Say “Grade III” as “grade three,” “3A” as “three A,” and pronounce *sān jí jiǎ děng* and *sānjiǎ* as Mandarin terms. Leave brief, natural pauses between ideas. Do not add or omit words.Warm and alert, with a slight smile in the voice. Moderate energy, around 135–145 English words per minute. Begin as if pointing out a useful clue, not reading a manual. Give “Grade III, Class A” a little emphasis. Make the final two questions sound genuinely curious, with a small lift in pitch and a clean pause between them. Keep the tone grounded and trustworthy.
