下面是2014年6月英語六級閱讀真題長難句解析(10)，請考生仔細分析句子結構。
　　1. Conflict, defined as opposition among social entities directed against one another is distinguished from competition, defined as opposition among social entities independently striving for something which is in inadequate supply. (1996. 閱讀. 1. Text 2)
　　【譯文】沖突的定義是社會實體與另一實體間的對抗，而競爭的定義是不同社會實體間獨立爭奪供應不足的資源而發生的對抗。這兩者的性質是截然不同。
　　【析句】主句是Conflict is distinguished from competition,主語conflict后，defined as oppostion among social entities directed against one another為過去分詞作定語，相當于which is defined as...。同樣，介詞賓語competition后也有相同的結構，使得句子前后對稱。而后一句中，social entities后又有striving for some thing現在分詞作定語修飾social entities,而something后是which引導的定語從句。
　　2. While it is true that this competition may induce efforts to expand territory at the expense of others, and thus lead to conflict, it cannot be said that war-like conflict among nations is inevitable, although competition is. (1996. 閱讀. 1. Text 2)
　　【譯文】這種競爭可能真得會導致國家竭力侵占他國以擴大本國領土，沖突隨之產生，但是即使國家之間的競爭是不可避免的，也不能說發生類似戰爭的沖突同樣無法避免。
　　【析句】復合句。首先是while作連詞引導的與主句含義相反的句子，while it is true that this competition may induce efforts to expand...and thus lead to conflict,it is true that從句中，it作形式主語，真正的主語是后面的that引導的主語從句。主句在句中，同樣是it作形式主語，真正的主語是后面的that從句，而that從句中，主句是war-like conflict is inevitable，后面是although引導的讓步狀語從句。
　　3. Having evolved when the pace of life was slower, the human brain has an inherent defect that prevents it from absorbing several streams of information simultaneously and acting on them quickly. (1996. 閱讀. 1. Text3)
　　【譯文】人腦在生活節奏更慢的過去得到進化，因此人腦內部存在著缺陷，使它不能同時理解多條信息流并迅速采取行動。
　　【析句】復合句。主句是the human brain has an inherent defect,defect后是定語從句that prevents it from absorbing...and acting...。主句前，having evolved...是現在分詞作原因狀語，同時句子中又包含了時間主語從句when the pace of life was slower表明having evolved的時間。
