Abstract

To begin with this question, how to define the concept “subject” is very important. Subject should be a particular small area of knowledge that can be distinctively separated from other knowledge. If a description of knowledge cannot be clearly defined as knowledge in which area, then such knowledge couldn’t be said to be included by a subject. For example, sine rule and cosine rule are definitely knowledge in math region: that can be clearly defined; while the chain reaction could be classified in both physics or chemistry, so we won’t be discussing such knowledge in our essay. When people ask a question, the answer to the question is thought. The answers to some questions are very obvious. The purpose of asking questions is to express the emotion of the questioner; And the answers to some questions are really very complex. Maybe human beings can't understand them now, so the purpose of asking questions is to let people think and explore together, and finally find more results. In either case, we are trying to make everything better by asking questions. Maybe this improvement will not be shown immediately, but each of our questions will bring more benefits at a certain time after asking questions. That's why we ask questions.
