in which的用法及例句有哪些？

“in which的用法及例句有哪些?”——in which是英语中引导定语从句的核心结构，它的作用是替代先行词被修饰的名词，并在从句中充当“地点状语”或“抽象情境中的状语”。具体用法可分为两类，对应不同的先行词类型：

一、修饰“具体地点”，作从句的地点状语

当先行词是具体的地点名词如town、house、café、room等时，in which相当于“in + 先行词”，直接说明动作发生的物理地点。例如：

• She pointed to the park in which they used to play as kids.她指向他们小时候常玩的那个公园。
• The restaurant in which we celebrated your birthday is now a bakery.我们庆祝你生日的那家餐厅现在变成了面包店。
• I found the key in the drawer in which I keep my old letters.我在放旧信件的抽屉里找到了钥匙。

  二、修饰“抽象概念”，作“在...中”的状语

  更常见的是，in which用于修饰抽象名词如situation、environment、period、way、report等，此时它不再指向具体空间，而是“在某种情境、时期或方式中”。例如：
  • He was caught in a dilemma in which he had to lie to protect his friend.他陷入了必须撒谎保护朋友的两难境地。
  • The school created a culture in which students feel safe to ask questions.学校营造了一种让学生敢于提问的文化氛围。
  • We are living in an era in which AI is reshaping every industry.我们正生活在一个AI重塑所有行业的时代。
  • The manual in which the instructions are written is on the shelf.写有说明的手册在书架上。
  • There’s a pattern in which people tend to procrastinate before deadlines.有一种规律是，人们在截止日期前总会拖延。

    与“where”的差异

    当先行词是具体地点时，in which可与where互换where更口语，in which更正式；但抽象概念的先行词只能用in which，不能用where。例如：
    • The café in which / where we met is still open.我们见面的咖啡馆还在营业——具体地点，可互换
    • The situation in which he found himself was impossible to solve.他所处的局面法决——抽象概念，不能换where 再举几个覆盖不同场景的例句：
      • I flipped through the album in which our wedding photos are stored.我翻了翻存着我们 wedding照片的相册。
      • The factory in which my mother worked for decades is now a shopping mall.我妈妈工作了几十年的工厂现在变成了商场。
      • She recalled the day in which she first held her newborn baby.她回忆起第一次抱新生儿的那一天——day虽为时间，但“in the day”是固定搭配，故用in which 简言之，in which的本质是“介词+关系代词”，它的用法核心是连接先行词与从句，并在从句中补充“in + 先行词”的逻辑关系——论是具体地点，还是抽象的情境、时期或方式，只要从句需要“in + 先行词”来整表达意思，就可用in which引导。
