5–8 minutes
Learn the core expressions and record in short blocks.
Name materials and a papermaking method.
Distinguish improving a method from inventing something first. Follow the papermaking sequence with 先、再 and 接着, then find what happens before paper is formed. You can pause after any study block and continue later.
Inventions & story choices · Lessons 9–12
Connect a person’s actions, circumstances and contribution. Separate a retold anecdote from a documented achievement.

5–10 minutes
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: 皮 · 记 · 纸 · 材.
