并列结构

两个或两个以上意义相关、层次相同、句法功能也相同、并由并列连词或其他并列手段连接起来的语法结构序列叫做并列结构。

1. 并列结构的各种形式

1)词与词的并列 you and me

2)词组与词组的并列 a teacher and a student

3)分句与分句的并列 you can go or you can stay with us.

2. 并列结构的连接手段

1)并列连词

2)标点符号

3.并列结构的插入语

在最后一个项目之前插入一个词语,使这个项目处于更加突出的地位。

4.并列结构的对称组合

成对组合的办法使整个结构更加紧凑。

3. 并列连词的意义和用法

1.以and为代表的表示语义引申的并列连词

and, both…and, not only… but also, not…nor, neither…nor等。这一类并列连词在语义上表示其连接的成分是对前项的补充和引申,包括肯定和否定两种意义的引申。

And除表示语义增补外还有其他意义.还有一些and连接的语法结构形似并列结构实际并非并列结构.

Eg. This room is nice and warm. = ( nicely warm.) I?ll go and see my friend. = ( go to see) 2.以or 为代表的表示选择的并列连词

这类连词包括or和either…or

3.以but为代表的表示语义转折和对比的并列连词

这类连词包括but, not… but, while, whereas, only, yet.

4. 补充说明:

1) both…and 只连结成分不连接句子;只连对等结构

2) not only …but also连结成分和连接句子;只连对等结构

Eg.

Not only I but also he will take part in the meeting.

Not only did he help me, but also he sent me home.

Eg.

Either you or I am going to shanghai.

He can either stay at home or leave.

He has either gone to the movies or ( gone to ) the theatre.

4) neither …nor连结成分和连接句子;连对等结构或不对等结构

专四语法重点总结 存在句(There be) 可可英语| vicki 上一期 下一期

存在句(There be)

存在句的结构特征

存在句的结构模式是:

There + be + NP + Locative Expression (+ Temporal Expression)

存在句的引导词

There在句中位于主语位置,实义主语是随后的名词词组,There起形式主语的作用,在疑问句中, 它和操作词倒装。注意存在句的引导词There和句首状语There的区别。

存在句的实义主语

实义主语的名词词组通常是非确定特指,即通常带有不定冠词、零冠词及其他非确定意义的限定词, some, any, many, much, a lot of, enough, little…基本句型凡带有非确定特指的名词词

组, 一般都可用There 存在句转化。

存在句的谓语动词

存在句的谓语动词主要是动词be的某种形式, 分限定形式和非限定形式。

限定形式:一般现在时、一般过去时、现在完成体、过去完成体和情态助动词+不定式。除be外, 某些表示存在意义的不及物动词如:exist, remain, occur, stand, lie.等,能用于there存在句。地点状语前移,there可省。

Eg.

There can be very little about his guilt.

There are many desks in the classroom.

There used to be a hospital round the corner.

There appears to be no doubt about it.

There stands a house behind the tree.

Behind the tree (there )stands a house.

专四语法重点总结 存在句的非限定形式 可可英语| vicki 上一期 下一期

存在句的非限定形式

1)存在句的非限定形式

there to be 和 there being结构

2)there to be 和 there being结构用法与区别

there to be:作for 介词补语

作动词(except, want, like, prefer, hate…)的宾语

eg.

They planned for there to be another meeting

Members like there to be plenty of choice.

there being : 作除for外的介词的补语

作主语和状语

eg.

John was relying on there being another opportunity.

There being a bus stop so near the house is a good advantage.

存在句的非限定形式与限定形式的转化

eg. For there to be so few people in the street was unusual. = It was unusual that there were so few people in the street.

专四语法重点总结 It 句型(上) 可可英语| vicki 上一期 下一期

It 句型

1. Basic structure:

There + be + subject + adverbial

2. Non-finite structure

There to be --------- for ; Verb

There being ---------in,on….; noun; adverbial

There being a lawn extends from the river to the house.

There is a lawn extending from the river to the house.

There extends a lawn from the house to the river.

From the house to the river lies a lawn.

From the wall comes the voice of the doctor.

It:

1. Reference it:

Beijing is a big city. It is the capital of China.

2. Non-reference it

A. Empty it

B. Anticipatory it

C. Cleft it

It 句型包括由“非指代性it”作型式主语的三种句子:第一种是以it作形式主语的表示时间、距离、天气等意义的句子;第二种是以it作先行主语的句子;第三种是以it作引导词的分裂句。

Empty it

虚义it是一种非指代性it,以区别于人称代词it,常用作没有具体意义的主语,出现于表示气候、天气、温度、时间、地点、距离等意义的句子中。也用来表示一般的笼统的情况。也用于一些结构及习惯语中。

Eg.

It?s fine today, isn?t it.

It was dull when Mary was away.

It looks as if the college is very small.

Hop it. (Go away)

专四语法重点总结 It 句型(下)

Anticipatory it

it用来充当形式主语或形式宾语,后面的真正主语或真正宾语通常是不定式结构、动名词或名词性分句。It的这种用法叫作先行it。

eg.

It is quite important for us to form a good studying habit.

I think it important to finish the task in time.

it用来充当形式主语,后置的真正主语往往可以取代先行it的位置,出现在句首。

Eg. To form a good studying habit is quite important for us

并非所有先行it结构都可转化,下边句子只能作如下转化。

eg.

It seems that John is not coming after all.

John doesn?t seem to be coming after all.

Cleft it :

Task

1. 句子的基本结构

2 .分裂句的本质

3 . 分裂句的结构

4 .假拟分裂句

句子结构

主语+谓语

已知信息

新信息

末端中心

末端重心

Eg. I told him the news yesterday.

分裂句的本质

Eg. I told him the news yesterday.

Eg. It is I that told him the news yesterday

分裂it

分裂句是以it为引导词的强调句型。它的结构形式是:It +be 的一定形式+中心成分+that /who分句。通过这种结构可以强调除谓语动词以外的大多数句子成分。说话人通过分裂句分别强调主语、间接宾语、直接宾语、状语,使之成为信息中心。分裂句中的谓语可以采取复杂形式

Eg.

It is I who am to blame.

It may have been at Christmas that John gave Mary a handbag.

It was in Shanghai that I got my Master?s Degree.

主语补语通常不作分裂句的中心成分。宾语补语可以这样用。

*It is beautiful that she is.

It is Chairman of the committee that they elected him.

倒装

固定语序

主语+谓语

后置

1.句尾焦点和句尾重心

2.关键词语的后置

前置与倒装

1)不引起倒装的前置

不引起倒装的前置成分通常是宾语、主语补语和宾语补语。

2) 引起倒装的前置:

主语补语前置时,如主语较长或结构较复杂,就会引起倒装。

前置宾语由not a + 名词或 not a single + 名词,就会引起倒装

A horrible mess I have made of it.

Books, I need.

Happy indeed I am

Happy indeed are those who got the tickets to Beijing.

倒装

某些状语的前置会引起倒装: 全部倒装和部分倒装

a. 句首状语为方位词或拟声词,谓语动词为go, come等表示位置转移的动态动词时,通常用全部倒装,主语为代词,不用倒装。

Eg. Lower and lower he bent.

b. 当句首状语为表地点的介词词组时,也会引起全部倒装。

Eg. From the wall comes the voice of the doctor.

c. 当句首状语为否定词或带有否定意义的词语时,一般引起局部倒装。

Eg. Nowhere else could you find so cheap books.

d. 当句首状语为only + 副词, only +介词词组, only + 状语分句构成,也可引起局部倒装。 Eg. Only through sheer luck did he manage to get some tickets.

e. 以关联连词so (…that)开头的句子,引起局部倒装。so+形容词是主语补语的前置;so+副词是状语的前置。

Eg. So small was the mark that I could hardly see it.

f. 当方式状语、频度状语等移至句首时,有时也引起局部倒装。也可不用倒装。 Eg.

Many a time has Mike given me good advice.

Slowly and impressively he rose from his seat.
