点睛

这两句中两个相似的表达run out of和be out of，都表示“用完了；没有……了”。

考点归纳

应当注意的是，有些与out有关的表达与be out of形似，含义却大不一样。如：
Out of sight, out of mind. 眼不见，心不烦。
We've got to be out of our minds. 我们一定昏了头。
David has been out of collar since last autumn. 戴维从去年秋天起就失业了。
Don't trust him—he's only out for your money. 别相信他——他只是图你的钱。
