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 impacts, the Anthropocene is characterized by markers like plastic pollution, radioactive fallout from nuclear tests, and elevated carbon dioxide levels. However, the formal recognition of this epoch remains contentious, as some scholars argue that human influence, while pervasive, has not yet produced a distinct stratigraphic signal comparable to that of earlier transitions. Others contend that the term itself is useful beyond geology, serving as a cultural and political catalyst for discussions on sustainability and planetary stewardship. This debate highlights the intersection of scientific classification and societal values, raising questions about how we define boundaries in both time and responsibility.
❓ Согласно тексту, почему формальное признание антропоцена как геологической эпохи вызывает споры?
A. A) Поскольку влияние человека ещё недостаточно широко распространено, чтобы воздействовать на глобальные экосистемы.
B. B) Потому что некоторые учёные считают, что ему не хватает чёткого стратиграфического маркера, сопоставимого с прошлыми эпохами.
C. C) Потому что этот термин используется только в культурном и политическом контексте, а не в геологии.
D. D) Потому что вулканическая активность и удары астероидов по-прежнему являются основными силами, формирующими Землю.
✅ 正确答案
B) Because some scientists believe it lacks a clear stratigraphic marker comparable to past epochs.
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)
Manage time: about 20 minutes per passage; skip difficult questions first
