If anything bad happens to you,

如果你发生了任何不幸的事，

you will remember the cause and avoid it the next time you come across the same situation

就会记住原因并在下一次遇到相同的情况时避开它。

For example,if you have been bitten by a snake,

比如说，你曾经被一条蛇咬过，

you'll surely¹ shy away from it the next time you see it.

那么当你下次再看到它时，就一定会远离它。

So goes an old saying, "Once bitten twice shy. "

有句老话说：“一朝被蛇咬，十年怕草绳。”
