1．A．what B．that
(1)He telephoned Mary __B__ he wanted to see her.
解析：引导从句作telephoned的直接宾语，that无词义，不充当成分。
(2)This is __A__ I want to say and that is all __B__ I want to do.
解析：第一空what引导表语从句，代词作用的连接代词，在从句中作say的宾语；第二空that引导一个定语从句，修饰all，that可以省略，在定语从句中作do的宾语。
(3)The coffee we had today was different from __A__ we had yesterday.
解析：what引导一个从句作介词from的宾语，充当连接代词引导宾语从句，在从句中作had的宾语。
