We ( ) in the river near our village when we were little girls. A. used to swim
B. used to swimming C. are used to swimming D. were used to swim

答案为A。本题考查判别形似的短语。used to do “过去常做”，仅此一种时态。be used to do“被用于做”，是use的被动语态，时态多变。be usedto doing “习惯于做”， to是介词，时态多变。因此可看出B是错误的搭配；C是时态错误；D错在介词to后没有用动名词形式，故A正确。
