【简答题】
The Bedouin people think most highly of people who show loyalty. To them loyalty does not mean that one is devoted to a country, a place, or a leader. Loyalty means being faithful to one’s family and tribe. The Bedouin take pride in their ancestors. They do not admire a hero from an ordinary or poor family as much as one who comes from an honored family. They particularly respect those who have inherited a good name and then have passed it on to their children. A man’s position among the black-tent people depends upon his ancestors, relatives, and fellow tribesmen. If they are honored, he is also honored. If they are disgraced, he too is disgraced. Therefore one carefully guards the honor of his family, his lineage (直系,家族), and his tribe. A man can protect his family’s honor by being brave and generous and by giving protection to those who ask for it. He also guards it by carefully watching the women of his family. A Bedouin woman can not bring honor to her family, but she can bring disgrace. Even if a woman only looks as if she has done wrong, she may be killed. The honor of her family depends upon her virtue.
