有三大类 1.名词性从句 2.定语从句 3.状语从句 名词性从句中分： 1.主语从句：例,it is important to read book.(形主it作主语,真正的主语是to read book) that air has pressure was known long ago.(关联词that引导的句子that air has pressure作主语从句) 2.宾语从句：I think it necessary that he should do his homework.(形式宾语it引导的) I'm sure that my test will succeed.(sure后用that引导的宾从) 3.表语从句：系动词后的从句 it may be as you say(be是系动词,后面用as引导的) this is that he is too young to go to school.(有系动词is,后面由that引导的表语从句) 4.同位语从句：同位语从句是对前面名词的解释说明,如： The facts that he had done his homework.(事实就是he had done his homework,是对前面the facts的解释,是什么事实) 定语从句：在句子中起定语作用,修饰剧中的名词或代词的从句叫定从 例：the man (who is shaking hands with my father) is my teacher.(括号中就是定从,修饰限定the man) BeiJin is a city (which has a long history).(括号中是定从,修饰the city) 状语从句：在复合句中担任状语成分的从句叫状语从句 例：I will tell her about that (when i see her).为时间状从 just stay (where you are).为地点状语 Because he is ill,he is absent today.为原因状语 这也很局限,其实要讲的还很多,你可以多看看语法书之类的

4.同位语从句
同位语从句用于对前面出现的名词作进一步说明，一般用连词that引导，由于先行名词的意义不同，也可用whether,who,when,where,what,why,how等引导。常见的先行名词fact,idea,belief,news,hope,conclusion,evidence,suggestion,order,problem,report,decision.有时由于谓语较短，将同位语从句位于谓语之后。She finally made the decision that she would join the fashion show.I had no idea how many books I could borrow at a time.The news came that their team had won the championship.
5.定语从句定语从句所修饰的先行词可以是名词或代词，也可以是一个句子。定语从句通常位于先行词之后，由关系代词或关系副词引导。This is the computer on which he spent all his savingsIt is written by a person with whom we are all familiar.6.状语从句*时间状语从句As soon as I sent an e-mail message,I received positive responses.The moment he heard the good news,he jumped with joy.*地点状语从句Considering that he is a freshman,we must say he is doing well.Mickey Mouse is so attractive that the children are reluctant to leave.We got up early this morning so that we could catch the first bus to the railway station.*条件和让步状语从句As long as you have the right equipment,you can use a telephone line to transmit computer data.No matter what you may say,I would not change my mind.Young as he is,he is quite experienced in this work.(=though he is young)Child as he is,he can speak English fluently.(=though he is a child)*方式状语从句The young man made the experiment just as the teacher had taught him.Everything went on as usual as if nothing had happened.
