摘要:

  托福閱讀考試作為很多考生必須要拿下的托福考試科目,其中有3大難題一直是考生在托福閱讀成績提升路上的阻礙,那就是詞匯、長難句和文章結構。在這里小編就要提醒大家如果想要你的托福閱讀獲得高分,甚至是托福考試成績得到提升,這3個方面的提升是必不可少的。

  對于托福閱讀的提分,今天小編從一個托福閱讀原文例子來為大家分析托福閱讀考試當中的詞匯、長難句以及文章結構,希望可以幫助到大家。

  托福閱讀例子原文:

  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, according to 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.

“托福閱讀高分你必須吃透3方面內容”

  1、難詞

  spatial:a.1.空間的,太空的;2.存在(或者發(fā)生)于宇宙空間的

  plume:n.1.羽狀物2.柱,地柱

  xenolith:俘虜巖

  percolate:v.1.滲透2.擴散到,彌漫于

  portions:n.一部分

  2、難句

  難句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,mostgeologists contend,is the upper mantle.

  對于地幔分層論點來說,最好的證據(jù)乃這樣一個確認的事實,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)的物質根本不同的物質構成的,而這一海洋中部山脊系統(tǒng)的成因,大多數(shù)地質學家論辯道,為上部地幔。

  難句類型:復雜修飾、插入語

  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之后說明fact的同位語從句。此從句中既有大段插入語,又有從句,較為難讀。同位語從句的主語是volcanic rocks,主語后面的found on oceanic islands是分詞修飾volcanic rocks的;islands后面又有一個說明islands的同位語islands believed to result from mantle plumes arising from the lower mantle,此同位語實際起到一個分隔主謂的同位語的作用。其后是謂語動詞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。如果拋開文章不說,單看這一個句子,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,這應該可以推測出,既然不同于上層地幔,則這個理論一定是在說地幔有不同的層面。

  難句2.

  some geologists,however,on the basis of observations concerning mantlexenoliths,argue that the mantle isnot layered,but that heterogeneity is created by fluids rich in "incompatible elements" (elements tending towardliquid rather than solid state) percolating upward and transforming portions of the upper mantleirregularly,according to the vagaries of the fluids’ pathways.

  但是,某些地質學家,以對地幔捕虜巖體(xenolith)所作的觀察為依據(jù),指出地幔并非是分層排列的,相反,地幔的異質性是由那些富含“不相容成分”的流質構成的,這些成分趨向于流體而非固體的狀態(tài),自下而上滲透擴散,并依照這些流質流向的任意性,不規(guī)則地將上部地幔的某些部分予以改變。

  難句類型:復雜修飾、插入語

  解釋:

  本句的主句中有一個長插入語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引導的賓語從句中,從句中有由but所連接的兩個句子,一起延續(xù)到句末。首選是rich in incompatible elements修飾fluids;后面又有一個同位語和一個分詞結構,都是修飾incompatible elements的,最后還有一個狀語來修飾那個分詞結構,層層修飾,比較復雜。

  3、文章結構

  Ts是文章的第一句,因此這一篇短文章是結論解釋型。文章開始說出了地幔是heterogeneous,然后又指出了他的spatial arrangement remains unresolved,然后提出了兩種理論,一是layyered-mantle thesis,另外一個是irregularly heterogeneous.然后分別對這兩種理論進行describe.最后作者指出,We believe,perhaps unimaginatively,that this debate can be resolved through further study,and that the underexplored midocean ridge system is the key.

  托福備考過程中,若要取得勝人一籌的高分,大家就需要在應試技巧的基礎上,從難詞、難句、文章結構等方面做分析吃透,才能真正充實英語能力,提高各方面的水準。

  以上就是小編為大家整理的托福閱讀提分的3個重要內容,大家在備考時應對題目時就要從這些方面進行攻克,這樣才能讓你的托福考試獲得好的成績。最后,小編預祝大家托福考試能取得理想的成績。
