    要是在父亲面前抱怨母亲做的饭,那可不得了。
  • この辺あたりは、少すこしでも雨あめが降ふろうものなら、すぐに道どう路ろが冠かん水すいしてしまう。
    Around here, if it rains even a little, the roads flood right away.
    这一带只要稍微下点雨,道路就会立刻积水。
  • 締しめ切きりに一いち日にちでも遅おくれようものなら、二に度どと仕し事ごとをもらえなくなるだろう。
    If you were even one day late for the deadline, you'd never get work from them again.

Notes

Exaggerates the danger of an action. Not to be confused with 〜ものなら (N2), which takes the potential form for an unlikely wish: 行けるものなら行きたい.
