7. 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入到與固氮細菌共生關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.
8. Its subject(to use Maynard Mack’s categories)is "life-as-spectacle," for readers,diverted by its various incidents,observe its hero Odysseus primarily from without;the tragic Iliad,however,presents "life-as-experience":readers are asked to identify with the mind of Achilles,whose motivations render him a not particularly likable hero.

9. Most striking among the many asymmetries evident in an adult flatfish is eye placement: before maturity one eye migrates,so that in an adult flatfish both eyes are on the same side of the head. (3+)在一條成年比目魚身上顯著存在的諸多不對稱(asymmetry)特征中,最為吸人注目的是眼睛的擺位:在成年之前,一只眼睛發(fā)生移動,因此在成年比目魚身上,兩只眼睛均位于頭部的同一側面。
難句類型:倒裝、省略
解釋:本句的倒裝本質上與我們早就的一種倒裝結構是一樣的,即形容詞放在句首時,主語和謂語倒裝。本句的主干的正常語序應該是:Eye placement is most striking;倒裝后成了Most striking is eye placement。但是這種倒裝在GRE考試中出現(xiàn),又有了新的特色,被提到句首的Most striking被長長的狀語among the many asymmetries evident in an adult flatfish與后面的主語和表語分開,造成閱讀困難。

10. A critique of Handlin’s interpretation of why legal slavery did not appear until the 1660’s suggests that assumptions about the relation between slavery and racial prejudice should be reexamined , and that explanations for the different treatment of Black slaves in North and South America should be expanded .(4)
