ARGUMENT207
It is known that in recent years, industrial pollution has caused the Earth's ozone layer to thin, allowing an increase in the amount of ultraviolet radiation that reaches the Earth's surface. At the same time, scientists have discovered, the population of a species of salamander that lays its eggs in mountain lakes has declined. Since ultraviolet radiation is known to be damaging to delicate tissues and since salamander eggs have no protective shells, it must be the case that the increase in ultraviolet radiation has damaged many salamander eggs and prevented them from hatching. This process will no doubt cause population declines in other species, just as it has in the salamander species.

Background:
1.industrial pollution has caused the Earth's ozone layer to thin；
2. the population of a species of salamander that lays its eggs in mountain lakes has declined；
Supports:
1. ultraviolet radiation is known to be damaging to delicate tissues；
2. salamander eggs have no protective shells；
Conclusion:
1. the increase in ultraviolet radiation has damaged many salamander eggs and prevented them from hatching；
2. will no doubt cause population declines in other species, just as it has in the salamander species；
作者逻辑结构：
B1+S1+S2à1àC1à2àB2à3àC2


故对1，2，3处展开攻击即可:
1: 承认S1紫外线破坏组织，但S2中说没有壳，但也有可能有其他的保护层，再者未说明什么蜥蜴，有些总类的蜥蜴可能卵产于地下，卵由上面的覆盖物保护
2: 对于C1àB1，产卵数量下:
(1).即使是紫外线破坏，可能是紫外线影响该种蜥蜴的生活习性从而影响其产卵而非直接影响其卵本身，使得其后代数量减少
(2).即使紫外线能破坏很多卵，但蜥蜴产卵总量远远大于被破坏量，所以这种影响并不大，反而可能是其生活环境的改变，天敌的增加，人类的猎杀影响这种蜥蜴数量
3: 即使蜥蜴的减少是因为紫外线伤害其卵，但对于其他卵生但有保护壳的物种，且有些物种的卵产于地下紫外线不能到达，所以就不一定能够伤害。即使紫外线对卵生物种有影响，但对于其他哺乳的物种就不一定会影响。

正文没有时间写了，抱歉，期末复习真的很紧张，很多东西要做！
有时间会补上的。
