定语是来修饰名词或代词的,状语是来修饰动词,形容词,副词和整个句子的。如
he is a tall boy. 这句中tall作定语修饰后面的名词
he go to school on foot这句中. on foot作状语修饰谓语动词
there is a book in the bag. in the bag作地点状语
the boy standing at the door is my brother. standing at the door作定语修饰前面的名词
I have something important to tell you. important作定语修饰前面的代词。
定语是修饰限制名词代词的成分,状语是说明动作的时间,方式,原因,频度等的成分。
例如:That is the company I work in.中I work in说明的是名词company,是定语。
I always go to the park.中 always 说明的是go这个动词的频度,是状语。
教你一个顺口溜,谓前为状谓后补,定语放在主宾前。谓语通常都是动词,主语和宾语通常都是名词。
