阅读下面短文,从短文后的选项中选出能填入空白处的最佳选项。选项中有一项为多余项。In a video, someone cuts open a coconut(椰子),pours its juice and takes away meat in about five seconds. What does it take to master a skill like that? Many people see it as a rule that says," Just spend a lot of time practicing. " Many studies have shown that to improve our skills,we cannot just practice, but must use " deliberate(刻意的)practice" . So what is deliberate practice? Imagine you want to become a professional violin player. You can already play some great pieces. Do you get better by only playing those same pieces over and over again? Or do you try to learn new songs? " Deliberate practice" is different from" common practice" . It requires feedback(反馈)and constant(不断的)challenges to yourself. Teachers can find mistakes and make corrections. But they cannot be there for us every step of the way. So we must be able to provide our own feedback and learn from our own mistakes. If you are a runner who can run 100 meters in 12 seconds, you can try to achieve the same success in 11 seconds or even 10 seconds. Even if you are already the best in the world at something, your goals to challenge yourself and do better should never disappear. " Professional" coconut openers can complete their tasks in five seconds. The only difference between them is that professional openers make efforts to constantly improve themselves, while others are just continuing to" practice" . A. But it is not the real reason. B. Constant challenges are pretty easy. C. There are others who take much longer. D. They offer us something that we need. E. Do you also record yourself and listen for mistakes? F. Feedback commonly comes from teachers and ourselves.
