The immediate causes,” Mao explained, “are the severe new demands of Japan, capitulation to which must enormously handicap any attempts at resistance in the future, and the popular response to this deepening threat of Japanese invasion in the form of a great people’s patriotic movement.



請(qǐng)教專家老師們，這里先行詞which是做介詞to的賓語嗎？介詞短語to which 是不是做定語從句主語capitulation的定語？若是的話只見過of which有這種使用方法，to which也能這么用嗎？

定語從句中，關(guān)系代詞做介詞賓語，介詞短語作定語修飾定語從句的主語，這種結(jié)構(gòu)最容易見到的介詞為of, 但絕不限于of。理論上任何介詞都可以這么用，只須符合邏輯即可。比如：

... electrically-powered cars，the demand for which has increased.

...the students, the design by whom has been approved.

...the woman, the sepation from whom saddened him.

等等。
