because +句子,也就是要有主語、謂語because of+名詞或結(jié)構(gòu),沒有主語、謂語例句：We have to stay at home because it is raining （+句子）=====We have to stay at home because of the rain（+名詞）...because of the heavy rain becase—it rained—heavilybecause of what he had saidwhat he had said是一個名詞性結(jié)構(gòu)，不是句子， =the words that he had said（他說所的話）He knew （that）she was crying because of what he had said 這是一個復合句子，也就是兩個句子；一個主句，一個從句 既然是兩個句子，當然有兩個主語兩個謂語了 主句： 主語：he，謂語knew，賓語：即賓語從句 從句： 主語：she ，謂語：was crying，狀語：because of what he had said what he had said 和cried 不是動賓關系，是動詞和副詞構(gòu)成的謂語+狀語的關系
