13、于此结构，但介词后置时可以使用。二、介词的选取一般来说，确定关系代词前的介词，可以从以下三方面入手：先行词的意义；从句中的动词或形容词与先行词的固定搭配；句子的意思。Do you know the man to whom our teacher is talking?你认识正和我们老师谈话的那个男人吗？Ill never forget the time during which I spent my childhood in the country.我永远不会忘记孩童时代我在乡村度过的时光。三、“介词关系代词”的特殊用法1表示“整体和部分关系”，介词常用of。在some，any, few, n

14、one, all, both, neither, most, each等代词或数词的前、后可以用of which/whom。John invited about 40 people to his wedding, most of whom are family members.约翰邀请了大约40人参加他的婚礼，他们当中绝大部分是家庭成员。2有时“介词where”可以引导定语从句，此时要和“介词which”引导的定语从句从意思上加以区别。His head soon appeared out of the window, from where he saw nothing but trees.他的

15、头很快从窗口探了出来，从那里除了树木他什么也看不到。(from where相当于from out of the window，而不是from the window)3在定语从句中，含介词的短语动词不可拆开使用(短语拆开后含义发生变化)，如look after，look for等。4“of which/whom”有时可以用“whose名词”结构来改写。5当先行词为way并且定语从句中缺少状语时，通常用in which或that引导定语从句(in which或that可省略)；如果定语从句中不缺少状语，则用关系代词引导(that或which作宾语时可省略)。.单句语法填空1The professo
