主从复合句表语从句在句子中作连系动词的表语的从句,它位于主句中的系动词之后。

例如:.t.schoo.yesterday..I.i.becaus.yo.ar.s.clever. 宾语从句在句子中作及物动词或介词的宾语。

①基本形式: （主句+）连词+从句主语+从句谓语+...②关于宾语从句连词的选择:若从句来源于一个陈述句,那么,连词用that,在口语中that可以省略;若从句来源于一个一般疑问句,连词则用if 或whether;若从句来源于一个特殊疑问句,则连词就是疑问词(如what,who,where,when等)例如:pute.wil.finall.tak.th.plac.o.huma.beings.(他们相信计算机终将代替人类。

.(从句本来就是陈述句)..wonde.whethe..shoul.sa.somethin.fo.hi.t.th.headmaster.(我不知道是不是该为他在校长跟前说点什么。

.(从句来源于一般问句Shal..sa.somethin.fo.hi.t.th.headmaster?..H.aske.m.wher.h.coul.ge.suc .medicine.(他问我在哪儿能搞到那样的药。

.(从句来源于特殊问句Wher.ca.h.ge.suc.medicine.)③宾语从句的时态问题: 如果主句是现在时,从句则用现在某一时态,甚至可以用过去时；如主句是过去时,从句则相应地使用过去某一时态,遇到客观真理时仍然用现在时。

如：.thin..wil.d.bette.i.Englis.thi.term.(我想本学期我的英语会学得好点。

..Th.teache.aske.th.bo.i.th.eart.i.round.(老师问那个男孩地球是不是圆的。

)④下列结构后面的从句一般也作为宾语从句看待:b.sorr..afrai..sur..gla.+that从句,如：I’.sorr.I’.late.(对不起,我迟到了。

一…… 就……
结果状 so that
结果
语从句 so/such...that从句
如此……以至于……
条件状 if,unless
如果;除非
语从句 as/so long as
只要
让步状 语从句
though,although,while,as even if,even though no matter+what/who,whatever/whichever...
