宾语从句（一） 宾语从句在复合句中作主句的宾语。宾语从句常由that引导，在口语中常省略。 当主句中谓语动词是现在或将来时态时，从句中谓语动词不受主句中谓语动词时态的 影响，按需要可以使用任何时态。如： She says (that) she works from Monday to Friday. 她说她从周一至周五上班。（从句是一般现在时） She says (that) she will leave a message on his desk. 她说她要在他桌子上留个便条。（从句是一般将来时） She says (that) she has never been to Mount Emei. 她说她从来没有去过峨眉山。（从句是现在完成时） 当主句谓语是过去时态，从句中的时态一般用表示过去的某种时态。如： He said there were no classes yesterday afternoon. 他说昨天下午没有课。（从句是一般过去时） He said (that) he was going to take care of the baby. 他说他会去照看这个婴儿。（从句是过去将来时） He said (that) they were having a meeting at that time. 他说他们那时正在开会。（从句是过去进行时） *当主句谓语是过去时态，而宾语从句叙述某一客观真理（事实）时， 宾语从句的时态则用一般现在时。如： The teacher told us(that) nothing is difficult if you put your heart into it. 老师告诉我们世上无难事只怕有心人。 She said (that) her father is twenty-eight years older than her. 她说她父亲比她大二十八岁。 He said that light travels much faster than sound. 他说光传播比声音传播快得多。 宾语从句（二） 由连接代词或连接副词引导的宾语从句。 引出名词性从句的连词whether和if，在引出宾语从句时，用法和意义相同。但是只能引出宾语从句和不在句首的主语从句，而whether除了引出宾语从句外，还可引出主语从句、表语从句和同位语从句。例如： We don't know whether (if) it is right. 我们不知道它是否正确。 The question is whether she should do that. 问题在于她是否应该做那件事。 Whether it is true remains a question. 是真是假还是个问题。 试比较： 当if从句处在主句之后作“是否”讲时，引出的是宾语从句。例如： I don't know if it is true. 我不知道这事是否真实。 当if从句在主句之前作“如果”讲，则引出状语从句。例如： I shall go there if I have time. 如果我有时间，我将到那儿去。

宾语从句，在复合句中作宾语，位于及物动词后；
eg． Tell him which class you are in ．
Do you know what he likes？
注：(1)主、从句时态一致：
主句谓语过去时，从句相应过去时；
He answered that he was listening to me.
主句谓语现在时，从句时态任所需；
eg． He says (that) he will leave a message on my desk.
They know (that) he is working hard.
具体过去永不变，真理格言现在时；
eg．He told me that he was born in 1980.
Father told me that practice makes perfect .
（2）否定前移，及完成反意问句；
在think / believe / suppose / guess / imagine / expect等动词后跟宾语从句否定式时，应转移到主句上去，完成反意问句时，应与从句主、谓保持一致。（注: 否定前移的条件是，主句主语是第一人称）
eg． I don't think you are right ,are you ?
I don't believe they have finished their work yet,have they ?
（3）在表示建议 suggest , advise
要求demand 、desire、require、request、propose；
决定 decide;
命令 order、command;
坚决主张 insist;
等动词后跟宾语从句，用（should）+v．（虚拟语气）
eg． I suggested that you（should）study hard．
He ordered that we should go out at once．
（4）如果宾语从句后有宾语补语，用it作形式宾语，把宾语从句后置
eg．You may think it strange that he would live there．
（5）宾语从句that常可省略，但在以下情况下不能省略
A．当主句谓语动词带有两个或两个以上宾语从句时，可以省略第一个that，其他不能省略。
eg．I believe（that）you have done your best and that things will get bet?鄄ter．
B．当it作形式宾语时
eg．She made it clear that she had nothing to do with him．
C．当宾语从句前置时
eg．That our team will win，I believe．

宾语从句:当句子的宾语是一个主谓结构,(即一个分句)时,这个分句就叫称宾语从句.全句是包涵宾语从句的复合句.
that, who ,whether,if,who,whose,which,when,where,how,why 引导.
I hope (that) you can come tomorrow .
He asked me whether\if I knew Zhang Hua.
其实就是个主谓宾结构,但是宾语必须是个从句就可以了.
