参考答案：B
She was a four-year-old girl with very fine golden hair when I first met her．She was carrying a bowl of 1 ．I was 29 at the time and suffering from the flu． Her mom and I had been friends for many years．Finally that friendship grew into care，from care into 2 and marriage．Marriage brought the three of us together as a 3 ．At first，I was afraid to be a“stepfather”.Therefore，I tried not to come between my future daughter and her 4 father．I acted in that way in order to be liked．However， 5 she was growing up, I found it increasingly hard to 6 with her． Once her school required every parent to write an open and 7 letter to the children．I wrote a letter about a little golden-haired girl who had brought me a bowl of soup when I needed 8 ． A week later，all the parents got together with our children in a classroom．The students were allowed to make a few speeches．I was 9 to hear what my daughter would say． Finally，my daughter determinedly 10 her way up to the microphone．She said something like others and then 11 ."There are people and things we sometimes take for granted that we shouldn't，at this very moment，I just want to say…I love you，father．” Immediately people around me started 12 at me，and patting me on the back as though they also understood the depth of that unusual speech．For a teenage girl to say 13 in the front of a room full of people，“I love you”，took a great deal of courage．Since then I have come to understand that I didn't need to have any 14 about being a stepfather．I can still 15 honest love with the same little girl I met so many years before-carrying a bowl full of what turned out to be kindness．I can also be friends with the girl-my dear daughter．
