在英语定语从句中，当关系代词（which/whom/whose等）作介词宾语时，介词的处理方式主要有以下三种情况，需特别注意语法结构和逻辑关系：

一、介词前置（正式文体）

将介词移至关系代词之前，此时关系代词不可省略，且只能用 which（指物）或 whom（指人），不能用 that 或 who。

结构：先行词 + 介词 + which/whom + 从句其他成分

例句：

The book to which I referred is out of print.（我提到的那本书已绝版。→ refer to sth.）The scientist with whom we collaborated won a Nobel Prize.（我们合作过的那位科学家获得了诺贝尔奖。→ collaborate with sb.）

注意：

介词前置时，不可用 'that'：❌ The house in that I lived → ✅ The house in which I lived.二、介词后置（非正式文体）

将介词保留在从句末尾，此时关系代词可省略（若作宾语），且可用 that/who/which 或直接省略。

结构：先行词 + 关系代词（可省略） + 从句（介词在句尾）

例句：

The book (which/that) I referred to is out of print.（口语中更常用，关系代词可省略）The scientist (who/that) we collaborated with won a Nobel Prize.

注意：

介词后置时，关系代词若为宾语可省略：✅ The man (who) I talked to is my boss.三、固定短语中的介词

若介词是动词短语不可分割的一部分（如 look after, take care of），通常不拆分，介词必须后置。

例句：

The children whom she takes care of are orphans.（✅ 正确，take care of 不可拆分）❌ The children of whom she takes care... （不自然）This is the project which our team will look into.（✅ look into 为固定短语，介词不前置）特殊注意事项关系代词 'whose' + 名词 + 介词：The company whose logo you're familiar with is Apple.（✅ 介词后置，因 'whose logo' 是一个整体）

2. 'where/when/why' 替代 '介词 + which'：

The city in which I grew up → The city where I grew up.The day on which we met → The day when we met.

3. “介词 + 关系代词 + 不定式”结构

规则：先行词为抽象名词（如 way, time, place）时，可用“介词 + which + to do”简化从句。例句：She needs a place in which to study.（= a place where she can study）I have no money with which to buy food.（= no money to buy food with）

4. 关系副词替换

规则：当“介词 + which”表示时间/地点/原因时，可用关系副词 when/where/why 替换。例句：The day on which we met → The day when we met.The house in which I lived → The house where I lived.错误修正示例

❌ This is the house in that I was born.✅ This is the house in which I was born.或 This is the house (that) I was born in.

❌ The person to who I gave the letter is absent.✅ The person to whom I gave the letter is absent.或 The person (who) I gave the letter to is absent.

总结选择原则正式写作/学术文体：优先介词前置（e.g., in which）。口语/非正式文体：介词后置，可省略关系代词。固定短语：介词必须后置，保持短语完整性。 本站仅提供存储服务，所有内容均由用户发布，如发现有害或侵权内容，请点击举报。
