###英语语法基础知识入门教程

音 标

学习提示：

在我们开始学习英语语音音标之前，有一点大家要记住：不要试图用汉语普通话的近似的音去代替英语的音标。例如，有人把英语字母“n’'念成“恩”，用汉语的“e”来代替英语的[e]，把字母f、m、x分别念成“爱弗”、“爱木”、“爱克斯”。这是一种很坏的习惯，它使你永远也学不到纯正的英语发音。记住，英语的音标跟汉语的音标缺乏可比性。例如，英语的单元音有十二个之多，而汉语只有六个。即使是两者相似的音，它们在发音的口型、音的长短上都有差别。

音素分类：

英语的音标共有48个，其中元音音标20个，辅音音标28个。相信大家对它们都不陌生了，在正式开始音标学习之前，让我们再来熟悉一下这48个音标。

元音

1、单元音 前元音：[i] [i:] [e] [?]

中元音：[?:] [?] [?]

后元音：[a:] [?] [?:] [u] [u:]

2、双元音 合口双元音：[ei] [ai] [?i] [?u] [au]

集中双元音：[i?] [ε? ] [u?]

辅音

1、爆破音 [p] [b] [t] [d] [k] [g]

2、摩擦音 [f] [v] [θ] [e] [s] [z] [?] [?] [h] [r]

3、破擦音 [ts] [dz] [tr] [dr] [t?] [d?]

4、鼻音 [m] [n] [?]

5、半元音 [j] [w]

6、舌侧音 [l]

音标记忆法：

不要为音标的分类名称操心，你并不需要记住这些名称;也不要为音标的数目太多而发愁，照下面的两个记忆方法去做，你一定能在十分钟内将所有的英语音标记住。

一、元音分组记忆法：将元音音标分成四个大组和四个单个，帮助记忆。

1、四大组

第一组 第二组 第三组 第四组

[i] [i:] [i?] [ei] [ai]

[?] [?:] [?u] [ε?]

[u] [u:] [u?] [au]

[?] [?:] [?i]

记忆窍门：

第一组为“基本型”;第二组为基本型的“延长型”;在基本型后加长音符号;第三组为基本型的“前置型”;第四组为基本型的“后置型”。

2.四单个：一座山[?]，一朵花[?]，一个[e]，一个[a:]

二、辅音成对记忆法：将辅音分成十对和八个单个，帮助记忆。

1.十对

爆破组 摩擦组 破擦组

[p] [b] [f] [v] [ts] [dz]

[t] [d] [θ] [e] [tr] [dr]

[k] [g] [s] [z] [t?] [d?]

[?] [?]

记忆口诀： 十对的辅音清、浊成对，每对的发音部位相同。

2.八单个：[m] [n] [?] [j] [w] [r] [l] [h]

记忆口诀：三鼻音[m] [n] [n], 两半元[w] [j] , 一个[r]，一个[l]，还有一个[h]。

音节

一、定义：一个元音音素(双元音为一个音素)为一个音节。

1、[ai] [n?u] [st?nd] [ti:t?] 均为单音节。

2、['mi:t?] ['reiz?] 均为双音节。

3、['s?u??list] [repri'zent?tiv]均为多音节。

二、音节的划分：

1、每两个元音之间有一个辅音，该辅音归后。如：['mi:t?] ['reiz?]

2、每两个元音之间有两个辅音，则前后各一个。如：['men??nd] ['f?ktri]

3、每两个元音之间有三个及以上的辅音，依次读出其本身的发音即可。如：

['empti]

简记为：一归后，二分手。

试读：[steid] ['a:ft?] ['men??nd] ['f?ktri] ['s?u??list] [repri'zent?tiv]

三、开、闭、r音节：

1、开音节，又分绝对开音节和相对开音节。

绝对开音节：以发音的元音字母结尾的音节。如：no，we.she。

相对开音节：以元音字母+辅音字母(r除外)+不发音的e结尾的音节。如：these，those，page，life，use。

2、闭音节：以一个或几个辅音字母(r除外)结尾，而中间只有一个元音字母的音节。如：bad，desk，sit，long。

3、，元音字母+r，即 ar er ir or ur

4、元音字母在重读开音节、重读闭音节和r读音节中的读音。

元音字母在重读音节中的读音

字母 开音节 例词 闭音节 例词 r音节 例词

A [ei] name [?] bag [a:] car

E [i:] these [e] pen [?:] her

I [ai] bike [i] his [?:] girl

O [?u] no, note [?] not [?:] for

U [ju:] student [?] bus [?:] nurse

由上表可见：元音字母在重读的开音节中就读字母本身的音。(注意：一切规律都不能包罗万象，如，不符合此规律的词有come, love 等等)

句子成分与句子

第一章 句子成分

构成句子的各个部分叫做句子成分。英语句子主要成分有主语、谓语、表语、宾语、状语、补足语和定语。

1、主语

主语是一个句子的主体，是句子所要说明的人或事情，表示句子描述的是“谁”“什么”。主语一般位于陈述句句首，但在there be结构中主语位于谓语后面。

能作主语的有名词类(含代词、数词);非谓语(含不定式、ing 分词)、从句。

1)名词类

Professor Smith is a famous scientist.史密斯教授是著名的科学家。

We often speak English in class.我们经常在课堂上说英语。

One-third of the students in this class are girls.这个班1/3的学生是女生。

第二章 句子

第一节 简单句

简单句的五种基本句型

英语句子的主要特征是：是句子就必须含有主、谓。英语简单句有以下五种基本句型。

1.主语+系动词+表语(简称，主系表)

系动词+表语构成名词性合成谓语;可作表语的有名词、名词所有格、代词主格或宾格、名词性物主代词、指示代词、不定代词、形容词、副词、数词、介词短语、现在分词、过去分词、动名词、动词不定式和从句等。

He seems a clever boy.他似乎是个聪明的男孩。

She looks like her mother.(介词短语)她样子象她母亲。

4.主语+及物动词+间接宾语+直接宾语(简称，主谓双宾)

直接宾语和间接宾语又叫双宾语。直接宾语指物，间接宾语指人。二者没有逻辑的主谓关系。要求跟双宾语的动词可分为两类：

(1)give，show，send，pass，hand，lend，post，serve，read，take，write，tell，teach.return，wish，allow，offer，promise，throw等。(sth. to sb.)

I lent her a novel.= I lent a novel to her. 我借给她一本小说。

Please do me a favor.= Please do a favor for me. 请帮个忙。

5.主语+及物动词+宾语+宾补(简称，主谓复合宾)

有些动词带一个宾语意思不完整，还需要一个宾语补足语进一步说明，意思才完整。宾语+宾语补足语构成复合宾语。宾语和宾语补足语之间有逻辑的主谓关系。双宾语之间则没有逻辑的主谓关系。

可作宾语补足语的词类有：名词、形容词、副词、不定式、现在分词、过去分词和介词短语。

常见的要求带宾补的动词有：make，elect，choose，call，name，leave，find, keep, think, set, let，see，show，ask，tell，invite，want，wish，advise，get，force，oblige，allow，permit，like，encourage，order，expect，prefer，hate，persuade等。

第四节 名词性从句

一、 定义

首先，请同学们说出下列句各中划线词的词性及语法作用。

Mary is a teacher.

I like English.

结论：它们都是名词，在句中分别做主语、表语和宾语。即在英语中名词的主要作用是做主语、表语和宾语。

然后，我们一起分析下列各句中划线部分的语法作用。

That Mary is a teacher is known to us all.

I know that Mary is a teacher.

The fact is that Mary is a teacher.

结论：它们分别做主语、宾语和表语。均起到了一个名词的作用。再者，划线部分本身就是一个句子，故在复合句中起名词作用的从句统称名词性从句。

二、分类

请重读上述例句并依据它们在全句中的作用，说出它们具体的从句名称。

That Mary is a teacher is known to us all.

I know that Mary is a teacher.

The fact is that Mary is a teacher.

结论：在复合句中起主语作用的从句称为主语从句;

起____作用的从句称为宾语从句;

起表语作用的从句称为____从句;

名词性从句分三类：主语从句;宾语从句和表语从句。

三、连词

引导名词性从句的引导词有三类：

1. that

2. whether/if(主要用于引导主语从句和宾语从句);as if(主要用于引导表语从句)

3. who, whom, whose, what, which, when, where, why, how.

主语从句

that引导的主语从句

That he will come tomorrow is certain.

That she became monitor made us happy.

英文中有一种习惯，把that 引导的主语从句用it来代替它，即it做形式主语，把做真正主语的主语从句放在主句之后。如：

That he will come tomorrow is certain.

=It is certain that he will come tomorrow. 再例：

It is necessary that we learn English well.

It is a pity that we can’t go shopping.

It is said that he has been to England.

whether引导的主语从句

Whether she will be our teacher is not clear.

=It is not clear whether she will be our teacher.

Whether he will succeed or not doesn’t interest me.

=It doesn’t interest me whether he will succeed or not.

wh-词和how 引导的主语从句

(who, whom, whose, what, which, when, where, why均以wh开头，故统称wh-词)

Who will be our English teacher has not been decided.

What you have said sounds reasonable.

注意：1. that在主语从句中不起任何语法作用，但不能省略。

2. if 不能引导主语从句。

宾语从句

它可以作动词谓语的宾语，也可作非谓语动词、某些介词和某些形容词的宾语。

that引导的宾语从句

I really believe(that)Tom was telling the truth.

I am sure that we can get there on time.

由that引起的宾语从句在意思上相当于陈述句，此时that常可省去，但在以下几种情况下，that不可省。

1)that从句被短语，词组等与谓语动词分隔开时，that不可省。

They told us once again that this should never happen.

(此句中that引导的宾语从句被词组once again与主句隔开，因此that不可省。)

Everyone could see，I believe, that Mike was terrified.

(句中I believe为插入语，故that不可省)

2)当连接两个或两个以上的宾语从句时，第二个从句及以后的连接词that不可省。

She said(that)her mother had gone abroad and that she would come back in a week.

whether，if 引导的宾语从句

I don，t know if/whether he has ever been to New York.

I wonder whether he can speak German or not.

以上例句中的whether和if(是否)都是引导宾语从句的，一般情况下whether，和if可互换。但在下列情况下whether和if不可换用。

1)whether之后可紧跟or not或构成whether.. .or not结构，if后一般不能紧跟or not,但可构成if...or not结构.
