worth的用法

◆犯不上跟她生气。 误:

She's not worth to get angry with. 正:

She's not worth getting angry with. 析:

(be) worth后接动词时,该动词不能用不定式,而用动名词。注: 这类结构在现代英语中也可改用形式主语it,如上面的误句也可改为:

It isn't worth getting angry with her.再如:

The film is worth seeing. / It is worth seeing the film.(这部电影值得看)。

◆这本书很不错,值得再读一遍。 误:

The book is excellent.It's worth reading a second time. 正:

The book is excellent. It's worth being read a second time. 析:

(be) worth后接动名词时,即使该动名词具有被动意味,也总是用主动形式。

◆这个博物馆值得你去看看。 误:

2 / 6

You are worth visiting the museum. 正:

It is worth your while visiting [to visit] the museum. 析: 如以上两例所析,worth后接动词时要用动名词,但是注意这类结构有以下特点:

①句子主语通常就是其后动名词的逻辑宾语;②若句子主语不是其后动名词的逻辑宾语,那么其主语就应是形式主语it。另外注意:

与worth后接动词必须用动名词不一样,worth(one's) while后接动词时可用动名词也可用不定式(且这类句型的主语通常是形式主语it)。

◆这个计划很值得一试。 误:

The scheme is very worth a try. 正: The scheme is well worth a try. 析:

要加强worth的语气,习惯上不用very,而通常用well。 ◆这台脑不值你付的那些钱。 误: 正: 析:

value=价值(是名词),valuable=有价值的(是形容词),两者均不

能后接what从句。关于worth(值得...的)的词性:

有的语言学家认为是形容词,而有的语言学家(如R.Quirk等)则认为是介词(可以支配名词短语、支配带逻辑主语的动名词以及what从句)。worth worthy worthwhile的用法

1.worth adj&n.值得,应该,作形容词在句中只能作表语 ①sb./sth. be worth ... :

His words are worth notice.他的话值得注意. The bike is worth 200 yuan.

②be (well) worth doing (很)值得做...,注意这个句型是主动表被动的用法,如这本书值得一读This book is worth reading. 2.worthy adj&n.有价值的,值得...的,做形容词时既可以做表语又可以作定语 ①be worthy of +n. He is worthy of our praise.

②be (quite)worthy of being done (很)值得做... : The film is worhty of being watched.

③be worthy to be done (很)值得做... ,上面的句子可以改写为: The film is worthy to be watched.

3.worthwhile adj.值得做的..值得出力的,既可以做表语又可以作定语

be worthwhile doing/be worthwhile to do:

It is worthwhile discussing the question again.=It is worthwhile to discuss the question again.worth意为“值……的,有……的价值的”等,常常用作形容词,在句中一般作表语,有时也可用作定语,如:

4 / 6

aplaceworth seeing(值得一看的地方),adictionaryworth$50(一

本值50美元的词典)等。

worth用作表语时,不能单独使用,其后通常接动词的-ing形式,而不能接动词不定式。常用的句式有:

1. “主语+be+worth+动词的-ing形式+……”此时,句子的主语就是worth之后动词-ing形式的逻辑宾语。例如: Now John is worth talking to.(现在值得与约翰谈一谈。) He isn ' t worth getting angry with.(犯不上跟他生气。) 注意:

动词的-ing形式之后的介词不可省去。worth后面的动词-ing形式一般用主动形式表示被动意义,而不能直接用被动形式。试比较: 正:

The film isn ' t worth seeing. 误: The film isn ' t worth being seen.

2. “It(形式主语)+be+worth+动词的-ing形式+……”例如:

I ' t isn ' t worth repairing the bike.(这辆自行车不值得修理了。) Is it worth visiting the city?(这个城市值得参观吗?) 一般来说,worth前面可用well,really,very much,hardly,easily等词语修饰,但一般不用very修饰。例如: This is really worth doing.(这确实值得一做。)

He has something very much worth saying.(他有些话很值得讲。)

请比较:

正:

This book is worth reading. 正: It is worth reading this book. 正: This book is well worth reading. 误: Reading this book is worth. 误: This book is worth being read. 误:

This book is very worth reading. worth的下列用法也值得注意: (1)表示“值(多少钱)”的意思时,其后主要接表示钱数或类似的词语。例如:

This picture is worth 100 yuan.(这幅画值100元。)

A bird in the hand is worth two in the bush.(双鸟在林不如一鸟在手。)(谚语)

(2)表示“值得”的意思,后接某些名词。例如: His words are worth notice.(他的话值得注意。)

Is it worth all the trouble?(费那么多事值得吗?)

6 / 6

(3)表示“拥有……价值的财产”的意思。例如:

He is worth a million dollars.(他拥有百万家产。)

(4)用作名词,表示物质、精神等方面的“价值”时,worth是不可数名词,如a picture of great worth(一幅价值昂贵的画),a man of worth(很有价值的人)。

(5)用在一些习惯用语中,如for all one is worth(尽力,尽量地),for what it ' s worth(不论真伪),worth one ' s salt(胜任的,称职的,值得雇佣的)worth somebody ' s while(值得某人花精力[时间]的)。
