It is not an easy choice for me to make. After careful consideration, though, I decide to choose science as my main subject of study. The reasons are as follows.　　First, science graduates are in greater demand than arts ones in China. Second, the science major can help me achieve my childhood dream of being a scientist. Third, my parents want me to study science at college because they believe I will have a brighter future as a science student. Last but not least, my physics teacher is my role model, whose influence on me has had a lot to do with my decision.It is for these reasons that I will make my choice.　　Thanks!13
