WORTH的用法
壹)Worth用作表語 1.當句子的主語是物質名詞而不是it時,worth後面要求有壹個動名詞或名詞作賓語。例如: ①The above-mentioned decision is worth studying a little further.上述決定值得進壹步研究。 ②What is happening here today is worth notice.今天在這裏發生的事值得關註。 ③The microcomputer is worth ten thousand dollars.這臺微型電腦值壹萬美元。 2.當句子的主語是it而不是物質名詞時,可能有兩種情況: A. it代表具體東西時,如金錢、物質等,其後接動名詞,該動名詞是worth的賓語,這時,it既是主語,在意義上又是動名詞的邏輯賓語。例如: ①It is worth saving.那是值得節約的。 ②It is worth visiting again.這裏值得再壹次參觀。 B. it不代表具體東西時,worth後面壹般應加上while,後面接動名詞或動詞不定式。這時,it為形式主語,真正的主語為動名詞或動詞不定式。接動名詞或動詞不定式的區別是:while前面有所有格時,壹般接動詞不定式;沒有所有格時,壹般接動名詞。例如: ①It is worth our while to use waste materials.廢物值得利用。 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,加熱會使任何物質的結構發生某種變化。 (二)worth用作定語 1. worth不能單獨放在名詞前面作定語,當它與while構成worthwhile時則可作前置定語。這時,worthwhile = worthy.例如: ①This is a worthwhile book. (該句可改為:This is a worthy book. = This book is worth leading. = This book is worthy of being read. = This book is worthy to be read. )這本書值得壹讀。 ②It is worthwhile effort.這是值得努力做的事。 2.用作後置定語。worth放在名詞後面作定語時,必須接壹個動名詞。例如: ①Tianjin is a city worth visiting.天津是壹個值得參觀的城市。 ②This is a question worth discussing.這是壹個值得討論的問題。 二、worthy是限定性形容詞,可以用作表語或定語。其具體用法如下: (壹)worthy作表語 1. worthy與of連用時,構成be worthy of,of的後面可以接名詞或動名詞的被動形式。例如: ①That is worthy of note.那件事值得註意。 ②This phenomenon is worthy of being studied.這種現象值得研究。 2. worthy可與動詞不定式連用,動詞不定式也要用被動式。但worthy後面不可再用介詞of,須直接接不定式。例如: ①This problem is worthy to be considered.這個問題值得考慮。 ②The film is worthy to be seen again.這部電影值得再看壹遍。 (二)worthy作定語 1.作前置定語。例如: ①This is a worthy English-Chinese dictionary.這是壹本有價值的英漢詞典。 ②This is a worthy article.這是壹篇值得壹看的文章。 2.作後置定語時,必須用“worthy of +名詞”結構。例如: ①There is nothing worthy of mention.沒有值得壹提的事情。 ②This is behaviour worthy of praise.這是值得稱贊的行為。 註:“worth of+動名詞”與“worth+動名詞”在形式上完全不同:worthy of後面接被動式的動名詞;而worth後面接主動式的動名詞,雖然在形式上是主動的,但其意義仍然是被動的。試比較: The second-hand house is worthy of being bought. = The second-hand house is worth buying.
