英语从句知识点 第1篇

引导词：though/although/as(虽然，尽管)，even if/though(即使，尽管)，whether/no matter (not)

(不管。。。是否，不管是。。。还是)wh-ever/no matter wh-(无论。。。)

注意：(1)though,although,as的区别

A、Though,although的主句中可以用yet, still, nevertheless,但不可使用but。

B、though引导的从句可以倒装，也可以不倒装;as引导的从句必须倒装;although引导的从句不能倒装。

其结构为：形容词/分词/副词/动词原形/名词(无冠词)+as/though+主语+谓语……

(2)though可用作副词，放在句末，意为“不过，但是”。Although无此用法。

(3)某些短语也引导让步的从句或短语，意为“尽管”，如：in spite of the fact that, despite the fact that, regardless of(the fact that)

一、 培养兴趣与自信

学习英语，要重视自己英语兴趣的培养，兴趣是最好的老师说的就是这个意思。如果能把学习变成一种兴趣，那么学习起来就相对更加轻松，也不会把学习英语当做是一种任务，而是满怀期待的去做这件事，才能够把事情做到最好。

同时还要建立自己的英语自信心，学英语不是一蹴而就的事情，即使你再感兴趣也会遇到各种难题，所以，要知道任何事情不是一帆风顺的，英语学习也是这样，要端正心态、正确认识自己的能力，保持积极的自信心。

二、 重视量的积累与质的飞跃

量的积累，就是告诉大家一定要多学习、多练习，多范围涉猎英语知识、了解更多的英语文化，就能掌握英语之间的关联性。

有了量的积累，想要把量变变成质变，就是要从多到好、好到精学习英语、积累英语知识，而不是永远重复最基本的知识。相信有了前面的积累，对英语的学习才能更好的深入。

三、 学以致用

学习英语就是拿来用的，只有把英语用到实处才能更明白英语的实际用处，把学习与生活连接起来。只有把理论与实践相结合才能把知识深深的装进脑海里，像母语学习一样，脱口而出。

英语从句知识点 第5篇

though, although

注意：
当有though, although时，后面的从句不能有but，但是 though 和yet可连用

Although it"s raining, they are still working in the

虽然在下雨，但他们仍在地里干活。

He is very old, but he still works very

虽然他很老，但仍然努力地工作。

Though the sore be healed, yet a scar may

伤口虽愈合，但伤疤留下了。

(谚语)

典型例题

1) ___she is young, she knows quite a

However Although Unless

答案：C。意为虽然她很年轻，却知道许多。

2)as, though 引导的倒装句

as / though引导的让步从句必须表语或状语提前(形容词、副词、分词、实义动词提前)。

Child as /though he was, he knew what was the right thing to

= Though he was a small child, he knew what was the right thing to

注意：
句首名词不能带任何冠词。

句首是实义动词，其他助动词放在主语后。如果实义动词有宾语和状语，随实义动词一起放在主语之前。

Try hard as he will, he never seems able to do the work

= Though he tries hard, he never seems…

虽然他尽了努力，但他的工作总做的不尽人意。

3)ever if, even 即使

4) whether…or- 不管……都

Whether you believe it or not, it is

No matter what happened, he would not

Whatever happened, he would not

替换：no matter what = whatever

no matter who = whoever

no matter when = whenever

no matter where = wherever

no matter which = whichever

no matter how = however

注意：no matter 不能引导主语从句和宾语从句。

(错)No matter what you say is of no use

(对)Whatever you say is of no use

你现在说什么也没用了。(Whatever you say是主语从句)

(错)Prisoners have to eat no matter what they"re given,

(对)Prisoners have to eat whatever they"re 囚犯们只能给什么吃什么。

英语从句知识点 第6篇

1、主语从句

(1)that从句作主语时，常用it作形式主语，常见的句型有：

It+be+形容词(obvious, true, natural, surprising,good,wonderful,funny,possible,likely,certain,probable,)+that从句

It+be+名词词组(no wonder, an honor, a good thing, a pity, no surprise, )+that从句

It+be+过去分词(said, reported, thought, expected, decided, announced, arranged, )+that从句

(2)that可以省略，但that从句位于句首时，that不能省略。

2、宾语从句

(1)常见的可以接that从句作宾语的动词有see, say, know, imagine, discover, believe, tell, show, think, consider, be sure, be afraid等。在可以接复合宾语的动词之后，如think, make, consider等，可以用it作形式宾语。

(2)That从句一般不能充当介词宾语，偶尔可作except, in 的宾语。

3、表语从句(that不可省略)

4、同位语从句

连词that引导同位语从句时，应在某些抽象名词之后，如：fact, hope, desire, thought, suggestion, idea, news, problem, possibility等，对前面的名词起补充说明的作用，that在从句中不担当任何成分，不能省略。

英语从句知识点 第7篇

1、介词如何确定

(1)依据定语从句中动词的习惯搭配来确定

(2)依据先行词的习惯搭配来确定

(3)根据意思来确定

(4)为了强调某一名词，不定式前加上关系词

2、关系代词作介词的宾语时，介词的位置

(1)whom和which可以和介词一起放在先行词和从句之间，也可以把介词放在从句中有关动词的后面。

(2)含有介词的短语动词一般不拆开，介词仍放在动词的后面。

(3)关系代词that在从句中作介词宾语时，介词不能放在它的前面，只能放在从句中有关动词的后面。

(4)关系代词whose也可以在从句中与它所修饰的名词一起作介词宾语。

3、“名词/数词/代词+介词+关系代词”结构常见的形式有：名词/one/two/some/none/all/both/several/many/most/a few/a little/the+比较级/the+最高级…+of+which/whom。

英语从句知识点 第8篇

引导词：if(如果)，unless(除非)，if only(只要，但愿)，only if(只有)，in case(万一)，suppose/supposing(that)

(假设)，provided/providing(that)(只要，假若)，on condition that(要是，在。。。条件下)，so/as long as(只要)，(let"s/let us)say(假设)

英语从句知识点 第9篇

比较：because, since, as和for

1)because语势最强，用来说明人所不知的原因，回答why提出的问题。当原因是显而易见的或已为人们所知，就用as或 since。

I didn"t go, because I was

Since /As the weather is so bad, we have to delay our

2)由because引导的从句如果放在句末，且前面有逗 号，则可以用for来代替。但如果不是说明直接原因，而是多种情况加以推断，就只能用for。

He is absent today, because / for he is

He must be ill, for he is absent

英语从句知识点 第10篇

引导词：so, so that, in order that, that, to the end that(以便，为了)，in case,for fear that,lest(以免，以防)，

目的状语从句中通常有情态动词can,could,may,might,should,would等。

注意：1、in case 还可表示“万一，假如”。

2、目的状语从句可以用so as to, in order to 等不定式代替，但主句和从句的主语必须一致。

英语从句知识点 第11篇

状语从句的时态

(1)当主句是一般将来时时，在时间、条件、让步等状语从句中用一般现在时表示将来的时间。

(2)when, before, after引导的从句的动作与主句动作的先后关系：若主从句的动作先后发生在过去，通常先发生的动作用过去完成时表示，后发生的动作用一般过去时。before, after本身已能表达动作的先后关系，所以在含有before, after从句的句子中，主从句的动作都可用一般过去时。

状语从句的语气 (见虚拟语气)

(1)as if /as though引导的从句以及if 。.(但愿，要是……就好了)句子的虚拟情况：用一般过去时表示对现在的虚拟，用过去完成时表示对过去的虚拟。

(2)if引导的非真实条件句中的虚拟情况。

状语从句的成分省略

在时间、条件、原因、让步、方式等状语从句中，当从句的主语与主句的主语相同，且从句中含有be动词时，我们可将从句的主语(或作主语的代词it)连同be动词一起省略。

状语从句的强调

not until引导的时间状语从句和because引导的原因状语从句可用于强调句型。句型构成分别是："It was not until that "和"It is/was because "。

英语从句知识点 第12篇

1)as, when 引导短暂性动作的动词。

Just as / Just when / When I stopped my car, a man came up to

2)当从句的动作发生于主句动作之前，只能用when 引导这个从句，不可用as 或 while。

When you have finished your work, you may have a

3)从句表示"随时间推移"连词能用as，不用when 或while。

As the day went on, the weather got

日子一天天过去，天气越变越坏。

英语从句知识点 第13篇

1)由从属连词that引导的从句叫做名词性that-从句。

That只起连接主句和从句的作用，在从句中不担任任何成分，本身也没有词义。名词性that-从句在句中能充当主 语、宾语、表语、同位语和形容词宾语，例如：

主语：That he is still alive is sheer 他还活着全靠运气。

宾语：John said that he was leaving for London on 约翰说他星期三要到伦敦去。

表语：The fact is that he has not been seen 事实是近来谁也没有见过他。

同位语：The fact that he has not been seen recently disturbs everyone in his

近来谁也没有见过他，这一事实令办公室所有的人不安。

形容词宾语：I am glad that you are satisfied with your

你对工作满意我感到很高兴。

2)That-从句作主语通常用it作先行词，而将that-从句置于句末，例如：

It is quite clear that the whole project is doomed to 很清楚，整个计划注定要失败。

It"s a pity that you should have to 你非走不可真是件憾事。

用it作形式主语的that-从句有以下四种不同的搭配关系：

It + be +形容词+ that-从句

It is necessary that… 有必要……

It is important that… 重要的是……

It is obvious that… 很明显……

It + be + -ed 分词+ that-从句

It is believed that…人们相信……

It is known to all that…从所周知……

It has been decided that… 已决定……

It + be +名词+ that-从句

It is common knowledge that… ……是常识

It is a surprise that… 令人惊奇的是……

It is a fact that… 事实是……

It +不及物动词+ that-分句

It appears that…似乎……

It happens that…碰巧……

It occurred to me that… 我突然想起……

英语从句知识点 第14篇

方式状语从句通常由as, (just) as…so…, as if, as though引导。

1) as, (just) as…so…引导的方式状语从句通常位于主句后，但在(just) as…so…结构中位于句首，这时as从句带有比喻的含义，意思是"正如…"，"就像"，多用于正式文体，例如：

Always do to the others as you would be done

你希望人家怎样待你，你就要怎样待人。

As water is to fish, so air is to

我们离不开空气，犹如鱼儿离不开水。

Just as we sweep our rooms, so we should sweep backward ideas from our

正如打扫房屋一样，我们也要扫除我们头脑中落后的东西。

2) as if, as though

两者的意义和用法相同，引出的状语从句谓语多用虚拟语气，表示与事实相反，有时也用陈述语气，表示所说情况是事实或实现的可能性较大。汉译常作"仿佛……似的"，"好像……似的"，例如：

They completely ignore these facts as if (as though) they never

他们完全忽略了这些事实，就仿佛它不存在似的。(与事实相反，谓语用虚拟语气。)

He looks as if (as though) he had been hit by

他那样子就像被雷击了似的。(与事实相反，谓语用虚拟语气。)

It looks as if the weather may pick up very

看来天气很快就会好起来。(实现的可能性较大，谓语用陈述语气。)

说明：as if / as though也可以引导一个分词短语、不定式短语或无动词短语，例如：

He stared at me as if seeing me for first

他目不转睛地看着我，就像第一次看见我似的。

He cleared his throat as if to say

他清了清嗓子，像要说什么似的。

The waves dashed on the rocks as if in

波涛冲击着岩石，好像很愤怒。

英语从句知识点 第15篇

连接词主要有 if, unless, as/so long as, on condition that 等。.

if 引导的条件句有真实条件句和非真实条件句两种。非真实条件句已在虚拟语气中阐述。

unless = if

Let"s go out for a walk unless you are too

If you are not too tied, let"s go out for a

典型例题

You will be late ___ you leave

unless until or

答案A。

句意：除非你立即走，否则你就回迟到的。可转化为 If you dong leave immediately, you will be 、D句意不对，or表转折，句子如为 You leave immediately or you will be
