名词性从句、定语从句、状语从句时态问题

一、名词性从句（一）在宾语从句中主句和从句之间的时态的一致关系,通常由主句谓语的时态决定从句谓语的时态.⒈若主句谓语动词是现在时或将来时,如：一般现在时,现在完成时,一般将来时,将来完成时等,从句可以根据需要使用任何时态.如:He says that he is doing well in his lessons.you will miss a lot of lessons.the boy is lazy.XiaoWang was late for school yesterday.Jim has been back for two days.⒉若主句谓语动词是过去时态(一般过去时,过去进行时,过去完成时,过去将来时,过去将来完成时),从句谓语动词也必须是过去时态.如:He said he enjoyed himself last Sunday.he hadn’t bought any present.the would come back the next day.he was doing his homework·⒊当从句表示客观事物或真理,或人们已经公认的道理时,其时态不受主句谓语动词的时态的影响.即使主句谓语动词使用了过去时的某种时态,从句的时态仍然是现在的某种时态.1)The teacher said the earth goes around the sun。

2)He said the sun rises in the east.3)His father said he gets up at six o'clock every morning.4)He told me the light travels faster than the sound.⒋当从句表示并未出现或尚未实现的愿望时,必须用过去时态.⒌（可包含在1/2中）有些形容词后面可跟有从句,这种从句一般可看作宾语从句,其谓语也应与主句谓语的时态保持一致.可跟这种宾语从句的形容词有：afraid,glad,sure,confident,sorry, certain,conscious,aware等.一致的原则与宾语从句相同.例如：I'm confident that I'll pass the exam.我有信心通过考试.He was lucky that he wasn't killed.他很幸运没有被杀死.（二）在主语从句,表语从句和同位语从句中,主句和从句之间的时态一致关系所遵守的法则和宾语从句相同.例如：It appears that some little trouble was caused by a woman,whose name has not been ascertained.看来这件小小的麻烦是由一个至今尚不清楚其姓名的女人所引起的.It was known long ago that Professor Einstein played a key role in the development of the theory of relativity.人们早已知道,爱因斯坦教授对相对论的发展起了关键作用.It was proved centuries ago that the speed of light is186,000miles a second.几世纪前就证实了光的速度为每秒186,000英里.The fact[that man would soon be able to visit the moon]built up new scientific interest in earth's nearest neighbor.人类不久可以游览月球的事实,引起了对地球最近邻居的新的科学兴趣.二、定语从句与主句的时态一致关系定语从句的时态不受影响意思就是定语从句的时态是根据事物真实发生的情景决定不受主句影响,因为定语从句的作用只是在修饰句子中的名词之类的,和句子本身的时态没有关系.比如：He is a man whose telephone was stolen.他是那个手机被偷的那个人.主句一般现在时,从句过去时,因为手机真实被偷是在过去发生.I went to the apartment in which Mary lives in.我去过Mary现在住的房子.主句过去式,从句一般现在时,因为我去过的那个房子,Mary确实现在在住.⒈若定语从句的谓语表示的动作和主句谓语表示的动作同时发生,则要求使用同样的时态.The original manuscript of"The Theory of Relativity"was written by Einstein whowas employee in a patent office.“相对论”的原稿是由当时在一家专利办公室工作的爱因斯坦写的.⒉主句与定语从句的谓语表示的动作如果不是同时发生,时态则不要求一致.例如：Have you seen the new golf clubs that Mr.Stevens gave Bill?你看过史蒂文斯先生给比尔的那些新高尔夫球棒了吗?I painted several pictures that are now on show in the museums.我画了几张画,现在正在博物馆里展出.三、状语从句与主句的时态状语从句中的时态对应类型。

英语三大从句语法讲解

英语三大从句在英语中,主要有三大从句,即名词性从句包括主语从句,宾语从句,表语从句,同位语从句、形容词性从句即定语从句、副词性从句即状语从句,包括时间、条件、结果、目的、原因、让步、地点、方式等;定语从句一、关系代词引导的定语从句关系代词代替前面的先行词,并且在定语从句中充当句子成分,可以作主语、宾语、定语等;常见的关系代词有：who, that, which;它们的主格、宾格和所有格如下表所示：一关系代词who, whom和 whose的用法who代替人,是主格,在定语从句中作主语;An architect is a person who designs buildings. 建筑师是设计房屋的人;whom代替人,是宾格,在定语从句作宾语,在非正式英语常可省略;Do you know the gentleman whom we met in the school library yesterday 昨天我们在学校图书馆里遇到的那位先生你认识吗whose一般代替人,有时亦可代替物,是所有格,在定语从句作定语;The girl student whose father is a senior engineer used to study abroad. 其父是一位高级工程师的那个女学生过去在国外留学;Do you know the name of the hotel whose window we can see here 我们这儿能看到窗户的那个宾馆叫什么名字,你知道吗关系代词whose指代先行词hotel,正式用法应该用of which;whose window=the window of which,意思是：the window of the hotel;二关系代词which的用法which代替物,在定语从句作主语或宾语,作宾语时还可省略;I do not like stories which have unhappy endings.我不喜欢有不幸结局的小说;which可以换成that三关系代词that的用法that既可指人又可指物,在当代英语中大多指物,在定语从句作主语或宾语,作宾语时还可省略;： Is she the girl that sells newspapers她是卖报纸的那个女孩吗that可以换成whoWhere is the ice-cream that was in the fridge放在冰箱的冰激凌哪儿去了that可以换成whichIs this the book that you want to buy这是你要买的那本书吗 that可以换成which,在定语从句作宾语,还可以省略二、关系副词引导的定语从句常用的关系副词只有三个：when, where, why,在定语从句中充当时间、地点和原因状语;一关系副词when的用法关系副词when代替的先行词表示的是时间,when在定语从句作时间状语;In Beijing July and August are the months when it rains very often.北京的七月和八月是常下雨的月份;when先行词是months二关系副词where的用法关系副词where代替的先行词表示的是地点,where在定语从句作地点状语;During the Spring Festival I went back to the town where I was brought up.春节期间,我回到了生我养我的家乡;where的先行词是town三关系副词why的用法关系副词why代替的先行词表示的是原因,why在定语从句作原因状语;The reason why I am phoning you is to ask you whether you have got my email.我打电话给你的原因是想问问你是否收到了我的电子邮件;why先行词是reason, 当代英语里why可以用that替代,这时关系代词that就变成了表示原因的关系副词,还可以将why省略三、特殊关系代词as引导的定语从句一在固定搭配as…as, so…as, such…as, the same…as中,as引导定语从句You may take as many books as you want.你想要拿多少书就拿多少;第一个as是副词,修饰many的；第二个as才是关系代词,代替先行词books,在定语从句中作宾语二独立于主句之外,as引导定语从句As we know/ As is known to us, the earth turns around the sun. 正如我们所知,地球围绕太阳旋转;As we know和 As is known to us均为定语从句,as分别作宾语和主语,替代后面的主句;Taiwan is, as you know, an inseparable part of China.你知道,台湾是中国不可分割的一部分;关系代词as指代整个主句,在定语从句中作宾语;四、关系代词who, which与that的区别一关系代词who与that的区别1. 当关系代词用作主语时,多用主格who;He who loses hope loses all.失去希望的人就失去一切;先行词为代词he, they, any, all, one等时,多用whoI met Alice, who told me that she was learning Chinese.我遇见艾丽斯,她告诉我她在学汉语;在非限制性定语从句中,用who2. 当关系代词用作介词后的宾语时,用宾格whom,不用that;The man to whom our headmaster talked just now is our English teacher.我们校长刚才与他谈话的那个人是我们的英语老师;介词与关系代词紧密相连时,只能用宾格whom,不可用主格who注意：介词与关系代词不是紧密相连时,或者说介词放在句子后面时,这时可以用主格who,也可用that,还可以省略关系代词;因此,上面的这句话还可以有如下四种说法：1 The man whom our headmaster talked to just now is our English teacher.2 The man who our headmaster talked to just now is our English teacher.3 The man that our headmaster talked to just now is our English teacher.4 The man our headmaster talked to just now is our English teacher.3. 当关系代词泛指人时,多用that;He is a man that is never afraid of failure.他是个从不怕失败的人;that用来泛指人4. 当关系代词出现在who开头的疑问句时,应用that;例如：Who is the girl that is talking to Tom in English用英语同汤姆交谈的那个女孩是谁避免重复使用who,以免造成误解或语义含混不清二关系代词which与that的区别1. 当先行词为all, much, little以及不定代词anything, something, everything等时,关系代词多用that;All that glitters is not gold. 闪闪发光物,未必尽黄金;She told me everything that she knew. 她把她所知道的一切都告诉了我;2. 当先行词的前面有形容词最高级、序数词或限定词the only, the very, all, every, any, no 等时,关系代词一般都用that;This is the best novel that I have ever read. 这是我读过的最好的一部小说;He is the only person that has been invited to the ball. 他是惟一应邀参加舞会的人;3. 当关系代词出现在which开头的疑问句时,应用that;Which was the hotel that was recommended to the foreign guest 哪一个是推荐给外宾的宾馆这里使用that很明显是为了避免重复which4. 在非限制性定语从句中,关系代词一般只用which;Beijing, which is the capital of the People’s Republic of China, will host the 2008 Olympic Games. 北京是中华人民共和国的首都,将主办2008年奥运会;5. 介词后的关系代词用which,而不用that;She has collected 600 stamps, 60% of which are German stamps. 她收集了600张邮票,其中60％是德国邮票;五、定语从句的位置如前所述,定语从句一般总是直接置于所修饰的名词或代词之后;有时候,定语从句与先行词之间插入了其他的短语,这样它们被分隔了,这种情况下的定语从句被称作隔离定语从句;There was a girl upstairs who was shouting and crying, obviously mad.楼上有一个女孩,大喊大叫;很明显,她疯了;定语从句who was shouting and crying修饰the girl,被upstairs所隔开A new master will come tomorrow who will teach you German.明天要来一位新老师教你们德语了;定语从句置于句末以示强调名词性从句宾语从句一、引导词1由that 引导的陈述句性的宾语从句,在很多动词如say, think, wish , hope, see, believe, agree, expect, hear , feel等动词后;连词that只起连接作用,在从句中不做句子的成分,也无词汇意义,在口语中常被省略;如：I told him that he was wrong.在think, believe, suppose, expect等动词引起的宾语从句中,有时谓语尽管是否定意义,却不用否定形式,而将think 等动词变为否定形式;见语法：否定转移如：I don’t think you are right. 我认为你做的不对在许多带有复合宾语的句子中,that引导的宾语从句经常移到句子的后面,而用it做形式宾语;We think it wrong that he told a lie to everyone 我认为他向每一个人撒谎是错误的2 由连词if、 whether 引导的表示“是否…”的宾语从句;Whether, if 在从句中不做句子的成分,一般情况下,whether和if 可以替换;I don’t know if/whether he will come tomorrow.在介词后面的宾语从句中不用if引导Everything depends on whether we have enough money.宾语从句中有or not时不用if引导.I don’t know whether the movie star will come or not.和不定式连用作宾语时不用if引导Whether to go there or not hasn’t been decided.3由wh-引导的宾语从句;连接代词who, whom, whose, what, which和连接副词when, where, why, how 等连接的宾语从句,它们在句中即有连接从句的作用,又在句中充当句子的成分;Do you know which film they are talking about which做定语I don’t know where he lives. where 做地点状语二、宾语从句的语序,宾语从句的语序必须是陈述语序,既连接词+主语+谓语+其他成分 I believe that they will come soon.特例：有下列常见的问句,作为从句出现,是“不改变语句顺序”的;1. What's the matter2. What's wrong3. What's up4. What's the problem5. What's your trouble三、宾语从句的时态;宾语从句的时态受主句的限制,即：主句是一般现在时态,从句根据实际情况而定；主句是一般过去时态,从句用相应的过去的时态;如果从句的动作发生在主句之前,则从句要用过去完成时态;1 She says that she is a student.→ She said that she was a student.2She says that she will fly to Japan in a week. → She said that she would fly to Japan in a week.3She says that she has finished her homework alre ady. → She said that she had finished her homework already.1如果宾语从句说的是客观真理、自然现象或事实时,这时宾语从句要用一般现在时态;The teacher said that the earth goes round the sun.2Could you tell me…是用来征询对方的意见,语气委婉,并不表示过去;Could you tell me when we will visit the History Museum注意事项：3由陈述句变成宾语从句时,要注意人称的变化;She said: “I have been to England before.” → She said that she had been to England before. She asked me: “Do you like maths” → She asked me if I liked maths.4宾语从句与简单句的交换;由连接代词和连接副词引导的宾语从句,如果宾语从句的主语和主句的主语是同一个人时,可以用“疑问词+不定式”做宾语的简单句结构;I don’t know what I should do next. → I don’t know what to do next.DO SOME EXERCISES:you see AA. what he’s readingB. what is he readingC. what does he readD. he reads what2.

Why is our Chinese team be able to beat Korea同位语从句一一般来说,在主从复合句中,用作同位语的从句叫同位语从句;它通常跟在某些名词之后,用以说明或解释该名词表示的具体内容;可以跟同位语从句的名词通常有：advice, decision, fact, hope, idea, information, message, news, promise, proposal, reply, report, suggestion, word消息,problem, question, doubt, thought等;eg: They were delighted at the news that their team had won.当听到他们队获胜的消息时,他们欣喜若狂;有时同位语从句可以不紧跟在被说明的名词后面,而被别的词隔开; 如：The thought came to him that Tom might have returned the book.他突然想起汤姆可能已经还了书了;二引导词1. The news that Mr. Li will be our new English teacher is true.2. He hasn’t made the decision whether he will go there.3. The question who should do the work is being discussed at the meeting.4. I have no idea what the boy is doing in the next room now.5. We haven’t yet settled the question where we are going to spend our summer vacation this year.6. I have no idea how I can get to the railway station.7. I have no idea when he will be back．小结：① that引导同位语从句时无词义,也不充当任何成分,但通常不可以省略,如句1；② whether引导同位语从句时意为“是否”,通常不能用if来代替, 如句2;③ 连接代词who, what等可以引导同位语从句,如句3, 4；④ 连接副词where, how, when等可以引导同位语从句, 如句5,6,7;三 that 引导的同位语从句和定语从句① 意义不同：同位语从句用来进一步说明前面名词的内容；而定语从句用来修饰、限定前面的先行词;试比较：1. The news that our team has won the final match is encouraging.2. The news that you told us is really encouraging.② that的功能不同：that引导同位语从句时是一个纯连词,不充当任何成分；而引导定语从句时,不仅起连接作用,而且还指代先行词并在从句中充当主语、宾语等成分;试比较：1. Dad made a promise that he would buy me a CD player if I passed the English test.2. Dad made a promise that excited all his children.③ 可否省略：that在引导同位语从句时,通常不可省略;在引导定语从句时,若在从句中作宾语,通常可以省略,若作主语则不可以省略;DO SOME EXERCISES:I. 请用适当的词填空,使下列句子意思完整;1.

One of the men heldthe opinion when what the book said was right.表语从句表语从句只能置于主句之后,而主句的动词只能是连系动词;名词性从句在be等系动词后作表语时被称为表语从句The problem is how we can get the things we need.问题是我们怎样能弄到我们需要的东西;how 在表语从句中充当方式状语The scissors are not what I need. 这把剪刀不是我所需要的;what 在表语从句中充当宾语What I told him was that I would find him a good play. 我告诉他的是我会给他找个好剧本;what 在主语从句中作直接宾语, that作为表语从句的引导词在该表语从句中不充当句子成分, 不能省略That is what I want to tell you.那就是我想要对你讲的;what在表语从句中充当直接宾语That is why she failed to pass the exam. 那就是她考试不及格的原因;why 在表语从句中充当原因状语“That is why...”是常用句型, 意为“这就是……的原因/因此……”, 其中why引导的名词性从句在句中作表语, 该句型通常用于针对前面已经说明过的原因进行总结下面是两个与“That is why...”形式相似的结构, 它们与“That is why...”结构之间的关系要能够辨析清楚：1“That is why...”与“That is the reason why...”同义, 只不过从语法结构上讲, “That is the reason why...”中why引导的是—个定语从句, 将其中的the reason去掉则与“That is why...”结构一样 That is the reason why I cannot agree.2“That is because...”句型中从属连词because引导的名词性从句在此作表语, 这也是个常用句型, 意为“这就是为什么……/因为……”;“That is because...”与“That is why...”之间的不同在于“That is because...”指原因或理由, “That is why...”则指由于各种原因所造成的后果He did not see the film last night. That is because he had to help his little sister with her homework.昨天晚上他没有去看电影, 那是因为他得帮助他的妹妹做作业;第一句话说明结果, 第二句话说明原因He had seen the film before. That is why he did not see it last night.他以前曾看过那部电影, 因此他昨天晚上没有去看;第一句话说明原因, 第二句话说明结果考题1The traditional view is ____ we sleep because our brain is “programmed” to make us do so. 2007上海A. whenB. whyC. whetherD. that考题2You are saying that everyone should be equal, and this is ____ I disagree. 2004A. whyB. whereC. whatD. how考题3— I drove to Zhuhai for the air show last week.— Is that ____ you had a few days off 1999A. whyB. whenC. whatD. where考题4____ made the school proud was ____ more than 90% of the students had been admitted to key universities. 2003上海春A.

英语中的从句解析

从句是相对于主句而言的，即它是从属于某一个主句，而不能单独作一个句子。

在英语中，主要有三大从句，即名词性从句（包括主语从句，宾语从句，表语从句，同位语从句）、形容词性从句（即定语从句）、副词性从句（即状语从句,包括时间、条件、结果、目的、原因、让步、地点、方式等）。

主语从句用作主语，如：That the earth is round is true. 地球为圆的是真实的。

宾语从句用作宾语。

如：Do you know where he lives?表语从句用作表语，如：My opinion is that you should not go alone. 我的意见是你不应单独前往。

同位语从句用于解释说明前面的名词。

如：The fact that the earth is round is true. 地球是圆的的事实是真实的。

（that从句用于解释说明the fact）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.状语从句相当于一个副词，如：When it rains, I usually go to school by bus. 天下雨时，我通常坐公共汽车上学。

（时间状语）If he comes tomorrow, you will see him. 如果他明天来，你就可以看见他。

（if 引导的条件状语从句，其结构为：if +状语从句，＋主句）。

要注意在状语从句中有一个规则是“主将从现”，即主句是将来时，则从句要用一般现在时表示将来。

主句和从句的划分方法是相同的。

句子的成分从谓语动词处来划分比较容易。

谓语动词前面的部分是主语，后面常接宾语，修饰谓语动词的是状语，修饰主语、宾语的是定语，若谓语是系动词，则系动词后的部分是表语。

如：I am a teacher. 其中，I 是主语，am是谓语，a teacher 是表语。

深入分析中文中的五种主要从句类型

深入分析中文中的五种主要从句类型作为一种复杂而丰富的语言，中文中的从句在表达上起到了至关重要的作用。

从句是由一个主句和一个或多个从句组成的句子结构，用于提供更多的信息、解释或补充主句的内容。

在中文中，有五种主要的从句类型，分别是名词性从句、定语从句、状语从句、主语从句和宾语从句。

下面将对这五种从句类型进行深入分析。

一、名词性从句名词性从句在句子中充当名词的角色，可以作为主语、宾语、表语或同位语。

昨天晚上，我看到了一颗流星。

2. 原因状语从句：因为下雨，所以比赛取消了。
