在什么事情上下赌注在英语里就是 gamble on something, 虽然很冒险，但下注者希望风险能带来收益。

例句

Don't gamble on the weather being good for your party. I know you want a barbeque, but it could rain. I'd book a venue with a covered area.

I took a gamble on employing John, but it's turned out that he's great for our team.

请注意

英语里的 to gamble something away 意思是全部赌光了，输得一干二净。Away 表示全部丢失了。

Tina gambled all of her money away by playing the lottery.
