名词性从句详解及练习
各类从句详解英语从句可以分为名词性从句、定语从句和状语从句三大类：下面我们逐一进行说明：一、名词性从句（主语从句、表语从句、宾语从句、同位语从句）主语从句、表语从句、宾语从句和同位语从句在复合句中的充当的成分和其名称相同，分别作主句的主语、表语、宾语和同位语。
上述这四种从句均被称为名词性从句。
所有的名词性从句均不能用逗号分开，并且它们都用相同的关联词，关联词如下：①主从连词：that (无意义), whether (是否), if (是否)（在句子中不充当任何成分）②连接代词：who (谁), whom (谁), whose (谁的), what (什么), which (哪一个)③连接副词：when (什么时候), where (什么地方), how (怎样), why (为什么)主从连词只起连接作用，连接代词和连接副词除了起连接作用外，还充当从句某一个成分。
另外，可以用whatever, whichever, whoever, who(m)ever等连接代词引导名词性从句，来加强语气。
下面分别对各种名词性从句进行介绍（一）主语从句（subject clause）在主句中用作主语的主谓结构称之为主语从句。
例如：That he will come to the discussion is certain.他来参加讨论是确定的。
That the moon moves round the earth is well known to all of us.月球绕地球转动，这是我们大家都熟知的。
When the meeting is to be held has not yet been decide.会议什么时候召开还没有决定。
主语从句放在句首，句子常常显得比较笨重，因此通常可以把it放在句首，作形式主语，而将主语从句放在后面。
例如上面的句子可以分别改写为：It is certain that he will come to the discussion.It is well known to all of us that the moon moves round the earth.It has not yet been decide when the meeting is to be held.下面再举一些例句：What they are after is profit.他们追求的是利润。
从句历年真题及解析
一、名词性从句名词性从句主要分为四大类：主语从句、宾语从句、表语从句和同位语从句。
<一>主语从句1. that引导的主语从句that引导的主语从句既可以放在句首也可以放在句末，在实际应用中我们常常采用it形式主语的形式。
例句：That he passed the English test is true. 千真万确，他通过了英语考试。
→It is true that he passed the English test.2. 形式主语的四个主要句型（1）It + be + 名词+ that从句例：It is a pity that … 可惜的是可应用于此句型的名词还有fact / shame / honor / question等。
（2）It + be + 形容词+ that从句例：It is certain that … 很肯定可应用于此句型的形容词还有clear / better / natural / important 等。
（3）It + be + 动词的过去分词+ that从句例：It is said that … 据说可应用于此句型的过去分词还有believed / known / reported等。
（4）It + 不及物动词+ that 从句例：It seems that … 好像是可应用于此句型的不及物动词还有happen / appear 等。
3. wh- 引导的主语从句例句：Where we will go hasn’t been decided. 我们要去哪儿还没定下来。
<二>宾语从句1. that引导的宾语从句that常用来引导宾语从句，通常that可以省略。
例句：He has told me that he will go to Shanghai tomorrow.他已经告诉我他明天要去上海。
注意：在demand、order、suggest、decide等表示要求、命令、建议、决定等意义的动词后，that从句常用“（should）+ 动词原形”的结构。
虚拟语气在在同位语从句和表语从句中的应用例题
虚拟语气在同位语从句和表语从句中的应用比较少见，但仍然存在一些例子。
以下是一些虚拟语气在同位语从句和表语从句中的应用例题：同位语从句：他提出的建议，即我们应该立即采取行动，是非常明智的。
The suggestion he put forward, that we should take immediate action, is very wise.他们没有意识到他们面临的危险，这是一个严重的错误。
The fact that they didn't realize the danger they were in was a serious mistake.在以上两个例子中，虚拟语气用于同位语从句中，用来表示建议、要求、命令等。
在第一个例子中，“that we should take immediate action”是虚拟语气，表示建议。
在第二个例子中，“that they didn't realize the danger they were in”是虚拟语气，表示事实与他们的想法相反。
表语从句：他的建议是我们应该立即采取行动。
His suggestion is that we should take immediate action.问题是我们没有足够的时间来完成这个任务。
The problem is that we don't have enough time to finish this task.在以上两个例子中，虚拟语气用于表语从句中，用来表示建议、要求、命令等。
在第一个例子中，“that we should take immediate action”是虚拟语气，表示建议。
在第二个例子中，“that we don't have enough time to finish th is task”是虚拟语气，表示事实与问题相反。
需要注意的是，虚拟语气在同位语从句和表语从句中的应用相对较少，通常用于正式的书面语中。

高中英语名词性从句知识点含练习
高中英语名词性从句知识点（含练习）基础回顾1.表语：表语用来说明主语的身份、性质、品性、特征和状态的，表语常由名词、形容词、副词、介词短语、动词的-ing、不定式、从句来充当，它常位于系动词(be, become, appear, seem,look,sound,feel,get,smell等词)之后。
如：Her job is selling computers. 此句表语为selling computers如果句子的表语也是由一个句子充当的，那么这个充当表语的句子就叫做表语从句。
2.同位语：一个名词(或其它形式)对另一个名词或代词进行解释或补充说明，这个名词(或其它形式)就是同位语。
如Mr. Smith,our new teacher,is very kind to us. 我们的新老师史密斯先生对我们很好。
Mr.Smith是主语our new teacher的同位语，指同一人。
同位语从句I heard the news that our team had won．我听到了我们队获胜的消息。
that our team had won 解释news的具体内容，是同位语正文一、定义在复合句中具有名词的性质的作主语、表语、同位语、宾语的从句叫名词性从句。

That he finished writing the composition in such a short time surprised us all他在很短的时间内写完作文让我们都很惊讶 (主语从句)The trouble is that she has lost his address. 麻烦的是她把他的地址搞丢了。
（表语从句）They have no idea at all where he has gone. 他们不知道他去什么地方了。
