I don't intend to skip any important part of the sentence, (at least not on purpose) but when my grandson was learning French, he thought it contained a double negative, and because he had learned to not do that in English, he wondered why it was o.k. in French.
Is all.
I used to teach remedial writing classes in the English department as well as my current department (Modern Languages), so these students were native speakers of English. Sometimes students who are bilingual but would probably have been better off in the ESL classes were placed in those English dept along the native speakers. Most of the teachers were able to handle it just fine, but some teachers just couldn't figure out what to do with students who also spoke another language.
I was scoring exams one semester and another adjunct sitting at the table with me just blurts out, "What is with these ESL students? Can't they learn vocabulary?" I asked him what he meant. "Well, they have the same grammar, why can't they just learn the English words to put in the sentence?"
Dude thought that every language in the world had the same grammar, just different words. I think I did a decent enough job at not being too witheringly sarcastic, but I don't think I was able to entirely keep the "you're a moron" tone out of my voice.
