高中英语语法知识点1
冠词
高考对冠词的考查集中在基本用法上，主要既反映在对泛指、特指及固定 短语 冠词的考查。抽象名词、物质名词的具体化依然是高考的重点、难点。
一、不定冠词
不定冠词a，an与one同源，表示微弱的一的概念，但并不强调数目，用来表示不确定的人或事物。
A用在辅音前，而不是辅音字母前;an用在元音前，而不是元音字母前。
a university in Asia
1.表示同类中的任何一个
A cat has nine lives.
2.表示泛指的某人、某物
I know a John Lennon，but not the famous one.
3.表示数量的一 He has a daughter.
4. 表示单位数量的每一 I earn 10 dollars an hour.
5.表示相同的

7. 在某种情况下可用于抽象名词和物质名词前 China has a long history.
二、定冠词的用法
1.表示特定的人或物
2.表示地球、宇宙中独一无二的事物
主要指各种天体及世界上比较有影响的物体。 The sun，the moon，the earth

7)用于by+the+计量单位名词 By the pound
1. 用于复数名词前
复数名词泛指某类人或物时，其前通常用零冠词。 Students should obey the school rules. 学生应该遵守校规。 复数名词若需特指，则要加定冠词。 The students are too lazy. 这些学生太懒。
2. 用于不可数名词前
不可数名词表示泛指时，其前通常用零冠词。如： Bread is made from flour. 面包是用面粉做的。
Wood is a poor conductor of sound. 木头是声音的不良导体。 不可数名词若需特指，则要加定冠词。
He sawed the wood into three pieces. 他把木头锯成三块。
3.用于专有名词前
在通常情况下，专有名词前要用零冠词。如：
Mr Smith is our English teaches us English. 史密斯先生教我们英语。 在特殊情况下，若专有名词需要特指，也可加定冠词。如： The Smith you‘re looking for no longer lives here.
4. 用于抽象化的可数名词前
有些可数名词抽象化后表示表示的活动，其前通常零冠词。 Jim has gone to bed. 吉姆已上床睡觉了。
She goes to church every Sunday. 她每周星期天都去做礼拜。
这类主要涉及bed, church, class, college, school, university, work, hospital, prison, market, sea, town等。另外，这类名词前用不用冠词有时与英美英语的表达习惯有关。如：―住院‖在英国英语中通常说成 in hospital，而在美国英语中则通常说成in the hospital;类似的还有go to university (英)上大学 / go to the university (美)上大学;at table (英)在吃饭 / at the table (美)在吃饭。

Happy Christmas?
英语可说happy Christmas 吗?请看这样一道题：
—__________ Christmas!
—Same __________ you.
A. Merry, as B. Merry, on C. Happy, as D. Happy, to
此题应选 D。容易误选A，B。错误思维是：
1. 可以说 Happy new year, 但必须说 Merry Christmas.
2. the same as, the same...as 是固定搭配。
关于第2点，比较好解释，因为(The) Same to you. 是口语惯用语，回答祝愿，其意为“也祝你……”。
而第1点搞错的人就很多了，不少人都想当然地认为不能像Happy New Year, Happy birthday那样用Happy Christmas, 其实这是一种典型的想当然错误，请看有关_词书的实例。如：
1. 大家熟悉的《朗文当代英语词典》(1987年版)就多处出现 Happy Christmas 的用例。如：
1)Happy Christmas. (p. 476，happy词条)
2)"Happy Christmas. " "Same to you. " (p. 925 same 词条)
2. 又如章振邦教授主编的两本英语语法著作。如：
1)Happy Christmas. 《新编英语语法教程》(p. 459)
2)A Happy Christmas to all. 《新编英语语法》(上册p. 183)
3. 再如《 英语学习 》杂志，1992年第7期p. 17的一段对话中，多次将 Happy Christmas 与 Merry Christmas 交替使用。
4. 如果你是一个层次稍高的英语学习者，你可能会读过杨岂深教授主编的《英国文学选读》(Book 3)，如果你细心的话，你会发现该书 ANGLO-SAXON ATTITUDES 一文里，也在多次交替使用 Happy Christmas 和 Merry Christmas。
一、非谓语动词
“非谓语动词”可分为动词不定式、动名词和分词.它在句子中的作用很多：除了不作谓语外,它可以充当主语、宾语、表语、定语、状语与复合宾语(主语补语或宾语补语).有些及物动词后面接不带to的不定式作复合宾语.这些动词归纳如下：一感(feel).二听(hear,listen to),三让(have,1et, make),四看(see,watCh,notice,observe).再加上help somebody(to)do something和美国英语look at somebody do somthing.还有“二让”属特殊：get somebody to do something 与keep somebody doing.而有些及物动词后面接动名词(the -ing form)作宾语.这些动词归纳为一句话：Papa C makes friends.这是由如下动词的开头字母组成：permit,advise, practise,avoid,consider,mind, allow,keep,enjoy,suggest, finish,risk,imagine,escape,need,delay,stand(忍受). 为了容易记住,也可以编成 顺口溜 ：“允许完成练习,建议避免冒险,考虑延期逃跑,喜欢保持想象,需要反对忍受”.其相对应的动词依次是：permit/allow,finish,practise;
advise/suggest, avoid,risk： consider, delay, escape/miss; enjoy/appreciate, keep, imagine; need/want/require,mind. can't help/can’t stand.
二、复合句
1、学生最容易混淆的是定语从句与同位语从句的区别.
例如：A、The news that our team has won the match is true. (同位语从句)
B、The news that he told us surprised everybody here. (定语从句)
关键的区别在于连接或关系代词that：有意义的是定语, 无意义的是同位.因为引导定语从句的that在从句中作主语或 宾语,而引导同位语从句的that只起到连接词的作用.
2、接着容易混淆的是引导定语从句的关系代词that与 which：that之前是不定(代词)、序数(词)、(形容词)级：which之前是介词短语与逗号(非限制性).
例如：A、All that we have to do is to practise every day.
B、The first lesson that I learned will never be forgotten.
C、I have lost my pen,which I like very much.
D、The house in front of which there is a garden is my home.
三、It的用法
1、It除了代替人和物以外,还可以作形式主语.而真正的主语(不定式、动名词或从句)则放于谓语或表语之后.
例如：It is nor easy to finish the work in two days.
然而有少数表语之后接动名词作真正的主语.这些表语是：无助(no help)、无用(no use)、没好处(no good);工作(hard work)、费时(a waste of time)、又危险(a danger).
例如：A、It is no use crying over spilt milk.
B、It is a waste of time waiting for him.
2、It还可以作形式宾语.通常下列动词后面可接it作形式宾语：2f2tcjm(find,feel,think,take,consider,judge, make).
例如：A、He made it clear that he was not interested in this subject.
B、I think it no use arguing with him.
3、It用于强调句式.要强调句子的某一部分(主语、宾语、 状语),可以把it当作先行词.这种句子的结构是：It is(was)+ 被强调部分+that(who)+句子的其余部分.
例如：A、It iS Professor Lin who teaches us English—(强调主语)
B、It was in Shanghai that l saw the film.—(强调状语)
C、It was in 1990 that I worked in the factory.(同上)
但要注意与定语从句的区别.
例如：D、It was 1990 when I worked in the factory.(定语从句)
在强调句式里,我们把强调结构It is(was)…that除去,句子还很完整.如例句C.而例句D就不能.
四、倒装结构
学生容易混淆的是全部倒装与部分倒装.如何区分之,编个顺口溜：副(adv.)介(prep.)提前全倒装, 其它 句式部分倒;否定提前倒助动,让步状语倒表语;复合句式倒主句,不
倒装的属特殊.下面举例说明：
A、Here comes the bus.(副词提前,全倒装)
B、Here he comes.(代词作主语,不倒装)
C、In front of the house lies a garden.(介词短语提前,全倒装)

五、虚拟语气
虚拟语气也是一个难点.所谓虚拟语气是表示说话人的愿望、假设、猜测或建议,而不表示客观存在的事实.它通过句子的谓语动词的特殊形式来表示.现归纳如下：纯假设,用虚拟,动词时态退一级：条件句,分主从,主句谓语前加would (should,could,might);表愿望,用虚拟,wish后面接宾语(从句)：现在过去与将来,动词时态退一级：提建议,用虚拟,宾语(从句)动词用(should)do：俩建议,三要求,再加坚持与命令(suggest,advise,demand,require,request,insist,order)：It is time和eoukd rather,后接丛句用虚拟：部分主语从句中, 谓语用虚拟结构 (It is necessry /important/natural/natural/strange/strange that……should do). 下面举例说明：
A、If you came tomorrow,we would have the metting. (条件句虚拟)
B、Without air,there would be no living things.(同上)
C、We wish we had arrived there two hours earlier.(表示愿望虚拟)
D、He demanded that we (should)start right away.(表示建议虚拟)
E、It is(high)time that we left (should leave)now.(特殊从句虚拟)
F、I would rather you gave me the book.(同上)
G、It is necessary that we should clean the room everyday,(主语从句虚拟)
H、He speaks English so fluently as if he were English. (特殊从句虚拟)
