请为我挑选一篇与考研英语一选材特征相符的外刊文章(来源限 The Economist / The Guardian / Scientific American / Nature / The New York Times / The Atlantic 等历年真题来源刊物),主题属于 {{科技 / 社会 / 法律 / 经济 / 教育 / 文化}}。
分类:
1. 指代类(this / that / these / such / the former / the latter)
2. 逻辑类(however / therefore / moreover / nevertheless / conversely)
3. 例证类(for example / for instance / take ... as an example)
4. 因果类(as a result / consequently / thus)
5. 总结类(in short / overall / in conclusion)
6. 时间类(earlier / previously / meanwhile / subsequently)
7. 比较类(similarly / in the same way / by contrast)
8. 结构类(first / second / finally / on the one hand)
判定标准:
1. 是否为高频套句(如 "With the rapid development of society..." "As far as I am concerned..." "Every coin has two sides")
2. 是否为空泛表述(无具体信息、可套任何话题)
3. 是否句式单一(连续 3 句以上同一句型)
