“昨日黄花”是由“明日黄花”衍生而来的,许多人认为它是一种错误的用法,应该禁止使用。其实,“昨日黄花”的出现及其与“明日黄花”的竞争,符合语言发展的规律与史实。应该让它们自由竞争,按照语言本身的发展规律来决定优胜劣汰,没有必要过多加以人为的政策限制与选择。 “Yesterday ’s yellow flower” is derived from “Tomorrow Flower”, and many people think that it is a wrong use and should not be used. In fact, the appearance of “yesterday’s yellow flower” and its competition with the “tomorrow’s yellow flower” are consistent with the law of language development and historical facts. They should be allowed to compete freely and determine the survival of the fittest in accordance with the law of development of the language itself. There is no need to impose excessive artificial policy restrictions and choices.
