→ 抽象名词专用:news/story/information/fact

(2) 定语从句 vs 同位语从句辨析

类型引导词功能例句
定语从句that修饰具体名词The story [that he told us] is not true. (他讲的故事不真实)→ that在从句中作宾语(told的宾语)
同位语从句that解释抽象名词内容The story [that he was a hero] is not true. (他是英雄的说法不真实)→ that后为完整句子,解释story内容

(3) 状语从句

      The evidence [that the vaccine works] is clear. (疫苗有效的证据很明确)
    • ✘ 误用:抽象名词 + where/when → ✓ 同位语从句只用that
  2. 五大句型核心规则

    • S+V+O+OC(宾补):补语直接修饰宾语(president说明him
      • 补语类型:名词/形容词(They painted the wall blue
    • S+V+O+O(双宾):物(直接宾语)必为人(间接宾语)服务
      • 句型转换:He gave a gift to her(介词结构)
  3. 定语从句与同位语从句的区分

    判断标准定语从句同位语从句
    that的作用在从句中充当成分(主/宾)仅引导,不作成分
    名词类型具体事物(story, book…)抽象概念(news, fact…)
    删减测试从句不完整:he told [ ]从句完整:he was a hero
