Yeah, you know that was nobody but she said some cruel words, which cut him the quick.
要點解析:整個句子是一個賓語從句,主句是you know,賓語從句that was nobody but she said some cruel words, which cut him the quick。
賓語從句是一個表語從句,主語是that was,從句是nobody but she said some cruel words, which cut him the quick。這里的that是指代“他失落,郁悶,傷心的情況”。
表語從句中含有一個非限定性定語從句:which cut him the quick。它起到補充說明的作用。在這里補充說明“她說了這些殘酷的話語”給他帶來的后果。
