（若把从句去掉，则不明白是哪位科学家。）定语从句限制性e.g.WeknewthephysicalscientistHawkins,whohadstudiedtheproblem.

（若把从句去掉，仍然知道是哪位科学家。）在意义上是先行词不可缺少的定语，如果省略，所修饰的先行词往往不明确，前面一般没有逗号隔开。往往是对先行词的附加说明，为先行词提供补充信息，即使去掉，也不会影响先行词的明确性，与主句之间常用逗号隔开。非限制性

在much或all后用that，不用which，作定语从句的宾语时可以省略。例如：

Therewasnotmuch(that)wecoulddowhenitwasraining.

Thatisallthatworks.

关系代词作动词的间接宾语时，用to或for。例如：

Whoisthegirlthathegavetheflowerto?

Whoisthegirlthathegavetheflower?

无关系代词时，也要用to或for。例如：

TheladyIwrotethepoemforwasmysister.限制性定语从句补充知识

正式英语中，介词可置于从句之首，whom或which之前。例如：

Thisisthegreatwritertowhomourteacherwasreferring.

Heaskedaquestiontowhichtherewasnoanswer.

注意，介词不可置于who或that之前。

定语从句的谓语如果是以介词结尾的短语动词，则不可把介词移至从

句之首。例如：

Hereceivedtheemailhewaslookingforwardto.限制性定语从句补充知识1.Where引导定语从句时，先行词为表示地点的名词，关系词在从句中作地点状语，可用“in,at等介词+which”来替换。Theschoolwheremystudiesisnearapark.=Theschoolinwhichmystudiesisnearapark.关系副词when,where,why的用法Thisistheplace_____(which/where)Ispendmychildhood.Thisistheplace_____(which/where)Ivisitedlastsummer.第一空填where(从句中spend是谓语，mychildhood是宾语where代指theplace在从句中充当地点状语)第二空填which(which指代前面的theplace在从句中充当visit的宾语)2.When引导定语从句时，先行词为表示时间的名词，关系词在从句中作时间状语，可用“at,in,on,during等介词+which”来替换。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在从句中充当spend的宾语)第二空填when(从句中we是主语，live是谓语，inthecountry是宾语，when指代thedays在从句中充当时间状语)
