　　● 题目：

　　A modern hard-core sociobiologist might even go so far as to claim that this aggressive instinct evolved as an advantageous trait, having been of survival value to our ancestors in their struggle against the hardships of life on the plains and in the carves, ultimately finding its way into our genetic make-up as a remnant of our ancient animal ways.(剑5, Test 1 passage 2)

　　● 分析：

　　本句的主句为“A modern hard-core sociobiologist might even go so far as to claim that …”;其中“that this aggressive instinct evolved as an advantageous trait, having been of survival value to our ancestors in their struggle against the hardships of life on the plains and in the carves, ultimately finding its way into our genetic make-up as a remnant of our ancient animal ways.”为that引导的宾语从句，做claim的宾语;在宾语从句中“having been of survival value to our ancestors in their struggle against the hardships of life on the plains and in the carves”为现在分词短语作状语，在该宾语从句中做原因状语，“ultimately finding its way into our genetic make-up as a remnant of our ancient animal ways.”也是现在分词短语做状语，在该宾语从句中做时间状语。
