1.以上六个句子都使用了“ ”引导的定语从句。先行词若指物，那么介词后的关系代词用 ；若指人，则用 。2.以上六个句子中，句2,3,4,6是 定语从句，句1,5是 定语从句。
一、基本构成在“介词＋关系代词”结构引导的定语从句中，关系代词指物用which，指人用whm，不可用that或wh代替。There cmes Tm，fr whm I have been waiting an hur r s.汤姆来了，我等了他大约一个小时。He handed me a pen with which I wrte dwn his phne number.他递给我一支钢笔，我用它记下了他的电话号码。The university in which my brther nce studied is very famus.我哥哥曾经就读的大学很有名。
二、“介词＋关系代词”引导的定语从句关系代词作介词的宾语时，为了使关系代词与先行词的关系更加紧凑，可以将从句中的介词提到关系代词前，形成“介词＋关系代词”的结构。该结构中的关系代词可用which，whm 或whse。1.介词的选用(1)依据定语从句中动词或形容词等所需要的某种习惯搭配来确定。Yesterday we visited the West Lake fr which Hang-zhu is famus.昨天我们游览了西湖，杭州因其而出名。(2)依据与先行词搭配的具体意义而定。I’ll never frget the time during which I spent my childhd in the cuntry.我永远不会忘记我在乡村度过的童年时光。
(3)根据所表达的意思来确定。The clrless gas withut which we cannt live is called xygen.这种无色的、离了它我们就无法生存的气体叫作氧气。温馨提示有些“动词＋介词”短语如lk fr，lk after，call n等，如果介词提前将会失去动词短语的意义，所以不可把介词置于关系代词前。Is this the bk which she was lking fr?这就是她在找的那本书吗？The babies whm the nurses are lking after are healthy.护士们照看的婴儿都很健康。
2.“名词/数词/代词等＋介词f＋关系代词”结构有时“介词＋关系代词”前还会有名词、数词、代词等，表示部分、整体、数量等概念。The river，the banks f which are cvered with trees，flws t the sea.这条河流入大海，河两岸都是树。The ld wman has tw sns，bth f whm are dctrs.这位老太太有两个儿子，他们都是医生。
