You're right. We must not forget cultural points. And even, the differences between these two languages.
OK. You've told that the sentences no.1 & no.2 are very formal and the third is informal. Thus, Which one can I use when talking to a native speaker? According to the word " very formal " I've better use the sentences no.1 & no.2; I'm right, am I not? (or, aren't I ? )
