She said (that) she would leave a note on the desk. 【结论】 陈述句作宾语时，宾语从句用that引导。that只起连接作用，没有实际意义，在从句中不充当成分，因此常可省略。 that不能的省略 （1）当宾语从句的主语是that I know that that is a book of lisa’s. (2）当宾语从句前面有插入语时 The boss says, at the meeting,that he wants to thank all of us. （3）当宾语从句是双宾语中的直接宾语时 He doesn’t tell his mother that he want to go swimming. 引导词if/whether 2. I don’t know whether / if I should take his advice. He wants to know if / whether you are a doctor. 【结论】 当宾语从句在语意上是一般疑问句或者选择疑问句时，宾语从句用 if 或 whether 引导。它们在句中的意思是是否, 在从句中不充当任何成分，但不可省略。 一般来说，在宾语从句中if与whether可以互换使用。但在特殊情况下，两者不能互换。 只能用whether，不能用if引导的情况： 1) 在介词的后面 e.g. I’m thinking of whether we should go to see the film. 2) 与or not直接连用,或者句尾有or not e.g. I don’t know whether or not they can get there on time. 3)在动词不定式之前 They couldn’t know whether to go right or go left. 当主句是一般现在时，宾语从句的时态不作限制，我们可以根据句子的意思来使用需要的任何一种时态。 三、宾语从句中时态的变化 I hear (that) Jim went to work an hou
