英语定语从句和宾语从句有什么区别?

定语从句和宾语从句的区别老大啦.
1.从定义上区别.定语从句用来修饰名词和代词.如这个句子He who doesn't reach the great wall is not a true man,说定语从句有3要素先行词,关系词,主谓一致性,这个句子为例,先行词是被修饰的代词he,关系代词是who,句子主语是he所以谓语用单数is.宾语从句3要素：时态、语序(陈述句语序）、连接词.He told me that he would come soon.
2.从位置来看.定语从句放在名词代词之后,翻译成.的；宾语从句是放在动词之后.
3.从成分上来区别.定语从句作定语；宾语从句作宾语
4.我想你真正想问的是定语从句与同位语从句的区别对吗?
比较下面两个句子
1.He made a promise that he would give me a present.
2.He made a promise that he could not keep.
这两句子的区别时1是同位语从句,that,链接作用,不充当成分；2句是定语从句,that在句子中作keep的宾语是关系代词代替promise.在定语从句中that 做成分,代替先行词,链接句子；在宾语从句中that 起连接作用而已.
希望你满意这个答案.
