(go) down the drain

前功尽弃；白费心机；付诸流水


All our efforts went down the drain when the power went out.
电一停，我们努力全付诸流水。

(go) down the drain

前功尽弃；白费心机；付诸流水

go down the drain 前功尽弃；白费心机；
All our efforts went down the drain when the power went out .
电一停，我们的努力就全白费了。

All our efforts went down the drain when the power went out

All our efforts went down the drain because of your rudeness. [s:23]

my efforts go down the drain
