八年级英语应该掌握的语法知识

发布时间:2020-12-30 00:45:12

A. 八年级英语 语法小知识

非常简单扼要的回答,供参考

cost: 多指物体的价值,价钱方面, 主语必须是物,而非人
如 The chair costs me $53.

spend:比较偏向于专人为的主观的花属费(多指时间),主语必须是人
如 I spent 6 days to study the working procere.

pay: 介于某种语境才会翻译为花费,基本上是当付钱,支付讲
如:I need to pay $33 for the book.

take: 一般当占用时间/空间/精力解释比较多
如:The project takes me too much time.

以上个人理解,仅供参考,比较通俗

G. 八年级英语需要掌握的语法有那些

一、词法

1、名词

A)、名词的数

我们知道名词可以分为可数名词和不可数名词,而不可数名词它没有复数形式,但可数名词却有单数和复数之分,复数的构成如下:

一)在后面加s。如:fathers, books, Americans, Germans, apples, bananas

二)x, sh, ch, s, tch后加es。如:boxes, glasses, dresses, watches, wishes, faxes

三)1)以辅音字母加y结尾的变y为i再加es 如:baby-babies, family-families, ty-ties, comedy-comedies, documentary-documentaries, story-stories

2)以元音字母加y结尾的直接加s。如:day-days, boy-boys, toy-toys, key-keys, ways

四)以o结尾加s(外来词)。如:radios, photos, 但如是辅音加o的加es:如: tomatoes西红柿, potatoes马铃薯

九)合成的复数一般只加主要名词,多数为后一个单词。如:action movie-action movies, pen pal-pen pals; 但如果是由man或woman所组成的合成词的复数则同时为复数。如:man doctor-men doctors, woman teacher-women teachers

十)有的单复数意思不同。如:fish鱼 fishes鱼的种类, paper纸 papers报纸,卷子,论文, work工作 works作品,工厂, glass玻璃 glasses玻璃杯,眼镜, orange桔子水 oranges橙子, light光线 lights灯, people人 peoples民族, time时间 times时代, 次数, chicken 鸡肉 chickens 小鸡

十一) 单个字母的复数可以有两种形式直接加s或’s。如:Is (I’s), Ks (K’s)。但如是缩略词则只加s。如:IDs, VCDs, SARs

十二) 特殊形式的有:child-children, man-men, woman-women, foot-feet, mouse-mice, policeman-policemen, Englishman-Englishmen

B)名词的格

当我们要表示某人的什么东西或人时,我们就要使用所有格形式。构成如下:

三、一般将来时

█一般将来时

1.be going to+ 动词原形~

对于将要发生的事,或打算、计划、决定要做的事情时,皆以be going to + 动词原形的句型来表示。

因此此句型有be动词,所以是否用am, is, are ,决定于主语。

1.肯定句:主语+be (is, am, are) going to +动词原形

I am going to play football next Sunday.

下周日我打算踢足球。

◇He is going to travel around the world. 他计划周游世界。

以今天为起点的所有将来时间,如:

this afternoon / this evening = tonight / tomorrow/

tomorrow morning / afternoon / evening ,

the day after tomorrow / next week ,

next Wednesday / next month,

next September / next year.

★ “be going to + 动词原形” 表示计划、打算、将来发生的动作,常和this afternoon (今天下午),this evening = tonight (今晚),tomorrow (明天),tomorrow morning (afternoon , evening ) (明早,午,晚),the day after tomorrow(后天),next Sunday (下个星期天), next week (下周), next month (下个月), next year (明年)等的时间状语连用,前不加任何介词。另外,动作性动词go ,come 和leave 等的现在进行时表示一般将来时动作。

四、形容词和副词的比较级和最高级

1.比较级:句子表示两者之间的比较时用比较级,其标志词是than, much, a little , even和still等。

e.g. ① Her hair is much longer than mine. 她的头发比我的长多了。

② I’m a little older than you. 我比你大一点儿。

2.最高级:句子表示三者或多者的比较时用最高级,其标志词是表示范围的in…或of …介词短语。在句子中,形容词最高级前必须加the。

e.g. ① The boy is the tallest in our class. 这个男孩是我们班最高的。

② Which is the biggest, the sun, the moon or the earth?

★形容词的比较级和最高级:

形容词有三种等级:原级、比较级、最高级。

3.原级:句中只有一者时用原级,其标志词是very, so, too, quite等。

e.g. His handwriting is very good.他的书法很好。 (一个人不作比较。)

★ 形容词比较级和最高级的构成:

1.一般在原级后加er 构成比较级,加est构成最高级。

e.g. small smaller smallest
young younger youngest

2.以不发音的字母e 结尾的形容词,直接加r 或st 构成比较级和最高级。

e.g. nice nicer nicest
late later latest

3.以辅音字母+y 结尾的形容词,变y为i ,再加er 或est, 构成比较级和最高级。

e.g. busy busier busiest
heavy heavier heaviest

4.在重读闭音节中,末尾只有一个辅音字母的形容词,要先双写这个辅音字母,再加er或est, 构成比较级和最高级。

e.g. hot hotter hottest
big bigger biggest

5.个别形容词的比较级和最高级是不规则变化,需个别记忆。

e.g. good (well) better best
bad (badly, ill) worse worst
many (much) more most
little less least
far farther farthest
或 further furthest

★ 副词的比较级和最高级:

1.以ly 结尾的副词,除early 变为 earlier 和 earliest 外, 其余一律在其前加more 和most。 如:carefully – more carefully – most carefully

2.规则变化直接加er 和 est 。 如:fast – faster—fastest

3.个别词是不规则变化,需要特别记忆。

4.句子中,副词最高级前的the 可省略也可以不省略,但形容词最高级前面的the 绝对不能去掉。
e.g. Who runs (the) fastest, Tom, Jim or Mike?

五、提建议的表达方法、表示需要、询问方向、指点方向

★ 表示建议的基本句型

1. Shall I / we + 动词原形?

2. Why don’t you + 动词原形 = Why not + 动词原形

3. Let’s + 动词原形

4. What/ How about + doing sth.

★ 表示需要的基本句型

⑷ It’s about a hundred metres along on the left. 它在左前方大约一百米处。

⑸ Turn right / left. = turn to the right / left. 向右/左拐。

六、一般过去时

◆一般过去时主要表示过去的动作或状态。在句子中由主语+动词的过去式来表达。

1.He walks to school. (一般现在时)

2.He walked to school. (一般过去时)

例如:
例1.中的动词walks时现在式, 由于主语是第三人称单数he, 因此原因的walk必须加上 “s”,表示目前习惯性、经常性动作。可译为“他现在经常步行上学”。

例2.中的动词walked是过去式,过去式是叙述过去事情的动词形式,所以这句话时表示的是过去的某时,例如昨天、上周或学生时代等过去的某一时间,这句可译为“他曾经步行上学”。

◆be 动词的过去式

be 动词的过去时的句型如下:

肯定句: 主语 +be动词的过去式(was, were)~

否定句: 主语 + be动词的过去式(was, were)+ not ~

疑问句: be动词的过去式(was, were)+ 主语 ~?

○He was busy yesterday. (肯定句) 他昨天很忙。

○He was not busy yesterday. (否定句) 他昨天不忙。

○Was he busy yesterday? (疑问句) 他昨天忙吗?

1.be动词过去时的肯定句
Mike was in the United States last year. 麦克去年在美国。

比较be 动词的现在式和过去式:

There is (are ) 的句型用于一般过去时需把is ,are 变为它们的过去式:There was (were) …

2.be动词过去式的否定句
He was not in Canada last year.
他去年不在加拿大。

be动词过去时的否定句的结构和现在时一样,只要在be动词过去式(was, were)后面加上not就可以了。否定式的was not , were not 大多使用缩写形式wasn’t 和 weren’t .

○I wasn’t busy the other day.
前几天我不忙。

3.be动词的过去时的疑问句(一般疑问句/特殊疑问句)
Was it raining in Beijing yesterday?
No, it wasn’t . I t was cloudy.
昨天北京下雨了吗?不,没下雨。昨天北京阴天。

be 动词过去时一般疑问句的结构和一般现在时一样,只要把be 动词的过去式was, were 调到主语前面即可。 was (were ) + 主语 ~? 回答时,需要用Yes, … was (were) .或 No… wasn’t (weren’t)

○Was your father free this morning? 今天上午你爸爸有空吗?
Yes, he was . 是的,他有空。
No, he wasn’t . 不,他没空。

◆一般动词的过去时

一般动词过去式的基本句型如下:

肯定句: 主语+ 动词的过去式~

否定句: 主语+ did not + 动词原形~

疑问句: Did + 主语 + 动词原形~?

○He played tennis last week. (肯定句) 他上周打网球了。

○He did not play tennis last week. (否定句) 上周他没打网球。

○Did he play tennis last week? (疑问句) 上周他打网球了吗?

1.一般动词过去式的肯定句
We had a good time yesterday.
昨天我们过得很愉快。

He had a good time yesterday.
昨天他过得很高兴。

一般过去时没有人称和数的变化。因此,主语即使是单数、第三人称,也和其他人称一样变化。

○I watched TV for an hour.
我看了一个小时的电视。

○She studied Russian two years ago.
两年前他学俄语。

2.一般动词过去时的否定句

We did not have a good time yesterday.
昨天我们过得不好。

一般动词过去时的否定句的结构和一般现在时够定句的结构一样, 不论主语是第几人称,还是单、复数,在主语后面加上did not (而不是do not ,或 does not)就可以了。

否定式did not 常用缩写形式didn’t 。

○He didn’t have classes this morning.
今天上午他没课.

○You didn’t do your best to do it.
你没有尽力去做。

3.一般动词过去时的疑问句

Did he go there?
他去那了吗?

Yes, he did. (No, he didn’t .) 是的,他去了。 (不,他没去。)

When did you get up this morning? At six.
今天早晨你几点钟起床的? 六点钟。

一般动词过去时一般疑问句的结构和一般现在时一般疑问句的结构一样,无论主语是第几人称,单数、复数,在主语前面加上did即可。

○Did Tom go with you?
汤姆和你一起去的吗?

Yes, he did . (No, he didn’t .)
是的。(不,不是的)

○How many subjects did you study last term?
上学期你们学习几门功课?

We studied seven.
我们学习七门课。

比较一般动词的现在时和过去时

一般现在时
一般过去时

肯定句
I go ~.

He goes ~.
I went ~.

He went ~.

否定句
I don’t go ~.

He doesn’t go ~.
I didn’t go ~.

He didn’t go ~.

疑问句
Do you go ~?

Does he go ~ ?
Did you go ~?

Did he go ~?

◆一般过去时的基本用法

1.带有确定的过去时间状语时,要用过去时

如:yesterday (昨天) , two days ago(两天前), last year(去年)., the other day(前几天), once upon a time(过去曾经) , just now(刚才), in the old days(过去的日子里), before liberation(解放前), when I was 8 years old(当我八岁时).

2.表示过去连续发生的动作时,要用过去时

这种情况下,往往没有表示过去的时间状语,而通过上下文来表示。

○The boy opened his eyes for a moment, looked at the captain , and died.
那男孩把眼睛张开了一会儿,看看船长,然后就去世了。

3.表示过去一段时间内经常反复的动作。

常与always, never 等连用。

○Mrs. Peter always carried an umbrella.
彼得太太过去老是带着一把伞。
(只是说明她过去的动作,不表明她现在是否常带着伞。)

试比较:
○Mrs. Peter always carries an umbrella.
彼得太太老是带着伞。
(说明这是她的习惯,表明她现在仍然还习惯总带着一把伞。)

○I never drank wine.
我以前从不喝酒。
(不涉及到现在,不说明现在是否喝酒。)

4.如果强调已经终止的习惯时要用used to do

○He used to drink.
他过去喝酒。
(意味着他现在不喝酒了。喝酒这个动作终止了。)

5.有些句子,虽然没有表示过去确定时间的状语,但实际上是指过去发生的动作或存在的状态的话,也要用过去时,这一点,我们要特别注意。

○I didn’t know you were in Pairs.
我不知道你在巴黎。
(因为在说话时,我已经知道你在巴黎了。这句话指的是说话前,所以只能用过去时表示。实际上,这句话暗指:But now I know you are here.)

○I thought you were ill.
我以为你病了呢。
(这句话应是在说话前,我以为你病了,但是现在我知道你没病。)

七、反意疑问句
█.反意疑问句 (Tag questions)

在陈述句之后加上一个意思与之相反的简短问句,这种句子叫做反意疑问句。反意疑问句必须由意思相反的两部分组成,在前一部分(陈述句)之后用逗号,后一部分(简短问句)之后用问号。反意疑问句的否定句必须用缩略形成,同时它的主语必须用人称代词,不能用名词。前一部分用降调,后一部分在表示疑问句时用升调。

反意疑问句分为两类:

1.前一部分为肯定式,后一部分是否定式。

2.前一部分为否定式,后一部分是肯定句。

★陈述句(肯定式),+ 疑问部分(否定式)?

1.be 动词和一般动词(实意动词)构成的反意疑问句

be动词句型
现在…… ,isn’t (aren’t ) + 主语?
过去……, wasn’t (weren’t ) + 主语?

一般动词句型:
现在…… , don’t (doesn’t ) + 主语?
过去…… , didn’t + 主语?

◇The pen is yours, isn’t it?
这笔是你的,不是吗?

◇Lucy likes English, doesn’t she?
露西喜欢英语,不是吗?
Yes, she does. 是的,她喜欢。
No, she doesn’t 不,她不喜欢。

2.情态动词的反意疑问句

◇Your brother can swim, can’t he?
你的哥哥会游泳,不是吗?
Yes, he can.
No, he can’t.

◇We have to finish it, don’t we?
我们不得不完成它,不是吗?
Yes, we do.
No, we don’t.

◇The workers had to take the first bus, didn’t they?
工人们不得不上头班车,不是吗?
Yes, they did.
No, they didn’t.

★陈述句(否定式),+ 疑问句(肯定句)?

这种反意疑问句的结构和第一部分一样,只不过颠倒一下肯定句和否定句的位置。 这部分的难点在于回答,回答和汉语习惯不同。 在这种问句中,先不要管yes和no ,按实际情况,如果答语是肯定式的,就要用Yes + 肯定结构,如果答语是否定的,就要用No+ 否定结构

◇You aren’t a teacher, are you?
你不是老师,是吗?
Yes, I am. 不,我是。
No, I am not. 是的,我不是。

◇You don’t study Chinese, do you?
你们不学中文,是吗?
Yes, we do. 不,我们学中文。

◇Your classmates didn’t have a good time last summer, did they?
你的同学们去年暑假没过好,是吗?
Yes, they did. 不,他们过得很好。
No, they didn’t. 是的,他们过的不好。

★其他类型的反意疑问句

1.祈使句的反意疑问句

a.在肯定的祈使句后,为了使祈使句听起来比较婉转、客气,可加一个简短的问句,如:Will you? would you? won’t you? can you ? could you ? can’t you?最常见的是will you ?或 won’t you?

◇Open the window, will you?
请打开窗子,好吗?

b.在let’s 祈使句后加上shall we? 或 shan’t we? 在let us (me , him…)后加上will you? 或won’t you?

2.陈述部分如果有表示否定意义的某些词,如:never, seldom, hardly, few, little, nobody, no one, nothing, neither…,疑问部分必须用肯定式。

3.陈述部分是there be 结构时,疑问部分用there,省略主语代词。

4.陈述句部分如果有everything, nothing …. 表示事物的词作主语时,疑问部分的主语用it ,陈述部分如果有everyone , no one, someone ….. 表示人的不定代词作主语时,疑问部分常用they (有时也用he).

◇Everything here is dirty, isn’t it?
这的所有东西都脏,不是吗?

八、邀请和应答、请求许可

█英语中表达请求允许的句型很多,在不同的场合要用不同的句式来表达。

1.常见表示“请求”“允许”的句式。

① May I …? 我可以干……吗?

② Can / Could I … ? 我能干……吗?

③ Shall I / we … ? 我/咱们干……好吗?

④Would you like / love to …? 你愿意干……吗?

⑤Will (would) you please…? 请你干……好吗?

④Yes, please. 好的,请(做吧)。

⑤I’d love / like to. 很乐意。

⑥With pleasure. 很乐意。

⑦Good idea! 好主意。

3.表示“不允许”的答语有:
