动词

一、被动语态

1、被动语态的构成:

语态是动词的一种形式,用来说明主语和谓语动词间的关系,英语动词有两种语态:主动

语态和被动语态。被动语态由“be+过去分词”构成,在句中be动词要有人称和数的变化。

【口诀】被动语态be字变,过去分词跟后面。注意:只有及物动词才有被动语态。

2、被动语态的用法:

【口诀】谁做动作不知道,说出谁做没必要;承受者需被强调,被动语态运用到。

如:---We have to look after the dog. ---The dog has to be looked after by us.

③含有宾语补足语的被动语态:

含有宾语补足语的句子,宾语变为主语后,宾语补足语改为主语补足语,原来的位 置一般不变。

如:---We keep food cold in the fridge.

---Food is kept cold in the fridge.

注意:主动句中的宾语补足语如果是不带to 的不定式,在变成被动句的主语补足语时,to 不能省去。

如:---She heard him sing a song just now.

---She was heard to sing a song just now.

二、过去完成时

1、概念:表示过去的过去

2、过去完成时:即过去的过去所发生的事情!

3、构成:主语+had +过去分词。

4、用法:

①表示过去某一时刻之前已经完成的动作,常与由b y ,before 引导的时间状语连用。 如:We had learned 5000 words by the end of last month.

到上个月底为止我们已经学了五千个单词

I had finished the composition before supper.

晚饭前我就已经把作文写完了

②表示过去某一动作前已完成的动作,常与when ,before 等连词引导的时间状语从句连用。 如:When I woke up it had already stopped raining.

我醒来的时候雨就已经停了

I hadn ’t learned any English before I came here.

我来这儿之前没学过英语

③用于宾语从句或间接引语中。

如:I wondered who had taken the umbrella without permission.

我想知道谁不经允许就把雨伞拿去。

He told me that he had passed the exam.

他告诉我他已通过考试。

三、情态动词

1、概念:

情态动词是一种本身有一定的词义,但要与动词原形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。

2、分类:

①只做情态动词:m u s t ,c a n (c o u l d ),m a y (m i g h t ), ②可做情态动词又可做实意动词:n e e d ,d a r e ③可做情态动词又可做助动词:s h a l l (s h o u l d ),w i l l (w o u l d ) ,o u g h t t o

④具有情态动词特征:h a v e (h a d ,h a s ) t o ,u s e d t o ⑤情态动词表猜测

NIZ LUWENJIE LUWENJIE LUWENJIE LUWENJIE LUWENJIE LUWENJIE LUWENJIE LUWENJIE NIZ 好久不见 别来无恙

3、位置:

情态动词有一定的词义,但并不完整,必

须与动词原形一起构成谓语。

4、用法:

情态动词+行为动词原形

首先它是动词,而且不同于行为动词,行为动

词表示的是可以通过行为来表达的动作,而情态

动词只是表达的一种想法。

5、功能:

助动词主要有两类:基本助动词和情态助

动词。基本助动词有三个:d o , h a v e 和b e ;情态

助动词基本的有十四个:

may, m i g h t ; c a n , c o u l d ; w i l l , w o u l d ; s h a l l ,

s h o u l d ; m u s t ,

n e e d , d a r e , u s e d t o , o u g h t to.h a d b e t t e r ,

6、c a n 和c o u l d 的用法:

①表示能力或客观可能性,还可以表示请求

和允许。

②表示惊异、怀疑、不相信的态度。(主要

用在否定句、疑问句或惊叹句中)

【注意】c o u l d 可表示请求,语气委婉,主

要用于疑问句,不可用于肯定句,答语用c a n (即

c o u l

d 不能用于现在时态的简略答语中)。 c a n 表

示能

力时,还可用b e a b l e t o 代替。

宾语从句

在复合句中用作宾语的从句叫宾语从句。

我在等一个可以陪我走很久的人

1.语序:

无论主句是陈述句还是疑问句,宾语从句都必须使用陈述语序,即“主句+连词+宾语从句(主

语+谓语+……)”句式。

1)连接词+谓语。连接词在从句中作主语。常见的连接词有: who,what,which等。

2)连接词+名词+谓语。连接词在从句中作主语的定语。常见连接词有:whose,what,which,

how many,how much等。

3)连接词+主语+谓语。连接词在从句中作宾语、状语或表语。常见的连接词有:who(m),what,

which,how many,how much, when,why,how,where,if /whether(在句中不充当任何

成分)等。

4)连接词+名词+主语+谓语。连接词在从句中作宾语或表语的定语。常见的连接词有:what,

which,how many,how much,how等。

2.连接词:

1)陈述句充当宾语从句时,用that引导,that无词义,在口语或非正式文体中常省略

2)一般疑问句充当宾语从句时,用if或whether引导,意为“是否”

①具选择意义,有or或or not时,直接与or not连用时,用whether(if…or not也可使用)

②在介词之后用whether

③在不定式前用whether

④whether置于句首时,不能换用if

⑤引导主语从句和表语从句时宜用whether

NIZ LUWENJIE LUWENJIE LUWENJIE LUWENJIE LUWENJIE LUWENJIE LUWENJIE LUWENJIE NIZ

⑥若用if会引起歧义时,则用whether

3)如果宾语从句原来是特殊疑问句,只需用原来的特殊疑问词引导

别告诉他我还想他

3.时态:

1)如主句的谓语动词是一般现在时,从句的谓语动词可根据需要,选用相应的任何时态。

2)如果主句的谓语动词是过去时,宾语从句的谓语动词只可根据需要,选用过去时态即

一般过去时、过去进行时、过去将来时或过去完成时的某一种形式。

3)如果宾语从句所表示的是客观事实、普遍真理、自然现象或习惯性动作等,不管主句

用什么时态,从句时态都用一般现在时。

4.注意:

if和when既可以引导宾语从句,也可以引导状语从句,应注意它们在两种从句中的意思和用法的不同。if和when引导宾语从句时,分别意为“是否”和“何时”,其时态应和

主句时态相呼应;它们引导状语从句时,意思分别为“如果,假如”和“当……时候”,当

主句时态是一般将来时时,其时态用一般现在时。它们常常放在含有状语从句和宾语从句的

题干中进行综合考查。

定语从句

详细的定语从句讲解 : 定语从句是由关系代词和关系副词引导的从句,其作用是作定语修饰主句的某个成分,定语从句分为限定性和非限定性从句两种。状语从句分为时间状语从句,结果状语从句,让步状语从句,原因状语从句,条件状语从句以及行为方式状语从句。名词从句包括主语从句,宾语从句,表语从句和同位语从句及there be 句型。

一、 限定性定语从句:

1. that 即可代表事物也可代表人,which 代表事物;它们在从句中作主语或宾语,that 在从句中作宾语时常可省略关系词,which 在从句中作宾语则不能省略。而且,如果which 在从句中作“不及物动词+介词”的介词的宾语,注意介词不要丢掉,而且介词总是放在关系代词which 的前边,但有的则放在它原来的位置

2. which 作宾语时,根据先行词与定语从句之间的语义关系,先行词与which 之间的介词不能丢

3. 代表物时多用which ,但在带有下列词的句子中用that 而不用which ,这些词包括all, anything, much 等,这时的that 常被省略

4. who 和whom 引导的从句用来修饰人,分别作从句中的主语和宾语,whom 作宾语时,要注意它可以作动词的宾语也可以作介词的宾语

5. where 是关系副词,用来表示地点的定语从句

6. when 引导定语从句表示时间

〔注〕值得一提的是,表示时间“time"一词的定语从句只用when 引导,有时不用任何关系代词,当然也不用that 引导

7. whose 是关系代词,修饰名词作定语,相当于所修饰成分的前置所有格

8. 当从句的逻辑主语是some, any, no, somebody, anybody, nobody, something, anything, everything 或nothing 时,常用there is 来引导

二、非限定性定语从句:非限定性定语从句的作用是对所修饰的成分作进一步说明,通常和主句间用逗号隔开,将从句拿掉后其他部分仍可成立。

1.which 引导的非限定性定语从句来说明前面整个句子的情况或主句的某一部分

2.引导限定性定语从句时,that 有时相当于in which, at which, for which 或at which

3.有时as 也可用作关系代词

4.在非限定性定语从句中,不能用that ,而用who, whom 代表人,用which 代表事物

三、定语从句结构错误:

1. 缺关系词

2. 从句中缺成分

NIZ LUWENJIE LUWENJIE LUWENJIE LUWENJIE LUWENJIE LUWENJIE LUWENJIE LUWENJIE NIZ 故事很长 只有风听我讲

在英文中,有两种定语从句:限定性定语从句与非限定性定语从句。这两种定语从句在其功能和形式方面都有明显的区别:

①限定性定语从句限定性定语从句与主句的关系很紧奏,对其先行词起限定、修饰的作用。如果将其去掉,会影响句子意思的完整性;有时甚至于引起费解、误解。

②非限定性定语从句非限定性定语从句在形式上就与主句很松散,它与主句之间有一个逗点","隔开;它对其先行词没有限定、修饰的作用,只起补充、说明的作用。有时也用它来对全句进行补充、说明。即使将其去掉,也不会影响句子意思。由于上述原因,非限定性定语从句在表达意思方面也有别于限定性定语从句。另外,非限定性定语从句在中文译文里,我们往往将其作为一个分句处理,而不把它作定语翻译。

四、定语从句的讲解:

定语从句在句中做定语,修饰一个名词或代词,被修饰的名词,词组或代词即先行词。定语从句通常出现在先行词之后,由关系词(关系代词或关系副词)引出。

1.关系代词所代替的先行词是人或物的名词或代词,并在句中充当主语、宾语、定语等成分。关系代词在定语从句中作主语时,从句谓语动词的人称和数要和先行词保持一致。 ①who/that 在从句中作主语;whom/that 在从句中作宾语

②Whose 用来指人或物(只用作定语, 若指物,它还可以同of which 互换)

③which, that 它们所代替的先行词是事物的名词或代词,在从句中可作主语、宾语

2.关系副词可代替的先行词是时间、地点或理由的名词,在从句中作状语。

①when, where, why 相当于"介词+ which"结构,常和"介词+ which"结构交替使用

②that 代替关系副词 ,that 可以用于表示时间、地点、方式、理由的名词后取代when, where, why 和"介词+ which"引导的定语从句,在口语中that 常被省略

构词法

故事不够动人讲故事的人却总流泪1.构词法(Word Formation):

B.派生词(Derivative)

定义:由词根利用前缀或后缀派生而成的词称为派生词(亦称转成语)

C.合成词(Compound Words)

定义:由两个或两个以上独立且语义不同的词结合成一个表达新语义和语词功能的词称为合成词

2.词是什么?

“词”的英语是“Word”。依据词典“Word”可译为“语言、言、话、字、文字、词”

等。人类在学习一种语言时最基本的两件事就是认识词和使用词来表达思想。

3.那么“Word”是什么?

从表达思想来说。大凡人要把心中所感觉到的和所想的表达出来时,一个共通的表达模式就是“举

出主题并说明他”。这种表达模式我们叫“一句话”,在语言学上称为句子。

定义:

词、短语、从句等称句子组成要素。词是句子的组成要素中不能再细分的最小表意单位。

构词法:

英文词和中文词的最大不同点在于中文词是属于象形文字语系,字形是固定不变,而且是一字一音;英文词是属于符号文字语系,其字形(拼写法)须配合语意和句意表达的条件并受其约束,同时有一字一

音、一字二音等。

转化法:

把一个词从一种词类转化为另一种的方法称为转化法

合成法:

两个或两个以上的词结合成一个新词的方法称作合成法。

派生法:

由词缀(分前、后缀)和词根相结合构成单词的方法。大多数词缀都有一定的含义。

比较级使用than的常见语法难点

一、后接人称代词用主格还就是宾格 由于than既可用作连词也可用作介词,所以当后接人称代词时,可用主格也可用宾格。通常认为在正式文体中多用主格,在口语或非正式文体中多用宾语。如: Everyonehere is tallerthan I [me]、这儿得每一个人都比我高。 Her sister swims faster than she[her]、她姐姐游泳比她快。 但就是,若人称代词之后跟有动词,则只能用主格。如: Everyone here is tallerthan I am、这儿得每一个人都比我高。 Her sister swimsfaster than shedoes、她姐姐游泳比她快。 注意:有时用主格或宾格会导致意思得变化。比较: I loveyou more thanhe (likesyou)、我比她更爱您。 Ilove you more than (he likes)him、我爱您胜过爱她。 二、后接动词用不定式还就是动名词 1、当连接两个非谓语动词时,通常应使用一样得形式。如: Itismuch easier to getinto debt than to getout of it、借债容易还债难。 He likes playing chess more thanwatching TV、与瞧电视相比,她更喜欢下棋。 比较: He thinks it is saferto drive himselfthan(to) let me drive、 =He thinksthat drivinghimself is saferthanletting medriv e、她认为她自己开车比让我开车要更安全些。 2、若不就是连接两个非谓语动词,则其后出现得动词通常用动名词形式(虽然也可用不定式,但不如用动名词普通)。如: There are worse calamitiesthan failing your drivingtest、比起您驾驶考试不合格来说,更大得灾难还多着呢。 Nothing givesme more pleasure than listeningto Mozart、再没有比听莫扎特得乐曲更让我高兴得事了。 Nothing is moreunpleasant than finding[tofind] insects in your bath、最使人不快得就是在浴室里发现有虫子。 三、引导比较状语从句得时态问题 若than引导得比较状语从句与主句动作不一致,可以根据情况使用适当得时态形式。如: He drivesfaster than he did a year ago、她开车比一年以前快了。 Thehouse is rather bigger than wethought、这所房子比我们想得大得多。若主句为将来时,than引导得从句可用现在时态表示将来,也可直接使用将来时态。如: We'll probably drive faster than you do[will]、我们开车可能会比您们快。四、引导比较状语从句得倒装问题 than引导比较状语从句时,从句语序通常不需倒装,但在正式文体中,有时也可倒装。如: City dweller havea higherdeath rate thancountry people do、 =City dweller have a higherdeath rate thandocountrypeople、城市居民死亡率比农村居民高。 五、引导比较状语从句且在从句中充当成分 有时可引导一个从句并在从句中充当句子成分(主语、宾语、表语),为便于理解,有时可视为than后省略了what: We don't want to domorethan is necessary、我们不想做不必要得事情。

英语时态讲解 【注】构成时态的助动词be (is, am, are), have (has), shall, will 等需根据主语的变化来选择。时态是英语中一个重要的语法范畴,它表示不同时间发生的动作或存在的状态以及动作发生或存在的方式。动作发生的时间可分为现在、过去、将来和过去将来四种形式,动作发生的方式可分为一般、完成、进行和完成进行四种形式。将时间形式和动作方式结合起来,就构成了以下 英语的时态是靠动词的变化和时间状语来表达的。英语中的时态共有十六种,但是常考的或较常用的只有9种。要掌握英语的时态和语态,必须掌握好英语中的助动词(do, be, have)和时间状语这两个核心问题。 1、一般现在时 主要用来表示人、事物的现在状况和特点;表示经常或习惯性的动作,句子中常有often, always, from time to time 等时间状语;表示客观规律和永恒真理等。 H e usually goes to work at 7 o’clock every morning. 他每天7点上班。 2、现在进行时 表说话时或目前一段时间内正在进行的活动:或表感情色彩,加强语气。与频率副词,如always,constantly,continually,again等连用表示说话人的某种感情色彩(赞叹、厌烦、埋怨等)。 We are having English class.

我们正在上英语课。 3、现在完成时 表示动作发生在过去,完成在过去,但强调与现在情况仍有联系,其结果或影响仍存在。 They have lived in Beijing for five years. 他们在北京已经住了5年了。 4.一般过去时 表在过去某个特定时间发生且完成的动作,或过去习惯性动作,不强调对现在的影响,只说明过去。常跟明确的过去时间连用,如:yesterday; last week; in 1945, at that time; once; during the war; before; a few days ago; He used to smoke a lot. 他过去抽烟比较厉害。 5. 过去进行时 表示过去某个时间点或某段时间内正在发生的动作。 Beijing was hosting the 29th Olympic Games in August 2008. 在2008年8月,北京正在举行29届奥运会。 6. 过去完成时 表示过去某个时间之前已经完成的动作,即过去完成时的动作发生在“过去的过去”,句中有明显的参照动作或时间状语,这种时态从来不孤立使用( before, after, by, up till ) They finished earlier than we had expected. 他们提前完成了(工作)。 7. 一般将来时 表在将来某个时间会发生的动作或情况。常和tomorrow, next year, in 2008等表示将来的时间状语连用。 I am leaving for Beijing tomorrow. 我明天就要离开北京。 8、将来进行时 表将来某个时间正在发生的动作,或按计划一定会发生的事情。 I’ll be doing my homework this time tomorrow. 明天这会我正在写作业。 9、将来完成时 表在将来某时刻之前业已完成的事情,时间状语非常明显。常用的时间状语一般用by+将来的时间。如:by the end of this year, by 8 o’clock this evening, by March next year以及由by the time…, before或when等引导的副词从句。 By the end of next month, he will have traveled 1000 miles on foot. 到下个月底,他步行将达到1000英里。 英语共有十六个时态、四个体。(注:四个体为——一般、进行、完成、完成进行。) 英语中的四个体相当于法语、西班牙语以及所有印欧语系罗曼语族中的式,如:直陈式,命令式等。

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。口诀:情态动词变被动,情态加be 加“过分”,原来带to 要保留。 如:---We have to look after the dog. ---The dog has to be looked after by us. ③含有宾语补足语的被动语态: 含有宾语补足语的句子,宾语变为主语后,宾语补足语改为主语补足语,原来的位 置一般不变。 如:---We keep food cold in the fridge. ---Food is kept cold in the fridge. 注意:主动句中的宾语补足语如果是不带to 的不定式,在变成被动句的主语补足语时,to 不能省去。 如:---She heard him sing a song just now. ---She was heard to sing a song just now. 二、过去完成时 1、概念:表示过去的过去 2、过去完成时:即过去的过去所发生的事情! 3、构成:主语+had +过去分词。 4、用法: ①表示过去某一时刻之前已经完成的动作,常与由b y ,before 引导的时间状语连用。 如:We had learned 5000 words by the end of last month. 到上个月底为止我们已经学了五千个单词 I had finished the composition before supper. 晚饭前我就已经把作文写完了 ②表示过去某一动作前已完成的动作,常与when ,before 等连词引导的时间状语从句连用。 如:When I woke up it had already stopped raining. 我醒来的时候雨就已经停了 I hadn ’t learned any English before I came here. 我来这儿之前没学过英语 ③用于宾语从句或间接引语中。 如:I wondered who had taken the umbrella without permission. 我想知道谁不经允许就把雨伞拿去。 He told me that he had passed the exam. 他告诉我他已通过考试。 三、情态动词 1、概念: 情态动词是一种本身有一定的词义,但要与动词原形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。 2、分类: ①只做情态动词:m u s t ,c a n (c o u l d ),m a y (m i g h t ), ②可做情态动词又可做实意动词:n e e d ,d a r e NIZ LUWENJIE LUWENJIE LUWENJIE LUWENJIE LUWENJIE LUWENJIE LUWENJIE LUWENJIE NIZ 好久不见 别来无恙
