    The Marches were a happy family, Poverty, hard work, and even the fact that Father March was away with the Union armies could not down the spirits of Meg, Jo, Beth, Amy, and Marmee, as the March girls called their mother.

    The March sisters tried to be good but had their share of faults. Pretty Meg was often displeased with the schoolchildren she taught; boyish Jo was easy to become angry; golden-haired schoolgirl Amy liked to show up; but Beth, who kept the house, was loving and gentle always.

    The happy days passed and darkness came when a telegram arrived for Mrs. March. “Your husband is very ill,” it said, “come at once.” The girl tried to be brave when their mother left for the front. They waited and prayed. Little Beth got scarlet fever (猩红热) when she was taking care of the sick neighbor. She became very ill but began to recover by the time Marmee was back. When Father came home from the front and at that joyful Christmas dinner they were once more all together.

    Three years later the March girls had grown into young womanhood. Meg became Mrs. Brooke, and after a few family troubles got used to her new state happily. Jo had found pleasure in her literary efforts. Amy had grown into a young lady with a talent for design and an even greater one for society. But Beth had never fully regained her health, and her family watched her with love and anxiety.

    Amy was asked to go and stay in Europe with a relative of the Marches'. Jo went to New York and became successful in her writing and had the satisfaction of seeing her work published there. But at home the bitterest blow was yet to fall Beth had known for some time that she couldn't live much longer to be with the family and in the spring time she died.

    News came from Europe that Amy and Laurie, the grandson of a wealthy neighbor, had planned to be married soon. Now Jo became ever more successful in her writing and got married to Professor Bhaer and soon afterwards founded a school for boys.

    And so the little women had grown up and lived happily with their children, enjoying the harvest of love and goodness that they had devoted all their lives to.

让讲规矩成为新常态

    ①钱穆先生写过一篇《做人的规矩》的文章,说:“诸位将来离开学校踏入社会,谋到了一项职业,做甚么应该像甚么,应该各有各的规矩,各有各的模范。人有人的样子,也便是有规矩了,这是人生最高的艺术。”诚哉斯言!讲规矩确实是人生的最高艺术。

    ②一个人应该讲规矩。一个讲规矩的人,为人处事才会有礼有节,不卑不亢,有君子的气度,有“人的样子”。这样的人,有操守,识分寸,知进退,懂轻重,是一个靠谱的人,一个明白人,一个令人敬重和信任的人。现代社会是一个更加注重契约精神的社会,对个体的规矩意识有着更高的要求,如果不讲规矩,不但有损人品,有亏德行,而且寸步难行,注定一事无成。

    ③一个家庭应该讲规矩。家庭是社会的最基本单元,家庭的规矩串联起来,影响着社会风气,影响着全民的公德素养,影响着国家文化。不难发现,很多民间规矩与社会主义核心价值观的要求是一脉相承的,体现了文明、和谐、诚信、友善等美好理念,我们的家庭不但应该践行规矩,保持对规矩的敬畏和重视,让规矩在家庭教育管理中发挥积极的作用,而且应该承担主要的传承责任,通过言传身教把有价值的规矩一代一代地传下去。

    ④一个政府也应立好规矩,维护规矩。“依法治国”贯穿******的治国理政理念,“法”即规矩。在中国现代化的进程中,先立规矩后办事应是各级政府和管理部门依法行政、科学决策的重要原则,也是社会和谐、有序的基础。自古以来,凡躬订良法者,必定要考虑到它的可操作性和实施效果,故需谨慎研判,反复论证。今天我们的政府在立规矩这件事上,理应有更严谨的态度,更专业的精神,令规矩更有前瞻性、现实性。

    ⑤政府和政府官员须带头守规矩。手握公权力的人坚决按规矩办事,不仅体现了一种品德和修养,更表现了一种政治上的清明与成熟。须知规矩是紧箍咒,更是护身符。朱元璋曾问群臣:“天下何人最快活?”有言位居显赫者最快活,有言富甲一方者最快活……朱元璋均不满意。唯有大臣万钢答道:“天下守法度者最快活。”朱元璋大悦。法度就好比我们的规矩,守规矩者,不越法纪“雷池”,绝无“暗室亏心之忧”,自然能坦坦荡荡,光明磊落。

    ⑥清代画家沈宗骞有一句名言:“以古人之规矩,开自己之生面。”时代飞速发展,社会日新月异,我们不但要懂规矩,守规矩,还要创建与时俱进的新规矩,让讲规矩成为中国的新常态。
