讀GRE閱讀重要培養(yǎng)GRE閱讀能力.

　　對(duì)GRE閱讀理解是必須使用結(jié)構(gòu)化的巡讀法進(jìn)行，這樣效率高、收效高，因?yàn)镚RE以閱讀理解的規(guī)律性非常強(qiáng)，同時(shí)我們閱讀是閱讀其文章的邏輯，因此是用邏輯思維操作邏輯閱讀。GRE閱讀重點(diǎn)就是培養(yǎng)GRE閱讀能力，如何做到下面為大家分析。

　　我們也要知道能做對(duì)GRE閱讀題目的同時(shí)，我們也要通過(guò)每一篇GRE、GMAT閱讀文章來(lái)強(qiáng)化訓(xùn)練自己實(shí)實(shí)在在的閱讀能力。例如：長(zhǎng)難句的分析能力、詞匯的積累，寫作素材的積累、以及寫作結(jié)構(gòu)的掌握?？梢哉f(shuō)，每一篇GRE閱讀理解都是我們備考 GRE、GMAT寫作的Issue部分的最好的素材庫(kù)以及范文展示。

　　現(xiàn)在，我們拿GRE閱讀NO題的NO8-1這篇文章做一個(gè)示范，來(lái)說(shuō)明一下怎樣提高新GRE閱讀能力。

　　NO8-1，我們從“詞--句--篇章”來(lái)談?wù)勥@篇文章。

　　原文：

　　Geologists have long known that the Earth‘s mantle is heterogeneous， but its spatial arrangement remains unresolved—is the mantle essentially layered or irregularly heterogeneous? 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 midocean ridge system， whose source， most geologists contend， is the upper mantle.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， accordingto the vagaries of the fluids’ pathways. We believe， perhaps unimaginatively， that this debate can be resolved through further study， and that the underexplored midocean ridge system is the key.

　　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。
