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.
❓ 根据文章，围绕正式承认人类世为地质时代的争议，主要原因是什么？
A. A. Маркеры воздействия человека, такие как пластик и ядерные изотопы, распределены не глобально.
B. B. Некоторые эксперты сомневаются, достаточно ли значительны изменения, вызванные деятельностью человека, чтобы сравниться с естественными геологическими силами.
C. C. «Великое ускорение» наблюдалось лишь в последние несколько десятилетий, что слишком короткий срок для геологической классификации.
D. D. Существуют разногласия относительно того, следует ли определять антропоцен по уровню углекислого газа или по радиоактивным изотопам.
✅ 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)
