·1. bottomless pit·
bottom 名词，“底部”，bottomless /ˈbɒtəmləs/ /ˈbɑːtəmləs/ 形容词，表示very deep; seeming to have no bottom or limit，非常深，好像没有底的，无限的。
pit /pɪt/ 名词，表示a large deep hole in the ground，地上又大又深的坑。
bottomless pit是个习语，表示a thing or situation which seems to have no limits or seems never to end，无穷无尽的东西，可以是永远填不满，等于“无底洞”，也可以是永远用不完，取之不尽，用之不竭。
往无底洞里花钱可以说：pour/throw money into a bottomless pit，或者the money goes into a bottomless pit。
例：填不满
We'll be pouring money into a bottomless pit if we try to keep that factory open.
再继续把工厂开下去，就是在往无底洞里砸钱了。
All the money just goes into a bottomless pit. No matter how much we spend, it's never enough to make a difference.
钱都花到无底洞里去了，无论我们投入多少，都没有起色。make a difference表示to have an important effect or influence，产生影响和作用。
His debts are a bottomless pit. There's no end in sight.
他的债务是个无底洞，没完没了看不到头。
例：用不完
Our budget is limited. We don't have a bottomless pit of money.
我们的预算有限，没有花不完的钱。
The Internet is a bottomless pit of information.
网上有无穷无尽的信息。
·2. money pit·
习语，用于非正式语境，表示something on which you keep having to spend a lot of money, especially when it may be a waste of money，这个短语比bottomless pit具体，形容需要人持续花钱去维护和保养的东西，比如说买了个老房子之后一直花钱在处理各种问题，或者一辆车总是出故障要花钱修。
例：The thing about used cars is, even if they're cheap at first, they can turn into money pits once they start breaking down.
二手车的问题在于，哪怕一开始很便宜，只要开始出故障，要维修就要没完没了地花钱。used /juːzd/ 形容词，等于second-hand，二手的，别人用过的。
例：We thought the café would be a great investment, but with the rent and repairs, it's just a total money pit now.
我们本来以为这个咖啡馆很值得投资，结果现在一直在花钱交租和维护，跟个无底洞一样。
·3. throw good money after bad·
习语，表示to waste money by spending more money on something you have already spent money on that is no good，在某个东西上花了钱，结果并不好，不甘心之前花的钱就这么打水漂了，所以继续往里边投钱，试图挽回损失（但大概率不能挽回），有些语境里这个习语会翻译成“在填无底洞，在花冤枉钱”。
例：Trying to fix that old car would just be throwing good money after bad.
继续花钱修这台老车就是在花冤枉钱。
例：Putting more money into that café is just throwing good money after bad. You should just close it down.
继续投资这家咖啡厅只会越亏越多，直接关掉吧。close down表示关门、永久停业，也可以说shut down。
·4. 及时止损：cut your losses·
习语，表示to stop doing something that is failing, so that you do not waste any more money, time, or effort，浪费时间精力金钱之后及时止损，不再继续做没有收益的事。
例：Sometimes, it's better to cut your losses than keep fighting a losing battle.
有时候，及时止损比做一些无谓的挣扎好。fight a losing battle字面意思是打一场要输掉的仗，表示to try hard to do something when there is no chance that you will succeed，做一件不可能成功的事，没有希望，注定徒劳。
例：After two years of trying to save the café, we decided to cut our losses and shut it down.
这家咖啡店我们坚持开了两年，最后决定及时止损，把店关掉了。
