    The right name is important in the business world. All you have to do is to think of the names for some of the products you buy every day and you'll agree that the name and the product are connected in everyone's mind.

    In many countries, successful trade or brand(商标)names are protected by law so that other companies cannot make the same product by copying. Businesses register(注册)a company or a product name with the government. In fact, more than 1,000 product and company names are registered every hour. Many companies spend a lot of money to find the right name for their products. A good example of this is in the car industry. Some successful names for cars have powerful associations(联系).The Ford Mustang and the Jaguar are only two examples of choosing the names of animals that are fast and strong.

    When a U.S. company decides to sell its product in another country, it has to make sure that the product name translates properly. When Coca-Cola introduced its soft drink to China it looked for the right name. It wanted a name that would do two things. One was to present its image in Chinese and the second was to be close to its first brand name-Coke. It took some efforts before finding the right word-which sounds similar and translates as "happiness in the mouth".  Asian company names are not new to the United States. The brand names of Samsung and Sony have been successful. Finding the right brand name is a big business. Asian companies that sell to foreign markets pay to find a name that will connect with its customers. There are even naming companies that offer help in inventing product names. These companies can charge(要价)up to $ 100,000 a word for their good names. But it's worth it. Successful companies know how important the right brand names are for their development.

    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 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 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 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.
