Cash Cow
In business, a cash cow is a product or investment that steadily continues to be profitable.
Example
The retail division is BT's cash cow.
零售部是英國電信公司的搖錢樹。
The new movie theater that they just opened by campus is a real cash cow.
學校旁邊新開的電影院真是個搖錢樹啊。
Also, environmental groups caution that, designed poorly, programs to pay for forest preservation could merely serve as a cash cow for the very people who are destroying them.
環保組織還警告說,如果設計的不好,支付森林保護的計劃可能只會成為正在摧毀森林的某些人的搖錢樹。
Whatever happens tomorrow, we had today.
不管明天會發生什麼,我們還有今天。
