The old man stood there at a loss, his sunken eyes staring at the man seated behind the table. Raising his hand, he wiped the sweat from his forehead and heavily wrinkled face. He didn’t use the traditional kerchief and headband as usual, though he could feel the sweat running down his temple and neck, and he gave no reply to the man seated behind the table who went on asking him, "Why did you go in opening all the doors of the wards looking for your wife Why didn’t you come directly to Enquires" The old man kept silent. Why, though, was the man seated behind the table continuing to open one drawer after another His eyes busy watching him, he said, "I came here the day before yesterday wanting the hospital and looking for the mother of my children." The man seated behind the table muttered irritably, blaming himself for not having ever learned how to ask the right question, how to get a conversation going, and why it was that his question, full of explanations, and sometimes of annoyance, weren’t effective. He puffed at his cigarette as he enquired in exasperation, "What’ s your wife’ s name" The old man at once replied, "Zeinab Mohamed." The man seated behind the table began flipping through the pages of the thick ledger; each time he turned over a page there was a loud noise that was heard by everyone in the waiting room. He went on flipping through the pages of his ledger, pursing his lips listlessly, then nervously, as he kept bringing the ledger close to his face until finally he said, "Your wife came in here the day before yesterday" The old man in relief at once answered, "Yes, sir, when her heart came to a stop." Once again irritated, the man seated behind the table mumbled to himself, "Had her heart stopped she wouldn’t be here, neither would you." With his eyes still on the ledger, he said, "She’ s in Ward 4, but it’ s not permitted for you to enter her ward because there are other women there." Yawning, he called to the nurse leaning against the wall. She came forward, in her hand a paper cup from which she was drinking. Motioning with his head to the man, he said, "Ward Number 4 -Zeinab Mohamed." The nurse walked ahead, without raising her mouth from the cup. The old man asked himself how it was that this woman worked in a hospital that was crammed with men, even though she spoke Arabic. Having arrived at the ward, the nurse left him outside after telling him to wait; then, after a while, she came out and said to him, "There are two women called Zeinab Mohamed. One of them, though, has only one eye. Which one is your wife so that I can call her" The old man was thrown into confusion. One eye How am I to know He tried to recall what his wife Zeinab looked like, with her long gown and black headdress, the veil, and sometimes the black covering enveloping her face and sometimes removed and lying on her neck. He could picture her as she walked and sat, chewing a morsel and then taking it out of her mouth so as to place it in that of her first-born. Her children. One eye. How am 1 to know tie could picture her stretched out on the bed, her eyes closed. The old man was thrown into confusion and found himself saying, "When I call her, she’ll know my voice." The nurse doubted whether he was in fact visiting his wife; however, giving him another glance; she laughed at her suspicions and asked him, "How long have the two of you been married Again, he was confused as he said, ’ Allah knows best — thirty, forty years ...\ Which of the following may least reveal the old man’ s Arabian identity

"I do." To Americans those two words carry great meaning. They can even change your life. Especially if you say them at your own wedding. Making wedding vows is like signing a contract. Now Americans don’ t really think marriage is a business deal. But marriage is serious business, It all begins with engagement. Traditionally, a young man asks the father of his sweetheart for permission to many her. If the father agrees, the man later proposes to her. Often he tries to surprise her by "popping the question" in a romantic way. Sometimes the couple just decides together that the time is fight to get married. The man usually gives his fiancée a diamond ring as a symbol of their engagement. They may be engaged for weeks, months or even years. As the big day approaches, bridal showers and bachelor’ s parties provide many useful gifts. Today many couples also receive counseling during engagement. This prepares them for the challenges of married life. At last it’s time for the wedding. Although most weddings follow long-held traditions, there’ s still room for American individualism. For example, the usual place for a wedding is in a church. But some people get married outdoors in a scenic spot. A few even have the ceremony while sky-diving or riding on horseback! The couple may invite hundreds of people or just a few close friends. They choose their own style of colors, decorations and music during the ceremony. But some things rarely change. The bride usually wears a beautiful, long white wedding dress. She traditionally wears "something old, something new, something borrowed and something blue". The groom wears a formal suit or tuxedo. Several close friends participate in the ceremony as attendants, including the best man and the maid of honor. As the ceremony begins, the groom and his attendants stand with the minister, facing the audience. Music signals the entrance of the bride’ s attendants, followed by the beautiful bride. Nervously, the young couple repeats their vows. Traditionally, they promise to love each other "for better, for worse, for richer, for poorer, in sickness and in health". But sometimes the couple has composed their own vows. They give each other a gold ring to symbolize their marriage commitment. Finally the minister announces the big moment: "I now pronounce you man and wife. You may kiss your bride!" At the wedding reception, the bride and groom greet their guests. Then they cut the wedding cake and feed each other a bite. Guests mingle while enjoying cake, punch and other treats. Later the bride throws her bouquet of flowers to a group of single girls. Tradition says mat the one who catches the bouquet will be the next to many. During the reception, playful friends "decorate" the couple’ s car with tissue paper, tin cans and a "Just Married" sign. When the reception is over, the newlyweds nm to their "decorated" car and speed off. Many couples take a honeymoon, a one-to two-week vacation trip, to celebrate their new marriage. Almost every culture has rituals to signal a change in one’ s life. Marriage is one of the most basic life changes for people of all cultures. So it’s no surprise to find many traditions about getting married ... even in America. Yet each couple follows the traditions in a way that is uniquely their own. In the author’ s opinion ______.

American young couples have no chance to show their individualism in their marriage
B. American young couples don’ t like to follow long-held traditions
C. American young couples are inclined to follow the marriage traditions
D. American young couples marry in their own way
