2017考研英语长难句分析每日一句(771) Studies of both animals and humans have shown that sex hormones somehow affect the stress response, causing females under stress to produce more of the trigger chemicals than do males under the same conditions.
【分析】多重复合句…主句主子为Studies have shown that…。that引导宾语从句,其主干是sex hormone affect the stress response。现在分词结构causing females···作结果状语,为避免头重脚轻,比较结构more···than引导的状语从句用了倒装语序,正常语序:···than males under the same conditions do,其中do替代前面的 produce。
