It was right in front of a truck's tire. Without thinking I got out of my car，held my hand up so the truck driver wouldn't move forward, and bent down to look at the butterfly. I found one of its legs was stuck in what looked like soda(宾语从句). I reached down and cupped the butterfly in my hands as gently as I could. I lifted its leg up and suddenly it was free. I spread my hands and up flew it towards the blue sky(倒装). My eyes shone brighter and heart felt lighter as I watched it(as引导时间状语从句). $$
