从句接在状语后的叫状语从句，接在宾语后是宾语从句，如下面一个句子成分：i主语 told谓语 him a story宾语 that day状语。在句子宾语成分后加上一个句子成分就变成宾语从句：I told him a story that a woman was hurt in an accident that day.在句子状语成分后加上一个句子成分就变成状语从句：I told him a story that day my friend have gone out。

宾语从句是名词性的，将其去掉以后，主句不再是个完整的句子，有残缺。状语从句式修饰性的，去掉它不影响句子在语法上的完整性。*************纠正楼上的错误说法：从句位于状语之后不一定就是状语从句，如He is locked in a room that nobody knows. 此句中从句为定语从句，但是跟在状语in a room之后。位于宾语之后的也不一定就是宾语从句，如I know the room where he is locked. 此句中从句为定语从句，但是跟在宾语room之后。
