同学你好~
原话是没有的，但是相关知识在课件第17页有讲解。
The village might have never been discovered had it not been for the Battle of Waterloo.

当虚拟条件句的谓语部分含有were, should, had时，我们可以将连词if省略掉，而将were, should, had置于句首。如：

If she were in charge, she would do things differently.
=Were she in charge, she would do things differently. 如果是她负责，她会是另一种做法。

If you should change your mind, no one would blame you.
=Should you change your mind, no one would blame you. 万一你改变主意，谁也不会怨你。

If the management had acted sooner, the strike wouldn’t have happened.
= Had the management acted sooner, the strike wouldn’t have happened. 如果资方早些采取行动，就不会发生罢工了。

had it not been for the Battle of Waterloo 是if it had not been for the Battle of Waterloo变化而来的

had it not been for 也是一个比较常用的短语，意思是“若非，要不是”

She might have forgotten her completely had it not been for recurrent nightmares.
要不是因为反复做噩梦，她可能已经把她彻底忘了。

祝同学学习进步~
