9-17 综合 第一个点第一次听的时候听错了.... 有点沾边但是逻辑意思不对..... 所以.... 哎
In the reading passage, there are causes ofthe formation of Little Ice Age. However, the professor refutes that thosereasons are out of date, and there are new information provided.
First, the reading says it is thedisruption of ocean currents that caused the cooling effect, and Little Ice Ageoccurred. However, the professor argues that the disruption merely exerted cooling effect on the North America, and the reason offered cannot explain the same phenomenon in the south area such as New Zealand(真的不会拼) and South Africa, whichcould also be affected by the Little Ice Age. [第二遍应该听对了吧]
Second, the reading implies that volcaniceruption resulted in the Little Ice age, but the professor totally disagrees with this reason. He says the dust can cause striking visual effects such as the colorful sunlight and snow appeared as brown or grey color instead of whitecolor. However, there were no routinely report for the effect. So, the effectof volcanic eruption did not produce such a strong effect that could lower thetemperature.
Last, the reading believes the tremendous decreases in human population would lead to the cooling effect and result in Little Ice Age. However, the professor argues that people would quickly grow back to the normal level. Also, the forest would be cut in accordance with theincreasing population which needs agriculture. As a result, there would existenough carbon dioxide to keep the Earth warm.
