参考答案：B
Every night, my mother would come to my room, lean down and push my long hair out of the way, then kiss my forehead． I don't remember when it first started 26 me --her hands pushing my hair that way. But it did make me annoyed, for they felt work - worn and 27 against my young skin．Finally, one night, I shouted at her: “Don' t do that any more --your 28 are too rough！" She didn’t say anything in 29 ．But never again did my mother close out my day with that _30 expression of her love． Time after time, with the 31 years, my thoughts returned to that night． I'm not a little girl any more．Mom is in her mid - seventies, and those hands I 32 thought to be so rough are still doing things for me and my 33 . Now, my own children are 34 Mom no longer has Dad．It was late on that Thanksgiving Eve, as I went to sleep in the bedroom of my youth, a familiar hand 35 before stealing across my face to brush the 36 from my forehead．Then a kiss, ever so _37 touched my brow．In my 38 , thousands of times, I 39 the night my young voice complained．40 Mom's hand in my hand, I said how 41 I was for that night．I thought she'd remember, as I did,_42 Mom didn't know what I was talking about．She had forgotten—and 43 —long ago． That night, I fell asleep with a new 44 for my gentle mother and her caring hands． And the 45 I had carried around for so long was nowhere to be found．
