同位语、表语、宾语、定语,状语从句分类.ppt

从句分类;名词性从句（包括主语从句，宾语从句，表语从句，同位语从句） ;形容词性从句（即定语从句） ;副词性从句（即状语从句,包括时间、条件、结果、目的、原因、让步、地点、方式等） ;If he comes tomorrow, you will see him. 如果他明天来，你就可以看见他。（if 引导的条件状语从句，其结构为：if +状语从句，＋主句）。要注意在状语从句中有一个规则是“主将从现”，即主句是将来时，则从句要用一般现在时表示将来。  He returned home to learn his daughter had just been engaged.他回家后得知女儿刚刚订婚了。（结果状语，结果状语只是仅限于learn（得知），find（发现），see，hear，to be told（被告知），make（使得）等具有界限含义的动词。）  You must speak louder so that /in order that you can be heard by all. 你必须大声说话，才能让所有人听到你说话。（目的状语，可以由that, so that, in order that, lest, for fear that, in case等词引导。）;Since /As the weather is so bad, we have to delay our journey. 天气那么糟，旅行就推迟了。 （原因状语从句，常用 because, since, as, for fear ( 恐怕 ), seeing that ( 既然 ) ， now that (=since), considering that ( 考虑到 ) 等引导。） Though/Though he was worn out, (still) he kept on working. 虽然他已经精疲力竭了，但仍然继续工作。 （让步状语从句，引导的连词主要有以下这些：though, although, as; even if, even though; whether...or...; no matter+疑问词，疑问词-ever.) Where I live there are plenty of trees. 我住的地方树很多。（地点状语从句，通常由where, wherever 引导。） As water is to fish, so air is to man. 我们离不开空气，犹如鱼儿离不开水。（方式状语从句通常由as, (just) as…so…, as if, as though引导。）;1、由从属连词that, whether 引导的主语从句。;2.由连接代词who, whose, which, what引导的主语从句.;4、为了保持句子结构平衡,有时it作形式主语,而将主语从句放到谓语部分后.

It is still a question whether she will come or not. It is not known when he went. It is no business of yours where I spend my summer holidays. It is not clear why he did it.;;Notice： 1、引导主语从句的that在从句中起到结构的作用，在句意中没有意义，但不可省略。;That education plays a vital role in all walks of life is clear.
