雅思阅读长难句100句及翻译(3)

　　46. It is one of natures 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. 下述情形真可谓是自然界的一个莫大讽刺：土壤中所能获得的氮肥量往往对植物的生长构成了一个上限，虽然植物的叶子被沐浴在一片氮气的海洋中。

　　47. 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. 除非他们能取得成功，不然的话，绿色革命的产量收益将在很大程度上损失殆尽，即使豆科植物中使这些植物有条件进入到与固氮细菌共生关系的基因可被辨识出来和分离开来的话，且即使这些基因综合体（gene complex），一旦被发现之后，其移植得以成为可能的话。

　　48. Its subjectis 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. 其主题〔若借鉴梅纳德。迈克（Maynard Mack）的两个分类范畴的话〕是人生作为外部景象，因为读者的注意力被作品那形形色色的事件所分散，主要是从外部来观察其主人公奥德修斯（Odyssus）的；然而，富于悲剧色彩的《伊利亚特》所表现的则是人生作为内心体验：读者被要求与阿基琉斯（Achilles）的心灵产生共鸣，而其行为动机却致使他变作一个并非特别惹人喜爱的主人公。（从分号后的语句推理出前面的意思）注：hero:主人公；without:外部；likable:有吸引力的
