bout something. worth、 worthy、 worthwhile的用法区别 这三个词都是形容词，都有“值得的”的意思，但用法或搭配关系不同。 1. worth是一个只能作表语的形容词，意思为“值 …… 的”、“相当于 …… 的价值的”、“有 …… 价值的”、“值得 …… 的”。 由于它类似介词，须在后面接名词、或主动形式的动名词作宾语。 例如： This secondhand car is worth $2020 at the most. The exhibition is worth a visit/visiting. It’s not worth getting angry with him. I went and bought about six dollars39。 worth of potato chips. You39。 ve got three years39。 worth of research money to do what you want with. I am spending a lot of money and time on this boat, but it is worth it. 2. worthy可作表语，也可作定语。 作定语时意思为“有价值的”、“值得尊敬的”、“应受到赏识的”；用作表语时意思为“值得 …… 的”、“应得到 …… 的”，其后接 of sth.，也可以后接 to do sth.，例如： Guangzhou is worthy of a visit/ to be visited/being visited. He said he was not worthy(配得上） to accept such an honor. The school has educated many worthy young people. 3. worthwhile与 worthy一样，既可作表语，又可作定语。 表示某事因重要、有趣或受益大而值得花时间、金钱或努力去做，一般做“值得的”、“值得做的”、“有意义的”解。 用作表语时，可接动名词或动词不定式。 例如： It is worthwhile going / to go to the Summer Palace. Helping old people is a worthwhile activity. Thank you for your worthwhile suggestion. 试比较： 这个问题值得讨论： The problem is worth discussing. The problem is worthy of being discussed.
