(单选题)

What did the author do when his or her mother spoke with Mr. Lee?

A.The author was aiming at a letter on the stop sign.

B.The author was checking the words on the stop sign.

C.The author was choosing the rock he or she liked.

D.The author was in a daze during the talking.

参考答案：A

参考解析：

细节理解题。根据文章第二段第二、三句“She stopped to speak to Mr. Lee. I was busy trying to bulls-eye the ‘O’ in the stop sign with a rock.”可知，作者的母亲停下来和李先生说话，而作者则在全神贯注地用石头瞄准停车牌上的“O”，bulls-eye即对应A项中的aiming at，“O”即对应A项中的a letter。故选A。
