雅思口语P1 Which stage of your life do you think is the most important(文字版)

The stage of my college life could be the most important in my mind. You know, during that period I had opportunities to know more about the outside world. A brand new life, lots of new friends, teachers and professors or such. My general knowledge of the world wouldn't be limited any more. That is the core. For me, I think I have had some best friends and roommates, till now, they are my best partners of my life. So, that is it.
