下面是2014年6月英語六級閱讀真題長難句解析(7)，請考生仔細分析句子結構。
　　1. There are several steps that can be taken, of which the chief one is to demand of all the organizations that exist with the declared objectives of safeguarding the interests of animals that they should declare clearly where they stand on violence towards people. (1993. 閱讀. 6. Text 1)
　　【譯文】可以采取若干措施，其中最主要的是要求所有宣稱保護動物權益的組織明確表明他們在暴力襲擊事件中所持的立場。
　　【析句】本例句中包含多個層層相扣的從句。主句很簡單，There are several steps,steps后緊跟有定語從句that can be taken, of which相當于of several steps,引導非限制性定語從句修飾several steps。而of which the chief one is to demand of all the organizations...that...中，包含短語demand of sb that...,to demand of為不定式作表語，all the organizations作demand of的間接賓語，并且后面有that exist with the declared...animals作定語從句修飾，demand的直接賓語是that賓語從句that they should declare where they stand on...,where引導declare的賓語從句。
　　2. Thus, for those individuals who are interested in preserving both the quality and quantity of life, personal health choices should reflect those behaviors that are associated with a statistical probability of increased vitality and longevity. (1993. 閱讀. 6. Text 4)
　　【譯文】因此，對于那些有心保持生活數量和質量的人來說，個人的健康選擇應該能夠反映那些從數據上顯示可能使人提高活力、延長壽命的行為。
　　【析句】復合句。句首，for those individuals后有定語從句who are interested in preserving...life修飾those individuals,句中是主句personal health choices should reflect those behaviors,而behaviors后也有that引導的定語從句修飾。主句前后都有從句修飾，句子結構是對成的。
　　3. A research paper, assigned in a course and perhaps checked at various stages by an instructor, leads you beyond classroom, beyond the texts for classes and into a process where the joy of discovery and learning can come to you many times. (1994. 閱讀. 1. Text 3)
　　【譯文】導師在某門課程上布置研究論文，并在不同階段進行檢查，這能夠使你的學習超越課堂，超越課本，進入到一個你能多次體會學習和發現的樂趣的過程。
　　【析句】復合句。主句是A research paper leads you beyond...,beyond...and into a process。謂語動詞leads后有多個并列的介詞短語。而assigned in a course and checked at...instructor是過去分詞作定語修飾a research paper,同時也是插入語。最后，在a process后有where引導的定語從句修飾。
