阅读下列短文，从每题所给的四个选项（A、B、C和D）中选出最佳选项.①Every Saturday night Mama would sit down by the kitchen table and count out the money Papa had brought home.
②"For the rent（房租）." Mama would count out the big silver pieces.
③"For the groceries." Another group of coins.
④"I'll need a notebook." That would be my brother Nels or me.
⑤Mama would put one or two coins to the side. We would watch with great interest. At last, Papa would ask, "Is that all?" And when Mama nodded, we could relax a little, Mama would look up and smile, "Good, we do not have to go to the Bank." We were so proud of Mama's Bank Account（银行账户）. It gave us such a warm, safe feeling.
⑥When Nels graduated from grammar school, he wanted to go on to high school. "It will cost a little money," he said.
⑦We all gathered around the table. I took down a box and laid it in front of Mama. This was the "Little Bank", which was used for sudden emergencies（紧急事件）. Mama counted out the money in the Little Bank. There was not enough. "We do not want to go to the Bank, right?" she said. We all shook our heads.
⑧"I will work in Dillon's grocery after school," Nels answered.
⑨"I will give up smoking," Dad added.
⑩ "I will look after the children every Friday night," I said.
⑪Mama gave us a bright smile and wrote down a number. "That's quite enough." We all felt good because we didn't have to go down town and draw money out of Mama's Bank Account.
⑫That was twenty years ago.
⑬Last year I sold my first story, I hurried to give the check to Mama. "For you," I said, "to put in your Bank Account."
⑭Mama looked at me, surprisingly. "There is no account," she said. "in all my life, I've never been inside a bank."
⑮And when I didn't- couldn't- answer, Mama said seriously, "It is not good for little ones to be afraid- to not feel safe."
