如何选择定语从句的引导词_非常有用!

如 何 选 择 定 语 从句的引导词? *限制性定语从句 限制性定语从句修饰先行词，对先行词起修饰作用，紧接先行词之后，无逗号，若省去，原句意思不完整。引导定语从句的关系代词有who,whom,whose,which,that 等。who,whom,whose 用于指人，whose 有时也可指物，相当于of which；which 用于指物；that既可指人也可指物，但只用于限制性定语从句中。关系代词除了引导定语从句，替代先行词外，还在从句中担任主语、宾语、定语等。 *非限制性定语从句 非限制性定语从句既可修饰先行词，也可修饰整个主句，起补充说明作用，与主句之间有逗号隔开，若省去，原句意思不受影响。不可用that 引导非限制性定语从句。关系词不可省略。 一、定语从句的引导词有关系代词who， whom，whose，which，that， as；关系副词when， where，why。定语从句中引导词的选用主要看先行词在定语从句中作什么成分或者是定语从句中缺什么成分。 1．定语从句中缺主语，修饰人时用who ／that，修饰物时用which ／that 引导。如： Is this the factory which ／that makes TV sets？ The man who ／that visited our school is from Australia． 2．从句中缺宾语，修饰人时用 who ／whom ／that 或省略引导词；修饰物时用which ／that 或省略引导词。如： Gone are the days which ／that we spent together in the village． He is the man who ／whom ／that I think to be worthy of our praise． 3．从句中缺时间状语，用when 或介词＋which 引导。如： The day finally came when ／on which I was given a job． We'll put off the outing until next week，when we won't be so busy． 4．从句中缺地点状语，用where 或介词＋which 引导。如： Please put the letter on the desk where ／on which he can easily find it． 5．从句中缺原因状语或先行词是 reason 时，引导词用why ／for which ／ that。如： This is the reason why ／for which ／ that he didn't come to the meeting． 6．从句中缺定语，人和物都用 whose 引导。如： A child whose parents are dead is called an orphan． Please pass me the dictionary whose cover is black． 7．当先行词是way时，其定语从句的引导词...
