Question

【题目】He was too busy online anything dangerous on the road while walking.

A. chatting; to notice B. to chat; to notice

C. chatting; noticing D. to chat; noticing

Answer 1

【答案】A

【解析】

句意：当他走路时，他太过忙于在线聊天而不能注意马路上的任何危险。选项中的notice为实义动词“注意”，根据语境可知本题考查短语be busy doing sth“忙于做某事”与too…to…“太…而不能…”，故答案应选A项。
