  同學(xué)們?nèi)绾螒?yīng)對備考gre 閱讀難句呢?下面是澳際小編為同學(xué)們搜索整理了GRE閱讀考試難句訓(xùn)練(1)介紹。希望對同學(xué)們的gre 考試有所幫助,下面和澳際小編一起來看看吧:

  1. It is one of nature’s great ironies that the availability of nitrogen in the soil frequently sets an upper limit on plant growth even though the plants’ leaves are bathed in a sea of nitrogen gas.(3+)下述情形真可謂是自然界的一個莫大諷刺:土壤中所能獲得的氮肥量往往對植物的生長構(gòu)成了一個上限,雖然植物的葉子被沐浴在一片氮氣的海洋中。

  難句類型:復(fù)雜修飾

  解釋:It是形式主語,其真正的內(nèi)容是that之后的由even though連接的兩個句子。其實本句的真正難度倒不在于句子的結(jié)構(gòu),而是對于其意思的理解:尤其是文科同學(xué),可能缺乏必要的背景知識,就更不容易讀懂。句中的set an upper limit on plant growth直譯為”給植物的生成設(shè)立一個上限”,其真正的意思是“限制了植物的生長”;因此the availability of nitrogen in the soil frequently sets an upper limit on plant growth之中的availability一定指的是氮的供給之少。整句話的意思是,土壤中的氮植物能夠利用,卻太少;而空氣中雖有大量的氮,植物卻不能利用,這豈不是自然界開的一個大玩笑。

  It is one of nature’s great ironies that the availability of nitrogen in the soil frequently sets an upper limit on plant growth even though the plants’ leaves are bathed in a sea of nitrogen gas.

  2. Unless they succeed,the yield gains of the Green Revolution will be largely lost even if the genes in legumes that equip those plants to enter into a symbiosis with nitrogen fixers are identified and isolated,and even if the transfer of those gene complexes,once they are found, becomes possible. (4)

  除非他們能取得成功,不然的話,綠色革命的產(chǎn)量收益將在很大程度上損失殆盡,即使豆科植物中使這些植物有條件進(jìn)入到與固氮細(xì)菌共生關(guān)系的基因可被辨識出來和分離開來的話,且即使這些基因綜合體(gene complex),一旦被發(fā)現(xiàn)之后,其移植得以成為可能的話。

  難句類型:復(fù)雜修飾、插入語

  解釋:主句比較簡單,而后面跟著的由and連接的兩個表示讓步的條件狀語從句就相對復(fù)雜,第一個從句是用一個修飾主語的定語從句that equip those plants to enter into a symbiosis with nitrogen fixers把主謂隔開;第二個從句則運用了插入語once they are found把主謂隔開。

  意群訓(xùn)練:Unless they succeed,the yield gains of the Green Revolution will be largely lost even if the genes in legumes that equip those plants to enter into a symbiosis with nitrogen fixers are identified and isolated,and even if the transfer of those gene complexes,once they are found, becomes possible.

  3.One such novel idea is that (idea) of inserting into the chromosomes of plants discrete genes that are not a part of the plants’ natural constitution:specifically,the idea of inserting into  nonleguminous plants the genes,if they can be identified and isolated,that fit the leguminous plants to be hosts for nitrogen-fixing bacteria. Hence,(there is ) the intensified research on legumes. (5),此句最好能夠熟讀,更好的是背誦下來。(復(fù)雜修飾+插入+省略+倒裝)

  這其中的一個新穎思想就是,在植物的染色體(chromosome)內(nèi)注入并非是該植物自然構(gòu)造一個部分的那些不相關(guān)聯(lián)的因基:具體而言,這一思想是,在非豆科植物內(nèi)注入這樣一些基因,倘若這些基因可被辨識出來并被分離開來,而這些基因業(yè)已使豆科植物宜于充當(dāng)那些具備固氮作用的細(xì)菌的寄主。由此,對豆科植物的研究日趨深入。

  難句類型:復(fù)雜修飾、插入語、倒裝、省略

  解釋:本句的難度以倒裝為主,復(fù)雜為輔;然而二者相互借力,難度更大,而且本句中有兩個省略,就更令讀者頭痛。

  句子一開始的One such novel idea is that of 之中的that of, 是that idea of 的省略形式。此外容易理解,后面開始變難。Inserting into the chromosomes of plants discrete genes(that are not a part of the plants&apos natureal consttution)看上去不舒服的原因,是作者在此用了一個便裝;正常語序應(yīng)該是:inserting discrete genes(that are not a part of the plants&apos natureal constitution) into the chromosomes of plants, 即把非此植物的genes插入到該植物中。之所以倒裝,是因為discrete genes加上復(fù)雜修飾的成分以后太長之故。同樣,后面的the idea of inserting into nonleguminous plants the genes, if they can be identifyied and isolated, that fit the leguminous plants to be hosts for nitrogen-fixing bacteria一句,正常的語序也是the idea of inserting the genes, if they can be identifyied and isolated, that fit the leguminous plants to be hosts for nitro-fixing bacteria into nonleguminous plants,即把便利豆科植物成為固氮菌的寄主的基因(如果它們能夠被找到并分離出來的話)插入到非豆科植物的基因中去。這一回。Genes之后不但有定語從句的復(fù)雜修飾,而且在genes和that從句之間還有一個不短的插入語,增加了閱讀難度。

  最后的一句話,Hence, the intensified research on legumes, 其實也不是一句話,只是一個詞:research。作者省略了there is ,其實引處即便看不清語法結(jié)構(gòu),作者的意思還是可以懂的。因此,筆者在前面強(qiáng)調(diào)的“如果可以看懂意思,不必去分析語法”,在實戰(zhàn)的應(yīng)用中有其意義;GRE和GMAT中很多表達(dá)其實不嚴(yán)格遵守語法,或者有考生不懂的語法,讀者處心積慮地研究它們,不但沒有實戰(zhàn)意義,而且還令讀者徒增煩惱。

  本句是GRE和GMAT考試中集各種語言現(xiàn)象之大成者,包括了幾乎所有的難句類型,希望讀者一定把這句話讀熟;有心者最好能把它背熟,一定對提高你的閱讀能力有好處。

Hence,(there is ) the intensified research on legumes.
