that引导的主语从句用法详解：
1、that在句中不做成分。当主语从句位于句首时，不能省略。
2、在形式主语it引导的主语从句结构“It is+形容词/名词/名词短语等+that主语从句”中。
如果is后面的表语是表示重要或必要等(如important、necessary、a necessity等)含义时，that从句中的谓语动词一般要采用“should+do”的虚拟语气形式，should经常省略。如：
It is imperative that we (should) make a quick decision. 我们要尽快做出决定。
It is necessary that we (should) learn English well. 我们必须学好英语。
英语的主语从句宾语从句表语从句
主语从句就是一个从句，它做另一个句子的主语。
主语从句在复合句中作句子的主语。引导主语从句的词有连词that, whether; 连接代词who, what, which; 连接副词when, where, how, why等。如：
What is needed for the space trip is careful preparation.
Whether wild life can be well protected is of great importance.
Who will go makes no difference.
Why dinosaurs died out remains a puzzle.
Which kind of food is the best is still not certain.
为了避免主语显得过长，可以用it作为句子的主语，把主语从句移到句子的末尾。如：
It hasn’t been decided yet when the new restaurant will open.
It is not clear how gold was found there.
It is hard to understand why there is gravity.
It is a shame that you have to leave so soon.
宾语从句（The Object Clause）
宾语从句在复合句中作主句的宾语。宾语从句通常由下面一些词引导。
（1） 由that引导（that在口语或非正式文体中常省略）。如：
I don’t think (that) differences are important in a friendship.
Some readers said (that) they are going to eat more vegetables.
An old lady said (that) she found a job as a foreign language teacher.
I think (that) women can reach very high achievements in many fields of science.
(2)由连接代词或连接副词引导。如：

主语从句与宾语从句两者的用法和在句中的作用是不同的，下面从它们的各自用法，介绍：）
一．主语从句
主语从句 定义:在句子中担当主语的是一个从句,这个从句就叫做主语从句。
主语从句是在复合句中充当主语的从句，通常放在主句谓语动词之前或由形式主语it代替，而本身放在句子末尾。
1. It 作形式主语和it引导强调句的比较
It 作形式主语代替主语从句，主要是为了平衡句子结构，主语从句的连接词没有变化。而it引导的强调句则是对句子某一部分进行强调，无论强调的是什么成分，都可用连词that。被强调部分指人是也可用who/whom。例如：
It is a pity that you didn’t go to see the film.
2. 用it 作形式主语的结构
(1) It is ＋名词＋从句
It is a fact that … 事实是…
It is an honor that …非常荣幸
It is common knowledge that …是常识
(2) it is ＋形容词＋从句
It is natural that… 很自然…
It is strange that… 奇怪的是…
(3) it is ＋不及物动词＋从句
It seems that… 似乎…
It happened that… 碰巧…
(4) it ＋过去分词＋从句
It is reported that… 据报道…
It has been proved that… 已证实…
3. 主语从句不可位于句首的五种情况
(1) if 引导的主语从句不可居于复合句句首。
(2) It is said , (reported) …结构中的主语从句不可提前。例如：
It is said that President Jingo will visit our school next week.
(3) It happens…, It occurs… 结构中的主语从句不可提前。例如：
It occurred to him that he failed in the examination.
(4) It doesn’t matter how/whether …结构中的主语从句不可提前。例如：
It doesn’t matter whether he is wrong or not.
(5) 含主语从句的复合句是疑问句时，主语从句不可提前。例如：
Is it likely that it will rain in the evening?
4. What 与that 在引导主语从句时的区别
What 引导主语从句时在句时在从句中充当句子成分，如主语．宾语．表语，而that 则不然。例如：
What you said yesterday is right.
二：宾语从句的几个特征：1、引导词：what\which\whose\when\whether\if\where
2语序：宾语从句必须是用陈述语句。
如：I think that you must work harder.
宾语从句的引导词、连接词的区别、否定转移等现象。
(1)表达时间的几个句型：一般用when或者是what time：
What time will the train leave?
由于时刻都是固定的，也可以用一般现在时代替一般将来时：
What time does the train leave?
(2)时间的表达方式：8：19(nineteen past eight),7:57(three to eight)，在时间的中间也可以加上分的单词(minutes)
(3)had better +动词原型。意思是提要求，建议。但是上下级不能用这种方式，因为语气太重：
You had better give up smoking .
(4)sb leave sth +地点
I left my book in my classroom yesterday.
(5)may I have your name(address\age)?一般询问对方的年龄、名字等，不要习惯以前的问法，这样很不礼貌，而是要采访上面的问法。以前的习惯是：how old are you? \what's your name?
(6)修饰名词的代词次序：限-描-大-形-年-颜-籍-物-类+名词：
this is a bridge.
This is a beautiful bridge
补充：从句的语序永远是陈述句。
