2. worthy可作表语，也可作定语。作定语时意思为“有价值的”、“值得尊敬的”、“应受到赏识的”；用作表语时意思为“值得……的”、“应得到……的”，其后接of sth.，也可以后接to do sth.，例如：
①That is worthy of note. 那件事值得注意。
②This phenomenon is worthy of being studied. 这种现象值得研究。
③This problem is worthy to be considered. 这个问题值得考虑。
④The film is worthy to be seen again. 这部电影值得再看一遍。
⑤This is a worthy English-Chinese dictionary. 这是一本有价值的英汉词典。
⑥This is a worthy article. 这是一篇值得一看的文章。
⑦He said he was not worthy to accept such honour
⑧The school has educated many worthy young people.
⑨The question is not worthy to be discussed again and again.
作后置定语时，必须用“worthy of +名词”结构。例如：
⑩There is nothing worthy of mention. 没有值得一提的事情。
②This is behavior worthy of praise. 这是值得称赞的行为。
③ Something find and rare --- something worthy of the honor of being owned by Jim.
(S3 Unit 10 P84)
注：“worthy of+动名词”与“worth+动名词”在形式上完全不同：worthy of后面接被动式的动名词；而worth后面接主动式的动名词，虽然在形式上是主动的，但其意义仍然是被动的。试比较：
The second-hand house is worthy of being bought. = The second-hand house is worth buying.
The Summer Palace is worthwhile going / to go to have a visit.
Helping old people is a worthwhile activity.
