下面是小编整理的一些关于all的用法总结, 希望对大家的英语学习有帮助。
1. 与定冠词、指示代词、形容词性物主代词、名词所有格等限定词连用时,all 应放在这些词之前 (而不是之后),并且一般可在它们之间加介词 of (也可省略)。
如:all (of) the people 所有这些人 all (of) her children 她所有的孩子 all (of) these rooms
所有这些房间关于此类结构,注意以下几点:
(1) 在 all of the people这类结构中,若省略介词 of, 则其中的冠词也可略,但是若不省略介词 of, 则其中的冠词不能省略。如:正:all of the children / all the children / all children误:all of children 也就是说:只有当名词前有限定词修饰时,其前才可用 all of (并且of可省略);若名词前没有限定词修饰 (即单独使用),则其前不能用of。如:of
正:all of my books / all my children / all children
误:all of books
(2) 在人称代词前必须用 all of (不能省略介词 of)。如:all of us我们所有的人 all of them 他们所有的 (人 / 物)
1. 与all应置于其前。如:All suchbooks are very expensive. 所有那样的书都很昂贵。All otherchildren are in the classroom. 所有其他的孩子都在教室。
3. all 用作主语同位语时,其位置不一定是紧跟在主语之后,而通常放在行为动词之前
3. (动词 be、情态动词、助动词)之后。
如:The children were all late. 孩子们都迟到了。
They have allread the book. 他们都读过这本书。
但是若特殊动词和all位于句末,则应将all 放在特殊动词之前。如:You are all silly. 你们都很傻。--->How silly you all are! 你们多么傻呀!
They haven’t been there, but we all have. 他们没去过那儿,但我们都去过。
4. all All is silent. 万籁俱寂 (指现象)。All are silent. 人人都沉默不语 (指具体的人)。
5. all 与 not连用,通常表示部分否定。如:Not all the books areinteresting. All the books are not interesting. 并不是所有的书都有趣味。
6. 用于 in all, 意为“一共”、“总共” (通常放在数字之后)。如:There are twenty in all. 一共20个。
The cost of the repairscame to $800 in all. 修理费一共800美元。
7. at all 主要用来加强语气,主要用法有:
(1) 用于否定句,意为“完全不”、“一点也不”。如:I don’t knowhim at all. 我一点不了解他。单独使用的 Not at all. 在口语中有特殊的含义,其意为“不用谢”、“没关系”,用来回答感谢或道歉。如:A:Thank you very much. 多谢你了。B:Not at all. 不客气。A:I’m sorry to keep youwaiting. 对不起,让你久等了。B:Oh, not at all. I’ve been hereonly a few minutes. 哦,没关系,我也刚到几分钟。

(2) 用于“the+比较级”结构之前,表示“更加”。如:Opening thewindows made it all the hotter. 把窗子打开更热了。
(3) 用于 all along, 意为“一直”、“一向”。不要想当然地认为它一定要与完成时连用,其实它可与现在时、过去时、完成时、进行时等时态连用。如:I know (knew) it all along. 我一直知道这事。I have all along urged him to study hard. 我一直督促他努力学习。

以下是小编为大家整理的疑问代词的用法总结,希望能帮助大家更好地认识疑问代词,提高英语水平。
1) 疑问代词在句中起名词词组的作用,用来构成疑问句。疑问代词有下列几个:
指人: who, whom, whose
指物: what
既可指人又可指物: which
2) 疑问代词在句中应位于谓语动词之前,没有性和数的变化,除who之外也没有格的变化。what, which, whose还可作限定词。试比较:
疑问代词:Whose are these books on the desk?
桌上的书是谁的?
What was the directional flow of U. S. territorial expansion?
美国的领土扩张是朝哪个方向的?
限定词:Whose books are these on the desk?
桌上的书是谁的?
What events led to most of the east of the Mississippi River becoming part of the United States? 哪些事件使密西西比河以东的大部分土地归属于美国?
说明1:
无论是做疑问代词还是限定词,which 和 what 所指的范围不同。what所指的范围是无限的,而which则指在一定的范围内,例如:
What girls do you like best?
你喜欢什么样的姑娘?
Which girls do you like best?
你喜欢哪几个姑娘?
说明2:
Whom是who的宾格,在书面语中,它作动词宾语或介词宾语,在口语中作宾语时,可用who代替,但在介词后只能用whom, 例如:
Who(m) are you taking the book to?
你要把这书带给谁?(作介词宾语,置句首)
Who(m) did you meet on the street?
你在街上遇到了谁?(作动词宾语)
To whom did you speak on the campus?
你在校园里和谁讲话了?(作介词宾语,置介词 后,不能用who取代。)
说明3:
疑问代词还可引导名词性从句,例如:
I can't make out what he is driving at.
我不知道他用意何在。
Can you tell me whose is the blue shirt on the bed?
你能告诉我床上的蓝衬衣是谁的吗?
Much of what you say I agree with, but I cannot go all the way with you.
你说的我大部分同意,但并不完全赞同。
说明4:
疑问代词用于对介词宾语提问时,过去的文体中介词和疑问代词通常一起放在句首,现代英语中,疑问代词在句首,介词在句未,例如:
For what do most people live and work?
大部分人生活和工作的目的是什么?(旧文体)
What are you looking for?
你在找什么?(现代英语)

分词分为现在分词 和过去分词 两种,是一种非谓语动词 形式。现在分词和过去分词主要差别在于:现在分词表示“主动和进行”,过去分词表示“被动和完成”(不及物动词的过去分词不表示被动,只表示完成)。分词可以有自己的状语、宾语 或逻辑主语等。以下是小编为大家整理的分词的用法总结,希望能帮助大家更好地认识分词,提高英语水平。
分词短语在句中作让步状语时,相当于一个让步状语从句,有时分词前可以带有连接词although, whether, even if, even though。
现在分词短语作让步状语,分词的逻辑主语是句中的主语,变成状语从句时,需用主动语态。
Weighing almost one hundred jin the stone was moved by him alone.
= Although the stone weighted almost one hundred jin, it was moved by him alone. 虽然那块石头重将近一百斤,他一个人就把它挪动了。

以下是小编为大家整理的spend的用法总结,希望能帮助大家更好地认识spend这个词组,提高英语水平。
1. 在使用spend时,主语只能是表示人的名词或代词。例如:
Andy spent a lot of money on books. Andy花了很多钱买书。
2. 若表示"花费(时间、金钱等)做某事",则常用句型spend some money / some time (in) doing sth.,此时第二个动词要用动词-ing形式,介词in可以省略。例如:
They spent 4450 yuan buying the big colour TV set. 他们买那台大彩电花了4450元。
另外,spend也有"度过"的意思。例如:
They want to spend their summer holiday in the country.他们想去乡下过暑假
相关近义词比较:take, cost,spend
3. 若表示"在......上花费(时间、金钱等)",常用句型spend some money/ some time on sth.,介词on后接名词或代词。例如:
Kitty spends two hours on her homework every day. Kitty每天花两个小时做家庭作业。
一、根据主语辨析
虽然三者均可表示“花费”,但所用主语不同:take 的主语可以是事或物(包括形式主语 it),也可以是人;spend 的主语只能是人,不能是事或物;cost 的主语通常是事或物(包括形式主语 it),不能是人。如:
It took me an hour to write the letter. 我写这封信花了一个小时。
I spent an hour writing the letter. (译文同上)
The letter took me an hour (to write). (译文同上)
The computer cost (me) $2000. 这台电脑花了(我) 2000 美元。
It costs $1000 a year to run a car. 使用一辆车每年要花1000美元。
I have spent all day looking for you. 我花了一整天找你。
注:若 cost 不是表示“花费”,而是表示客观地或被动地“耗费”,则也可用人作主语。如:
Smokers cost them a lot of money every year. 抽烟的人每年要耗费他们不少钱。
二、根据宾语辨析
take 的宾语通常是时间,cost 的宾语通常是钱,而 spend 的宾语则可以是时间或钱。如:
It took her two hours to walk to the station. 走路去车站花了她两小时。
He spends much time (money) on books. 他花了很多时间读(钱买)书。
How much did it cost to build the bridge? 建这座桥花了多少钱?
注:cost 有时也用于时间,但通常只用于笼统时间(一般不用于具体明确的时间)。如:
Making experiments like this costs much time and labour. 做这样的实验要花很多时间和劳力。
按传统语法,take 的宾语通常是时间,但在现代英语中,用钱作其宾语的现象已很普遍。如:
It takes a lot of money to buy a house. 买一座房子要花一大笔钱。
三、根据句型辨析
从句型结构来看。三者的通常句型为:
it costs (sb) money to do sth 做某事花某人多少钱
sb spends time (money) on sth 某人在某一方面花多少钱
sth costs (sb) money 某物花某人多少钱
sb spends time (money) in [on] doing sth 某人在做某事方面花多少钱
it takes sb time (money) to do sth = it takes time (money) for sb to do sth 做某事花某人多少时间或钱
sth takes sb time (money) to do 某事花某人多少时间或钱去做
sb takes time (money) to do 某人花多少时间或钱去做某事

以下是小编为大家整理的since的用法总结,希望能帮助大家更好地认识since这个单词,提高英语水平。
一、若since引导的状语从句的谓语动词是持续性 动词或表示状态 的动词的过去时 时,则从句表示的时间是“从那持续动作或状态结束时算起”。如:
I haven’t heard any noise since I slept.
Sleep 为持续性动词,sleep的动作结束时,即“醒来”时,这句应译为“我醒后还未听到任何声音”。
John is now with his parents in New York, it is already three years since he was a teacher约翰现在和父母一起住在纽约,他不当教师已经三年了。
本文开始出现的那个句子就可以译为“自从我离开上海,就再也没有收到他的信。”这种译法常被人们误用,我们不妨再多举几个例子看看:
How long is it since you lived in Shanghai?你离开(没住在)上海多久了?
It is half a month since he was a League member.他退团(不当团员)半个月了。
It’s been quite some time since I was last in London我离开伦敦已很长时间了。
比较:He has written to me frequently since I was ill.自从我病愈以来,他屡次给我写信。(从句谓语为状态动词)
He has written to me frequently since I fell ill.自从我生病以来,他就屡次给我写信。(从句谓语为终止性动词)
二、若since引导的状语从句的谓语动词是终止性 的过去时 ,则从句表示的时间是“从动作开始的那一时刻起”。如:
He has studied very hard since he came to our school.自从他来到我们学校,他学习就非常努力。
We have been missing them since they left here自从他们离开这里,我们就一直很想念他们。
这是最常见的一种用法,此处不再多述。
三、若since引导的状语从句的谓语为持续性 动词的现在完成时 ,则表示动作和状态延续到现在(说话时刻),其表示的时间的起点应从动作发生之时算起。如:
I haven’t heard from him since he has lived there。
这里has lived表示动作的持续性,时间的起点应从:“开始居住”时算起。因此此句可理解为“自从他(开始)住在那儿起,我就一直没收到他的来信”。
Since we have owned a car, we have gone camping every year。自从我们自己有了汽车,我们每年都去野营。
试比较:1. Since I’ve been at this school, we have had three headmasters.自从我到这所学校,我们已换了三个校长了。
Since I was at this school, they have had three headmasters.自从我离开这所学校,他们已换了三个校长了。
2.He has never been to see me since I have been ill. 自从我生病以来,他从未来看过我。
He has never been to see me since I was ill. 自从我病愈以来,他从未来看过我。
由此可见,since引导的从句持续动词的一般过去时和现在完成时所表示的意思恰好相反。换言之,一般过去时持续动词以肯定的语法形式反映着否定的逻辑内容,而现在完成时的形式与内容是一致的。
至于It is +一段时间+since…的句型与It has been +一段时间+since…意思相同。前者是规范说法,后者是口语说法。
应注意的是,在这种结构中,since引导的从句绝对不能用否定式的谓语动词来表示否定意义,下面两句都错了:
It’s two months since you didn’t come to see me.
It is a long time since he didn’t study English.
正确的说法为:
It’s a long time since he studied English 他好久没学英语了。
You haven’t come to see me for two months. 你有两个月没来看我了。
1) since +过去一个时间点(如具体的年、月、日期、钟点、1980, last month, half past six)。
I have been here since 1989.
2) since +从句
Great changes have taken place since you left.
Considerable time has elapsed since we have been here.
3) since +一段时间+ ago
I have been here since five months ago.
4) It is +一段时间+ since从句
It is two years since I became a postgraduate student.

以下是小编为大家整理的as的用法总结,希望能帮助大家更好地认识as这个单词,提高英语水平。
as的释义:
adv.同样地,一样地; 例如
prep.作为,以…的身份; 如同
conj.像,像…一样; 由于; 同时,当…时;
尽管n.阿斯(古罗马重量单位,约373克)一、as作连词的用法
1. as...as的用法总结:
as...as意为"和……一样",表示同级的比较。使用时要注意第一个as为副词,第二个as为连词。其基本结构为:as+ adj./ adv. +as。例如:
(1)Your pen writes as smoothly as mine.你的钢笔书写起来和我的一样流畅。
(2)This film is as interesting as that one.这部电影和那部电影一样有趣。
其否定式为not as/so +adj./ adv. +as。例如:
This dictionary is not as/so useful as you think.这本字典不如你想象的那样有用。
若有修饰成分,如twice, three times, half, a quarter等,则须置于第一个as之前。例如:
Your bag is twice as expensive as mine.你的袋子比我的贵一倍。
几个关于as...as的常见句型:
(1)as...as usual/before
She looks as pretty as before.她看起来和以前一样漂亮。
(2)as...as possible
Please answer my question as soon as possible.请尽快回答我的问题。
(3)as long as... (引导条件状语从句)
It took us as long as three years to carry out the plan.我们花了长达三年的时间才完成这项计划。
(4)as far as
He walked as far as the railway station yesterday evening.昨天傍晚,他一直散步到火车站。
(5)as well as
She cooks as well as her mother does.她烧菜烧得跟她母亲一样好。
一些带有as...as结构的常见短语归纳:
as busy as a bee像蜜蜂一样忙碌
as light as a feather像羽毛一样轻
as soft as butter像黄油一样软
as easy as ABC像ABC一样容易
as deep as a well像井一样深
as rich as a Jew像犹太人一样富裕
2. as用作连词引导时间状语从句
as与when,while都是引导时间状语从句的从属连词,含义都是"当……的时候"。但它们有区别:用when时,从句的动作可以与主句的动作同时发生,也可以先于主句的动作发生;用while时,从句的动作为一过程,主句动作与从句动作同时进行或在从句动作过程中发生;用as时,主句和从句的动作同时发生,具有延续的含义。例如:
(1)He was watching TV while his mother was cooking.他母亲做饭时他在看电视。
(2)It was snowing when he arrived at the construction site.他到达工地时,天正在下雪。
(3) You will grow wiser as you grow older.你会随着年龄的增长而越来越聪明。
3. as用作连词引导原因状语从句
as,because,since都可以表示因果关系,连接原因状语从句,含义是"因为,由于",但它们有区别:because表示的语气最强;as一般放在句首,语气较弱,较口语化;since常常用在书面语中,表示多为对方已知的、或稍加分析便可得知的原因,有时可译作"既然"。例如:
(1) He will succeed because he is in earnest.他一定会成功,因为他很认真。
(2) Since you are so sure of it he”ll believe you.既然你对此如此有把握,他会相信你的。
(3) As rain has fallen, the air is cooler.因为下过雨,空气比较清爽。
4. as作连词引导让步状语从句
as与although (或though),however (或no matter how)等都可以引导让步状语从句,含义是"虽然,尽管",但它们有区别:although语气稍正式些,可放在句首,也可放在句中,主句中不能再用but,但可以用yet;as所表示的语气较强,引导的让步状语从句用倒装语序;however引导让步状语从句时,它的后面可跟形容词或副词,也要用倒装语序。例如:
(1) Although he is quite old, he still jogs every day.他虽然年纪相当大,仍然每天慢跑。
(2) Strange as it may seem, nobody was injured in the accident.这次意外虽然显得令人不可思议,却没有人受伤。
(3) However hard he may try, he will not attain his goal.无论他怎样努力也达不到目标。
二、as作关系代词的用法
关系代词as引导定语从句时,既可以单独使用,也可以与其他词连用,其用法要比that和which更为复杂。
1. as引导定语从句与其他词连用
①用于the same...as结构中
This is the same book as I read last week.这本书和我上周读的那本是一样的。
②用于such...as结构中
I don”t like such books as he recommends.我不喜欢他推荐的那些书。
③用于"so +adj. + a/an + n. (单数) + as "结构中
I am not so strong a man as I was.我已经没有从前那么强壮了。
2. as单独引导定语从句
as单独引导定语从句时,先行词可以是一个词,也可以是一个句子或短语。例如:
(1) She is late, as is often the case.她迟到了,这是经常的事。(先行词是整个主句)
(2) To shut your eyes to facts, as many of you do, is foolish.对事实视而不见--你们好多人都是如此的愚蠢。(先行词是不定式短语)
三、as作介词的用法
as作介词,意思是"作为","以……身份"。例如:
He came to China as a tourist five years ago.他五年前以游客的身份来过中国。
四、as作副词的用法
to the same degree or amount; equally "相同地","同样地"。例如:
They don”t have as many airplanes.他们没有同样多的飞机。

以下是小编为大家整理的as well as 用法总结,希望能帮助大家更好的认识as well as这个句型,提高英语水平。
as well as后接动词到底该用什么形式,这是一比较复杂的问题,归纳起来有以下几点值得注意:
1.as well as通常被视为介词,所以后接动词时,一般用动名词形式。如:
Smoking is dangerous,as well as making you smell bad.吸烟不仅使你身上有气味,而且危险。
He sings as well as playing the piano.他不但会弹钢琴,而且会唱歌。
As well as breaking his leg,he hurt his arm.他不但摔断了腿,而且还伤了胳膊。
She is a talented musician as well being a photographer.她不但是摄影师,而且还是个天才的音乐家。
注:as well as后接动词用动名词的情况主要见于主句谓语为简单时态(即一般现在时和一般过去时)的场合。
2.如果主句谓语为复合时态(即其中含有情态动词或助动词),则as well as后的动词通常要与情态动词或助动词后的动词形式保持一致。如:
Students shouId pursue their own interests.as Wen as do their school work.学生不仅应该要做好家庭作业,而且还要有自己的兴趣。
I have to feed the horses as well as look after the children.我不但要照顾孩子们,而且还要喂那些马。
3.如果as Well as是连接两个不定式,则其后用不带to的不定式。如:
We cannot expect her to do the homework as wen as look after the chil.dren.我们不能指望她既做作业又照看孩子。
A museum should aim to entertain as well as educate.博物馆不仅要具有教育性还且还要具有娱乐性。
4.当as well as用于句首时,其后习惯上要接动名词。如:
As well as eating a seven-course meal,they drank three bottles of wine.除吃了一顿有七道菜的饭之外,他们还喝了三瓶酒。
As well as visiting Niagara Falls,we spent a day in Toronto.我们参观了尼亚加拉瀑布,而且还在多伦多玩了一天。
As well as walking,he likes fishing and shooting.他除散步之外还喜欢钓鱼和打猎。
As well as getting on everybody’s nerves.he’s got a habit of borrowingmoney and forgetting to pay it back.他使得人人都感到心烦,此外,他还有个习惯,就是借了钱就忘了还。
注:as well as有时也被视为准并列连词,后接的动词可以与主句谓语动词形式一致(但这种情形远不如用后接动名词普遍)。如:
He publishes as well as prints his own books.他不但印刷而且还出版自己的书。

以下是小编为大家整理的英语表语的用法总结,希望能帮助大家更好地掌握英语表语的用法,提高英语水平。
表语的功能是表述主语的特征、状态、身份等。它也可以说是一种主语补足语。它位于连系动词之后,与之构成所谓的系表结构。在系表结构中,连系动词只是形式上的谓语,而真正起谓语作用的是表语。可以用作表语的有名词、代词、数词、形容词、副词、不定式、动名词、分词、介词短语、从句等。
(1)Time is pressing. Let’s hurry up. 时间紧迫,我们得抓紧。
(2)The situation is inspiring. 形势令人鼓舞。
[拓展]英语中有些表示感觉的及物动词,其现在分词表示主动,即“令人有某种感觉”。现在分词与中心词之间构成逻辑上的主谓关系。这类词一般都可作表语。
(1)The story he told us was very amusing.
他给我们讲的故事很有趣。
(2)The noise is very frightening. 那声音很恐怖。
[归纳]这类动词有:amuse(有趣,给……娱乐),satisfy(满意),encourage(鼓励),disappoint(失望),inspire(鼓舞),frighten(吃惊),surprise(惊讶),bore(使厌烦),puzzle(使迷惑)等。
