her leg the last time Brenda decided not to go on the school skiing trip this year.A. B

问题补充：

her leg the last time, Brenda decided not to go on the school skiing trip this year.

A. Breaking

B. Broken

C. To break

D. Having broken

答案：

A. Breaking

B. Broken

C. To break

(答案→)D. Having broken

解析：D 考察非谓语动词。句义：由于上次摔伤了腿，Brenda决定不参加今年学校的滑雪之旅了。题干中句子成分很完整，所以空格处应该使用费谓语动词。本题中非谓语动词走状语，因break与Brenda为主导关系，且Break动作发生在decided之前，因此应该使用现在分词的完成式。故D正确。
