Autumn is here in campus. Trees thick with green leaves have turned to red before we knew it. However, there is no one interested in it. As mid-term exams, study and career take up all of us, so we do not know that autumn is here. How about turning your eyes to autumn colors on campus every where and high and clear sky? It is already passed autumn and going to winter. And then we should enjoy autumn because it is not much longer. Autumn has disappeared because of global warming. Someday, the day we want to get sentimental about autumn, might not come even if we want to have autumn. Therefore, let's enjoy this autumn right now.
