不定冠词的概念:

冠词是置于名词前,说明各词所表示的人或事物的一种虚词,它不能离开名词而单独存在。冠词有两种,一种是定冠词,一种是不定冠词。定冠词是the,不定冠词有两种形式,一是a,另一是an。不定冠词a用于辅音音素起首的单词前,an用于元音音素起首的单词前。如:a bike,  a dog,  an egg,  an elephant


不定冠词的特殊用法:

(1)用于序数词之前,表示数量或序数的增加:
如:Soon I saw a second plane.不久我又看到了另一架飞机。
        "This is the second time that I've read the book." “这是我第二次看这本书。”   
        "Do you want to read it a third time?"“你还想看第三次吗?”
(2)用于表示“非常”、“很”等意义的most前:
如:This is a most interesting story. 这是一个非常有趣的故事。
(3)用于物质名词前,使之转化为具体名词,表示“一种”、“一杯之量”等:
如:A coffee, please. 请给我来杯咖啡。 
        I'd like a tea, please. 我要来杯茶。
(4)用于抽象名词前,使之具体化,表示与该之相关的具体的人或事:
如:He was a success in business. 他事业成功。
        It's a pleasure to talk with you. 同你谈话是件令人愉快的事。
(5)用于指人的专有名词前,指某人、某人的作品或艺术品、…似(式)的人等:
如:A Mr Smith wants to see you. 一位名叫史密斯先生的人想见你。
        He bought a complete Lu Hsun. 他买了一套鲁迅全集。
        He thought he was a Zhu Geliang. 他自以为是诸葛亮。
(6)用于某些由动词转化来或具有动作意味的名词前,表示一次、一番等义(通常与have,take,make,give等动词连用):
如:Let's go out for a walk. 我们出去走走吧。
如:Do you care for as moke? 抽烟吗? 
        Would you like a drink? 要喝一杯吗?
(7)有的不可数名词或本来带有定冠词the的名词,由于受定语的修饰,其前可用不定冠词,表示某种状态。此时的不定冠词含有类似akindof的意思:
如:have breakfast 吃早餐─have a quick breakfast 吃快餐
        the world 世界─a world like ours 像我们这样的世界
(8)构成短语表示数量:
如:a few apples 几个苹果
        a little money 一点点钱
        a lot of time 许多时间
        a great many friends 许多朋友


不定冠词与one的用法解析:

1、两者均可表示“一”的意思,有时可互换。
如:About a[one] thousand students attended the meeting. 大约有1000学生参加了会议。
注:在数字开头时,两者均可用;但若不是数字开头,则应用one,如不可说three thousand a hundred,而说three thousand one hundred  
如:A [One]Mr Smith wants to see you. 一个名叫史密斯先生的人想见你。(a Mr...与one Mr...同义,也可说a certain Mr...,但如果没有Mr这样的词,两者则不宜随便互换,否则含意会发生变化。
2、尽管两者均可表示“一”,有时也可换用,但毕竟由于两者的词性不同,用法不同,在多数情况下是不能互换的:
(1)从词性上看:a(an)是不定冠词,主要表示类别,即着重表示其后的名词是某物,而不是其他物;而one表示“一(个)”时是数词,主要表示数量,即强调在数量上是一个,而不是两个或多个。
比较:Give me a dictionary. 给我一本字典。
            Give me one dictionary. 给我一本字典。
前者强调的是,我要的是一本字典,而不是一本教材,也不是一本小说等;而后者强调的是,我要的是一本字典,而不是两本字典或多本字典)。
再比较以下一组表达在意义上的区别:
more than a year一年多 (如一年零三个月等)
more than one year 不止一年 (如两年或三年等)
(2)由于one是数词,着重数量意义,所以当要强调数量、进行数量对比或回答how many的提问时,均应用one,而不能用a(an)。
如:He has only one pen, but I have two. 他只有一枝钢笔,但我有两枝。
        I want one box, not five. 我想要一个盒子,不是要五个。 
        —How many friends do you have here? 你在这儿有多少个朋友?
        —Only one.  只有一个。
(3)在某些表达中,两者均可用,但含义不同:at a time 每次,同时    at one time 一度,曾经 as a man 就一个人的性格而论  as one man一起,同时,全体一致地
在某些表达中,两者均可用,虽含义相同,但表达不同:
on a hot summe rafternoon 一个炎热的夏日的下午(注意用介词on)
one hot summer afternoon 一个炎热的夏日的下午(注意不用介词on) 
an hour and a half一个半小时(通常不说one hour and a half)
one and a half hours 一个半小时
a minute or two一两分钟(通常不说one minute or two)
one or two minutes 一两分种
在绝大多数习语中,两者是不能换用的。如:
in a hurry 匆忙     once up on a time 从前     as a result  结果      all of a sudden突然    oneday 一天  
one by one一个一个地     one and all 全部,每个人   one and the same 完全相同的


英语不定冠词(a/an)的用法:

1、用a还是an:一般说来,辅音或半元音[j, w]开头的词要前用a。
如:He has a computer (watch). 他有一台电脑(一块手表)。
        He's a university student (European). 他是大学生(欧洲人)。
元音开头的词前要用an。
如:This is an egg (hones tboy). 这是一只鸡蛋(诚实的男孩)。
注意:有的字母(如a,e,f,h,i等) 或缩略词,若第一个音是元音也应用an。
如:He missed an "n" in the word. 他写的这个单词漏了一个n。
2、不要从汉语习惯出发,漏掉必用的a/an。
如:他父亲是著名诗人。
误:His father is famous poet.
正:His father is a famous poet.
3、用于转化为普通名词的专有名词前,表示某某人或某某人的一部作品、艺术品等。
如:A Mr Smith wants to see you. 一位叫史密斯先生的人想见你。
        He bought a complete Lu Hsun. 他买了一套鲁迅全集。
4、用于转化为普通名词的物质名词前,表示相应的产品或种类,有时表示数量关系。
如:It’sagoodwine.这是(一种)好酒。 Twocoffeesandatea,please.请来两杯咖啡和一杯茶。
5、用于具体化的抽象名词前,表示与该抽象名词意义相关的人或事等。
如:The party was a great success. 晚会开得非常成功。
        It's a pleasure to talk with you. 同你谈话是件愉快的事。
6、用于某些由动词转化来或具有动作意味的名词前,表示一次、一番等意义。
如:Let me have a look. 让我看看吧。
        I'll give the car a good wash. 我要把车好好洗一洗。
7、用于序数词前表示数量或序数的增加。
如:He bought a second computer. 他又买了一台(即第二台)电脑。
        Later she borne a third son. 后来她又生了第三个儿子。
8、有的不可数名词或本来应该带定冠词(the)的名词,由于受定语(尤其是形容词)的修饰,其前一般要用不定冠词或改用不定冠词,表示某种状态,此时的不定冠词通常含有a kind of的意思。
如:have breakfast 吃早餐→have a quick breakfast 吃快餐
        the world 世界→a world like ours 像我们这样的世界
注:有些不可数名词即使受形容词的修饰也不能用不定冠词,容易弄错的有:news(消息),advice(忠告),luck(运气),fortune(运气),work(工作),fun(娱乐,有趣的事),weather(天气),homework(家庭作业),housework(家务活),information(情报),behavior(行为),harm(伤害),damage(损害),progress(进步),furniture(家具),baggage(行李),luggage(行李),poetry(诗),scenery(风景)等。
9、两个单数可数名词连用表示一个整体时,只用一个不定冠词。
如:He is a teacher and poet. 他既是老师又是诗人。
        There's a horse and cart on the road. 路上有一辆马车。
10、不定冠词可用来表示“类属”,这是其基本用法,它表明的是某一类属中的每一个人和东西都能说明该类属的整体情况(有类似汉语的“举一反三”或“以此类推”的含义)。此时也可用定冠词或名词复数形式来表示。
如:马是有用的动物。
正:A horse is a useful animal.
正:The horse is a useful animal.
正:Horses are useful animals.
若不是说明每一个人和东西的情况,而是说整个类属,则不能用不定冠词,而要用定冠词。
如:The tiger is indanger of becoming extinct.老虎面临绝种的危险。
        Alexander Graham Bell invented the telephone in 1876.亚历山大·格雷汉母·贝尔于1876年发明了电话。


不定冠词知识体系:

不定冠词 a 1、辅音音素开头的单词前用a,否则用an。
2、泛指,表“一个”但概念比one弱。
3、表类别 a+可数名词单数,不译为“一”。
4、表示单位,相当于“每”的意思。
5、用于序数词前,表“又一,再一”。
6、用于某些固定词组中,a lot of等。
an

使用不定冠词和不用不定冠词的差异:

1、英语中的某些名词即可用作不可数名词,又可用作可数名词,但是含义不同,用法也不一样。
如:iron 铁;an iron 一个熨斗
        kindness 和善; a kindness 一件善事
2、“with+抽象名词”使用时相当于副词,抽象名词前不用不定冠词。
如:with pleasure  乐意地
        with kindness  亲切地
        with joy  高兴地
        with diffculty 吃力地
        with angry    生气地
但在“with+a+名词”结构中虽有不定冠词,却没有实际意义。
如:with a smile 微笑地
        with an effort 努力地
        with a light heart  愉快地

因汉语习惯用错不定冠词的几种情形:
(1)单数可数名词若泛指,其前需加a/an,不要按汉语习惯漏掉此不定冠词:
如:他是著名影星。
正:Heisafamousfilmstar.
误:Heisfamousfilmstar.
(2)不定冠词不能与指示代词、物主代词、所有格等连用:
如:我在公园遇到了我的一位朋友。
正:Imetafriendofmineinthepark.
误:Imetmyafriendinthepark.
(3)不要受汉语影响而用错不定冠词位置:
如:我从未读过如此有趣的书。
正:Ihaveneverreadsuchaninterestingbook.
误:Ihaveneverreadasuchinterestingbook.
误:Ihaveneverreadasointerestingbook.

不定冠词的省略与重复

(1)在不引起误会的情况下,两个并列名词中的后一个名词前的不定冠词可以省略:
如:The noun is the name of a person or thing. 名词是人和物的名称。
(2)当两个并列名词指的是同一个人时,后一名词前的不定冠词通常省略:
如:His father is a teacher and poet. 他父亲是位教师兼诗人。
但如果要强调这两种身份,也可后一个不定冠词:
His father is a teacher and a poet. 他父亲既是教师,又是诗人。
有时,由于两个并列的名词关系比较紧密、被视为一个整体,也可只用一个冠词:
A man and woman are walking arm-in-arm.一对男女手挽着手走着。
(3)两个形容词并列同时修饰一个名词时,若该名词指的是两个事物,则通常应分别使用两个冠词:
如:We have a black and a white cat. 我们养了一只黑猫和一只白猫。
(比较:We have a black and white cat. 我们养了一只黑白花猫。)
但是,有时两个并列的名词只一个事物,为了加强语气,也有了两个冠词:
如:It was a cold and a dark night. 那是一个又冷又黑的夜晚。
(4)有些由两样东西构成的“自然成对”使用的事物,通常只在其前使用一个冠词:
如:a knife and fork一副刀叉 
        a cup and saucer 一副茶杯与茶托
        a horse and cart 一辆马车
        a needle and thread 一根带线的针
        hire a car and driver 租一辆配有司机的汽车
有时连第一个冠词也省略(尤其是与介词连用时):
如:with knife and fork 用刀叉
(5)当要对两个并列的名词进行选择和比较方面的强调时,通常应重复两个冠词:
如:Give me a pen, not a pencil. 给我一支钢笔,不是铅笔。
        Do you want a novel or a dictionary? 你是想要本小说,还是想要本字典?


物主代词的概念:

表示所有关系的代词叫物主代词。
物主代词有两种形式:一种是形容词性物主代词,在句中只能充当定语;另一种是名词性物主代词,和名词用法相同,在句中作主语、宾语、表语等。


 物主代词的特性:

1、物主代词既有表示所属的作用又有指代作用。
例如:John had cut his finger;约翰割破了手指。 
物主代词有形容词性(my,your等)和名词性(mine,yours等)两种,形容词性的物主代词属于限定词。  
名词性的物主代词在用法上相当于省略了中心名词的“'s”属格结构,
如:Jack's cap 意为 The cap is Jack's.   
        His cap  意为 The cap is his.   
2、名词性物主代词的句法功能:  
a.作主语,例如:May I use your pen? Yours works better.   
b.作宾语,例如:I love my motherland as much as you love yours.   
c.作介词宾语,例如:Your should interpret what I said in my sense of the word,not in yours.   
d.作主语补语,例如:The life I have is yours. It's yours. It's yours. 我的生命属于你,属于你,属于你。

形容词性物主代词的用法:

1、形容词性物主代词通常修饰名词,作定语。
如:We should treat her mother very well.
2、与own连用表示强调。
如:I saw it with my own eyes.

名词性物主代词的用法:

1、名词性物主代词可作主语、表语和宾语。
如:This is my desk. Yours is over there.
2、名词性物主代词常用于双重属格,于of连用。
如:This girl is a friend of mine.


物主代词知识体系

 


物主代词特别用法:

1、名词性和形容词性物主代词不能混用。
如:Jack has a low opinion of Sue.
2、物主代词的单复数必须和它所指代的名词一致。
如:His idea is to do more practice every day.
3、对于anyone,anybody,everyone,everybody,应根据上下文来判断his或her,有时也可用their。
如:Has everyone finished their work?


关系代词的概念:

英语中的关系代词有who, whom, whose, that, which, 它们是用来引导定语从句的。关系代词既代表定语从句所修饰的词,又在其所引导的从句中承担一个成分,如主语、宾语、表语、或定语。
如:This is the man who saved your son. (who在从句中作主语,先行词是man) 
        The man whom I met yesterday is Jim.
        A child whose parents are dead is an orphan.
        He wants a room whose window looks out over the sea.


关系代词用法:

1、that与which的用法区别:
      两者都可指物,常可互换。其区别主要在于:
(1)引导非限制性定语从句时,通常要用which:
如:She received an invitation from her boss, which came as a surprise. 她收到了老板的邀请,这是她意想不到的。
(2)直接放在介词后作宾语时,通常要用which:
如:The tool with which he is working is called a hammer. 他干活用的那个工具叫做锤子。
(3)当先行词是下列不定代词或被它们修饰时much, little, none, all, few, every(thing), any(thing), no(thing)等时,通常用that:
如:There was little that the enemy could do but surrender. 敌人无法,只有投降了。
        All[Everything] that can be done must be done. 凡能做的事都必须做。
(4)当先行词有the very, the only, the same等修饰时,通常用that:
如:This is the only example that I know. 我知道的例子只有这一个。
        Those are the very words that he used. 那是他的原话。
(5)当先行词有形容词最高级或序数词(包括last, next等)等修饰时,通常用that:
如:This is the best dictionary that I've ever used. 这是我用过的最好的词典。
        The first thing that you should do is to work out a plan. 你应该做的第一件事是订个计划。 
(6)当关系代词在定语从句中用作表语时,通常用that:
如:China is not the country(that) it was. 中国已不是过去的中国了。
(7)当先行词是一个既指人又指物的并列词组时,通常用that:
如:They talked about the persons and things that most impressed them. 他们谈论了使他们印象最深的人和事。
(8)当要避免重复时:
如:Which is the course that we are to take? 我们选哪门课程?

2、that与who的用法区别:

(1)两者均可指人,有时可互换:
如:All that[who] heard him were delighted. 所有听了他讲话的人都很高兴。    
        Have you met anybody that[who] has been to Paris? 你遇见过到过巴黎的人吗?
        He is the only one among us that[who] knows Russian. 他是我们中间唯一懂俄语的人。
(2)但是在下列情况,通常要用that: 
   ①当先行词是一个既指人又指物的并列词组时: 
如:I made a speech on the men and things that I had seen abroad. 我就我在国外所见到的人和事作了报告。
   ②当先行词是who时(为避免重复):
如:Who was it that won the World Cup in1982? 谁赢得了1982年的世界杯?
   ③当关系代词在定语从句中作表语时(可省略):
如:Tom is not the boy(that) he was. 汤姆这孩子已不是以前那个样子了。


关系代词知识体系:

 


关系代词用法拓展:

1、as与which的用法区别
(1)引导限制性定语从句时,在such,as,thesame后只能用as,其他情况用which:
如:I never heard such stories as he tells. 我从未听过他讲那样的故事。
        It's the same story as I heard yesterday. 这故事跟我昨天听到的一样。
        This is the photo which shows my house. 这张照片拍的是我的住宅。
(2)引导非限制性定语从句时,有时两者可互换:
如:I live a long way from work, as [which] you know. 我住得离工作单位很远,这你是知道的。
(3)但在,在以下情况引导非限制性定语从句时,两者不可换用:
①当从句位于主句前面时,只用as:
如:As is known to everybody, the moon travels round the earth once every month. 月球每月绕地球转一周,这是每个人都清楚的。
②as引导的非限制性定语从句应与主句在意义上和谐一致,which无此限制:
如:He went abroad, as[which] was expected. 他出国了,这是大家预料到的。
        He went abroad, which was unexpected. 他出国了,这让大家感到很意外。(不用as)
③as引导非限制性定语从句时,先行词通常不能是主句中某个具体的词,而应是整个句子、整个短语或某个短语推断出来的概念,而which则无此限制:
如:The river, which flows through London, is called the Thames. 这条流经伦敦的河叫泰晤士河。(不用as)
④当as引导非限制性定语从句作主语时,其谓语通常应是连系动词,而不宜是其他动词,而which则无此限制:
如:She has married again, as[which] seemed natural. 她又结婚了,这似乎很自常。
        She has married again, which delighted us.她又结婚了,这使我们很高兴。(不用as)

2、who与whom的用法区别:
两者均只用于人,从理论上说,who为主格,whom为宾格:
如:Where's the girl who sells the tickets? 卖票的女孩在哪里?
        The author whom you criticized in your view has written a letter in reply. 你在评论中批评的那个作者已写了一封回信。
但实际上,除非在正式文体中,宾格关系代词whom往往省略不用,或用who或that代之:
如:The man(that, who, whom) you met just now is called Jim. 你刚遇见的那个人叫吉姆。
不过,在以下几种情况值得注意:
(1)直接跟在介词后面作宾语时,只能用whom,而且不能省略:
如:She brought with her three friends, none of whom I had ever met before. 她带了3个朋友来,我以前都没见过。
(2)引导非限制性定语从句且作宾语时,who和whom均可用,但以用whom为佳,此时也不能省略:
如:This is Jack, who[whom] you haven't met before. 这是杰克,你以前没见过。


副词的比较级:

副词和形容词一样,也有它的比较级形式。表示两个人或事物之间的比较。用来修饰形容词、动词、其他副词或者整个句子。


副词的比较级的用法:

介词和介词短语的概念:

介词是一种用来表示词与词、词与句之间的关系的虚词,在句中不能单独作句子成分。介词后面一般有名词、代词或相当于名词的其他词类,短语或从句作它的宾语。介词和它的宾语构成介词词组,在句中作状语,表语,补语或介词宾语。介词可以分为时间介词、地点介词、方式介词和其他介词。


误用介词的三种情况:

1、多用介词:
多用介词可能是受汉语意思的影响将及物动词误用作不及物动词,也可能是受相关结构的影响而用错:
误:We discussed about the plan.
正:We discussed the plan. 我们讨论了计划。
误:Did he mention about the accident?
正:Did he mention the accident? 他提到那次事故了吗?
误:I saw her enter into the bank.

误:Who controls over the factory? (但名词control可接over)
正:Who controls the factory? 谁管理这个工厂?
误:He has a great many of friends here. (比较a great number of)
正:He has a great many friends here. 他在这儿有很多朋友。

2、漏用介词:
漏用介词可能是受汉语意思的影响将不及物动词误用作及物动词,或是受相关结构的影响的影响而用错等:
误:This matter is difficult to deal. (deal with=处理)
正:This matter is difficult to deal with. 这事很难处理。
误:He is not a man to be depended.
正:He is not a man to be depended on. 他不是个可靠的人。
误:He took a cup of tea, and went on the story.
正:He took a cup of tea, and wentonwiththestory.他喝了一口茶,又接着讲故事。
误:My mother still regards me a child. (比较consider…as中的as可省略)
正:My mother still regards me as a child. 我母亲还把我当小孩看。
误:They insisted sending a car over to fetch us.
正:They insisted on sending a car over to fetch us.他们坚持要派车来接我们。
误:What he says is worth listening.
正:What he said is worth listening to.他的话值得一听。

3、错用介词:
错用介词的情况比较复杂,可能是因受汉语意思的而错,也可能是因弄不清搭配关系而错,可能是混淆用法而错,也可能是受相关结构的影响而错,可能是忽略语境而错,也可能是想当然的用错:
误:She called on his office yesterday. (call on+人,call at+地点)
正:She called at his office yesterday. 她昨天去了他办公室拜访。
误:He is engaged with a nurse.
正:He is engaged to a nurse.他与一位护士订了婚。

误:We are familiar to his character.
正:We are familiar with his character.我们了解他的性格。
误:Help yourself with the fruit.
正:Help yourself to the fruit.吃点水果吧。


介词的宾语:

 1、名词或代词作介词宾语:
如:Are you interested in history? 你对历史感兴趣吗?
        Don't worry about it. 别为它担心。
注:若是人称代词用作介词宾语,要注意用宾格。
如:No one can sing like her. 没有人能像她那样唱歌。(不能用like she)

:过去分词用作介词宾语通常只见于某些固定结构中,如上面第1句涉及regard…as(认为…是)结构,第2句涉及take sth for granted(认为某事属实)。在其他情况下,介词后通常不直接跟过去分词作宾语,若语义上需要接过去分词(表被动),可换用“being+过去分词”:
如:He went out without being seen by the others.他出去了,没有被其他人看见。
4、从句作介词宾语:
如:He was not satisfied with what she said. 他对她说的不满意。
        I'm worried about where he is. 我担心他上哪儿去了。
:介词后通常不接that从句,遇此情况需考虑用其他结构:
误:He paid no attention to that she was poor.
正:He paid no attention to the fact that she was poor. 他根本不注意她很穷这一事实。
但有个别介词(如except)可接that从句。
比较:I know nothing about him except that he lives next door./I know nothing about him except for the fact that he lives next door. 我只知道他住在隔壁,其它的就不知道了。
5、不定式作介词宾语:
如:I had no choice but to wait. 除了等,我没有别的选择。

       They did nothing but complain. 他们老是一个劲地抱怨。 
       He never did anything but watch TV. 除了看电视,他从不干任何事。
:(1)介词后接不定式的情形通常只见于but, except等极个别个词。该不定式有时带to,有时不带to,其区别是:若其前出现了动词do,其后的不定式通常不带to;
若其前没有出现动词do,则其后的不定式通常带to。 
(2)介词后虽然通常不直接跟不定式作宾语,但却可接“连接代词(副词)+不定式”结构:
如:He gave me some advice on how to do it. 对于如何做这事他给我提了些建议。
6、形容词作介词宾语:
如:Her pronunciation is far from perfect. 她的语音远不是完美的。
        In short, we must be prepared. 总而言之,我们要有准备。
        Things have gone from bad to worse. 事情越来越糟。
:(1)有些形容词用作介词宾语可视为其前省略了动名词being:
如:He regarded the situationas(being) serious. 他认为形势严重。
        His work is far from(being) satisfactory. 他的工作丝毫不令人满意。 
(2)有些“介词+形容词”的结构已构成固定搭配:in full全部地,全面地,无省略地; in private私下地,秘密地; in particular特别地;in general一般地,通常地,概括地; in brief 简言之;in short总之,简言之; in vain徒然地,徒劳无益地;for fee免费地,无偿地; for certain肯定地,确切地;for sure肯定地,确切地; for short为了简短,简称;atl arge自由自在地,逍遥法外; by far…得多
7、副词作介词宾语:
如:I can't stay for long. 我不能久呆。 
        It's too hot in here. 这里面太热了。
        I looked every where except there. 除了那儿,我到处都看过了。
8、数词作介词宾语:
如:The city has a population of four million. 这座城市有四百万人口。
        He was among the first to arrive. 他是第一批到的。
9、介词短语作介词宾语:
如:Choose a book from among these. 从这些书中选一本吧。
        I saw her from across the street. 我从街的对面望见了她。
:通常可后接介词短语作宾语的介词是from, till, until, since, except, instead of等。
比较:I took it from the bed. 我从床那儿(或床上)拿的。
            I took it from under the bed. 我从床下拿的。 
10、复合结构用作介词宾语:

        She came in with a book in her hand. 她手里拿着一本书走了进来。
        All the afternoon he worked with the door locked. 整个下午他都锁着门在房里工作。

介词短语的句法功能:
1、表语:
如:He was with a friend. 他和一个朋友在一起。
        Health is above wealth. 健康胜过财富。
        This knife is for cutting bread. 这把小刀是用于切面包的。
:有些介词(如because of)引出的短语通常只用作状语,不用作表语:
误:His absence is because of the rain.
正:His absence is due to the rain. 他因雨未来。
但是,若主语是代词(不是名词),becauseof引出的短语可用作表语:
如:It is because of hard work. 那是因为辛苦工作的原因。
2、状语:
如:Don't touch it with your hands. 别用手去摸它。
        Did you do this by design or by accident? 你这样做是有意的还是无意的?
3、定语:
如:This is his reply to your letter. 这是他给你的回信。
        This is the best way of doing it. 这是做此事最好的方法。
        My love for you is deeper than the sea. 我对你的爱比海深。
4、宾语补足语:
如:I found everythingin good condition. 我发现一切正常。
       Her illness kept her in bed for a week. 她因生病在床上躺了一星期。
:用作宾语补足语的介词短语在相应的被动语态中则为主语补足语:
如:He was regarded as a hero. 他被看成是英雄。
5、宾语:
如:A man stepped out from behind the wall. 一个人从墙后走出来。
        He cannot spare anytime except on Sunday. 除星期日外,他抽不出时间。
6、主语:
如:Between6 and 7 suits me. 六点到七点对我比较适合。
        After the exams is the time to relax. 考试后是轻松一下的时间。
:介词短语通常不用作主语,尽管有时也像上面这样用作主语,但通常可视为是在一定的上下文中有所省略:
如:—When are we going to have the next meeting? 我们下次什么时候见面?
        —On Tuesday may be convenient. 星期二可能比较方便。
此句中onTuesday虽用作主语,但可视为是其前省略了meeting一词:
即:Meeting during the vacation may be convenient.

从属连词知识体系:

 


用作从属连词的六类名词结构:

英语中有些名词结构可用作从属连词,用以引导状语从句,且主要是时间状语从句。这类结构归纳起来有以下六类:
一、the+瞬间名词:
其中的瞬间名词主要包括moment, minute, instant, second等,其意为“一……就……”,相当于as soon as。
如:The minute he saw her he fell in love. 他对她一见倾心。  
Telephone me the moment(that) you get the results. 你一有结果,马上给我打电话。 
I was so tired that I fell asleep the instant I closed my eyes. 我很累,一合上眼就睡着了。
Sheputdownthereceiverthesecondsherecognizedmyvoice.她一听出是我的声音,马上就放下电话听筒。
注:其中的瞬间名词后可接that,也可省略。另外,有的个别副词(如directly/immediately等)也可表示类似意思。
如: Immediately the meal was over,he switchedon the radio.饭一吃完他就把收音机打开。

二、the+季节名词:
其中的季节名词包括spring,summer,autumn,winter,其意为“在……的那年春天、夏天、秋天、冬天。
如:His wife left him thes pring he went abroad.在他出国的那年春天,他的妻子离开了他。
He sold his house and went to the souththe summer he lost hisjob.在他失业的那年夏天,他卖掉房子去了南方。
He was sentto prison the winter his third daughter was born.在他第三个女儿出生的那年冬天,他被关进了监狱。
She got married the autumn she graduated from college.她大学毕业的那年秋天就结婚了。

三、the+时间名词:
其中的时间名词主要包括hour,day,night,week,month,season,year等,其意为“在……的时候、那天、那个晚上、那周、那个月、那个季节、那年”。
如: The hour he wa sin her office,he felt very sad.当他在她办公室的时候,他感到很伤心。
The day here turned home,his father was already dead.他回家的那一天,他的父亲已经死了。

They ear helivedinthecountry,he learned alot.他在乡下呆的那一年,他学到了不少东西。

四、the+序数词+time
其中的序数词包括first,second,third,fourth等,其意为“当第几次……的时候”。
如: My girlfriend beat me at pokert he first time weplayed.我头一次和女朋友打扑克,她就把我赢了。

The third time I went there,I found all of them had left and the offices were all empty.我第三次去那儿时,我发现他们都离开了,所有的办公室都是空的。
注:
1.next,last也具有类似序数词的性质,因此也具有以上用法。
如: Nexttimeyoucomein,pleaseclosethedoor.下次你进来,请关门。
Thelasttimewetalkedhesaidheneededanothertwodays.上次我们谈话时他说他还需要两天。
2.thefirsttime,thesecondtime,thethirdtime等用作连词引导时间状语从句时,其前通常要有定冠词,而(the)nexttime,(the)lasttime引导状语从句时,其中的冠词可以省略,如下面这道上海高考题,其答案是C,不是A:
I though ther nice and honest______Imether.
A.first time  B.fo rthe first time C.the first timeD.by the first time

五、不定代词+time
其中的不定代词主要包括each,every,any等。

He felt nervous each times he spoke to him.每次她和他讲话,他都感到紧张。
AnytimeyoucometoLondondolookmeup.你无论什么时候到伦敦来,一定要来看我。
注意:everytime,eachtime,anytime用作连词引导状语从句时其前习惯上不用冠词,它与the first time,these cond time,the third time等引导时间状语从句时其前必须要用定冠词不同。

六、其他名词结构
以上归纳的名词结构均用于引导时间状语从句,有些其他结构还可引导其他性质的状语从句,如the way可用于引导方式状语从句,表示“像……一样”。如:
The didn’t do it the way we do now.那时他们不像我们现在这样行事。
Joyce looked at me the way alotof girls did.乔伊丝像许多姑娘那样瞧着我。
注:这样用的theway与as用法相似。
如:Hold itin both hands,the way(=as)Mummy does.用两只手捧住,像妈妈那样。


动词的定义:

表示动作中状态的词叫做动词。根据其在句中的功能,动词可分为行为动词、系动词、助动词和情态动词四类,有些动词是兼类词。
例如:We have lunch at 12. (have是行为动词)
            We have been to NewYork. (have是助动词) 
            I am hungry. (am是系动词) 
            You need not have waited for me. (need是情态动词) 
            The door needs painting. (need是兼类词)


动词的分类:

1)表示动作中状态的词叫做动词。
2)根据其在句中的功能,动词可分为四类,分别是:
实义动词(Notional Verb)、系动词(Link Verb)、助动词(Auxiliary Verb)、情态动词(Modal Verb)。
说明:有些情况下,有些动词是兼类词。
例如:We are having a meeting. 我们正在开会。(having是实义动词。)
            He has gone to NewYork.他已去纽约。(has是助动词。)
3)动词根据其后是否带有宾语,可分为两类,分别是:
及物动词(Transitive Verb)、不及物动词(Intransitive Verb),缩写形式分别为vt.和vi.。
说明:同一动词有时可用作及物动词,有时可用作不及物动词。
例如:She can dance and sing. 她能唱歌又能跳舞。(sing在此用作不及物动词。)
            She can sing many English songs. 她能唱好多首英文歌曲。(sing用作及物动词。)
4)根据是否受主语的人称和数的限制,可分两类,分别是:
限定动词(Finite Verb)、非限定动词(Non-finite Verb)。
例如:She sings very well. 她唱得很好。(sing受主语she的限制,故用第三人称单数形式sings。)
            She wants to learn English well. 她想学好英语。(to learn不受主语she的限制,没有词形变化,是非限定动词。

动词知识体系:


肯定句的概念:

句子中不含否定词的就称为肯定句。肯定句的基本结构为:主语+谓语,陈述句的肯定形式分两种,一种为正常语序,一种为倒装语序。
例如:I have heard a lot that way. 
            In front of the car was Mike.
 


用于肯定句的常见结构:

1、already:
在通常情况下,already(已经)主要用于肯定句,一般不用于否定句或疑问句。
如:误:He hasn' tarrived already.
        正:He hasn't arrived yet. 他还没有到。
:有时用于否定句或疑问句中,主要表示惊讶。
如:Is he back already? 他怎么就回来了。
        Haven't you seen him already? 难道你还没见到好?
2、excellent:
excellent意为“极好的”,含有绝对无疑的意思,通常只用于肯定句,不用于否定句。
如:误:The film is not excellent.
        正:The film is not very good. 这部电影不是很好。
:excellent通常也不用于疑问句、条件句等。
3、hurry up:
hurry up主要用于肯定句(尤其是肯定的祈使句),一般不用于否定句。在否定句中,用hurry即可。
如:误:Don't hurry up; we have enough time.
        正:Don't hurry; we have enough time. 别急,我们有的是时间。
4、plenty(of):
在通常情况下,plenty(of)用于肯定句中,而不用于否定句中。
如:误:Have you plenty of food for the holidays?
        正:Have you enough food for the holidays? 你有足够的食物供假期里吃吗?
:在否定句或疑问中用enough, much, many等代之。具体地说,疑问句中通常用enough代替,否定句中通常用much,many代替。
比较:There is plenty of time. 时间还很多。 
            There isn't much time. 时间不多了。 
            Is there enough time? 时间还够吗?
5、some:
在通常情况下,some用于肯定句中,在否定句或疑问句中要用any代之。
如:误:I haven't some question to ask.
        正:I haven't any question to ask. 我没有问题要问。
:some有时也用于否定句,那多半有某种特殊的原因。
比较:I don't like any of the books. 这些书中我一本也不喜欢。
            I don't like some of the books. 这些书中有几本我不喜欢。
            I don't like some one of the books. 这些书中某一本我不喜欢。
另外,some有时也可用于疑问句,如希望得到肯定回答的疑问句,或表示请求或建议等。
如:May I have some paper? 我可以拿些纸吗?
        Why not give her some flowers? 为什么不给她送些花呢?
表示“也”的副词also, too, as well通常不用于否定句,而主要用于肯定句或疑问句。
如:误:I don't like the film too. 
        误:I don't also like the film as well.
        误:I don't like the film as well.
        正:I don't like the film either. 我也不喜欢这部电影。
:also和too有时可用于肯定句后所接的否定句中,表示“没有也……”。
如: Heleftbutshedidn’talsoleave.他走了,但她没有也一起走。
          He bought a computer, but she didn't too. 他买了台电脑,但她没有也买台电脑。
另外,在正式文体中,also, too有时可用于否定词之前。
如:I also don't like it. 我也不喜欢它。
        I, too, have never met anyone like him.我也是,没见过和他一样的人。


主语从句的概念:

如果一个句子在复合句中充当一个主语,那么这个句子就是主语从句。主语从句通常由从属连词that,whether,if和连接代词what,who,whichwhatever,whoever以及连接副词how,when,where,why等词引导。that在句中无词义,只起连接作用。


主语从句用法:

1、主语从句的引导词:
主语从句通常由连词that和whether、连接代词或连接副词以及关系代词型what引导:
如:That he is still alive is a wonder. 他还活着,真是奇迹。
        When we arrive doesn't matter. 什么时候到没有关系。
        What we need is money. 我们需要的是钱。
        What I want to know is this. 我想知道的就是这一点。
        Whether they would support us was a problem. 他们是否会支持我们还是一个问题。

2、主语从句与形式主语it:
有时为了考虑句子平衡,通常在主语从句处使用形式主语it,而将真正的主语从句移至句末。这分三种情况:
(1)对于以连词that引导的主语从句,通常用形式主语代主语从句:
如:It's a pity that he didn't come. 很遗憾他没来。
(2)对于以连接代词(副词)引导的主语从句,可以使用形式主语代主语从句,也可直接在句首使用主语从句:
如:Whether they would support us was a problem. 他们是否会支持我们还是一个问题。  
        It was a problem whether they would support us. 他们是否会支持我们还是一个问题。
(3)对关系代词型what引导的主语从句,通常不用形式主语,总是主语从句放在句首:
如:What we need is money. 我们需要的是钱。
        What I want to know is this. 我想知道的就是这一点。
(4)如果句子是疑问句,则必须用带形式主语it的结构:
如:Is it true that he is the girl's father? 他是那女孩的父亲,是真的吗?
        How is it that you are late again? 你怎么又迟到了?

3、连词that的省略问题:
引导主语从句的连词that有时可省,有时不能省,其原则是:
若that引导的主语从句直接位于句首,则that不能省略;
若that引导的主语从句位于句末,而在句首使用了形式主语it,则that则可以省略:
如:That you didn't go to the talk was a pity. 很遗憾你没去听报告。(that不可省)
        It was a pity(that) you didn't go to the talk. 很遗憾你没去听报告。(that可省)


主语从句应注意的几个问题:

1、that引导的主语从句既可放在句首,也可放在句尾,但在下列情况下that从句不可提前。
(1)在It is said/reported...that结构中:
如:It is reported that a bank was robbed yesterday.
(2)在Ithappened/occurred...结构中:
Ithappenedthattheteacherwasnotintheofficethatday.
(3)含主语从句的复合句是疑问句时:
如:Is it ture that you will give up the job?
2、下面这种情况常用it作形式主语。在It doesn't matter+what/whatever…结构中。
如:It doesn't matter what you say.
3、由what引导的主语从句谓语动词单复数问题 what引导的主语从句一般按单数对待,但是,在实际使用中究竟按单数还是按复数对取决于其成分的含义。
如:What we need is more time.
        What were left behind were five empty bottles.
