进阶专项：目的、手段与实际结果

唯一新困难：目的与手段

文章中政策目的、实施手段和实际结果是三个层级。干扰项会把“为了”写成“已经实现”，把手段当目标，或把副作用当设计初衷。本课只训练三栏分离。

自拟短文

To reduce missed medical appointments, a clinic began sending reminders two days in advance. The messages included a link for cancellation so that unused slots could be offered to others. Missed visits fell, but last-minute cancellations initially increased, forcing the clinic to adjust its scheduling rules.

题目：Why did the clinic include a cancellation link?

A. To make unused appointment times available again.
B. To increase last-minute cancellations.
C. To replace medical staff with messages.
D. To prove that reminders always work.

三栏拆分

总目的：减少爽约。手段一：提前提醒。手段二：取消链接。取消链接的直接目的：释放空余时段给其他人。结果：爽约减少，但初期临时取消增加。A 正确。

B 是副作用，不是目的；C 无中生有；D 把一次实践夸成普遍证明。

语言标记

to do / so that / in order to 常标目的；resulted in / led to 常标结果；by doing 常标手段。它们可能出现在同一句，但角色不能互换。

迁移练习

能否说“诊所设置链接就是为了增加临时取消”？

**答案：**不能。增加是初期非预期结果，原定目的是回收空余名额。时间副词 initially 还说明结果后来可能被调整。

独立动作验收

把材料填入“总目的—具体手段—直接目的—实际结果—副作用”五格，并解释 B 如何把结果偷换成目的。
