Usage Note :
Be careful not to confuse the words worthless, invaluable and priceless. Something which is priceless is so precious that it is difficult to give it a value. ...priceless masterpieces by Canova and Bernini. Something which is invaluable is very useful indeed. It has a spelling checker, which is invaluable if you are dyslexic. In contrast, something that is worthless is of very little value. I'm afraid your shares are now worthless.
注意不要混淆 worthless, invaluable和 priceless。priceless 指非常宝贵，价值难以估量：priceless masterpieces by Canova and Bernini (卡诺瓦与贝尔尼尼的无价杰作)。invaluable指非常有用：It has a spelling checker, which is very invaluable if you are dyslexic (它有一个拼写检查程序，对有诵读困难的人非常有用)。而worthless则意为几乎毫无价值：I'm afraid your shares are now worthless (恐怕你的股票现在一文不值了)。
