一、用适当的关系代词填空： 1. We need comrades _____________ can help us. 2. The man __________you saw yesterday was a doctor from Beijing. 3. This is a story about a communist fighter ___________ name 或 the name of _____________ is Liu Hu-lan. 4. This is our classroom， _____________ windows 或 the windows of _____________ face the south. 5.

Task2 when where why 的功能
（一）关系副词 where 引导的定语从句。 where 引导的定语从句其先行词往往是表示地点的名词。 例：China is the only country where wild pandas can be found. This is the house where I lived two years ago.
知识拓展： 1. 关系副词 where 引导的定语从句可以转换为“介词+which”引导的定语从句。 例：The hotel where we stayed wasn’t clean. ＝The hotel at which we stayed wasn’t clean The house where LuXun once lived is being repaired now =The house in which LuXun once lived is being repaired now. 难点：① 若定语从句的先行词是地点，但定语从句缺主语或宾语，用 which 或 that 引导定 语从句，而不用 where 来引导。 如：The library that/ which you visited yesterday was built in 1990. ②如果定语从句分别修饰 point, situation, stage, condition 和 case 等表示抽象意义的词， 常用 where 引导，意思是“到了某种地步，在某种境况中”。 例： I’ve come to the point where I can’t stand him.
【典型例题】 1. It’s helpful to put children in a situation _______ they can see themselves differently.
? 难点 ：知识拓展： ? 1. 关系副词 why 引导的定语从句可以转换为“for +which ”引导的定语从句。 ? This is the reason why ( = for which ) I didn’t come here. ? 2. 若定语从句的先行词是 reason，但定语从句缺主语或宾语，则用 which 或 that 引导定语从句。 ? The reason that/ which she gave was not true. 即学即用 1) The reason ________he didn’t come was that he was ill. 2) The reason ________he explained is not true. 规律归纳 1. 判断是否使用关系副词，并不是看先行词是不是时间，地点或原因，而是看先行词是否在定语从句中 是做状语成分，即需要补上一个介词 2. 关系副词=介词+冠词代词（注意：在介词之后，指人的只能用 whom 指物的只能用 which） 真金不怕火来炼！ ！试试吧
1. This is the mountain village _____ _ I visited last year. 2. This is the mountain village _______ I stayed last year. 3. This is the mountain village _____ __ I stayed in last year.
