For instance, instead of saying “have a break” native speakers would say “take a break.” Instead of saying “make a crime” native speakers would say “commit a crime.” Instead of saying “wash the dishes” native speakers would say “do the dishes.” It’s not necessarily that the other sentences are wrong, it’s just not how native English speakers talk.
