常见错误

1. 1high涉及分数: 2Atmosphere and climate change

   Writing vague, non-specific statements such as 'it damages the environment' or 'causes pollution' instead of explaining precise chemical or biological pathways.

   如何避免: Use specific scientific terminology; explain exact mechanisms, such as 'acid rain lowers soil pH, leaching vital calcium and magnesium ions and releasing toxic aluminum, which damages tree root systems'.
2. 2high涉及分数: 3Foundation - Perspectives, Systems, Sustainability

   Providing a purely one-sided argument in questions containing command words like 'Evaluate', 'Discuss', or 'To what extent'.

   如何避免: Always structure your answer with a balanced perspective, detailing both strengths/advantages and weaknesses/limitations, and conclude with an explicit, supported value-judgment.
3. 3medium涉及分数: 1Ecology

   Conflating bioaccumulation with biomagnification or using the terms interchangeably.

   如何避免: Use bioaccumulation strictly to describe the buildup of a pollutant within a single organism over its lifespan, and biomagnification to describe the increasing concentration of toxins across successive trophic levels.
4. 4medium涉及分数: 1Foundation - Perspectives, Systems, Sustainability

   Omitting measurement units (e.g., 'km' for altitude, 'kg/yr', or '%') when extracting raw values or performing calculations from graphs.

   如何避免: Always check the horizontal and vertical axes of graphs for units, and explicitly state these units alongside your final numerical answers.
5. 5medium涉及分数: 2Foundation - Perspectives, Systems, Sustainability

   Treating positive feedback loops as 'beneficial' or 'good' processes rather than explaining their physical dynamics.

   如何避免: Explain positive feedback strictly as an amplifying cycle that destabilizes a system, driving it further away from its initial equilibrium state.
6. 6high涉及分数: 2Atmosphere and climate change

   Conflating stratospheric ozone depletion (UV absorption/skin cancer risks) with tropospheric photochemical ozone (photochemical smog/respiratory damage).

   如何避免: Distinguish by atmospheric layer: stratospheric ozone is a beneficial shield against harmful UV radiation, while tropospheric ozone is a harmful secondary pollutant formed by NOx and VOCs in sunlight.
7. 7medium涉及分数: 1Natural resources

   Suggesting domestic solid waste recycling as a valid strategy for organic food waste management.

   如何避免: Do not suggest recycling for organic waste; instead, use composting, anaerobic digestion for biogas production, or managed landfilling as appropriate strategies.
8. 8medium涉及分数: 1Foundation - Perspectives, Systems, Sustainability

   Stating only raw values in data-based questions without performing the necessary calculation steps or showing complete workings.

   如何避免: Always show each line of your mathematical calculation (e.g., percentage difference, NIR, or species diversity formulas) to secure working marks even if a minor arithmetic slip occurs.
9. 9high涉及分数: 3Foundation - Perspectives, Systems, Sustainability

   In Paper 2 Section B essays, failing to reference named, localized geographic case studies or specific human societies when explicitly asked.

   如何避免: Prepare and memorize detailed, specific real-world examples (e.g., specific cities, national parks, or agreements) to ground your environmental value systems and waste management evaluations in reality.
