语法

一、句子的5类成分
句子成分可以分为基本成分、附属成分、独立成分、省略成分和连接成分5类。

1．基本成分
根据其结构，句子可以分为5类：
a．主语＋不及物动词
John came．
（S）（IV）
b．主语＋及物动词＋宾语
John likes oranges．
（S）（TV）（O）
c．主语＋双宾动词＋间接宾语＋直接宾语
John gave Mary books．
（S）（DV）（IO）（DO）
d．主语＋系动词＋主语补语
John is happy．
（S）（LV）（SC）
e．主语＋宾补动词＋宾语＋宾语补语
John makes Mary angr y．
（S）（FV）（O）（OC）
主语、不及物动词、及物动词、双宾动词、系动词、宾补动词、宾语及补语可以称为基本句子成分。

在上面的句子中，如把任何一个成分删除，都会成为病句。

从上面例句也可看出，完整的句子一般至少包含2个基本成分，至多4个基本成分
2．附属成分
1303基本成分可以加修饰语：1）定语（即用来修饰名词的单词、短语或从句）或2）状语（即用来修饰名词或代词以外的词的单词、短语或从句）。

下面例句中，修饰语为斜体字，被修饰的词为黑体字：
1）Poor John tottered toward a hospital nearby．
John likes oranges imported from the U．S．．
John gave Mary many books，which are full of illustrations．
2）John often came to chat with me．
John likes oranges very much．
Whenever he gets drunk，John makes Mary very angry．
这类句子，即使把修饰语去掉，结构仍是完整的。

这种修饰语，可能在意思上很重要，但在结构上不影响句子的完整性，因此称作附属成分。

3．独立成分
1304句中还有一类成分，可以去掉，不影响句子的完整性，并和句子的其他词没有语法的关系，可以称作独立成分。

Oh！What is that！（惊叹词）
He has，alas，failed again．
Come here，John．（呼语）
Roll on，Ocean，roll on．
4．省略成分
1305此外还有一类被省略的成分，虽然未说出来，却在句中表示一定的意思：
（You） Come here．
（I wish you）Good luck！
Some gave him praises，but others（gave him）rotten eggs．
5．连接成分
1306最后还有连接成分，它实际上是一个并列连词，用来连接两个或几个平行的词、短语和分句。

1307 ，一个完整的句子（从句或分句）必须包含2个到4个基本成分，此外，如果意思上有需要，还可包含一个或更多其他的句子成分。

Ⅱ．名子中词语特点的3种表达方式
1308句中词的特点可以3种方式来加以说明：
1．解析
2．分析
3．图解
以That boy shook his head．为例，可以下面 3种方式加以说明：
1．解析
That—指示形容词，修饰单数名词boy。

boy—普通名词，阳性，单数，主格，为动词shook的主语。

shook—及物动词，过去式。

his—物主代词，阳性，单数，第三人称，所有格，修饰名词head。

head—普通名词，中性，单数，宾格，shook的宾语。

2．分析
3．图解
{ewc MVIMAGE,MVIMAGE, !4F6004T1.bmp}
解析对词的分类处理过多，不甚有用。

分析说明了句中词之间的关系，但有时显得很复杂。

图解最有用，因为它以最简单明了的方式说明了词与词之间的关系，这种关系有时会把读者弄糊涂。

Ⅲ．图解规则
1．4个基本成分的图解办法
1309 5类基本句及4种基本成分可以用下面的方式加以图解：
{ewc MVIMAGE,MVIMAGE, !4F6004T2.bmp}
{ewc MVIMAGE,MVIMAGE, !4F6005T1.bmp}
一个词的特定地位意味着它的特定作用。

和横线交叉的左边竖线把主语S （在左面）和动词V（在右面）分开。

斜线表示它右面的词为主语或宾语的补语。

另一竖线表示右面的词为宾语O。

2．附属成分的图解办法
1310主语、动词。

宾语及补语这4种基本成分都放在横线的上方，附属成分，如形容词、副词及起相同作用的其他词语，都放在横线的下方，紧挨在它们所修饰词的下面：
My father left yesterday．
{ewc MVIMAGE,MVIMAGE, !4F6005T2.bmp}
Some people write commercial letters skillfully．
{ewc MVIMAGE,MVIMAGE, !4F6005T3.bmp}
Some naughty little children broke his expensive spectacles purposely．
{ewc MVIMAGE,MVIMAGE, !4F6005T4.bmp}
A downright bad man is very often a wonderfully successful man．
{ewc MVIMAGE,MVIMAGE, !4F6006T1.bmp}
The old man opposite the street visited his children in Francein 1968．{ewc MVIMAGE,MVIMAGE, !4F6006T2.bmp}
3．成语、助动词、动名词等的图解办法
1311应当记住，一个空位通常只容一个词（类），但成语由几个词构成却起一个词（类）的作用。

因此有必要把构成成语的几个词放在一个空位中，因为成语表示一个单一的意思，不宜分割成几个词（类）：
The Minister of Economics paid attention to the inflation．
{ewc MVIMAGE,MVIMAGE, !4F6006T3.bmp}
助动词应和主要动词放在一起：
She has been raising her children for the last ten years．
{ewc MVIMAGE,MVIMAGE, !4F6006T4.bmp}
介词短语、不定式短语、动名词短语或名词从句，在用作主语、宾语或补语时，可用一个来进行图解，不仅表示其内在结构，还表示它作为一个词和其他词的关系：
He is in a bad temper．
{ewc MVIMAGE,MVIMAGE, !4F6007T1.bmp}
注意，这个句子有3个基本成分：主语+系动词+补语。

第三部分in a bad temper的图解，不仅说明了这 4个词之间的关系，还通过使用说明它作为一
个单一词类和其他词之间的关系，即起形容词的作用，作为系动词is的补语。

在下面图解中，这个短语占了2个空位，这样容易引起误会，因为人们会以为这个句子包含4个基本成分：
{ewc MVIMAGE,MVIMAGE, !4F6007T2.bmp}
To tell lies is not always successful·
{ewc MVIMAGE,MVIMAGE, !4F6007T3.bmp}
上面图解中to tell lies这个不定式短语，一方面表明了to tell 是一个及物动词，lies是它的宾语，另一方面说明整个短语起名词作用，只占一个空，作为句子的主语。

如果用下面图解，就会引起误会：
{ewc MVIMAGE,MVIMAGE, !4F6008T1.bmp}
He likes playing tennis in the morning．
{ewc MVIMAGE,MVIMAGE, !4F6008T2.bmp}
注意上面动名词playing tennis in the morning的图解，一方面说明playing为及物动词，tennis为其宾语，而in the morning为其修饰语，另一方面说明这个短语起名词作用，用作及物动词（谓语动词）like的宾语。

He washes before taking dinner．
{ewc MVIMAGE,MVIMAGE, !4F6008T3.bmp}
注意，talking dinner这个动名词短语，通过使用，表明为一个单一词类，起名词作用，用作介词before的宾语。

如作下面图解则会引起误会：{ewc MVIMAGE,MVIMAGE, !4F6008T4.bmp}
know that you speak English well．
{ewc MVIMAGE,MVIMAGE, !4F6008T5.bmp}
注意that引起的从句的图解，一方面表明了这5个词之间的关系（that为连词，主语为you，speak为及物动词，宾语为english，well为speak的修饰语），另一方面说明整个从句起一个单一词即名词的作用，用作及物动词，know 的宾语。

that上下的两条模线表明它是一个连词。

4．其他规则
1312 在图解中省略的词应用圆括号标出：
He has walked fifty miles．
{ewc MVIMAGE,MVIMAGE, !4F6009T1.bmp}
Come here．
{ewc MVIMAGE,MVIMAGE, !4F6009T2.bmp}
What（=The thing which）I know is unimportant．
{ewc MVIMAGE,MVIMAGE, !4F6009T3.bmp}
问号及惊叹号放在正横线右边末尾，在图解中大写字母保持不变：
Can he come？
What a trip we have had！
{ewc MVIMAGE,MVIMAGE, !4F6009T4.bmp}
只要句子的意思保持不变，词语位置的任何变动都不影响图解。

He left for France yesterday．和Yesterday he left for France．图解的方式一样：
{ewc MVIMAGE,MVIMAGE, !4F6010T1.bmp}
同样，I sing this song specially for you．和Specially for you I sing this song．图解的方式一样：
{ewc MVIMAGE,MVIMAGE, !4F6010T2.bmp}
My happy days are gone！和 Gone are my happy days！也如此：
{ewc MVIMAGE,MVIMAGE, !4F6010T3.bmp}
某个特殊的句子，根据不同的理解可有不同的图解方式。

例如在 He is out of temper．中，out of temper可看作是成语，是一个整体，这时图解方式如下：
{ewc MVIMAGE,MVIMAGE, !4F6010T4.bmp}
如果把它看作介词短语，包含2个成分，则可作如下图解：
{ewc MVIMAGE,MVIMAGE, !4F6010T5.bmp}
在Walking along the street，John met Mary．这个句子中，Walking along the street可以看作定语，这时可以按下面方式图解：
{ewc MVIMAGE,MVIMAGE, !4F6011T1.bmp}
如果把它看作状语，图解会是下面这个方式：
{ewc MVIMAGE,MVIMAGE, !4F6011T2.bmp}
还有一些其他规则，说明如下：
在主要横线左端下方的竖线来表示它后面或下面的词和全句有关，可以是一个句子修饰语或是一个把这个句子和另一句子连接起来的并列连词：
Luckily，I found the lost ring．
{ewc MVIMAGE,MVIMAGE, !4F6011T3.bmp}
In at word，I can do no more．
{ewc MVIMAGE,MVIMAGE, !4F6011T4.bmp}
I study music and my wife does housework．
{ewc MVIMAGE,MVIMAGE, !4F6011T5.bmp}
He is a great politician；besides，he is an artist．
{ewc MVIMAGE,MVIMAGE, !4F6012T1.bmp}
He worked very hard；on the other hand，his children played all day．
{ewc MVIMAGE,MVIMAGE, !4F6012T2.bmp}
Indeed he knows his fault，but he refuses to own it．
{ewc MVIMAGE,MVIMAGE, !4F6012T3.bmp}
最后，注意以后各节中，凡有星号的例句，都将在各句型讲完之后加以图解。

第十七单元
主语的12种类型（附图解）
1313 名词或代词是主语最重要的形式，却不是唯一的形式。

除了名词和代词，还有10种其他东西可以用作主语。

由于它们都起名词的作用，可称作名词等同体（Noun-Equivalent）。

此外，下面可以看到，it是一个作主语的重要代词。

Ⅰ．名词（或代词）

There it stood a monument of all ages．
It is funny the way（that）he teaches his children．

It astonishes me the number of the wives he has．

My sister studied at A．A．A．School when she was seventeen．是原来的句子，对主语加以强调时可改为上面形式。

）
It is English（宾语受到强调）that（or which） my sister studied，etc．
It is at A．A．A．School（状语短语受到强调）that（or where）my sister studied English，etc．

可参阅1318—1322。

{ewc MVIMAGE,MVIMAGE, !4F6017T1.bmp}
{ewc MVIMAGE,MVIMAGE, !4F6018T1.bmp}
It表示 the thing，that引起的从句可以看做定语，修饰主语It。

that
起从属连词和代词的作用，图解记号异于并列连词。

Ⅳ．the+形容词（或分词）
1317 The brave deserve the fair．The young are to be educated．There are the dying and the dead，the slain and the van－ guished．（复数主语）
The beautiful and the good is our ideal．The middle or the thick of the forest has many animals in it．The accused（or The deceased）is a rich man．The French is different in character from the English．（单数主语）
{ewc MVIMAGE,MVIMAGE, !4F6018T2.bmp}

（这三句意思相同，可比较其主语。

）
To handle a wife who comes of a rich family seems difficult．It seems difficult to handle a wife who comes of a rich family．A wife who comes of a rich family，it seems difficult to handle．
不定式可以有一个意义上的主语：

For a commoner to marry a nobleman's daughter does not astonish me．It does not astonish me for a commoner to marry a nobleman's daughter．
For politicians to talk about peace is as funny as for drinkers to talk about temperance．It is as funny as for drinkers to talk about temperance，for politicians to talk about peace．

（动名词这里有意义上的主语）
{ewc MVIMAGE,MVIMAGE, !4F6022T1.bmp}
注意动名词意义上主语John's如何图解的。

Ⅶ．that引起的从句
1320 由 that引起的主语从句常可用 it代替，而本身则移到句尾，作为it的同位语：
That he had succeeded pleased me very much．It pleased me very much that he had succeeded．

）

It is said（or denied，rumoured）that the Mayor fell in love with Mary．The Mayor，it is said（or denied，rumoured），fell in love with Mary．（这两句意思几乎相同，但在第二句中不能用 that。

）
{ewc MVIMAGE,MVIMAGE, !4F6024T1.bmp}
由that引起的从句用作名词及主语。

注意连词that的图解方式。

{ewc MVIMAGE,MVIMAGE, !4F6024T2.bmp}
Ⅷ．疑问词引起的从句
1321 由疑问词引起的从句，和that引起的从句一样，可以由it代替：

{ewc MVIMAGE,MVIMAGE, !4F6025T1.bmp}

{ewc MVIMAGE,MVIMAGE, !4F6025T2.bmp}
Ⅸ．疑问词+不定式

{ewc MVIMAGE,MVIMAGE, !4F6026T2.bmp}。
