八年级英语连词语法知识点 篇1

6.从属连词

从属连词用来引导从句。常见的从属连词有：

(1)引导时间状语从句的after, before, when, while, as, until, till, since, as soon as等。(2)引导条件状语从句的if, unless等。

(3)引导原因状语从句的because, as, since等。

(4)引导目的状语从句的so that, in order that等。

(5)引导让步状语从句的though, although, even if等。

(6)引导结果状语从句的so that, so…that, such…that等。

(7)引导比较状语从句的than, as…as等。

(8)引导名词从句的that, if , whether等。

7.常用连词的用法辨析

(1)while, when, as

这三个连词都可引导时间状语从句，但用法有所不同。

1)当某事正在进行的时候，又发生了另一件事。While, when, as 都可用来引导表示“背景”的时间状语从句。例如：

As/When/While I was walking down the street I noticed a police car.

2)当两个长动作同时进行的时候，最常用的是while。例如：

While mother was cooking lunch, I was doing my homework.

3)当两个动作都表示发展变化的情况时，最常用的是as。例如：

As children get older, they become more and more interested in things around them.

4)当两个短动作同时发生时，或表示“一边…一边…”时，最常用as。例如：

Just as he caught the fly, he gave a loud cry.

She looked behind from time to time as she went

5)当从句的动作先于主句的动作时，通常用when。例如：

When he finished his work, he took a short rest.

6)当从句是瞬间动作，主句是延续性动作时，通常用when。例如：

When John arrived I was cooking lunch.

(2)as, because, since , for

这四个词都可表原因，但用法有区别。

1)如果原因构成句子的最主要部分，一般用because。因此，because引导的从句往往放在句末。例如：

I stayed at home because it rained.

---Why aren’t you going?

---Because I don’t want to.

2)如果原因已被人们所知，或不如句子的其它部分重要，就用as或since。Since比as稍微正式一点。As和since 引导的从句一般放在句子的开头。例如：

As he wasn’t ready, we left without him.

Since I have no money, I can’t buy any food.

3)for用来补充说明一种理由，因此，for引导的从句几乎可以放在括号里。For引导的句子不放在句子的开头。例如：

I decided to stop and have lunch----for I was feeling quite hungry.www.zhongkao5.com//

(3)if, whether

if和whether都可作“是否”讲，在引导宾与从句是一般可互换。例如：

I wonder whether (if) you still study in that school.

I don’t know whether (if) he likes that film.

在下列情况下，只能用whether,不能用if：

1)引导主语从句时。例如：

Whether he will come to the party is unknown.

2)引导表语从句时。例如：

The question is whether I can pass the exam.

3)在不定式前。例如：

I haven’t made up my mind whether to go there or not.

(4)so…that, such…that

1)so…that中的so是个副词，其后只能跟形容词或副词，而such…that中的such是个形容词，后接名词或名词短语。例如：

I’m so tired that I can’t walk any farther.

It was such a warm day that he went swimming.

2)如果在名词之前有many, much, little, few时，用so,不用such。例如：

He has so little education that he is unable to get a job.

I have had so many falls that I am black and blue all over.

(5)either…or…， neither…nor, not only…but also…

这三个连词词组都可连接两个并列成分。当它们连接两个并列主语时，

谓语动词要随相邻的主语变化。例如：

Either you or he is wrong.

Neither he nor his children like fish.

Not only the teacher but also the students want to buy the book.

(6)although, but

这两个连词不能用在同一个句子中。例如：我们不能说“Although he is

over sixty, but he works as hard as others.”这个句子应改为：Although he is over sixty, he works as hard as others.或He is over sixty, but he works as hard as others.

(7)because, so

这两个连词同样不能用在同一个句子中。例如：我们不能说“Because John

was ill, so I took him to the doctor.” 这个句子应改为Because John was ill, I took him to the doctor.或John was ill, so I took him to the doctor.

1、词类

(1)实词：表示实在意义，能作短语或句子的成分，一般能独立成句。实词包括名词、动词、形容词、数词、量词、代词。

(2)虚词：一般不表示实在的意义，基本用途是表示语法关系。虚词包括副词、介词、连词、助词、叹词和拟声词。

2、短语

(1)并列短语：由两个或由两个以上的名词、动词或形容词等并列组成的短语，基本结构有名+名、名+代、代+代、动+动、形+形、数量+数量。

(2)动宾短语：动词后边带上一个受动词支配的词，组成一个短语，这种短语叫做动宾短语。基本结构：动+名、动+代。

(3)补充短语：包括动补短语和形补短语两大类。

(4)介宾短语：由介词和它的宾语构成的短语。

(5)“的”字短语：由动词、形容词、动宾短语加上“的”构成。基本结构：动词+的、形容词+的、动宾短语+的。

还有“主谓短语”和“偏正短语”。

3、语素

(1)自由语素：可以独立成词，位置自由。如“分、好、高、低”;

(2)半自由语素：不能独立成词，只能组合，位置自由。如“话、习、确、民”;

(3)不自由语素：不能独立成词，位置固定。如“者、第、阿”。

4，语法知识点

语法=词法+句法;语法是连接古今汉语的时空隧道。

阅读古文的三大障碍：眼花缭乱的词类活用;体系庞杂的文言虚词;纷繁变幻的文言句式。但是，理解了汉语语法，这一切都不再是障碍。所以，学语法不是为了懂语法，而是为了读懂文言文。

八年级英语连词语法知识点 篇9

一、比较级的定义：大多数的形容词都有三个级别：原级、比较级、最高级。其中比较级表示“更……”，用于两者之间的比较，用来说明“前者比后者更……”，比较级前面一般用much, even, a little修饰，其中even, much 只能修饰比较级。

二、比较级的构成：（1）规则变化：

①单音节和部分双音节的形容词一般在词尾加-er Eg: calm---calmer tall---taller smart---smarter ②以字母e结尾的直接在词尾加-rEg: nice---nicer fine---finer large---larger ③以“辅音+y 结尾的词，变y为 i，再加-er”Eg: early---earlier happy---happier busy---busier ④以重读闭音节的单个辅音字母结尾的词，双写辅音字母，再加-erEg: big---bigger thin---thinner hot---hotter ⑤多音节或部分双音节的形容词在原级前面加moreEg: popular---more popular important---more important（2）不规则变化：少数形容词的比较级变化是不规则的：

good→better→best well→better→bestbad→worse→worstill→worse→worst old→older/elder→oldest/eldest many/much→more→most little→less→least far →further/farther→ furthest/farthest

三、比较级的用法:

(一)当两个人或事物（A和B）进行比较时，我们需要用到形容词（副词）的原级或者比较级

1．表达“A和B一样”，用as…as的结构。

公式: A+be动词+as+形容词原级+as…+B;A+实义动词+as+副词原级+as…+B

Eg:I am as tall as you.我和你一样高。He runs as fast as I.他跑得和我一样快。

2．表达“A不如B”用not as…as的结构。

公式: A+be动词的否定形式+as+形容词原级+as…+B;A+助词的否定形式+动词+as+形容词原级+as…+B Eg:I am not as tall as you.我没有你高。He doesn’t run as fast as I.他没有我跑得快。3．表达“A大于B”用“比较级+than”的结构。

公式: A+be动词+形容词比较级+than+B…;

A+实义动词+副词比较级+than+B… Eg：I am taller than you.我比你高。He runs faster than I.他跑得比我快。

(二)关于形容词、副词比较级的更多用法

1．比较级前面可以加上表示“优劣程度”的词或短语，是“更…”，“…得…”。常见much, a little, even, a lot, a great deal等。

Eg：He is much taller than I.他比我要高得多。I jump a little higher than he.我跳得比他高一点点。想一想，这些词能修饰形容词或副词的原级吗？

2.比较级前面可以加上表示具体数量差别的结构,表示具体“大多少”，“小多少”，“长多少”，“短多少”等。Eg：I am two years older than he.我比他大两岁。This building is 20 meters higher than that one.3．“比较级+and+比较级”表示“越来越……”。

It is getting warmer and warmer．天气越来越暖和。He is running faster and faster．他跑得越来越快。

0ur country is becoming more and more beautiful．我们祖国越来越美了。

4．“the more…，the more…”表示“越……，就越……”，The more，the better.多多益善。

The more careful you are,the fewer mistakes you will make.你越细心，犯错就越少。

5．“the more…of the two…”表示“两个当中较。。的一个”

The taller of the two boys is my brother.四、当三个或三个以上的人或事物进行比较时，我们需要用到形容词（副词）的最高级

1．表达“…是…中最…的”,用“the+形容词（副词）的最高级”的结构。后面可以加上表示范围的介词短语或从句。

公式：主语+be动词+the +形容词最高级+（名词）+表示范围的介词短语或从句

主语+实义动词+（the）+形容词最高级+表示范围的介词短语或从句

Eg:He is the tallest(student)in our class.He jumps the highest of the three boys.This is the best book that I have ever read.2．表示“最…的…中一个”，用“one of +the +最高级+复数名词”的结构来表达。

Eg：He is one of the best students in our class.他是我们班最好的学生之一。

This is one of the most beautiful flowers in the garden.这是花园里最漂亮的花之。

注意：(一)形容词的最高级前面有定冠词the , 而副词的最高级前面定冠词the可以省略。但在形容词最高级前有物 1

主代词时，不能要定冠词the.（二）常见的用来表示范围的介词有in, of, among

五、运用形容词、副词比较级应当注意的问题：

(一)、按语法规则，than后面的人称代词应当用主格，但口语当中有时会用宾格代替主格。

Eg：He is more careful than I(me).(二)、只有同类的事物才能比较

Eg：Her bag is bigger than mine.不能说 Her bag is bigger than I.The weather of Kunming is much better than that of Shenyang.不能说The weather of Kunming is much better than Shenyang.注意:

(1)形容词最高级前通常必须用定冠词 the，副词最高级前可不用。例句: The Sahara is the biggest desert in the world.(2)形容词most前面没有the，不表示最高级的含义，只表示“非常”。

It is a most important problem.=It is a very important problem.二、形容词、副词的比较级和最高级的用法

1.“A + be +形容词比较级 + than + B” 意思为“A比B更……”。

如:This tree is taller than that one.这棵树比那棵树高。

注意: ① 在含有连词than的比较级中，前后的比较对象必须是同一范畴，即同类事物之间的比较。

②be+...year(s)older than

I am two years older than him

2.“比较级 + and + 比较级”或“more and more +原级”表示“越来越……”

如:It is getting warmer and warmer when spring comes.春天来了，天气变得越来越暖和了。

The wind becomes heavier and heavier.风变得越来越大。

Our town is becoming more and more beautiful.我们的学校变得越来越美丽。

3.在含有or的选择疑问句中，如果有两者供选择，前面的形容词要用比较级形式。

如:Who is taller,Tim or Tom? 谁更高，Tim还是Tom? 4.“the +比较级……, the+比较级”，表示“越……越……”。

The more money you make, the more you spend.钱你赚得越多，花得越多。

The sooner，the better.越快越好。

5.表示倍数的比较级用法: ①.A is …times the size /height/length/width of B.如:The new building is three times the height of the old one.这座新楼比那座旧楼高三倍。(新楼是旧楼的四倍高)②.A is …times as big /high/long/wide/large as B.如:Asia is four times as large as Europe.亚洲是欧洲的四倍大。(亚洲比欧洲大三倍)③.A is …times larger /higher/longer/wider than B.如:Our school is twice bigger than yours.我们学校比你们学校大两倍。

6.形容词、副词的最高级形式主要用来表示三者或三者以上人或事物的比较，表示“最……”的意思。

句子中有表示范围的词或短语。如:of the three, in our class等等。

如:Of the three, he is the most hard-working.He is the tallest in our class.7.“否定词语+比较级”，“否定词语+ so… as”结构表示最高级含义。

Nothing is so easy as this.=Nothing is easier than this.=This is the easiest thing.8.比较级与最高级的转换: 比较级+than+any other+单数名词

Mike is the tallest in his class.Mike istallerthan any other student in his class 7.修饰比较级和最高级的词

1)可修饰比较级的词a bit, a little, much, a lot, even 注意: 使用最高级要注意将主语包括在比较范围内。

(错)Tom is the tallest of his three brothers.(对)Tom is the tallest of the three brothers.2)下列词可修饰最高级:by far(非常,远远超过,远比), far, much, mostly, almost。

This hat is nearly / almost the biggest.注意: a.very可修饰最高级，用于形容词最高级前，以加强语气(完全地，真正地)This is the very best.b.序数词通常只修饰最高级。Africa is the second largest continent.8.要避免重复使用比较级。

(错)He is more cleverer than his brother.(对)He is more clever than his brother.(对)He is cleverer than his brothe

9.要避免将主语含在比较对象中。

(错)China is larger that any country in Asia.(对)China is larger than any other country in Asia.10.要注意对应句型，遵循前后一致的原则。

The population of Shanghai is larger than that of Beijing.It is easier to make a plan than to carry it out.11.要注意冠词的使用，后有名词的时候，前面才有可能有名词。

比较:Which is larger, Canada or Australia? Which is the larger country, Canada or Australia?

She is taller than her two sisters.She is the taller of the two sisters.形容词副词比较级和最高级专练
