冊 1｜基礎骨架
時態與情態是 C1 的底盤：重點不是「背公式」，而是**在生活與房產／投資場景裡選對時間視角與語氣強度**。
現在簡單 vs 現在進行
Present Simple vs Present Continuous
過去簡單 vs 現在完成
Past Simple vs Present Perfect
未來：will / be going to / 進行式
Future: will, be going to, Present Continuous
情態動詞：能力、義務、推測
Modals: Ability, Obligation, Deduction
條件句：真實、假設、後悔
Conditionals: Real, Unreal, Past Regret
被動語態：何時該用
Passives: When They Help (and When They Don't)
不定詞 vs 動名詞
Infinitives vs Gerunds
關係子句精簡
Relative Clauses (and Reducing Them)
冊 2｜句子怎麼長得自然
C1 的差異常在「主詞是否清楚、連接是否像美國人思考順序」，不是單字量。

問句與附加問句
Questions & Tag Questions (Softening)
