fuel是燃料，add fuel to the fire字面上是「在火里添加燃料」，而它引申出来的意思是让原本负面的情况更加恶化，也就是中文所说的「火上加油」。
• My assignment was due yesterday and I was behind schedule. Little did I know my laptop just quit working. It really added fuel to the fire.
我的作业昨天就该交了，而我却进度落后，没想到我的笔电这时竟然坏掉了，这真是火上加油。
✏️ have too many irons in the fire 同时要做很多事情
当某人“have too many irons in the fire” 就表示他同时要处理很多事情，有点兼顾不来的意思。

✏️ burn a hole in one’s pocket 某人花钱如流水
这句成语字面上的意思是「在某人的口袋烧一个洞」，大家可以想像，口袋如果破洞的话，钱就会掉出来，因此引申为「某人花钱如流水」的意思。
• Don’t let the bonus you just earned burn a hole in your pocket. You never know when you’ll need it.
别乱花你才刚赚到的奖金，你永远不会知道何时会需要这笔钱。
