例:The methods that a community devises to perpetuate itself come into being to preserve aspects of the cultural legacy that community perceives as essential.
分析:主語是The methods,謂語是come into being,that a community devises to perpetuate itself為定語從句,修飾the methods,不定式to表示目的狀語,that community perceives as essential為定語從句,修飾the cultural legacy。
例:That sex ratio will be favored which maximizes the number of descendants and hence the number of gene copies transmitted.
分析:該例句中which引導的定語從句修飾sex ratio,由于謂語句子主干較短,所以進行了后置。另外,and并列的后半句省略了主謂語that sex ratio maximizes。正常語序:That sex ratio which maximizes the number of descendants will be favored and hence the number of gene copies transmitted.
