新GRE閱讀長(zhǎng)難句解析資料總結(jié)。GRE考試中閱讀部分會(huì)有一些較長(zhǎng)的有比較難以理解的句子出現(xiàn)，就是所謂的GRE閱讀理解長(zhǎng)難句，那么怎樣才能很好的攻克新GRE閱讀中的長(zhǎng)難句呢?下面小編給您整理了一些GRE考試閱讀理解難句的解題技巧，供廣大考生參考。
　　報(bào)名參加GRE考試的考生一定要注意掌握核心句子的理解，　GRE考試中新GRE閱讀理解舉例介紹：
　　1. The best evidence for the layered-mantle thesis is the well-established fact that volcanic rocks found on oceanic islands，islands believed to result from mantle plumes arising from the lower mantle，are composed of material fundamentally different from that of the mid-ocean ridge system， whose source，most　geologists contend，is the upper mantle. (5 -)
　　對(duì)于地幔分層論點(diǎn)來(lái)說(shuō)，最好的證據(jù)乃這樣一個(gè)確認(rèn)的事實(shí)，即在那些海洋島嶼——這些島嶼據(jù)信是源于由下層地幔升上來(lái)的地幔柱狀溶巖流(mantle plume)——上發(fā)現(xiàn)的火山巖石，是由與海洋中部山脊系統(tǒng)的物質(zhì)根本不同的物質(zhì)構(gòu)成的，而這一海洋中部山脊系統(tǒng)的成因，大多數(shù)地質(zhì)學(xué)家論辯道，為上部地幔。
　　難句類型：復(fù)雜修飾、插入語(yǔ)
　　解釋：本句前面的主干并不算難，即the evidence is the fact that，難就難在fact之后說(shuō)明fact 的同位語(yǔ)從句。此從句中既有大段插入語(yǔ)，又有從句，較為難讀。同位語(yǔ)從句的主語(yǔ)是volcanic rocks，主語(yǔ)后面的found on oceanic islands是分詞修飾volcanic rocks的;islands后面又有一個(gè)說(shuō)明islands的同位語(yǔ)islands believed to result from mantle plumes arising from the lower mantle，此同位語(yǔ)實(shí)際起到一個(gè)分隔主謂的同位語(yǔ)的作用。其后是謂語(yǔ)動(dòng)詞are composed/of fundamentally different from that of the midocean ridge system， whose source， most geologists contend， is the upper mantle.
　　句中有一些專有詞匯。如果拋開(kāi)文章不說(shuō)，單看這一個(gè)句子，則句首的layered mantle thesis就難以理解。但是如果讀者能夠讀懂句子的大致意思，看到layered mantle thesisr最有力證據(jù)就是其材料fundamentally different from… the upper mantle，這應(yīng)該可以推測(cè)出，既然不同于上層地幔，則這個(gè)理論一定是在說(shuō)地幔有不同的層面。
　　意群訓(xùn)練：The best evidence for the layered-mantle thesis is the well-established fact that volcanic rocks found on oceanic islands，islands believed to result from mantle plumes arising from the lower mantle，are composed of material fundamentally different from that of the mid-ocean ridge system， whose source，most　geologists contend，is the upper mantle.
　　2. 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。
　　難句類型：復(fù)雜修飾、插入語(yǔ)
　　解釋：本句的主句中有一個(gè)長(zhǎng)插入語(yǔ)however，on the basis of observations concerning mantle xenoliths，割裂了主謂，但句子的主要難度還是在that引導(dǎo)的賓語(yǔ)從句中，從句中有由but 所連接的兩個(gè)句子，一起延續(xù)到句末。首選是rich in incompatible elements修飾fluids;后面又有一個(gè)同位語(yǔ)和一個(gè)分詞結(jié)構(gòu)，都是修飾incompatible elements的，最后還有一個(gè)狀語(yǔ)來(lái)修飾那個(gè)分詞結(jié)構(gòu)，層層修飾，比較復(fù)雜。
　　意群訓(xùn)練：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.
