段落大意:
1. 1902年CA新开了家酒店,非常fancy,和以前在southwest的酒店截然不同
2. 19世纪末20世纪初,法院发布water rights条案基于西班牙法(尽管不像),强调西班牙时期的绝对权利,促进了一些monopoly。
3. Hispanic Southwest提倡communal water system,但私人不可未经许可浇灌自己土地。communal water system可以再往前追溯。所以美国学者批评州法院distort Hispanic tradition,但解释为"loss of Hispanic learning"以及没用好Spanish and Mexican water law。
选项分析:
1. D。第一段还没提water rights
2. C。定位到 “American judges asserted that municipal and riparian water rights originating in the Hispanic period were absolute and exclusive.”
3. B。定位到 “This communal water system also restricted the private sector, for riparian owners did not automatically have the right to irrigate their own property, but needed an express or implied grant of water in addition to land. “
4. E。 定位到“ None of these scholars has examined the contemporary background of the key nineteenth- and early twentieth century cases to evaluate the context of these decisions, and none has researched court files to determine the extent to which judges knowingly misused Hispanic law.”
5. B。定位到 “ In some states, this version of Hispanic law persists: in 1975, the California Supreme Court reaffirmed Los Angeles's paramount "pueblo water right" to its local watershed on the basis of stare decisis, despite extensive trial court findings that the right had no historical basis.'”
6. B。定位到“An ornate, turn-of-the-century fantasy of Hispanic architecture, the Inn is completely unlike the unornamented adobe structures that existed in the Southwest before the Americans came.”
7. A。定位到“the legal historians who have attempted to explain this distortion have attributed it to a judicial "loss of Hispanic learning" or to parties failing to present documents on Spanish and Mexican water law to the courts. ”
