本课只做一件事：用 5 道题检验「综合复习：D1 计算专项」，并把错的那几道归到具体原因上。
Test Review: D1 Calculations with five items and trace every miss to a specific cause.
本课不涉及：不出新知识点——只检验前四课学过的内容。
Not covered here: No new material — only what lessons 1 to 4 covered.
本课目标 | Learning objectives
- 5 题至少答对 4 题，并说清每题依据
- 把错题归为「词不懂 / 问句读错 / 依据不足」三类之一
- 说出本块学到的三条可迁移结论

五题复盘 | Five-question recap
选出答案并提交，查看解析与依据。/ Pick an answer, submit, and read the rationale.
1. 坠落净空的四个加数是？
The four clearance addends?
2. Ds 的公式与下限是？
Ds formula and floor?
3. OSHA 口径 105 dBA 允许多久？
OSHA allows how long at 105 dBA?
4. TRIR 的分母口径是？
The TRIR denominator is?
5. 计算题每题限时建议？
The recommended per-item cap is?
错因归类 | Sort your misses
- 净空只算绳+缓冲 → 漏 D 环高度与余量，恰好掉进错误选项Clearance counting only the rope plus decelerator → omitting D-ring height and margin lands you exactly in the wrong option
- dBA 当线性 → 「响一倍=+6dB」是经典陷阱Treating dBA as linear → "twice as loud = +6 dB" is a classic trap
- TRIR 分母用人数 → 公式只认 200,000 工时口径Using headcount as the TRIR denominator → the formula only recognizes the 200,000-hours basis
接下来学什么：下一块（Day 302–306）继续综合复习：D2 情景专项——角色、工具、指标，三步定答案。
Next block (Days 302–306) continues review with D2 scenarios — role, tool, metric, then answer.
