今天我们要学习的短语跟“手”有关。
第一个就是标题中提到的：（from）hand to mouth。
从字面上看，它的意思是“从手到嘴”。但其实，它真正的意思是“勉强维持生计”“收入只够糊口”。
（from）hand to mouth:
With just the bare minimum of money, food, or resources to survive, with little or nothing else to spare. (Usually preceded by "live.")
只有极少的金钱、食物、资源用于为生，几乎所剩无几。（常用于“live”之后）。
例句：
With another child on the way, it looks like we'll be living from hand to mouth for the foreseeable future.
随着第二个孩子的到来，在可见的将来，他们可能要过着勉强糊口的日子了。

Can you believe the boss gave me a free hand on this project?
