英语句子分析 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
疑问 causing females under stress to produce more of the trigger chemicals than do males under the same conditions 中 为什么用 to produce?此句 是 独立主格?现在分词作状语?还是普通状语从句?
如果是分词作状语 不是应该和主句 主语一致吗?这句的主语不是females under stress?和主句 Studies of both animals and humans 不一致啊

causing.不是从句,是现在分词短语作主句的“伴随状语”.这个结构可以用非限定性从句的简略形式来解释,即 which cause females.
causing 的主语是 sex hormones,即主句的宾语从句的主语,females under stress 是 causing的宾语,而 to produce more. 则是 females under stress 的宾语补足语.
这是固定搭配吧,cause sb to do sth 我想大概是的
causing females...这里是现在分词做状语,相当于which causes引导的定语从句。
至于里面的to produce是cause sb to do sth的固定用法。
