🧠 FULL TEACHING-LEVEL EXPLANATIONS (ALL 15)
🧩 1. is always punctual
Structural reason:
Frequency adverb shows habit: always = 100%.
Meaning logic:
“Starts exactly on time” signals the strongest frequency.
Rhetorical effect:
Professional reliability tone.
Why others fail:
• never → opposite meaning
• sometimes → weak frequency
Exam note:
IELTS speaking often tests frequency adverbs for naturalness.
🧩 2. sometimes submit late
Structural reason:
Adverb before main verb (submit).
Meaning logic:
“but not every week” = not always, so sometimes.
Rhetorical effect:
Balanced academic reporting.
Why others fail:
• often → could work, but “not every week” suggests occasional
• always → contradicts
Exam note:
Always/sometimes contrasts appear in listening questions.
🧩 3. is usually clean
Structural reason:
Usually = high frequency, but not 100%.
Meaning logic:
Safety importance suggests regular behavior.
Rhetorical effect:
Institutional routine tone.
Why others fail:
• never → impossible with safety context
• too → degree, not frequency
Exam note:
Confusing frequency vs degree is a common A1 trap.
🧩 4. was very difficult
Structural reason:
Very modifies adjectives (difficult).
Meaning logic:
Beginners struggled → high intensity.
Rhetorical effect:
Academic evaluation.
Why others fail:
• always → frequency, wrong category
• enough → “sufficient,” different meaning
Exam note:
Very vs too vs enough is an essential trio for exams.
🧩 5. is often tired

Often = frequent, not always.
Meaning logic:
Long experiments commonly cause tiredness.
