单选题Like all other mothers who have small children, I, too, have to steal time--from my own children at home and from the children who know me as their teacher--just to put a few words down on paper. Many times I"ve wanted to write for myself, for other women, for my parents, for my husband, and especially for my children. I would have liked to leave a legacy (遗产) of words explaining what it has meant to have twins (双胞胎). One reason there is not a great deal written about being a mother of a new baby is that there is seldom a moment to think of anything else but the baby"s needs. With twins, I did not have a spare hand to write with. Before my twins were born, my days were long and I had nothing to write about. After the twins" birth I did have something to write about, but I found myself facing not a pen and paper but milk bottles. Some nights, friends would visit. They would leave at 11 p.m. , heading for bed, and for us the night was only just beginning. With twins, there is really no night. Each feeding lasts a long time. At 1: 00 a. m. , each of them would begin crying from hunger. At 4:00 a. m., when I finally put them down, I head for the kitchen and light a cigarette. I haven" t smoked in almost a year, but I feel I"ve never needed it more. I"m so sleepy and so tired that I don"t care. Two years have passed since then and we"ve managed to live through k ail. My days are still very full and even now there isn"t one evening when I put the twins down for the night that I don"t breathe a sigh of relief(松口气). At last a little time for myself.
