It was a time when people were divided geographically. 2. Emperor Qinshihuang united the seven major states into one unified country where the Chinese writing system began to develop in one direction. 3. There are many reasons why people learn a foreign language. 4. These were animal bones and shells on which symbols were carved by ancient Chinese people. Step 2. Presentation 关系副词 time 时间状语 place reason 地点状语 原因状语 作状语，即从句成分齐全，不缺主，宾，表，定语。 引导定语从句的关系副词包括when, where, why，一般代替先行词在从句中作状语，表示时间、地点、原因。 The time when I arrived. The mines where I worked. The reason why I got a job. 关系副词 指代 在从句中充当的成分 例句 when where why Eg：I still remember the days when we swam together in the river. 总结关系副词的作用： 指代表示时间、地点、原因的先行词 连接主句和从句 在从句中充当句子成分—状语 先行词 （表示时间） 关系副词 （作状语） 定语从句 关系副词 如何区分关系代词和关系副词引导的定语从句： 表示时间、地点及原因的名词作先行词时, 关系词在定语从句中作状语时, 用关系副词; 若关系词在定语从句中作主语、宾语时, 则用关系代词。 方法：分析从句句子成分 关系副词 Eg: The accident has reached to the point both their parents are to be called in. 关系副词 — where特殊用法 关系副词 where 还可用在表示抽象意义的地点名词后, 如 situation (情形), stage (阶段), point (地步), case (情况), position (位置), condition, activity, scene, occasion等,意思是“到了某种地步, 在某种境况或情况中” 。 where 重要提示 并非所有的表示时间、地点、原因的先行词，后面的定语从句都用when和where引导。如果定语从句中缺少主语或宾语，就要用that或which引导。 This is the house _____ my father built last year. Do you still remember the days _____ we spent in the countryside that/which that/which 关系副词 结论： 先行词表时间、地点、原因 关系词在从句中作状语 判断先行词在从句中的成分，用正确的关系词填空。 The reason _____ he gave us was quite reasonable. This is the reason _____ he went. This is the place _____ we visited last year. This is the place _____ he works. That was the time _____ he arrived. Do you still remember the time _____ we spent together which/that where when that/which why/for which that/which 关系副词 定语从句三步解体法： 一、划出定语从句； 二、判断关系词在从句中做的成分———主宾表：关系代词；状：关系副词 三、根据先行词确定关系词 定 语 从 句 的 引 导 词 关系代词 关系副词 指人 指物 that(主语/宾语/表语), which(主语/宾语),who(主语/宾语), whom(宾语), whose(定语)，as(主语/宾语/表语) that( ... ...
