1．主语从句
在复合句中充当主语的从句叫主语从句。
That you didn't know the rules won't be an excuse for your failure.
你不知道规则不能成为你失败的借口。
Whether we should help up a fallen old person or not remains a heated topic in China.
我们是否应该帮忙扶起一个摔倒的老人在中国仍然是一个热门话题。
When the delayed flight will take off depends much on the weather.
那架延误的班机什么时候起飞在很大程度上取决于天气。
1．主语从句
[名师指津]　有时为避免句子头重脚轻，常用it代替主语从句作形式主语放于句首，而把主语从句置于句末。主语从句后的谓语动词一般用单数形式。常用句型如下：
(1)It＋be ＋名词＋that从句
(2)It＋be ＋形容词＋that从句
(3)It＋be＋动词的过去分词＋that从句
(4)It＋不及物动词＋that 从句
It is clear that the two countries can reach an agreement at the conference.
很显然两国能够在会议上达成协议。
It is well known that the Chinese government has spared no effort to protect people from fake food.
众所周知，中国政府已不遗余力地保护人们免受假冒食品的毒害。
2．宾语从句
在复合句中充当宾语的从句叫宾语从句，位于及物动词(短语)、介词或形容词之后。
We must never think (that) we are good in everything while others are good in nothing.
我们决不能认为自己什么都好，别人什么都不好。
Everything depends on whether we have enough money.
一切要看我们是否有足够的钱。
She will give whoever needs help a warm support.
凡需要帮助的人，她都会给予热情的支持。
2．宾语从句
[名师指津]　在可以接复合宾语的动词之后，如think，make，consider等，可以用it作形式宾语。
He has made it clear that he will not give in.
他不会屈服的，这一点他已明确表示了。
3．表语从句
在复合句中充当表语的从句叫表语从句。引导表语从句的关联词与引导主语从句的关联词大致一样，表语从句位于连系动词后，有时用as if，because等引导。其基本结构为：主语＋系动词＋从句。
The fact is that we have lost the game.
事实是我们已经输了这场比赛。
That is why he didn't come to the meeting.
那就是他为什么不到会的原因。
It looks as if it is going to rain.
看上去天要下雨了。
3．表语从句
[名师指津] 当主语是reason时，表语从句要用that引导而不是because。
The reason why he was late was that he missed the train by one minute this morning.
他迟到的原因是，今天早晨他晚了一分钟而错过了火车。
4．同位语从句
同位语从句说明其前面的名词的具体内容。同位语从句通常由that引导，也可由其他连接代词或连接副词引导，可用于同位语从句的名词有：advice，demand，doubt，fact，hope，idea，information，message，news，order，problem，promise，question，request，suggestion，truth，wish，word等。
The news that we won the game excited all of us.
我们赢得这场比赛的消息让我们每个人都很激动。
I have no idea when he will come back home.
我不知道他什么时候回家。
4．同位语从句
[名师指津]　同位语从句和定语从句的区别：
(1)意义不同：同位语从句是跟在一个抽象名词之后，对该名词的具体内容作进一步解释说明；而定语从句在复合句中作定语，对前面名词进行修饰、限制。
(2)连接词用法不同：that作为关系代词，可以引导定语从句，充当句子成分，在从句中作宾语时可以省略； that引导同位语从句时，只起连词的作用，没有实际意义，不充当句子成分，一般不能省略。

This winter vacation I went to Dunhuang to explore the Silk Road with my classmates.
When we got off the train，we were all excited and attracted by which we saw. The next day，we visit the Mogao Caves. Impressing by the great construction，we took many photos. A guide introduced the wall paintings to me. With curiosity，we listened attentive，asking questions and taking note. The camel ride on the third day was the most excited part of our tour. Looking far into the desert，I pictured that how ancient Chinese travelled along the long route. Before leaving，we took a group photo and to memorize the tour along the Road.
