did not=didn't
can not=can't
have='ve
has='s
have not=haven't
has not=hasn't
will='ll
will not=won't
shall not=shan't
第二点:将来完成进行时
将来完成进行时
形式
will/shall have been+现在分词用于第一人称,而 will have been+现在分词用于其他人称。
用法
正如将来完成时一样,它通常与一个以by开头的时间短语连用:
By the end of this year he’ll have been acting for thirty years.
到今年年底他当演员就满30年了。
将来完成进行时与将来完成时的关系和现在完成进行时与现在完成时的关系一样。即在以下情况下可以用将来完成进行时而不用将来完成时:
1、动作本身就是连续的:
By the end of the month he will have been living/working/studying here for ten years.
到了月底他在这里居住/工作/学习就满十年了。
2、一种经常进行的动作被表示为连续的动作:
By the end of this month he will have been training horses/climbing mountains for twenty years.
到了这个月底他驯马/登山就满20年了。
但是如果提到所驯马匹或所攀登的山峰的数目,或用任何方式把动作分割为一次又一次的动作,就必须用将来完成时:
By the end of the month he will have trained 600 horses/climbed 50 mountains.
到本月底,他驯服的马就有600匹/攀登的山峰就有50座了
第三点:过去完成进行时
过去完成进行时
表示一个动作从过去某时开始,一直延续到另一个过去时刻,到那个时刻,该动作可能刚刚终止,也有可能还在继续。
形式
had been + V-ing形式
用法
1、过去完成进行时所表示的动作与过去的时间的关系,可以用时间状语来表示,也可以通过上下文来表示。
例如:
By the end of last month they had been working here for about ten days. 到上个月为止,他们在这里工作大约有十天了。
She said that she had been listening to radio after school. 她说她放学后一直在听收音机。
2、过去完成时可以表示一个动作已经结束,但其结果仍然影响到过去的某一时刻。
例如:
It had been raining and the street was still wet. 天一直在下雨,街道仍然很湿。
3、像 work、study、stay、sing、teach等延续性动词与表示一段时间的时间状语连用时,用过去完成进行时可以表示一个动作一直延续到过去某一时刻,通常强调动作的持续性和不间断性。
例如:
She had been studying for two hours when her classmate came to visit her. 当她的同学来看她的时候,她学习有两个小时了。
4、过去完成进行时与过去进行时的区别:过去进行时主要表示过去某时的一个动作正在进行。例如:
I was writing a letter when she came to see me. 当她来看我时我正在写信。
I had been writing a letter for two hours by the time she came to see me. 当她来看我的时候,我已经写了两个小时的信了。
5、过去完成进行时与过去完成时的不同:过去完成时表示过去某时间前已经发生的动作或情况,这个过去的时间可以用by,before等介词短语或一个时间状语从句来表示;或者表示一个动作在另一个过去动作之前已经完成。例如:
They had just had breakfast when Tom came in. 汤姆来时,他们刚吃过早饭。
They had been having breakfast for ten minutes when Tom came in. 汤姆来时,他们已经吃了十分钟的早饭了。
第四点:现在完成进行时
现在完成进行的形式
I / we / they have been + 动词的现在分词
He / she / it has been + 动词的现在分词
现在完成进行的功用
1) 表示一个在过去开始而在最近刚刚结束的行动,如:
Ann is very tired. She has been working hard.
Why are you clothes so dirty? What have you been doing?
2) 表示一个从过去开始但仍在进行的行动,如:
It has been raining for two hours. (现在还在下)
Jack hasn’t been feeling very well recently.
3) 表示一个从过去开始延续到现在,可以包括现在在内的一个阶段内,重复发生的行动,如:
She has been playing tennis since she was eight.
4) 现在完成时强调动作行为的结果、影响,而现在完成进行时只强调动作行为本身,如:
Tom’s hands are very dirty. He has been repairing the car.
The car is going again now. Tom has repaired it.
注意:
现在完成时有否定结构、而现在完成进行时没有否定结构。
现在完成时态可表示做完的时期以及已有的经验、但现在完成进行时不可以。
现在完成进行时的否定结构
在当代英语中,现在完成进行时有时也可用否定结构。如:
Since that unfortunate accident last week, I haven’t been sleeping at all well. 自从上周发生了那次不幸事故之后,我一直睡得很不好.
He hasn’t been working for me and I haven’t has that much contact with him. 他并没有给我工作过,我和他没有过那许多接触。
否定句构成:
主语+has/have+not+been+现在分词
一般疑问句构成:
Have/has+主语+been+现在分词+其他
第五点:过去将来完成时
过去将来完成时
形式
should / would have done sth.
用法
1、 过去将来完成时表示在过去将来某一时间以前发生的动作,并往往会对过去将来某一时间产生影响。
I thought you'd have left by this time. 我想这会儿你已经走了。
He told them he would have finished it by 8 o'clock. 他告诉他们他会在8点以前干完。
I guessed that Helen would have told her something. 我猜海伦会告诉她一些情况的'。
2、 过去将来完成时还常用在虚拟语气中,表示与过去的事实相反。
第六点:过去将来进行时
过去将来进行时:表示就过去某一时间而言,将来某一时刻或某一段时间正在进行的动作,主要用宾语从句中,尤其多用于间接引语中。
基本用法:
用于间接引语:They said they would be coming.(他们说了他们将要来。)
用于定语从句:The new job he would be taking was raising racing horses.(他将要接受的新工作是养赛马。 )
作用:
1、过去将来进行时可以表示在过去某一时间之后即将进行的动作:
例如:He said he could not come because he would be having a meeting.(他说他不能来因为要开会。)
2、过去将来进行时表示在过去将来某一时间正在发生的动作:它常和表过去将来的时间状语连用,但上下文清楚时,时间状语亦可省略。和将来进行时一样,它也常表计划中的事,不表意愿或打算。它还有一个特点,即常用在宾语从句(尤其是间接引语)中。
例如:John told us that Mary would be coming next day.(约翰告诉我们玛丽第二天来。)
3、过去将来进行时有时也可用在其它从句中:
用在定语从句中:The new name he would be using was Jack Jones.(他将用的新名是杰克琼斯。)
用在状语从句中:He would pay the rest as he would be leaving France.(其余款项,他将在离开法国时付清。)
4、过去将来进行时也可用在独立句中:
例如:The car started. Ellen James would be driving off to the university.(车子发动了。埃伦詹姆斯要开车到大学去。)
英语语法知识点2
初中英语语法:在习惯上只用作定语的形容词
习惯上只用作定语的形容词
这里说的定语指的是位于名词前作定语(即前置定语),而不是位于名词后作定语(即不用作后置定语),如main 是定语形容词,可以说mainthings,但不能说something main,因为后置定语从本质上说相当于表语,即something main 从本质上说相当于somethingthat is main。下面是几类典型的定语形容词:
一、表示相对关系的形容词
former 以前的,从前的 latter 后期的,后半的
inner 内部的,里面的 outer 外部的,外面的
upper 上部的,上游的 lower 下部的,下游的
elder 年岁较大的 eldest 最年长的
indoor 室内的,屋内的 outdoor 室外的,屋外的
inside 里面的,内侧的 outside 外面的,外侧的
upstairs 楼上的 downstairs 楼下的
【注】inside, outside, downstairs, upstairs等既可用作形容词也可用作副词。用于形容词时,只用于名词前作定语;若用作副词,则可用作表语(或名词后作定语)。
二、表示强调意义的形容词
mere 仅仅的 very 极端的
outright 完全的 thorough 十足的
plain 完全的 complete 彻底的
pure 完全的 perfect 全然的
【注】若用于其他意义,有的可用作表语,如plain表示“明白的”、“普通的”等均可用作表语;perfect表示“完美的”、“完备的”、“准确的”等,也可用作表语。
三、表示度量的复合形容词
three-year-old 3岁大的 120-page 120页的
five-year 5年的
若用作表语或后置定语,则不用连字符:
She has a five-year-old son. 她有一个5岁的儿子。
Her son is five years old. 她的儿子五岁。
She has a son five years old. 她有一个5岁的孩子。
初中必备英语语法:八种宾语从句不省略that
引导宾语从句的that在下列情况下一般不省略:
1. 宾语从句前有插入语。如:
We hope, on the contrary, that he will stay at home with us.恰恰相反,我们希望他和我们呆在家里。
2. 有间接宾语时。如:
He told me that he was leaving for Japan. 他告诉我他要去日本。
3. that在与之并列的另一个宾语从句之后。如:
He said (that) the book was very interesting and that(不省略) all the childrenlike to read it.他说那本书很有趣,所有小孩都喜欢读。
4. 在“it(形式宾语)+补语”之后时。如:
I think it necessary that he should stay here. 我们认为他有必要留在这里。
5. that从句单独回答问题时。如:
—What did he hear? 他听说了什么事?
—That Kate had passed the exam. (他听说)凯特考试及格了。
6. 在except等介词后。如:
He has no special fault except that he smokes toomuch.他除了抽烟太多之外,没有什么特别的毛病。
7. 位于句首时。如:
That our team will win, I believe. 我相信我们队会赢。
8. 在较为正式或不常用的动词(如reply, object)后。如:
He replied that he disagreed. 他回答说他不同意。
初中英语语法:if与whether的区别
1. 引导主语从句并在句首时不用if。如:
Whether we go there is not decided. 我们是否去那里还没决定。
2. 引导表语从句时不用if。如:
The question is whether we can get there on time. 问题是我们能否按时到达那里。
3. 引导同位语从句时不用if。如:
He asked me the question whether the work was worth doing.他问我这个问题,那项工作是否值得做。
4. 在介词后引导宾语从句不用if。如:
I’m thinking about whether we’ll have a meeting. 我在考虑我们是否要开个会。
5. 直接与not连用时不用if。如:
I don’t know whether or not you will go. 我不知道你是否去。
6. 宾语从句置于句首时不用if。如:
Whether you have met George before, I can’t remember. 我不记得你以前是否见过乔治。
7. 在discuss等之后时不用if。如:
We’re discussing whether we’ll go on a picnic. 我们在讨论是否要去野餐。
8. 当用if会引起歧义时不用if。如:
Please let me know whether you are busy.请告诉我你是否忙。(若用if,还可理解为“如果你很忙,你就告诉我。”
;Ⅱ 英语语法知识点整理
英语语法知识:It be time +(that)从句
在英语里,“It be time +(that)从句”是一个较为常用的句型,它表示“该做……的时候了”的意思。该句型属于主从复合句的一种;其主句部分为"It be time",从句部分的连词that可以省略。以下从三个方面简要谈谈这一句型。
一、time前面的修饰语
句型“It be time +(that)从句”通常暗示“有点迟了”,为了强调这一含义,可以在time的前面加形容词high.例如:
It's high time we started.
It is high time that more women ran the arts.
为了使语气得到进一步的加强,还可以在high的前面加certainly, more than等副词或词组:
It is certainly high time that we ordered dinner.
形容词full也可以加在time的前面,用来加强语气。例如:
It's full time you had a nice day.
It is full time that boy went to herding.
time前面还可以加about,这时句型所表达的意思是“早该……”。例如:
It's about time we started.
It's about time I settled down.
上面两例中的about可以用getting来代替,句意不变;这可以视为句型“It be time +(that)从句”的一种变体。
二、从句中的动词形式
在“(that)从句”中,动词形式通常是一般过去时。这是一种奇特而有趣的语言现象,即用假设的过去时来代替实际的将来时。从英语史的角度来看,从句中的动词形式用过去时原是属虚拟语气;但从语言发展的观点来看,目前这种动词形式视为陈述语气比较合适。
着名语言学家夸克(R. Quirk)教授等人在1985年出版的《英语语法大全》一书中认为,“(that)从句”的动词形式一定要用“假设的`过去时”。他们举了一例:It's time I was in bed.其实,动词形式除常用过去时外,也可以用其他时态和语态(用何种形式应视情况而定)。正如着名语言学家周海中教授在1988年发表的《探讨“It be time (that)…”句型》一文中所言:在现代英语里,“(that)从句”中的动词形式一般用过去时,这是基本规则;有时也可以用其他的动词形式,但应视为特殊用法。他在其文中列举了大量实例,用于论证和说明。
1.用were型虚拟语气。例如:
It's high time I were hence. (W. Shakespeare)
It's time I were gone. (A. Tennyson)
由于英语的发展,虚拟语气与陈述语气之间的区别正在逐渐消失。基于这种情况,虚拟语气的were也正在逐渐地代替陈述语气的was.
2.用be型虚拟语气。例如:
You reckon I be found anywhere with him, time he start belle ring. (W. Faulkner)
It is time that more of the research dollars now devoted to cure be diverted to finding new and more humane ways of curing that will make a cancer patient's remaining years happier, more comfortable, and more proctive. (Science, 1984, Vol. 5, No.7)
动词形式用be型虚拟语气是古英语的用法。目前,这一用法在英国英语中已“日薄西山”,而在美国英语中却有“东山再起”之势,但主要见于正式文体。
3.借助情态动词should
It's time this heart should be unmoved. (G. Byron)
It may be time that I should meet with some misfortune; but I hope it is not this. (C. Dickens)
上面用法主要见于文学作品,尤其是英国人写的。
4.用过去进行时。例如:
It's time we were leaving. (H. Maclnnes)
It's time we were getting home. (E. O'Neil)
上面用法通常是一些表示位置转移的动作动词。
5.用一般现在时。例如:
It is high time that the U. S. realizes it cannot continue to hide its head in the sand, for the sand has started to blow. (Newsweek, Oct. 15, 1979)
“It is time that the burden of Reaganomics is shared by those in the upper-income groups,” 0'Neill declared. (Time, Jun. 20, 1983)
上面用法主要见于美国英语,尤其在新闻文体里。这是一种值得关注的语言现象。
6.用完成时。例如:
It's time that rection in force has finally hit the federal government also. (U. S. News and World Report, Mar. 15, 1982)
Fooleries! Pshaw! It's time you'd done with fooleries. (G. Eliot)
上面用法也是一种值得关注的语言现象。
三、句型中的省略现象
在口语中,可以把句型“It be time +(that)从句”中的"It be"省略。例如:
High time we left. (J. Linsay)
Time we were going. (M. Hammonds)
在一定的上下语境中,也可以把句型中的“(that)从句”省略。例如:
This program goes in that direction, and I believe it's time. (T. Wicker)
在特定的语境里,甚至还可以把句型中的"It be"和“(that)从句”都省掉,意义仍然是显豁的;不过,这时time前面要用high来修饰,其后面常跟副词too,该词只是用来加强语气,并无具体意义。例如:
He's gone back to work.—— High time, too! (Longman Dictionary of English Idioms)
顺带一提,句型“It be the +序数词+ time +(that)从句”与句型“It be time +(that)从句”在结构上有点相似,但它们在句意上是完全不同的。前者也是主从复合句,当其主句的be用一般现在时,从句的动词形式通常为现在完成时,it可以用this来代替;当其主句的be用一般过去时,从句的动词形式通常为过去完成时,it可以用that 来代替。例如:
It/This is the first time (that) I have seen him.
It/That was the third time (that) I had been there.
Ⅲ 英语简单语法知识点
英语语法是针对英语语言进行研究后,系统地总结归纳出来的一系列语言规则。下面是我为你收集整理的英语简单语法知识点,一起来看看吧。

英语简单语法知识点【2】
一、词法
1、名词
A)、名词的数
我们知道名词可以分为可数名词和不可数名词,而不可数名词它没有复数形式,但可数名词却有单数和复数之分,复数的构成如下:
一)在后面加s。如:fathers, books, Americans, Germans,apples, bananas
二)x,sh, ch, s, tch后加es。如:boxes,glasses, dresses, watches, wishes, faxes

九)合成的复数一般只加主要名词,多数为后一个单词。如:action movie-action movies, pen pal-pen pals; 但如果是由man或woman所组成的合成词的复数则同时为复数。如:man doctor-men doctors, woman teacher-women teachers
十)有的单复数意思不同。如:fish鱼 fishes鱼的种类,paper纸 papers报纸,卷子,论文, work工作 works作品,工厂, glass玻璃glasses玻璃杯,眼镜,orange桔子水 oranges橙子, light光线lights灯, people人 peoples民族,time时间 times时代, 次数, chicken 鸡肉chickens小鸡
十一) 单个字母的复数可以有两种形式直接加s或’s。如:Is (I’s), Ks (K’s)。但如是缩略词则只加s。如:IDs, VCDs, SARs
十二) 特殊形式的有:child-children, man-men, woman-women, foot-feet, mouse-mice,policeman-policemen, Englishman-Englishmen
B)名词的格
当我们要表示某人的什么东西或人时,我们就要使用所有格形式。构成如下:
一)单数在后面加’s。如:brother’s, Mike’s, teacher’s
二)复数以s结尾的直接在s后加’,如果不是以s结尾的与单数一样处理。如:Teachers’ Day教师节,classmates’; Children’s Day六一节, Women’s Day三八节
三)由and并列的名词所有时,如果是共同所有同一人或物时,只加最后一个’s,但分别拥有时却分别按单数形式处理。如:Mike and Ben’s room迈克和本的房间(共住一间),Mike’s and Ben’s rooms迈克和本的房间(各自的房间)

he him his his himself
it it its its this that itself
复数 they them their theirs these thosethemselves
3、动词
A)第三人称单数
当动词是第三人称单数时,动词应该像名词的单数变动词那样加s,如下:

一种是以一般疑问句的结构形式为基础,只是在语调上有所区别。
例如:Would you like coffee or tea?
这一类选择疑问句通常都是在前一个供选择的答案用低升调,后一个用降调;如果有两个以上供选择的答案,则在最后一个用降调,其余都用低升调。
例如:
Would you like a gin,or a whisky,or a `beer?
你是要喝杜松子酒,还是威士忌酒,还是啤酒?
这种语调上的特征往往是区别选择疑问句和一般疑问句的重要标志。试比较:
Shall we leave at six or `seven?
我们是 6 点动身还是 7点动身?
Shall we leave at six or seven?
我们在6,7点钟动身好吗?
上述第一例是选择疑问句,其答案只能是两者之一。
We shall leave at six/seven.我们将在6点/7点动身。
上述第二例是一般疑问句,它的答案只是 yes/no,而且并不肯定是6点或7点,甚至可能既不是6点,也不是7点:
Yes,we shall leave at six or seven.是的,我们将在 6, 7点钟动身。
No.We must leave earlier.不。我们必须早点动身。
另一种选择疑问句是以特殊疑问句的结构形式为基础的,也是在语调上有所区别。
例如:Which vase shall I use, the short one or the tall one ? The tall one.
在选择疑问句中的冠词用法。
Is she a housewife or a nurse?(她是一个家庭主妇还是护士?)
其中,or后的不定冠词a/an 不能省略。
英语简单语法知识点:特殊疑问句
特殊疑问句:以特殊疑问词开头,对句中某一成分提问的句子。
常用的疑问词有:what who whose which when where how why等。
可先分为3种:
疑问代词:what,who,which,whose,whom
疑问副词:when,where,why,how
疑问形容词:what(which,whose)+名词
特殊疑问句有两种语序
1.如疑问词作主语或主语的定语,即对主语或主语的定语提问,其语序是陈述句的语序:
疑问词(+主语)+谓语动词+其他成分。
如:Who is singing in the room﹖ whose bike is broken﹖
2.如疑问词作其他成分,即对其他成分提问,其语序是:疑问词+一般疑问句语序?如:What class are you in﹖
What does she look like﹖
Where are you from﹖
What time does he get up every morning﹖
How do you know﹖
注意:
1.回答特殊疑问句时,不能用yes / no,即问什么答什么,尤其是简略回答。如:
Who is from Canada﹖ Helen (is).
Where's the restaurant﹖ Near the station.
Why do you like koalas﹖ Because they are cute.
2.特殊疑问句一般读降调(↓)。
特殊疑问词
Who谁——Whose谁的(加se)
Why为什么
When什么时候
Where在哪里
Which哪一个
What什么 ( What time什么时间 What colour什么颜色)
How怎么样
How many多少{数量}
How much多少钱{价格},
多少(对不可数名词进行提问)
How long多长
How often多少次
How big多大
How heavy多重{重量}
Ⅳ 英语语法知识点归纳有哪些
英语语法知识点归纳有如下:
1、be(是)动词的用法:am接I;is接第三人称单数,即除you、I外;are接表示多个人或事物,即复数。(我是am,你是are,is连接它、她、他,单数is,复数are)。
2、not是表示否定的词:不是的表达,am not,is not(isn’t),are not(aren’t)。
3、“一个”和“几个”的问题:“一个”是a+名词;“多个”是名词后面加s。
4、以元音开头(如O、E等),前面的冠词用an。
5、及物动词与不及物动词的区别:及物动词后面接宾语;而不及物动词后面不接宾语。如I like ice cream ,It hurts。
6、主语是he、she、it和单数名词时,动词要发生第三人称的变化,即加s。
7、否定的用法:在动词之前加do not或does not。I、You和复数名词做主语时,否定就用do not;凡是单数名称和he、she、it做主语,否定就用does not。
8、my(我的)、your(你的)、his(他的)、her(她的)、their(他们的)、our(我们的)、its(它的)+名词,如my love,your love 。

(1)“as +形容词或副词原级+as+被比较对象”结构。例句:He studies as hard as you. 他像你一样学习努力。
(2)在否定句或疑问句中可用not so…as…. 例句:He can notrun so/as fast as you. 他没你跑得快。
2.only引导的倒装句型:only +状语(或状语从句)位于句首时,句子部分倒装。

9.If虚拟条件句
3.英语语法解析
1.连词that, if, whether,连接代词what, which, who, whom, whose以及连接副词how, when, why, where可用来引导名词从句,充当主语、表语、宾语等。非正式文体中的宾语从句常省略that:
I think (that) he’ll be back in an hour. 我认为他一小时后就会回来。
Who they are doesn’t matter much. 他们是谁没什么大关系。
Can you tell me where he is? 你能告诉我他在哪儿吗?
He asked me if/whether I knew John. 他问我是否认识约翰。
此外,that, which, who, whom, whose, when, why, where等还可以引导定语从句。
2.连词when, while, before, after, till/until, since, as soon as等引导时间状语从句:
She said hello to me when she saw me. 她看到我的时候,和我打了招呼。
I’ll wait here until you come back. 我将在这里等你回来。
3.连词if, unless引导条件状语从句;because, as, since引导原因状语从句:
I’ll help her if she asks me to. 如果她要求我,我就帮助她。
I won’t help her unless she asks me to. 除非她要求我,否则我不会帮她。
He didn’t come because he was ill. 因为他病了,所以没来。
As he hasn’t appeared yet, we shall start without him. 既然他还没有出现,我们就先开始吧。
Since everybody is here, let’s begin. 既然大家都到了,咱们就开始吧。
4.连词in order than, so that引导目的状语从句;so … that …引导结果状语从句:
I locked the door in order that we might continue our discussions undisturbed. (=I locked the door in order to continue our discussions undisturbed.) 我把门锁上了,以便我们可以继续讨论而不受打扰。
The car ran so fast that I couldn’t see who was in it. 汽车跑得那么快,我没看清谁坐在里面。
5.连词than, as…as…, not as/so…as…用来引导比较状语从句:
He is better ecated than his brother. 他比他兄弟受的 教育 好。
He is as well ecated as his brother. 他和他兄弟受的教育一样好。
He is not as/so well ecated as his brother. 他没有他兄弟受的教育好。
6.连词although, though 引导让步状语从句;where, wherever 引导地点状语从句:
I’ll go wherever you go. 不管你去哪儿,我就去那儿。
Stay where you are! 原地别动!
Though/Although she is rich, she’s not happy. 尽管她富有,但她并不幸福。
一般来说,连词性质的连接词连接两个分句或引导一个从句,两个分句或主从复合句之间用逗号连接。
二、副词性连接词
副词性质的连接词不能象连词一样分句或主从复合句之间用逗号连接。也就是说它们不能连接两个分句或引导从句。它们引导的句子与前面的句子之间要用分号或句号,而它们与引导的句子之间往往用逗号。副词性质的连接词在写作中常常使用,主要分为以下几类:
1.表示顺序的,如first, in the first place, then, finally, in the end等等。尤其要注意then. 如:
误:He graated from college in 2003, then he found a job.
正:He graated from college in 2003, and then he found a job.
He graated from college in 2003. Then he found a job.
2.表示递进关系的,如in addition, what is more, furthermore, moreover等。注意in addition 与in addition to 的区别:in addition 是副词性质;而in addition to 是介词性质,后面必须接宾语。
3.表示转折关系的,如however, nevertheless, nonetheless, on the contrary, in contrast, 等等。要注意不要把however 当成连词。

2.why do we say language is arbitrary?
Language is arbitrary in the sense that there is no intrinsic connection between the sounds that people use and the objects to which these sounds refer.
The fact that different languages have different words for the same object is a good illustration of the arbitrary nature of language, it’s only our tacit agreement of utterance and concept at work and not any innate relationship bound up in the utterance.
A typical example to illustrate the ‘arbitrariness’ of language is ‘a rose by any other name would smell as sweet’.

Modern linguistics is mainly synchronic, focusing on the present-day language. unless the various states of a language are successfully studied, it will not be possible to describe language from a diachronic point of view.
现代语言学主要是共时性的,重点研究现代语言。除非对语言的各种状态都进行成功的研究,否则很难从历时性角度对语言进行描述。
5.which enjoys priority in modern linguistics, speech or writings?
Speech enjoys for the following reasons:
⑴Speech precedes writing in terms of evolution.
⑵A large amount of communication is carried out in speech than in writing.
⑶speech is the form in which infants acquire their native language.

Ⅷ 英语语法知识点有哪些
1、名词
名词(noun)是指人或事物的名称。
名词一般分为专有名词(proper noun)和普通名词(common noun)。专有名词是个别的人、事物、地点、团体、机构等专有的名称,首字母通常大写。

Ⅸ 英语语法有哪些知识点归纳
英语语法是针对英语语言的语法进行的研究,指英语中语言的结构规律。包括词法和句法。英语的语法既可以是规范性的,也可以是描述性的。
首先词类:冠词,代词,动词(谓语和非谓语),形容词,副词。
(非谓语主要是doing,to do,done)
其次句型(主谓宾格式)
最后从句:名词性从句(包括主语从句,宾语从句,同位语从句(重要)),状语从句(表示时间,目的,方式,地点,条件等),让步状语从句(重要),倒装句(重要),定语从句(限制性与非限制性) 注意不同从句的引导词或先行词 语法书中都有。
(9)英语常用语言知识点扩展阅读:
情态动词本身就具有一定的词义,但要与动词原形以及其被动语态一起使用,给谓语动词增添情态色彩,表示说话人对有关行为或事物的态度和看法,认为其可能、应该或必要等。情态动词后面加动词原形。
情态动词不能表示正在发生或已经发生的事情,只表示期待或估计某事的发生。
情态动词除ought 和have外,后面只能接不带to的不定式。
情态动词不随人称的变化而变化,即情态动词的第三人称单数不加-s。情态动词不受任何时态影响即不加三单。
情态动词没有非谓语形式,即没有不定式、分词等形式。
