初中英语知识归纳总结(打印版)
第一课时 名 词
一、概述
1、名词的属性:表示人或事物的名称抽象概念的词叫名词。
2、名词分普通名词和专有名词。普通名词是表示某一类人或事物,或某种物体或抽象概念的名称。如:teacher, desks, plates, milk, box等,专有名词表示某一特定的人、事物、地方团体、党派、国家机关、语言、节日等专用的名称。(运用)如:China, Chinese, Saturday, June, Green, Beijing, Olympic等。(专有名词的第一个字母要大写)
二、可数名词与不可数名词
1、可数名词是指表示人或事物,可以用数来计量的名词,有单复数之分。如:glass-----glasses; book---- books
2、不可数名词是指所表示的事物不能用数来计量。
如:paper, rice, water , milk, tea等。
3、有些名词在特定情况下由不可数变为可数名词。
Light travels faster than sound; (light:光线,不可数)
The lights are on. (light:灯,可数)
4、不可数名词的量的表示
不可数名词一般无法用数来计算,前面不能用a或an或数词来表示数量,它的量往往借助于容器来表示。
如:a glass of milk ------ four glasses of milk
a piece of paper ------ two pieces of paper
a bag of rice ------ three bags of rice
三、可数名词的复数形式(识记、运用)
1、可数名词在应用时有单复数之分,单数变复数有规则变化和不规则变化两种。

四、名词所有格(运用)
名词的所有格是表示所有关系的形式,它也有构成上的变化。
1、单数名词变所有格,只需在词尾加 ’ s;
2、复数名词的词尾已有s,只需加 ’ 即可;
3、复数名词的词尾若没有 s ,则应加’ s ;
4、如果表示某人或物为两人所共有,则在第二个人后面加’ s ;
如:Da Mao and Xiao Mao’s room
如果不是两人共有,则在每个人后面都加 ’ s;
如:Li Lei’s and Tom’s mother
5、名词所有格结构通常用于表示有生命的名词,或表示时间、距离、地点等,而表示无生命名词的所有关系则用“of”表示。
如: the windows of house the picture of the family
of 结构也能用于有生命名词的所有格。

第二课时 冠 词(一)
一、概述
冠词是一种虚词,在句子中不重读,本身不能独立使用。在汉语中没有这个词类。在学习冠词时,要注意这种加在名词前帮助说明名词所指的人或事物的词表示数量“一”时,与数词的区别;其表示“数量”的意义没有“one”强,这是学习中注意区别的。
二、冠词的定义
冠词是置于名词之前,说明名词所表示的人或事物的一种虚词,它不能离开名词而单独存在。冠词有两种:
一种是定冠词(the Definite Article);the
一种是不定冠词(the Indefinite Article). a an
三、不定冠词的用法
a用于辅音音素起首的单词前,an用于元音音素起首的单词前。
1、当第一次提到某人或某物时,用a或an起介绍作用,如:

at a time have a try take a chance
5、表示“每一个”的意思。如:
three times a day four yuan a dozen
6、可用于抽象名词之前,使抽象名词具体化。如:
I am quite at a loss;
The little child is a joy to his parents.
7、用于物质名词之前,使物质名词普通化。如:
He drew out a tin of pineapple.
They made a fire to get warm.
注意:
1、不定冠词an用在以元音(不是字母,而是发音)起首的名词或其他以元音起首的词之前,不定冠词a用在以辅音起首的名词或其他以辅音起首的词之前。
2、u和h有时在单词中发元音,有时却读作辅音或不发音。如:
I have been waiting for an hour.
He is an honest young fellow.
A hammer is a useful fool.
3、英语中有些字母,如f h l m n s x。由于它前头第一个音是元音,所以在单独使用或作缩略词的第一个字母时,应使用“an”,如:
There is an “n” in the word “no”.
An MP means a member of parliament.
