Absolutely! Adapting and diversifying his boxing techniques could make a significant difference. By using a variety of strategies, he can stay unpredictable and adapt to different opponents, potentially increasing his success in the ring. Being versatile is a valuable skill for any boxer.
Here’s a corrected and improved version of your sentences:
"That's right, I agree with you. If he can change his mind and adopt a different boxing style, I think he could win more and perform much better."
Tips for improvement:
1. Use "adopt" instead of "use" when talking about styles or methods—it sounds more natural.
2. "Change his mind" is correct, but you can also say "change his approach" for more variety.
3. Instead of "win more, he can do much more better," combine the ideas smoothly: "win more and perform much better."
4. Avoid double comparatives like "more better"—simply say "better."
Keep practicing by linking ideas clearly and using precise words!
