wherewhy。that偶尔也作关系副词。5、确定关系词的步骤（1）先找关系词，看先行词指的是什么。（2）看关系词在从句中所充当的成分。二、语法解析语法解析（一）That与which区别1、在限制性定语从句中，当先行词指物时，下列情况的关系词宜用that（1）先行词被①形容词最高级②序数词③o
ly、a
y、few、little、
o、all、o
eof等修饰时。（2）先行词为all、much、little、
o
e、few、o
e、somethi
g、a
ythi
g、everythi
g等不定代词时。▲当somethi
g表示具体的事物，重要的东西，重要的人物等确定意义时，它是名词，关系代词用that或which均可。Therewasthemysterioussomethi
gwhichthattheyhadworkedsohardtofi
dradium（3）先行词中既有人又有物时。Hetalkedaboutsomewritersa
dbooksthatwereu
k
ow
tousall（4）先行词在主句中作表语关系词在从句中作表语时。Thevillageis
olo
gertheo
ethatwas5yearsago（5）当主句中含有疑问词which时。2、宜用which的情况（1）在非限制性定语从句中（2）在关系词前有介词时（3）当先行词本身是that时MaryhasabookwhichisverypreciousThisisahousei

（4）当关系词后面有插入语时用which引导定语从句。HereistheE

which”或省去。Ido

f（二）as与which1、关系代词as在从句中作主语、宾语和表语。（1）先行词被such和thesame修饰，或句型asma
y（much）中，从句都用as引导。SuchbooksasyouboughtareusefulTheschoolisjustthesameasitwas10yearsage
▲①such…that…引导的结果状语从句，that在从句中不充当句子成分Theyaresuchlovelychildre
thatwelovethemmuch②thesame…that…引导定语从句。Iwa

ow
（2）无先行词的非限制性定语从句用as和which引导。区别：①意义上：as含有“这点正如这点正如……一样。一样”。这点正如一样②位置上：as从句可置句首，也可在另处。Thereislotsofairi
