我的建议是我们应该去帮助他.

Our only request is that this should be settled as soon as possible.

宾语从句的连接词做表语例句=10分

1 whom he is waiting 在整个句子中是宾语从句,whom是引导词,在宾语从句中充当for的宾语,不是表语。

i don't know who he is。

这句who he is 就是宾语从句,who 引导词做is 的表语。

我觉得楼主应该先了解,什么是表语,什么是宾语,从你对这句的的理解,你是没有把这两个概念搞明白的。

2 这个句子互换是可以的,但是从顺口的角度来说,第一种是习惯性的用法。

第二个仿佛不怎么这么说。

我输入了GOOGLE来看,那个用法更多,明显是第一种。

而且第二中出现的最高频率,也是像楼主这样问的用法,所以我觉得,第一种更好。

whether/if引导的宾语从句

1whether和if都可以引导宾语从句,表示“是否”,在口语或间接引语中两者可以互换使用。

如: I wonder if / whether I can get some advice from you. Ask him whether / if he can come. 但在有些情况下,whether和if的用法有一定区别。

1. whether引导的从句常可以与连词or或or not直接连用,而if一般不能。

如: 正: Let me know whether you can come or not. 误: Let me know if you can come or not. 2. 当宾语从句提到句首时,只能用whether引导,而不能用if。

如: 正: Whether it is true or not, I can't tell. 误: If it is true or not, I can't tell. 3. whether可以引导带to的不定式,if则不能。

如: 正: I don't know whether to accept or refuse. 误: I don't know if to accept or refuse. 4. whether及其引导的成分可放于介词之后,作介词的宾语,但if不能。

如: 正: I worry about whether I hurt her feelings. 误: I worry about if I hurt her feelings. 5. whether可以引导从句,作主语、表语或同位语,而if不能。

如: 正: It was uncertain whether he would come. 误: It was uncertain if he would come. 正: His first question was whether Tom had arrived yet. 误: His first question was if Tom had arrived yet. 正: We must consider the question whether we will take these measures. 误: We must consider the question if we will take these measures.

if 与 whether

没有错误if和whether引导表语从句 引导表语从句时,一般用whether.例如: The question is whether they can cooperate with us.问题是他们能否与我们合作。

The question I whether we can get there in time. 有的语法认为if 也可以引导表语从句,例如: The first question I put to him was whether/if he would do it. Our only problem is if someone gets that brilliant notion first. 不过,对中学生来说,这种用法还是尽时不时避免为好。

竭诚相助,希望采纳!!!!

表语从句是什么?表语又是什么?举些例子在讲解下吧。

表语从句 一 定义: A 表语从句就是用一个句子作为表语。

说明主语是什么或者怎么[1]样,由名词、形容词或相当于名词或形容词的词或短语充当,和连系动词一起构成谓语。

The problem is puzzling. 主语 连系动词 形容词作表语The problem is when we can get a pay rise. 主语 连系动词 一个句子作表语---表语从句B 连接表语从句的连接词有:that, what, who, when, where, which, why, whether,how.He has become a teacher. He has become what he wanted to be ten years ago.She has remained there for an hour. She has remained where I stood yesterday for an hour.His suggestion is good. His suggestion is that we should stay calm.The question is confusing. The question is when he can arrive at the hotel.who will travel with me to Beijing tomorrow. why he cried yesterday.how I can persuade her to join us in the party. whether the enemy is marching towards us. 二 注意:A 表语从句一定要用陈述语序。

False: The question is when can he arrive at the hotel. Right: The question is when he can arrive at the hotel.B 不可以用if,而用whether 连接表语从句(as if 例外)。

引导宾语从句时可以互换if/whether 位于介词后要用whether 位于句首时要用whether 引导表语从句,主语从句,同位语从句时要用whether False: The question is if the enemy is marching towards us. Right: The question is whether the enemy is marching towards us. Right: It looked as if he had understood this questionC 不像宾语从句,在有表语从句的复合句中,主句时态和从句时态可以不一致。

Right: The question is who will travel with me to Beijing tomorrow. Right: The question is why he cried yesterday.D that在表语从句中不可以省掉。

表语从句的基本用法表语从句只能置于主句之后,而主句的动词只能是联系动词。

名词性从句在be等系动词后作表语时被称为表语从句, 例如: 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) 注意: “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, 又如: That is why you see this old woman before you know, Jeanne. 珍妮, 这就是现在这个老太婆出现在你面前的原因。

(前文提到Jeanne对老妇人显得苍老憔悴深感诧异, 说话人对她讲述了其中的原因之后,用这一句来进行概括)。

// That is why I came. 这就是我来的原因。

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, 例如: That is why I cannot agree. 这就是我不能同意的理由。

(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, 例如: 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)

英语中主系表结构后跟什么(表语为形容词)

The question is .句子主干是:the question is whether 引导的句子,做the question is 的表语从句。

whether是表语从句的引导词。

She doesn't know whether to say or not.句子主干是she doesn't know. whether to say or not是know的宾语。

定语和表语的区别

1、定语是修饰名词或代词的成分,不管这个名词在句中是作主语、表语、宾语,定语都是可以修饰名词或代词的。

定语是个修饰成分,把它去掉句子仍然通顺,只是在句意上有出入如 he is a good student 。

中good 为 定语,修饰名词 student,把good去掉,句子仍然通顺。

2、表语。

主要用与主语+系动词+表语。

这个结构,它是句子不可缺少的成分。

如 he is a student。

中 a student 是表语,不能删除。

ps:作表语的词或短语有:1、名词 he is a good student2、形容词 he is good3、介词词组 he is at home4、少数副词 he is there5、数词、3 and 4 is 7 6动名词和不定词: his jod is to take care of the boy 7、表语从句 the problem is whether he will come

whether引导的让步状语从句,从句谓语用什么,主句谓语用什么,...

⑴though,although表示“虽然,纵然”之意。

这两个连词意思大致相同,在一般情况下可以互换使用。

在口语中,though较常使用,although比though正式,二者都可与yet,still或never,the less连用,但不能与but连用。

例如:My will is strong though I must lower my physical sights.尽管我得降低体育(锻炼)的目标,但我的意志是坚强的。

⑵as,though表示“虽然……但是”,“纵使……”之意。

as引导的让步状语从句必须以部分倒装的形式出现,被倒装的部分可以是表语、状语或动词原形,though也可用于这样的结构中,但although不可以这样用。

例如:Object as you may,I'll go. 纵使你反对,我也要去。

⑶even if,even though 表示“即使……”,“纵使……”之意,含有一种假设。

这两个复合连词的意思基本相同。

它们常互换使用,但意义有细微差别。

even if引导的让步从句含有强烈的假定性,可用来表示与事实相反的假设,但不能用来描述已经发生的事实。

而even though引导让步状语从句时,是以从句的内容为先决条件的,即说话人肯定了从句的事实,表示已经发生了的事。

例如:We'll make a trip even if/though the weather is bad.即使天气不好,我们也要作一次旅行。

however的让步状语从句用法。

一、however 有两种用法1、转折副词:用来对一个“简单句”在程度或广度上作出让步转折,总是以插入语形式出现,用逗号隔开插入到句子中间,也可以插入到句尾。

用作插入语时,可以单独使用,也可以修饰形容词或副词。

如:We have not yet won; however, we shall try again. 我们还没有取胜, 不过我们还要再试一下。

(句中,单独使用) He wanted to take no risks, however small.他多小的风险都不敢冒。

(句尾,修饰补充说明 risks程度的形容词small)2、引导状语从句的连接副词:用来引导“复合句中”的让步状语从句。

从句在前时用逗号与主句隔开;主句在前时从句前一般不用逗号,除非从句较长,一口气读会憋气。

However you look at it,it's going tocost a lot. 不管你怎么看,它都要花很多钱。

(从句在前) In one's own home one can act however hewishes. 在自己家里一个人想干什么都行。

(从句在后) Wear your hair, whether or not you want tosee your girl friend whom you have not seen for a long time. 不管你是否去见很长时间没有见到的女朋友,都请把自己头发整理一下。

(在后的从句较长) 让步状语从句的虚拟语气的用法 引导让步状语从句的连词有as、though、even if、even though、whatever、however、whichever、whenever、wherever、no matter what、no matter where、no matter which、no matter when、whether …or…等等。

1.as和though。

意思:尽管。

as用于引导让步状语从句,只能用倒装句式,并且通常可以与though互换。

句子通常用陈述语气。

但有时从句也用“may [might, would]+动词原形”这样的虚拟语气。

例如: Hard as she works, she might fail the exam. 尽管她努力,但是有时还是可能会考试失败。

Strange though it may seem, he completely the task perfectly. 尽管看来很奇怪,他却完美地完成任务。

2.even if和even though。

意思:即使。

他们可以互换。

even if 引导的让步状语从句,形式同if引导的虚拟条件句相似。

例如: I won't give up even though I should fail ten times. 即使失败十次,我也不会放弃3.whatever或no matter what:无论什么.....;however或no matter how:无论怎样......;wherever或no matter where:无论哪里;whichever或no matter which:无论哪个;whenever或no matter when:无论何时;whether …or…无论....还是......。

whatever、no matter what 等whether …or…引导的让步状语从句中,虚拟语气主要表示不确定或没有把握等,通常用指现在或将来,谓语用“may +动词原形”;指过去,谓语“may+动词完成式或是与条件虚拟语气相似的句型。

例如: However dull he may be, he is certainly a very sucessful executive.无论他是多么无趣的人,他肯定是一个非常成功的管理人员。

We will find him wherever no matter where he may be. 无论他在哪里,我们都要找到他。

I will wait for him no matter how however late he may come. 不管他来的多么晚,我都会等他。

Whatever happened, we must keep calm. 不管发生什么情况,我们都必须保持镇静。
