主谓一致是英语语法中最基础的规则之一，确保主语和谓语动词在人称和数上匹配。以下是关键要点：

一、基本规则

  1. 单数主语 → 动词用第三人称单数形式

    • 例：She loves apples.
    • 例：The cat sleeps on the sofa.
      ⚠️ 注意：当主语后接 with, along with, together with 等短语时，动词仍与主语一致
    • 例：The teacher is here with her students.

  2. 复数主语 → 动词用原形

    • 例：They play football every weekend.
    • 例：The children are laughing.

二、特殊情形

  • 集体名词（如 team, family）：

    • 作单数时：The team is winning.
    • 作复数时：The team are arguing among themselves.

  • 不可数名词：

    • 例：The water is boiling.

  • 数学表达式：

    • 例：5 + 3 = 8 is correct.

三、常见错误

  • ❌ He go to school every day.
    ✅ He goes to school every day.

  • ❌ The news are exciting.
    ✅ The news is exciting.

  • ❌ The group are arriving.
    ✅ The group is arriving.（若强调集体行动）
