■ dissatisfied 与 unsatisfied

两者的区别是：unsatisfied 通常指“愿望”、“要求”、“好奇心”之类，而且往往经过一个过程后仍然得不到满足。

• … a large unsatisfied demand for education at university level. (Times Literary Supplement, Feb. 5, 1970)…大量得不到满足的要受大学教育的要求。

Dissatisfied 则是静态的“心怀不满”，而且主要指人。

• ... the young adult is dissatisfied more often with the job than the older worker. (Dale B. Harris, Automation, Education and Human Values)…年轻的成年人比年长一些的工人，对工作更为不满意。
