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 "Where is a will,there is a way!"(翻译）
