     I had a interesting dream last night. I dreamed                
that I took part in a race. At first, I could not to run very    
fast and fell behind. So I didn’t lose heart and kept           
running. All the students on the playground cheer me on,          
"Come on!" I was so encouraged that I ran faster and fast     
till I caught up all the other runners. I felt as if flying like

I woke up and found me still in bed!
