It's a little hard to understand what you want, however, in English we often give two choices to someone: would you like a: or would you like b: Sometimes they can be opposite in meaning, such as do you a: like honey, b: not like honey. Sometimes it can just be a personal choice, such as: would you like to a: go to the park, or b:go to the shops? I hope this helps. Pauline (italki teacher and English native speaker)

"What are some expressions that sometimes mean one thing and sometimes mean the opposite?" Well, with sarcasm, things can mean the opposite, eg: 'That's great!' can be 'Oh no.. that's terrible!' ha ha
