论文部分内容阅读
一、worth 是表语形容词，后接名词、代词或动名词。有时也可作名词用。
1. Would you please make up a topic worth _______ in tomorrow’s conference?
A. discussing B. to be discussed
C. to discuss D. being discussed
解析：worth作后置定语，修饰a topic，worth 后接动名词的主动式表示被动含义。上句可改为：Would you please make up a topic which is worth discussing in tomorrow’s conference？故答案是A。
2. They bought ten thousand dollars’ worth of equipment.
二、worthy 作定语修饰名词时表示 “有价值的、可敬的”。并且修饰worth和worthy都用well而不用very。
We should live a well worthy life.
She is a worthy teacher.
be worthy 后可接不定式的被动式；如be worthy与of 连用，后可接名词或动名词的被动式。
The article is worthy to be studied carefully.
The article is worthy of careful study.
The article is worthy of being studied carefully.
三、worthwhile 意为“……是值得（花时间和精力）的”；用it 作形式主语，后面可接动名词或动词不定式。
It is worthwhile reading the novel.
It is worthwhile to read the novel.
上面两句可改为：
Reading the novel is worthwhile.
To read the novel is worthwhile.
四、另外 worth one’s while 也是常用短语,可用句型 “It is worth one’s while... ”，后可接动名词或动词不定式，意为 "值得某人干什么"。
