the parents are very strict with their children,so are teachers in school

问题描述:

the parents are very strict with their children,so are teachers in school
这句话为什么不能用so do呢,即:the parents are very strict with their children,so do teachers in school

因为是teachers ARE very strict with their children,too.
恢复一下就看出来了
are是be动词
do是助动词,可以是
---I Like playing
---So do I = I LIKE playing,too
like动词用助动词do来带
