If I were given a chance to pick out a word to describe my present life, it is certain that I would choose "busy". Having not been occupied with so many things for a long time, sometimes I introspect, perhaps I am too busy. The pace of my life is too fast. It is almost two months since I came here, at first we didn't have many classes, but now I am not only a student in China University of Geosciences, but also a part-time teacher in Jiangcheng College. Since I seldom spoke loudly in public, I felt very nervous when I gave the first lesson. I knew it was a challenge for me, but everyone should take the first step. Still remember I always heard the question before class when I came to different classes, teacher, are you really our teacher? I said, I am so sorry, I am indeed your teacher. Still remember I blushed now and then in the first class, and felt too nervous to speak. Still remember one day I came to the class, a student exclaimed, asking me whether I made up or not, and then some students echoed, complimented me, actually I didn't make up but I was flattered. Still remember when I sat on the school bus, casting my mind back to the whole day, I felt a little successful. I said to myself, you have made some progress, so good. I know it is a long way to be a good teacher, but I will try my best to better myself.I didn't know from when I began to pursue more than before. This term I even applied to be a member of Public Relations Department, which is a subordinate of the Graduate Student Union. I just had a shot at it, however, it turned out I was admitted. Luckily the PR department is not so busy as other departments, or else I guess I can't handle all the staff because besides this, I need to prepare lessons, do my homework, write papers. Come on! Try to improve myself in every respect. Moreover, Keep fit since the body is the revolutionary qualification.
