The concept of 'digital twin' has gained significant traction in industrial engineering, referring to a virtual replica of a physical system that is continuously updated with real-time data. This technology enables predictive maintenance by simulating potential failures before they occur, thereby reducing downtime and operational costs. However, the efficacy of digital twins hinges on the quality and volume of data collected, as well as the sophistication of the algorithms used to process it. Critics argue that over-reliance on such models may lead to complacency, particularly when the physical system deviates from its digital counterpart due to unforeseen environmental factors. Nevertheless, proponents maintain that with robust validation protocols, digital twins offer an unprecedented level of insight into complex machinery, facilitating more informed decision-making and optimization of performance.
❓ What is a primary concern regarding the use of digital twins mentioned in the passage?
A. A. They are too expensive to implement in most industries.
B. B. They may not account for unexpected changes in the physical system.
C. C. They require too much human intervention to be effective.
D. D. They are only useful for new, not existing, machinery.
✅ 正确答案
B. They may not account for unexpected changes in the physical system.
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
