选择题
Li Gang, a police officer, said that little about what his son _____ he know the moment all the media reported the traffic accident _____ in Hebei University．
A．did do; happened
B．would do; happening
C．could do; happened
D．did did; happening
答案
答案：D
题目分析：考查时态和分词，由said可以知道是一般过去时，所以是did，what his son did意思“他的儿子所做的”，分词 happening做名词the traffic accident的后置定语，名词the traffic accident和动词happen是主谓关系，所以用现在分词做后置定语
点评：做时态题时，首先看时间状语，由时间状语确定句子的时态；如果没有时间状语，则从句子暗含的意思确定句子的时态
