Good_afternoon,_everyone.

Welcome_to_our_school!_ High school students are faced with a choice between arts and science. It was not an easy choice for me to make. After careful consideration, though, I decided on 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 becoming a scientist. Third, my parents wish 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 had a lot to do with my decision.

It is for these reasons that I finally made my choice.
