小知识
When you discard something, you get rid of it. If your closet is overflowing with clothes you haven't worn since 1992, why not discard some of them?
When the verb discard first entered the English language in the sixteenth century, it referred to card playing and meant “to throw a card away.” Discard is still used to describe getting rid of unlucky cards, but today, you’ll also hear it used in a broader sense — we discard, or throw away, things that are undesirable or no longer useful. You might discard a worn out shoe, for example.
