雅思口语P2 Describe something important that you lost in the past(文字版）

Mention about the topic, a special bike which has been with me for years comes to my mind. A couple of years ago, my grandpa bought a bicycle for me as I needed to spend some time on the way to school, actually, there is no specific reasons. My grandpa loves me so much. He got to know that I am a cycling lover. Apparently, he spent 2000 at a time, just gave me this special gift. It could take me to anywhere on the weekends or at the weekdays. Ironically, I lost it somewhere on my campus in autumn, I didn't know how it happened. I just put it in my school as usual, but the other day, I couldn't find it after my school time. I tried to look for it every corner of my school campus. I kept doing this for a couple of times, but I failed. You know, I was like very sad about it, cuz it means a lot to me. What I am trying to say is that I don't care it is a very expensive one, however it is from my grandpa. So, this is what I`d like to talk about. That is it.
