如何区分 状语从句 名词性从句 定语从句 还有，从句是指哪一部分
从句就是一个完整的句子，有主谓宾或者主系表的。
状语从句就是这个从句在句子中充当状语的成分。定语从句通常都是which引导的。
状语类似副词的作用，定语类似形容词的作用。
名词性从句就是从句作名词的作用。
【That light travels in straight lines】 is known to all. 句子前面是一个主语成分，是主语从句也是一个名词从句，主语通常是名词。
This is 【what we are looking for】. 括号里面是宾语也是名词，句子缺乏了宾语，所以可以说是宾语从句。
定语从句建议记着关系词就能判断出来。
关系词： 引导定语从句的词，分为关系代词（who,whom,that,which,whose）和关系副词(where,when,why,)。
This is the pen 【which was given by my friend】.
定语类似形容词的作用的意思就是，例如上面这个句子，which修饰the pen， 而通常修饰名词的都是形容词，所以这个句子就类似形容词的作用。
状语从句非常多，很复杂，建议记着引导的关系词，然后看关系词后面是否是一个完整的句子，是的话它就是一个从句。
时间：when, as, while，whenever,every time,each time，since，before，till,until，as soon as,immediately,directly,once,the minute/moment (that) ，no sooner...than,hardly(scarcely)...when。。。。
地点：where(在..地方),wherever(无论哪里，在任何地方),everywhere(每一...地方，到处),anywhere（任何地方）
原因状语从句的连词有:because,as,since,for,now that,seeing that,considering (that),in that等
引导条件状语从句的连词或词组:if（如果）,unless（除非）,as(so) long as（只要）,on condition that(条件是...),provided/providing that（假如）,suppose/supposing（假如）,in case（如果）,for fear(that/lest)(惟恐;以免),only if(只要;只有),if only(但愿;要是...该多好)等。
让步状语从句的连词或词组有:although虽然，though虽然，even if/though即使;纵然;尽管，as尽管，while尽管，whoever(no matter who)不管谁，whatever(no matter what)无论什么，whenever(no matter when)无论什么时候，wherever(no matter where)无论哪里，however(no matter how)无论怎样，whether..or不论...还是。
引导目的状语从句的连词或词组一般有:so that以便，in order that以便，in case免得;以防，for fear(that)惟恐;以免，lest惟恐;以免;为不使。
结果状语从句一般由so,that,so that,so...that,such that等引导放在主句之后。
方式状语从句一般由连词as(正如;就像),as if/though(好像;宛如)引导。
比较状语从句一般由than（比）,as...as(和...一样),not as/so...as...(和...不一样),the+形容词比较级/副词比较级+the+形容词比较级/副词比较级(越...越...)等引导。
从句判断：
Spanning Los Angeles river , the sunny nook footbridge connects Atwater with Griffith park.后面这个句子是主句，前面这个句子是插入成分，它不是一个完整的句子所以不是从句。
Lying on the ice , I would soon die. I struggled to my feet knowing 【that somehow I had to put my tent up for shelter】.括号内的这个句子就是一个从句，有主谓宾。
判断从句就是先看它是否是两个不同的完整的句子，主要是看是否出现谓语动词，判断谓语动词这个是另外一个内容了。一个句子有两个谓语动词就是有一个从句和一个主句。或者可以直接按关系词得出这个句子的类型。
19.1 地点状语从句
地点状语从句通常由where, wherever 引导.
Where I live there are plenty of trees.
我住的地方树很多.
Wherever I am I will be thinking of you.
不管我在哪里我都会想到你.
19.2 方式状语从句
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 by.
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 man.
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 minds.
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 existed.
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 lighting.
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 soon.
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 time.
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 something.
他清了清嗓子,像要说什么似的.
The waves dashed on the rocks as if in anger.
波涛冲击着岩石,好像很愤怒.
19.3 原因状语从句
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 afraid.
Since /As the weather is so bad, we have to delay our journey.
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 ill.
He must be ill, for he is absent today.
19.4 目的状语从句
表示目的状语的从句可以由that, so that, in order that, lest, for fear that, in case等词引导,例如：
You must speak louder so that /in order that you can be heard by all.
He wrote the name down for fear that(lest) he should forget it.
Better take more clothes in case the weather is cold.
19.5 结果状语从句
结果状语从句常由so… that 或 such…that引导,掌握这两个句型,首先要了解so 和 such与其后的词的搭配规律.
比较：so和 such
其规律由so与such的不同词性决定.such 是形容词,修饰名词或名词词组,so 是副词,只能修饰形容词或副词. so 还可与表示数量的形容词many, few, much, little连用,形成固定搭配.
so foolish such a fool
so nice a flower such a nice flower
so many / few flowers such nice flowers
so much / little money. such rapid progress
so many people such a lot of people
（ so many 已成固定搭配,a lot of 虽相当于 many,但 a lot of 为名词性的,只能用such搭配.）
so…that与such…that之间的转换既为 so与such之间的转换.
The boy is so young that he can't go to school.
He is such a young boy that he can't go to school
19.6 条件状语从句
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 not.
Let's go out for a walk unless you are too tired.
If you are not too tied, let's go out for a walk.
典型例题
You will be late ___ you leave immediately.
A. unless B. until C. if D. 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 late. B、D句意不对,or表转折,句子如为 You leave immediately or you will be late.
19.7 让步状语从句
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 field.
虽然在下雨,但他们仍在地里干活.
He is very old, but he still works very hard.
虽然他很老,但仍然努力地工作.
Though the sore be healed, yet a scar may remain.
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 lot.
A. When B. However C. Although D. 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 do.
= Though he was a small child, he knew what was the right thing to do.
注意： a. 句首名词不能带任何冠词.
b. 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 satisfactorily.
= 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 though. 即使
We'll make a trip even though the weather is bad.
4) whether…or- 不管……都
Whether you believe it or not, it is true.
5) "no matter +疑问词" 或"疑问词+后缀ever"
No matter what happened, he would not mind.
Whatever happened, he would not mind.
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 now.
（对）Whatever you say is of no use now.
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 given. 囚犯们只能给什么吃什么.
状语从句一般是说明句子描述的时间，结果，让步逻辑，条件等
如：I'll call him as soon as he comes back.
She's so beautiful that I can't focus on my job.
However you try, you can't get it done.
I'll tell no one about our little secret if you do the same.
定语从句是细节说明句中的名词性成分，起修饰，详述的作用
The book, which is black in color, is written by a famous actress.
The cake (that) I made tastes bitter
名词性从句包括主语从句，宾语从句，表语从句和同位语从句
What doesn't kill you makes you stronger.
I don't know what you're talking about.
I am still who I've always been.
The idea suddenly crossed my mind that maybe I should try another line to reach him.
有两个或以上的分句构成的句子叫并列句或从句。
并列句由and,but,or等引导，表示并列，递进，转折等关系He
came
in
and
sat
down.
He
agreed
with
her,but
he
didn't
respect
her.Study
hard
,
or
you
will
not
pass
the
exam.
所有的从句中有连词的部分就是从句，没有连词的分句就是主句。
状语从句由when,where,because,so
that
,though等连词引导，表示时间地点原因结果让步等。When
I
came
in（从句）,
he
was
cooking（主句）.
Where
there
is
a
will（从句）,
there
is
a
way（主句）
.
He
was
late（主句）
because
he
got
up
late（从句）,
.
名词性从句分为主语从句，宾语从句表语从句，同位语从句。句子中主语的位置应该是名词或代词，如果这部分是一句话就是主语从句。比如
It
was
right.
是简单句
It是主语,
What
he
said
was
right.就是主语从句.
同样,It
was
right中right是表语,
It
was
what
he
said
就是表语从句，宾语从句，同位语从句，定语以此类推。
句中的动词前的发出动作者是主语，位于动词后动作的承受者就是宾语。I
love
her.
love是动词，前面的I
就是主语，后面的her就是宾语。
主句从句都是一个道理
单永罗浮： 1.名词能做的基本成分,变为句子,简单的理解为名词性的从句.比如:名词作主语,变为句子,就可以理解为(主语从句),名词宾语,表语也一样理解(另外还要记住一个:同位语从句属于名词性从句) 2.定语从句时由形容词的性质决定的,(修饰名词,代词)因此,我们可以说:形容词性的从句: 既:定语从句(修饰性质)另外还有修饰整句句子等(非限制性定从). 3.状语从句(由副词来担任)也是修饰性从句,主要是修饰动词,,一般地说:有8种情况,也有 解释为:九种.

When I was 6, my mother left me.就是时间状语从句.
