※ 引述《kirel (Fly dream)》之铭言： 罗嗦一下好了，有误请多指教 首先我习惯简化题目，以便解释文法 因此我把原句做以下的简化 (准备不看的部分先括号起来) 原句: It is essential to reform the system for determining the prices at which the state purchases and sells grain (and to take further steps to regulate the stockpiling of grain). 简化1: It is essential to reform the system for determining the prices at which the state purchases (and sells) grain. 两次简化後的句子: It is essential to reform the system for determining the prices at which the state purchases grain. 上面这句可拆成两句: (把which看做是代替the prices的关系代名词) 1. It is essential to reform the system for determining the prices. 2. The state purchases grain at the prices. 由上面拆成的两个句子可以看出 若原句没有at这个介系词，则拆不成两个句子 也就无法将两个句子用关系代名词合并成一个句子 (或是你可以将上面两个句子反过来合并成一个句子，如下: It is essential to reform the system for determining the prices which the state purchases grain at. 然後将介系词放到关代前面 (原因为什麽有请高人解释) 就变成了: It is essential to reform the system for determining the prices at which the state purchases grain. 这个方式去想) 至於你的at which = when 的认知，可能得去将文法书看仔细 并非每次看到at which都能将他想成when eg1: This is the desk at which I sit. = This is the desk where I sit. eg2: The cat at which he is angry is mine. 以上是我的见解 请多指教 : 请问以下句中at which的意思: : it is essential to reform the system for determining the prices at which : the state purchases and sells grain and to take further steps to regulate : the stockpiling of grain. : 我的认知是at which=when : 因此翻译为: : 为了决定国家买卖谷物时的价格，改革体系十分重要…… : 又at which的at是否可省略呢? : 谢谢大家 -- --
