I was walking down the road one day when my cellphone rang. I heard a little girl on the other end 36 ,“Dad, please come back soon. I miss you so much!” Because I just have a little 37 , I knew it was a wrong number. So I rudely 38 “you’ve dialed the wrong number!”and then 39 . During the following days, I got the same call 40 .But I didn’t care much about it. Then one day she contin  ually called me, 41 I didn’t answer. In the end, I answered the phone and heard a torpid(有气无力的) voice, “ Dad, please come back. I miss you so much! Dad , I m 42 so much pain! Mom said you were too busy to take 43 of me. But, Dad ,please 44 me again, OK?” The kind of 45 was difficult to reject. I made a loud kiss on the phone and heard the 46 voice say, “Thank you … Dad , I am so … happy…”Shortly after this, I became 47 about who had been on the other end of my phone. So I called back, and a woman answered, “Sorry, sir. I am really sorry to have 48 you. My daughter has suffered from bone cancer 49 she was born. And her father … died in a(n) 50 last week. I 51 not tell her the news. Po  or baby. When she couldn’t 52 the painful chemotherapy(化疗), she would cry for her dad, who had always 53 her. I really cou ldn’t bear it, so I gave her a random(任意的)phone number …”“How is your daughter now?” I couldn’t 54 to ask. “She has 55 . You must have kissed her on the phone, because she went with a smile,” she said, “and I am glad that she gets rid of the pain and stays with her father forever.” I couldn’t keep my tears back.
