這三個(gè)詞都是形容詞,都有“值得的”的意思,但用法或搭配關(guān)系不同.
1.worth是一個(gè)只能作表語(yǔ)的形容詞,意思為“值……的”、“相當(dāng)于……的價(jià)值的”、“有……價(jià)值的”、“值得……的”.由于它類(lèi)似介詞,須在后面接名詞、或主動(dòng)形式的動(dòng)名詞作賓語(yǔ).例如：
This second-hand car is worth $2000 at the most.
The exhibition is worth a visit/visiting.
It’s not worth getting angry with him.
2.worthy可作表語(yǔ),也可作定語(yǔ).作定語(yǔ)時(shí)意思為“有價(jià)值的”、“值得尊敬的”、“應(yīng)受到賞識(shí)的”；用作表語(yǔ)時(shí)意思為“值得……的”、“應(yīng)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.
He said he was not worthy to accept such honour
The school has educated many worthy young people.
3.worthwhile與worthy一樣,既可作表語(yǔ),又可作定語(yǔ).表示某事因重要、有趣或受益大而值得花時(shí)間、金錢(qián)或努力去做,一般做“值得的”、“值得做的”、“有意義的”解.用作表語(yǔ)時(shí),可接動(dòng)名詞或動(dòng)詞不定式.例如：
The Summer Palace is worthwhile going / to go to have a visit.
Helping old people is a worthwhile activity.
Thank you for your worthwhile suggestion.
