问题补充：

— Did Jerryany magic tricks yesterday?

—No, but he a song.

A. performed; sang

B. performed; sing

C. perform; sang

D. perform; sing

答案：

A. performed; sang

B. performed; sing

(答案→)C. perform; sang

D. perform; sing

解析：perform完成，演奏，表演；sing唱。句意：昨天杰瑞表演了魔术吗？——不，但是他唱了一首歌。结合语境可知上下文描述的是过去发生的动作，故用一般过去时态。当句子中有助动词体现时态时，行为动词一般用原形，故选Ｃ。
