问题补充：
- What do you suppose made Alice so sad?
- the computer test.
A. Because she hadn’t passed
B. For she didn’t pass
C. She failed to pass
D. Her failing to pass
答案：
A. Because she hadn’t passed
B. For she didn’t pass
C. She failed to pass
(答案→)D. Her failing to pass
解析：考查句子和短语，问句的意思“你认为什么事使她如此悲伤？”，问得是哪件事而不是原因，A、B、C都是句子，说得都是原因而不是一件事，所以选D，句子意思“她没有通过计算及考试”
