C. 英语的常用语法

常用语法有 一、句型1——主语+谓语

我们知道，一个句子是为了说明一件事（或表达一种感情），最简单的表达方式，就是“谁，怎么样了”。这里的“谁”，就是句子的主语，它的内涵很丰富，可以是人、物、某种行为等。“怎么样了”，就是句子的谓语，由动词充当。主语+谓语，即构成一个最简单的句子。举一些简单的例子：

I dance.

She died.

we agree.

……

二、句型2——主语+谓语+宾语

句型2在句型1的基础上多了一个宾语，宾语是什么呢？还是从句子表达事情的角度看，可以理解为“谁，对谁怎么样了”。宾语，就是主语借助一个动作（谓语）作用的一个对象。还是举一些简单的例子：

I hate him.

I love you.

I dance with her.（注意，为什么这里多了一个with，学过动词那一节的同学肯定知道哦~）

……

三、句型3——主语+谓语+间接宾语+直接宾语

在这个句型里，我们发现谓语后面跟了两个宾语，直接宾语，就是谓语动词直接作用的对象，而间接宾语，是指谓语需要先借助于一个间接的对象，再把动作传递到直接宾语身上。

如，I give him a book.（“给”，这个动作，最终作用的对象是“书”，但需要先通过“他”，把“给”这个动作传递到书）

注意，如果理解不了这种句型，关系并不大，只有很少一些动词需要通过接两个宾语的方式来表达完整的意思，记住这些动词就行了。

四、句型4——主语+谓语+宾语+宾语补足语

相对于句型2，这种句型中又多了一个宾语补足语，“补足”意思就是补充说明，所以宾语补足语的作用，就是用来补充说明宾语怎么样了。

I want you to go with me.（我要你，要你干什么呢？to go with me，即要你跟我一些走，这个部分就是宾语补足语。）

注意，在这种句型中，补足语可能不是一个具体的单词。

五、句型5——主语+系动词+表语

还记得系动词吗？我们在动词那一节也讲过哦，这里就不复习了。这个句型，就是在讲如何使用系动词。表语，就是跟在系动词后面的成分的一个统称，不用过分在意它是什么意思。感官类系动词，其后一般接形容词；be动词后一般接名词（或不定式等）。同样举一些最简单的例子：

It smells good.

She is a teacher.

……

D. 英语的所有语法

英语语法是针对英语语言进行研究后，系统地总结归纳出来的一系列语言规则。语法是组词造句的规则，是把合适的词放进合适位置的艺术文化底蕴，语法可以分成为两大部分：分别为词法和句法。词法包括各类词的形态及其变化，句法主要讲句子的种类和类型，句子成分以及遣词造句的规律。语法的精髓在于掌握语言的使用。

(7)各类语法的英语扩展阅读

句型结构

句子按其结构可分为简单句、并列句和复合句。

1、简单句

基本形式：简单句的基本形式是由一个主语加一个谓语构成。其它各种句子形式都是由此句型发展而来，如五大基本句型：

（1）主语+谓语（s.+predicate）

这种句型简称为主谓结构，其谓语一般都是不及物动词，例：Things change.事物是变化的。Nobody went.没有人去。

（2）主语+系动词+表语（s.+link v.+predicative）

这种句型称为主系表结构，其实联系动词在形式上也是一种谓语动词，系动词与表语一起构成了复合谓语，例：Mr. Turner is an artist.特纳先生是位画家。

（3）主语+谓语+宾语（s.+predicate+o.）

这种句型可称为主谓宾结构，它的谓语一般多是及物动词，例：We never beat children.我们从来不打孩子。

（4）主语+谓语+间接宾语+直接宾语（s.+predicate+oi.+od.）

这种句型可称为主谓宾宾结构，其谓语应是可有双宾语的及物动词，两个宾语一个是间接宾语，一个是直接宾语，例：He gave the book to his sister.他把这本书给了他的妹妹。

（5）主语+谓语+宾语+宾语补足语（s.+predicate+o.+o.c.）

这种句型可简称为主谓宾补结构，其补语是宾语补语，与宾语一起即构成复合宾语，例：I found the book easy.我发现这本书不难。（形容词easy作补语）

注意：有时两个或更多的并列主语拥有一个共同的谓语，甚至并列有两个主语和两个谓语，这样的句子仍然是简单句，例：China and other countries in the east Asia are developing rapidly.

中国和东亚其它国家正在迅速地发展。（China and other countries并列主语）

2、It引导结构

It 既是代词又是引词。作代词时，它可做人称代词、指示代词、非人称代词，用于前指、非确指或习语中。作引词时，它本身无实义，只起先行引导的作用。

可作形式主语（it is + adj. + for/of sb. to do sth.）或形式宾语（it + adj. + to do sth.），真实的主语或宾语是不定式、动名词或名词从句，它们则放在后面。

It 也用于强调句结构。如想强调某个词或部分，可用it is (was) + 强调部分（主语、宾语或状语） + that(who）…的强调结构。本章要求了解代词it 和引词it 的各种用法，重点掌握it 用于前指或后指；引导词it 用于强调结构。

3、并列句

两个或两个以上的简单句用并列连词连在一起构成的句子，叫做并列句，其基本结构是“简单句+并列连词+简单句”。

并列连词有：and, but, or, so等。并列句是由两个或两个以上的简单句连接而成。并列句中的各简单句意义同等重要，相互之间没有从属关系，是平行并列的关系。它们之间用连词连结。

4、复合句

复杂句（Complex Sentence）由一个主句（Principal Clause）和一个或一个以上的从句（Subordinate Clause）构成。

主句是全句的主体，通常可以独立存在；从句则是一个句子成分，不能独立存在。

从句不能单独成句，但它也有主语部分和谓语部分，就像一个句子一样。所不同在于，从句须由一个关联词（connective）引导。

I. 常用的英语语法有哪些呢

语从句(Subject
Clause)
定义: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.
第一部分：常规主语从句,即句子在复合句中充当一个主语
第二部分：为了防止句子头重脚轻,通常把形式主语it放在主语位置,真正主语搁置于句末
状语从句
（Adverbial
Clause）
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.
同位语部分是个句子,就是同位语从句,这种用法比较"固定",把关键的几个词背下来.
下面这个材料供参考.
一、在复合句中用作同位语的从句叫同位语从句.它一般跟在某些名词后面,用以说明该名词表示的具体内容.如：
I
heard
the
news
that
our
team
had
won．我听到了我们队获胜的消息.
I
had
no
idea
that
you
were
here．我不知道你在这里.
二、可以跟同位语从句的名词通常有news,idea,fact,promise,question,doubt,thought,hope,message,suggestion,words（消息）,possibility等.如：
I’ve
come
from
Mr
wang
with
a
message
that
he
won’t
be
able
to
see
you
this
afternoon．
我从王先生那里来,他让我告诉你他今天下午不能来看你了.
三、英语中引导同位语从句的词通有连词
that,whether,连接副词
how,when,where等.（注：if,which
不能引导同位语从句.）如：
l
have
no
idea
When
he
will
be
back．我不知道他什么时候回来.
He
must
answer
the
question
whether
he
agrees
to
it
or
not.
他必须回答他是否同意这样一个问题.
四、有时同位语从句可以不紧跟在说明的名词后面,而被别的词隔开.如：
Several
years
later,word
came
that
Napoleon
himself
was
coming
to
inspect
them．
几年以后,有消息传来说拿破仑要亲自视
察他们.
The
thought
came
to
him
that
maybe
the
enemy
had
fled
the
city．
他突然想起可能敌人已经逃出城了.
五、同位语从句与定语从句的区别.
1、同位语从句与前面的名词是同位关系,即说明它前面名词的内容；而定语从句与前面的名词是修饰与被修饰关系,即限定它前面的名词范围,或补充一些情况.如：
The
news
that
l
have
passed
the
exam
is
true．我通过了考试这一消息是真的.
（同位语从句,即从句所表达的意思就是前面名词的内容.）
The
news
that
he
told
me
just
now
is
true．他刚才告诉我的消息是真的.
（定语从句,从句对前面名词起修饰限制作用,即“他告诉我的”那个消息,而不是别的消息.）
2、引导同位语从句的that是连词,在从句中不充当任何成份,而引导定语从句的that是关系代词,除起连接作用外,还在从句中充当主语、宾语或表语等.如：
The
idea
that
computers
can
recognize
human
voices
surprises
many
people.
计算机能够识别人的声音的想法使许多人感到惊奇.（that在从句中不充当任何成份.）
The
idea
that
he
gave
surprises
many
people．他提出的观点令许多人感到吃惊.
（that在从句中作gave的宾语.）
一个名词(或其它形式)对另一个名词或代词进行修饰,限定或说明,这个名词(或其它形
式)就是同位语.同位语与被它限定的词的格要一致,并常常紧挨在一起.
