The concept of 'digital twins' has evolved from its industrial origins into a transformative tool for urban planning. A digital twin is a virtual replica of a physical entity, continuously updated with real-time data from sensors. In cities, these models simulate traffic flows, energy consumption, and even emergency responses, allowing planners to test scenarios without disrupting daily life. However, the efficacy of such systems hinges on data quality and integration. Inaccurate or incomplete data can lead to misleading simulations, potentially exacerbating urban problems rather than solving them. Moreover, the reliance on digital twins raises concerns about privacy and the digital divide, as not all communities have equal access to the technologies that feed these models. Despite these challenges, proponents argue that digital twins offer an unprecedented opportunity to make cities more resilient and sustainable, provided that their implementation is guided by robust governance and inclusive participation.
❓ According to the passage, what is a critical limitation of using digital twins in urban planning?
A. A) They are too expensive for most cities to implement.
B. B) Their effectiveness depends on the quality and integration of data.
C. C) They cannot simulate emergency responses accurately.
D. D) They primarily benefit industrial applications, not urban ones.
✅ 正确答案
B) Their effectiveness depends on the quality and integration of data.
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)
