【语法难点精析之besides,but,except,exept for,excepting,apart from的区别】

（１）besides与except 前者表示＂除．．．以外，还有．．．＂；后者表示＂从整体中除去．．．＂ 这个大家都知道，就不举例子了．

（２）except与except for a．除去的和非除去的是同类事物，用except eg：

All the essays are well written except Nelson's.Nelson的文章（除去的）和All the essays（非除去的）是同类事物，所以用except． b．除去的和非除去的不是同类事物，用except for，并且从语气上通常表示遗憾．

无忧考网www.xiexiebang.com here every day,always excepting the youngest.（５）but与except同义，但but多用在every，any，no等和由这些词构成的复合词如everything，anywhere，nobody等词以后及all，none之后 eg：

The children go to school everyday but Sunday.They are all gone but me.You can get the book anywhere but here.There is no one but me.Who but George would do such a thing? 【语法难点之too...to 结构表示肯定含义的情况】（连载中）【too...to 结构表示肯定含义的情况】

我们知道too...to结构一般表示否定含义,意为“太...以致于不能” eg:He is too old to work.无忧考网www.51Test.net 但too...to在下列情况下却表示肯定含义: ⑴当too前或to前有否定词构成双重否定时.eg:English is not too difficult to learn.英语并不太难学.He is too wise not to see that.他很聪明,不会不懂这一点.⑵当too后是glad,pleased,happy,delighted,satisfied,ready,willing,kind,apt,good,true,easy,near,careful,well,early,delicious,eager,anxious等形容词或副词时.eg:They are too anxious to leave.他们急于离开.He is too ready to help others.他总是乐于助人.与这些词连用时,too前还常加上only,all,but,just,simply等副词,意思不变,因为这些词加上too后与very同义.eg:I'm only too glad to see you.见到你非常高兴.They are but too pleased to hear the news.他们听到这个消息,非常高兴.⑶与cannot连用时.eg:You cannot be too careful(=You can never be careful enough)to do your homework.你做作业越仔细越好(=无论怎样仔细也不过分).⑷当不定式在句中作定语或真正的主语时.eg:There are too many problems to be solved.有很多问题有待解决.It is too much to say that he is a fool.【语法难点精析之every表示”每隔“的用法】

无忧考网www.51Test.net ⑴"every other+单数名词” 意思是“每隔一。。”

如：every other day 每隔一天 every other tree 每隔一棵树

⑵“every+基数词+复数名词”或“every+序数词+单数名词” 意思是“每隔。。”（较英语数词少一个）

如：every three days=every third day 每隔两天（或者译为每三天）因此every two days=every other day 每隔一天（或者译为每两天）

⑶“every few+复数名词” 意思是“每隔几。。”

如：every few days（每隔几天）

【语法难点精析之alive、live、living和lively的用法】

⑴ lively 有“活泼的、快活的、生动的”等意思，可以指人或物，可作定语或标语；但它没有“活着的”意思，而其他三个都有。如：

Young children are usually lively.小孩子们通常是活泼的。He told a very lively story.他讲了一个生动的故事。

⑵alive、live、living都有“活的、有生命的”意思，与dead意义相反。但live通常只作前置定语，且一般用于动物；alive、living不仅可作定语（alive只能置于名词后；living一般置于名词前，也可置于名词后），也可以作表语。如：

This is a live(=living)fish.(=This is a fish alive.)这是一条活鱼。（指动物，且作定语时，三者均可用）Who's the greatest man alive(=living man)? 谁是当今最伟大的人物？（指人，不能用live）The fish is still alive(=living)那条鱼还活着。（指动物作表语时不能用live）。

无忧考网www.51Test.net ⑶living主要指在某个时候是活着的，而alive指本来有死的可能，但仍活着的。而且，作主语补足语或宾语补足语时，只能用alive；作比喻义（如“活像。。”、“活生生的”等）解时，要用living。如：

The enemy officer was caught alive.(作主语补足语，不用living）那位敌方军官被活捉了。

We found the snake alive.(作宾语补足语，不用living）He is the living image of his father.(比喻义，不用alive）他活象他父亲。

第三篇：英语语法疑点难点总结

英语语法疑点难点总结

（七年级上半期）

一、have和has的区别及用法：

都表示“有”

用于主语是非第三人称单数，如： we/ they/ you / I 等如： I have a pen； have前面一般是第一、二人称或者是复数，例如：We，I，You，Mary and John，Parents，Books；

用在主语是第三人称单数时, 如 she/ he / it如;My mother has been to the Great Wall three times；has则是相反的，一般是第三人称或者单数，例如：A monkey，The girl~~这是最基础的不同点~~

二、their和they them的区别及用法 是所有格（物主代词）意思是：他们的 通常作为主语 意思是： 他们是宾语 跟在动词后面 意思是：他们

三、可数名词的单复数规则

可数名词都有单数和复数之分。

A: 规则的可数名词的复数变化规则：

1.一般情况加 s ： book--books mouth---mouths house---houses girl---girls

2.以 s、sh、ch、x结尾的加 es ： class---classes box----boxes match----matches

3.辅音字母 + y结尾的变 y为 i加es： city---cities

country----countries party----parties factory----factories

4.以 o 结尾的词 +es的只有以下词 ：heroes Negroes tomatoes potatoes zeroes/zeros以 o 结尾并且词尾有两个元音字母 +s radios, zoos, bamboos ,(pianos ,kilos photos)5.以f，fe 结尾的 变f或fe为v +es ：thief wife life knife wolf half leaf shelfThe thief’s wife killed three wolves with some leaves and knives in half of her life.四、可数名词与不可数名词

普通名词所表示的人或事物是可以按个数计算的，这类名词叫可数名词。可数名词分为个体名词(表示某类人或事物中的个体，如worker, farmer, desk, factory等)和集体名词(表示作为一个整体来看的一群人或一些事物，如people, family 等)。如果普通名词所表示的事物是不能按个数来计算的，这类名词就叫不可数名词。不可数名词分为物质名词(表示无法分为个体的物质，如meat, rice, water, milk, orange 等)和抽象名词(表示动作、状态、情况、品质等抽象概念，如work, homework, time, health, friendship等)。

二、关于可数名词

可数名词有单数和复数两种形式。指一个人或一件事物时，用单数形式；指两个或多个人或事物时用复数形式。名词由单数形式变成复数形式的规则如下：

1.一般的名词词尾直接加-s。如：

book → books room → rooms

house → houses day → days

2.以s, ss, ch, sh, x 结尾的名词，在词尾加-es。如：bus → buses glass → glasses

watch → watches

dish → dishes box → boxes

3.以“辅音字母+y”结尾的名词，要先将y改为i再加-es。如：city → cities body → bodies

factory → factories等等。

4.以f 或fe 结尾的名词，要将f或fe改为v再加-es。如：half → halves leaf → leaves

knife → knives wife → wives

5.特例 [悄悄话：特例常常考，要记住。]

① child → children

② man → men woman → women

policeman → policemen

(规律：man → men)

③ tomato → tomatoes

potato → potatoes

[悄悄话： 初中英语以o 结尾的名词变复数时只有这两个词加-es，其余的当然加-s喽！如：photo → photos ]

④ foot → feet tooth → teeth

[悄悄话： oo变成ee。]

⑤ sheep, Chinese, Japanese单、复数同形 [悄悄话：变复数时词形不变。]

⑥ people单数形式表示复数意义，要求谓语动词用复数； people的复数形式peoples通常指“多个民族”。

三、关于不可数名词

1.不可数名词没有复数，当它作句子的主语时，谓语动词要用单数形式。

如：The food is very fresh.食品很新鲜。

2.有的不可数名词也可以作可数名词，有复数形式，但他们的意义往往发生变化。

如：water(水)→ waters(水域)

orange(橘汁)→ oranges(橘子)

3.很多的不可数名词表示泛指时为不可数，表示种类时就可数，但意义大多不发生变化。

如：fruit → fruits food → foods

fish → fishes hair → hairs

四、名词可数不可数“六注意”

1、可数名词是可以用来计数的名词。可数名词有单数和复数形式。如：desk-desks, apple-apples等。不可数名词是不可以直接用来计数的名词。不可数名词没有复数形式，只有单数形式。如：some bread，a little milk等。

2、单数可数名词表示泛指时，前面要用不定冠词a(an)，表示特

指时，前面要用定冠词the;而不可数名词前不能用a(an)修饰，表示特指时，前面一定要用定冠词the。如：

He is a factory worker.他是一名工人。

No one can see air.没有人能看见空气。

3、可数名词和不可数名词前都可以用some, any, a lot of, lots of 等来修饰，表示“一些，许多”。如：

There are some oranges on the desk.桌子上有一些桔子。There is a lot of water in the bottle.瓶里有许多水。

4、可数名词前可用具体的数词来表示具体的数量。如：two apples, four books等。不可数名词前通常用“单位词+of”来表示数量。如： a piece of paper, three pieces of paper等。

5、可数名词作主语时，谓语动词的单复数与主语的单复数保持一致。如：

This picture is very beautiful.这幅画很美。

不可数名词作主语时，谓语动词要用单数形式，但是不可数名词前有复数“单位词”时，谓语动词要用复数形式。如：

There are two cups of tea on the table.桌上有两杯茶。

6、对可数名词前的修饰语提问用how many;对不可数名词前的修饰语提问用how much。如：

How many apples are there in the box?盒子里有多少个苹果？How much tea is there in the cup?杯里有多少茶水？

注意：对不可数名词前的“单位词”的修饰语提问时，疑问词用how

many。如：

How many pieces of bread are there on the plate?盘子里有多少片面包？

第一章 名词性从句

在句子中起名词作用的句子叫名词性从句(Noun Clauses）。名词性从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能，名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。

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。被强调部分指人时也可用who/whom。例如：

a)It is a pity that you didn’t go to see the film.你不去看那场电影真可惜。

b)It doesn’t interest me whether you succeed or not.我对你成功与否不感兴趣。

c)It is in the morning that the murder took place.谋杀案是在早上发生的。（强调句型）

d)It is John that broke the window.是John打碎的窗户。（强调句型）

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„

It appears that„

似乎„(4)It ＋ 过去分词 ＋ 从句

It is reported that„

据报道„

It has been proved that„

已证实„

It is said that„

据说„

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：

正确表达：It is said that President Jiang will visit our school next week.错误表达：That President Jiang will visit our school next week is said.（3）It happens/occurs„结构中的主语从句不可提前。例如：

正确表达：It occurred to him that he failed in the examination.错误表达：That he failed in the examination occurred to him.（4）It doesn’t matter how/whether „结构中的主语从句不可提前。例如：

正确表达：It doesn’t matter whether he is wrong or not.错误表达：Whether he is wrong or not doesn’t matter.（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：

正确表达：Is it likely that it will rain in the evening?

错误表达：Is that will rain in the evening likely?

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：

a)What you said yesterday is right.b)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.我听说他参军了。

(2)由what, whether(if)引导的宾语从句，例如：

a)She did not know what had happened.她不知道发生了什么。

b)I wonder whether you can change this note for me.我想知道你是否能帮我改一下笔记。

(3)动词＋间接宾语＋宾语从句。例如：

She told me that she would accept my invitation.她对我说她会接受我的邀请。

2.作介词的宾语，例如：

Our success depends upon how well we can cooperate with one another.我们的成功取决于我们之间的合作。

3.作形容词的宾语，例如：

I am afraid(that)I’ve made a mistake.我恐怕我已经犯了一个错误。

注意：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.我听说她下个朋就会结婚了。

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。如：

正确表达：I admire their winning the match.错误表达：I admire that they won the match.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：

正确表达：He impressed the manager as an honest man.错误表达：He impressed the manager that he was an honest man.7.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。

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）

第三章 高中英语语法中的省略现象

在英语语言中，为了使语言简洁明了，重点突出或上下文紧密相连，可以省去某些句子成分而保持句子愿意不变，这种语言现象称之为省略。现就英语中的种种省略现象分析如下：

一、并列复合句中的省略

在并列句中后边的分句可以省略与前边分句中相同的成分。如：

a)The boy picked up a coin in the road and(the boy)handed it to a policeman.这个男孩在马路上拾起一枚硬币并把他交给了警察。

b)Your advice made me happy but(your advice made)Tom angry.你的建议使我高兴但使汤姆生气。

c)Tom must have been playing basketball and Mary(must have been)doing her homework.汤姆肯定一直在打篮球，玛丽一直在写作业。

d)Gao Xiumin was born in 1959 and Fu Biao(was born)in 1963.高秀敏出生于1959年，傅彪出生于1963年。

二、主从复合句中的省略

1．状语从句中的省略

一般说来省略现象多出现在下列五种状语从句中：由 when ,while ,as ,before, after , till, until, once等引导的时间状语从句；由whether ,if , unless 等引导的条件状语从句；由though , although ,even if ,whatever等引导的让步状语从句；由 as ,than 等引导的比较状语从句；由as, as if , as though 等引导的方式状语从句。上述状语从句在省略时应遵循下面原则：

1)当状语从句的主语与主句的主语一致时，可以省略状语从句的主语和系动词be，这时从句中可出现如下结构：(1)连词（as, as if , once）+ 名词;(2)连词（though, whether , when）+形容词；(3)连词(whether, as if ,while)+介词短语；(4)连词(when , while , though)+ 现在分词；(5)连词(when ,if ,even if ,unless ,once ,until, than , as)+ 过去分词；(6)连词(as if ,as though)+ 不定式。如：

a)Once(he was)a worker ,Pang Long now becomes a famous singer.庞龙曾经是个工 人，现在变成一位著名的歌手。

b)Work hard when(you are)young ,or you'll regret.趁年轻要努力学习，要不然你会后悔的。

c)He looked everywhere as if(he was)in search of something.他到处看似乎在找什么东西。d)While(he was)holding talks with President Hu Jintao ,US President George W.Bush thanked China for its important role in the Six-Party Talks.美国总统布什在与胡锦涛主席会谈时，感谢中国在六方会谈中起的重要作用。

e)The exhibition is more interesting than(it was)expected.这次展览比被预料的有趣的多。

f)Olympic gold medallist hurdler Liu Xiang opened his lips as if(he were)to speak。奥林匹克金牌获得者跨栏运动员刘翔张开嘴好像要说什么。注意：

1)当从句的主语和主句的宾语一致时，间或也有这样的省略,如： Her father told her to be careful when(she was)crossing the street.当她过马路时父亲告诉她要当心。

2)当从句的主语是 it，谓语动词中又含有系动词be 时，可以把it和系动词be一起省略。此时构成连词(if , unless ,when , whenever)+形容词的结构。如：

Unless(it is)necessary ,you'd better not refer to the dictionary.如果没有必要，你最好不要查字典。

2．定语从句中的省略

1）一般说来，在限制性定语从句中，作宾语的关系代词 that ,which , whom 可以省略；如：

Is this reason(that)he explained at the meeting for his carelessness in his work?这就是他在会上解释他工作中粗心的原因吗？（2002上海春季）

而在非限制性定语从句中作宾语的关系代词 which , whom 不可以省略。试比较：

Tom(whom)you saw yesterday fell ill.(whom可以省)你昨天见到的汤姆病倒了。

Tom , whom you saw yesterday ,fell ill.(whom不可以省)汤姆病倒了，你昨天见到他了。

2）在口语和非正式用语中，关系副词when ,where , 和 why 经常用that 来代替，甚至还可省略。如：

a)This is the first time(when/that)he had trouble with the boss.这是他第一次麻烦老板。

b)He wants to find a good place(where/that)we can have a picnic during the “golden week ”holiday.他想找一个能在黄金周期间野餐的好地方。

c)Could you tell us the reason(why/that)he was so unhappy ? 你能告诉我们他为什么如此不高兴吗？

3）当先行词为表示方式的 the way 时，从句不能用 how 来引导，应该用that 或 in which，或将它们全部省略。如：

I don't like the way(that/in which)you laugh at her.我不喜欢你嘲笑他的行为。

3．宾语从句中的省略

1）在及物动词后面所接的宾语从句中，连词that 一般可以省略；但如果及物动词后面是由that引导的两个或两个以上的并列的宾语从句，那么只有第一个that可以省略。如：

a)I think(that)the reform of the renminbi's exchange rate is necessary.我认为人民币兑换率的改革是必要的。

b)He said(that)the Anti-secession law had been passed and that President Hu Jintao had signed a presidential order 他说《 反分裂国家法》已被通过，而且胡锦涛主席已签署了主席令。2）由 which , when ,where , how,和 why 引导的 宾语从句，可以全部或部分省略。如：

a)I know that NBA star Yao Ming will come to our city but I don’t know when(he will come to our city).我知道NBA明星要到我们城市来但我不知道他什么时候来。

b)He wants to move abroad but his parents wonders why(he wants to move abroad)他想搬迁到国外但他的父母想知道为什么。

4．在与suggest ,request ,order ,advise 等词相关的名词性从句中，须用虚拟语气形式“should +动词原形”，should可以省略。如：

Chirac, President of the Republic of France suggested that the China-France Culture Year(should)last long in various forms.法国总统希拉克建议中法文化年以各种各样的形式长期持续。

5．主句省略多用于句首。如：

(It is a)Pity that I didn’t go to Mary's birthday party yesterday.很遗憾，我昨天没有去参加玛丽的生日聚会。

6．在答语中，主句可全部省略。如： —Why were you absent from school last Friday ?—(I was absent from school)Because my mother was ill.—上周五你为什么没有上学？ —因为我妈妈病了。

三、简单句中的省略

1．省略主语

1）祈使句中的主语通常被省略 如：

(You)Open the door, please.请开一下门。

2)其它省略主语多限于现成的说法 如：

a)(I)Thank you for your help 谢谢你的帮助。

b)(It)Doesn’t matter.没关系。

2．省略主谓语或主谓语的一部分 如：

a)(There is)No smoking.禁止抽烟

b)(Is there)anything else ? 还有其他事吗 ？

c)(You come)This way please.请这边走。

d)(Will you)Have a smoke ? 抽烟吗 ？

3．省略宾语 如：

—Do you know Mr.Li ? 你认识李先生吗？— I don’t know(him.)我不认识他 4．省略表语 如：

—Are you thirsty ? 你30岁了吗？ Yes , I am(thirsty).是的，我是。5．同时省略几个成分 如：

a)—Are you feeling better now? 你觉得好些了吗 ？—(I am feeling)Much better(now)好多了。

b)(I wish)Good luck(to you).祝你好运/祝你顺利。

四、动词不定式省略，只保留to 的场合1．不定式作某些动词的宾语时，这些动词常见的有：love, like, care, wish, hope, expect, prefer, refuse, mean , try , oblige , advise , persuade , agree , want , afford , forget , remember , try , manage等。如：

a)— You should have thanked her before you left.—I meant to ,but when I was leaving I couldn’t find her anywhere.—你本该在离开前谢谢她。—我本打算这么做，但当我就要离开的时候我却找不到她了。（2000上海春）

b)You can do it this way if you like to.如果你想做，你可以这么做。

2．不定式作某些动词的宾语补足语或主语补足语时，这些动词常见的有：ask , tell ,advise, force, persuade, wish, allow, permit , forbid ,expect, order ,warn 等。如 ：

a)The boy wanted to ride his bicycle in the street ,but his mother told him not to.男孩想在街上骑他的自行车，但他母亲不让。(NMET1995)

b)She wants to come but her parents won’t allow her to(come).她想来，可是她父母不让。

3．不定式在句中作某些形容词的状语时，常见的形容词有：happy, glad ,eager , anxious , willing , ready 等。如：

— I will be away on a business trip.Could you mind looking after my cat ?

— Not at all.I would be happy to(look after your cat).—我要出差，你能帮我照顾一下我的猫吗？—没关系，我很愿意。

4．不定式作某些复合谓语时，常见结构如：be able to, be going to, have to, ought to, used to等。如：

He doesn’t like fish but he used to 他现在不喜欢吃鱼，但过去喜欢。

五、动词不定式to 的省略

1．主语部分有to do ,系动词 is 或 was 时，作表语的不定式通常省去to。如：

The only thing you have to do is press the button.你必须做的惟一事情是按按钮。

2．作介词but ,expect ,besides 的宾语，前面又有实意动词 do时，不定式通常省去to.如：

He said that Chen Shuibian had nothing to do except push a pro-“independence” timetable.他说陈水扁除了推进支持“独立”的时间表外，什么也没有做。

3．主语部分暗含to do，表语中的不定式通常省去to。如：
