宾语从句是一种名词性从句，在句中作及物动词的宾语，或介词的宾语，或形容词的宾语，或位于间接宾语之后。
宾语从句在初中英语语法中有着相当重要的地位，几乎每年的中考都有对宾语从句不同角度的考查。
其考查的重点一般都集中在以下几个方面：一、考查宾语从句的引导词宾语从句的连接词分为三类：1.若由陈述句转化而来的宾语从句，其引导词由that引导；不过that只起引导作用，无具体意义，在口语或非正式文体中常省略.eg:1.He said (that) he wanted to stay at home.他说他想呆在家里。
2.I am sure (that) he will succeed.我相信他会成功。
2.当宾语从句由一般疑问句变来时，其引导词由if或whether引导，意为“是否”，表示选择。
Eg:1.I want to know if (whether) he lives there.我想知道他是否住那儿。
2.He asked me whether (if) I could help him.他问我是否可帮帮他。
whether和if用法巧计：主从表从同位从，if不用whether用；discuss加介后，whether引导宾语从；不定式，or not后面跟，whether独能显神通；宾从如时否定句，if发挥其功用；避免歧义要慎重，其他情况可换用。
注意：在引导宾语从句时，if和whether一般可换用，但在下列几种情况下只用whether，不用if。
⑴当or not紧随引导词之后时。
Eg:1.We didn't know whether or not she was ready.我们不知道她是否已经做好准备。
⑵当从句用作介词宾语时。
Eg:1.I am interested in whether he joined the army.我对他是否入伍很感兴趣。
⑶当宾语从句移至句首表强调时。
Eg:1.Whether this is true or not, I'm not sure.这是否真实，我不敢肯定。
4.在不定式前用whetherEg:I don’t know whether to stay here.（不过if可引导条件状语从句，whether则不可。
）3.当宾语从句由特殊疑问句变来时，则特殊疑问词便是引导词（如who/whose /what /which;when/where/why/how等），它们均充当一定成分，一般不可省略。
Eg:1.Do you know who (whom) they are waiting for?你知道他们在等谁？2.Can you tell me where the No.3 bus stop is?你能告诉我三路车站在哪儿？3.I don’t know why the train is late.我不知道火车为什么晚点了？注意：引导词的选择应依据句子成分及具体语境。

Do you know ___it is?A. whoseB. whichC. who二、考查宾语从句的语序无论主句是陈述句还是疑问句，也无论主从句之间是什么引导词，宾语从句一律用陈述句语序即“引导词+主语+谓语+其他”结构。
从句中不会出现像do,did,does这三个无意义的助动词。
常用的出题形式为单项选择题、句型转换题（直接引语转换为间接引语此类的题）。
Eg:1.I think (that) you will like this school soon.我认为你不久就会喜欢这所学校。
2.Can you tell me how I can get to zoo?你能告诉我怎样才能到达动物园好吗？3.Please tell me when we’ll have the meeting.请告诉我什么时候开会。

2.Do you know how Kate came here?你知道凯特怎么来这儿的吗？3.Tell me at what time the ship is leaving.告诉我船什么时候出发？2.若主句是一般过去时态,宾语从句只能用过去的某种时态,如一般过去时、过去进行时、过去将来时或过去完成时。
(即：主过从过)4.He said that he would go back to the U.S. soon.他说他不久就返回美国3.如果宾语从句所陈述的是客观事实、普遍真理、自然现象、名言、警句等，则不管主句是何种时态，从句常用一般现在时。
Eg:1.Our teacher said that January is the first month of the year.我们老师说January是一年中的第一个月。
2.Scientists have proved that the earth turns around the sun.科学家已证实地球绕着xx转。
4.以could/would等开头的句子，要看成一般现在时(是一种委婉说法)，不可看成一般过去时。
(即：情态动词could / would用于“请求”，表示委婉、客气的语气时，从句时态不受主句的约束。
)Eg:1.Could you tell me? How can I get to the post office? (合并成宾语从句)→Could you tell me how I can get to the post offlce? (其中can不可改为could)2.Excuse me, could you tell me when we will visit the new Olympic Center?宾语从句的时态练习题：1-5.BCB 6-A 11-17 CAAACCC1.—Could you please tell me ___?—It’s next to the post office.A.whereisthesupermarketB.wherethesupermarketisC.wherethesupermarketwas2.Do you know ___ this time yesterday?A. what she is doingB. what was she doingC. what she was doing3.Oh, this is really a big shop.
