(十一)定语从句一、关系代词引导的定语从句关系代词who,whom,whose,which,that引导定语从句时,可在从句中作主语、宾语、定语等句子成分
who代指人,作主语或宾语;whom代指人,作动词宾语或介词宾语;whose代指人(=ofwhom)或物(=ofwhich),作定语;which代指物,作主语或宾语;that代指人或物,作主语、宾语或表语
ThisisthedetectivewhocamefromLondon
Thebookwhich/thatIamreadingiswrittenbyThomasHardy
Thedeskwhoselegisbrokenisveryold
Heisnolongertheboythatheusedtobetwoyearsago
使用关系代词时应注意以下几点:(1)“介词+关系代词”可以引导定语从句,但关系代词只可用whom或which,不可用who或that
Theroominwhichthereisamachineisaworkshop
Inthedarkstreet,therewasn’tasinglepersonto_whomshecouldturnforhelp
(2)“whose+n
”引导定语从句时,可换成“the+n
+ofwhom/which”或“ofwhich+the+n
Helivesinabighousewhosewindowfacesthesea
Helivesinabighousethewindowofwhichfacesthesea
Helivesinabighouseofwhichthewindowfacesthesea
(3)which引导的定语从句还可修饰前面整个主句,此时which相当于andthis
Hesucceededinthecompetition,whichmadehisp
