定语从句是修饰限定名词或代词的从句，做所限定名词或代词的定语，确实为形容词性从句，因为定语多是形容词嘛。因此，定语从句往往出现在所修饰的名词或代词的后面。如：This is the book that I want. 而宾语从句是做动词和介词的宾语的宾语, 偶尔有一些形容词后也可跟宾语从句，如：sure, afraid等，故往往出现在动词或介词之后。如：I don't know that this is your book.
I'm sure that you are right.

1。定语从句（Attributive Clauses）在句中做定语，修饰一个名词或代词，被修饰的名词,词组或代词即先行词。定语从句通常出现在先行词之后，由关系词（关系代词或关系副词）引出。
关系代词有：who, whom, whose, that, which等。
They rushed over to help the man (whose car had broken down.)
关系副词有：when, where, why等。
I'll never forget the days (when I worked together with you. )

2。宾语从句（Object Clause)在句中作宾语，如：
He believe (that Tom will be back soon.)
I am glad (that you are well again.)
It all depends on( what you do.)
