“worth”和“worthwhile”的区别是什么？

Worth 与Worthy 

1. worthy 可作定语,worth不能 He lived a worthy life.

2.worth 可接表示价值的名词或短语,worhty 不能. The house is worth 100,000 pounds. 

3.worth 可接名词作宾语,worthy须加上of才能接名词. .The matter is worth( worthy of)consideration. 

4.worth 接动名词的主动式,worthy 接动名词的被动式. The museum is worth visiting.=The museum is worthy of being visited 

5.worthy 后可接不定式,worth不能. The lesson is worhty to be remembered. worthwile 系表形容词 It is worthwhile.It is worthwhile taking the trouble to explain a job fully to new employees.

1. worth是一个只能作表语的形容词，意思为“值……的”、“相当于……的价值的”、“有……价值的”、“值得……的”。后接名词、接动名词的主动形式。例如：

This second-hand car is worth $2000 at the most.

The exhibition is worth a visit/visiting.

It’s not worth getting angry with him.

The question is not worth discussing again and again.

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.

worth 不可单独作谓语（It is worth doing sth 除外）
worthwhile=worth while 可以单独作表语。
如：
这个问题值得考虑
The problem is worth considering. (不用worthwhile)
It is worth considering the problem. (可换用worthwhile)
It is worthwhile to consider the problem(不用worth)
To consider the problem is worth while (不用worth)
Considering the problem is worth while (不用worth)
