"我在八岁的时候真正成为了蝙蝠侠的铁杆粉丝 我相信如果我认真学习并努力锻炼 我就能成为这个人"

Simplified Meaning:

When someone says they became a big Batman fan at a young age and believed they could become like Batman by studying and exercising a lot, it means they were really inspired by Batman and wanted to be like him. Batman is a superhero who doesn't have superpowers; instead, he uses his intelligence, physical strength, and determination to fight crime. Imagine a kid who dreams of being strong and smart like Batman—so they decide to read books to get smarter and start working out to get stronger. This shows that heroes in stories can motivate us to improve ourselves. For example, someone might be inspired by a famous athlete and start practicing sports to get better at them. By working hard and staying dedicated to their goals, like the person who wanted to be like Batman, anyone can make positive changes in their life and achieve great things. This idea encourages us to set strong goals and work diligently to reach them, no matter how big or small they are.
