请英语高手看看这个定语从句吧
He asserted,also,that his power to follow a long and purely abstract train of thought was very limited,for which reason he felt certain that he never could have succeeded with mathematics.在for which reason 这个句子中 which在从句中充当什么成分啊 为什么后面有个reason 后面有reason which不就充当定语了吗 可是which在从句中只能充当主语和宾语啊 用定语得用whose吧 这里先行词又是哪个呢

Answer 1

for which reason只能引导非限制性定语从句,相当于限制性定语从句的关系副词why.
注意了：这里不能用whose,因为whose不能放在介词之后.引导定语从句的关系词,如果是用介词的,介词后面只能用which.
which在从句中只充当主语和宾语,充当定语的很少.这里我们可以把which reason看成一个整体,充当for的宾语.模糊一点说,我们还是可以把which看作宾语,介词的宾语.
