39、2，分数：80.00)BPassage One/BIt is not often realized that women held a high place in southern European societies in the 10th and 11th centuries. As a wife, the woman was protected by the setting up of a dowry or decimum. Admittedly, the purpose of this was to protect her against the risk of desertion,

40、but in reality its function in the social and family life of the time was much more important. The decimum was the wifes right to receive a tenth of all her husbands property. The wife had the right to withhold consent, in all transactions the husband would make. And more than just a right: the docu

41、ments show that she enjoyed a real power of decision, equal to that of her husband. In no case do the documents indicate any degree of difference in the legal status of husband and wife.The wife shared in the management of her husbands personal property, but the opposite was not al- ways true. Women

42、 seemed perfectly prepared to defend their own inheritance against husbands who tried to exceed their rights, and on occasion they showed a fine fighting spirit. A case in point is that of Maria Vivas, a Catalan woman of Barcelona. Having agreed with her husband Miro to sell a field she had inherite

43、d for the needs of the household, she insisted on compensation. None being offered, she succeeded in dragging her husband to the scribe to have a contract duly drawn up assigning her a piece of land from Miros personal inheritance. The unfortunate husband was obliged to agree, as the contract says,

44、for the sake of peace.“ Either through the dowry or through being hot-tempered, the Catalan wife knew how to win herself, within the context of the family, a powerful economic position.（分数：40.00）(1).A decimum was _.（分数：8.00）A.the wifes inheritance from her fatherB.a gift of money to the new husband

45、C.a written contractD.the wifes right of having 10 percent of her husbands property(2).In the society described in the passage, the legal standing of the wife in marriage was _.（分数：8.00）A.higher than that of her husbandB.lower than that of her husbandC.the same as that of her husbandD.higher than th
