“一举两得”，汉语成语，意思是做一件事，能同时得到两方面的好处。与英文习语“ 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：

骑自行车上班既可以锻炼身体，又能减少每天上下班的费用，是一举两得的好办法。

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.

我们可以在去杂货店时把邮件寄出去，这样就能一举两得。

We can kill two birds with one stone by dropping off the mail when we go to the grocery store.
