Practise the writing focus and revisit your first-choice answers.
Try each item in a short block. Listen when needed, record when ready, and use the hints to retry. Pinyin and English can be turned off independently.
Pinyin shows how to say a word. The mark above a vowel shows its tone.
Watch the tone marks and listen for the rhythm of the whole phrase. Light syllables are short; pauses belong between meaningful groups.
Flip each card for stroke order. This lesson’s writing focus: 为 · 因 · 所.
