I want to ask how to justify whether this omisson in SC is correct.
I know since Ron once said that in parallelism, if the verb in the second part is absolutely the same as in the first part of it then the verb could be omitted.
From prep, I know such principle require both verb tense and the verb must be same.
But if the voice is different, I mean in the first part is passive, but inthe second is active, can I use such principle in judging?
Besides this, can some one tell me are there some principles about omittion like Ron's words.
