樱漫

关于as承前相似助动词补出的问题很头疼，下面我找了几句话，有3句自己补出来了，不知道对不对，还有‘？’代表我不会补。。。。大家一起来看看。。。。。。。。。
1) You eat two apples, as do I.
2) You are punished, as (?) I.
3) He is punished, as (?) I.
4) You are eating dinner, as (?) I.
5) He is eating dinner, as (?) I.
6) He had been punished, as had I.
7) He had finished the work, as had I.

帮你顶，我也不懂~~如果是被动的话，助动词不用补出吗？
我觉得像6的话应该是as I had been吧
