Non-RestrictiveAttributiveClause限制性限制性定从和非限制性定从的区分1（1）限制性定语从句：限制性定语从句是先行词不可缺少的部分，去掉之后，主句意思不明确。（2）非限制性定语从句：非限制性定语从句是对先行词的附加说明，去掉之后，意思明确，与主句通常用“，”隔开，把非限制性定语从句放在句子中，其前后都需要用逗号隔开。eg.Pleasepassmethebookwhich/thatisonmydesk.

PleasepassmemyChinesebook,whichisonmydesk.例句分析eg.Iwastheonlypersonwhowasinvited.例句分析我是我们办公室唯一被邀请的人。(如果把从句部分去掉,整个句子的含义就变了)Iwastheonlyperson.eg.Hisdog,whichwasnowveryold,becameillanddied.

他的狗当时很老了,生病后就死了。(去掉从句,主句的意义仍然完整:他的狗生病死了。)

先行词被no等词修饰或先行词为nothing，little,few等否定意义的词修饰时。“代”：【指代事物时】，先行词为不定代词，或者被不定代词修饰。常用的不定代

词有some,all,any,much,many,something...

【指代人时】则不受此规则限制。“唯一”：先行词被theonly

修饰时，指物表唯一。“问题”：句中已有who

或者which,为了避免重复。“序数”：先行词中有序数词修饰时。“最”：先行词中有形容词最高级修饰时;先行词被thevery修饰，表示“恰恰是”。“多”：先行词既指人又指物。只用which,who,whom的情况①在非限制性定语从句中，只能用which指代物，用who/whom指人。

[例]Hehasason,whohasgoneabroadforfurtherstudy.②在由“介词+关系代词”引导的定语从句中，只能用which指物，

whom指人

Ididn'tliketheway(that/inwhich)shetalkedtome.她对我说话的方式，定语从句,不缺少成分，作状语，可以理解为方式状语。Testhowwellyoumasterit?PracticeYesterdayMr.Lifinallyboughthisownhouse,_______isahospital.
