研究人员称大禹治水可能是真实事件

In 2016， a team of scientists led by Dr. Wu Qinglong of Nanjing Normal University found scientific evidence of a massive flood in China. They dated the flood back to 1920 BC on China’s Yellow River in the Jishi Gorge. The location and scale of this flood lead experts to believe that the ancient legend of the Great Flood of China may have been， in part， a real event in history.

According to one version of the legend， China’s great flood happened on the upper banks of the Yellow River. The first person to attempt to control the flood was a man named Gun. However， Gun failed and was killed by the fire god at Yushan Mountain. From his dead body， a dragon was born three years later. The dragon went up to heaven and was born again as Gun’s son， Yu the Great. Yu controlled the floods with the help of a mighty dragon and a strong black turtle. Yu was so successful that he received a heavenly order to become the ruler and founder of the first dynasty of China， the Xia Dynasty.

The flood happened in the upper valley of the Yellow River， and this is consistent with the legend. The scientists also found the remains of dams of the right age and sedimentation deposits（沉积物） characteristic of those associated with a monstrous flood.

In 2000 scientists also discovered an ancient civilization， called Lajia. A landslide（塌方） had destroyed the village as a result of a powerful earthquake. Scientists discovered that the bodies of the people killed in the earthquake had the same age as artifacts（文物） linked to the flood. The earthquake site had sedimentation in it that indicated floodwaters had reached it. In fact， the researchers found that the earthquake and flood happened during the same year.

Putting together the pieces of the puzzle， scientists determined that the earthquake caused the huge flood by triggering a landslide that dammed up the river in the Jishi Gorge. The water built up behind the rocky dam for 6 to 9 months until eventually， the dam broke. The waters flooded the upper valley， destroying everything in its path.

1. C。解析：细节理解题。根据材料第一段中的“They dated the flood back to 1920 BC on China’s Yellow River in the Jishi Gorge. The location and scale of this flood lead experts to believe that the ancient legend of the Great Flood of China may have been， in part， a real event in history.”，我们可知中国古代的大洪水的可能发生地点就是Jishi Gorge。故选C。

2. B。解析：推理判断题。根据材料第二段中的“However， Gun failed and was killed by the fire god at Yushan Mountain.”和“Yu controlled the floods with the help of a mighty dragon and a strong black turtle.”，我们可知Gun和Yu的治水任务是既危险又困难的。故选B。

3. A。解析：细节理解题。根据材料第四段中的“A landslide had destroyed the village as a result of a powerful earthquake. Scientists discovered that the bodies of the people killed in the earthquake had the same age as artifacts linked to the flood.”，我们可知有着Lajia Civilization的村庄被地震导致的塌方所摧毁，而科学家发现地震遇难者的尸体和与大洪水有关的文物年代相同。故选A。

4. A。解析：细节理解题。根据材料第五段中的“Putting together the pieces of the puzzle， scientists determined that the earthquake caused the huge flood by triggering a landslide that dammed up the river in the Jishi Gorge.”，我们可知整个事件的顺序是：地震导致塌方，塌方导致河流堰塞，最后引发洪水。故选A。
