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: ①The above-mentioned decision is worth studying a little further.上述决定值得进一步研究。 ②What is happening here today is worth notice.今天在这里发生的事值得关注。 ③The 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,其后接动名词,该动名词是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: ①It is worth saving.那是值得节约的。 ②It is worth visiting again.这里值得再一次参观。 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: ①It is worth our while to use waste materials.废物值得利用。 ②It 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: ①This is a worthwhile book. (该句可改为:This is a worthy book. = This book is worth leading. = This book is worthy of being read. = This book is worthy to be read. )这本书值得一读。 ②It is 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: ①Tianjin is a city worth visiting.天津是一个值得参观的城市。 ②This 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: 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。 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: ①This problem is worthy to be considered.这个问题值得考虑。 ②The 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: ①This is a worthy English-Chinese dictionary.这是一本有价值的英汉词典。 ②This 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: ①There is nothing worthy of mention.没有值得一提的事情。 ②This is behaviour worthy of praise.这是值得称赞的行为。 注:“worth 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.
