综合推词：五层证据链与错因反馈

核心动作：综合推断陌生词

陌生词推断应按证据优先级进行：句法词性→构词方向→搭配对象→上下文逻辑→代回校验。任何单一线索都可能误导；五层一致时才有可靠答案。

自拟语境

The new indicator was intended to clarify performance, but its indiscriminate use produced the opposite effect. By treating minor and major errors alike, it obscured the difference the measure was supposed to reveal.

题目：indiscriminate 最接近什么？

A. applied without making relevant distinctions
B. carefully limited to major errors
C. easy for everyone to understand
D. based on secret information

五层推断

句法：形容词修饰 use。构词：in- 否定，discriminate 核心是区分。搭配：use 的方式。逻辑：minor and major alike 导致 obscured difference。A 完整吻合。

B 与 alike 相反；C 把 intended to clarify 当成实际效果，忽略 but/opposite；D 无来源。

错解反馈

若选 C，是把政策目的偷换成结果；若选 B，是前缀或对比关系识别失败。不同错项对应不同修复动作，不能统称“词汇不会”。

正文练习

推断 counterproductive：

Extra reporting was meant to save time, but duplicated forms made the reform counterproductive.

**答案：**产生与预期相反、妨碍目标的效果。counter- 给出反向，but 与 duplicated forms 完成校验。

独立验收

对 indiscriminate 和 counterproductive 分别写出五层推断链，并说明一个看似相关的错义为何被逻辑排除。
