My undergraduate period will be accomplished (or "I will finish my undergraduate degree") in Baoji university of arts and sciences in July, 2015, I major in philosophy（你的专业） .And now, I am trying my best to obtaining a key (I'm not sure what "key" means in this context) to university which I have desired for a long time.
Well, I want to share some reasons for taking postgraduate exams: First of all, I love my major, it plays an important part in the modernization of our citizens’ thoughts and it really affects me deeply.
