第 6 課 · Follow-ups 追問延伸：Keeping the ball rolling

Two conversations. Same weekend. Watch which one dies.

Version A

A: So what'd you get up to this weekend?
B: I went hiking, actually.
A: Oh, nice.
B: …Yeah.
(silence. someone checks their phone.)

Version B

A: So what'd you get up to this weekend?
B: I went hiking, actually.
A: Oh nice — whereabouts?↗
B: Up Yangmingshan. We did the Qixing peak trail.
A: Ohh, the whole thing?↗ How long'd that take you?
B: About four hours. I was wrecked afterwards.
A: Ha, I bet.

Same opening line. In Version A, B's answer is correct — nothing wrong with it. But the ball hits the floor and nobody picks it up. In Version B, A keeps throwing the ball back, and suddenly there's a conversation.

That "throwing the ball back" move is this entire lesson. It's called a follow-up（追問延伸）: 順著對方的話再問一句，讓對話滾下去。

💡 記號沿用第 1 課：粗體 = stress 重音（句中被強調的字），↗ / ↘ = intonation 語調（尾音上揚 / 下降）。這一課的 ↗ 特別重要，等下你就知道為什麼。

前面第 3–5 課，你學的都是怎麼接住對方丟來的球：

• 第 3 課 backchannel 附和回應（mm-hmm / right / gotcha）：邊聽邊發的小訊號，「我在聽，繼續」。
• 第 4 課 reaction 反應語（No way! / That's awful / Oh nice）：表達驚訝、同理、興奮。
• 第 5 課 filler 填充詞（um / well / you know / I mean）：邊想邊講，幫自己爭取半秒。

接住球是必要的。但只接不丟，對話還是會停。這一課教的就是接住之後那一下——把球丟回去。

The ball keeps dropping（對話為什麼會冷掉）

新手最大的誤會，是以為對話冷掉是因為「我英文講錯了」。通常不是。看看這些——每一句都文法全對，每一段都死得透透的：

A: I just got back from Tokyo.
B: That's cool.
(the end.)

A: I'm learning to play the guitar.
B: Oh, good for you.
(the end.)

A: My dog had surgery last week.
B: I see.
(the end.)

沒有一句「錯」。問題是每一句都是句點型回應——接住，然後就沒了。球停在 B 手上，直到掉地上。

The fix is one move. After you catch the ball, throw it back — usually as a small question built out of what they just said:

A: I just got back from Tokyo.
B: Oh nice — how long were you there?↗
A: Just five days. Way too short.
B: Five days?↗ What'd you get to see?
A: Mostly ate, honestly…

Same B, same English level. The only difference is B keeps lobbing the ball back over the net. That loop is the whole game:

flowchart LR
    A["對方說了一句"] --> B["你接住：backchannel / reaction"]
    B --> C["你丟回去：follow-up 追問延伸"]
    C --> D["對方又說更多"]
    D -->|"the ball keeps rolling"| A

There are two easy ways to throw the ball back. We'll take them one at a time. The first one is so lazy it feels like cheating.

Move 1 · The echo question（回音問句）

Here's the laziest, highest-return follow-up in the language. You take a chunk of what they just said, and you say it straight back as a short question — usually with a rising ↗.

Echo question（回音問句） = 把對方剛說的一小段話，原封不動變成一個短問句丟回去，通常配上揚語調 ↗。（"You did?↗" / "A whole week?↗"）

You add zero new information. You steal their words. That's the entire trick:

A: We ended up staying till like 3 a.m.
B: 3 a.m.?↗
A: Yeah, I could barely function the next day.

A: I've genuinely never been on a plane.
B: You haven't?↗
A: Nope. First time next month.

A: My flight got cancelled. Twice.
B: Twice?↗
A: I know. I nearly lost it.

A: I made the whole cake from scratch.
B: From scratch?↗
A: Yep, even the frosting.

A: He quit with nothing lined up.
B: Nothing?↗
A: Not a single interview. Bold move.

See the pattern? B never has to invent anything. B just grabs the juiciest word from A's sentence and bounces it back. One breath of effort, and A is talking again.

Echo the hook, not everything

Not every word is worth echoing. Echo the hook — the surprising, interesting bit. Boring word in, boring echo out:

A: I had a sandwich for lunch.
B: A sandwich?↗ ← 怪。三明治有什麼好追問的？

A: I had lunch with my ex.
B: Your ex?↗ ← 現在這個才是 hook。

Same sentence shape. The second one has something worth pulling on. Aim your echo at that.

⚠️ The arrow does the work

Same words, two completely different jobs — and the intonation decides which:

• "Two weeks?↗" (rising) = "tell me more about the two weeks" → throws the ball back.
• "Two weeks.↘" (flat / falling) = "got it, noted" → that's just acknowledging, and it's closer to a backchannel 附和回應（第 3 課）. The ball stays on your side. It can still drop.

⚠️ An echo question is only an invitation when it goes up ↗. Say the exact same words with a flat ↘ and you've quietly ended your turn instead of passing it on.

⚠️ Don't parrot

Echo everything and you sound like a broken chatbot:

A: I went to the gym.
B: The gym?↗
A: …yeah. Then I grabbed lunch.
B: Lunch?↗
A: (slowly backing away)

Echo once in a while, on the good stuff. When nothing's worth echoing, switch to Move 2.

How it's different from a backchannel（回扣第 3 課）

Backchannel 附和回應（"oh really" / "mm-hmm" / "gotcha"）是萬用的——接在任何句子後面都行，你完全不用動腦。Echo question 剛好相反：它是用對方這一句的字臨時組出來的，只在這場對話裡長得出來。

• Backchannel = 通用零件。"Oh really?" fits after literally anything.
• Echo question = 客製零件。"A whole week?" only exists because they just said a week.

That's the tell: if the reply would still make sense in a totally different conversation, it's a backchannel. If it's stitched from their exact words, it's an echo question.

It blends with reaction（回扣第 4 課）

When the hook is genuinely surprising, an echo question and a reaction 反應語 basically fuse into one move:

A: I won the raffle.
B: You won?↗ No way!
A: Right?! I never win anything.

"You won?" (echo question) + "No way!" (reaction) at the same time — surprise and an invitation to keep going. 不用煩惱該把它歸成哪一類；它們本來就是親戚。

Move 2 · Pick it up, throw it back（撿起來再丟回去）

The echo question is the lazy version. Move 2 is for when you want to steer: instead of bouncing their word back, you ask an open question built from their content.

Hunt the hook, then pull on it

Every sentence has a hook — the one word or detail that's begging for a follow-up. Your only job is to grab it:

A: I finally quit my job to go travel around Vietnam for a few months.

Hooks in there: quit · Vietnam · a few months. Pick one and pull:

• "Wait, you quit?↗" → echo, on quit
• "Nice — what made you finally pull the trigger?" → open, on quit
• "Ooh, whereabouts in Vietnam?" → open, on Vietnam
• "A few months?↗ Lucky you." → echo, on the time

There's no single "right" one. Grab whichever hook you're actually curious about, and the ball's back in the air.

The magic word: So…

Stick So… in front of a follow-up and it means "carrying on from what you just said." It quietly tells the other person I was listening — and then?

• So then what happened?
• So how'd it go?
• So what did you end up doing?
• So are you gonna do it again?
• So what's the plan now?

A little bank of throw-it-back lines to keep on hand:

💡 how'd / what'd / gonna 這些是 reduction 縮讀——自然語速下音節被壓掉了。這一課先把它們當耳朵的輸入聽熟就好，第 8 課再正式拆開講。

⚠️ Lean open, but let tone rescue yes/no

Open questions (how / what / where / who…) can't be killed with one word, so they roll:

• "How was Kyoto?" → they have to paint a picture.
• "Was Kyoto good?" → "Yeah." (ball drops)

But it's not a hard rule. A yes/no question works fine when your tone begs for the story — an echo question is technically yes/no ("You drove?↗") and it's one of the best invitations there is, because the ↗ screams "I need to hear this." So: lean open, but if you go yes/no, let intonation do the inviting.

Putting it together（接住 → 丟回去的組合技）

Now stack this on top of 第 3–5 課. A natural reply often has three quick beats, all in one breath:

1. buy time — "Oh—", "Wait,", "Huh," (filler 填充詞，第 5 課)
2. catch it — "No way!", "Oh nice", "Ugh" (backchannel / reaction，第 3、4 課)
3. throw it back — echo question or open follow-up (本課)

A: I'm running my first full marathon on Sunday.
B: Wait— a full marathon?↗ That's awesome. How're you feeling about it?
A: Honestly? Terrified.

Beat by beat: "Wait—" (filler) · "a full marathon?↗" (echo question) · "That's awesome" (reaction) · "How're you feeling about it?" (open follow-up). Four tiny moves, one breath, and the ball is flying back.

Here's a longer rally. Notice A is never clever — A just keeps catching and throwing back, almost entirely with B's own words:

A: So how was your weekend?
B: Honestly? I spent most of it helping my brother move.
A: Oh no↘, the whole weekend?↗
B: Pretty much. He's got, like, a thousand books.
A: A thousand?↗ How did you even move all that?
B: Rented a van. Made three trips.
A: Three trips↘… you're a good brother. So is he all settled now?
B: More or less. Still boxes everywhere, but yeah.

Count the throws: the whole weekend?↗ · A thousand?↗ · How did you move all that? · is he all settled now? — a whole conversation built out of nothing but B's own words, caught and lobbed back.

Watch out（別把閒聊變成審問）

The number-one way follow-ups go wrong: you fire question after question, and small talk turns into 審問 / a job interview.

❌ Interrogation mode:

A: I went to Kyoto last month.
B: When?
A: June.
B: Who with?
A: My sister.
B: How long?
A: A week.
B: (A is now planning their escape)

Every question is grammatically perfect. It still feels like a police report — all short, all bang-bang-bang, and B offers nothing of their own.

✅ Let it breathe — drop in a reaction and a little something about you between questions, and ask one at a time:

A: I went to Kyoto last month.
B: Oh nice, I've been dying to go — how was it?↗
A: So good. The temples were unreal.
B: Ugh, I can imagine. Did you make it to the bamboo forest?
A: Yeah! Way more crowded than I expected though.
B: Ha, everywhere is these days. I went to Osaka a couple years back — same deal.

Same curiosity, but now there's a rhythm: reaction + a bit of yourself + one open follow-up. That's a chat, not a form.

⚠️ And read the room. If someone gives a short, flat answer and clearly wants to drop a topic, don't keep drilling the same hook. Follow-ups are for pulling on threads people want to pull on. When a thread goes dead, let it die — or just move to a new one (換話題 topic-shift，之後的課會教). Even the best tool has an off switch.

Train your ear first（輸入優先的練法）

第 1 課就講過 input-first 輸入優先：先聽熟、認得出，再求產出。追問延伸也一樣——先在別人的對話裡「看得出球是怎麼被丟回去的」，你自己才丟得出來。

🔧 Recognition first（先練認得出）
回頭掃一遍這課每一段對話，幫每個 B-line 貼標籤：這是 backchannel（第 3 課）、reaction（第 4 課）、echo question，還是 open follow-up？你會開始看見那個節奏：catch → throw back, catch → throw back.

🔧 Spot the hook
找一段英文 podcast 或 YouTube 訪談的逐字稿，挑五句受訪者說的話，把每句的 hook 圈出來，替每句寫一個 follow-up。先不用開口——先練「一眼看到 hook」。

🔧 Echo drill
這一週，跟任何人講英文時，目標低到不可能失敗：一整場對話裡，成功丟出一個 echo question 就過關。"You did?↗" "A whole week?↗" 一個就好。門檻夠低，你才會真的做。

🔧 One combo a day
挑一個組合技（reaction + open follow-up），例如 "Oh nice — how'd it go?"。今天找一次機會用出來，明天換一個。一天一個，一個月就內建了。

🔧 Hear the ↗（optional）
Echo question 的靈魂是那個上揚尾音。純文字站只能標成 ↗，但你得聽真的。到 YouGlish 搜 "you did" 或 "no way"，連聽五六個真人片段，把那個上揚感記進耳朵。（這是加分，不是唯一途徑——上面的對話你已經讀懂了。）

重點回顧

• 一場對話會冷掉，通常不是因為誰講錯（每句可能文法全對），而是沒人把球丟回去。這就是 correct ≠ natural 出現在「整段對話」層級的樣子。
• Follow-up 追問延伸＝順著對方的話再問一句，把球丟回去，讓對話滾下去。它是第 3–5 課「接住球」（backchannel / reaction / filler）的下一步：接住之後，要丟回去。
• Echo question 回音問句＝把對方剛說的一小段字，原封不動變成短問句丟回去（"You did?↗" / "A whole week?↗"）。零新資訊，偷對方的字就好。它的靈魂是上揚語調 ↗——↗ 才是邀請，平/降 ↘ 只是附和、球會掉。
• 跟 backchannel 的差別：backchannel 附和回應是萬用的（接什麼都行）；echo question 是用對方這句的字客製的（只在這場對話成立）。
• 撿起來再丟回去：抓住每句話的 hook（最欠追問的那個字/細節），用 echo 或開放式問句（"So then what happened?" / "How'd it go?"）追下去。多用開放式（一個字答不掉），但配上 ↗ 的 yes/no 也很好用。
• 別把閒聊變審問：連珠炮的問句、又不透露自己，會像做筆錄。中間穿插 reaction 和一點點自己的事，一次問一句；對方想放掉的話題，就讓它過去。

← 上一課 · 第 5 課 · Fillers 填充詞 um / well / you know / I mean — 邊想邊講、幫自己爭取思考時間的那些小詞。（追問前先用它接住半秒——這一課從頭到尾都在偷用它。）

下一課 → 第 7 課 · Softeners 緩衝軟化：把話說得不那麼衝 一直追問，難免問到比較私人或尖銳的事。下一課學怎麼把問句和意見說軟——softener 緩衝軟化與 hedge 模糊限定（sort of / kind of / I guess / maybe），留餘地、不逼人。
