The theif hadn't been knee on_________〔steal〕copies.填正确的动词形式。

If it hadn’t been for the determined captain, all the passengers on board wouldn’t have been saved~

不是的 been 其实是个be动词 be动词后面不是一定要加动词的~ 比如说，这本书是给你的 就是 this book is for you be 动词后面可以接名词，介词，动词，形容词，等等~

1.If虚拟条件句的否定（含蓄条件句） 常考两个句型：If it weren’t for…和If it hadn’t been for…，其意为“若不是(有)” “要不是”。
我们可以用介词短语代表条件从句，常见的介词短语有with, without, but for。
所以第一句为but for the rain。
2.if 省略句
在条件句中可省略if, 把were, had, should提到句首 , 变为倒装句式。
则第二句为 Had you come earlier。

答案：stealing be keen on 热衷于某事 on是介词后加sth 或者是doing
