英语作文：我想成为一名科学家

I really want to be a scientist. I think the scientist is the best job for me. A good scientist can make the world change a lot. If I become a scientist, I will make the desert be coverd with green trees and grasses, make the war never take places and so on. Now, although I am only a middle school student, I am interested in math and physics. Maybe I have a little of creativity. I will study science harder and harder. I believe that "There is a will, there is a way! "
