they all和all of them有什么区别?

They All 与 All of Them 的用法差异析 在英语语法中,"they all" 和 "all of them" 都表示“全部”,但两者在语法功能和使用场景上存在显著差异。 They all 由主格代词 "they" 与副词 "all" 构成,主语的整体性。在句中,they all 通常置于句首,直接充当主语,后接谓语动词。例如:
  • They all attended the meeting.
  • They all share the same opinion. All of them 是由限定词 "all"、介词 "of" 和宾格代词 "them" 构成的名词性短语,独立充当句子成分。其核心功能是指代前文提及的复数名词,通常位于动词或介词之后作宾语。例如:
    • The teacher praised all of them.
    • I bought gifts for all of them. 当 all of them 位于句首时,需意主谓一致,谓语动词用复数形式。例如:
      • All of them are members of the club.
      • All of them have completed the project. 在转换句式时,"they all" 与 "all of them" 可构成同义句,但语法角色不同。例如:
        • They all agreed → All of them agreed.
        • They all passed the exam → All of them passed the exam. 尽管语义相近,二者不可随意替换。"they all" 不能用作宾语,"all of them" 不能直接替换主语位置的 "they all"。例如:
          • 正确:She invited all of them.不能说 She invited they all
          • 正确:They all arrived early.不能说 All of them arrived early 需调整语序 核心差异: 1. 语法结构:"they all" 是“主格代词+副词”;"all of them" 是“限定词+介词+宾格代词” 2. 句中位置:"they all" 以主语身份置于句首;"all of them" 多以宾语身份位于动词或介词后
