双解例句
小知识
To supply the definition of a word is to provide that definition. That's supply used as a verb. If you're talking about the noun, however, then the supply is the thing itself.
People who think the world is coming to an end generally like to keep a supply of fresh water on hand. Though, if the world did come to an end, you wouldn't need to supply water to anyone, would you? That's a case of supplying a supply. If there is a big enough demand for ping-pong balls, a person could get rich, if they controlled the supply. Having to supply all those balls could be exhausting, though.
