总之,虽然 "in which"、"on which" 和 "at which" 的意义相似,但它们在语法、用法和含义上都存在细微的差异。在实际应用中,需要根据具体语境和需要来选择正确的短语。
"in which","on which" 和 "at which" 都是用来引导定语从句的介词短语,它们之间的区别在于介词所表示的位置关系不同:
"In which" 引导的定语从句中,介词 "in" 表示位置在某一范围内。例如:"The house in which I grew up was very small." (我成长的那个房子非常小。)。
"On which" 引导的定语从句中,介词 "on" 表示位置在物体表面。例如:"The table on which the book is placed is made of oak."(这本书放在橡木桌子上)。
"At which" 引导的定语从句中,介词 "at" 表示位置在一个特定点上。例如:"This is the restaurant at which we had dinner last night."(这就是我们昨晚吃晚餐的那个餐厅。)
需要注意的是,这些介词短语仅适用于指物的情况,若是指人,则需使用 "who" 或 "whom" 引导定语从句。
