如何用追問讓英文對話更有內容？
英文對話不是一直換新問題。用 Pick → Probe → Open → Build，從對方上一個 answer 抓 detail，追問 clarification、detail、reason、feeling 或 next step，讓聊天自然變得更有內容。
最自然的追問，通常不是想一個全新的問題，而是從對方剛剛的 answer 抓一個 handle，再沿著那條線問下去。
對方說：The interview was harder than I expected, especially the case study at the end. 你下一句卻問：Do you like movies?。Grammar 沒壞，conversation 壞了。追問不是換新題，而是抓住上一個 answer 還沒展開的東西。
Pick → Probe → Open → Build
- Pick：抓一個 noun、event、feeling、decision 或 consequence。
- Probe：選 clarify、detail、reason/feeling、consequence/next。
- Open：想 expand 才給較大的 answer space；只要 verify 就用 closed confirmation。
- Build：下一題繼續從新 answer 裡拿 material。
一句話記住：follow the answer, not your checklist.
為什麼 connected follow-up 比「更多 questions」更重要？
一項刊登於 Journal of Personality and Social Psychology 的研究，在 getting-acquainted conversations 與 speed-dating 資料裡發現，較多 question-asking、尤其 follow-up questions，和較高的 perceived responsiveness 與 liking 有關。這不代表「問越多越討喜」；研究真正提醒我們的是：追問能顯示你有在回應對方剛說的內容。 查看研究。
所以這篇不教 question quota。Conversation 不是 questionnaire with better pronunciation。
Pick：上一個 answer 裡，通常已經藏著下一題
先找一個 handle。比如對方說：
The interview was harder than I expected, especially the case study at the end.
你有兩個很明顯的 handles：harder than I expected 和 the case study at the end。
Original practice example
What made the interview harder than you expected?
直接 recycle 對方的 wording。這種 echo 讓 next question 和上一個 answer 的 connection 一眼可見。
對方用了有 meaning 的 comparison、evaluation 或 surprising detail 時。
聽 partner 一句 answer，先圈出一個 noun 或 phrase，再把它放進下一個 question。
Probe 1：不清楚，就 Clarify；不要假裝你已經懂
如果 handle 本身很 vague，先問 meaning：
Original practice example
What do you mean by “intense” here?
Clarification request 的 job 是讓對方把 vague wording 說清楚，不是要他重講整段。
對方說 weird、intense、complicated 等，而你不知道具體指什麼。
Partner 故意用一個 vague adjective；你只能問那個 word 的 meaning。
另一種是已有 candidate interpretation：When you say “intense,” do you mean the questions were difficult? 這比較接近 confirmation。L2 interaction research 也會把 clarification request 和 confirmation check 分開。查看 interaction study。
Probe 2：有一個具體點，就 Zoom into detail
Original practice example
What was the case study like?
這不是換 topic；它把鏡頭拉近到對方剛提到的 case study。
story、trip、meeting、interview、class、problem 裡出現一個未展開的 detail 時。
聽一個 answer，找最具體的 noun，問一個只關於那個 noun 的 follow-up。
也可以問 sequence：What happened after that?，或 decision process：How did you end up choosing that?
Probe 3/4：想知道 why、feeling、consequence 或 next step
Original practice example
What made you decide to accept it?
這個 question 追的是 decision reason，而不是再問一個 unrelated fact。
對方提到選擇、改變、拒絕、接受、搬家、轉職或其他 decision 時。
Partner 說一個 decision；你在 reason、feeling、consequence、next step 四個方向中只選一個。
- Reason：What made you decide that?
- Feeling：How did you feel about that?
- Consequence：What happened because of that?
- Next：So what are you going to do next?
Closed 還是 open？先看你的 job，不要站隊
Did you like it? 沒問題。如果你只想確認 yes/no，它很有效率。
如果你真正想知道內容，What did you like about it? 給對方更大的 answer space。
- Verify：So you accepted the offer, right?
- Expand：What made you decide to accept it?
Open question 不是道德上更高級。Question shape 要服務 interaction job。
有時只問一句就夠；有時先 respond，再問會更自然
如果內容帶 emotion，你可以先簡短回應，再追問：
That sounds stressful. What happened next?
這裡第一句讓對方知道你有接到 emotional meaning，第二句才 Pull 下一段。但別把每個 follow-up 都做成固定兩句 formula。
Build：下一題，再從新 answer 長出來
Conversation-analysis research 有一個很適合 learner 的提醒：真正的 interactional initiative 往往出現在 speaker 離開原本 script、開始根據前一個 response 調整 follow-up 時。對 novice ESL learner 的 longitudinal analysis 就觀察到 prepared survey list 之外的 post-expansion / follow-up 發展。查看 ESL interaction study。
A: The case study was about launching a product in a new market.
B: What was the hardest part?
A: Deciding how much to spend on advertising.
B: What made that decision difficult?
第二個 follow-up 用了最新 answer 裡的 material。這就是 Build。
追問不是 interrogation：不要讓 conversation 變成問卷
- 不要把 unrelated questions 一題一題堆上去。
- 對方說到 emotional point 時，可以先 respond，再問。
- 有時你也可以 share 一小段自己的 experience，而不是永遠只當 interviewer。
- Private/sensitive detail 不是因為文法問得出來就一定適合問。
- 如果對方開始給很短、關閉式 answers，別硬把同一條線挖到底。
研究裡 follow-up questions 和 responsiveness 的關係，不等於「最多 questions 的人最會聊天」。重點是你有沒有聽到對方剛剛給你的 material。查看研究範圍說明。
追問太 broad？直接把 target 縮小
你問：Why was it difficult? 對方不確定你指哪裡。可以立刻 repair：
I mean, what part was most difficult?
不用重啟整段 conversation。只要把真正想問的 handle 指清楚。
Same Answer, Four Follow-up Jobs
Base answer：The interview was harder than I expected, especially the case study at the end, but I still accepted the offer.
Round A — Clarify
When you say it was harder than you expected, what do you mean?
Random：Do you like working from home?
Round B — Detail
What was the case study like? / What happened when you got to that part?
Round C — Reason / feeling
What made you decide to accept it? / How did you feel after you accepted it?
Round D — Consequence / next
So what are you going to do next?
Closed vs open
Verify: So you accepted it, right?
Expand: What made you decide to accept it?
“Why you chose that?” 為什麼不對？
學習者說法： Why you chose that?
分類：標準 standalone direct question 裡不正確；past simple 通常需要 auxiliary did 放在 subject 前。
聽者會理解：大多能猜到你在問選擇原因。
更自然： Why did you choose that? / What made you choose that?
Context note：embedded clause 可以用 I wonder why you chose that.
一個小練習：One-handle drill
Partner 每次回答後，你先在腦中重複一個 meaningful noun / phrase。下一題一定要用那個 handle。新 answer 出來後，再換新的 handle。
Conversation 是 thread，不是 questionnaire
讓英文對話更有內容，不需要準備一百個「有深度的問題」。更實用的是：follow the answer, not your checklist.
Pick 一個 handle；Probe 它的 meaning、detail、reason、feeling 或 consequence；Open 只有在你真的想聽更多時；然後 Build 下一題從新 answer 出發。
上一個 answer，通常已經把下一題的一半交給你了。
