because和if 連接詞問題

請看例句↓

Moreover, he felt grateful for all she had done "because if" she hadn't showed up in his life, he couldn't have been a professor and so successful in the society.

問題:because和if不都是連接詞嗎? 為何能出現在同一個句子中呢?

Update:

請問阿玉大大

if在此是當什麼詞性呢?

    在本句之中because 和if都是從屬連接詞,分別帶出兩個副詞子句(當修飾語),提供條件.

    if she hadn't showed up in his life是副詞子句提供後面的子句he couldn't have been a professor and so successful in the society條件(向後面修飾)

    because ...he couldn't have been a professor and so successful in the society也是一個副詞子句,但供前面的主要子句he felt grateful for all she had done條件(當修飾語)

    你可以用數學的小括號和中括號來看兩個副詞子句的關係.if用一個小括號帶出一個副詞子句,這個小括號包在中括號內,由because所帶出副詞子句內.

    Moreover, he felt grateful for all she had done [because (if she hadn't showed up in his life ,) he couldn't have been a professor and so successful in the society.]

    Moreover, he felt grateful for all she had done 主要子句,由連接詞

    because 連接另外的句子, 這個句子很長,

    if she hadn't showed up in his life, he couldn't have been a professor and so successful in the society.

    它是由if 帶領副詞子句和主要子句連接而成為與過去事實相反的假設語氣

    if+主詞+had +過去分詞,主詞+would/could/ might/should have +過去分詞

    如果不是她當時出現在他的生命中,他那時就不可能成為一位教授和社會上如此的成功了

    if 是副詞子句的連接詞而已,和when, while ,since....一樣,可以接另外一個句子,這裡如果沒if, 後面的 he could't have...就不能接著寫了.if可以當連接詞和名詞,沒有其它詞性了
