TOEFL writing part: Is it better to have knowledge of many subjects than specialize in one subject Study is one of the most essential part of people's lives. However, there remains a problem as to whether having broad knowledge of many academic subjects is better than specialize in one specific subject. From my perspective, it is obvious that having knowledge of various subjects is better. First, having other subjects' knowledge can is beneficial to the study of your major. Taking myself as an example, I am a student of chemistry, but when I entered university, I found out that I need to finish the learning of calculus and physics before taking some advanced courses for the knowledge acquired in these elementary lessons are rather helpful for my further study. What is more, the prosperity of interdisciplinary also requires us to know about different subjects, which makes it easier for us to communicate with researchers of other subjects. If we only focus on a specific subject, our study of our major will be largely limited and we may have problem when faced with projects about interdisciplinary. Second, having the knowledge of other subjects can help us develop the creative thinking ability. Getting knowledge of one subject does not only mean gathering information, it also means learning the specific thinking mode. My professor used to ask me to think about how a subject deals with problems and I learned a lot from it. For example, mathematics taught me to think in a logical way and physics instructed me that hypothesis sometimes is a powerful weapon when solving problems. When it come to chemistry, I learned to build models to simplify the problems. In contrast, it may be hard for us to think out of the box if we only learn about a single subject. Third, having a broad knowledge of many subjects can help students to identify which subjects they are really interested in. Not everyone have a clear dream in their mind when they are students, so a broad knowledge of many subject is quite helpful for them to make up their mind. My roommate learned physics first, but he also took part in many other classes. Then, he found out that programming was his 'true love' so he changed his major into computer science. If students only learn about a specific subject, they may loss the chance to meet the subject they really like. Simply put, it is safe to draw the conclusion that having broader knowledge is better. Having broad knowledge, we can definitely harvest more than what we expect.
