Argument47 【loveaw】第7次作业

TOPIC: ARGUMENT47 - Scientists studying historical weather patterns have discovered that in the mid-sixth century, Earth suddenly became significantly cooler. Although few historical records survive from that time, some accounts found both in Asia and Europe mention a dimming of the sun and extremely cold temperatures. Either a huge volcanic eruption or a large meteorite colliding with Earth could have created a large dust cloud throughout Earth's atmosphere that would have been capable of blocking enough sunlight to lower global temperatures significantly. A large meteorite collision, however, would probably create a sudden bright flash of light, and no extant historical records of the time mention such a flash. Some surviving Asian historical records of the time, however, mention a loud boom that would be consistent with a volcanic eruption. Therefore, the cooling was probably caused by a volcanic eruption.

一、没记录不等于陨石撞击没发生
二、Loud boom不排除撞击的可能性
三、可能有其他可能导致气候变冷
The author draws the conclusion that the cooling in the mid-sixth century based on the unsound evidence that some surviving historical records concerning a loud boom which would be consistent of a volcanic eruption eliminate other possible causes, which renders it dubious as it stands.

To begin with, the mere fact that no extant historical records of the time mention a bright flash of light which was created by meteorite collision does not necessarily imply that such meteorite collision has not happened. Perhaps there were relevant records regarding such a meteorite collision, however, those records were lost or have not been discovered so far. Without ruling out such possibility, the author cannot convince me that a meteorite collision did not happen at that time.

Also, the loud boom consisting with a volcanic eruption which was mentioned by some surviving Asian historical records of the time was not necessarily eliminate the possibility that a meteorite collision once occurred. It is entirely possible that the meteorite collision happened in a remote location where people could not hear the loud boom and thus no historiographer recorded such a meteorite collision at that time. Besides, perhaps both the meteorite collision and the volcanic eruption have happened at that time, which did not mutually exclusive. And they contributed to the sudden cooling on the earth at that time together, yet one of the causes, the meteorite collision, was ignored which left no strong evidence and historical records.

Finally, the author fails to take into account other possibilities which were likely to lead to the fact that Earth suddenly became extremely cooler in the mid-sixth century. There is a good chance that due to the periodic change of the Earth's atmosphere that gave rise to lower global temperatures. It is reported and well known that the climate varied periodically in the history of the earth and it often became exceedingly cooler or warmer with the periodic changes of the Earth's atmosphere.

In sum, the author cannot lend strong support to the conclusion that the cooling was likely caused by a volcanic eruption rather than a meteorite collision. To better bolster the conclusion, it would be of great use to provide evidence to rule out other possible causes which were likely to lead to the cooling. Moreover, the author should prove that the lack of historical records on a meteorite collision indicates that such meteorite collision did not occurred at that time.

Finally, the author fails to take into account other possibilities which were likely to lead to the fact that Earth suddenly became extremely cooler in the mid-sixth century.

[这段是想说还有别的原因导致地球变冷的吧,举了这个例子后总结下会更清楚的~~]

In sum, the author cannot lend strong support to the conclusion that the cooling was likely caused by a volcanic eruption rather than a meteorite collision. To better bolster the conclusion, it would be of great use to provide evidence to rule out other possible causes which were likely to lead to the cooling.

PS: 文章有些重要的逻辑错误没有找出来~~
语言方面没有什么问题~~~
还有就是段落相互之前的逻辑性不强~~~
可能批评有点多,其实我也一样,大家一起努力~~

The author draws the conclusion that the cooling in the mid-sixth century based on the unsound evidence that some surviving historical records concerning a loud boom which would be consistent of a volcanic eruption eliminate（liminate的主语是cooling吗？用在这里好像不大合适） other possible causes, which renders it dubious as it stands.

To begin with, the mere fact that no extant historical records of the time mention a bright flash of light which was created by meteorite collision does not necessarily imply that such meteorite collision has not happened. Perhaps there were relevant records regarding such a meteorite collision, however, those records were lost or have not been discovered so far. Without ruling out such possibility, the author cannot convince me that a meteorite collision did not happen at that time.这段的论证不是很有力，论证的话只有一句，提到一种可能，写多点好一些~

Also, the loud boom consisting with a volcanic eruption which was mentioned by some surviving Asian historical records of the time was not necessarily eliminate the possibility that a meteorite collision once occurred. It is entirely possible that the meteorite collision happened in a remote location where people could not hear the loud boom and thus no historiographer recorded such a meteorite collision at that time. Besides, perhaps both the meteorite collision and the volcanic eruption have happened at that time, which did not mutually exclusive. And they contributed to the sudden cooling on the earth at that time together, yet one of the causes, the meteorite collision, was ignored which left no strong evidence and historical records. 个人感觉这段和上一段说得基本是一回事，合并在一起说更有力一些

Finally, the author fails to take into account other possibilities which were likely to lead to the fact that Earth suddenly became extremely cooler in the mid-sixth century. There is a good chance that due to the periodic change of the Earth's atmosphere that（这句都是从句米见到主句，可以把蓝色部分改成it is the periodic change ......that） gave rise to lower global temperatures. It is reported and well known that the climate varied periodically in the history of the earth and it often became exceedingly cooler or warmer with the periodic changes of the Earth's atmosphere.偶对气象不大了解，不明白这个periodic change，但个人感觉这段所提出的periodic change 太笼统，这种change也是应该有原因的，但作者回避了谈这个原因，给人感觉说服力不强

In sum, the author cannot lend strong support to the conclusion that the cooling was likely caused by a volcanic eruption rather than a meteorite collision. To better bolster the conclusion, it would be of great use to provide evidence to rule out other possible causes which were likely to lead to the cooling. Moreover, the author should prove that the lack of historical records on a meteorite collision indicates that such meteorite collision did not occurred at that time.
逻辑不是很清晰，可能我没有明白LZ的意思，认为错误找得不是很中要害
语言很流畅
