Lead-in Knowledge explanation Lead-in Knowledge explanation 关系副词的定义 关系副词，顾名思义，是联系先行词和定语从句的词，属于副词。定语从句中的关系副词有三个：when, where和why，它们在定语从句中分别作时间、地点和原因状语。 Lead-in Knowledge explanation 关系副词的句法结构 表时间的名词 + when + 定语从句 when指时间，在定语从句中作时间状语。 例句：I still remember the day when I first came toBeijing. I’ll never forget the day when I joined the army. Lead-in Knowledge explanation 关系副词的句法结构 表地点的名词 + where + 定语从句 where指地点，在定语从句中作地点状语。 例句：The factory where his father works is in the west of the city. This is the house where I lived two years ago. Lead-in Knowledge explanation 关系副词的句法结构 表原因的名词reason + why + 定语从句(why只用于reason之后的限制性定语从句中,在定语从句中作原因状语。) 例句：That is the reason why I did the job. (在现代英语中why可以省略) That is the reason I did the job. 又如： This was the reason (why )we raised the temperature. Lead-in Knowledge explanation 关系副词在定语从句中的用法 1）“when”、“where”和“why”的运用取就于表时间的名词、表地点的名词和表原因的名词reason在定语从句中所作的成分，比较下面的几组句子： *I will never forget the day when I first met you on the seashore. *I will never forget the days which/that we spent together inXueyaoMiddle School. Lead-in Knowledge explanation 关系副词在定语从句中的用法 2)“when”、“where”和“why”都可以替换成“介词 + which”，介词的选用取就于先行词和定语从句中的动词。例如： Do you still remember the day on which we first met in Nantong? (on which=when) This is the room in which we lived last year.(in which=where) Lead-in Knowledge explanation 关系副词在定语从句中的用法 3)关系副词“when”、“where”既可引导限制性定语从句，也可引导非限制性定语从句。 例如：I will always remember the day when I first visited the Great Wall. He came toShanghaiin 1980, when he was only 12. I don’t know the exact spot where they will meet. Lead-in Knowledge explanation 关系副词在定语从句中的用法 4)“that”可活用为关系副词，相当于“when, where、why”和“介词 + which”结构，尤其在“the time when”等结构中的“when”常被“that”代替，而且“that”往往省略。 I may leave here any time I want to. During the time I was there I visited him twice. Lead-in Knowledge explanation 关系副词在定语从句中的用法 5)“which”有时可用作关系形容词，这是“which”在非限制性定语从句中的特殊使用，如： The doctor advised him to give up smoking, which advice he did not follow. 03.
