without which

在Cambridge文法書讀到"uint93 關係子句補述用法"時, 
看到了這個句子:
Fortunately we had a map, without which we would have gotten lost. -----------s1

雖然類似的句子s5改成s6,我就是念得很順
"I forgot my passport, without which I cannot board the plane."-----------s5

"I forgot my passport, which I cannot board the plane without." ----------s6

但s1改成s2我就是怎麼念怎麼怪
"Fortunately we had a map, which we would have gotten lost without ." -------s2


首先第一件我要確定的事是
 "without"的用法是否可以如s3這樣用?

 "we would have gotten lost without a map"----------------------s3
結果在網路上找到類似的句子s4
 I'm sure we would have gotten lost without this helpful sign-------------s4

所以因該可以再繼續找其他可以佐證的範例
很幸運的,有人問了幾乎跟我99%一樣的問題
s7是否能寫成s8

Fortunately we got a map, without which we would have gotten lost.----------s7


Fortunately we got a map, which we would have gotten lost without.---------s8

答案是可以,但大家似乎比較喜歡用s7的寫法,所以我這邊的結論就是s1可以寫成s2,但建議寫s1!!!
