第二篇、句法

一、主要句式

(一) 知识概要

定句之分。其中可以分为以下五种:①主语+不及物动词。如:I arrived at six last night.② 主语+及物动词+宾语,如:主语+及物动词+间接宾语+直接宾语,如:Please tell me a story before I go to bed. 这样可加双宾语的句子有buy,tell, give, ask, pass, teach.④ 主语+及物动词+宾语+宾语补足语,如:I found it impossi ble to do it. Please keep the classroom clean and tidy.⑤ 主语+系动词+表语,如:Tom is an American boy. The grass turned green in spring.在初中常见的句型中有There be…句型,表示存在某种事物,如:其be动词的形式要与其后面相近的那个名词相一致。要注意的是这种句型加入助动词后,也要保持be动词,不要换用have,如:There is g在句子结构中要注意主谓一致的问题,即句子的主语与谓语动词要相呼应。要注意的有如下几点:① 用and 连接两个主语时一般应视为复数,但如一人身兼两职时则要用单数谓语动词形式,如:A singer and dancer is coming to our party. a singer and dancer 既歌唱又可舞的演员。而a singer and a dancer 则要译为:一位歌唱家和一位舞蹈家。②有些以s 结尾的名词谓语动词要用单数,如:The news is good (news 为不可数名词)。③ 有量词时应按量词的数量计算;如:有些形单却意为复数的名词,如:这样的词还有Police,如果要讲一个警察时,应讲 a policeman。两个警察为two policemen。又如 a policewoman, two 所有不定代词each,either,neither,one,the other,nobody,

nothing,anyone,anything,someone,something … 要作为单数如:Someone is 在并列句中表示联合关系的连词有:and not only … but also,neither … nor,如: My sister and my parents are going to the cinema。表示转折关系的并列连词有:but 和yet,如:She is a good student, but she didn't pass the final exam. 又如:表示选择关系的连词有:or,either … or,如:Hurry up, or you will be late for school表示因果关系的并列连词有:for,so 如:They studied very hard,so the在初中范围复合句中主要有状语从句和宾语从句(名词性从句)两种,而定语从句(形容词性从句)要在高中讲述,为了使同学阅读文章方便,我们将在下面另一章予以介绍。我们首先来看宾语从句。①在及物动词的后面可以接一个名词来充当宾语,如:I knew the man, 而这时也可以用一个句子来充当宾语,如:这时宾语从句的连接词有that, (that 只在从句中起联接作用,不在句中充当语法成分,既不是主语也不是宾语,所以在口语中常常被省略。如:

whether 它们在宾语从句中只起连接作用,不起语法作用,当作是否讲。从句中有or not 结构时,要用whether, 如:

③what 它在宾语从句中除了作连接词外,还要作主语

或宾语成份,如:作said 的宾语)。又如:I asked him what made him sick (what 在宾语从句中作主语)。④who,它也和what一样,在句中除作连接词外,可以充当句中的成份,如:I know who she is looking for? ⑤whose 如:I want to know whose book this is? ⑥which 如:Do you know which book is 在连接词中还有4个常用的连接副词,①how 它的应用最广,如:how much, how many, how long, how soon, how old …。如:How much does it cost? ②when 它

只是连接时间状语,如:Please tell me when the meeting will begin? ③where 它连接地点状语,如:Where are you from? ④why 它要连接的是原因状语从句,如:The teacher asked why Tom didn't come to school. 在考试中常见到的考点是:宾语从句的时态与主句时态的呼应问题。①主句谓语动词如果是现在时或将来时,宾语从句的时态可以是任何所需要的时态,如:I know he didn't come. 我知道他没来。I know he will come 我知道他明天来。我知道他已去伦敦了。②主句中的谓语动词若是过去时,宾语从句也要用过去时态中的某一种。比如:一般过去时,过去进行时,过去将来时,过去完成时。除了在表达宇宙中的客观真理时,不能用现在时态。如:

状语从句主要有时间状语从句,其连接词有:after,before,when,as,as soon as,until (till),while,since,其中较难掌握的有以下几点:until (till) 直到,在用until 表达时间状语的句子中,主句中的动词是要十分小心去选择。如动词是持续性动词,它要用肯定句,如:I studied hard until 12 o'clock last night. 如果动词是瞬间截止性动词,则要用否定句,如:

由,for,by,before 来引导的时间状语从句。since 引导的时间状语是动作的开始时间,如:I have studied English since 1990而由by 引导的时间状语通常是动作的结束时间,如:而before 则多用于完成时,ago 则多用于一般过去时,如:He had finished his work before twelve

在状语从句中用一般现在时或一般

过去时表示将来。它们可能是主句用一般将来时,从句用一般现在时,如:If it rains, they won't go to the park 也可以主句是一般过去时,从句用一般过去进行时,如:

考试中常见的考点有:要学

生区别是条件、时间状语从句还是宾语从句,因在宾语从句中该用什么时态用什么时态,如:I want to know if he will come here tomorrow在宾语从句中的条件状语从句与主句的关系,如:在原因状语从句中主要是①because,应译为"因为"。它表达的因果关系最强,如:He didn't pass the exam

since 应译为"既然",如:Since you were ill

as 应译为"由于",如:As it is too hot

与as 所表达的因果关系远比because 弱得多。而for 表达的因果关系最弱。它不能用于句首,如:He studies hard, for he wants to go to 在比较状语从句中有同级比较as … as,如:This book is as good as that 要注意的有两点:①as … as 中间要用原级而不是比较级。②用形容词还是副词,如:而其否定句为not as (so) … as,如:They didn't work so hard as we did, 而不同级比较用比较级加than, 如:He is younger than I 要注意的是表示"越来越"这一概念时有两个句型:①比较级+and+比较级,如:

l is becoming more and more 定冠词the +比较级+the +比较级,如:The harder you study, the

方式状语中要注意的是as (连词)与like (介词)的区别。as 作为连词其后接从句,如:但后面的句子常作省略,如:Please do it as 而like 是介词,其后要接的是宾语,如:Please do 结果和目的状语从句主要有so … that,so that,in order that等几种用法。①用在单数可数名词前,so +形容词+a +名词+that,如:She is so beautiful a girl that everyone 或用such +a +形容词+名词+that, 如:She is such a beautiful girl

在不可数名词或可数名词复数前只能用such,如:It is

又如:They are such good players that they should win the game. ③在much,many,few,little 之前只能用so,如:I

so … that 之间只有形容词时,则不能用such,

如:so that 其后接从句,如:I got up earlier so that

(二)正误辨析

[误]

[正]

[析]作主语的名词、代词或不定式、动名词,它们往往要带有修饰词,这些词可能是形容词,也可能是短语,但谓语动词还是要取决于这个主语的数,要记住的是一个名词不可能在同一句中作两个不同的语法成份,如:book 作了of 的介词宾语则不可能再作主语了。

[误]

[正]

[析]不定式作主语应该看作单数主语。

[误]

[正]Wh

[析]从句作主语一定要按单数主语看待。

[正]

[误]

[析]形容词+定冠词表示一类人,谓语动词应用复数,如:The young are very interested

[误]

[正]The s

[析]本句应译为:校长兼作家就要来了。而The school master and the writer are 则要译为:校长和一个作家要来了。在英语表达法中确实有The girl and boy are

这应译为:一个女孩,一个男孩在操场上玩。因为不可能这样两个概念作用在一个人身上。又如:夫妻二人。

[误]You o

[正]

[析]由or 连接的两个主语应以离谓语动词近的那一个计算其数。这样的用法还有either … or,neither … nor,not only … but also 也有人称作"就近原则"。

[误]

[正]

[析]真正的主语是the teacher,而with 短语是伴随状态,不影响主语的数。

[误]

[正]

[误]

[正]

[误]

[正]

[析]英语中有些名词只有复数形式,如:glasses 眼镜,shorts 短裤等。如没有量词在前时,要用复数谓语动词,但有了量词之后则要按量词的单复数计算。

[误]

[正]One of the boys is going to take part in

[析]One of 结构应以one 来计算主语的数。

[误]

[正]

[误]

[正]

[析]在小于1的数量词作主语时,如:23,80%,0.35… +of +名词,这时主语的数应按of 后面的名词计算。如果名词是不可数名词或可数名词单数,则谓语动词要用单数,如名词是复数则要用复数谓语动词。

[误]

[正]

[误]

[正]

[析]each,either 其后都要加单数名词,而both 后要加复数名词。如:each,either,

another,little,a little,much等作主语时,谓语动词全部要用单数形式。

[误]

[正]

[析]each 作同位语时,不影响句子的主语。

[误]

[正]

[析]everyone,someone,everybody … 在作主语时都不能加of 结构。

[误]Girls like dancing very much,

[正]Girls like dancing very much,

[析]few 虽然含意上是"几乎没有",但作主语时仍要当作复数。

[误]

[正]

[析]the number of 意为:某某的数字是…… 如:the number of students 学生人数,the number of players 运动员人数。不论数字如何都应看作单数。而a number of 与many 意思相同,其后加可数名词复数,谓语动词用复数形式。如:A number of students are

[误]

[正]

[误]

[正]

[析]the rest of 的用法与2/3,一半,80%+of 的结构一致,of 后面为可数名词复数时用复数谓语动词,为不可数名词或可数名词单数时用单数谓语动词。这样用法还有

lots of,a lot of,plenty of。

[误]

[正]

[析]有些以s 结尾的名词要用作不可数名词,它们是:news,physics,mathematics,thanks,

[误]

[正]

[析]Chinese 作为中文来讲是单数名词,但作为中国人讲是单复同形的名词。如:one

Chinese,two Chinese … 而The Chinese =The people of China 要用复数谓语动词。[误]This dictionary is too expe

[正]

[析]表示一段时间,一笔金钱,一段距离,都应看作单数名词。

[误]

[正]Who is going to take part in our footbal

[析]用who 提问时,习惯上用单数谓语动词,但which 则要视其情况而定,如:which are better these shoeses or those shoes? 又如:which is better this one or that one? [误]

[误]

[正]

[正]How hot the

[析]感叹句是用来表达说话人的喜怒哀乐的感情。它由what 与how 作句子的开始,判定是用what 还是用how 的最好办法是将它们换为陈述句,比如:What the hot weather it is! 应转换为:那么句子的起点是单词it。再来看感叹句中it 前有不可数名词weather,则只能用what。再看第二句How hot the weather is! 转为陈述句时为:The weathe这时句子的开始单词为the weather,再来看感叹句在the weather 前只有形容词,所以应用how。至于是用what a 还是what 要看名词的具体情况而定,单数可数名词加what a 其余的加用what。

[误]We have to sing this,

[误]We have to sing this,

[正]

[析]在反意疑问句中除了标准的一些常规外,有一些例外:

Let's go home,shall we?

Let us go home,

She had to leave,

Do your homework at once,

There is not much good news in today's newspaper,

Neither of them are right,

I think he will

think 后的宾语从句,与其他宾语从句不一样,在初中只有这样一个较特殊的词。这样的句子的反意疑问句的主语要用宾语从句中的主语,其助动词要用宾语从句的助动词,而肯定还是否定要看主句谓语动词而定,如:I don't think he is coming to our party,

[误]

[正]

[析]宾语从句中一律要用陈述语序,而不用疑问语序。

[误]-

-

[正]-

-

[析]nor,neither 用在简答否定句中时要采用倒装语序。在肯定句的简答句中则要用so,如:I do my homework very quickly,

[误]

[正]

[误]

[正]

[析]在there,here 打头的句子中,如果主语是名词,则要采用倒装语序;如果是人

称代词则用一般语序。

[误]

No,

[正]

No,

[析]我不这样想,可用但hope 的否定简答句只能用这是习惯用法。但这两个词的肯定简答句形是一样的,如:I think so

[误]

[正]

[析]It 这里的语法作用是形式主语,而真正的主语是后面的不定式。形式主语和形式宾语都要用it 而不能用that,如:在这句中是think 的形式宾语。

(三)例题解析

There ___.

A .is B. are C. has D. have

[答案]

[析]There be 句形中的be 动词要看其后面离它最近的名词而定,如:There are two

Could you tell me ___

Mrs King lives where

[答案]

[析] 宾语从句中的疑问句要用陈述语序。

[答案]

[析] 前句是肯定句,后面反意疑问句要用否定句,同时 came 为过去时态,所以应用

It's getting cloudy , ___

isn't it

[答案]

[析] 要区分's 是 has 还是 is , 这里由 getting 得出's 是is 。

___ keep me waiting so long .

Not to

[答案]

[析] Don't + 动词原形为祈始句的否定句。

Mr Green hasn't been to Beijing, ___

didn't he

[答案]

[析] 此句 has 是助动词与过去分词构成现在完成时态。

You have your lunch at school, ___

[答案]

[析]这里的have 是实意动词"吃",而不是助动词。

___sunny day! Let's go out for a walk.

What

[答案]

[析]这个感叹句是个省略句,其真实的句子应为

- Can you tell me ___-

where your

[析]由neither … nor … 作连接词作主语时,其谓语动词要与相临近的那个主语相呼应。

How

[答案]

[析]因food 为不可数名词。

___

Have

[答案]

[析]这是there be 句型的疑问句。

Could you tell me ___

[析]could 用于现在时疑问句表达了口气的委婉,并不是过去时态。且宾语从句要用陈述语句。

- ___

- Yes,But it's going to be fine soon,

What

[答案]

[析]weather 为不可数名词。

- Could you tell me ___

- Yes,They ___

where were the twins ,

where the twins are , have gone

where the twins were , have gone

[答案]

[析] L et's go …, shall we? Let us go …, will you?这是两个特殊的反意疑问句。

Joan's short , ___

doesn't she

[答案]

[析] 在此句中应视's 为is ,而不是 has 或 was 。

I don't know ___ to read the word .

how

[答案]

[析]因不定式to read 中的read 是及物动词,已有自己的宾语the word,所以应用疑问副词how。

He didn't go to school,___he was ill.

so

[答案]

[析]这里是表示因果的关系,从句表示原因,所以用for,放于句尾,且常常前面有一个逗号。so 引起的是结果状语从句,如:He was only twelve,so he couldn't join the

The young woman can hardly ride a bike,___

can

[答案]

[析]hardly 为否定词,所以应视此句为否定句。其后的反意疑问句应用肯定句。

is he

[答案]

[析]never 也是否定词,所以应将句子看作否定句。

Mother said to him,"Don't ___on football.

spend too many t to spend too many time

[答案]

[析]time 作为"时间"讲为不可数名词,应用much 来修饰。当作"次数"讲是可数名词,如three times 三次,而Don't … 这一句是祈使句的否定句。

afternoon.

___ change much if people leave things as they are .

do

didn't

[答案]

Li Mei read the newspaper to the granny,___

wasn't she

[答案]

(完整版)英语的五大基本句型

英语的五大基本句型 同一个词类可以在句中充当不同的成分,同一个句子成分也可以由不同的词类来担任。 句子的组成成分叫句子成分。在句子中,词与词之间有一定的组合关系,按照不同的关系,可以把句子分为不同的组成成分。句子成分由词或词组充当。 现代汉语里一般的句子成分有六种,即主语、谓语、宾语、定语、状语和补语。英语的基本成分有六种:主语(subject)、谓语(predicate)、表语(predicative)、宾语(object)、定语(attribute)和状语(adverbial)。 英语句子成分中,有些具有形态标志。如第一人称代词作主语就用主格“I”,作宾语用宾格“me”,作定语用所有格“my”。这些形态变化对分析辨认成分很有帮助。 汉语与英语就句子成分表面上看来差不多,实际上有不少差别。例如: Xiao Li went to bed as soon as he came home. 小李回家后, 立刻就睡觉了。 I'll go when I have had my dinner. 我吃了饭就去。 在英语中,同一个主语在第二次出现时不能省略,必须把每个谓语所陈述的对象都表示出来。而在汉语中,同一个主语在句中第二次出现时,就可以省略。如例(1)中,汉语说“小李回家后立刻就睡觉了”,省去了第二个分句的主语,倒可以避免造成误解。若将第二次出现的主语补出来,说成“小李回家后,他立刻就睡觉了”。听的人反而可能把那个“他”误会成另一个人。 把句子的各个成分搞清楚,也就是把句子各部分的关系搞清楚。做到这一点,才可以准确地理解句子的意思或造出结构正确、意思明白的句子。有一点要注意,在分析句子结构时,应该抓住主要成分。我们分析句子结构,划分句子成分无非是为了理解,或者是为了造句。各种语言有各自的规则、各自的习惯,而且语言是很灵活的东西,发展过程也很复杂,很难把语法的现象都做出明确、统一的解释来。在使用一种语言时,语法应让位于习惯。符合习惯的,有时尽管不符合语法,也是正确的。 英语句子有长在短,有简有繁,从现象看,似乎千变万化,难以捉摸,但从实质看,可以发现其内在联系,找出其共同规律。英语句子的基本结构可以归纳成五种基本句型及其扩大、组合、省略或倒装。掌握这五种基本句型,是掌握各种英语句子结构的基础。 英语五种基本句型列式如下: 基本句型一:S+V(主+谓) 基本句型二:S+V+P(主+谓+表) 基本句型三:S+V+O(主+谓+宾) 基本句型四:S+V+o+O(主+谓+间宾+直宾) 基本句型五:S+V+O+C(主+谓+宾+宾补) 基本句型一 此句型的句子有一个共同特点,即句子的谓语动词都能表达完整的意思。 这类动词叫做不及物动词,后面可以跟副词、介词短语、状语从句等。 S+V(不及物动词) 1. The sun │was shining. 2. The moon │rose. 3. The universe │remains. 4. We all │breathe,eat, and dri
