初中英语语法讲座讲课讲稿

初中英语语法讲座
这一讲里，主要帮助同学们掌握名词、冠词、数词的用法，特别是针对同学不易掌握的方面。

一、名词
关于名词，我们必须掌握名词的数，名词的格。

单数---可用a、an来修饰可数名词单数，在元音发音开头的单词前用an，而不是a
可数名词
名词的根据数复数
不可数名词
1.复数的构成方法：
(1)一般在复数名词后加s，如：dog--dogs。

(2)以s、x、ch、sh结尾的名词加es，如：watch--watches。

(3)以辅音字母加y结尾的名词，变y为i加es，如：country--countries。

请区别：如果是元音字母加y结尾的名词，则只须加s如：monkey--monkeys。

(4)以o结尾的名词，只有potato(土豆)，tomato(西红柿)加es 构成复数。

(5)以f、fe结尾的名词，变f、fe为v再加es，如：knife--knives。

2.单复数形式相同的词：sheep--sheep，fish—fish, Chinese--Chinese，Japanese--Japanese
3.特殊变化的单词有：(1)tooth--teeth，foot-- feet
(2)man--men，woman--women，policeman--policemen, Frenchman--Frenchmen
请区别：German(德国人)--Germans
(3)child—children
4.常以复数形式出现的名词：people(人)，clothes(衣服)，trousers(裤子) glasses(眼镜) ,这些名词作主语时，同学们应特别注意它们的谓语，用复数。

如：My clothes are (be) newer than yours.
5.有些名词看似复数形式，实际上是单数。

这一点是同学不易掌握的，应特别加以记忆。

如：news(消息)，maths(数学)，physics(物理)
No news is good news.
6.可用how many，many，a few，few，a lot of，lots of，some，any等来修饰可数名词复数。

How many are there in your pencil-box? (knife)
不可数名词：
1.常见的不可数名词有：water，rice，fish，meat，等。

应特别记medicine,news,work,homework,housework,money,chalk,weather,cotton,wood.
2.不可数名词无复数，作主语时常看成单数。

如：Some bread over there. (be)
3.常用how much, much, a little, little, a lot of ,some, any等来修饰不可数名词。

4.常用a piece of, a cup of等来表示不可数名词的量。

如要表达“两片面包”这样的意义，bread仍为不可数名词，不加s，而piece则可加s。

即：two pieces of bread
请区别：可数名词也可用量来表示，如：三箱苹果three boxes of apples
例： 1、These two pieces of bread are over there.(be)
2、Could I have three ,please？
A. piece of bread
B. .piece of breads
C. pieces of bread D .pieces of breads
名词的格
名词所有格的构成方法，在名词后加“ 's”。

如：Tom→Tom's译为“…的”，若遇上以s结尾的复数名词，则在s后加“ '”即可。

如：Teachers' Day , two weeks' holiday，而不以s结尾的复数名词的所有格，仍按惯例加's 。

如：Children's Day
关于名词所有格，应掌握以下几点：
1.可用名词所有格表示地点。

如：my aunt's 我姑姑家。

go to the doctor's 去医生家。

2.表示两人共同拥有，在最后一个名词后加's如：Lucy and Lily's 露西和莉莉的
3.掌握词组：a girl of five 一个五岁的女孩 a friend of mine 我的一个朋友
eg ; The white shirt is and blue one is
A、Kate ,my B .Kate's ,mine C .Kate ,mine D .Kate's, my
二、冠词
冠词是词汇中的基础的，也是简单的部分，所以同学们有必要掌握其基本用法，中考也会体现这一点。

归纳起来，同学们应该掌握以下几点：
1.冠词指不定冠词a, an和定冠词the
2.不定冠词an常用于元音发音开头的词前，如：an hour, an English car. 请区别：a useful machine
3.指上文提到过的人或物，用定冠词the
4.在世界上独一无二的事物前用定冠词the.如：the sun ,the moon, the earth
5.定冠词the用于序数词前，表示方位的名词和形容词最高级前。

如：the first, the best ,in the south
6.在复数姓氏前加the，表示××一家人，常看成复数。

如：The Browns are going to Shanghai for a holiday this summer.
7.在介词短语中常用定冠词the，如：in the box ,behind the chair
8.特别注意不能用定冠词the的几个方面：
(1)在节日、星期、月份、季节、年等词前不用冠词。

如：in summer, in August 请区别：in the spring of 1945. (这里表示特指，故加the)
(2)一日三餐和球类运动名不用冠词。

如：have breakfast ,play football
(3)一些固定词组中，如：go to bed ,go to school ,by bus ,,at night.
9.在有些词组中，有冠词和无冠词意思不同，请注意区别：
in front of 在…前面 in the hospital 在医院里
in the front of 在…范围内的前部 in hospital (生病)住院
There's 800-metre-long road behind hospital.
A. an, an B .a, a C .an, the D. a, the
三、数词
同学们首先应会读会写所有基数词和序数词，以及与数词有关的钟点表达法。

对数词的考查，中考常采用单选题及听力题，这些题型归纳起来，应掌握以下几点特别容易出错的地方。

1.基数词变序数词。

其规律为：
1,2,3特殊记，加th 从4起 (first, second, third, fourth)
8少t，9去e，千万别忘记 (eighth ,ninth)
逢5逢12，ve变f (fifth ,twelfth)
20到90，y要变ie (twentieth ,ninetieth)
若是几十几，前基后序别倒位 (ninety-first)
2.hundred,thousand,million 在构成具体的数字时用单数形式。

如：five hundred people.
只有在表达笼统的多数时才加s，构成复数形式。

hundreds of 数以百计的，成百上千的
thousands of 数以千计的，成千上万的
millions of 数百万的
这些词组前不能用具体数字。

3.序数词常与定冠词the 连用。

eg: Henry has learned eight French words this year.
A. hundred
B. hundreds C .hundred of D .hundreds of
The lesson is the most difficult one in Book Two. (twenty)
另外，同学们还应掌握与数词有关的钟点表达法。

顺读法(钟点＋分钟) 如：4:30 four thirty 4:45 four forty-five
4:15 four fifteen
倒读法(分钟＋to／past＋钟点) 如：4:30 half past four
4:15 fifteen past four／a quarter past four
4:45 fifteen to five／a quarter to five

C. at
D. over
七、连词
1．并列连词
both…and 既~又~谓语用复数动词
neither…nor 既不~也不~含否定意义，（就近原则）谓语动词由靠近它的那个主语来决定单复数。

either…or… “或者…或者…”“不是…就是…”
and“和”连接两个并列成分,连接谓语时,两个动词时态应一致。

but “但是” 表转折，不能与 though 同时出现在句中。

or “或者”在否定句中，并列句中的列举常用 or，而不用 and。

2．引导宾语从句的连词

4．引导时间状语从句的连词：
A. when（当…时候），as soon as…（一…就），not…until（直到…才），after（在…之后），引导的主从复合句，主句为一般将来时，从句则用一般现在时来代替一般将来时。

eg: I won't leave until he comes back.
B. since（自从…以来）引导的主从复合句，主句为现在完成时，从句用一般过去时。

eg：We haven't met each other since she left here last year.
C. while（当…时候，一边…一边…）它引导的时间状语从句常用进行时态。

eg: My father came in while I was doing my homework.
5．引导条件状语从句的连词：
if “如果”，引导条件状从，主句用一般将来时，从句则用一般现在时。

请区别于if“是否”相当于 whether，引导宾语从句，时态根据语境确定
eg:1)I don't know if it (rain) tomorrow.
2)If it ______ (rain) tomorrow, I _____________ (not climb) the hills.
3)Joan and Mary haven't seen each other ___they left school five years ago.
A. as

八、动词
可以分为四类：实义动词（或称行为动词）连系动词、情态动词以及助动词。

一、实义动词（行为动词）
1.不及物动词:不能直接跟宾语,常须加了介词后方能加宾语
如:look at (for, after), get to (on), operate on, hear of, hear from, point to (at), worry about, knock at, play with, think about等
2.及物动词:后面必须跟宾语,意义才完整
在及物动词+副词构成动副搭配时,代词放中间这一点同学们常易忘记,故应特别加以记忆。

如:turn on(√) turn on the radio(√) turn the radio on(√)turn on it(×) turn it on(√)
常见的动副搭配的词组有：put on, pick up, look up, wake up, try on, write down, move away, take away 等
3.注意行为动词的几种变化形式
原形 enjoy
第三人称单数 enjoys
过去式enjoyed
过去分词enjoyed
现在分词enjoying
象过去式，过去分词，同学们须熟记初中所学的不规则动词变化表。

现在分词的变化方法，一般是直接在动词后加ing，有几个特殊的可加以记忆：lie-lying, die-dying
要双写的单词有：
一个m(swim-swimming)
一个g(dig-digging)
三个n(run-running, win-winning, begin-beginning)
三个p(stop-stopping, shop-shopping ,drop-dropping)
还有六个t(sit-sitting, hit-hitting，get-getting, let-letting, put-putting, forget-forgetting) 同学们特别应注意forget, begin这种双音节单词。

另外，eat, wait这两个词不是重读闭音节，故不能双写加ing，这也是同学们易犯的错误。

4.请区别几组易混淆的同义动词
