I still remember the time when I was in college.2. we will never forget the day when we flew at an altitude of 6000 meters in the sky.,1. when引导的定语从句,当先行词为表示具体地点的名词(如：place, house, airport等)或抽象地点的名词(如：point, case, situation, stage, position, condition等) ，且关系词在从句中作地点状语，定语从句用where引导。,1.

This is the student for whom I bought a book.2. This is the ship by which I went to Shanghai.,2. 在“介词+关系代词”引导的定语从句中，关系代词只能用which或whom,不可用that/who。先行词指物时用which，先行词指人时用whom。,3. “名词，不定代词或数词 + of + which (指物)/whom (指人)”在定语从句中作主语，说明整体中的一部分。,1. China has lots of islands, one of which is Hainan Island.2. The building had been repaired, the roof of which was destroyed again in a big fire.3. Miss Liu has a lot of students, some of whom are girls.,(二)选用介词的依据1. 根据先行词的搭配或从句中的动词、形容词等的搭配(即固定短语)。(1)Yesterday we visited the West Lake for which Hangzhou is famous.(2) He is the student from whom we should learn.(3) I remember the days during which I lived here.(4) I cant remember the age at which he won the prize.2. 根据句子的意思来选择。(1) This is the pilot with whom my brother has worked for ten years.(2) This is the pilot by whom my son was saved.,课堂小结（2）,注意：一些表示抽象地点的名词，如 point，case，position，condition，situation等 用where 引导,when,where,why,指时间，在定语从句中充当时间状语,指地点，在定语从句中作地点状语,指原因，在定语从句中作原因状语,当堂检测（15）,用恰当的关系代词，关系副词或“介词+关系代词”完成句子。1.
