怎么区分状语从句与名词性从句定语从句
名词性从句所充当的成分都可由名词充当,例:主语从句,宾语从句,表语从句,同位语从句,一般由what,which,who,whom,whose,how,why,where,when,whether,if(是否),that(一般省略)引导,除同位语从句外的名词性从句如果直接去掉则句子不完整,读起来也不通顺。
状语从句一般分为九种:原因,结果,比较,方式,让步,地点,时间,条件,目的。但连接词非常没有规矩,且一般不用上述的名词性从句的引导词。在句子中将状语从句直接去掉,句子仍然完整(主,谓,宾(表))
谢谢

英语中的名词性从句有哪些
1、
名词性从句是指在句子中相当于名词的从句,主要包括主语从句、宾语从句、表语从句和同位语从句。名词性从句不是修饰性从句,而是复合句中的主干。
e.g. That the boy failed again in the exam disappointed his mother. (主语从句) I know that he is writing his composition in his room. (宾语从句)
The question is how we can finish it on time. (表语从句)
The fact that some Chinese are still poor is really a great problem. (同位语从句)
2、在复合句中 , 修饰名词或代词的从句叫定语从句 , 被修饰的名词或代词叫先行词 , 引导定语从句的有关系代词 who, whom, whose, which, that等和关系副词where, when, why等 , 关系代词和关系副词在定语从句中担任句子成份。
1.由who引导的定语从句中 , who用作主语 , 如 : This is the boy who often helps me. 2.由whom引导的定语从句中,whom用作宾语,如:The man whom you are waiting for has gone home.
3.由whose引导的定语从句中 , whose用作定语 , 如 : Do you know the girl whose skirt is white?
4.由which引导的定语从句中,which用作主语或谓语动词的宾语或介词的宾语,如: The room in which there is a machine is a work shop. The river which is in front of my house is very clean. This is the pen which you want.
3、状语从句即指在主从复合句用作状语的从句。按照其意义,状语从句可分为时间状语从句、地点状语从句、原因状语从句、目的状语从句、结果状语从句、条件状语从句、让步状语从句等。
时间状语从句
一般来说,时间状语从句常由连词when, before, after, as soon as或until引导。在使用时,从句一般不用一般将来时态。若主句为一般将来时态或是含有将来的意味时,时间状语从句常用一般现在时态来代替将来,即“主将从现”。如:
I will go to the cinema as soon as I finish my homework. 我一完成作业就去电影院。
When I grow up, I will join the army. 当我毕业了,我就要去参军。
条件状语从句
条件状语从句常由if(如果)、unless(除非)或as long as(只要)来引导,同样适用于“主将从现”。如:
We will stay at home if it rains tomorrow. 如果明天下雨了,我们就会呆在家。
He won’t come here unless he is invited. 除非被邀请,否则他不会到这儿来的。
As long as you give me money, I will go with you. 只要你给我钱,我就跟你走。
原因状语从句
原因状语从句常由because(因为),since(既然;由于)或as(由于)来引导。在使用时,注意because和so(所以)不能用在同一个句子中。如:
Since you can’t help me, I’ll find someone else. 既然你帮不了我,那我就找其他人吧。
He failed the exam because he didn’t work hard.
= He didn’t work hard, so he failed the exam. 因为他不努力,所以考试没有及格。
让步状语从句
让步状语从句由although或though(虽然;尽管)来引导。注意,在使用时,though或although不能和but不能用在同一个句子中,两者只能用其一。如:
We still worked in the field although / though it was raining hard.
= It was raining hard, but we still worked in the field.
尽管天下着大雨,但是我们仍然在地里干活。
什么是名词性从句
名词性从句就是从句起着名词的作用,那么名词放哪,它就可以放哪,比如,名词可以做主语,那就放主语位置:You who is a good student study well. 名词可做宾语,可以放宾语位置:I like English which I think is very useful.在复合句中,由从句表示的状语叫做状语从句。它可以用来修饰主语中的动词.形容词.副词等。根据它表达的意思,状语从句可以分为时间状语从句.
状语从句,条件状语从句,比较状语从句,目的状语从句,结果状语从句和让步状语从句等。由连接词if引导的状语从句叫做条件状语从句。(注意:在含有条件状语从句的复合句中,如果主句是一般将来时态,从句要用一般现在时[主将从现原则])
语法
经典语句:If it dosen't rain tomorrow,we shall go to the zoo.
If you open the door,I shallcome in.
条件状语从句就是用以表示“在某种条件下,会……”
常用if ,in case , on condition whether等词来引导
连接词主要有 if, unless, as/so long as, on condition that,provided,suppose,supposing 等。.
主句用一般将来时,if或unless引导的条件状语从句用一般现在时。
固定搭配:unless = if...not.
e.g. Let's go out for a walk unless you are too tired.
If you are not too tired, let's go out for a walk.
if 引导的条件句有真实条件句和非真实条件句两种:
真实条件句,
如:If it rains tomorrow, we shalln’t go on a picnic.
非真实条件句是虚拟语气的一种,表示与事实相反,如:
If I were you, I would go with him.
if wrless,on condition that
so/as long as只要
由as (so) long as, in case引导。
So long as you’re happy, it doesn’t matter what you do.
只要你高兴,你做什么都没有关系。
You may borrow my book as long as you keep it clean.
只要你保持书的清洁,你就可以把我的书借去。
Take your umbrella in case it rains.
带着你的伞吧,以防下雨。
