The concept of the 'Anthropocene' has gained traction among geologists and environmental scientists as a proposed new geological epoch defined by significant human impact on Earth's geology and ecosystems. Unlike previous epochs, which were shaped by natural forces such as volcanic activity or asteroid collisions, the Anthropocene is characterized by markers like radioactive isotopes from nuclear tests, plastic pollution, and elevated carbon dioxide levels. However, the formal recognition of this epoch remains contentious. Some scholars argue that human influence, while profound, is not yet comparable to the long-term, planet-scale changes that define earlier geological boundaries. Others counter that the rapid acceleration of anthropogenic effects since the mid-20th century, termed the 'Great Acceleration,' justifies a distinct classification. This debate highlights the tension between geological precision and the need to acknowledge humanity's unprecedented role in shaping the planet's future.
❓ 지문에 따르면, 인류세를 지질학적 시대로 공식 인정하는 것에 대한 논란의 주요 이유는 무엇인가?
A. A. 인간의 영향 지표, 예를 들어 플라스틱과 핵 동위원소는 전 세계적으로 고르게 분포되어 있지 않다.
B. B. 일부 전문가들은 인간이 유발한 변화가 자연적 지질학적 힘에 견줄 만큼 충분히 중요한지 의문을 제기한다.
C. C. '대가속(Great Acceleration)'은 최근 수십 년 동안에만 관찰되었으며, 이는 지질학적 분류를 하기에는 너무 짧은 기간이다.
D. D. 인류세를 이산화탄소 농도로 정의해야 하는지, 방사성 동위원소로 정의해야 하는지에 대해 의견이 분분하다.
✅ 正确答案
B. Some experts question whether human-induced changes are significant enough to match natural geological forces.
IELTS Reading Tips
Skim the questions first, underline keywords, then locate in the passage
Watch for paraphrasing; correct answers are often reworded
Be wary of absolute statements (all, always, never) — usually wrong
Pay attention to content after transition words (however, but, yet)
