b) 从结构上讲,that在同位语从句中为连词,不充当句子成分;而在定语从句中that代替先行词在从句中充当主语、宾语等句子成分 


c) 有些引导词如whether, what, how等可以用来引导同位语从句,但它们不能用来引导定语从句 


d) 可作同位语从句的先行词的名词比较有限,常见的有doubt, fact, message, proof, opinion, hope, impression, evidence, idea, belief, feeling, conclusion, rumour, report, possibility, guarantee, thought, assurance等。而定语从句的先行词则比较广泛,包括大部分名词及代词
