ThisisthehighestscorethatIcanget.2.当先行词是something、anything、nothing、everything、all、any等指物的不定代词（指人时必须用who）的时候。

Doyouhaveanythingthatmustbedone.3.当先行词被theonly、thevery（正是）修饰时。

That’stheonlythingthathurtsme.4.当先行词不止一个，也就是先行词既有人又有物的时候。Theoldmanandhisdogthatwesawyesterdaydidnotappearagain.注意：that、which、whom、who在从句中充当宾语时可以省略1.Whoistheman(whom/that)youtalkedwithjustnow?2.Thisisthebook(which/that)Ireadyesterday.3.I’llneverforgettheday(which/that)Ispentinthefarm.分类：限制性定语从句：删掉后整句话的句意不明确Doyouknowthegirlwhojustcamein?非限制性定语从句：前有逗号，删掉后对整句话的句意影响不大Hismother,whoisinShanghainow,iscominghomenextweek.非限制性定语从句不用that,其他规则和限制性定语从句的规则一致。which与as引导非限的区别1.as引导的非限制性定语从句可置于句首，而which则不能。2.as引导非限制性定语从句时有“正如”之意，而which没有。3.as常做实义动词（如expect,guess,hear,know,remember,see,say,show,tell,watch等）

的宾语，这类动词与as几乎成了一种固定搭配，而which则没有这种固定搭配。4.as表明从句和主句是同一件事，Which不是。as常用的固定表达：asweallknow=asiswellknownasoftenhappensasyouseeascanbeseenasmaybeimaginedasIcanrememberasweexpectashasbeensaidbefore限制性定语从句和非限制性定语从句Heistheteacher()everybodylikes.Mr.Zhang,()everybodylikes,iscomingtomorrow.Ilikethebook()yougavemeyesterday.Heleftmeabook,()isveryusefulforme.Hewasoftenlate,(
