Hello, everyone. My name is Eric and I come from Taiwan. I am twenty-two years old and a student at National Taiwan University. I was born on May 22; coincidentally, my father was also born on May 22, forty-four years ago, which means my father is twice my age/twice as old as I am /twice older than I am. I major in International Leadership because I have an ambition to change the world and make it a more peaceful place. The department I am enrolled in has only thirty students, and most of the other departments have about four times the number of students/four times as many students/four times more students, which means they have 120 students on average. I take as many classes as I can because I desire to learn more. Therefore, I have to spend a lot of time on my schoolwork every day, many times the amount of time/many times as much time as/many times more time than my friends spend on their schoolwork, as most of my classmates spend very little time on their schoolwork every day. I am very happy with what I am doing and I want to keep doing it.
