高中英语讲义名词性从句（主从、表从、宾从，同从）
1，陈述句做名从用连词thatSVthat表主句肯定从句完整，不做成分。主从可用it做形式主语，宾从第一个that可省略。Youstudyhard主从：Thatyoustudyhardisk
ow
tousItisk
ow
tousthatyoustudyhard表从：Myopi
io
isthatyoustudyhard宾从：Ithi
kthatyoustudyhard…a
dthat不能省略…同从：Myopi
io
thatyoustudyhardisk
ow
tous比较同从和主从！一般抽象名词后对其进行解释和说明的完整句子就是其同位语从句，不完整就是定语从句。Iappreciateyourideathatwehavea
exameveryweek（that后完整同从）Iappreciateyourideathatyoucameupwithlasttime（that后不完整定从）
2，一般问句做名从用连词whether是否SV，whether表主句不肯定从句完整，宾从中可用if（介词后或宾从后有or
ot时只用whether）。Doesyourfrie
dlikeE
glish主从：Whetheryourfrie
dlikesE
glishis
’tclearItis
’tclearwhetheryourfrie
dlikesE
glish表从：Myquestio
iswhetheryourfrie
dlikesE
glish宾从：Ido
’tk
owwhetherifyourfrie
dlikesE
glish同从：Myquestio
whetheryourfrie
dlikesE
glishis
’tclear
3特殊问句做名从用疑问词（连词）SV疑问词做主语时直接谓语。连接代词（whatwhichwhowhose…）表主句不肯定从句不完整，连接副词（whe
wherewhyhow）表主句不肯定从句完整。
Wheredidyougojust
ow主从：Whereyouwe
tjust
owis
’tclearItis
’tclearwhereyouwe
tjust
ow表从：Myquestio
iswhereyouwe
tjust
ow宾从：Iwo
derwhereyouwe
tjust
ow同从：Myquestio
whereyouwe
tjust
owis
’tclear
当主句为现在时态从句时态不受影响，当主句为过去时态从句就应该变成过去的某种时态，但客观真理总用一般现在时，有固定过去时间总用过去时。
高频考点1，当主从句都缺成分时指物用whatwhateverwhichever有范围指人用whoeverwhomever做宾语Thebuildi

又可引导名从（从句在主句中做成分）。_Nomatterwhowhoeverhasbroke
