🧠 FULL TEACHING-LEVEL EXPLANATIONS (ALL 15)
🧩 1) Do not remove the QR code
Structural reason: “Do not” + base verb.
Meaning logic: A strict prohibition in official instructions.
Rhetorical effect: Formal notice tone (sign/regulation).
Why wrong answers fail:
removes = present simple (he/she/it removes)
removing = -ing form, not an imperative
Exam/academic note: YDS notices often prefer “Do not…” over “Don’t…”
🧩 2) Please fill the form
Structural reason: “Please” + base verb = polite imperative.
Meaning logic: A polite instruction, still an instruction.
Rhetorical effect: Administrative/academic form language.
Why wrong answers fail:
fills = present simple
filling = not a command
Exam note: TOEFL classroom/admin contexts use “Please + verb…”
🧩 3) Let’s not discuss the results yet
Structural reason: “Let’s not” + base verb.
Meaning logic: Group decision to delay discussion.
Rhetorical effect: Collaborative but controlled academic tone.
Why wrong answers fail:
discusses = present simple
discussing = wrong after “let’s not”
Exam note: Lecture discourse often uses “Let’s (not)…”
🧩 4) You must keep your password confidential
Structural reason: “must” + base verb for obligation.
Meaning logic: Mandatory security rule.
Rhetorical effect: Policy/regulation language.
Why wrong answers fail:
keeps = present simple
keeping = gerund/participle
Exam note: Must is common in written rules (YDS-style).
🧩 5) Visitors mustn’t smoke in this area
Structural reason: “mustn’t” + base verb for prohibition.
Meaning logic: Smoking is forbidden.
Rhetorical effect: Strong rule (stronger than “don’t”).
Why wrong answers fail:
smoking = wrong form after mustn’t
smokes = present simple
Exam note: Mustn’t is a high-yield “notice grammar” signal.
🧩 6) You have to wear a helmet
Structural reason: “have to” + base verb.
Meaning logic: Requirement (not optional).
Rhetorical effect: Workplace safety compliance.
Why wrong answers fail:
wears = present simple
wearing = not correct after have to
Exam note: Have to is common in spoken rules (TOEFL style).
🧩 7) Please don’t change the file name
Structural reason: “Please don’t” + base verb.
Meaning logic: Polite prohibition.
Rhetorical effect: Professional instruction tone (lab/computer).
Why wrong answers fail:
changes = present simple
changing = not an imperative
Exam note: “Please don’t…” appears in classroom and tech instructions.
🧩 8) Be careful! Don’t touch the hot surface
Structural reason: Negative imperative: “Don’t + verb.”
Meaning logic: Prevent harm.
Rhetorical effect: Immediate safety warning.
Why wrong answers fail:
Touch = opposite meaning (dangerous instruction)
Touching = not a command
Exam note: Warnings often combine “Be careful!” + “Don’t…”
🧩 9) Check your answers twice
Structural reason: Imperative uses base verb.
Meaning logic: Standard exam instruction.
Rhetorical effect: Procedure/quality-control tone.
Why wrong answers fail:
Checks = present simple
Checking = not imperative
Exam note: IELTS/YDS instructions love “Check / Choose / Write…”
🧩 10) Let’s move to the next question
Structural reason: “Let’s” + base verb.
Meaning logic: Group progression.
Rhetorical effect: Lecture/class transition language.
Why wrong answers fail:
moves = present simple
moving = not correct after let’s
Exam note: TOEFL lectures frequently use this transition.
🧩 11) Do not bring food into the laboratory
Structural reason: “Do not” + base verb.
Meaning logic: Formal prohibition.
Rhetorical effect: Official notice language.
Why wrong answers fail:
brings = present simple
bringing = not imperative
Exam note: “Do not bring…” is classic sign language.
🧩 12) have to be silent
Structural reason: “have to” + base verb; verb is be.
Meaning logic: Rule for behavior during exams.
Rhetorical effect: Strict procedural rule.
Why wrong answers fail:
are = present simple statement, not rule phrasing
being = wrong form
Exam note: “have to be + adjective” is common in rules.
🧩 13) Please return your seat (more natural: “return to your seat”)
Structural reason: Please + base verb.
Meaning logic: Instruction to go back after session/break.
Rhetorical effect: Classroom management.
Why wrong answers fail:
returns = present simple
returning = not imperative
Exam note: Imperatives often appear in announcements.
🧩 14) Don’t open the window
Structural reason: Negative imperative needs “Don’t + base.”
Meaning logic: Window opening causes discomfort (cold).
Rhetorical effect: Direct practical instruction.
Why wrong answers fail:
Not open… is incomplete/unnatural as a standalone command
Doesn’t is wrong subject form
Exam note: “Don’t” is the default negative imperative.
🧩 15) please work in pairs
Structural reason: Please + base verb.
Meaning logic: Classroom task arrangement.
Rhetorical effect: Cooperative instruction.
Why wrong answers fail:
working = not imperative
works = present simple
