复合句
Complex Sentence
   由一个独立的句子和一个或一个以上非独立的句子组成的句子称为复合句。主句是句子的主体部分，从句只作句子的一个从属部分，不能独立成句。复合句常由连词将从句和主句联系在一起。从句在主句中作什么成分就叫什么从句，例如从句作宾语就叫宾语从句。从句包括主语从句、表语从句、宾语从句、同位语从句、定语从句和状语从句。
1. 主语从句
   主语从句在复合句中作主语，它的作用相当于名词。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。例如：
That I was right is clear.  我是对的，这很清楚。
Whether he'll come or not has not been decided yet.  他是否来还没有决定。
Who is coming to the party is unknown.   谁来参加聚会，还不知道。
What he said is not true.   他所说的不是真的。
Which team has won the game is not known.   哪个队赢了比赛，还不知道。
When we will have the discussion depends on the teacher.   我们什么时候讨论将取决于老师。
Where we will meet will be decided by you.   我们什么时候见面将由你来决定。
How she got the prize is still a secret.   她怎样得到的那个奖还仍然是个秘密。
Why Tom was late remains a puzzle.  汤姆为什么迟到还是个谜。
2. 表语从句
   表语从句在复合句中作表语，它的作用相当于名词。引导表语从句的词有连词that, whether, as if; 连接代词who, what, which; 连接副词when, where, how, why等。例如：
The fact is that we're behind the others.  事实是我们已经落后于别人。
The question is whether it is worth reading.  问题是它是否值得一读。

3. 宾语从句
宾语从句在复合句中作及物动词或介词的宾语，常由下列一些连词引导。
   由连词that引导。that在从句中不充当任何句子成分，只起连接主句和从句的作用，在口语和非正式文体中可省略。例如：
She said (that) she would return the book soon.   她说她很快就会还书。
He said (that) he would come here and (that) I should wait for him.  他说他会来这儿，并让我等他。
   由连词whether或if引导。whether或if在从句中不充当任何句子成分，只是起连接作用，但不能省略。它们的意思都是“是否”，在把句子翻译成汉语时需要译出来。例如：
I wonder whether/if he'll agree with me.   我不知道他是否同意我的意见。
I don't know whether/if he will come back this evening.   我不知道他今晚是否会来。
   由连接代词who, whom, whose, which, what或连接副词when, where, how, why引导。连接代词或连接副词位于从句的前面，起连接主句和从句的作用。从句用陈述句语序。它们在从句中充当一个成分，并保留原有的疑问含义，把句子译成汉语时需要译出。例如：
I can guess who/whom you have talked with.   我可以猜出谁和你谈话了。
I know whose brother he is.  我知道他是谁的兄弟。
Do you know which team lost in the game?  你知道哪个队在比赛中输了吗？
Tell me what you have done.  告诉我你干了什么。
We have to decide when we'll set off.   我们必须决定什么时候动身。

I wonder how he got so much money.  我想知道他是怎么搞到那么多钱的。
I can not understand why he said that again.   我不明白他为什么又说那个了。
4. 定语从句
   在复合句中，修饰某一名词或代词的从句叫作定语从句。定语从句需要放在所修饰词（先行词）的后面。引导定语从句的连词有关系代词who, whom, whose, which, that和关系副词when, where, why等。例如：
Do you know the man who is singing now?  你认识那个正在唱歌的人吗？
He is the man (whom/that) the teacher blamed.  他就是那个被老师责备的人。

  【注意】：后两句为非限制性定语从句，是先行词的附加说明，如果省去，也不影响主句的意思，它和主句之间用逗号分开，并且不能用that作连接词。  
5. 同位语从句
   同位语从句一般是跟在某些抽象名词（如news, fact, belief, idea, suggestion, advice等）后面的由连词that引导的从句。与定语从句不同的是：同位语从句只是进一步阐述或说明所修饰的词的详细内容，并且只能用that作连接词。例如：
Everyone knows the fact that it is colder in winter than in summer here.   每个人都知道这个事实：这里的冬天比夏天冷。
His suggestion that we hold the meeting next week cannot be accepted.   他有关下周开会的建议不能被接受。   
6. 状语从句
复合句中起状语作用的从句叫作状语从句。状语从句可以用来表示时间、地点、原因、结果、目的、条件、比较、方式、让步等。
时间状语从句常用when, as, while, after, before, as soon as, until等连词引导。例如：
