worthwhile 强调答案本身值得并且有意义的
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”.后接名词、接动名词的主动形式.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.
The question is not worth discussing again and again.
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：
①That is worthy of note.那件事值得注意.
②This phenomenon is worthy of being studied.这种现象值得研究.
③This problem is worthy to be considered.这个问题值得考虑.
④The film is worthy to be seen again.这部电影值得再看一遍.
⑤This is a worthy English-Chinese dictionary.这是一本有价值的英汉词典.
⑥This is a worthy article.这是一篇值得一看的文章.
⑦He said he was not worthy to accept such honour
⑧The school has educated many worthy young people.
⑨The question is not worthy to be discussed again and again.
作后置定语时,必须用“worthy of +名词”结构.例如：
⑩There is nothing worthy of mention.没有值得一提的事情.
②This is behavior worthy of praise.这是值得称赞的行为.
③ Something find and rare --- something worthy of the honor of being owned by Jim.
(S3 Unit 10 P84)
注：“worthy of+动名词”与“worth+动名词”在形式上完全不同：worthy of后面接被动式的动名词；而worth后面接主动式的动名词,虽然在形式上是主动的,但其意义仍然是被动的.试比较：
The second-hand house is worthy of being bought.= The second-hand house is worth buying.
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：
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.
I really feel I am doing something worthwhile and I am having a great time doing it.
