英语中各种词性的用法及区别~

英语词类分十种:
名词、形容词、代词、数词、冠词、动词、副词、介词、连词、感叹词。
1、名词(n.): 表示人、事物、地点或抽象概念的名称。如:boy, morning, bag, ball, class,
2、代词(pron.): 主要用来代替名词。如:who, she, you, it .
3、形容词(adj..):表示人或事物的性质或特征。如:good, right, white, orange .
4、数词(num.): 表示数目或事物的顺序。如:one, two, three, first, second, third, fourth.
5、动词(v.): 表示动作或状态。如:am, is,are,have,see .
6、副词(adv.): 修饰动词、形容词或其他副词,说明时间、地点、程度等。如:now, very, here, often, quietly, slowly.
7、冠词(art..):用在名词前,帮助说明名词。如:a, an, the.
8、介词(prep.): 表示它后面的名词或代词与其他句子成分的关系。如in, on, from, above, behind.
9、连词(conj.): 用来连接词、短语或句子。如and, but, before .
10、感叹词(interj..)表示喜、怒、哀、乐等感情。如:oh, well, hi, hello.

1.名词

名词可以分为专有名词(Proper Nouns)和普通名词 (Common Nouns),专有名词是某个(些)人,地方,机构等专有的名称,如Beijing,China等。普通名词是一类人或东西或是一个抽象概念的名词,如:book,sadness等。普通名词又可分为下面四类:
1)个体名词(Individual Nouns):表示某类人或东西中的个体,如:gun。
2)集体名词(Collective Nouns):表示若干个个体组成的集合体,如:family。
3)物质名词(Material Nouns):表示无法分为个体的实物,如:air。
4)抽象名词(Abstract Nouns):表示动作、状态、品质、感情等抽象概念,如:work。


2. 形容词

形容词修饰名词,说明事物或人的性质或特征。通常, 可将形容词分成性质形容词和叙述形容词两类,其位置不一定都放在名词前面。

1) 直接说明事物的性质或特征的形容词是性质形容词,它有级的变化,可以用程度副词修饰,在句中可作定语、表语和补语。例如:hot 热的。

2) 叙述形容词只能作表语,所以又称为表语形容词。这类形容词没有级的变化,也不可用程度副词修饰。大多数以a开头的形容词都属于这一类。例如:afraid 害怕的。
(错) He is an ill man.
(对) The man is ill.
(错) She is an afraid girl.
(对) The girl is afraid.
这类词还有: well,unwell,ill,faint,afraid,alike,alive,alone,asleep,awake 等。

3)形容词作定语修饰名词时,要放在名词的前边。但是如果形容词修饰以-thing为字尾的词语时,要放在这些词之后,例如:
something nice


3.副词及其基本用法

副词主要用来修饰动词,形容词,副词或其他结构。
一、副词的位置:
1) 在动词之前。
2) 在be动词、助动词之后。
3) 多个助动词时,副词一般放在第一个助动词后。

注意:
a. 大多数方式副词位于句尾,但宾语过长,副词可以提前,以使句子平衡。
We could see very clearly a strange light ahead of us.
b. 方式副词well,badly糟、坏,hard等只放在句尾。
He speaks English well.

二、副词的排列顺序:
1) 时间,地点副词,小单位的在前,大单位在后。
2) 方式副词,短的在前,长的在后,并用and或but等连词连接。
Please write slowly and carefully.
3) 多个不同副词排列:程度+地点+方式+时间副词。

注意:副词very 可以修饰形容词,但不能修饰动词。
改错:(错) I very like English.
(对) I like English very much.

注意:副词enough要放在形容词的后面,形容词enough放在名词前后都可。
I don't know him well enough.
There is enough food for everyone to eat.
There is food enough for everyone to eat.


……
形容词/定冠词/不定冠词都是用来修饰名词的
adj可修饰的是可数名词复数或者是单数 定冠词可修饰不可数和可数名词
不定冠词a/an修饰可数名词单数
副词(adv)修饰动词或者是动词短语
be动词后跟形容词或者是现在分词
介词(prep)后面跟动名词
一般用于句首常见的有be动词,特殊疑问词(how what where ……)等,另如祈使句,通常是Don’t…
情态动词(aux)后跟动词原形
联系动词(Lv.)后跟形容词原级

介词是一种用来表示词与词, 词与句之间的关系的词。在句中不能单独作句字成分。
介词后面一般有名词代词或相当于名词的其他词类,短语或从句作它的宾语。介词和
它的宾语构成介词词组,在句中作主语, 状语,表语,补语或介词宾语。例如:

Most of the students went to the classroom.
大部分学生去了教室。

We play basketball on the sports ground.
我们在操场上打蓝球。

介词常与动词,形容词,名词一起构成固定搭配。

belong to 属于 rely on 依靠
talk to 同...谈话 be afraid of 害怕
be strict with对...严格

介词一般放在名词之前。但它后面的介词宾语是疑问代词,疑问副词或者关系代词时,
这些词提到了前面而只剩下介词在后了。

Where do you come from?
你是哪儿人?
Who are you talking to?
你在跟谁谈话呢?
What do you study for?
你为了什么而学习?

介词在英语词汇中所占比例很小,但它们的用法却非常灵活,复杂。以下是一个例子:

about 关于,附近,大约,周围,随身.

I have bought a book about Shakespearean.
我买了一本有关莎士比亚的书。

英文中数字的写法和汉语有所不同,想必大家都已经了解。但日常生活中难免还会连词是指把词、词组、分句和句子甚至段落连接起来的起连接作用的词或词组。连词的种类很多,主要有以下几类:

一、并列连词

1、表示对等关系的并列连词。使用该类并列连词时必须保持结构对等,词性统一,在句子中要使用对等成分,不可失之偏颇。常用的该类连词有:and,either...or,neither...nor,as well as,both...and,not only...but also。如:

This is an old clock that is not only very handsome but also accurate.

2、表示选择关系的并列连词。常用的该类连词有:or,or else,otherwise,rather than,either...or。如:

You should get the license right away,or you'll have to pay a fine.

3、表示转折和对比关系的并列连词。常用的该类连词有:but,while,whereas,yet,however,nevertheless,on the other hand,on the contrary。如:

She is a funny girl,yet you can't help liking her.

4、表示因果关系的并列连词。常用的该类连词有:so,for,therefore,hence,thus,consequently,accordingly。如:

It was raining heavily,so the sports meeting was postponed.

二、从属连词

1、引导时间状语的从属连词。该类连词除一些常用的外,还包括:as soon as,the moment(一……就……),the minute,the instant,once, immediately(一……就……),no sooner...than

(一……就……),hardly...when(刚……就……)。

如:

He told me the news immediately he got it.

2、引导地点状语的从属连词。该类连词有两个:where和wherever。如:

Where there is a life,there is a hope.

3、引导条件状语的从属连词。该类连词除

if,unless和if only(要是……就好了),还有:

provided(that),providing(that),supposing(that),

suppose,in case(that),as long as(只要),on condition that。如:

If only I had more money,I could buy some new clothes.

4、引导目的状语的从属连词。该类连词主要有:so that,that,in order that,lest,for fear that, in case(that)。例如:

She worried for fear that the child would be hurt.

5、引导原因状语的从属连词。该类连词主要有:as,because,since,in that, now that(既然),seeing that(鉴于)。例如:

Seeing that it is eight o'clock,we'll wait no longer.

6、引导比较状语的从属连词。该类连词主要有:as,as...as,less(more)... than,the more...the more。例如:

The more we can do for you,the happier we will be.

7、引导方式状语的从属连词。该类连词主要有:as,as if(好像),as though(好像)。例如:

Heat can flow from a hot body to a cooler body as if it were a fluid.

8、引导结果状语的从属连词。该类连词主要有:so...that,such...that,so(that)。例如:

He is such an honest man that everyone would like to trust him.

9、引导让步状语的从属连词。该类连词主要有:though,although,even if,even though, while,as,whatever,however,whoever,no matter...(不管)。例如:

Hard as he tried,he failed to pass the exam.

三、连接代词和连接副词

这类词用来引导名词性从句。连接代词有:that(不充当成分),which,what,who,whose等;连接副词有:when,where,how,why等。

四、关系代词和关系副词

这类词用来引导定语从句。关系代词包括:who,that,which,as,whose,whom等。关系副词包括:when,where,why,how等。关系代词和关系副词起着三重作用:其一,它们连接着主句和从句;其二,它们代表着主句的一个先行词(which和as还可以代表主句中的一个词组或整个句子);其三,它们又在从句中充当成分。
