这两个词都可以用作名词和动词，作名词时，意义相近，但不是同义词。
作名词时，award的意思是“奖品”、“奖金”，其义与prize近似，两者都指因为作出杰出成就而受奖。例：
the olympic winner received a gold medal as an award．he won the second award of $ 2，000．
而reward作名词时，其意为“赏金”、“酬金”或一些非金钱的报酬。例：we will offer a reward of ten thousand dollars for information about the case．如果有人提供有关案件的情报，我们愿意出一万元赏金。
we don't expect substantial rewards．我们并不期望得到优厚的报酬。
用作动词时，award的意思是“授与”、“颁发”、“判给”；reward则表示“报答”、“酬谢”之意。例：
he was awarded the first prize for outstanding industrial design．他获杰出工业设计一等奖。
we judge awarded him twenty thousand dollars as damages．法官判给他二万元作为赔偿费。
you should reward them according to their deserts．你应该对他们**行赏。
is that how you reward me for my help？你就是这样来报答我给你的帮助吗？reward也可以用于比喻意。例：
i would feel amply rewarded if my book—a study of english twins—could be of some help tothe readers．
如果我的书《英语学生词语之研究》对读者有所帮助的话，我就感到心满意足了。
