Describe something you lost and you got it back
You should say:
When it was
What it was
Where you lost it
How and where you found it
And explain how you felt about it
Last winter, on a normal evening, I went running in the school playground alone. As usual, I put my favorite water bottle on the side with the audience(观众席). . After I ran for five kilometers and did some stretching, I came back to get the water bottle. However, I noticed that the water bottle was nowhere to be found. All I saw was another water bottle which looked pretty similar to mine. Presumably someone must have got it wrong(想必一定有人拿错了). I was upset but all I could do was to go back to the dorm first. I left the other water bottle untouched because I assumed the person who took the wrong bottle would go back to exchange it as soon as he or she found out. I could not call the campus cop just for a water bottle, right? The next day, I returned to the playground at the same time and, guess what? I found that my water bottle had been returned. It must have been sent back by the person who got the wrong bottle. It was like some kind of unspoken agreement(默契). However, I have to change it to a less popular cup next time . Also, if I were the guy who accidentally took another’s belongs, I would at least say sorry. Do you agree?
