问题     Since the 1970s, archaeological sites in China’s Yangtze River region have yielded evidence of sophisticated rice-farming societies that predate signs of rice cultivation elsewhere in East Asia by a thousand years. Before this evidence was discovered, it had generally been assumed that rice farming began farther to the south. This scenario was based both on the geographic range of wild or free-living rice, which was not thought to extend as far north as the Yangtze, and on archaeological records of very early domestic rice from Southeast Asia and India (now known to be not so old as first reported). Proponents of the southern-origin theory point out that early rice-farming societies along the Yangtze were already highly developed and that evidence for the first stage of rice cultivation is missing. They argue that the first hunter-gatherers to develop rice agriculture must have done so in this southern zone, within the apparent present-day geographic range of wild rice. Yet while most strands of wild rice reported in a 1984 survey were concentrated to the south of the Yangtze drainage, two northern outlier populations were also discovered in provinces along the middle and lower Yangtze, evidence that the Yangtze wetlands may fall within both the present-day and the historical geographic ranges of rice’s wild ancestor. [br] Which of the following can be inferred from the passage about the “southern-origin theory”?
选项 A、The theory is based on an unconventional understanding of how hunter-gatherers first developed rice agriculture.
B、The theory fails to take into account the apparent fact that evidence for the first stage of rice cultivation in the north is missing.
C、The theory was developed primarily in response to a 1984 survey of wild rice’s geographic range.
D、Reassessment of the dates of some archaeological evidence has undermined support for the theory.
E、Evidence of sophisticated rice-farming societies in the Yangtze region provides support for the theory.
答案 D
解析 D选项定位到第三句括号里的内容。以前人们认为东南亚的水稻种植发生在非常早期，因此这一证据可以用来支持南方起源论。但是括号部分说，东南亚的证据不如一开始认为得那么久远，也就是说最近的证据表明东南亚的水稻种植的时间其实并不久远，因此东南亚的证据便无法再用来支持南方起源论了。A项：南方起源论在文中是老观点，老观点不能基于“非传统”的内容，这在时间上是矛盾的，因为老观点被提出的时候，还没有出现新观点。老观点何谈基于新观点?B项：根据第四句，南方起源论尤其考虑到了这一点。选项C和选项A犯了一样的错误，1984在文中对应新观点，老观点被提出时，还没有新观点。E项对应的是第一句，而第一句的sophisticated rice-farming societies则是支持长江是水稻种植的起源地的，而非支持南方。
