学习定语从句的几个问题
1、掌握以上关系代词、关系副词的含义及使用时,要特别注意以下几点:
1)指物时宜用that的情况:
a.当先行词为all,much,little,few,none,something,anything,everything,nothing等不定代词时。
allthatcanbedonehasbeendone.
b.当先行词既指人又指物时。
hespokeofthemenandthething(that)hehadseenabroad.
c.当先行词被序数词或形容词的最高级修饰时。
thisisoneofthebestfilmsthatihaveeverseen.
d.当先行词被thevery,theonly,thelast,any,every等修饰时。
thisisoneoftheverybookthatiamlookingfor.
e.当先行词是疑问词who,what,which时。
whothathassuchahomedoesn’tloveit?
f.关系代词在从句中作表语。
maryisnolongerthegirlthatsheusedtobe.
2)关系代词as和which都能引导非限定性定语从句代表整个句子的内容,as
引导的从句可位于句首或句末,which引导的定语从句则不能位于句首。
whichyouknow,heisagoodman.(×
)
asyouknow,heisagoodman.(√)
3)关系副词when,where,why其含义相当于onwhich,inwhichforwhich等,可以互换:
thedaywhen/onwhichimethimfirstwasmay1st.共5页,当前第3页12345
idon’tknowthereasonwhy/forwhichhedidn’tcome.
47)whose指物时,可以与ofwhich等结构互换,但应注意与冠词的位置关系:
thisisthebookthecoverofwhich/ofwhichthecover/whosecoverisblue.
5)有时可用代替关系副词。
在口语中常省略。
thisisthereason(why/forwhich/that)hecamelate.
6)先行词是专有名词、整个句子或世界上独一无二的物质名词时,一般用非限定性定语从句修饰。
thesun,whichgivesuslightandheat,isverybig.
7)在先行词和定语从句之间有无逗号有时会引起名义的变化:
hesaidnothingthatmadeherangry.他没说使她生气的话。
hesaidnothing,whichmadeherangry.他一言不发,这使她很生气。
2、定语从句与强调结构
itistheplacewheretheylivedbefore.
itisintheplacethattheylivedbefore.
第一个句子为定语从句,where指代theplace,在定语从句中作状语,第二个句子为强调结构,强调intheplace,that没有意义,把放回后面句子,句子意思完整。
whereisitthathefoundthelostwatch?
(强调句型,强调疑问副词where.)
whereisthewatchhefoundyesterday?
(定语从句,that指代thewatch.)
3、定语从句中的先行词
isthisbooktheonethatyouboughtyesterday?
isthisthebookthatyouboughtyesterday?
第一个句子中,thisbook是主句的主语,theone是先行词。
在第二个句子中this是主句的主语,thebook是先行词。
一定要避免出现:
isthisbookthatyouboughtyesterday?
4、定语从句与同位语从句
定语从句相当于形容词,它对先行词起修饰、描述或限制作用,而同位语从句则相当于名词,对其前面的词给予说明或作进一步解释,即说明该词所表示的具体内容。
例如:
thenewsthatweheardisnottrue.(定语从句)
thenewsthathewontheprizeisnottrue.(同位语从句)
另:
在“havenoidea+从句”结构中,其从句都作idea的同位语。
ihavenoideawhenshewillbeback.
