今日短語
便士 penny 是英鎊中價值最小的貨幣單位。用一便士 a penny 就能買到的東西一般情況下不珍貴，而且價值較低。因此，表達 ten a penny “用一便士能買到十個”既說明該事物隨處可見，價格很低，又可以形容一類人或一種行業(yè)“到處都有，多得遍地都是”。
例句
Builders are ten a penny, but it can be hard to find one you trust.
Coffee shops are ten a penny on many high streets today.
TV talent shows are ten a penny these days. Every channel seems to have singing, dancing or cooking competitions on every day.
請注意
相反，如果某人為了一個事物花費了 a pretty penny “相當多的便士”，那么說明它非常貴重。
例句
Wow, look at that car. That must have cost a pretty penny!
Rare toys in their original boxes, unopened, can be worth a pretty penny.
