worth,worthy,worth-while都为adj.意为"值得"。worth值,值得。可与其后的成分一起作表语或后置定语,其后一定要有名词或动名词,但不能接不定式。注意:接动名词时,要用主动形式表示被动意义。worth:be worth + n.当名词为金钱时,表示"…… 值得……"be worth doing sth."……某事值得被做" 例:The chair is worth $ 100.这把椅子值100美元。The book is worth reading.这本书值得读。This is a thing worth doing.这是一件值得做的事。The question is not worth discussing again and again. be well worth"很值得",注意不用very哦。例:It is well worth a try.这很值得一试。worth one's while对某人来说是值得做的,对某人来说有益。陆稿主语是动名词或动词不定式,句首用it作形式主语。例:It is worth our while discussing the problem.这个问题值得我们讨论。It is well worth your while to visit the town.那个城镇很值得你游览。worthy:1) 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早山孝的。(2) 与be worth后只接动名词不接不定式不同,be worthy后不接动名词,而接不定式表示被动意义,如:This suggestion is worthy to be considered. 这个建议值得考虑。This book is worthy to be read.这本书值得一读。(3)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,且该动名词若唯困要表示被动意义,要用被动形式。如:He is worthy of filling [=to fill] the post. 这个职位他当之无愧。This suggestion is worthy of being considered [=to be considered]. 这个建议值得考虑。表示“做某事值得”时,用worthwhile 表达,句式如下:worthwhile 用于表示“做某事值得”但习惯上常用形式主语it 位于句首,将作主语的动词不定式或动名词短语后移。It is worth while to discuss the problem again.It is worthwhile discussing the problem again.In my opinion, it's worthwhile having a try at it. 在我看来,这事值得试一试。Is it worthwhile getting angry over such a trifling matter?为这点小事犯得着生气吗?
