worth, worthy, worthwhile在用法上的区别
一、从句法功能上看
worth 通常只用作表语，不用于名词前作定语；
worthy 和worthwhile 可用作表语和定语。
It isn’t worth the trouble. 不值得费那个事。
He is a worthy gentleman. 他是位值得尊敬的绅士。
His behavior is worthy of great praise. 他的行为值得高度赞扬。
They achieved a very worthwhile result. 他们取得了很有价值的成果。

得，因为我们把票买到了。
二、从所使用的修饰语来看
worth 习惯上不用very 修饰（要表示类似意思可用well），而worthy 和worthwhile 则可以
用副词very 修饰。如：
That is very worthy of our attention. 那件事很值得我们注意。
Nursing is a very worthwhile career. 护理工作是很值得干的职业。
但习惯上不说：The work is very worth doing. （very 应改为well）
