什么是从句,在句子中有何作用.
什么是从句,在句子中有何作用.
　一.主语从句　　主语从句是在复合句中充当主语的从句,通常放在主句谓语动词之前或由形式主语it代替,而本身放在句子末尾.　　1. It 作形式主语和it引导强调句的比较　　It 作形式主语代替主语从句,主要是为了平衡句子结构,主语从句的连接词没有变化.而it引导的强调句则是对句子某一部分进行强调,无论强调的是什么成分,都可用连词that.被强调部分指人是也可用who/whom.例如：　　It is a pity that you didn’t go to see the film.　　It doesn’t interest me whether you succeed or not.　　It is in the morning that the murder took place.　　It is John that broke the window.　　2. 用it 作形式主语的结构　　(1) It is +名词+从句　　It is a fact that … 事实是…　　It is an honor that …非常荣幸　　It is common knowledge that …是常识　　(2) it is +形容词+从句　　It is natural that… 很自然…　　It is strange that… 奇怪的是…　　(3) it is +不及物动词+从句　　It seems that… 似乎…　　It happened that… 碰巧…　　(4) it +过去分词+从句　　It is reported that… 据报道…　　It has been proved that… 已证实…3. 主语从句不可位于句首的五种情况　　(1) if 引导的主语从句不可居于复合句句首.　　(2) It is said , (reported) …结构中的主语从句不可提前.例如：　　It is said that President Jingo will visit our school next week. (right)　　That President Jiang will visit our school next week is said. (wrong)　　(3) It happens…, It occurs… 结构中的主语从句不可提前.例如：　　It occurred to him that he failed in the examination. (right)　　That he failed in the examination occurred to him. (wrong)　　(4) It doesn’t matter how/whether …结构中的主语从句不可提前.例如：　　It doesn’t matter whether he is wrong or not. (right)　　Whether he is wrong or not doesn’t matter. (wrong)　　(5) 含主语从句的复合句是疑问句时,主语从句不可提前.例如：　　Is it likely that it will rain in the evening? (right)　　Is that will rain in the evening likely? (wrong)　　4. What 与that 在引导主语从句时的区别　　What 引导主语从句时在句时在从句中充当句子成分,如主语.宾语.表语,而that 则不然.例如：　　1) What you said yesterday is right.　　2) That she is still alive is a consolation.二.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. 后边不能直接跟that 从句的动词　　这类动词有Allow, refuse, let, like, cause, force, admire, condemn, celebrate, dislike, love, help, take, forgive等.这类词后可以用不定式或动名词作宾语,但不可以用that引导的宾语从句.例如：　　I admire their winning the match. (right)　　I admire that they won the match. (wrong)　　6. 不可用that从句作直接宾语的动词　　有些动词不可用于“动词+间接宾语+that从句“结构中,常见的有Envy, order, accuse, refuse, impress, forgive, blame, denounce, advise, congratulate等.例如：　　He impressed the manager as an honest man. (right)　　He impressed the manager that he was an honest man. (wrong)　　7. 否定的转移　　若主句谓语动词为Think, consider, wuppose, 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.)三.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.　　四.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)
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。
从句不能单独成句，但它也有主语部分和谓语部分，是一个特殊句子，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。
从句不能单独成句，但它也有主语部分和谓语部分，是一个特殊句子，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。根据从句语法功能的不同可分为：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，...从语法角度看,下面句子中的“that”引导的是什么性质的从句?We are glad that our efforts has addressed all your concerns.has 应为 have_作业帮

从语法角度看,下面句子中的“that”引导的是什么性质的从句?We are glad that our efforts has addressed all your concerns.has 应为 have
“that”引导的是名词性从句 作形容词的宾语某些表示主观感受的形容词,在语义逻辑上等同于谓语表达,此时后面连接的名词性从句可理解为它的宾语,即形容词宾语从句.例如：We are fully convinced that John was the winner of the speech contest.【译文】我们完全相信约翰是此次演讲比赛的获胜者.I am afraid that you,ve misunderstood your boss.【译文】我担心你误解了你的老板.We are not sure whether/if we can persuade him out of smoking.【译文】我们不能确定能否说服他戒烟.形容词宾语从句此类的形容词常见的还有：ashamed,anxious,aware,annoyed,certain,confident,convinced,disappointed,determined,glad,proud,pleased,satisfied,surprised,sorry,thankful,worried 等英语中 一个句子能有几个动词?（这个句子没有从句 之类 的 句子）_作业帮

英语中 一个句子能有几个动词?（这个句子没有从句 之类 的 句子）
楼主!可以有N个动词 【但是只能有一个谓语动词或系动词】若不是谓语动词或系动词 必须转化为 “非谓语动词” 非谓语动词：+ing（与主语是主动关系） 或者 +ed（与主语是被动关系）
加be动词2个，从句除外
英语句子分为三种：简单句 并列句 复合句简单句一般只能有一个动词。并列句可以有任意个动词，比如你一直用and or but等连接分句子，动词个数比连词个数多一个。复合句一般讲指包含从句。与你的问题不同。
英语中，正确的语法规定，一个句子中，只能有一个动词来作为谓语，即谓语动词。在句子的其他成分中，还可以出现其他动词情况，如不定式 to do 来表示目的等。从句中当然也可以有动词啦，从句是一个完整结构的句子，也需要谓语动词，这与主句的谓语动词不相关。当你判断句子的动词时，只要找出句子的主语，宾语，那么主语对宾语的动作就是谓语动词啦。...
这个可不好说，如果故意造句的话，可以放很多动词进去。不过一般就是两三个动词放在一起表达一句话的。这两三个可是包括了To动词不定式和各种动名词的变形啊

宾语从句 【复习目标】 ▲掌握宾语从句的语序.▲掌握引导宾语从句的各种连词.▲掌握宾语从句中,主句与从句在时态上的相互呼应.【课前准备】要求学生回顾宾语从句的概念及其用法,并用各种引导词各造一个句子.【知识要点】 1.宾语从句在句中作及物动词或介词的宾语,从句放在主句之后,前后不用逗号分开.2.引导宾语从句的词有：连词that(在口语中that常可省略),if,whether,如：He knows that Jim will work hard.连接代词who,whom,which等,如：Do you know who (whom) they are waiting for?连接副词when,where,how,why等,如：Could you tell me how we can get to the station?3.whether和if都有“是否”的意思,一般情况下两者可以换用,但在介词之后,不定式之前,与or not连用,在句首或在引导表语从句,同位语从句时,只能用whether,如：I want to know if/whether the news is true.He doesn't know whether to stay or not?4.宾语从句要用陈述句语序.5.宾语从句一定要注意时态呼应,即：当主句谓语动词是过去式时,从句中谓语动 词也要用过去范畴的时态,但若从句陈述的是真理或客观规律,其谓语的时态仍用一般现在时,如：He asked who could answer the question.My father told me that the earth goes around the sun.6.一个宾语从句只能用一个连词.7.当主句谓语动词是think,believe等动词时,宾语从句的否定意义要放到主句中.另外,当主句主语为第一人称时,后面若接附加疑问句,那么附加疑问句的主语、谓语应与从句中的主谓语保持一致.如：I don't think he looks like his father,does he?8.直接引语和间接引语也是宾语从句,直接引语是引述别人的原话,放在引号内,不用连词联接；间接引语是用自己的话转述别人的话,通常用连接词与主句联接.(1)陈述句变为以that引导的宾语从句,如：He said,“I'm happy.”[FY()[FY]]He said that he was happy.(2)一般疑问句变为if(whether)引导的宾语从句,如：He asked me,“Does his father know Mr Green?” ---He asked me if his father knew Mr Green.(3)特殊疑问句变为由who,what,where,how等疑问词(连接代词或连接副词)引导的宾语从句,如：He asked me,“Where is Mr Wang?” ---He asked me where Mr Wang was.注意上述例句中连词、时态、语序等变化.宾语从句 【常见用法：】 常由that引导,在口语中常省略.当主句中谓语动词是现在或将来时态时,从句中谓语动词不受主句中谓语动词时态的影响,按需要可以使用任何时态.当主句谓语是过去时态,而宾语从句叙述某一客观真理（事实）时,宾语从句的时态则用一般现在时.由连接代词或连接副词引导的宾语从句.引出名词性从句的连词whether和if,在引出宾语从句时,用法和意义相同.但是只能引出宾语从句和不在句首的主语从句,而whether除了引出宾语从句外,还可引出主语从句、表语从句和同位语从句.
用句子还原就行了
您好！我可以尝试回答您的问题。who 是单数概念。who 一般情况下是做链接词 像 that 一样。你应该知道。例如：I know there are many people there who speak French.Who 可以做单数也可以当复数。因为这是个疑问词，不知道是一个还是多个。当然 Who也可以做主语，也是可以是单复数。who 有多种用法。whom是who 的宾格。如果你...高一定语从句里的例如WHICH和介词加WHICH用法到底有什么区别?举几个例子.高一定语从句的难点,那个高手会的话讲讲,_作业帮

which 用于定语从句,作关系代词,在句中要做成分 in which 用于定语从句,作关系副词,在句中不做成分,in which=wherein which 只能用在定语从句中,等于where,在定语从句中作状语.如：He lived in the house in which Tom once lived.He lived in the house where Tom once lived.定语从句中.如 this is the room in which we stayed 先行词是room,后的句子是用来修饰room的 但是room不可做stay的成分,因为stay是不及物动词,后不可直接家宾语 所以要有个介词． 其实上述的句子＝ this is the room which we stayed in． 这里的介词是可以提到which 前的 注意,第二个句子可用that 或省略 但第一个只能用which．只有which前可加介
