复杂的状语从句的拆分和理解 例135

例135　Indeed, only if we take note of what enabled man to survive against every conceivable hardship and danger, and what allowed him to adjust to the most drastic changes in his environment which finished many species less adaptable than himself, we will see that it was his instinct for cooperation.

【结构分析】这句话条件句是only if we take note of...，里面套上两个并列宾语从句，第一个宾语从句是what enabled man to survive against every conceivable hardship and danger，第二个宾语从句是what allowed him to adjust to the most drastic changes in his environment...，后面套上定语从句which finished many species...，后面套上比较级短语less adaptable than himself做定语，主干是we will see that it was his instinct for cooperation。

【亮点回放】此句话的亮点在于条件句的成功使用，其中套有两个超级的并列宾语从句，其中第二个宾语从句套有定语从句和比较级短语，很经典，两个宾语从句层层递进，确实很有气势。
