初中英语语法
一.名词名词单数变复数规则
【速记口诀】
单数变复数,规则要记住,
一般加s,特殊有几处:
/s/结尾,es不离后,
末尾字母o,大多加s,
两人有两菜,es不离口,
词尾f、fe,s前有v和e;
没有规则词,必须单独记。
【妙语诠释】①大部分单数可数名词变为复数要加s,但如果单词以/t?蘩/、/?蘩/、/s/发音结尾(也就是单词如果以ch,sh,s,x等结尾),则一般加es;②以o结尾的单词除了两人(negro,hero)两菜(tomato,potato)加es外,其余一般加s;③以f或fe结尾的单词一般是把f,fe变为ve再加s;
④英语中还有些单词没有规则,需要特殊记忆,如child—children,mouse—mice,deer—deer,sheep—sheep,Chinese—Chinese,ox—oxen,man—men,woman—women,foot—feet,tooth—teeth。
三、名词所有格用法
【速记口诀】
名词所有格,表物是“谁的”,
若为生命词,加“’s”即可行,
词尾有s,仅把逗号择;
并列名词后,各自和共有,
前者分别加,后者最后加;
若为无命词,of所有格,
前后须倒置,此是硬规则。
【妙语诠释】①有生命的名词所有格一般加s,但如果名词以s结尾,则只加“’”;②并列名词所有格表示各自所有时,分别加“’s”,如果是共有,则只在最后名词加“’s”;③如果是无生命的名词则用of表示所有格,这里需要注意它们的顺序及汉语不同,A of B要翻译为B的A。

名词的种类:
II. 名词的数:
1. 规则名词的复数形式:名词的复数形式,一般在单数形式后面加-s或-es。现将构成方法及读音规则列表如下:
名词在句中表示所有关系的语法形式叫做名词所有格。所有格分两种:一是名词词尾加’s 构成,二是由介词of加名词构成。前者多表示有生命的东西,后者多表示无生命的东西。
用于无生命的东西:the legs of the chair, the cover of the book
用于有生命的东西,尤其是有较长定语时:the classrooms of the first-year students
用于名词化的词:the struggle of the oppressed
二.冠词
冠词基本用法
【速记口诀】
名词是秃子,常要戴帽子,
可数名词单,须用a或an,
辅音前用a, an在元音前,
若为特指时,则须用定冠,
复数不可数,泛指the不见,
碰到代词时,冠词均不现。
【妙语诠释】冠词是中考必考的语法知识之一,也是中考考查的主要对象。以上口诀包括的意思有:①名词在一般情况下不单用,常常要和冠词连用;②表示不确指的可数名词单数前要用不定冠词a或an,确指时要用定冠词the;③如复数名词表示泛指,名词前有this,these,my,some等时就不用冠词。
4.冠词分为不定冠词(a, an),定冠词(the),和零冠词。

代词可以分为以下七大类:
1. one, some及any:

I have some questions to ask.
2) some可用于疑问句中,表示盼望得到肯定的答复,或者表示建议,请求等。

Could you give me some money?
3) some 和any修饰可数名词单数时,some表示某个,any表示任何一个。
I have read this article in some magazine.
Please correct the mistakes, if any.
4) some和数词连用表示“大约”,any可及比较级连用表示程度。
There are some 3,000 students in this school.
Do you feel any better today?
2. each和every:
each强调个别,代表的数可以是两个或两个以上,而every强调整体,所指的数必须是三个或三个以上。
Each student has a pocket dictionary. / Each (of us) has a dictionary. / We each have a dictionary. Every student has strong and weak points. / Every one of us has strong and weak points.
3. none和no:
no等于not any,作定语。none作主语或宾语,代替不可数名词,谓语用单数,代替可数名词,谓语单复数皆可以。
There is no water in the bottle.
How much water is there in the bottle? None.
None of the students are (is) afraid of difficulties.
4. other和another:
1) other泛指“另外的,别的”常及其他词连用,如:the other day, every other week, some other reason, no other way,
the other特指两者中的另外一个,复数为the others。如:
He held a book in one hand and his notes in the other.
Two students in our class failed, but all the others passed the exam.
2) another指“又一个,另一个”无所指,复数形式是others,泛指“别的人或事”如:
I don’t like this shirt, please show me another (on e).
The trousers are too long, please give me another pair / some others.
Some like football, while others like basketball.
5. all和both, neither和either
all表示不可数名词时,其谓语动词用单数。both和all加否定词表示部分否定,全部否定用neither和none.
All of the books are not written in English. / Not all of the books are written in English.
Both of us are not teachers. / Not both of us are teachers. / Either of us is a teacher.
