宾语从句，是名词性从句的一种。在主从复合句中充当宾语，位于及物动词、介词或复合谓语之后的从句称为宾语从句。下面是给大家整理的宾语从句的简介，希望能帮到大家!
宾语从句的定义
宾语从句分为三类：动词的宾语从句，介词的宾语从句和形容词的宾语从句。
置于动词、介词等词性后面起宾语作用的从句叫宾语从句。宾语从句的语序必须是陈述语序。谓语动词、介词、动词不定式，v.-ing形式后面都能带宾语从句。有些形容词(afraid,sure,glad等)之后也可以带宾语从句。
宾语从句意义
语法是语言的组织规律，任何人在使用语言时，不管他是否学过语法，都须合乎语法。另外，总结语法本身的规律也能加深我们对语言的理解，让我们能够真正熟练地运用语言。(宾语：指一个动作(动词)的接受者，常置于动词之后，也有双宾语结构例句：he gave me a book，类似拥有me和book两个宾语的句子叫双宾语从句)，在复合句中，由一个句子充当宾语，这个句子就叫做宾语从句。

宾语从句可以作及物动词、介词及形容词的宾语。
宾语从句的语序一律用陈述句语序。
连接词that引导宾语从句在句中无词义，不充当句子成分，多数情况下可以省略。

宾语从句，即：在主句中担当宾语的从句。学习宾语从句要抓住三要素：连接词、语序和时态。 连接词一般都是that(指事务或人),which(指事),who(指人)
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…ornot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+其他三：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
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】 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…whether + or not 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?.
B.当it作形式宾语时
eg.She made it clear that she had nothing to do with him.
