| C． | what my teacher said | D． | what did my teacher say |
分析 我不明白老师说的话，所以我举起手来问．
解答 答案：C 根据I didn't understand ________，再结合选项，可知是跟一个宾语从句，宾语从句中应该用陈述语序，即主语+谓语，所以排除B，D．再根据宾语从句的时态规律，主句I didn't understand是一般过去时，则从句用过去的某种时态，故排除A．故选：C．
点评 主要考查宾语从句，一定要注意宾语从句的引导词，以及宾语从句的时态和语序问题．把握好这几点，是做好此类题目的关键！就本题而言主要考查宾语从句的时态和语序．
