     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 Merimee, 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 girls 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 a sick neighbor. She became

very ill but began to recover by the time Merimee 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 Mareches'. 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 her family, and in the springtime 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.
