高考英語語法專項講義：定語從句難點精講簡明概述：定語從句在句中充當定語的角色，修飾句中前面所提到的名/代詞。被修飾的名/代詞稱為先行詞。關系代詞（who,whom,whose,which,that）：注：沒有what關系代詞所代替的主要是人或物的名/代詞，在句中充當主語、賓語、定語等成分。who,whom,that

都可代替人例句：Is

theboy

who/that

cheatedintheexamination?(who/that作為從句主語，代替theboy)Heis

theman

whom/that

wewon’trecruitduetohiscriminalrecords.(who/that作為從句賓語，代替theman)whose可指代人或物注：如果whose指物的話，也可以用ofwhich來代替。例句：Ourconversationwasstoppedby

thatfashionshow

(which/that)youweretalkingaboutjustnow?（作賓語時可省）關系副詞（when,where,why）：關系副詞分別代替的先行詞為時間、地點和原因，在從句中充當狀語的角色。注：when,where,why也可用“介詞+which”來代替。例句：Thiswas

themoment

when/atwhich

where/inwhich

why/forwhich

thereisasevereshortageoffundsforour

research?注：that

是可以代替關系副詞的，即that可取代“when,where,why”和“介詞+which”的形式。（在口語中that可省略）注：介詞后面的關系詞不能省略，而且that前不能有介詞例句轉換：Thiswas

themoment

research?限制性/非限制性定語從句重點概括整理：限制性定語從句先行詞是不能省略的，因為省了先行詞的話，句子的意思就會變得不完整和不明確，缺少必要的說明解釋。而非限制性定語從句是先行詞的額外說明，是可以省略的，省了也不會影響句子的意思和整體性，并且與主句之間常用“，”隔開。比較例句：Thisis

thebook

(which/that)

I

boughtyesterday.（限制性）Thisbook,

I

boughtyesterday,isveryinspiring.（非限制性）通常是非限制性定語從句的情況分析：StevenSpielberg,(whom)

I

admireverymuchinHollywoodmovie-makingfield,won

another

OscarAwardthisyear.（專有名詞/人名）My

beloveddog,(which)

I

bought5yearsago,hascaughtabadcoldrecently.（有物主代詞的時候）This

experiment,whichwasconductedlastweekends,provestobeabigsuccess.（有指示代詞的時候）Herchildwasalwaysabsent-mindedinlearning

and

failedinexams,

which

madeher

disappointed

onceagain.（由which代替整句主句）關系代詞that的特殊用法總結（只能用that的情況）：先行詞既包含人又包含物，只用that，不用which例句：Thevolunteersweretalkingabout

thenonprofitorganizationanditsstaff

that

made

anindelibleimpression

onthem.當不定代詞作為先行詞（如anyone，anything，nothing，any，everything，something，little，few，much，all等），只用that，不用which例句：Heshared

everything

withus

that

arousedhisinterestinchemistryatschool.先行詞用theonly/very修飾時，只用that，不用which例句：Thegirlis

theonly

student

that

willblushwithshynesswhentalkingwithboys.先行詞是序數詞、數詞、形容詞最高級時，只用that，不用which例句：The
