5、定语从句的使用语境。二、While-class教师活动：介绍限制性定语从句。定语从句()关系副词的用法当引导定语从句的关系词在从句中用作时间、地点、原因状语时，应使用关系副词when, where, why或“介词which”。关系副词的作用如下：1指代表示时间、地点、原因的先行词。2在从句中充当句子成分状语，即在从句中起副词的作用。3起连接作用，把主句和定语从句连接起来构成主从复合句。一、关系副词引导定语从句1when引导定语从句when表示时间,代替先行词并在定语从句中做时间状语，其先行词往往是表示时间的名词，如time, day, year, month, week等。2where引导定

6、语从句where表示地点, 代替先行词并在定语从句中做地点状语，其先行词往往是具体地点place, room, mountain, airport或抽象地点的名词如case, state, condition, point, situation等。3why引导定语从句的用法why表示原因, 代替先行词并在定语从句中做原因状语，其先行词是表示理由的名词reason。二、关系代词与关系副词的选用定语从句的引导词用关系代词还是关系副词可以用以下两种方式判断：用法依据根据从句的谓语动词是及物动词，后面若无宾语，用关系代词；是不及物动词则用关系副词根据先行词在从句中所作的成分把先行词代入定语从句中，若作

7、主语或宾语用关系代词；作状语则用关系副词This is the factorywherehe used to work.这是他以前工作过的那家工厂。(work是不及物动词)This is the factory(that/which)I visited last year.这是我去年参观过的那家工厂。(visit是及物动词)Is this the museum(that/which)you visited a few days ago?这就是你几天前参观的那家博物馆吗？(从句缺少宾语)Is this the museumwherethe exhibition was held?这就是举办展览的

8、那家博物馆吗？(从句缺少地点状语)三、介词+关系代词引导的定语从句关系副词when, where, why引导定语从句时，关系副词也可用“介词+关系代词“代替。（1）when可以换成“介词which”。I still remember the timewhen_(in_which)I was in college.我仍然记得我上大学的那段时光。I have forgotten the exact datewhen_(on_which)this country became independent.我忘记这个国家独立的确切日期了。(2)where可以换成“介词which”。This is the

9、 hotelwhere_(in_which)they stayed.这就是他们待过的旅馆。(3)why可以用for which来代替。This is the reasonwhy_(for_which)he left in a hurry.这是他匆匆的原因。1、介词选择的三原则：一先二动三意义。一先：根据先行词的搭配习惯来确定。二动：根据从句中谓语动词的搭配习惯来确定。三意义：根据从句所表达的意义来确定。2、介词可以后移，此时关系代词可以忽略。3、名词/代词/数词+of+关系代词 引导的定语从句通常是非限制性定语从句，该结构在定语从句中一般作主语。活动目的：帮助学生梳理、归纳关系副词when,

10、where，why与先行词的关系,理解/in/on/at/during+which”引导定语从句的意义。三、After-class学生活动：Complete the passage with the correct relative adverbs or pronouns.Add a preposition where necessary.When I started studying German,it was a struggle.The words felt strange on my tongue,and the grammar would not stay in my head.I
