的結(jié)論，即由“果蠅越聰明壽命越短”推出“燈泡越暗使用時(shí)間越長(zhǎng)”。4.B.本題考查名詞。由前半句“燈泡越暗使用時(shí)間越長(zhǎng)”推出“這是不特別亮的燈泡的一個(gè)優(yōu)點(diǎn)”。tendency傾向，advantage優(yōu)勢(shì)，inclination傾向，priority優(yōu)先權(quán)。5.C.本題考查動(dòng)詞短語(yǔ)，turnsout證明是，insiston堅(jiān)持，sumup總結(jié)，putforward提出。6.A.本題考查介詞，off表示離開(kāi)。代入文中表示離開(kāi)起點(diǎn)時(shí)。7.D.incredible難以置信的，spontaneous自發(fā)的，inevitable不可避免的，gradual漸進(jìn)的。學(xué)習(xí)是一個(gè)漸進(jìn)的過(guò)程，所以選gradual.8.C.本文的主旨是智力需要昂貴的代價(jià)。大量的物種會(huì)學(xué)習(xí)，但它們首先學(xué)會(huì)的是知道什么時(shí)候停止學(xué)習(xí)，與上文的例子燈泡呼應(yīng)。四個(gè)選項(xiàng)中，fight表示斗爭(zhēng)，doubt表示懷疑，stop表示停止，think表示思考，正確答案為C9.B.本題考查形容詞，修飾intelligence。invisible看不見(jiàn)的，indefinite不確定的，這兩個(gè)選項(xiàng)意思不符合，排除。different不同的，limited有限的。因?yàn)樗形锓N的智力都是有限的，所以limited符合文意。10.D.castaglancebackward“回顧”，固定搭配。11.D.feature特征，influence影響，result結(jié)果，cost代價(jià)。Cost“代價(jià)”與文中“事實(shí)證明，智力是要付出代價(jià)”相呼應(yīng)。12.B.本題考查介詞，onthemindof“為…著想”，bythemind“通過(guò)思考”，outside和across不與mind的搭配。13.C.本題考查動(dòng)詞，與之搭配的賓語(yǔ)是experiments，選項(xiàng)中perform能與experiments搭配，表示“做實(shí)驗(yàn)”。deliver遞送，carry運(yùn)送，apply應(yīng)用。14.D.前一句提到experiments，本句提到一個(gè)具體的實(shí)驗(yàn)，所以選forinstance例如。bychance偶然，incontrast相反，asusual照常。15.A.由后半句中theywouldtestusto可推測(cè)本句使用了虛擬語(yǔ)氣，選項(xiàng)中if可以引導(dǎo)虛擬條件句。unless除非，as正如，lest唯恐。16.C.本題考查動(dòng)詞。所填動(dòng)詞表明實(shí)驗(yàn)的目的，并且所填動(dòng)詞的賓語(yǔ)是limitsofourpatience,ourfaithfulness,ourmemoryforterrain，選項(xiàng)中“determine確定”符合題意，并與下文的decide相呼應(yīng)。moderate適中的，overcome克服，reach達(dá)到。17.B.本題考查介詞，四個(gè)選項(xiàng)中for表示表示目的，這個(gè)句子的正常句序是intelligenceinhumansisreallyforwhat.18.A.本題考查邏輯關(guān)系。這個(gè)句子位于段末，顯然起到總結(jié)性的作用。四個(gè)選項(xiàng)中，Aboveall最重要，Afterall畢竟，However然而，Otherwise否則，故選Aboveall。19.A.本題考查形容詞，修飾question。fundamental基本的，comprehensive全面的，equivalent相等的，hostile敵對(duì)的。由句后問(wèn)題的內(nèi)容可推出這是一個(gè)最基本和重要的問(wèn)題，所以選fundamental。20.C.本題考查副詞。空前說(shuō)“想研究這個(gè)問(wèn)題”，空后說(shuō)“結(jié)果還不確定”。四個(gè)選項(xiàng)中，Byaccident“偶然”，Intime“及時(shí)”，Sofar“到目前為止”，Betterstill“更好的是”，只有Sofar符合語(yǔ)意。全文翻譯：對(duì)動(dòng)物智力的研究總是讓我們思考人類(lèi)到底有多聰明。參考下卡爾齊默周二發(fā)表在科學(xué)時(shí)代刊物上的文章所描述的果蠅試驗(yàn)。有些果蠅比普通果蠅聰明，但是壽命較短。這表明暗淡的燈泡使用時(shí)間更長(zhǎng)，也表明暗淡是燈泡的一個(gè)優(yōu)勢(shì)。事實(shí)證明，智力是要付出昂貴的代價(jià)。它需要更高的給養(yǎng)、消耗更多的燃料，因?yàn)橹橇σ揽康氖菍W(xué)習(xí)(一個(gè)循序漸進(jìn)的過(guò)程)而不是一種本能，所以離開(kāi)起點(diǎn)時(shí)緩慢。許多其他的物種也有學(xué)習(xí)能力，很顯然他們學(xué)到的東西之一就是知道何時(shí)停止。有限的智力是否有適應(yīng)值呢?這也是此項(xiàng)研究的課題。我對(duì)此很感興趣。這個(gè)試驗(yàn)不是去回顧那些被我們劃為低智商的物種，而是含蓄在問(wèn)我們自己智力的真正代價(jià)是什么。我們所遇到的每種動(dòng)物的想法。對(duì)動(dòng)物智力的研究也讓我想，如果動(dòng)物有機(jī)會(huì)的話，他們會(huì)對(duì)人類(lèi)作什么樣的實(shí)驗(yàn)。比如說(shuō)，每只有主人的貓都在進(jìn)行一個(gè)小型的操作性條件反射研究。我們認(rèn)為如果動(dòng)物也能進(jìn)行試驗(yàn)的話，他們會(huì)測(cè)定我們的忍耐度，忠誠(chéng)度，以及對(duì)地形的記憶力。他們會(huì)試圖判定人類(lèi)智力的實(shí)際用處，而不僅僅是判定人類(lèi)智力的高低。最重要的是他們希望研究一個(gè)最基本的問(wèn)題：人類(lèi)是否真正意識(shí)到了自己所生存的世界?對(duì)此，目前仍無(wú)定論。SectionIIReadingCompreh
