三、选择介词的逻辑依据

  • 根据覆盖物性质:

    • 物质/薄层 →with(如雪、灰尘)
    • 整体性物体 →by(如毯子、合同)
    • 液态/密集覆盖 →in(如血、雾)
  • 根据句法结构:

    • 被动语态(动作执行者明确)→by(例:The road was covered by snow.
    • 系表结构(描述情形)→with/in(例:The ground is covered with snow.
  • 根据覆盖程度:

    • 完全遮蔽 →by(例:The window was covered by soot.
    • 部分附着 →with/in(例:The table was covered with papers.

四、易错点与纠错建议

  • 混淆被动语态与系表结构:
    误:The table was covered with a cloth by her.(正确但冗余,可简化为 She covered the table with a cloth.
    正:The table was covered by a cloth.(强调动作)

  • 错误搭配:
    误:The child was covered by mud.(应为in,因泥浆是液态物质)
    正:The child was coveredin mud.


选择介词时需综合覆盖物的物理特性、句子结构及表达意图。例如,强调动作来源用by,描述情形用with 或in。实际使用中可结合语料库高频搭配验证。
