The 把 construction is mandatory in specific structures — not optional stylistic flair. These three traps cover the cases 排词成句 (Q86-95) tests most. Part of the 15 high-frequency HSK 4 traps collection.

6. 把字句 is mandatory with 「verb + 在 + place」
When a placement verb is followed by 在 + a location (放/挂/写/装/贴/停 etc.), the object must move before the verb via 把. The SVO form is ungrammatical — not just unnatural. (Note: 坐 follows a different pattern — 我坐在椅子上 is fine without 把 because 坐 is positional, not placement.)
✗ 我放书在桌子上。 — Ungrammatical. The verb 放 with 在 + location obligatorily requires 把.
✓ 请把窗户关上。 Qǐng bǎ chuānghu guān shàng. — 请 functions as the polite imperative subject.
HSK 4 NEW pattern flag: 把 + O + V一V (tentative action) is one of the 4 new 把字句 patterns at HSK 4. V一V itself is HSK 3 vocabulary, but using V一V inside a 把字句 is HSK 4 NEW. Don't confuse the two layers.
Double-object verbs traditionally do not take 把字句 — but real HSK 4 listening and reading use the 把 form regularly. Both are accepted in testing. Know which is canonical.
Canonical (recommended for writing): 他告诉了我这件事。 Tā gàosu le wǒ zhè jiàn shì. — Standard SVO with double object.
Real HSK 4 usage (recognize when listening): 他把这件事告诉了我。 Tā bǎ zhè jiàn shì gàosu le wǒ. — 把字句 form, emphasizes 这件事.
HSK 4 grammar note: Strict prescriptive grammar says 告诉/教/给/问 should not use 把字句 — they're double-object verbs that don't need fronting. However, HSK 4 dialogues and passages use the 把字句 form when emphasizing the affected object. Recognize both; default to the canonical 告诉了我这件事 form when writing Q86-95. Exception: 给 with a direct-object recipient is fully canonical with 把: 把书给我 ✓ (very common, not a "trap"). The non-canonical pattern is mainly 告诉 / 教 / 问 with 把.
"I put the book on the desk." Pick the grammatical form:
When the verb has 在 + location (放/挂/写/装/贴/坐 etc.), the object MUST be moved before the verb via 把. 我放书在桌子上 is ungrammatical, not just unnatural. The third option misorders 把 + 在 + V.
Unlike English, HSK 4 把字句 imperatives still need an explicit subject (你 / 我 / 请). The first option drops 你 — graders mark it wrong on 排词成句. The third option misorders V一V outside the object slot.
"He told me this matter." Which form is most canonical for HSK 4 writing (Q86-95)?
Both option A and option B are accepted in HSK 4 listening/reading, but option B (canonical SVO with double object) is the safer choice when writing. 告诉/教/给/问 are double-object verbs — strict prescriptive grammar prefers them outside 把字句. The third option is ungrammatical.
