GrammarThe Relative Clause定语从句定语从句的基本概念1定语从句是整个句子充当定语,来修饰名词或代词。被定语从句所修饰的词叫先行词，定语从句一般紧跟先行词。定从一般用关系代词或关系副词引导，关系词在含义上替代先行词,并在定语从句中充当一个成分。定语从句的基本概念2The manwhocame to see me this morning is my cousin.今天早晨来看我的人是我表弟.先行词定语从句关系代词作主语，不可省定语从句的基本概念3关系代词：代人:who（主语/宾语），whom（宾语）代物:which（主语/宾语）代人或物:that(主语/宾语)Whose某人的/某物的,（先行词的所有格)；关系代词在从句中做主语，不能省略;做宾语，可以省略。定语从句的基本概念4关系副词：Where表示地点，在定从中作地点状语;When表示时间，在定从中作时间状语;Why表示原因，在定从中作原因状语。关系代词whichwho / whomthat关系副词whenwherewhy诀窍:先找定语从句所修饰的先行词;再判断定从里缺少成分吗?如缺成分,缺的是什么成分?主语还是宾语?1.

The old woman has two sons, and one of _____ is a professor.(1. whom,2. them)CLASSICAL QUESTIONS @,@3. Do you know why he was absent?（宾从）4. Do you know the reason why he was absent?（定从）5. Do you know the reason which (that) may explain his absence?（定语从句）以上三句含义相同，句式不同。CLASSICAL QUESTIONS @,@6. The reason that you were ill yesterday is not accepted.（你昨天生病的原因没有被接受。）这是一句“同位语”从句的句子，“reason”与“you were ill yesterday”表达的是同等意思，因此关系词不能用“which”，只能用“that”。CLASSICAL QUESTIONS @,@7.The news that our team won the game made us excited.（我们队赢的消息使我们激动.同位语从句）8. The news which (that) I heard through the radio is exciting.（我从广播中听到的消息令人激动.定语从句）CLASSICAL QUESTIONS @,@9.定语从句中的插入语He made a speech, whichI thoughtwas of great importance.Jimmy is the boy, whoeverybody believeswill win the first prize in the singing competition.CLASSICAL QUESTIONS @,@在上述句子中，I thought, everybody believes是插入语，还有I suppose, everybody knows等在定语从句中出现，容易受其迷惑而用错关系词。比如在上述第二句中就不能用“whom”，因为“who”是从句的主语，而“everybody believes”是插入语。因此在有插入语的定语从句中，考虑用什么关系代词或副词时，可暂时不考虑插入语，以免受其迷惑。The End!大结局!谢谢观赏!
