A: “I had to pay ten dollars for this book.”
× B: “It’s probably worthy it.”
请问这个句子的错误何在？
worthy与worth有一个很主要的差别：be worth之后可以直接跟由名词或代词充当的宾语(worth ten dollars)，而be worthy则不能直接跟由名词或代词充当的宾语，而必须通过of:
-
His behaviour is worthy of great praise. (Palmer) 他的行为值得高度赞扬。
-
The teacher is worthy of respect. 这位教师很值得尊敬。
-
That wild theory is not worthy of systematic confutation. 那种毫无根据的理论不值得系统的批驳。
-
Robert, this man is not worthy of the Grail. (Dan Brown, The Da Vinci Code) 罗伯特, 这个人是不配得到圣杯的。(《达·芬奇密码》)
worth 常常用在金钱方面(值……多少钱),而 worthy of 则不能:
-
How much is the picture worth? (Palmer) 这幅画值多少钱?
-
It was worth at least fifty francs. (Bennet) 它至少值 50 法郎。
worth 与 worthy 的其他区别是：
A. worthy 可以用作定语, 而 worth 则无这种用法:
-
The school has graduated many worthy young people. (FWF) 这所学校培养出了许多有为的青年人。
-
He has had a worthy object in view. 他心目中有个崇高的目标。
B. worthy 可以后接动词不定式, 而 worth 却不能后接动词不定式, 参见 worthy to do。
从上面的例句不难看出,你所提问的句子中的 worthy 应当改为 worth。
"What can I do for you, sir?" "I want ____.
A. a dime's worth of candy B. candy a dime's worth worth/worthy of 1732 C. a dime worth of candy D. a dime-worth candy(TOEFL)
