1.形容词exciting和excited都表示激动、兴奋的意思。
excited表示“兴奋的”，指人、物对......感到兴奋；
exciting表示“令人兴奋的；使人激动的”，指人、事、物本身让人兴奋、激动。一般情况下作表语时，通常人做主语，用v-ed；物做主语，用v-ing.同样的道理，其他类似的词：
surprising/surprised；
interesting/interested；
amusing / amused;
boring/bored;
astonishing/astonished;
tiring/tired;
terrifying/terrified；
worrying/worried;
satisfying/satisfied等也是这样区分的。它们作表语比较好区分。

2.exciting的基本意思是“使人兴奋〔激动〕的”,具有主动意义,一般只修饰无生命的事物。在句中可用作定语或表语。难点就是它们作表语时的选择。

excited作定语时，本来是指“心情激动的”，an excited talk 心情激动的谈话
excited本来是描述人的感受的，在这里把它转移到了谈话上了；
an excited look/expression心情激动的表情
an excited man心情激动的人
an excited voice心情激动的语调（发音）
像这些-ed修饰的短语是描述其逻辑主语本身的某种感受的；如果你硬要说：an exciting voice令人心情激动的语调，含义是这语调让（令）别人心情激动的。其他短语也可以类似分析。如：
She took a deep breath to calm herself, but her voice still sounded excited.
她深吸了一口气，让自己平静下来，但她的声音听起来仍然很激动。
