One day ,my little sister focus her attention on her homework. I let out a yell to frighten her.To my surprise，she was scared and crying loudly.In order to make her happy,I decided to give her my favorite toy.However ,she was still crying .“Peng-” Beautiful fireworks were setting off in the sky .My little sister stopped crying and went out to see it immediately.Besides the mid-autumn festival，we hadnt seen such fascinating fireworks .Finally,cleaners put the residues(残留物）into a big container. what a lovely night !,
