本课目标

学完本课，你能够：

• 用Suppose … / What if …?邀请对方探索方案；
• 用第二条件句讨论当前尚属假设的做法和可能结果；
• 区分“值得测试”“已经决定”和“将会发生”；
• 说出一个方案成立所需的条件及可能副作用；
• 把大范围建议缩成可观察的小测试。

本课边界

本课讨论的双阶段反馈方案仍是假设。说If we used both forms, …不表示团队已经批准使用两种表格，也不表示公众活动已经确定。测试继续使用空白展板和通用方向文字，不收集姓名、联系方式或候选材料意见。

场景词汇

• two-stage method 双阶段方法
• exit question 离场问题
• follow-up form 后续表单
• anonymous symbol 匿名符号
• duplicate response 重复反馈
• analysis time 分析时间
• prototype 原型
• condition 成立条件

Exploring a combination before approving it

After Lesson 61, paper is the provisional default for the internal route rehearsal. Daniel wonders whether a small optional digital follow-up could add useful detail without removing the device-free route.

Part A — Making the hypothetical concrete

Daniel: Suppose we tried a two-stage method: a three-question paper checklist at the exit and an optional QR follow-up later.

Aisha: What would the second stage add that the paper form doesn’t already collect?

Daniel: If people had another twenty-four hours, they might remember a detail after leaving the building.

Grace: That might work if the QR form asked only two reflection questions. A second full checklist would create duplicate work.

Aisha: What if someone used only the paper form?

Daniel: Their response would still be complete. The QR stage would be optional, not a missing half of the process.

Grace: If we used one anonymous symbol on both forms, we could compare immediate and later comments without collecting names.

Aisha: One possible consequence is that people could think the symbol identifies them.

Daniel: Then we would need a short privacy note explaining that the three symbols are random and contain no personal information.

Grace: Or we could avoid linking the forms at all. We would lose the comparison, but the process would be simpler.

Part B — Designing a limited test

Aisha: I’d prefer the simpler version. If we added tracking before we knew we needed it, we would create an unnecessary privacy concern.

Daniel: Fair point. Suppose the paper form collected the route location, and the optional QR form collected only later reflections.

Grace: In that case, we wouldn’t try to match one person’s two responses. We would compare the kinds of detail each method produces.

Aisha: The downside is extra analysis time. We would have two small sets of comments instead of one.

Daniel: We could test it by making one paper prototype and one two-question QR prototype, then asking three staff members to use both.

Grace: If the same testers used both, we could inspect the response types, but we couldn’t measure natural format preference.

Aisha: Exactly. The test would answer “What detail does each form invite?” not “Which method would visitors choose?”

Daniel: That’s a useful limit. I’ll draft the two prototypes, but I won’t publish or distribute them.

Grace: If the drafts stay anonymous and use only generic route content, I’ll review the questions tomorrow.

Aisha: Good. We’re agreeing to examine a prototype, not to adopt a two-stage public system.

Hypothesis card

Proposed feature	Possible benefit	Possible consequence	Test limit
3-question paper exit form	immediate location mark; no device	later data entry	generic route only
optional 2-question QR follow-up	later reflection	two data sets; phone needed	not a required stage
no cross-form tracking	simpler privacy message	cannot pair responses	compare response types only

Check the story

1. What does Daniel’s two-stage idea contain?
2. Can a paper-only response be complete?
3. Why does Aisha question anonymous symbols?
4. What simplification does the group choose?
5. What can the proposed test show?
6. What has the group not approved?

三种状态不能混写

Status	Example	Meaning
hypothesis	If we used two forms, we would get two sets of comments.	探索可能后果
limited test	Daniel will draft two unpublished prototypes.	已同意的小步骤
adoption	We will use both forms at the public event.	尚未决定，不能写成事实

第二条件句不是“不可能”

第二条件句常表示与当前事实有距离的假设：

If we used both forms, we would need more analysis time.

这个方案可能发生，但说话者暂时把它放在“探索而非承诺”的框架里。

好的测试问题有限

本课原型可以回答：

• 两种问题分别引出什么类型的细节？
• 表格说明是否清楚？

不能回答：

• 所有访客更喜欢什么？
• 公众活动应该永久使用哪种系统？
• 三名员工的行为是否代表不同访客群体？

本课负荷说明

本课主动掌握6个新词块。第61课的比较语言和第60课的限制／确认语言在主对话与练习中继续复现。

1. Suppose we tried …

邀请对方共同探索一个尚未批准的方案。

Suppose we tried a shorter form first.

2. What if we …?

提出另一种可能或压力测试。

What if we removed the tracking symbol?

3. If we did that, we would …

说明假设行动可能带来的结果。

If we did that, we would lose the ability to pair responses.

4. That might work if …

有限度地接受方案，同时指出成立条件。

That might work if the second form stayed optional.

5. One possible consequence is …

提前指出副作用或间接结果，不把它说成必然。

One possible consequence is extra analysis time.

6. We could test it by …

把抽象争论缩成具体、低风险的观察步骤。

We could test it by comparing two unpublished prototypes.

Don’t Say It That Way

容易说出的句子	问题	更准确的表达
Suppose we will use both.	suppose后的假设框架不自然	Suppose we used both.
If we would add QR, …	标准第二条件句的if从句不用would	If we added QR, …
We tested it, so it is approved.	测试不等于采用	The test supports another review; it does not approve public use.
Three staff would prove what visitors prefer.	样本和任务不支持	Three staff could show whether the prototype questions are clear.

---

1. 基本结构

If + 一般过去时, would + 动词原形

If we used two forms, we would need more analysis time.

这里的一般过去形式不表示过去时间；它表示与当前决定保持假设距离。

2. could / might也可进入结果部分

If we used paper first, everyone could respond without a phone.
If people had more time, they might remember another detail.

• would：预期结果；
• could：能力或机会；
• might：可能结果。

3. be在正式标准形式中可用were

If the form were shorter, more people might finish it.

日常口语中was也能听到，但本书主动练习采用were。

4. 与第一条件句区分

已确认的现实下一步：

If Grace approves the draft tomorrow, Daniel will print three test copies.

尚未决定的方案：

If they used both forms publicly, they would need a clearer privacy notice.

5. 不把假设写成承诺

We could test the prototype.
We will adopt the system.

前一句是可能的小测试，后一句是已决定采用；目前材料只支持前一句。

快速练习

用正确形式完成：

1. Suppose we ______ (try) a two-question follow-up.
2. If we ______ (use) both forms, we ______ (have) two data sets.
3. If the second stage were optional, people ______ (can) stop after paper.
4. One possible consequence ______ (be) extra analysis time.
5. If Grace ______ (approve) the real draft tomorrow, Daniel will print three test copies.
6. That might work if the privacy note ______ (be) clear.

---

Suppose后轻停顿，不要像宣布决定：

SUPPOSE / we tried a two-stage method. ↗

把条件和结果分成两个意群：

If we used BOTH FORMS, / we would need more ANALYSIS TIME.

提出风险时，possible不重读成必然：

One possible CONSEQUENCE is / duplicate work.

有限接受先升后降：

That MIGHT work / if the second stage stayed OPTIONAL. ↘

影子跟读

Suppose we tried a two-stage method.
What if someone used only the paper form?
One possible consequence is extra analysis time.
We could test it by comparing two prototypes.

---

A. 理解检查

判断正误：

1. The QR follow-up would be required.
2. The group decides to link responses to names.
3. Not linking the forms simplifies the privacy question.
4. The prototype test can measure natural visitor preference.
5. Daniel may draft prototypes without publishing them.
6. The group has approved a permanent public system.

B. 第一还是第二条件句？

选择合适形式：

1. If the printer confirms today, we (will print / would print) three copies tomorrow.
2. If we used eight questions, the form (will take / would take) too long.
3. If Grace approves the final test wording, Daniel (will add / would add) it to the prototype.
4. If the QR stage were optional, paper-only responses (will remain / would remain) complete.
5. If the current connection fails during tomorrow’s test, we (will record / would record) the failure.
6. If we tracked every response, we (will create / would create) a new privacy concern.

C. 补全后果链

为每个假设写一个收益、一个风险和一个测试：

1. Suppose we shortened the paper form to one question.
2. What if the QR form stayed open for a week?
3. Suppose the debrief happened in a group.
4. What if testers could choose any method?

必须使用would / could / might各至少一次。

D. Lesson 61近距离检索

比较“一个完整长表”和“两个短阶段”，写六句，依次使用：

• Which one makes more sense for …?
• Compared with …, …
• The main advantage is …
• The downside is …
• Because … / Therefore …
• On balance, …

E. Lesson 60第二次检索

一个原型工具无法匿名保存，另一个只能在电脑使用。用CH351—CH356重新规划测试：原方案失效、首要优先级、排除理由、当前最佳选择、需预留时间和最终确认点。

F. 中译英调解

同事A说：“既然双阶段可能更好，我们就直接对公众上线。”同事B说：“任何数字表单都不应该使用。”用100—130词调解：

1. 把“可能”与“批准”分开；
2. 承认两边各一项合理考虑；
3. 提出一个不公开的有限测试；
4. 说明测试能和不能回答什么；
5. 设置重新讨论的证据条件。

G. 2分钟假设探索录音

选择一个尚未决定的生活方案。至少提出：

• two Suppose / What if questions;
• two second conditionals;
• one possible consequence;
• one condition for success;
• one limited test.

结尾必须明确当前尚未决定什么。

H. 实用写作：原型测试说明

写110—150词，包含：

• hypothesis;
• prototype scope;
• participants or materials;
• information not collected;
• one expected benefit and one possible consequence;
• evidence the test can produce;
• decision the test cannot make.

I. 中译英情境表达

1. 假如我们试试双阶段方法呢？
2. 如果有人只使用纸质表怎么办？
3. 如果这样做，我们会得到两组反馈。
4. 如果第二阶段保持可选，这也许可行。
5. 一个可能的后果是分析时间增加。
6. 我们可以通过比较两个未发布的原型来测试它。

建立“假设—证据”卡

写下你正在考虑的一项变化，然后完成：

• If I did this, I would …
• It might work if …
• One possible consequence is …
• I could test it by …
• The test would show …
• The test would not show …

检查隐形承诺

圈出will / definitely / we are going to。如果还没有真实决定，把它改成would / could / might；如果确有已确认下一步，保留will并写清负责人和时间。

两天后的复测

只看：

SUPPOSE → IF / WOULD → CONDITION → CONSEQUENCE → LIMITED TEST → NOT YET DECIDED

用全新方案完成两分钟无稿探索。
