    Root --> Object[宾语从句]
    Root --> Predicative[表语从句]

五、从句选择决策图

flowchart TD
    Start{需要修饰/补充什么？}
    
    Start -->|名词| AdjClause{是什么词？}
    Start -->|整个句子| AdvClause{什么逻辑关系？}
    Start -->|名词位置| NounClause{什么成分？}
    
    AdjClause -->|人| WhoCheck{在从句中作？}
    AdjClause -->|物| WhichCheck{限制性？}
    
    WhoCheck -->|主语| Who[who/that]
    WhoCheck -->|宾语| Whom[whom/who/省略]
    WhoCheck -->|定语| Whose[whose]
    
    WhichCheck -->|是| Restrictive[which/that]
    WhichCheck -->|否| NonRestrictive[which<br/>有逗号]

六、从句与虚拟语气关联

graph TB
    subgraph Conditionals[条件状从]
    IfReal[真实条件<br/>If + 现在, 将来]
    IfUnreal[虚拟条件<br/>If + 过去, would]
    IfPast[与过去相反<br/>If + had done, would have]
    end
    
    subgraph Subjunctive[虚拟语气标记]
    Wish[wish + 过去式]
    Suggest[suggest + (should) do]
    IfOnly[if only + 过去完成]
    end
    
    IfUnreal --> Subjunctive
    IfPast --> Subjunctive
    
    %% 常见结构
    Note1[as if + 过去式] --> Subjunctive
    Note2[would rather + 过去式] --> Subjunctive

七、新概念英语从句分布

timeline
    title 新概念英语从句学习进度
    section L1-L32
        定语从句入门 : L28
        时间状从 : L9
    section L33-L64
        条件状从 : L40
        原因状从 : L49
        宾语从句 : L39
    section L65-L96
        同位语从句 : L85
        主语从句 : L87
        非限制性定从 : L82
        结果状从 : L53

八、从句易混淆点对比

flowchart LR
    subgraph Confusion[易混淆对比]
    A[定语从句 vs 同位语从句]
    B[时间状从 vs 定语从句]
    C[原因状从 vs 定语从句]
    end
    
    A --> A1[定语从句: 修饰先行词]
    A --> A2[同位语从句: 解释名词内容]
    
    B --> B1[状从: 修饰整个句子]
    B --> B2[定从: 修饰时间名词]
    
    C --> C1[状从: 说明原因]
    C --> C2[定从: 修饰reason名词]

九、关系词选择速查表

先行词主格宾格所有格备注
人who/thatwhom/who/省略whose正式文体用whom
物which/thatwhich/that/省略whose非限制性只用which
时间--when= 介词+which
地点--where= 介词+which
原因--why= for which
