B“would+have+done”虚拟语气,表示对过去事情的假设,意思是“本来会做”.
C must have done表示对已发生的事情的推测.
D may/might have done表示对过去某事可能性的推测,意为“可能已经“

A bicycle drivenby electric power中省略了that 定语从句
而整个句子可看成是A bicycle that drivenby electric power becomes quite popular in our city.
还有就是 :要记住 “ ,”前后不能是两个完整的句子
being driven 是正在被骑 to be driven是将要被骑

恩,就这样

1.都是过去完成时,考的是should would must may 的用法,根据句子的意思:无论我们在白天(可能)做了什么事,语气不绝对,可知答案选D
2.用过去分词表示被动语态.
