worth， worthy， worthwhile 这三个词均可表示“值得的”，由于它们词形相近，意义相似，所以许多同学经常将其用混。它们的用法区别：
一、从句法功能上看
从句法功能上看:
worth 通常只用作表语，不用于名词前作定语;
worthy 和 worthwhile 可用作表语和定语。如：
This second-hand car is worth $2000 at the most.
The exhibition is worth a visit/visiting.
It isn‘t worth the trouble. 不值得费那个事。
This phenomenon is worthy of being studied.这种现象值得研究。
That is worthy of note.那件事值得注意。
He is a worthy gentleman. 他是位值得尊敬的绅士。
His behavior is worthy of great praise. 他的行为值得高度赞扬。
They achieved a very worthwhile result. 他们取得了很有价值的成果。
We had a long wait， but it was worthwhile because we got the tickets. 我们等了很久，但还算值得，因为我们把票买到了。
二、从所使用的修饰语来看
worth 习惯上不用 very 修饰，而 worthy 和 worthwhile 则可以用副词very修饰。如：
That is very worthy of our attention. 那件事很值得我们注意。
Nursing is a very worthwhile career. 护理工作是很值得干的职业。
但习惯上不说：The work is very worth doing. 。
三、从搭配习惯来看
有关 be worth 的搭配习惯be worth后可直接跟名词、代词或动名词。如：
The picture is worth $ 500. 这幅画值500 美元。
The clock is hardly worth repairing. 这台钟简直不值得修理。
What is worth doing is worth doing well. 值得干的事就得干好。
注意：其后可接动名词，不能接不定式，且接动名词时，总是用主动形式表示被动意义。
在现代英语中，在be worth前使用形式主语it被认为是合习惯的。如：
It isn‘t worth repairing the car. 这辆汽车不值得修了。
Is it worth visiting the city? 这个城市值得去看吗?
但是，若不用形式主语it而直接用动名词作主语则是错误的，如：误：Repairing the car is worth.
在be worth doing 结构中，除非句首用了形式主语it，否则句子主语总应是其动名词的逻辑宾语;若其中的动词不及物，应考虑加上适当的介词。如：Nothing he said was worth listening to. 他说的话没有一句值得听。
She’s not worth getting angry with. 犯不上跟她生气。
2. 有关 be worthy 的搭配习惯
be worthy 后不能直接跟名词、代词或动名词，若要接，应借助介词 of.如：Their efforts are worthy of your support. 他们的努力应得到你的支持。 Her behavior is worthy of praise. 她的行为是值得赞扬的。
与be worth后只接动名词不接不定式不同，be worthy后不接动名词，而接不定式。如：
He is worthy to receive such honor. 他应该得到这种荣誉。
This suggestion is worthy to be considered. 这个建议值得考虑。
若要在be worthy后接动名词，与后接名词时的情形一样，应借助介词of，且该动名词若要表示被动意义，要用被动形式。如：
He is worthy of filling the post. 这个职位他当之无愧。
This suggestion is worthy of being considered [= This suggestion is worthy to be considered]. 这个建议值得考虑。
3. 有关 be worthwhile 的搭配习惯的搭配习惯
be worthwhile 后接动名词或不定式均可。如：
It is worthwhile buying the dictionary. 这本词典值得买。
It is worthwhile to discuss the plan again. 这个计划值得再讨论一次。
有时可将worthwhile分开写，此时也可在其中加上one‘s.如：I’d think it worth while to go. 我认为值得去。
The President"s trip to Washington this week seems to have been worthwhile
总统本周的华盛顿之行看来是有价值的。
It is worth while paying a vistlt to the great wall.
