（若把從句去掉，則不明白是哪位科學(xué)家。）定語從句限制性e.g.WeknewthephysicalscientistHawkins,whohadstudiedtheproblem.

（若把從句去掉，仍然知道是哪位科學(xué)家。）在意義上是先行詞不可缺少的定語，如果省略，所修飾的先行詞往往不明確，前面一般沒有逗號隔開。往往是對先行詞的附加說明，為先行詞提供補充信息，即使去掉，也不會影響先行詞的明確性，與主句之間常用逗號隔開。非限制性

在much或all后用that，不用which，作定語從句的賓語時可以省略。例如：

Therewasnotmuch(that)wecoulddowhenitwasraining.

Thatisallthatworks.

關(guān)系代詞作動詞的間接賓語時，用to或for。例如：

Whoisthegirlthathegavetheflowerto?

Whoisthegirlthathegavetheflower?

無關(guān)系代詞時，也要用to或for。例如：

TheladyIwrotethepoemforwasmysister.限制性定語從句補充知識

正式英語中，介詞可置于從句之首，whom或which之前。例如：

Thisisthegreatwritertowhomourteacherwasreferring.

Heaskedaquestiontowhichtherewasnoanswer.

注意，介詞不可置于who或that之前。

定語從句的謂語如果是以介詞結(jié)尾的短語動詞，則不可把介詞移至從

句之首。例如：

Hereceivedtheemailhewaslookingforwardto.限制性定語從句補充知識1.Where引導(dǎo)定語從句時，先行詞為表示地點的名詞，關(guān)系詞在從句中作地點狀語，可用“in,at等介詞+which”來替換。Theschoolwheremystudiesisnearapark.=Theschoolinwhichmystudiesisnearapark.關(guān)系副詞when,where,why的用法Thisistheplace_____(which/where)Ispendmychildhood.Thisistheplace_____(which/where)Ivisitedlastsummer.第一空填where(從句中spend是謂語，mychildhood是賓語where代指theplace在從句中充當(dāng)?shù)攸c狀語)第二空填which(which指代前面的theplace在從句中充當(dāng)visit的賓語)2.When引導(dǎo)定語從句時，先行詞為表示時間的名詞，關(guān)系詞在從句中作時間狀語，可用“at,in,on,during等介詞+which”來替換。I’llneverforgetthedaywhenIjoinedtheteam.=I’llneverforgettheday

onwhich

Ijoinedtheteam.I'llwillneverforeverthedays______(which/when)wespendtogether.I'llwillneverforeverthedays______(which/when)welivetogetherinthecountry.第一空填which(which指代前面的thedays在從句中充當(dāng)spend的賓語)第二空填when(從句中we是主語，live是謂語，inthecountry是賓語，when指代thedays在從句中充當(dāng)時間狀語)
