Question

【题目】Bob took a photo of his girlfriend while she _________ at the party.

A. dances B. was dancing

C. has danced D. is dancing

Answer 1

【答案】B

【解析】

试题分析：句意：鲍勃的女朋友正在聚会上跳舞，他给她拍了一张照片。Dances一般现在时第三人称单数形式；was dancing过去进行时形式； has danced现在完成时形式； is dancing现在进行时形式。联系Bob took a photo of his girlfriend可知该用过去时。所以选B。
