一、成分
主语、宾语、表语、同位语
   
主语:The movie proves brilliant.
宾语:I appreciate the actress.
表语:She keeps a ghost.
同位语:I enjoy the part, the end.
(同位语只能跟在名词后,the part=the end;作文中任何名词的后面都可以再加一个名词作为同位语出现)
例句:Over fishing, a universal phenomenon throughout the word, has become increasingly grave under modern conditions.
过度捕捞,一个全球普遍现象,已经变得越来越严重了。
二、什么是名词性从句
主语从句:
The movie proves brilliant.
What I saw proves brilliant.
宾语从句:
I appreciate the actress.
I appreciate what she did.
表语从句:
She keeps a ghost.
She keeps who I admire.
同位语从句:
I enjoy the part, the end.
I enjoy the part that she knew the truth.
名词在句子中能够充当的成分从句都能充当这就是名词性从句,名词性从句一共包括四类:主语从句、宾语从句、表语从句、同位语从句
三、名词性从句的引导词
例句
她已经离婚了是显而易见的
sort of英文She has got divorced is conspicuous.(句子不能做主语)
That she has got divorced is conspicuous.
她离婚了吗是个秘密
Has she got divorced keeps a secret.→
whether she has got divorced keeps a secret.
她什么时候离婚是个谜
When did she get divorced remains a mystery. →
When she got divorced remains a mystery.
引导词
名词性从句的引导词是按照从句的类型分的类,一共把引导词分成三类:
that(当从句是陈述句时,并且that在从句中不充当任何成分也没有任何意思)
whether(当从句是一般疑问句时,并且whether在从句中不充当任何成分,意思翻译成是否)
所有特殊疑问词(当从句是特殊疑问句时)
并且英语中所有的从句一定都是陈述句的形式,也就是引导词+主语+谓语的形式
练习:
练习一:
我正在思考外星人存在吗
I am wondering whether the allien exists.(宾语从句)
(可数名词不能单独使用,a/复数/the;不确定是否可数用the)
练习二:
他们为什么去西藏离开家乡是一个谜
Why they left hometown for Tibet remains a mystery.(可数名词不能单独使用)
Why they left their hometown for Tibet remains a mystery.(主语从句)
(主系表)
练习三:
关键是你什么时候有钱呀
关键(主语)是(谓语)你什么时候有钱呀(表语)
The point seem when wealth will be available for you.(表语从句)
available可得到的
练习四:
有一天你会发现事业、友情、亲情都比爱情重要
你(主语)发现(谓语)事业、友情、亲情都比爱情重要(宾语)
Someday, you will find that career, kinship and friendship are all more indispensable than romance.(宾语从句)
四、分析
(一)写作分析
1.主语从句
主语从句的满分表达就是把主句从句放到句末去,加it做形式主语,主语从句的满分句型可以写在作文中任何一句话的前面用来拉长句子
显而易见,众所周知:
It keeps common knowledge that
It looks beyond dispute that(超越争论)
It is universally acknowledged that
It has been widely accepted that
我认为:
It keeps my perspective that
例句:女人总是对的是一个常识
That ladies tend to be right keeps  common knowledge. 
→It keeps  common knowledge that ladies tend to be right. 
例句:关于养宠物这个话题已经引起广泛关注了
It has been widely accepted that the subject about raising pets has been brought into the limelight. 
2.同位语从句
同位语从句的位置:名词后;句末
她的丈夫去世了这个消息传遍了整个村庄
The news that her husband passed away has been spread the whole village.
→(The news  has been spread the whole village that her husband passed away.同位语从
句可以放在句末,但作文中不要放在句末)
河南人都是骗子这个想法是不正确的
The outlook that individuals from henan province tend to be deceivers remains wrong.
(outlook/perspective/idea观点,看法)
温室里的花朵不能经受风雨这个事实表明我们不应该溺爱孩子
The evidence that flowers in the greenhouse fail to endure storms demonstrates that kids should never be spoiled.
