“一舉兩得”，漢語成語，意思是做一件事，能同時得到兩方面的好處。與英文習(xí)語“ kill two birds with one stone”意思相似，表示“achieve two ends with a single effort；to solve two problems with one action or solution”。

例句：

騎自行車上班既可以鍛煉身體，又能減少每天上下班的費用，是一舉兩得的好辦法。
Bike-to-work schemes are a great way of killing two birds with one stone: getting more exercise while cutting down on the cost of your daily commute.

我們可以在去雜貨店時把郵件寄出去，這樣就能一舉兩得。
We can kill two birds with one stone by dropping off the mail when we go to the grocery store.
