Questioning is a bridge to learning.When you begin to doubt something and search for an answer，you will learn.

【参考范文】

It is hard to imagine one can learn without questioning，in other words questioning is a bridge to learning or is the very beginning of learning.Take learning English for example，when we learn the meaning of the phrase “pick up”，our first reaction is what it means and how we can use it.Such a question keeps us going on learning.Then come the following questions: can we find a sentence where we can use it? Or can we find a dictionary to look it up? After the questions being put forward one by one，our actions go further and further，until we get a good command of it at last.So when you are beginning to learn something，don't be shy to ask questions，only with the questions can we have the inspiration to learn something new or do better than before.
