worth、worthy、worthwhile的用法区别

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 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.He said he was not worthy to accept such honorThe 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：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.练习：用worth、worthy、worthwhile填空It’s not _______ my time.This is a _____ book.This book is ____ reading.This book is _____ of being read.This book is ________to be read.This good film is _______ seeing twice.I will do some _______ reading during the summer vacation.She is not __________ to talk to a man like you.It is ________ improving the rate of production.Their achievements are __________ of the highest praise.He is __________ to have a place in the team.We had a long wait, but it was _________ because we got the tickets. worth, worthy, worthwhile在用法上的区别是:(1)worth是介词, 后接动名词或名词，形成介词短语。

接动名词时, 与主语是动宾关系，其形式是主动的，意义是被动的。

如: The book is worth reading. (2)worthy是形容词, 置于be动词后或名词后面, 做后位修饰语, 其结构是: be worthy of doing sth., sth. is worthy to be done。

(3)worthwhile是形容词，要与形式主语it并用：It is worthwhile to read the book. worth和worthy都不能用于这种结构。

worth与worthy是英语学习中常见的两个词，但其用法极易混淆。

现笔者将其用法归纳如下，希望有助于同学们的复习与运用。

一、worth作“值得；值”解时，是一个很常见，但又很特殊的叙述性形容词，通常在句中作表语，并且其后面要求有一个宾语，其宾语可以是名词、动名词或动词不定式。

worth有时也可用作定语。

其具体用法如下：（一）Worth用作表语1. 当句子的主语是物质名词而不是it时，worth后面要求有一个动名词或名词作宾语。

例如：1) The above-mentioned decision is worth studying a little further. 上述决定值得进一步研究。

2) What is happening here today is worth notice. 今天在这里发生的事值得关注。

3) The microcomputer is worth ten thousand dollars. 这台微型电脑值一万美元。

2. 当句子的主语是it而不是物质名词时，可能有两种情况：A. it代表具体东西时，如金钱、物质等，其后接名词或动名词，该名词或动名词是worth的宾语，这时，it既是主语，在意义上又是动名词的逻辑宾语。

例如：1）It is worth saving. 那是值得节约的。

2）It is worth visiting again. 这里值得再一次参观。

3）It (the job) is worth my time.It was worthwhile.The job involves a lot of hard work but it’s ____ it.The job involves a lot of hard work but it’s _____.B. it不代表具体东西时，worth后面一般应加上while，后面接动名词或动词不定式。

这时，it为形式主语，真正的主语为动名词或动词不定式。

接动名词或动词不定式的区别是：while前面有所有格时，一般接动词不定式；没有所有格时，一般接动名词。

例如：1) It is worth our while to use waste materials. 废物值得利用。

2) It is worth while pointing out that heating may bring about certain change in the structure of any material. 值得指出的是，加热会使任何物质的结构发生某种变化。

（二）worth用作定语1. worth不能单独放在名词前面作定语，当它与while构成worthwhile 时则可作前置定语。

这时，worthwhile = worthy。

例如：1) This is a worthwhile book. （该句可改为：This is a worthy book. = This book is worth reading. = This book is worthy of being read. = This book is worthy to be read. ）这本书值得一读。

It is worth our while to read the book. It is worthwhile reading this book.2) It is a worthwhile effort. 这是值得努力做的事。

2. 用作后置定语。

worth放在名词后面作定语时，必须接一个动名词。

例如：1) Tianjin is a city worth visiting. 天津是一个值得参观的城市。

2) This is a question worth discussing. 这是一个值得讨论的问题。

二、worthy是限定性形容词，可以用作表语或定语。

其具体用法如下：（一）worthy作表语1. worthy与of连用时，构成be worthy of，of的后面可以接名词或动名词的被动形式。

例如：1) That is worthy of note. 那件事值得注意。

2) This phenomenon is worthy of being studied. 这种现象值得研究。

2. worthy可与动词不定式连用，动词不定式也要用被动式。

但worthy后面不可再用介词of，须直接接不定式。

例如：1) This problem is worthy to be considered. 这个问题值得考虑。

2) The film is worthy to be seen again. 这部电影值得再看一遍。

（二）worthy作定语1. 作前置定语。

例如：1) This is a worthy English-Chinese dictionary. 这是一本有价值的英汉词典。

2) This is a worthy article. 这是一篇值得一看的文章。

2. 作后置定语时，必须用“worthy of +名词”结构。

例如：1) There is nothing worthy of mention. 没有值得一提的事情。

2) This is behavior worthy of praise. 这是值得称赞的行为。

主语为人：worthy: deservingworthy of admiration;She is not worthy to talk to a man like you.A performance is worthy to be remembered.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.Worth: improtant, good or enjoyable enough to make sb feel satisfied, especially when difficulty or effort is involved.Worthwhile: important, enjoyable, interesting, etc. worth spending time, money or effort on。
