选择题
--Did you listen to the report last Friday?
--- Yes, it was about the shortage of migrant workers. That was the first time I______ about the subject.
A．heard
B．was hearing
C．would hear
D．had heard
答案
答案：D
题目分析：考查动词时态。句义：你听上周五的报告了吗？是的，是关于工人的短缺的，那是我第一次听到这个主题。把握关键短语hat was the first time，构成固定句型this/that/it was the first time + 主语 + had done ，所以D正确。
