Tom, what did you learn at school today?
—Our teacher told us __________________________________.
Awhat had happened to dinosaurs
Bwhen did we send up Shenzhou Ⅺ
Cwho the first man was to land on the moon
D
why light travelled faster than sound
我觉得应该是A吧。
因为前面的told表明说这话的时候是过去时,而老师说的是在那时后的,应该是过去的过去,应该用过去完成时。
故该用had done 的形式。
(打字不容易啊,望采纳)
这是宾语从句,主句一般过去时,从句用过去的某个时态
陈述语序所以BC排除
D是客观事实要用一般现在时
A正确,理由同楼上。
