Re: Are the two words of speaking and grammar parallel?
I'm a strong proponent of parallelism because it doesn't lead readers down blind alleys. However, I have no problem with the sentence that HV posted above, because the parallelism comes from "He was told to report ... and (he was told) that he would find..." The parts that follow are both what he was told.
Yes, gerunds act like nouns, but they are not completely nouns. I don't like this sentence either: "I like swimming and crossword puzzles." I would write it as "I like swimming and doing crossword puzzles."
T, I'm curious: Do you object (aside from the discontinuity of the attributes) to something like this? She was happy, well-educated, and a good swimmer.
Oh - and of course, we're talking style, not grammar. "Correctness" is something we all struggle with on this forum when learners produce sentences that are grammatically correct but not natural and/or not what we consider good style.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
