1、定语从句1、功能:=形容,修名或代,在句中作定一:先行:被定从句所修的二:关系:用来接定从句,并在从句中代表先行。在从句中充当的成分:主、学会找关系,看先行指的是什么-----先行,看关系在从句中所充当的成分。2、一般用法先行是物:whichthat先行是人:whowhomthat关系代在从句中作可以省略。e.g.Theyoungman(whom)yousawwasourmanager.Thereissomething(that)wemustkeepinmind.限制性定从句与非限制性定从句(逗号隔开非限制)1)限制性定从句:从句与主句关系密切,去掉从
2、句,主句意不完整,甚至不合。e.g.Iwastheonlypersoninourofficewhowasinvited.(去掉定从句,意思就不完整)2)非限制性定从句:从句先行关系不密切,去掉定从句,意思仍然完整。形式上用逗号隔开,不能that用引。e.g.Tom’sfather,whoisoversixty,stillworksharddayandnight.that与which的区1)用that而不用which的情况①先行不定代all,anything,nothing,;②先⋯行有最高修,有序数修;③先行有only,very,any等修;④先
