As we all know, questioning can lead to searching for an answer. If we are in the habit raising doubts as to whether that we are told is true, we can find the correct answer and learn more.
Two years ago, our teacher offered us an answer to a difficult math problem in class. Although the answer seemed a little strange, but nobody except me doubted it. Think that his answer might be wrong, I carefully analyzed the problem and tried to work them out in a different way. Half a hour later, I managed to find the correct answer. When I showed my answer to him, the teacher praised me as my independently thinking.
From this experiences, I have learned that questioning can serve as a bridge that help us to seek the truth.
