[問題]朗文拖福聖經完全自修版-結構-P253 技巧20-23 第四題

[vinsem]

請問
第四題這題的文法
She would not have to enter the house through the bedroom windows were the keys where they were supposed to be.

解答說這題的文法正確，但我有個疑問，為何這題的動詞有兩個呢？
She would not have to enter the house through the bedroom windows were
the keys where they were supposed to be.

我把句子分成兩段，只是，句子可以當作主詞嗎？？？？:|||
She would not have to enter the house through the bedroom windows

were

the keys where they were supposed to be.

另外，我翻不出中文的意思
我自己翻成：她不需從窗戶進入屋子是他們假設的關鍵。
可是感覺很怪，拜託大家幫我解答一下，謝謝！

我覺得原句是這樣:
She would not have to enter the house through the bedroom windows if the keys were where they were supposed to be.
然後省略 if 將 were 提前

一語驚醒夢中人

原來是省略if...
我還以為只有句首可以省略，謝謝維尼 真是太厲害了！
