invaluable,valueless
这一对形容词都是来自名词value.一个是在形容词valuable(有价值的)之前加上否定形容词前缀in-;另一个是在名词value(价值)的后面加上否定形容词后缀-less.虽然它们都是加上否定的形容词词缀,意义刚好相反。
Invaluable的意思是非常贵重的,(highly valuable,precious),其同义词是priceless.例:
Your services are invaluable to us.
你对我们的帮助是极其宝贵的。
This jade bracelet is really an invaluable to article.
这件玉镯确实是非常贵重的物品。
Valueless的意思是毫无价值的,其同义词是worthless.例:
That book is valueless.
那本书毫无价值可言。
现将这两个字用在一个句中,以便区别:
The book that he considered valueless proved invaluable to us.
他认为毫无价值的那本书对我们说来却是无价之宝。
请注意,costly和invaluable的内涵并不一样,前者是某物因精美或珍奇而昂贵,后者则指价值大得无法以金钱衡量。
