【考情分析】
课标要求：
近几年全国各地中考对宾语从句的考查是中考必考考点之一，主要考查的是时态及宾语从句的语序，有时也会考查宾语从句的引导词。考查的主要形式是单项填空、完形填空、短文填空和完成句子。阅读理解和书面表达肯定也会考查到宾语从句。因此学生要熟练掌握宾语从句的用法。
考查题型：对宾语从句的考查主要分布在改错、句子运用、完形填空、词语运用题。
考查重点：1. 引导宾语从句的连词和代词选择；2. 宾语从句的语序；3. 宾语从句的时态。
宾语从句解题技巧如下:
1.牢记宾语从句考点的记忆口诀:
宾语从句需注意,几点事项应牢记。
一是关键引导词,不同句子词相异。陈述句子用that;一般疑问是否(if,whether)替;特殊问句更好办,引
导还用疑问词。
二是时态常变化,主句不同从句异。主句若为现在时,从句时态应看意;主句若为过去时,从句时态应变
相应过;从句若为真理时,永用一般现在时。
三是语序要记清,从句永保陈述序。
2.用好排除法
从时态、语序、引导词三个方面综合考虑,逐个排查选项。
宾语从句题型命题规律
【网络构建】
考向一宾语从句的概说和分类
概说：
1.定义：在复合句中作宾语的从句是宾语从句。
I think everybody likes cookies.
2. 分类：动词宾语从句 I think everybody likes cookies.
介词宾语从句 I agree with what you said just now.
形容词宾语从句 I’m afraid I can’t afford it. (sure, glad, sorry, happy, afraid)
3.结构：主句+引导词+从句(陈述句语序：主+谓+其他)
分类：
根据引导宾语从句的不同连词，宾语从句可分为三类：
1. 由that引导的宾语从句。that只有语法作用，没有实在的意义，在口语和非正式文体中可以省略。
He said (that) he wanted to stay at home.
She doesn’t know (that) she is seriously ill.
I am sure (that) he will succeed.
2. 由连接代词who, whom, whose, what, which和连接副词when, where, why, how引导的宾语从句。这些连接代词和连接副词在宾语从句中充当某个成分。
Do you know who (whom) they are waiting for
He asked whose handwriting was the best.
Can you tell me where the No.3 bus stop is
I don’t know why the train is late.
3. 由if或whether引导的宾语从句。if和whether在句中的意思是＂是否＂。
I want to know if (whether) he lives there.
He asked me whether (if) I could help him.
考向二 宾语从句的引导词
that引导陈述句作宾语从句，口语中常省略。
Tell him (that) I have read the story.
She told me (that) she would like to go with us.
连词if/whether引导一般疑问句作宾语从句，表“是否”，从句陈述语序（主语在谓语之前），且口语中多用if。
Do you know if he will go to school tomorrow
I wonder if /whether you have told the news to Li Lei .
注意：以下情况的宾语从句中，只能用whether，不能用if：
引导词与动词不定式或or not连用时
I’m not sure whether to go or to stay.
He asked me whether or not I was thirsty.
当从句做介词的宾语时
We are talking about whether we'll go on the picnic.
The picnic will depend on whether the weather will be fine.
特殊疑问词引导特殊疑问句作宾语从句，从句同样是陈述语序。
He didn’t know when he would leave for shanghai.
Could you tell me what is wrong with you
that引导的宾语从句
that 是宾语从句的一个引导词，放在主句和从句之间。它引导的宾语从句由陈述句转化而来，故从句的语序不变。在that 引导的宾语从句中，that 作连接代词，无意义，在句中不作任何成分，在口语或非正式的文体中通常可以省略。
一、that 引导的宾语从句的用法
1. 位置：that 引导的宾语从句通常放在主句谓语动词（及物动词）、介词或形容词之后。
①作及物动词，如：say，think，tell，know，hear，see，hope，wish，remember，forget等的宾语。如：　
She says that she will help me learn English this evening.
②作介词的宾语：连词that引导的名词性从句很少作介词的宾语，只用在except，but，in之后。如：
He is a good boy except that he is careless. 他是一个好男孩，只是有点儿粗心。
③作＂be + 形容词＂结构的宾语。某些形容词或过去分词后常接宾语从句，如：sure，glad，certain，pleased，sorry，happy，afraid等，连词that可省略。如：
I’m happy (that) I passed the exam.
2. 时态：主句的谓语动词是一般现在时，从句的谓语动词可根据具体情况选用适当的时态；主句的谓语动词是一般过去时，从句中也必须用过去的某种时态。试比较：
He says that he wants to see him as soon as possible. 他说他想尽快见到他。
He said that he wanted to see him as soon as possible. 他说他想尽快见到他。
【特别提醒】
当主句是一般过去时，而宾语从句的内容表示的是客观真理、事实、科学原理、自然现象、名言警句、格言、谚语等时，此时宾语从句用一般现在时，这些情况下不受主句时态的限制。如：
The teacher told us that the earth goes round the sun. 老师告诉我们地球围绕着太阳转。
3. 如果宾语从句后还有宾语补足语，则用it作形式宾语，而将宾语从句后置。如：
We thought it strange that Xiao Zhang did not come yesterday. 小张昨天没来，我们觉得很奇怪。
4. 宾语从句的否定转移。
在think，believe，suppose，expect等动词后的宾语从句，当主句的主语是第一人称时，谓语尽管是否定的意思，却不用否定形式，而将think等动词变为否定形式，英语称这种现象为否定转移。如：
①我认为今晚他不能来。
【误】I think he can’t come this evening.
【正】I don’t think he can come this evening.
②他认为我们现在不在教室里。
【误】He doesn’t think we are in the classroom now.
【正】He thinks we are not in the classroom now.
【特别警示】
含有＂否定转移＂现象的句子，主句的主语必须是第一人称，此时，变成反意疑问句，附加问句要由从句来决定；如果主句的主语是其他人称，附加问句要由主句来决定。如：
I don’t think he is right, is he 我认为他不对，是吗？
He thinks I can come, doesn’t he 他认为我能来，是不是？
疑问词引导的宾语从句
特殊疑问句作宾语从句时，由疑问词 when, who, what, where, whatever, how，which, why等引导。宾语从句的词序一律用陈述句的词序，即＂主语+谓语＂词序。
①带有系动词be（is，am，are，was,were)的特殊疑问句。
主句 宾语从句
Do you know how old Liz is 你知道兹几岁吗
I know how old Liz is. 我知道莉兹几岁。
I don’t know how old Liz is. 我不知道莉兹几岁。
宾语从句＂how old Liz is＂是主句动词know的宾语。how在从句中作副词。注意从句的顺序，主语在动词前（Liz is)。
②带有（情态）助动词is/am/are/have/has/can/should等的特殊疑问句
When is Ann going to lran 安什么时候去伊朗？
→ Do you know when Ann is going to lran 你知道安什么时候去伊朗吗？
→ I don’t know when Ann is going to lran. 我不知道安什么时候去伊朗。
What should I do 我该怎么办？
→ Can you tell me what I should do 你能告诉我，我该怎么办吗？
→ Please tell me what I should do. 请告诉我，我该怎么办。
Where has Ron gone 朗去了哪里？
→ Do you know where Ron has gone 你知道朗去了哪里吗？
→ I don’t know where Ron has gone. 我不知道朗去了哪里。
③带有助动词do/does/did的特殊疑问句。
Where did I put my wedding ring 我把我的结婚戒指放在哪里了？
→ Do you know where I put my wedding ring 你知道我把我的结婚戒指放在哪里了吗？
→ I don’t remember where I put my wedding ring. 我不记得我把我的结婚戒指放在哪里了。
What does Sue think about Lulu 苏对露露的看法是什么？
→ Do you know what Sue thinks about Lulu 你知道苏对露露的看法是什么吗？
→ I know what Sue thinks about Lulu. 我知道苏对露露的看法是什么。
注意：
（1）由于宾语从句要求陈述句语序，故而在从句中它变成了陈述语序。请看下列两组句子：
How much does this coat cost
→ I want to know how much this coat costs.
Where did you go yesterday
→ Please tell me where you went yesterday.
（2）当疑问代词what、who在特殊疑问句中作主语时，该特殊疑问句本身就是陈述句语序，所以当该句用来作宾语时，语序不需要调整。
What’s wrong with you 怎么了？
→ He asked the girl what was wrong with her.
What’s the matter 怎么了？
→ He asked the girl what was the matter.
What has happened to him
→ We want to know what has happened to him.
if/whether引导的宾语从句
当从句部分是一般疑问句或选择疑问句时，常用if或whether引导宾语从句，if/whether意为＂是否＂。说明对陈述的事物不明确或不清楚。常用在see，ask，say，learn，tell，wonder，doubt，find out，be uncertain /doubtful / be not known 等后，二者通常可以互换。口语中多用if代替whether。在非正式的写作中，可以使用if 或 whether 两个词来表达不定性，两者都算标准。
I wonder if/whether he is a driver. 我想知道他是不是个司机。
Alice wants to know if/whether she has passed the exam. 爱丽丝想知道她是否考试及格了。
Lily asked if/whether she liked it. 莉莉问她是否喜欢它。
I want to know if (whether) he lives there. 我想知道他是否住在这儿。
He asked me whether (if) I could help him. 他问我是否可以帮助他。
【拓展】
一般情况下，if和whether可互换，在口语中多用if， 而在以下几种情况下，只能用whether。
1. 与 or 连用分别引导两个从句时，或强调两方面的选择, 特别是句中有or not时用whether，不用if。
I don’t know whether or not they will come. 我不知道他们是否会来。
I don’t know whether he is wrong or she is wrong.
Let me know whether you can come or not.
I don’t know whether he will win or not.
I will write to you whether or not I can come / whether I can come or not.
2. 在动词不定式之前只能用whether。
He doesn’t know whether to go or not. 他不知道是否会去。
Please tell us whether to go there or stay here. 请告诉我们是去那里还是待在这里。
Whether to go or stay is still a question.
I’m not sure whether to stay or leave.
I didn’t know whether to laugh or to cry.
3. 在介词之后只能用whether引导宾语从句，而If则不能。
It depends on whether I have enough time. 那取决于我是否有足够的时间。
Success depends on whether we make enough effort.
I haven’t settled the question of whether I’ll go back home.
It depends on whether the letter arrives in time.
I worry about whether I hurt her feelings.
4. 宾语从句置于句首表示强调时，用whether，不用if。
Whether this is true, I can’t say. Whether he is single, I don’t know.
Whether this is true, I can’t say.
Whether he is single, I don’t know.
5. 在某些动词（如discuss，decide）之后，只能用whether，而不用if引导宾语从句。
We discussed whether we should close the shop. （虚拟语气）
We discussed whether we should go there by plane.（虚拟语气）
We discussed whether we should hold a meeting. （虚拟语气）
6. 在引导否定概念宾语从句时，只能用if，而不用whether。
He asked me if I hadn’t finished my work.
注意：doubt否定句用that引导。因为don’t doubt 意为相信，不怀疑，if是否表示疑虑。
考向三 宾语从句的时态
如果主句是现在的某种时态（包括一般现在时、现在进行时、现在完成时），那么宾语从句的时
态可根据实际情况而定。记忆口诀：主现从任/主现从不限
I remember he gave me a book yesterday.
He has told me that he’ll leave for New York tomorrow.
I don’t think (that) you are right.
Please tell us where he is.
Can you tell me how I can get to the railway station
如果主句是过去的某种时态（包括一般过去时、过去进行时），那么宾语从句一定要用过去的某种时态（包括一般过去时、过去进行时、过去将来时、过去完成时）。记忆口诀：主过从相过
He told me that he would take part in the high jump.
He asked what time it was.
He told me that he was preparing for the sports meet.
He asked if you had written to Peter.
He said that he would go back to the US soon.
如果宾语从句表示的是客观事实或真理，即使主句是过去时，从句也用一般现在时态。
记忆口诀：真理永不变，一般现在时
Our teacher said that January is the first month of the year.
Scientists have proved that the earth turns around the sun.
He told me that the earth is round.

4 --Could you please tell me______ you will be back
--For two weeks.
5–Could you tell me _______ people celebrate the Dragon Boat Festival in China
--Sure. People usually watch the dragon boat races and eat zongzi.
考向四 宾语从句的语序
宾语从句的语序应为陈述句的语序，即按照主语、谓语的顺序。
1. 陈述句变为宾语从句，语序不变，即仍用陈述语序。
He is an honest boy. The teacher said.
→ The teacher said(that) he was an honest boy.
2. 一般疑问句和特殊疑问句变为宾语从句，语序变为陈述语序。
Does he work hard I wonder. → I wonder if/whether he works hard.
考向五 宾语从句的否定转移和特殊用法
1.宾语从句的否定前置
think , believe , suppose, consider, imagine等动词后的宾语从句如果是否定句，一般要将否定词not转移至主句谓语上，而将从句谓语改为肯定形式。否定前置的前提是：主句主语是第一人称，时态为一般现在时。
I think. + He has no time to play with the girl. → I don’t think he has time to play with the girl.
She thinks. + She can’t arrive here on time. → She thinks she can’t arrive here on time.
3.宾语从句的转化
（1）当主句谓语动词是hope, wish, decide, forget, plan, agree等，且主句与从句主语相同时，从句可简化为不定式结构（动词+to do）。
She agreed that she could help me with my maths. → She agreed to help me with my maths.
（2）当主句谓语动词是know, learn, forget, remember, decide等后面带特殊疑问句转化的宾语，且主句与从句主语相同时，从句可以简化成“疑问词+不定式结构”。
I don't know which sweater I should buy. → I don't know which sweater to buy.
（3）当主句谓语动词是ask, tell, show, teach，宾语从句由代词/副词引导，从句主语与主句主语或间接宾语一致时，从句可简化为“连接代词/副词+不定式”结构。
Could you tell me how I can get to the park → Could you tell me how to get to the park
（4）当主句谓语动词是find, see, watch, hear等感官动词时，从句常简化为“宾语+宾补”结构，宾补为不带to的不定式或V-ing形式。?
She found that the wallet lay/was lying on the ground. → She found the wallet lie/lying on the ground.

My parents took me to Japan when I was little. I lived there for five years. 26 I came back, my Japanese was very good. “Can I do something useful with my Japanese ” I asked myself. Then, one day last spring, I got 27 good opportunity.
Everyone was afraid of SARS, so I stayed at home with 28 to do. My father bought me a Japanese book. “Why don’t you translate it into Chinese It will be better than 29 computer games all day.”
I promised to do 2,000 words each day. But later I found it was hard to keep the promise. One day in May, the weather was beautiful. But I couldn’t go out. Those 2 000 words were still 30 me.
After translating only three pages, I already lost interest in the book.
I looked at it for a long time. But I couldn’t make myself turn the pages. 31 I wished I could just go outside and play football with my friends!
The words 32 by me again and again. I just wanted to give up.
I felt as if two people were fighting 33 my mind. One said, “Don’t give up! Keep working hard, and you’ll do well!” But then the other one said, “Go and play! It will be 34 than translating. Do your work tomorrow.”
I stood up and would turn off the computer.
But then I remembered 35 my parents had told me,“Whatever you do, don’t stop half way.” So I sat down and went on with it.

Growing up, I was a try-hard in school. If I didn’t get straight A’s, I would be so hard on myself. I drove myself into a dark place that I was still recovering 36 .
Last year was my freshman year of college. In my first semester, I drove myself into the ground and got a GPA of 3.8. In my second semester, things stopped 37 (go) my way. I was sick, mentally and emotionally. I got my first C ever. I thought geography had ruined my life, but 38 (actual), maybe that changed my life.
It wasn’t until my sophomore year 39 I realized that I needed help. I always tried to hide my 40 (anxious) but it came to the point where I couldn’t pretend that I was OK anymore. 41 (admit) I needed help was the best thing that I ever did for myself.
Now with all of this being said, I want to make 42 very clear that I still always give 100 percent. But things are different now. I know my limits and I understand 43 (I) more. I no longer have a(an) 44 (health) relationship with school and really I am learning more now than ever before. I am so excited to show the company that hires me everything I have to offer. I am 45 (confidence) that even though I am not a straight-A student, I have more to offer than my grades.

宾语从句是中考必考考点之一，主要考查的是时态及宾语从句的语序，有时也会考查宾语从句的引导词。考查的主要形式是单项填空、完形填空、短文填空和完成句子。阅读理解和书面表达肯定也会考查到宾语从句。因此学生要熟练掌握宾语从句的用法。
