剖析英语六级阅读真题长难句(6)

　　下面剖析英语六级阅读真题长难句，希望考生在练习同时思考长难句的句子结构。

　　1. The notion that learning should have in it an element of inspired play would seem to the greater part of the academic establishment merely silly, but that is nonetheless the case.

　　【译文】学习中应该包括具有启发性的娱乐这一观点对于大部分学术机构而言似乎是愚蠢的，但事实的确如此。

　　【析句】本例句的难点在于寻找主句的主干。很明显，主句由but连接两个并列句组成，but后的句子that is nonetheless the case是简单句。but前的句子主句是the notion would seem merely silly to the greater part of the academic establishment，to在这里作介词，这一介宾结构提前放在了谓语动词seem后，容易让人误以为是短语seem to的用法，结果导致理解失误。最后主句主语the notion有that引导的定语从句修饰。

　　2. Already the public agencies for adult education are swamped by the tide that has swept over them since depression began.

　　【译文】从事成人教育的公共机构已经因为经济萧条开始以来席卷全国的趋势而陷入困境。

　　【析句】例句2的句子结构并不复杂，主句the public agencies for adult education are swamped by the tide, that has swept over them...作定语从句修饰the tide, 而定语从句中，又有since引导的时间状语从句，这个时间是修饰swept over这个动作的。

　　3. A new high-performance contact lens under development at the department for applied physics at the University of Heidelberg will not only correct ordinary vision defects but will enhance normal night vision as much as five times, making peoples vision sharper than that of cats.

　　【译文】海德堡大学应用物理系正在研究的高水平新型隐形眼镜不仅能矫正普通的视力问题，还能把正常夜间视力提高五倍，使人的视力比猫还要敏锐。

　　【析句】复合句。主句是A new high-performance contact lens will not only correct ordinary vision defects but will enhance normal night vision, 可以看出，主句的主干是not only...but结构连接前后两个并列句，contanct lens后有几个介词短语点明了研究的地点。最后，making peoples vision...是现在分词引导结果状语。
