2021—2022 比较题：维度、条件与适用场景

能力目标：处理比较与对照

比较题最容易错在维度错位。看到 A better than B，必须问“在哪个指标、什么条件、哪个时间范围内更好”。选项若更换比较维度，即使方向相同也不成立。

自拟短文

Paper forms require manual entry but remain usable during network failures. Digital forms reduce repeated typing and make records easier to search, though they depend on reliable devices. In a six-month trial, digital forms saved staff time in large clinics, while small mobile units preferred paper because connectivity varied throughout the day.

题目：What does the trial suggest?

A. Digital forms are superior in every setting.
B. Paper forms always produce more accurate records.
C. The practical advantage of each form depends on working conditions.
D. Small units lack employees able to use devices.

建立比较表

纸质：人工录入、断网可用；数字：少重复输入、易检索、依赖设备。试验又加入场景：大型诊所节省时间，小型流动点受连接影响。作者不是评选永久赢家，而是指出不同条件改变优势，因此 C 正确。

A 删除场景条件并扩大为 every；B 把可用性偷换成准确性；D 为偏好纸质添加人员能力原因。

同维度比较

usable during failures 与 depend on reliable devices 都在比较基础设施韧性；manual entry 与 reduce repeated typing 比较工作量。不能把一个维度的证据拿去证明另一维度。

独立练习

能否由材料推出“大型诊所的数字记录更准确”？

**答案：**不能。材料只说明节省 staff time，没有给出准确率数据。把效率优势迁移到准确性属于比较维度偷换。

独立动作验收

画出“工具×维度×场景”三列表，并用它解释 A、B、D 分别删掉或添加了什么。
