名词的格的种类:
在句中表示所有关系的语法形式称为名词所有格。
例如:Tom's best friend is Mary. (Tom's 是所有格,Mary为通格)
The title of the book is interesting. (of the book为所有格)
-'s所有格的用法:
-'s所有格主要用于有生命的东西,但有时也可用于无生命的东西,这主要见于:
(1)用于表时间的名词后:
tomorrow's weather 明天的天气
two days' journey两天的旅程比较:
ten minutes' break=a ten-minute break 10分钟的休息
(2)用于表国家、城市的名词后:America's policy 美国的政策 the city's population 这个城市的人口
(3)用于某些集合名词后:the majority's view 多数人的观点 the government's policy 政府的政策
(4)用于组织机构后:the station's waiting-room 车站候车室 the newspaper's editorial policy 这家报纸的编辑方针
(5)用于度量衡及价值名词后:a mile's distance1 英里的距离 twenty dollar's value 20美元的价值
注:对于带有连字符已转化为形容词的度量衡,不能用所有格形式:ten-minute walk 10分钟的路程 (比较:ten minutes' walk)
(6)用于表天体的名词后:the moon's rays 月光 the earth's surface 地球表面
(7)用于某些固定表达中:a stone's throw 一箭之遥 at one's wit's end 黔驴技穷 at arm's length 以一臂之距 out of harm's way 在完全的地方
注:名词所有格并不一定表示所有关系,有时可能表示其他意义:
(1)表类别:a doctor's degree 博士学位,Children's hospital 儿童医院
(2)表动作执行者:Mr Smith's arrival 史密斯先生的到达
(3)表动作承受者:Children's education 儿童教育
-'s所有格与of所有格的用法比较:
(1)of 所有格既可用于有生命的人或物,也可用于无生命的东西。of 所有格有时可以与-'s所有格互换。如:
Mr Smith's son=the son of Mr Smith 史密斯先生的儿子
Jim's patience=the patience of Jim 吉姆的耐心
the Queen's arrival=the arrival of the Queen 女王的到达
(2)必须用's所有格的情形:
①表类别时:men's shoes男鞋,Children's stories儿童故事
②表来源时:John's telegram 约翰的电报
③当被修饰的名词后有同位语修饰时:
Mary's husband, a policeman, has just been here. 玛丽的丈夫是个警察,刚刚来过这儿。
(3)必须用of 所有格的情形:
①用于无生命的事物时:the subject of the sentence 句子主语
②表同位关系时:the City of Beijing 北京市
③当中心词是名词化的名词时:the life of the poor 穷人的生活
④当of 所有格中的名词后跟有后置修饰语或同位语时:
Mr Smith is a foreign teacher of a university in China.史密斯先生是中国一所大学的外籍教师。
-'s所有格的构成方法:
(1)一般情况(包括单数名词和不带词尾s的复数名词)加-'s:Children's books儿童图书 today's paper今天的报纸
(2)带词尾s的复数名词只加省字撇( ' ):girls' school女子学校 the Smiths'car 史密斯家的小汽车
注:带词尾s的单数名词,通常仍加's:the boss's plan 老板的计划 the hostess's worry女主人的担心
(3)带词尾s的人名,可加's或只加省字撇( ' ):Dickens' novels 狄更斯的小说 Charles's job查理斯的工作。
不带词尾-s却以咝音结尾者,一律加's:Marx's works 马克思的著作 George's room 乔治的房间
(4)用and连接的并列连词的所有格要分两种情况,即表示各自的所有关系时,要分别在并列连词后加-'s,表示共同的所有关系时,只在最后一个名词后加-'s:
Tom's and Jim's rooms 汤姆和吉姆(各自)的房间
Tom and Jim's rooms 汤姆和吉姆(共同)的房间
名词所有格知识体系:
双重所有格的使用:
(1)所谓双重所有格就是指将“-'s”所有格与of 所有格结合起来一起使用: a friend of my father's 我父亲的一位朋友 a photo of Mr Smith's 史密斯先生的一张照片
(2)双重所有格的使用场合:
①当被修饰名词前有指示代词、疑问代词、不定代词或数词等限定词时,一般要用双重所有格:
如:I don't like that big nose of David's. 我不喜欢大卫的那个大鼻子。
Which novel of Dickens' are your eferring to? 你谈的是狄更斯的哪部小说?
Some friends of my brother's wil lcome. 我兄弟的一些朋友要来。
注:被双重所有格修饰名词前有指示代词时,通常带有一定的感情色彩(如赞赏或厌恶等)。
如:That little daughter of your cousin's is really a dear. 你表哥的那个小女儿真是逗人爱。(表赞赏)
That daughter of your cousin's is constantly complaining.你表哥的那个女儿老是在报怨。(表厌恶)
另外,被双重所有格修饰的名词前可以用不定冠词,但通常不用定冠词:
可以说:a poem of Shelly's, a novel o fDickens'
不能说:the poem of Shelly's, the novel of Dickens'
②有时既可用双重所有格也可用of 所有格,但含义稍有差别。
比较:a photo of Mary's 玛丽收藏的一张照片
a photo of Mary 玛丽照的一张照片
a criticism of William's 威谦提出的批评
a criticism of William 对威谦的批评
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?
并列连词的概念:
连词是一种虚词,它不能独立担任句子成分而只起连接词与词,短语与短语以及句与句的作用。连词主要可分为两类:并列连词和从属连词。并列连词用来连接平行的词、词组和分句。如:and, but, or, nor, so, therefore, yet, however, for, hence, as well as, both...and, notonly...butalso, either...or, neither...nor, (and)then 等等。
并列连词与并列结构:
并列连词引导两个并列的句子。
1)and与or:
判断改错:
(错) They sat down and talk about something.
(错) They started to dance and sang.
(错) I saw two men sitting behind and whisper there.
(对) They sat down and talked about something.
(对) They started to dance and sing.
(对) I saw two men sitting behind and whispering there.
解析:第一句:and连接两个并列的谓语,所以talk应改为talked。
第二句:and连接两个并列的动词不定式,第二个不定式往往省略to,因此sang应改为sing。
第三句:and连接感观动词saw后面的用作的宾补的两个并列分词结构,因此whisper应改为whispering。
注意:and还可以和祈使句或名词词组连用表示条件。(or也有此用法)
如:Make up your mind, and you'll get the chance.=If you make up your mind, you'll get the chance.
One more effort, and you'll succeed.=If you make one more effort, you'll succeed.
2)both...and 两者都
如:She plays(both) the piano and the guitar.
3)not only...but(also), as well as 不但…而且
如:She plays not only the piano, but(also) the guitar.
注意:not only…but also关联两个分句时,一个分句因有否定词not而必须倒装。
如:Not only does he like reading stories, but also he can even write some.
4)neither...nor 意思为“既不……也不……”谓语动词采用就近原则,与nor后的词保持一致。
如:Neither you nor he is to blame.
比较so和such :
so与such的用法由不同词性决定。such是形容词,修饰名词或名词词组,so是副词,只能修饰形容词或副词。so还可与表示数量的形容词many,few,much,little连用,形成固定搭配。
构成:so+adj.
such+a(n)+n.
so+adj.+a(n)+n.
such+n.(pl.)
so+adj.+n.(pl.)
such+n.(pl.)
so+adj.+n.[不可数]
such+n.[不可数]
如:so foolish
such a fool
so nice a flower
such a nice flower
so many/few flowers
such nice flowers
so much/ little money.
such rapid progress
so many people
such a lot of people
注:so many 已成固定搭配,a lot of 虽相当于many,但a lot of为名词性的,只能用such搭配。 so...that与such...that之间的转换既为so与such之间的转换。
并列连词用法点拨:
1、表示并列关系:
1)or意思为“否则”。
如:I must work hard, or I'll fail in the exam.
2)either...or意思为“或者……或者……”。注意谓语动词采用就近原则。
如:Either you or I am right.
2、表示转折或对比关系:
1)but表示转折,while表示对比。
如:Some people love cats, while others hate them.
典型例题:
—Would you like to come to dinner tonight?
—I'd like to, ___ I'm too busy.
A. and
B. so
C. as
D. but
答案:D。but与前面形成转折,符合语意。而表并列的and,结果的so,原因的as都不符合句意。
2)not...but...意思为“不是……而是……” not和but后面的用词要遵循一致原则。
如:They were not the bones of an animal, but(the bones) of a human being.
3、表示原因关系:
1)for 判断改错:
(错)For he is ill, he is absent today.
(对)He is absent today, for he is ill. for是并列连词,不能置于含两个并列分句的句子的句首,只能将其放在两个分句中间。
并列连词知识体系:
种类 | 用法 | 举例 |
并列连词 | 表示转折关系 | yet, but等 |
表示并列关系 | and, or, either...or..., as welll as等 | |
表示因果关系 | for, so等 |
比较and和or的用法:
1)并列结构中,or通常用于否定句,and用于肯定句。
2)但有时and也可用于否定句。请注意其不同特点:
如:There is no air or water in the moon.
There is no air and no water on the moon.
在否定中并列结构用or连接,但含有两个否定词的句子实际被看作是肯定结构,因此要用and。
典型例题:
—I don't like chicken___fish.
—I don't like chicken, ___I like fish very much.
A. and;and
B. and;but
C. or;but
D. or;and
答案:C。否定句中表并列用or,but表转折。
判断改错:
(错)We will die without air and water.
(错)We can't live without air or water.
(对)We will die without air or water.
(对)We can't live without air and water.
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。
说明:英语中共有三种非限定动词,分别是:动词不定式(Infinitive)、动名词(Gerund)、分词(Participle)。
5)根据动词的组成形式,可分为三类,分别是:
单字词(One-Word Verb)、短语动词(Phrasal Verb)、动词短语(Verbal Phrase)
例如:The English language contains many phrasal verbs and verbal phrases. 英语里有许多短语动词和动词短语。(contains是单字动词。)
Students should learn to look up new words in dictionaries. 学生们学会查字典。(look up是短语动词。)
The young ought to take care of the old. 年轻人应照料老人。(takecareof是动词短语。)
6)动词有五种形态,分别是:
原形(OriginalForm)、第三人称单数形式(Singular From in Third Personal)、过去式(Past Form)、过去分词(Past Participle)、现在分词(Present Participle)。
动词知识体系:
动名词概念:
动名词是一种兼有动词和名词特征的非限定动词。它可以支配宾语,也能被副词修饰,动名词有时态和语态的变化。
现在分词和动名词用法比较:
动词的-ing形式包括现在分词和动名词两种形式。他们的句法功能如下:
动词的-ing形式如果作句子的主语或者宾语时,应该是动名词形式;如果作补语或者状语时,应该是现在分词形式。那么作表语或者定语的动名词和现在分词又该怎样区分呢?
1、动名词与现在分词作表语时的比较:
(1)动名词作表语说明主语的内容,回答what的问题;现在分词作表语相当于形容词作表语,说明主语的性质、特征等,回答how的问题。
如:One of the best exercises is swimming. 游泳是最好的运动项目之一。
What pleases him most is bathing in the sea. 最使他高兴的事是在海中沐浴。
The situation both at home and abroad is very in-spiring. 国内外的形势都很鼓舞人心。
The color is pleasing to the eye. 颜色悦目。
(2)动名词作表语,表语和主语几乎处于同等地位,可以互换位置,其句意不变;现在分词作表语,表语和主语则不能互换位置。
如:Our work is serving the people.
(=Serving the people is our work.)我们的工作是为人民服务。
The news was disappointing. 那消息令人失望。
(3)作表语的现在分词前可以用very,quite,rather,greatly等副词修饰,而动名词则不可以。
如:What he said was very encouraging. 他的话很鼓舞人心。
Our goal is realizing the four modernizations in the near future. 我们的目标是在不久的将来实现四个现代化。
(4)现在分词与形容词一样可以和more,the most构成形容词的比较级和最高级,而动名词则不可以。
如:The story is the most fascinating. 那个故事最迷人。
(5)作表语用的现在分词除了和be连用以外,还可以和其它的系动词连用;而作表语的动名词则通常只能和be连用。
如:His speech seems inspiring.他的演讲似乎很鼓舞人心。
His interest is writing for the news papers. 他的爱好是给报社写文章。
(6)有些用作表语的现在分词已经形容词化了。常见的有:exciting,moving,inspiring,missing,interesting,disappointing等。
2、动名词与现在分词作定语时的比较:
(1)动名词作定语时,表示它所修饰的名词的性能和用途,和它所修饰的名词在逻辑上没有主谓关系;
现在分词作定语时,表示它所修饰的名词正在进行的动作,和它所修饰的名词在逻辑上有主谓关系,常可以扩展成一个定语从句。
如:a swimming girl=a girl who is swimming 一个在游泳的姑娘
a walking stick=a stick that is used for walking 一根拐杖
(2)现在分词作定语有时可以后置,而动名词则通常只能放在它所修饰的名词之前。
如:The girl wearing glasses is one of his students. 戴眼镜的那个女孩是他的一个学生。
I bought some reading materials. 我买了一些阅读材料。
动名词的用法:
1、作主语:
例如:Fighting broke out between the South and the North. 南方与北方开战了。
2、作宾语:
a. 有些动词可以用动名词作宾语。
例如:admit承认 appreciate感激 avoid避免 complete完成 consider认为 delay耽误 deny否认 detest讨厌 endure忍受 enjoy喜欢 escape逃脱 fancy想象 finish完成 imagine想象 mind介意 miss想念 postpone推迟 practice训练 recall回忆 resent讨厌 resume继续 resist抵抗 risk冒险 suggest建议 face面对 include包括 stand忍受 understand理解 forgive宽恕 keep继续
例如:Would you mind turning down your radio a little, please? 你把收音机音量调小一点,好吗?
The squirrel was lucky that it just missed being caught. 这松鼠幸运得很,刚逃避了被逮住的厄运。
b. 有些结构后面可以用动名词作宾语或其他成分。
例如:admit to prefer...to burst out keep on insist on count on set about put off be good at take up give up be successful in be used to lead to devote oneself to object to stick to no good no use be fond of look forward to be proud of be busy can't help be tired of be capable of be afraid of think of
3、作表语,对主语说明、解释:
例如:Her job is washing, cleaning and taking care of the children. 她的工作是洗刷、清扫和照顾孩子。
比较:She is washing, cleaning and taking care of the children.
4、作定语,一般表示所修饰名词事物的用途:
例如:a writing desk=a desk for writing 写字台
a swimming pool=a pool swimming 游泳池
有些动名词作定语,与所修饰的名词关系比较复杂。
例如:boiling point=a temperature point at which something begins to boil 沸点
a walking tractor=a tractor which a driver can operate while he or she is walking behind it 手扶拖拉机
动名词知识体系:
动名词与不定式用法对比:
一般现在时的被动语态的概念:
表示的是一般现在时态和被动语态的叠合。构成:(am/is/are +done)
如:This shirt is washed once a week. 这件T恤一周洗一次。
主动语态变被动语态的方法:
1、把主动语态的宾语变为被动语态的主语。
2、把谓语变成被动结构(be+过去分词),根据被动语态句子里的主语的人称和数,以及原来主动语态句子中动词的时态来决定be的形式。
3、把主动语态中的主语放在介词by之后作宾语,将主格改为宾格。
例如:All the people laughed at him.=He was laughed at by all people.
They make the bikes in the factory.=The bikes are made by them in the factory.
记忆歌诀:
宾变主,主变宾,by短语后面跟。
谓语动词变被动,be后“过分”来使用。
含有情态动词的被动语态:
含有情态动词的主动句变成被动句时,由“情态动词+be+过去分词”构成,原来带to的情态动词变成被动语态后“to”仍要保留。
记忆歌诀:
情态动词变动,情态加be加“过分”,原来带to要保留。
例如:We can repair this watch in two days.=This watch can be repaired in two days.
You ought to take it away.=It ought to be taken away.
They should do it at once.=It should be done at once.
被动语态的用法:
1、不知道或没有必要说明动作的执行者是谁。
例如:Some new computers were stolen last night.一些新电脑在昨晚被盗了。(不知道电脑是谁偷的)
This book was published in1981.这 本书出版于1981年。
2、强调动作的承受者,而不强调动作的执行者。
例如:This book was written by him. 这本书是他写的。
Eight hours per day for sleep must be guaranteed. 每天8小时睡眠必须得到保证。
记忆歌诀:
谁做的动作不知道,说出谁做的没有必要;动作承受者需强调,被动语态运用到。
一般现在时的被动语态:
一、被动语态的结构:
主语(动作接受者)+is/am/are+动词的过去分词+(by+动作执行者)
如:Football is played in most countries in the world.
被动语态的句型总结如下:
1、肯定句:主语+be+过去分词+(by~~).
如:The boy is called Jack.
2、否定句:主语+be not+过去分词+(by~~).
如:The baby is not looked after by his father.
3、一般疑问句:Be+主语+过去分词+(by~~)?
如:Is KingLear written by Shakespeare?
4、特殊疑问句:特殊疑词+be+过去分词+(by~~)?
如:What is this kind of sweater made of?
二、被动语态的用法:
1、要表达“被…”、“受…”、“让…”、“遭…”之类的语义。
如:The teachers are well respected.
The child is well loved by people.
2、强调动作承受者。
如:He is known far and wide. 他远近闻名。
3、不知道式没有必要指出动作的执行者。
如: The room is cleaned every day. 房子每天都有人打扫。
4、为礼貌起见避免提及动作执行者。
如:I wonder if I was allowed to introduce myself? 我是否可以做自我介绍?
状语从句的概念:
状语从句指句子用作状语时,起副词作用的句子。它可以修饰谓语、非谓语动词、定语、状语或整个句子。根据其作用可分为时间、地点、原因、条件、目的、结果、让步、方式和比较等从句。状语从句一般由连词(从属连词)引导,也可以由词组引起。从句位于句首或句中时通常用逗号与主句隔开,位于句尾时可以不用逗号隔开。
比较while/as/when:
1、as/when引导短暂性动作的动词例句:
如:Just as/Just when/When I stopped my car, a man came up to me.
2、当从句的动作发生于主句动作之前,只能用when引导这个从句,不可用as或while。
如:When you have finished your work, you may have a rest.
3、从句表示“随时间推移”连词能用as,不用when或while。
如:As the day went on, the weather got worse.
比较untill/till:
两个连词意义相同,肯定形式表示的意思是“做某事直至某时”,动词必须是延续性的。否定形式表达的意思是“直至某时才做某事”,动词为延续性或非延续性都可以。
正确使用这两个连词的关键之一就在于判断句中的动词该用肯定式还是否定式。
肯定句例句:I slept until midnight. 我一直睡到半夜时醒了。
Wait till I call you. 等着我叫你。
注意:在肯定句中可用before代替:Let's get in the wheat before the sunsets.
否定句例句:She didn't arrive until 6o'clock.
I didn't manage to do it until you had explained how.
1、Until可用于句首,而till通常不用于句首。
例句:Until you told me, I had heard nothing of what happened.
2、Untilwhen疑问句中,until要放在句首。
例句:Until when are you staying? 你呆到什么时候?
注意:否定句可用另外两种句式表示。
1)Not until…在句首,主句用倒装。
例句:Not until the early years of the19th century did man know what heat is.
2)It is not until…that…
状语从句的用种类:
1、时间状语从句:
表示时间的状语从句可由when, as, while, whenever, after, before, till(until), since, once, as soon as(或the moment), by the time, no sooner…than, hardly(scarcely)… when, everytime等引导。
e.g. When I came into the office, the teachers were having a meeting.
He started as soon as he received the news.
Once you see him, you will never forget him.
No sooner had I gone to bed than I went to sleep.
2、原因状语从句:
原因状语从句是表示原因或理由的,引导这类从句的最常用的连词是because, since, as, nowthat(既然)等,for表示因果关系时(它引导的不是从句)为并列连词,语气不如because强。 e.g. He is disappointed because he didn't get the position.
As it is raining, I will not go out.
Now that you mention it, I do remember.
3、地点状语从句:
引导地点状语从句的连词是where和wherever等。
e.g. Sit wherever you like.
Make a mark where you have a question.
4、目的状语从句:
引导目的状语从句最常用的词(组)是so, so that(从句谓语常有情态动词), in order that, in case(以防,以免)等。
e.g. Speak clearly, so that they may understand you.
She has bought the book in order that she could follow the TV lessons.
He left early in case he should miss the train.
5、结果状语从句:
结果状语从句是表示事态结果的从句,通常主句是原因,从句是结果。由so that(从句谓语一般没有情态动词),so…that, such…that等引导。
e.g. She was ill, so that she didn't attend the meeting.
He was so excited that he could not say a word.
She is such a good teacher that everyone admires her.
6、条件状语从句:
条件状语从句分真实性(有可能实现的事情)与非真实性(条件与事实相反或者在说话者看来不大可能实现的事情)条件句。
引导条件状语从句的词(组)主要有if, unless, so(as)long as, on condition that, so(as) far as, if only(=if)。
注意:条件从句中的if不能用whether替换。
e.g. If he is not in the office, he must be out for lunch.
You may borrow the book so long as you keep it clean.
So far as I know(据我所知), he will be away for three months.
You can go swimming on condition that(=if) you don't go too far away from the river bank.
If he had come a few minutes earlier, he could have seen her.
7、让步状语从句:
让步状语从句可由although, though, as, even if(though), however, whatever, whether…or, no matter who(when, what,…)等引导。
注意:as引导的让步状语从句一般是倒装的。
e.g. Though he is a child, he knows a lot.
Child a she is, he knows a lot.
Whatever(=No matter what) you say, I'll never change my mind.
8、方式状语从句:
方式状语从句常由as, as if(though), the way, rather than等引导。
e.g.You must do the exercise as I show you.
He acted as if nothing had happened.
9、比较状语从句:
比较状语从句常用than, so(as)…as, the more…the more等引导。
e.g. I have made a lot more mistakes than you have.
He smokes cigarettes as expensive as he can afford.
The busier he is, the happier he feels.
使用状语从句时要注意的几个问题:
1、在时间和条件(有时也在方式、让步等)从句中,主句是一般将来时,从句通常用一般现在时表示将来。
e.g. We'll go outing if it doesn't rain tomorrow.
I'll write to you as soon as I get to Shanghai.
2、有些时间、地点、条件、方式或让步从句,如果从句的主语与主句主语一致(或虽不一致,是it),从句的谓语又包含动词be,就可省略从句中的“主语+be”部分。
e.g. When(hewas) still a boy of ten, he had to work day and night.
If(you are) asked you may come in.
If(it is) necessary I'll explain to you again.
3、注意区分不同从句:引导的是什么从句,不仅要根据连词,还要根据句子结构和句意来判别。以where为例,能引导多种从句。
e.g. You are to find it where you left it.(地点状语从句)
Tell me the address where he lives.(定语从句,句中有先行词)
I don't know where he came from.(宾语从句)
Where he has gone is not known yet.(主语从句)
This place is where they once hid.(表语从句)
注意:表示“一…就…”的结构 hardly/scarcely…when/before/no sooner…than和as soon as都可以表示“一…就…”的意思。
例句:I had hardly/scarcely got home when it began to rain.
I had no sooner got home than it began to rain.
As soon as I got home, it began to rain.
注意:如果hardly/scarcely或nosooner置于句首,句子必须用倒装结构:
例句:Hardly/Scarcely had I got home when it began to rain.
No sooner had I got home than it began to rain.
主谓一致的概念:
谓语的数必须和主语的人称和数保持一致,这就叫主谓一致。
主谓一致的基本原则:
1)语法一致原则,即在语法形式上取得一致。例如,主语是单数形式,谓语动词也采取单数形式;主语是复数形式,谓语动词也采取复数形式。
例如:The students are very young.
This picture looks beautiful.
2)意义一致原则,即从意义着眼处理一致关系。例如,主语形式虽是单数但意义是复数,谓语动词也采取复数形式;
而有些主语形式虽是复数但意义上看作单数,谓语动词也采取单数形式。
例如:The people in that country are fighting for independence.
The crowd deeply respect their leader.
Three years in a strange land seems a long time.
3)就近原则,即谓语动词的单数或复数形式取决于最靠近它的词语。
例如:Neither hen or I am going to see the film tonight because we are busy.
几对容易混淆词组的一致用法:
1、由“this/thatkind/typeof+名词”作主语,谓语动词用单数形式;而由"these/thosekind/typeof+复数名词”作主语,谓语动词用复数形式。
例如:This kind of apples is highly priced.
Those kind(s) of tests are good.
2、由“a number of,a totalo f,an average of+复数名词”作主语,谓语动词用复数形式;由“the number of,the total of,the average of+复数名词”作主语,谓语动词用单数形式。
例如:A number of students are waiting for the bus.
The number of the students in this university is increasing yearly.
3、one of,the(only) one of的一致用法
例如:This is one of the books that have been recommended.
This is the(only) one of the books that has been recommended.
主谓一致用法点拨:
1、并列结构作主语谓语用复数:
如:Reading and writing are very important.
注意:当主语由and连结时,如果它表示一个单一的概念,即指同一人或同一物时,谓语动词用单数,and此时连接的两个词前只有一个冠词。
如:The iron and steel industry is very important to our life.
典型例题:
The League secretary and monitor___asked to make a speech at the meeting.
A. is
B. was
C. are
D. were
答案:B.
注:先从时态上考虑。这是过去发生的事情应用过去时,先排除A、C本题易误选D,因为The League secretary and monitor 好象是两个人,但仔细辨别,monitor前没有the,在英语中,当一人兼数职时只在第一个职务前加定冠词。后面的职务用and相连。这样本题主语为一个人,所以应选B。
2、主谓一致中的靠近原则:
1)当there be句型的主语是一系列事物时,谓语应与最邻近的主语保持一致。
例如:There is a pen, a knife and several books on the desk.
There are twenty boy-students and twenty-three girl-students in the class.
2)当either…or…与neither…nor,连接两个主语时,谓语动词与最邻近的主语保持一致。
如果句子是由here, there引导,而主语又不止一个时,谓语通常也和最邻近的主语一致。
例如:Either you or she is to go.
Here is a pen, a few envelops and some paper for you.
3、谓语动词与前面的主语一致:
当主语后面跟有with, together with, like, except, but, no less than, as well as等词引起的短语时,谓语动词与前面的主语一致。
例如:The teacher together with some students is visiting the factory.
He as well as I wants to go boating.
4、谓语需用单数:
1)代词each和由every, some, no, any等构成的复合代词作主语,或主语中含有each,every,谓语需用单数。
例如:Each of us has a tape-recorder.
2)当主语是一本书或一条格言时,谓语动词常用单数。
例如:The Arabian Night is a book known to lovers of English.
3)表示金钱,时间,价格或度量衡的复合名词作主语时,通常把这些名词看作一个整体,谓语一般用单数。(用复数也可,意思不变。)
例如:Three weeks was allowed for making the necessary preparations.
Ten yuan is enough.
5、指代意义决定谓语的单复数:
1)在代词what, which, who, none, some, any, more, most, all等词的单复数由其指代的词的单复数决定。
例如:All is right. (一切顺利。)
All are present. (所有人都到齐了。)
2)集体名词作主语时,谓语的数要根据主语的意思来决定。
例如:family, audience, crew, crowd, class, company, committee等词后用复数形式时,意为这个集体中的各个成员,用单数时表示该个集体。
例如:His family isn't very large. 他家不是一个大家庭。
His family are music lovers. 他的家人都是音乐爱好者。
但集合名词people, police, cattle, poultry等在任何情况下都用复数形式。
例如:Are there any police around?
3)有些名词,如variety, number, population, proportion, majority等有时看作单数,有时看作复数。
A number of+名词复数+复数动词。 The number of+名词复数+单数动词。
例如:A number of books have lent out.
The majority of the students like English.
6、与后接名词或代词保持一致:
1)用half of, part of, most of, a portion of等词引起主语时,动词通常与of后面的名词,代词保持一致。
例如:Most of his money is spent on books.
Most of the students are taking an active part in sports.
2)在一些短语,如many a或more than one所修饰的词作主语时,谓语动词多用单数形式。
但由more than…of作主语时,动词应与其后的名词或代词保持一致。
例如:Many a person has read the novel. 许多人都读过这本书。
More than 60percent of the students are from the city. 百分之六十多的学生都来自这个城市
主谓一致知识体系:
主谓一致用法拓展:
1)当everyone,everybody,noone,nobody,anyone,anybody,someone,somebody,everything,anything,something,nothing等用作主语时,其相应的代词一般用单数形式。
例如:If anybody calls, tell him that I'm out.
Something strange happened, didn't it?
2)人称代词与名词的呼应:人称代词I(me),he(him),she(her),it(it) 都是代替前面的单数名词,而they(them),we(us)则是代替复数名词的,you既可以代表单数,也可以代表复数。但表示泛指的时候,用he或one来表示。
例如:If a young person enters a classical music field only for money, he is in the wrong profession.
3)物主代词与名词的呼应:my,our,his,her,its,their要与代替的名词在数上一致。
例如:The welfare department,as well as the other social services,will have its budget cut.
4)反身代词与其所代成分间的呼应。
例如:Many primitive people believed that by eating ananimal they could get some of the good qualities of that animal for themselves.
5)指示代词与所代名词间的呼应:this和that指代单数名词或不可数名词,these和those指代复数名词(those还可以用作先行词,引导定语从句,表示“那些人”)。
例如:She invited all those who had been her former colleagues.
6)much和muchof后接不可数名词,而many和manyof后接可数名词的复数。
例如:There is not much coal left.
A great many of the houses were knocked down by the earthquake.
7)表示量的词后面有的接可数名词,有的接不可数名词。
接可数名词的有:a number of,a rangeof,a series of十复数名词;
接不可数名词的有:a great deal of,an amount of十不可数名词;
既可接可数又可接不可数名词的有:a lot of,a variety of。
例如:1.The government attached a great deal of importance to education.
2.Quiteanumberofwomenappliedforthisjob.
3.The college library has avariety of books.
4.An apple is avariety off ruit.
