2.请按如下格式在相应位置作答。I walked up to the stage and began to show my tricks.I put my heart in it more than anything else I had everdone.To make the kids laugh,I made funny faces while telling jokes.I made a balloon animal-a cute rabbit-and I even managed to make it disappear and then reappear in the arms of that little boy.Those smiling faces ofhappy children,especially his,battling with their lives channelled a new energy within me.After that day,my career as a joker peaked.I was called to various shows;my videos went viral on theInternet;I paid all my debts.My life had blossomed just like the roses which grew outside the hospital gate.Allof this happened because of that boy in the wheelchair.I decided to pay him a visit once again with some toys anda bunch of flowers.I asked the nurse about the boy.The nurse's eyes lit up,filled with joy,and she said in a lighttone,"Sir,the boy you want to meet was found cancer free after the recent screening tests after your show andhe's been discharged from hospital.It was a miracle."
