英语中的名词性从句、定语从句、状语从句指的是哪些啊?

当英语基础知识的学习进入一个相对稳定的时期,就应该逐渐地接触和了解英语中的主从复合句,以期通过一个主从复合句来表达更加复杂的含义,并传达更多的信息.因为语序以及时态问题,中英文在主从复合句方面有着天壤之别,自然就造成了中国学生在学习英语主从复合句时出现迷惘和困惑.莱曼英语在对待英语主从复合句方面,更加强调由浅入深地有条理地系统学习.
一.主从复合句的分类：
英语中的主从复合句从功能上可分为下列几种类型：
1.主语从句
2.宾语从句 （1）时间
3.表语从句 （2）地点
4.状语从句----------（3）原因
5.定语从句 （4）条件
（5）目的
（6）结果
（7）让步
（8）方式
（9）比较
作为学生,完全没有必要死记硬背主从复合句的种类,而是更加着眼于英语主从复合句的特点和使用要点.这也是对主从复合句考核的重要内容.
二.主从复合句的要点：
1.连词（主从复合句的连接词）的选用
A类： that
B类： if,whether
C类： what,when,where,who.why,whose,which
how,whom
D类：since,as,while,before,after,till,until
once,whenever,wherever,because,unless
though,although,
E类：as soon as, as long as, so long as,
in case, so that, in order that,
so...that, such...that, as if,
each time,next time,
the first time,the last time
by the time, from the time.
2.时态前后呼应
A:主句是现在时,从句任意
(1)He always helps me with my English when he has time.
(2)She always says that she had a tough life in the past.
(3)Nobody knows what he will do in the future.
（4)The boys are talking about the football game which was shown on TV yesterday.
(5)The students are talking while the teacher is speaking in the class.
B:主句是过去时态,从句必须是过去时态
(1)He told me on the phone that he was driving on the highway.
(2)They wanted to know whether they had passed the exam.
(3)Students were discussing what they would do in the future.
(4)I wondered where the boy came from.
(5)We were cleaning the room while he was playing the video game.
3.从句永远用陈述语序
特别是当连词为特殊疑问词时,此时,必须明了的是,从句并非特殊疑问句.因而,从句不得用问句形式,而必须用陈述语序.
(1)I asked him what he was doing there.
(2)They wanted to know where I had been.
(3)The teacher wondered why he was late for class.
(4)He told us whom the house belonged to.
(5)I felt surprised how he made it.
4.主句是现在将来时,从句用一般现在时（主将从现）
英语的主从复合句中,主句为现在将来时,从句则必须是一般现在时,此时的从句多作为一种先决条件,表明无论是现在还是将来,只要条件满足,则主句的动作就将发生.
(1)We will have a meeting as soon as he comes back.
(2)We will have an outing if it doesn't rain tomorrow.
(3)They are going to have a football game with Class 3 when they are free.
(4)Nobody will help him if he keeps cheating.
(5)She will buy some clothes as long as she has money.

多出现在宾语从句中,条件是：
（1)连词为特殊疑问词或if,whether
(2)从句含有情态动词或将来时
