要大胆创新该怎么说英语

To be bold and innovative in English, you could say "be daring and take risks" or "think outside the box." You could also say "be bold and try something new" or "venture into uncharted territory." Another way to express this idea is to "push the boundaries" or "break the mold." All of these phrases suggest that you are willing to try new and different approaches, and that you are not afraid to take risks in order to achieve your goals.
