Some geologists，however，on the basis of observations concerning mantle xenoliths， argue that the mantle is not layered，but that heterogeneity is created by fluids rich in "incompatible elements" （elements tending toward liquid rather than solid state）percolating upward and transforming portions of the upper mantle irregularly，according to the vagaries of the fluids‘ pathways. （4+）但是，某些地質(zhì)學(xué)家，以對(duì)地幔捕虜巖體（xenolith）所作的觀察為依據(jù)，指出地幔并非是分層排列的，相反，地幔的異質(zhì)性是由那些富含“不相容成分”的流質(zhì)構(gòu)成的，這些成分趨向于流體而非固體的狀態(tài)，自下而上滲透擴(kuò)散，并依照這些流質(zhì)流向的任意性，不規(guī)則地將上部地幔的某些部分予以改變。

The isotopic composition of lead often varies from one source of common copper ore to another，with variations exceeding the measurement error；and preliminary studies indicate virtually uniform is topic composition of the lead from a single copper-ore source. （4）鉛的同位素構(gòu)成經(jīng)常在一種普通銅礦石來(lái)源與另一種銅礦石來(lái)源之間存在差異，其差異程度超出測(cè)量誤差；而最初的研究表明，對(duì)于來(lái)自單獨(dú)一個(gè)銅礦石來(lái)源的鉛來(lái)說(shuō)，其同位素構(gòu)成幾乎是毫無(wú)二致的。
難句類型：復(fù)雜修飾、插入語(yǔ)、專業(yè)抽象詞解釋：本句是一個(gè)怪異的現(xiàn)象的典型例子：句子的結(jié)構(gòu)談不上復(fù)雜，所用單詞也不難，但是除非讀者有理工科的科研（是材料科學(xué)的科研）背景，否則句子雖然能夠得讀下來(lái)，但是卻搞不清句子說(shuō)的是什么意思。首先，句子中出現(xiàn)的一些詞匯雖然也都比較常見，但是在理科文章中出現(xiàn)，就有了專有名詞的意味，同時(shí)還帶有很抽象的學(xué)術(shù)含義，筆者稱之為專業(yè)抽象詞，如isotopic composition；source；variation；measurement error；preliminary study等。認(rèn)識(shí)這些單詞，并不意味著懂得它們?cè)谖恼碌囊饬x和作用。比如說(shuō)measurement error，大家都可以望文生義地理解成測(cè)量錯(cuò)誤、測(cè)量誤差，但是在對(duì)文章的閱讀中這種字面上的理解是遠(yuǎn)遠(yuǎn)不夠的。其實(shí)此處強(qiáng)調(diào)的并不是測(cè)量中出現(xiàn)的錯(cuò)誤和毛病，而是指那些每次測(cè)量都會(huì)發(fā)生的、永遠(yuǎn)也無(wú)法避免的、在測(cè)量值和實(shí)際值之間的正常的差異。因此，本句話的真實(shí)含義也難以理解。句子只是羅列了一堆事實(shí)，而作者真正想說(shuō)的意思是什么呢？其實(shí)variations exceeding the measurement error的言外之意是這些不同variations是真正有意義的不同，而不是試驗(yàn)的誤差；那么不同礦源的銅礦的鉛同位素成分真的不同，相同的礦源的鉛同位素幾乎相同，就意味著我們可以通過(guò)測(cè)量鉛同位素的成分來(lái)確定銅礦的礦源（挖掘地）。

Some geologists，however，on the basis of observations concerning mantle xenoliths， argue that the mantle is not layered，but that heterogeneity is created by fluids rich in "incompatible elements" （elements tending toward liquid rather than solid state）percolating upward and transforming portions of the upper mantle irregularly，according to the vagaries of the fluids‘ pathways. （4+）但是，某些地質(zhì)學(xué)家，以對(duì)地幔捕虜巖體（xenolith）所作的觀察為依據(jù)，指出地幔并非是分層排列的，相反，地幔的異質(zhì)性是由那些富含“不相容成分”的流質(zhì)構(gòu)成的，這些成分趨向于流體而非固體的狀態(tài)，自下而上滲透擴(kuò)散，并依照這些流質(zhì)流向的任意性，不規(guī)則地將上部地幔的某些部分予以改變。

62. Many critics of Family Bronte‘s novel Wuthering Heights see its second part as a counterpoint that comments on，if it does not reverse，the first part，where a "romantic" reading receives more confirmation. （5） 研究艾米麗。勃朗特（Emily Bronte）小說(shuō)《呼嘯山莊》（Wuthering Heights）的許多文學(xué)評(píng)論家，將小說(shuō)的第二部分視作一種對(duì)比物，即使沒(méi)有將第一部分予以逆轉(zhuǎn)的話，也是在對(duì)第一部分作出一種詮釋評(píng)判，而在小說(shuō)第一部分中，一種“浪漫的”的讀解能獲得更為充分的確證。
難句類型：復(fù)雜修飾、插入語(yǔ)解釋：上面的翻譯中為了符合中文習(xí)慣不得不把修飾the first part的where引導(dǎo)的定語(yǔ)從句翻譯到中括號(hào)以外。本句主要難在兩個(gè)地方，一個(gè)是插入語(yǔ)if it does not reverse如何理解，另一個(gè)是counterpoint的意思是什么。產(chǎn)生，插入語(yǔ)的位置比較討厭，把comments on the first part這樣一個(gè)連貫的說(shuō)法割成兩段，增加了閱讀的難度。而且它的意思容易理解錯(cuò)；if既可以理解成如果的意思，也可以理解成即使的意思。如果理解成即使的意思，則上下文的意思則要理解成即使不反對(duì)第一部分，也要給予第一部分一個(gè)負(fù)面的評(píng)論。然而此處不能這樣理解，因?yàn)閠hat之前的counterpoint的意思不是相反、對(duì)立，而是指和諧的組成部分的意思。這個(gè)詞來(lái)源于一個(gè)音樂(lè)術(shù)語(yǔ)，指音樂(lè)中的對(duì)位法、旋律配合，引伸為形容兩個(gè)不同的東西彼此和諧一致，同義詞是harmony.因此文中的if it does not reverse的意思是假如不反對(duì)第一部分，則是與第一部分和諧一致的評(píng)論的意思。這種情況下，插入語(yǔ)純屬?gòu)U話。

Granted that the presence of these elements need not argue an authorial awareness of novelistic construction comparable to that of Henry James， their presence does（15） encourage attempts to unify the novel’s heterogeneous parts. （4+）誠(chéng)然，這些因素的存在并不能證明作者對(duì)小說(shuō)架構(gòu)的意識(shí)可與亨利。詹姆斯（Henry James）的那種意識(shí)相比擬；然則，任何力圖將小說(shuō)所有形形色色的因素統(tǒng)一起來(lái)的做法，在某種程度上注定是無(wú)法令人信服的。 Granted that：大家都統(tǒng)一、當(dāng)然，表讓步，=admitted ， of course.難句類型：復(fù)雜修飾、抽象詞解釋：本句的結(jié)構(gòu)固然復(fù)雜，但造成的閱讀難度的，主要還是對(duì)一些抽象詞的理解。正面是對(duì)一些關(guān)鍵詞匯的解釋： ◎大寶考研版權(quán)所有，拒絕轉(zhuǎn)載◎SoDMLxw4Vi Granted that出現(xiàn)在句首，其意思是大家都同意、當(dāng)然，實(shí)際上是一種讓步語(yǔ)氣，等于admitted，of course. ◎大寶考研版權(quán)所有，拒絕轉(zhuǎn)載◎t1DGV8GDSK Need not argue中的argue在此不是表示常用的那個(gè)辯論、爭(zhēng)論的意思，而是表示意味著或證實(shí)的意思，其同義詞是maintain或prove.Camparable的詞義有兩個(gè)，除了讀者熟悉的that can be compared之外，還有一個(gè)意思是worthy of comparison，其同義詞是as good as.本文中用的是后面的那個(gè)意思，對(duì)于這個(gè)詞義的理解，后面的第18題考到了。

64. This is not because such an interpretation necessarily stiffens into a thesis（although rigidity in any interpretation of this or of any novel is always a danger），but because Wuthering Heights has recalcitrant elements of undeniable power that，ultimately，resist inclusion in an all-encompassing interpretation. （5） 這倒不是因?yàn)檫@樣的一種解釋必定會(huì)僵化成為一個(gè)命題（盡管對(duì)這部或任何一部小說(shuō)的解釋中，僵化死板總是一種危險(xiǎn)），而是因?yàn)椤逗魢[山莊》擁有一些極難駕御的因素，以其無(wú)可辯駁的力度，最終拒絕被囿于一個(gè)囊括無(wú)遺的解釋中。
難句類型：復(fù)雜修飾、插入語(yǔ)、抽象詞解釋：本句的兩個(gè)插入語(yǔ)雖然有一些干擾性，但是最為主要的難點(diǎn)在于成批出現(xiàn)的抽象詞，如interpretation/necessarily/stiffen/thesis/rigidity/recalcitrant/element/undeniable/power/ultimately/resist/inclusion/all-encompassing等。據(jù)筆者估測(cè)，對(duì)于初學(xué)GRE或GMAT的學(xué)習(xí)者而言，在一句話中出現(xiàn)了三個(gè)心上的抽象詞就會(huì)使閱讀理解造成障礙，而這句話中出現(xiàn)了十三個(gè)這樣的單詞，讀不懂也不足為怪。

65. The isotopic composition of lead often varies from one source of common copper ore to another，with variations exceeding the measurement error；and preliminary studies indicate virtually uniform is topic composition of the lead from a single copper-ore source. （4）鉛的同位素構(gòu)成經(jīng)常在一種普通銅礦石來(lái)源與另一種銅礦石來(lái)源之間存在差異，其差異程度超出測(cè)量誤差；而最初的研究表明，對(duì)于來(lái)自單獨(dú)一個(gè)銅礦石來(lái)源的鉛來(lái)說(shuō)，其同位素構(gòu)成幾乎是毫無(wú)二致的。
難句類型：復(fù)雜修飾、插入語(yǔ)、專業(yè)抽象詞解釋：本句是一個(gè)怪異的現(xiàn)象的典型例子：句子的結(jié)構(gòu)談不上復(fù)雜，所用單詞也不難，但是除非讀者有理工科的科研（是材料科學(xué)的科研）背景，否則句子雖然能夠得讀下來(lái)，但是卻搞不清句子說(shuō)的是什么意思。首先，句子中出現(xiàn)的一些詞匯雖然也都比較常見，但是在理科文章中出現(xiàn)，就有了專有名詞的意味，同時(shí)還帶有很抽象的學(xué)術(shù)含義，筆者稱之為專業(yè)抽象詞，如isotopic composition；source；variation；measurement error；preliminary study等。認(rèn)識(shí)這些單詞，并不意味著懂得它們?cè)谖恼碌囊饬x和作用。比如說(shuō)measurement error，大家都可以望文生義地理解成測(cè)量錯(cuò)誤、測(cè)量誤差，但是在對(duì)文章的閱讀中這種字面上的理解是遠(yuǎn)遠(yuǎn)不夠的。其實(shí)此處強(qiáng)調(diào)的并不是測(cè)量中出現(xiàn)的錯(cuò)誤和毛病，而是指那些每次測(cè)量都會(huì)發(fā)生的、永遠(yuǎn)也無(wú)法避免的、在測(cè)量值和實(shí)際值之間的正常的差異。因此，本句話的真實(shí)含義也難以理解。句子只是羅列了一堆事實(shí)，而作者真正想說(shuō)的意思是什么呢？其實(shí)variations exceeding the measurement error的言外之意是這些不同variations是真正有意義的不同，而不是試驗(yàn)的誤差；那么不同礦源的銅礦的鉛同位素成分真的不同，相同的礦源的鉛同位素幾乎相同，就意味著我們可以通過(guò)測(cè)量鉛同位素的成分來(lái)確定銅礦的礦源（挖掘地）。

More probable is bird transport，either externally，by accidental attachment of the seeds to feathers，or internally，by the swallowing of fruit and subsequent excretion of the seeds. （3+） 更有可能的是鳥類運(yùn)輸：或者是通過(guò)外部途徑，即由于種籽偶然粘附在羽毛上；或者是通過(guò)內(nèi)部方式，即由于鳥類吞食果子并隨后將種籽排泄出來(lái)。
難句類型：復(fù)雜修飾、插入語(yǔ)、倒裝解釋：句首有一個(gè)倒裝，正常語(yǔ)序是bird transport is more probable.后面的句子中由于插入部分的頻繁出現(xiàn)使句子顯得十分凌亂。

68. It is not known how rare this resemblance is，or whether it is most often seen in inclusions of silicates such as garnet，whose crystallography is generally somewhat similar to that of diamond； but when present，the resemblance is regarded as compelling evidence that the diamonds and inclusions are truly cogenetic. （4） 現(xiàn)在尚不知這種類似稀少到何種地步，也不知道是否它最常見于象石榴石一類的硅酸鹽內(nèi)含物中，而這類物質(zhì)的晶體結(jié)構(gòu)普遍地在某種程度上類似于金剛石的晶體結(jié)構(gòu)。但一旦存在，這種類似就被視作極有說(shuō)服力的證據(jù)，證明金剛石與內(nèi)含物確是同源的。

Even the "radical" critiques of this mainstream research model，such as the critique developed in Divided Society，attach the issue of ethnic assimilation too mechanically to factors of economic and social mobility and are thus unable to illuminate the cultural subordination of Puerto Ricans as a colonial minority. （4+）即使是對(duì)這一主流研究模型的“激進(jìn)”批評(píng)，諸如《分裂的社會(huì)》（Divided Society）一書中所提出的那種批判，亦將少數(shù)民族同化問(wèn)題過(guò)分機(jī)構(gòu)地與經(jīng)濟(jì)和社會(huì)移動(dòng)性的因素聯(lián)系起來(lái)，因此無(wú)從闡明波多黎各人作為一個(gè)殖民地少數(shù)民族的文化從屬關(guān)系。
