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。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。例如：
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。例如：
Do you know who (whom) they are waiting foe?
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”。例如：
I want to know if (whether) he lives there.
He asked me whether (if) I could help him.
二. 宾语从句的语序
宾语从句的语序应为陈述句的语序。例如：
I hear (that) physics isn’t easy.
I think (that) you will like this school soon.
Can you tell me how I can get to zoo?
Please tell me when we’ll have the meeting.
三. 宾语从句的时态
1. 如果主句的时态是一般现在时，宾语从句该用什麽时态就用什麽时态。
如：
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?
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 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 U.S. soon.
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。例如：
Our teacher said that January is the first month of the year.
Scientists have proved that the earth turns around the sun.
【中考范例】

A. what he is B. if he lives here
C. where he comes from D. which country is he from
【解析】答案: C。该题考查的是宾语从句的语序。按照他们谈论的话题可知：他们说的是某人是哪里人。A和B可以排除掉。D的语序不对，只有C正确。
动词的语态
动词的语态---表示谓语与主语之间的关系的动词形式叫做语态，分为主动语态和被动语态。
主动语态表示主语是动作的执行者,被动语态表示主语是动作的承受者
一、被动语态
结构:1.行为动词的被动语态: 助动词be + 及物动词的过去分词.
be有人称.时态.数的变化,其变化规则与be作为连系动词时完全一样.
一般现在时 am/is/are+及物动词的过去分词 一般过去时 was/were +及物动词的过去分词
一般将来时 will +be +及物动词的过去分词 现在完成时 have/has+been+及物动词的过去分词
2.情态动词的被动语态: 情态动词 + be +及物动词的过去分词
否定式:是在助动词 be 或情态动词后加not构成
疑问式:是把上述助动词或情态动词提到主语之前,句尾加问号构成.
用法: 1.不知道动作的执行者是谁,或没有必要或不想指出谁是动作的执行者.
eg. The window was broken yesterday. Is English taught in your school? 2.强调或突出动作的承受者,此时如想同时指出动作的执行者,可用“by +动作执行者(宾格)来表示.
eg.The red dress was made by her mother. The letter must be written by me.
注 意点： 1.只有及物动词能构成被动语态, 不及物动词不能构成被动语态.
2.某些不及物动词与介词.副词搭配构成短语动词,带有宾语时,则有了动作的承受者,这时应把它们看作一个整体,变为被动语态,不能丢掉其中的介词,常用的有look after,take care of,cut down, laugh at,talk about,turn on等 eg.Catherine always takes care of the little girl.→The little girl is always taken care of by Carherine.
3.有些动词短语本身即是被动语态的形式, 不要再加by 短语,常用的有
be covered with be surprised at be interested in be worried about be made of/from be known to
4.某些动词形式是主动语态,但含有被动的意思. eg. This dictionary sells well.
This kind of car drives fast. The woolen sweater costs $ 88.
5.主动语态与被动语态的相互变化关系
主动句: 主语 + 谓语 + 宾语(动作执行者) (动作承受者)
被动句: 主语 +谓语动词的被动形式+ by + 动作执行者 (动作承受者)
1）主动句如何变为被动句
a.找到动作的承受者(常为主动句的宾语)作被动句的主语.b.找到谓语变为be + 过去分词的结构.
c.找到动作的执行者(常为主动句的主语)作 by 的宾语.若不必指出动作的执行者,可省去 by 短语. d.确定be动词的时态.数. 例如: She makes the beautiful kites.
The beautiful kites are made by her. (被动句)
2）被动句如何变为主动句. a.找到动作的执行者(常为被动句的宾语)作主动句的主语.
b.找到be+过去分词结构还原为及物动词原形.
c.找到动作的承受者(常为被动句的主语)作主动句的宾语.
d.确定及物动词的时态.数(注意)在以上转换中,代词作主语用主格, 代词作宾语用宾格.
6.主动语态中有些动词如:make,see,listen, watch,feel后常跟不带to的动词不定式作宾语补足语,变为被动语态要带上to
He made the boy work for him. →The boy was made to work for him.
7.主动语态中若有双宾语,变为被动语态时, 通常把指人的间接宾语变为被动语态的主语. His uncle gave him a dictionary yesterday.→He was given a dictionary by his uncle yesterday.
G:现在完成时枣表示到目前为止已经完成，并对现在留下某种后果和影响的动作。
结构：助动词have/has + 动词的过去分词
用法:
1.表示过去发生的某一动作对现在造成的影响或结果,常与一些时间状语,如:already, yet, ever, never, just, before, once,twice等连用,也可以和包括现在在内的时间状语,如these days,today,this year,so far等连用.eg.I have already posted the letter. (信已经不在我这儿了)
2.表示过去发生的动作或存在的状态,一直持续到现在,也许还将继续下去,可以和表示从过去某一时刻延续到现在的一段时间的状语连用,即for +时间段,since+时间点/从句, in the last ten years等,谓语只可用延续性动词.
解析： 1.英语动词根据词义可分为两种,一种是延续性的,一种是终止性的,终止性动词(也可称为非延续性动词,瞬间动词,或点动词),如begin,start,die,buy,leave, come等,表示动作的发生与结束于一瞬间完成,不能再延续,所以它的现在完成时不能和表示延续的时间状语连用,即不能与表示一段时间的状语,for+时间段, since+时间点/从句连用,也不能用在how long引导的特殊疑问句中.
eg. I've left Shanghai for three days.(×) I've been away from Shanghai for three days.( √ ).
I left Shanghai three days ago. ( √ ) It is /has been three days since I left Shanghai.( √ )
2.初中英语课本中常见终止性动词有:leave, go, come, arrive, begin, buy, borrow, die, join, become等.终止性动词要表示持续时, 可用以下方法:
⑴.将时间状语改为时间段 + ago,句中谓语动词用一般过去时.
eg.我弟弟参军两年了. My brother joined the army two years ago.
⑵.若保留for+时间段,since+时间点/从句, 或用在 how long 句型中,则需将终止性动词改为相应的状态动词或延续性动词
常见终止性动词与延续性动词(或状态动词)的对应关系如下
come/go/arrive/get/reach/move------be in/at open-----be open
die------be dead close----be closed become---be borrow---keep begin/start-----be on put on----wear
leave-----be away (from) buy-----have fall asleep----be asleep
end/finish-----be over catch a cold-----have a cold
join the army----be in the army be a soldier join the Party----be in the Party be a Party member
→My brother has been in the army for two years. →My brother has been a soldier for two years.
3.现在完成时中been to,gone to和been in/at been to去过某地,表示某人的一种经历,可以和once,twice,already,ever,never等连用. eg. She has been to Shanghai twice. (表示目前人在这里)
gone to 去某地了,说话时某人已离开此地,在去某地的途中或已在某地,
eg. She has gone to Shanghai。 (表示现在她人不在这里)
been in/at 逗留在某地(已经一段时间).常和for ten days,since I came here等连用.
eg. She has been in Shanghai since she moved there.
4.现在完成时和一般过去时的区别
现在完成时所表明的是过去发生的动作对现在的影响,强调的是现在的情况,不可以和表示过去的时间状语yesterday,in 1991,three days ago last time,last night等连用一般过去时表明的是过去发生的事实,和现在不发生关系.
5.现在完成时中的 for 与 since
for + 时间段 与延续性动词的现在完成时连用 since + 时间点/从句
I have kept the library book for a week.= I have kept the library book since a week ago.
6. It is /has been +一段时间 + since 从句.自从某事发生已有一段时间了. eg. It is /has been two years since my brother joined the army. 注意:1.since 引导的从句中动词用过去时
2.when 引导 的特殊问句不与现在完成时连用.
3.have got,has got 虽然是现在完成时,但have got=have has got==has
宾语从句
在句子中起宾语作用的从句叫做宾语从句。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。
一宾语从句用法
时态：
1.主句用一般现在时，从句可用任意时态。
2.主句用过去时，从句用过去某个时态。
3.主句用过去时，从句是客观真理时，只用一般现在时。 一、宾语从句的连接词

五、if,whether在宾语从句中的区别
① if和whether在作“是否”解时,引导宾语从句常放在动词know,ask,care,wonder,find out等之后,介词后一般不用if
② 少数动词,如:leave,put,discuss,doubt后的宾语从句常用whether.
③ whether后可以加or not,但是if不可以.
④ 在不定式前只能用whether.
（如：I can’t decide whether to stay. 我不能决定是否留下。）
⑤ 避免歧异时,我们常用whether而不用if.
六、哪些宾语从句不可以省略引导词that
当that作learn,suggest,explain,agree,wonder,prove,mean,state,feel,hold等动词的宾语时;
当宾语从句较长时;
当主语状语置于主句尾,宾语从句之前时;
当主语谓语动词(包括非谓语动词)与宾语从句之间有插入语时;
当一个动词带有两个或两个以上宾语从句时,此时第一个that可以省略,第二个that不可以省略;
当宾语从句中的主语是this,that或this,that做主语的定语时;
当宾语从句是双宾语中的直接宾语时;
当宾语从句的主语是非谓语动词或主语从句时;
当主语中的谓语动词是固定词组时;
当宾语从句有it做其先行词时;
在直接引语中,转述分句把宾语从句隔开时.
七、宾语从句的否定转移
宾语从句的反意疑问句
主句的谓语动词是think,believe,imagine,suppose,consider,expect,fancy,guess等,并且主句的主语是第一人称而且为一般现在时,从句的否定词一般要转移到主句上来,其反义疑问句一般与宾语从句一致.

我们发现他从来不仔细听老师讲课,是不是?
八、宾语从句的时态和语序
当主句为现在时或将来时,宾语从句的时态一般不受主句的时态所影响.
当主句为过去时
①从句用一般过去时或过去进行时表示与主句谓语动词动作同时发生
I only knew he was studying in a western country,but I didn’t know what country he was in.
我只知道他当时在西方的一个国家读书,可不知道是哪个国家.
He asked me if I was reading the story The Old Man and the Sea when he was in.

记者问政府是否会采取必要的措施镇压骚乱.
如果从句是一个客观真理,那么从句的时态不根据主句的时态而变化
The teacher said that the moon goes around the earth yesterday.
老师昨天说月亮绕着地球转.
当宾语从句的引导词是who,which,what,when,where,how,why等表疑问时,不能按正常语序安排,经常将这类引导词置于句首
Who do you think the public might choose as their favorite singer this year?
你认为今年公众会选谁为他们最喜欢的歌手.
从句（Subordinate Clause）是复合句中不能独立成句，但具有主语部分和谓语部分，由that、who、whom，when，why，where。how，which等引导词（Connective）引导的非主句部分。
从句的分类
从句不能单独成句，但它也有主语部分和谓语部分，就像一个句子一样。所不同在于，从句须由一个关联词（connective）引导。 根据引导从句为主不同大大可分为：主语从句、表语从句、宾语从句、定语从句、状语从句等。从句有主语从句、表语从句、宾语从句、同位语从句、定语从句和状语从句6类。前四类由于主语从句、表语从句、宾语从句及同位语从句在句子的功用相当于名词，所以通称名词性从句；定语从句功能相当于形容词，称为形容词性从句；而状语从句功能相当于副词，称为副词性从句。状语从句还可以分为条件状语从句、原因状语从句、方位状语从句和时间状语从句。
1.主语从句（Subject Clause）：用作主语的从句叫主语从句。引导主语从句的关联词有从属连词、疑问代词、疑问副词、缩合连接代词、缩合连接副词等。
2.表语从句（Predicative Clause）：用作表语的从句叫表语从句。引导表语从句的关联词与引导主语从句的关联词大都一样。
3.宾语从句（Object Clause）：在句子中起宾语作用的从句叫做宾语从句.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。
4. 同位语从句是名词性从句(主语从句、表语从句、宾语从句、同位语从句)中的主要从句之一，从句作同位语表示与之同位的名词(短语)的实际内容，它的作用相当于名词，对前面的名词(短语)加以补充说明或进一步解释，相当于一个表语从句，它们之间的关系是同位关系，即主表关系。
5.定语从句是由关系代词或关系副词引导的从句，其作用是作定语修饰主句的某个名词性成分，相当于形容词，所以又称为形容词性从句，一般紧跟在它所修饰的先行词后面。
6.状语从句可分为：
(1)时间状语从句：(adverbial clause of time)
(2)地点状语从句：(adverbial clause of place)
(3)原因状语从句：(adverbial clause of cause)
(4)条件状语从句：(adverbial clause of condition)
(5)目的状语从句：(adverbial clause of purpose)
(6)让步状语从句：(adverbial clause of concession)
(7)比较状语从句：(adverbial clause of comparison)
(8)方式状语从句：(adverbial clause of manner)
(9)结果状语从句：(adverbial clause of result)
宾语从句
定义
宾语从句就是一个句子作动词或介词的宾语。
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…or not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。
★当who为主语时，句式为：who+谓语+其他
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
3.主句是一般将来时，一般从句为一般现在时（“主将从现”）
例题：
〈1. The teacher told the children that the sun＿＿＿＿ round.
A. was B. is C. were D. are
选B，因其陈述为无可争议的客观事实
〈2. I believe that our team＿＿＿＿ the basketball match.
A. win B. won C. will win D. wins 选C ，这是讲话人现在对将来情况的主观推测
〈3.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3：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…
宾语从句，在复合句中作宾语，位于及物动词后；
Tell him which class you are in ．
Do you know what he likes？
(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；
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；
He told me that he was born in 1980.
宾语从句
宾语从句就是在复合句中作宾语的名词性从句，通常放在主句谓语动词（及物动词）或介词之后。
1. 作动词的宾语
(1) 由that引导的宾语从句（that 通常可以省略）,例如：
I heard that be joined the army.
(2) 由what, whether (if) 引导的宾语从句，例如：
1) She did not know what had happened.
2) I wonder whether you can change this note for me.
(3) 动词＋间接宾语＋宾语从句。例如：
She told me that she would accept my invitation.
2. 作介词的宾语
例如：Our success depends upon how well we can cooperate with one another.
3. 作形容词的宾语
例如：I am afraid (that) I’ve made a mistake.
That 引导的从句常跟在下列形容词后作宾语：
Anxious, aware, certain, confident, convinced, determined, glad, proud, surprised, worried, sorry, thankful, ashamed, disappointed, annoyed, pleased, hurt, satisfied, content 等。也可以将此类词后的that 从句的看作原因状语从句。
4. It 可以作为形式宾语
It 不仅可以作为形式主语，还可以作为形式宾语而真正的宾语that 从句则放在句尾，特别是在带复合宾语的句子中 。 例如：
We heard it that she would get married next month..
5. 否定的转移
若主句谓语动词为Think, consider, suppose, believe, expect, fancy, guess, imagine等，其后的宾语从句若含有否定意义，一般要把否定词转移到主句谓语上，从句谓语用肯定式。例如：
I don’t think this dress fits you well.（我认为这件衣服不适合你穿。）
1、时间状语从句
（1）as、when、while
类别 作 用 例 句
as as表示“当……的时候”，往往和when/ while通用，但它着重强调主句与从句的动作或事情同时或几乎同时发生。 She came up as I was cooking.(同时)
The runners started as the gun went off.(几乎同时)
when (at or during the time that )既可以表示在某一点的时候，又可表示在某一段时间内，主句与从句的动作或事情可以同时发生也可以先后发生。 It was raining when we arrived.(指时间点)
When we were at school, we went to the library every day.(在一段时间内)
while while意思是“当……的时候”或“在某一段时间里”。主句中的动作或事情在从句中的动作或事情的进展过程中发生，从句中的动词一般要用延续性动词。在when表示a period of time时，两者可以互换。 Please don’t talk so loud while others are working.
He fell asleep while/when reading. Strike while the iron is hot.(用as或when不可，这里的while意思是“趁……”)
（2）引导时间状语从句的连接词除上述外还有：
①till, not … until …, until, before, since
Don’t get off the bus until it has stopped.
He waited for his father until(till)it was twelve o’clock.
It will be five years before he returns from England.
②hardly / scarcely … when, no sooner … than, as soon as once
表示“一……就”
As soon as I hxdye finished it , I’ll give yu a call.
Once you show any fear, he will attack you.
We had hardly got / Hardly had we got into the country when it
began to rain.
No sooner had he arrived / He had no sooner arrived than she started complaining.
③directly, immediately, the moment, the minute that… 一……就
He made for the door directly he heard the knock.
④each time, every time, by the time
Each time he came to my city, he would call on me.
注意：表示未来情况，主句用将来时，从句用现在时。
2、让步状语从句
（1）although与though可以引导让步状语从句，不能与but连用，但可以与yet连用。
Although they are poor,(yet)they are warm-hearted.
（2）even if或even though引导让步状语从句，表示“即使”，“纵然”，用来使人注意下文所强调内容的性质。
I’ll get there even if(though)I hxdye to sell my house to get enough money to go by air.
（3）no matter后接上who、what、where、how等疑问词，也可以在这类疑问词后面加上ever构成whoever、whatever、wherever、however等。
Don’t trust him, no matter what / whatever he says.
Whoever breaks the law will be published.
No matter how hard the work is, you’d better try to do it well.
（4）as也可以引导让步状语从句。要用倒装。
Child as(though)he is, he knows a lot.
Much as I like it, I won’t buy.
Try as he would, he couldn’t lift the hexdyy box.
3、原因状语从句：because, for, as, since, now that
（1）表示不知道的原因时用because,即说话人认为听话人不知道，因此because从句是全句最重要的部分，通常它被置于主句之后。
You want to know why I’m lexdying? I’m lexdying because I’m full.
for虽然表示不知道的原因，但其语气较because要弱得多，是可说可不说的话，它只能置于主句之后，这时，for是并列连词。如果不是因果关系，而是对前面主句的内容加以解释或推断时，只能用for。如：It’s morning now, for the birds are singing.（很显然，鸟叫不可能是“现在已是早上”的原因。）
（2）表示已经知道的原因时用as或since,即某种原因在说话人看来已经很明显，或已为听话人所熟悉，因此它是句中不很重要的部分。since要比as正式一些，它们通常被置于语句之前，但有时却相反。
Seeing all of the children already seated, he said,“Since everyone is here, let’s start.”
(3)下列情况下只能使用because:
①在回答why的问句时；
②在用于强调句型时；
③被not所否定时。
4、地点状语从句：where, wherever
Make a mark wherever you have any questions.
We will go where the Party directs us.
order that
注意：目的状语从句的谓语动词常与情态动词连用，否则可能是结果状语从句。不可置于句首。
6、结果状语从句：that, so that, so … that, such … that …
注意：so + 形容词/副词 + that从句；such + 名词 + that从句。
7、方式状语从句：as, as if(though)
I’ll do as I am told to.
It looks as if it is going to rain.
8、比较状语从句：than, as
9、条件状语从句：if, unless, so (as) long as, in case, once, a far as, on condition that.
注意if与unless的区别：不能用and连接两个unless从句，即不能有… unless …,and unless … 。但if … not and if … not却不受此限。
You won’t lose your weight unless you eat less and unless you exercise more.(×)
但可以说 … unless you eat less and exercise more.
10、注意状语从句中从句的省略现象
（1）连接词 + 过去分词
Don’t speak until spoken to.
Pressure can be incrased when needed.
Unless repaired, the washing machine is no use.
（2）连词 + 现在分词
Look out while crossing the street.
（3）连词 + 形容词/其他
常见的有it necessary、if possible、when necessary、if any等。
表语从句
表语从句在复合句中作表语的名词性从句，放在系动词之后，一般结构是“主语＋连系动词＋表语从句”。可以接表语从句的连系动词有be, look, remain, seem等。引导表语从句的that常可省略。另外，常用的还有the reason is that… 和It is because 等结构。例如：
1) The question is whether we can make good preparation in such a short time.
2) This is why we can’t get the support of the people
3) But the fact remains that we are behind the other classes.
4) The reason he is late for school is that he missed the early bus.
同位语从句
同位语从句就是在复合句中作名词的同位语的名词性从句。
1. 同位语从句的功能
同位语从句对于名词进一步解释，说明名词的具体内容，一般由that引导，例如：
1) The king’s decision that the prisoner would be set free surprised all the people.
2) The order that all the soldiers should stay still is given by the general.
2. 同位语在句子中的位置
同位语从句有时可以不紧跟在它所说明的名词后面，而是被别的词隔开。例如：
He got the news from Mary that the sports meeting was put off.
3. 同位语从句与定语从句的区别
(1) 定语从句中的that既代替先行词，同时以在从句中作某个成分（主语或宾语），而同位语从句中的that是连词，只起连接主句与从句的作用，不充当句中任何成分。
(2) 定语从句是形容词性的，其功能是修饰先行词，对先行词加以限定，描述定的性质或特征；同位语从句是名词性的，其功能是对名词进行补充说明。例如：
1) The news that he told me is that Tom would go abroad next year.（他告诉我的消息是汤姆明年将出国。）（第一个that引导的从句是定语从句，that在从句中作宾语）
2)The news that Tom would go abroad is told by him.（汤姆将出国的消息是他讲的。）（同位语从句，that在句中不作任何成分）
状语从句和宾语从句的区别~
首先是成分不同，你看到一个句子就分析主谓宾，当动词后面的部分为句子，且就是动词的宾语就是宾语从句了。但这个动词是及物动词，直接接宾语的，如果是不及物动词后面接宾语从句，一般从句就放在相应的介词后面。因为不及物动词是不能直接加宾语的。当你看到一个句子的主谓宾都完整了，后面却还有个从句，一般引导词为where，when，why，how，if条件句，so
that（目的状语）。。。且这些引导词在从句中不作任何成分。这个句子就是状语从句了。

状语从句的连词
具体内容（一）宾语从句定义：用作宾语的从句叫宾语从句。
（二）构成：关联词

（三）引导宾语从句的关联词有三类：1.
从属连词that。如：He
told
us
that
he
felt
ill.
他对我们说他感到不舒服。I
know
he
has
returned.
我知道他已经回来了。注：that在引导宾语从句时也并不是任何情况下都可以省略。在以下情况下，that不能省略。（1）Everybody
could
see
what
happened
and
that
Tom
was
frightened.（and连接两个宾语从句，that宾语从句放在and的后面时，that不能省略。）大家都会看出所发生的事情并知道Tom非常害怕。（2）I
know
nothing
about
him
except
that
he
is
from
the
south.

如何区分宾语从句,状语从句 - ******
#颛欣# 宾语从句:有what\which\that引导句子在整个句子充当宾语成分,就是宾语从句. eg:i don't know what to do.i don't know which one is the best.我不知道该做什么.我不知道哪一个是最好的.状语从句:以时间,原因,等引导词在整个句子中充当状语成分的就是状语从句.eg:i don't know she is my english teacher when i see her at first time.我第一眼见到她的时候,不知道她是我的英语老师.

#颛欣#[答案] 定语从句,宾语从句,状语从句,表语从句都是用来修饰的,顾名思义,定语从句就是修饰定语的,所以你要分好什么是定语宾语.之类的.一个句子结构有可能是主系表,主谓宾.定语是修饰名词的,这个名词可能是主语或谓语,然后定语...

怎么区分 英语中宾语从句 状语从句 同谓语从句 定语从句 - ******
#颛欣# 主谓宾分的清吧,能的话就好办了,一个句子最基本的结构就是主语+谓语+宾语比如,(我爱你)就是典型的主谓宾结构我是主,爱是谓,你是宾. 整个句子如果作为宾语那这个句子就叫宾语从句,壮语从句是修饰谓语的,整个一个句子作宾语的话就叫宾语从句.同位语就更好理解了,和被修饰的词并列但是进一步解释所修饰的内容的句子就是了.
