当宾语从句出现在 believe， expect， imagine， suppose， think 等动词之后且表示否定含义时，宾语从句中的否定一般会转移到主句中进行表达，例如:I don't believe that he will leave.
The tall man is my father. Who is the tall man ?Jerry always did her homework after supper. When did Jerry always do her homework ?
它可以作动词的宾语，也可以作介词的宾语，还可以作“be+形容词”的宾语.例如:动词宾语:He said he was good at drawing.这里“he was good at drawing”作动词“said”的宾语.
