1、定语从句,关系副词的用法及定语从句用法的其他要点,一.当关系词在定语从句中做状语时，要用关系副词。其中when=表时间的介词（in/on/at/during等）+which;why=表原因的介词（如for)+which;where=(表地点的介词in/on/at/under等）+which. 如； I still remember the day when I first cameto Beijing. (when=on which) Can you tell me the office where he works?,(where=on which) Do you know the reas
2、on why he is absent? (why=for which) 二.where/when=介词+关系代词（which)有时为了表达清楚，还可以在关系副词where/when前加介词from/to等。 China is the birthplace of kites,from where Kite flying spreads to Japan,Korea,Thailand and India.,Look over there.Some people are standing under the big tree,from where we enjoy the whole view.
3、分析：where代表under the big tree这个地方，如果用which就只能代表the big tree,这句话的意思不是Enjoy the view from the big tree而是from under the big tree所以只能用from Where,She climbed up to the top of the hill,from where she could have a good view of the whole town. (from where=from on the top of the hill) Alice stood in front of

5、复杂，从先行词为明显的“地点”转为“模糊化的地点”。,事实上，对于where 这个词不能只理解为标地点。当先行词为situation/case/stage/point等，且先行词在定语从句中做状语时，也要用关系副词where 引导。 They have reached the point where they have to separate with each other. Lets think of a situation where his idiom can be used.,I have reached a point in my life where I am supposed t
6、o make decisions of myself. Those successful deaf dancers think that dancing is an activity where sight matters more than hearing. 四.关系代词和关系副词的比较 关系代词和关系副词在定语从句中除了其连接主句和从句的作用外，他们换在定语从句中担当句子成分。关系代词在定语从句中担当主语，宾语，,定语、表语，而关系副词在定语从句中作状语。因此，在选择关系词时最主要的是分析定于才能根据中所缺的成分，如果从句中缺少主语，宾语，定语，表语就选关系代词，如果缺少状语就选关系副词。
