We have worked together in harmony for many years, and I find it with them.

A. worthy of working

B. useless to work

C. worth of working

D. worthwhile working

答案：

A. worthy of working

B. useless to work

C. worth of working

(答案→)D. worthwhile working

解析：考查形容词短语做宾语补足语。固定搭配：be worthwhile doing 值得做某事；be worth doing值得做某事；本题使用了worthwhile working作为宾语补足语对宾语进行补充说明。句意：我们一起和谐地工作了很多年了，我认为和他们在一起工作是值得的。故D正确。
