Unit 1 Cultural HeritageSection Ⅱ Discovering Useful Structures——定语从句——一、定语从句的关系词1．关系代词的用法Is he the man who/that wants to see you?他就是想见你的那个人吗？I know a boy whose father is an acrobat.我认识一个男孩，他父亲是杂技演员。Can you show me the photo which/that was taken in the West Lake?你能让我看看那张在西湖拍的照片吗？2．关系副词的用法(1)when 引导定语从句的用法。当先行词是表示时间的名词(如 time, day, year, month, week 等)，且关系词在从句中作时间状语时，定语从句用 when 引导。when 可以用“介词＋which”替换。如：I still remember the time when I was in college.我仍然记得我上大学的那段时光。I have forgotten the exact date when( ＝ on which)this country became independent.我忘记这个国家独立的确切日期了。(2)where 引导定语从句的用法。当先行词是表示具体地点的名词 (如 place, room, mountain, airport 等)或抽象地点的名词(如 case, state, condition, point, situation等)，且关系词在从句中作地点状语时，定语从句用 where 引导。where 可以用“介词＋which”替换。如：This is the hotel where (＝in which) they stayed.这就是他们住的旅馆。We have reached a point where a change is needed.我们到了必须改一改的地步。(3)why 引导定语从句的用法。当先行词是表示原因的名词 reason，且引导词在从句中作原因状语时，定语从句用 why 引导。why 可以用 for which 替换，why 只能引导限制性定语从句。如：This is the reason why (＝for which) he left hurriedly.这就是他匆匆离去的原因。[技巧微博]用关系代词还是关系副词完全取决于关系词在从句中所作的成分，若关系词在从句中作状语，则用关系副词，否则用关系代词。如：I'll never forget the days when I worked together with you.我永远不会忘记和你一起工作的日子。I'll never forget the days that/which I spent in the countryside.我永远不会忘记在乡下度过的日子。3．关系代词用 that 不用 which 的情况(1)当先行词是 all, everything, anything, nothing, much, few, little, none 等不定代词时。如：I told him all t...
