| 释义 | oxygen (once / 656 pages) n Oxygen is air, the stuff we breathe, the thing that makes our lives possible. It is an element, a basic chemical found on the earth. In fact, we don't breathe pure oxygen; our air is about 20 percent oxygen. Still, oxygen is everywhere—it’s the third most common element on earth. Usually, the word is used in scientific contexts. Still, when someone has a big personality and likes to be the center of attention, we say, they "take all the oxygen out of the room." That means they are a blowhard and attention hog. If they really took your oxygen, you’d be dead.
