Hook inherited from 主題句.

框 · Frame

[topic]，[a complete comment about it]

觸 · Trigger

You want to raise a subject first, then ask or say something about it, without the subject filling any slot in that sentence.

序 · The move

1put the thing you want to talk about at the very front, baredoes it set what the rest is about, rather than fill a slot in it?

2cut it loose with a pause (a comma in writing)could the part after stand as a full sentence on its own?

3make the comment within that frame, echoing the topic with a measure or pronoun if neededdoes the comment stay about the fronted topic?

例 · Examples

Pens — how much each?

主題句

話題優先 fronts a standalone frame, cut off by a pause; the comment is a complete sentence with no slot for it (筆，幾塊錢一枝呢？). 主題句 fronts an argument the comment acts on, filling a slot in it (這本書我看完了 — 看 takes 這本書). Frame-setter against argument-topic.

是…的

話題優先 raises the subject of talk and leaves the comment open. 是…的 foregrounds one detail of a settled event by clamping it between 是 and 的. Set the topic against spotlight one detail.

treating the topic as the verb's object: 幾塊錢一枝買筆呢 → 筆，幾塊錢一枝呢（topic stays out front, comment self-stands）

burying the topic mid-sentence: 你覺得筆貴不貴 → 筆，你覺得貴不貴（front it, pause, then comment）

forcing a subject-verb-object frame onto a frame-setting topic: 西瓜很多人喜歡 stated as 很多人喜歡西瓜 loses the topic reading → 西瓜，很多人喜歡（西瓜 set as frame first）

English leads with a grammatical subject and keeps every noun in its slot, so learners rebuild the bare fronted topic into a subject-verb-object clause and lose the aboutness it carried.
