名师讲解：宾语从句的时态
宾语从句的时态
1. 如果主句的时态是一般现在时，宾语从句该用什么时态就用什么时态。即，从句可用所需的任何时态

Please tell us where he is.
Can you tell me how I can get to the railway station?
He says Mary is playing with the cat .
He says Mary often plays with the cat.
He says Mary will play with the cat.
I think he left yesterday morning.
2. 如果主句的时态是一般过去时，宾语从句只能用相应的过去时态（一般过去时，过去进行时，过去将来时，过去完成时）。例如：

He asked if you had written to Peter.
He said that he would go back to the U.S. soon.
He said, “Mary is playing with the cat.” →

3. 如果宾语从句所陈述的是客观真理，其时态常用一般现在时，不受主句时态的限制。例如：
Our teacher said that January is the first month of the year.
Scientists have proved that the earth turns around the sun.
The teacher said, “the moon moves around the sun.”
→ The teacher said that the moon m oves around the sun.
He said, “light travels much faster than sound.”

宾语从句专项练习(含答案)宾语从句：用一个完整句子充当前面某个谓语动词的宾语对象 不论宾语从句由什么引导词引导，也不论主句是陈述句还是疑问句，宾语从句一律用陈述句语序，即“引导词＋主语＋谓语＋其他”结构。判断正误： We don't know when will they arrive. ( ) We don't know when they will arrive. ( ) Could you tell me who is he waiting for? ( ) Could you tell me who he is waiting for? ( ) 注意：特殊疑问词作主语时，如果语序本来就是“主语＋谓语”结构，则语序不再变化。如： Please tell me. Who will give us a talk this afternoon？(合并为一句) →Please tell me _____________us a talk this afternoon. 宾语从句在时态上应遵循时态呼应原则 在宾语从句中，谓语动词时态要受到主句谓语动词时态的制约，一般要遵循以下三条原则： 1．主句是祈使句或主句中的谓语动词是一般现在时或一般将来，则宾语从句根据实际选用时态。如： Will you tell us which places you visited during the vacation? 2．如果主句中的谓语动词是一般过去时，则宾语从句需要使用表示过去的某种时态。如： I knew she had cleaned the classroom already. 3．宾语从句所表达的是客观事实、真理、自然现象、名言、警句、谚语等，多用一般现在时。如： He said time is money. Our teacher told us that light travels much faster than sound. 宾语从句的“否定转移” 当主句的谓语动词为think, believe等词，且主语为第一人称时，从句中的否定词not应转移到主句谓语动词。如： 合并为一句 宾语从句的简化结构 由特殊疑问词引导的宾语从句通常可以简化成“特殊疑问词＋不定式”结构，此时主从复合句也就变成了简 单句，但简化必须符合以下两种条件： 1．简单句的疑问词为原宾语从句的引导词； 2．原从句的主语应与主句的主语或间接宾语一致。 I don't know what I should do next.(改为简单句) →I don't know ____________________. 含有宾语从句的复合句的反意疑问句 1．陈述部分是“I/We think (know, believe, suppose, consider)＋that从句”或者是“I'm/We're sure that; I'm/We're afraid that; I/We hope that; It seems that”时，附加疑问部分的主语应和从句一致，但需注意否定前移的情况。如： I don't think he is right, ____________？ I'm sure that you know him well, ______________？ 2．如果主语是其他人称，附加疑问部分的主语和主句一致。如： Your father believed you could succeed, ______________？ Kate doesn't know if Jim is a good singer, ______________？ 宾语从句中人称的变化 注意宾语从句中人称代词的正确使用。一般遵循“一随主，二随宾，第三人称不更新”的原则。 解题技巧：
宾语从句综合分析（时态、语序、引导词，每部分均含讲解、练习及答案）目录：（一）宾语从句基础讲解 （二）宾语从句的转化 （三）典例讲解 因此，简单地来说，整个句子担当宾语成分，那么这样的句子就叫宾语从句。 （一）宾语从句基础讲解 1. 概念: 在句中担当宾语的从句叫宾语从句，宾语从句可作谓语动词的宾语，也可做介词的宾语。 E.g. He said he was good at drawing. (动词宾语) He asks him how long Mike has been down . (动词宾语)
Miss Zhang is angry at what you said. (介词宾语) 2. 连接词 (1) 陈述句转化成宾语从句时，引导词用that,口语中常常省略。 e.g, She told me (that) she would like to go with us. (2) 以 whether 或if 引导的宾语从句, 主要用来引导一般疑问句意思或选择疑问句意思的宾语从句，从句同样是陈述语序 E.g. I wonder if /whether u have told the new to Li Lei . (3) 特殊疑问句转化成宾语从句时，引导词用特殊疑问词；引导词后要用陈述句语序。 E.g. Could you tell me what's the matter/wrong with you? 特殊情况：当do you think后接特殊疑问句转化成宾语从句时，句式结构应为引导词＋do you think＋陈述句语序。
3. 宾语从句时态 a. 当主句是一般现在时，一般将来时或祈使句时，从句不受主句的限制，根据自身的需要选用相应的时态。例如： Do you know（if/whether he has seen the film）? b. 当主句是一般过去时，从句要用过去时的相应时态。例如： I didn't know （if/whether he had seen the film.） 注意：当主句是一般过去时，而从句表示的是客观真理，自然现象，科学原理，格言等，从句仍然要用一般现在时。 例如： He said （that the earth moves round the sun.） The teacher told us （that light travels much faster than sound.） 4. 人称的变化和标点的使用 a. 从句的主语如果是第一人称，变为宾语从句则与主句的主语一致；如果是第二人称，则与主句的宾语一致；如果是第三人称，不用变化。 (一主二宾三不变) “May I use your knife？”He asked me. →He asked me if he might use my knife. “Do you know her telephone number?” He asked me. →He asked me if I know her telephone number. b. 宾语从句的标点均由主句决定。 主句是陈述句，用句号；主句是疑问句，用问号。如： Who will give us a talk? I don’t know. → I don’t know who will give us a talk.
1.宾语从句： 1.主句若是一般现在时，从句根据实际情况用适当时态。He says (that) he will have a walk soon. The teacher asks who is the cleverest in the school. I want to know who came here late this morning. 2.主句若是一般过去时，从句也要用过去时。 He wondered if I would come. She told me that her son had got well. She said that she liked watching TV. We thought Jim was wrong. 3.无论主句是何时态，从句若表客观真理，要用一般现 在时。 Mr. Li said the moon is smaller than the earth. 4宾语从句无论有何引导词，都要用陈述句语序。 Could you tell me when you will get back to Wuhan?（不是will you） Do you know which sweater she is wearing? (不是is she)
2.状语从句：1主句若是一般将来时、祈使句或含不表过 去的情态动词等，则if(如果), unless(除非)，when(当…的时候), as soon as(一…就…），before, after, until, till, as(当…的时候)所引导的状语从句用一般现在时。 You may take a rest when you finish doing your work. I will call you up if I leave for Shanghai next week. Wait for your brother at the bus station until he arrives. 2而主句若是一般过去时，从句也要用过去时，如： I would give the money to the charity if I had a million dollars. When he got to the park, his classmates had left. My son ran towards me as soon as he saw me on the street. 3.定语从句：关系代词who只指人，which只指物。that 既可指人又可指物。whose 后必须跟有名词，既指人，也可 指物。关系词作主语时，不可省略，作宾语时可省略。whom 只指人，只作宾语。关系副词where指“在那里”，when指“在那时”。 She is a girl who/that is beautiful and kind-hearted.
初中英语宾语从句知识点讲解 在句子中起宾语作用的从句叫做宾语从句。学习宾语从句要抓住三要素：引导词、语序和时态。 一、.引导词 1.从句为陈述句，常选择引导词that，that引导宾语从句无意义，不充当句子成分常省略。例句：He told us (that) they would help us through the whole work. 2.从句为一般疑问句，常选择引导词if或whether，表示“是否”。在 whether … or not 结构中不能用 if 替换。例句：I don’t know if there will be a bus any more. 3. 从句为特殊疑问句，常选择what,when,where,which,who,how等的疑问代词、副词作引导词。例句：He didn’t tell me when we should meet again. 二、判断时态情况： 1.主句是一般现在时，从句可以为各种时态。 2.主句是一般过去时，从句要用相应过去时态。 注意：从句描绘客观事实、真理、自然现象等，从句时态不受主句时态限制，仍用一般现在时。 例句：He answered that he was listening to me. Father told me that practice makes perfect . 三、宾语从句的语序要用陈述句语序 陈述句语序，就是主语在前，谓语动词在后。 错误: He is wondering when can he finish this difficult job. 正确: He is wondering when he can finish this difficult job. 注意：宾语从句的否定转移
主从句的时态问题
从句和主句中谓语动词的时态 在复合句中，主句和从句的谓语动词时态一般遵循以下的规律： 一① 在以下三种主语从句中，主语从句的谓语动词要用“should+动词 原形”， should可省略。 (1)It is+形容词+that…句型。常见的形容词有important, necessary, natural, funny, strange, surprising, astonishing(令人惊讶的)等。 (2) It is +名词+that…句型。常见的名词有pity, shame, advice, suggestion, proposal(提议，建议)， requirement, request, desire, order 等。 (3) It is+动词的过去分词+ that…句型。常见的动词有advise, order, propose, request, suggest, demand, require等。 ②在insist(坚持)， urge (催促)， order(命令)， command(命令)，suggest(建议)，advise(建议)，recommend(建议，推荐)， request(请求，要 求)， demand(要求)，require(要求，需要)等动词后的宾语从句中，谓语动词用“should+动词原形”， should可省略。 ③ 在含有advice, order, demand, proposal(提议)， requirement, suggestion等名词的表语从句、同位语从句中，谓语动词用“should+动词原形”，should可省略。 ④在一些表示惊讶、意志等感情色彩的名词性从句中，谓语动词用“should+动词原形”或“should +have done”，译为“竟然，居然”。例如： I am surprised /shocked that you should speak in such a way。 I find it astonishing that he should be so rude to his mum。 It is strange /surprising that she should not have been invited。 I am glad that your story should have won the first prize。
时态复习资料 一般现在时(经常,反复,爱好,特点,条件,真理) do; does am;is;are done 一般过去时(过去发生的事,不强调现在的结果) did; -ed was;were done 一般将来时(将要发生的事) will do will be done 现在进行时(现在正在发生的事) am;is;are doing am;is;are being done 过去进行时(当时正在发生的事) was;were doing was;were being done 现在完成时(过去发生的事,强调现在的结果) have;has done have;has been done 过去完成时(过去完成的事；过去以前发生的事) had done had been done 过去将来时(过去将要发生的事) would do would be done 一般现在时 1.概念：经常、反复发生的动作或行为及现在的某种状况。 2.关键词：always, usually, often, sometimes, every week (day, year, month…), once a week, on Sundays, 3.基本结构：动词原形（如主语为第三人称单数，动词上要改为第三人称单数形式） 4.否定形式：am/is/are+not;此时态的谓语动词若为行为动词，则在其前加don't,如主语为第三人称单数，则用doesn't，同时还原行为动词。 5.一般疑问句：把be动词放于句首；用助动词do提问，如主语为第三人称单数，则用does，同时，还原行为动词。 二、一般过去时 1.概念：过去某个时间里发生的动作或状态；过去习惯性、经常性的动作、行为。

初中英语6大词性+8大时态+3大从句总结 语法知识是在掌握一定量的单词和短语的基础上才能获得的。因此，单词的 形态变化是语法学习的基础之基础。而八种基本时态和含有不复杂的状语从句、定语从句及宾语从句的复合句是初中生学习的重点也是语法学习的难点。 总之，语法部分是英语学习的重点和难点。语法知识掌握得好，将大大加快英语学习的进程。本文归纳了六大词性、八种基本时态以及初中生需要掌握三种基本从句。希望对广大中学生们有所帮助。 初中英语六大词性 名词 1.名词的可数与不可数 可数名词指表示的人或事物可以用数来计量，它有单数与复数两种形式。不可数名词指所表示的事物不能用数来计量。物质名词与抽象名词一般无法用数目，来统计，都成为不可数名词。 不可数名词前一般不能用冠词a、an来表示数量，没有复数形式。要表示“一个……”这一概念，就须加a piece of这一类短语。要注意许多名词在汉语里看来是可数名词，在英语里却不可数。如：chalk，paper，bread，rice，grass，news等。 2.名词复数的规则变化 A.一般情况下加-s。 B.以s, x, ch, sh, 结尾的加-es C.以辅音字母加y结尾的改y为i再加-es D.以f，fe结尾的，去掉f或fe，变成v再加-es 3.名词的所有格 A. 单数名词词尾加’s，复数名词词尾若没有s，也要加’s。 如：the worker's bike，the Children’ s ball B. 表示几个人共有一样东西，只需在最后一个人的名字后加’ s若表示各自所有，则需在各个名字后’ s。 如：This is Lucy and Licy’ s room.These are Kate's and jack’ s rooms.
英语宾语从句宾语从句的时态问题 1）当主句的谓语动词是一般现在时时，其宾语从句的时态可以是任何适当的时态。所以，宾语从句的时态应根据实际情况而定。eg. 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嵋山。 （从句是现在完成时） 2）当主句的谓语动词的时态是一般过去时的时候，其宾语从句的时态一般要用任一适当的过去时态。eg. 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） 但是当宾语从句是表达客观真理和规律的句子时，其时态仍旧用一般现在时。eg. The teacher told us(that) nothing is difficult if we put our hearts 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. 他说光比声音传播得快。

一般情况下宾语从句的时态必须和主句的时态保持一致： 一、如果主句的谓语动词是一般现在时或一般将来时，宾语从句中的谓语动词可根据意义的需要，使用任何一种时态。如： 1） Could you tell me when you will come again? 你能告诉我你什么时候再来吗？ 2） I don't know if he arrived yesterday. 我不知道他是否昨天到了。 3） Could you tell me what you were doing at eight last night? 你能告诉我你昨晚八点在干什么？ 二、如果主句的谓语动词为一般过去时，从句应用相应的过去时态。 1. 如果主句中的谓语动词所表示的动作与从句的动作同时发生，则从句应用过去进行时或一般过去时。如： 1) She said that she was working on the Internet. 她说她在上网。 2) He told me that he knew the computer technology very well. 他对我说他精通电脑技术。 2. 如果从句的动作发生在主句的动作之前，则从句应用过去完成时。如： 1） He didn't know what they had come here for. 他不知道他们到这里来的目的。 3. 如果从句的动作发生在主句的动作之后，则从句应用过去将来时。如： 1） Jim told me he would spend his holidays in the south. 吉姆告诉我他将到南方度假。 使用宾语从句的时态还应注意下列特殊情况： 一、如果宾语从句中有明确表示过去的时间状语，不论主句用什么时态，从句一律用过去时。如： 1） She said she came to work here in 1998. 她说她是1998年来这里工作的。 2） The teacher told us that the war broke out in the winter of 1923. 老师告诉我们那场战争爆发于1923年的冬天。 二、如果宾语从句表示客观真理、科学原理、自然现象、现阶段存在的客观事实、现在经常性或习惯性的动作、谚语、格言等，不论主句用何种时态，从句一律用一般现在时。如：1） Our teacher told us that light travels much faster than sound. 我们老师对我们说光比声音传播要快得多。 2） The mother told his son that two and three is five. 母亲告诉孩子二加三等于五。 3） We all knew that a friend in need is a friend indeed. 我们都知道，患难之交才是真朋友。4） He told me that his father is an English teacher. 他告诉我他父亲是名英语老师。
