1、主从复合句要点精编（总复习）三类从句：名词性从句、定语从句、状语从句从句考两点：连词(是否有意思，在句中充当什么成分，是否可省)、语序（陈述语序）。陈述语序：Thephotographswillshowyouwhatourvillagelookslike.（除了what’sthematter不变）名词性从句1.“主语”的位置是句子，那个从句就是“主语”从句。（宾语、表语、同位语）2.名词性从句连词有：(下划线的连词定语从句中不可用)（1）that;（通常不可省，只有在宾语从句中可省。）（2）wh-(what,who,who

3、f区别主语从句、表语从句、同位语从句、介词后的宾语从句、直接加动词不定式whether（todo）、whetherornot连用时都不能使用用if。If只在动词后的宾语从句中可以与whether互换。Eg.Idon’tknowif/whetherI’llbefreetomorrow.6.whatever和nomatterwhat区别这两者在让步状语从句中可互换，名词性从句中只能用whateverNomatterwhodestroystheforestwillbepunished.×Whoeverdestroysthefor
