The main difference is how well we understand things. If we learn skills by ourselves, we get basic ideas from books or online. But if someone is there to show us exactly what to do, we understand much better. For example, we can watch a cooking video online, but it might not turn out perfect. However, if someone is there to guide us, it's harder to make mistakes.
主要区别在于我们理解事物的程度。如果我们自己学习技能,我们可以从书籍或网络中获得基本的概念。但是如果有人在场确切地告诉我们该做什么,我们的理解会更深入。例如,我们可以在网上看一个烹饪视频,但成果可能并不完美。然而,如果有人在那里指导我们,犯错误的可能性就会小得多。
