Having won the first place in the English examination, Tom ran back home, .A. happy and ex

网友回答

(答案→)A. happy and excited
B. happily and excited
C. happily and excitedly
D. happy and excitedly
解析：词义辨析。And连接的两个词语一般要求词性相同，happy形容词高兴的；happily副词高兴地；excited形容词兴奋的；excitedly副词兴奋地。形容词短语状语相当于状语从句或并列句，修饰的是句子的主语。故选A。
