如果宾语从句中有某个含有否定意义的形容词或副词,其反义疑问句要用肯定形式.
We find that he never listens to the teacher carefully,does he? 我们发现他从来不仔细听老师讲课,是不是?
八、宾语从句的时态和语序
当主句为现在时或将来时,宾语从句的时态一般不受主句的时态所影响. 当主句为过去时
①从句用一般过去时或过去进行时表示与主句谓语动词动作同时发生
I only knew he was studying in a western country,but I didn’t know what country he was in.
我只知道他当时在西方的一个国家读书,可不知道是哪个国家.
He asked me if I was reading the story The Old Man and the Sea when he was in.
他问我他进来的时候我是否正在读<<老人与海>>. ②从句过去完成时表示该动作发生在主句谓语动作之前
He told me that he had told Mary about the meeting already. 他告诉我他已经把有关会议的事情告诉了Mary.
③从句谓语用过去将来时表示该动作发生在主句谓语动作之后
The reporter asked if the government would take necessary measures to put down the to-do.
记者问政府是否会采取必要的措施镇压骚乱.
如果从句是一个客观真理,那么从句的时态不根据主句的时态而变化 The teacher said that the moon goes around the earth yesterday. 老师昨天说月亮绕着地球转.
当宾语从句的引导词是who,which,what,when,where,how,why等表疑问时,不能按正常语序安排,经常将这类引导词置于句首
Who do you think the public might choose as their favorite singer this year?
你认为今年公众会选谁为他们最喜欢的歌手.

宾语从句（版本二）
学习宾语从句要抓住三要素：连接词、语序和时态。
1.连接词
1．从句为陈述句，常选择连接词that或将that省略，直接与主句相连。
2．从句为一般疑问句，常选择连接词if或whether。在 whether … or not 结构中不能用 if 替换。
3．从句为特殊疑问句，常选择what,when,where,which,who,how等的疑问代、副词作连接词。
注意：当who为主语时，句式为：who+谓语+其他
2.判断时态情况：
1.主句是一般现在时，从句为各种时态情况。
2.主句是一般过去时，从句为各种相应过去时态注意：从句描绘客观事实，用一般现在时。 eg:
1. The teacher told the children that the sun＿＿＿＿ round. A. was B. is C. were D. are
2. I believe that our team＿＿＿＿ the basketball match. A. win B. won C. will win D. wins
3. I don’t know＿＿＿＿ to visit the old man. A. whether B. if C. that D. who
4.The soldiers soon reached( )was once an old temple( )the villagers used as a school.
A.which;where B.what;which C.where;which D.what;where
答：选B，动词reach后接宾语从句，从句缺少宾语，where不可，which引导宾语从句时表疑问含义“哪一个…”而此句中并非疑问含义，不知道哪一座庙宇，而是用what从句表陈述含义，意“过去的一座旧庙宇”；temple后为对其修饰的定语从句，用关系代词which代替，并在从句中作动词used的宾语，use sth. as…“把…用作…
宾语从句用作宾语。如： Do you know where he lives?
定语从句相当于一个形容词，用于修饰前面的名词。如：
The student who answered the question was John. 回答问题的学生是John.
This is the man whom he is looking for. Do you know the girl who is in red?

3.宾语从句的用法
1.that引导宾语从句无意义，不充当句子成分常省略。但下列情况除外： （1）介词宾语从句的that不省略
（2） and连接的几个从句，第二个从句以后的从句的that不省略。 He told me that he had two sons and that they both had gone to college.
（3）在动词+it+宾语补足语+宾语从句结构中，that不省略。 I heard it said that he had gone abroad
We found it impossible that he could finish it in such a short time 2.Whether ,if 引导宾语从句：两词可互换，但是下列情形除外： （1）whether从句中有or not （2）whether从句做介词宾语
Everything depends on whether you agree with us
3.许多带复合宾语的句子，宾语从句经常移到句子后部，而用it做形式宾语。结构常是：
主语+动词+it+形容词/名词等宾语补足语+宾语从句 We think it wrong that he told a lie to everyone 4.宾语从句的语序要用陈述句语序
False: He is wondering when can he finish this difficult job. Right: He is wondering when he can finish this difficult job. B 有时候可以用it 作形式宾语，而把真正的宾语从句放在后面。
Bad: I thought that he could finish this job in just two hours impossible.
Good: I thought it impossible that he could finish this job in just two hours.
Bad: He left whether we should continue this project to my judgment. Good: He left it to my judgment whether we should continue this project.
C 带有宾语从句的复合句的否定形式一般是否定主句。 Bad: I think he doesn’t like the English teacher. Good: I don’t think he likes the English teacher.
D 主句一般过去时态，从句也要用过去时态；具体细节请看第一部分。 False: He wanted to know why he is crying in the corner. Right: He wanted to know why he was crying in the corner.

宾语从句（版本三）
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）运用虚拟语气的情况
在表示：
建议 suggest 、advise、propose; 要求demand 、desire、request； 决定 decide;
命令 order、command、require; 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）宾语从句后置情况
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）宾从中that不可省略的情况
宾语从句that常可省略，但在以下情况下不能省略
