1、Grammar 形容词：用来修饰描述名词或代词的词,在简单句中，作定语、表语、补足语.定语从句：是一个句子，在复合句中,由关系词引导，相当于一个形容词，修饰名词或代词(先行词)。This is the best film that I have seen.先行词关系词定语从句先行词：被修饰的名词或代词，在定语从句之前.定语从句：先行词之后,修饰先行词.关系词:引导从句,在从句中代替先行词，充当句子成分.定语从句分为限制性定语从句和非限制性定语从句。限制性定语从句是先行词在意义上不可缺少的定语,如果去掉,主句的意思就不完整或失去意义。它和主句的关系十分密切，写时不用逗号分开。在限制性定语从句中作
2、宾语的关系代词常可省略。Toronto is a city(that)I ve always wanted to visit.非限制性定语从句只是对先行词作些附加说明,如果去掉,主句的意思仍然清楚。它和主句关系不十分密切，它与主句之间常用逗号分开,一般不用that引导。l在非限制性定语从句中关系词不可省略。She said she had finished her work,which I doubted very much.Ive got some personal affairs that I have to deal with.注意：that，why不能在非限制性定语从句中使用。as引导
3、非限制性定语从句，可以用在主句前，也可以用在主句后，指代整个主句的内容。常译为“正如，好像”。注意：在某些场合，非限制性定语从句的先行词可为整个主句,此时非限制性定语从句常由which引导。A middle-aged woman killed her husband,whichfrightened me very much.A five-year-old boy can speak two foreign languages,which surprises all the people present.as 和 which引导非限定性定语从句,都可指一句话内容，区别在于which只能放在它所指
4、那句话的后面，而as可以在前面,也可以在后面。which as在引导非限制性定语从句时的区别：1.which可以代指主句的部分内容，也可以代指整个主句的内容。as代指整个主句。2.as引导的非限制性定语从句既可以放在主句之前，也可以放在主句之后。which引导的非限制性定于从句只能跟在主句后，不能放在句首。3.当非限制性定语从句为否定句或者具有否定意义时用which,不用as。4.as表达”正如,就像”之意.如何判断用关系副词还是关系代词?选用定语从句的关系词时，需注意两点：1.先行词2.关系词在从句中充当的成分。做主语、宾语、表语、定语关系代词做状语关系副词the usage of the
