A吧
worth 的用法

worth，worthy，worth-while都为adj. 意为"值得"。
1. worth： be worth + n. 当名词为金钱时，表示"…… 值得……"
be worth doing sth. "……某事值得被做"
The question is not worth discussing again and again.

2. worthy：be worthy of +n. 当名词为抽象名词时表示"……值得……"
be worthy to be done "某事值得被做"
The question is not worthy to be discussed againand again.

3. worth-while： be worth-while to do sth "值得做某事"
worth while： It is worth while doing sth

Answer 2

worthwhile 固定搭配 to be worthwhile for sb to do 值得做某事；to be worth doing；to be worthy of doing 都表示值得做某事；worthily 意为 重要地,可敬地,正当地 没什么固定搭配

各词用法：
