一、定義定語(yǔ)從句可以分為限制性定語(yǔ)從句和非限制性定語(yǔ)從句。結(jié)構(gòu)限從：先行詞+引導(dǎo)詞（關(guān)系代詞、關(guān)系副詞）…非限：先行詞，引導(dǎo)詞（不用that和why）…意義限從：對(duì)先行詞起限定作用，從句與先行詞關(guān)系密切（不可省略）非限：對(duì)先行詞起拓展資料說(shuō)明作用，從句與先行詞關(guān)系不密切（可省略）修飾先行詞或整個(gè)句子。定語(yǔ)從句就其與先行詞的關(guān)系可分為限制性定語(yǔ)從句和非限制性定語(yǔ)從句。non-restrictiverelativeclauses一、形式不同限制性定語(yǔ)從句與其先行詞關(guān)系密切，其間通常不用逗號(hào)隔開(kāi)，非限制性定語(yǔ)從句與其先行詞關(guān)系不密切，常用逗號(hào)隔開(kāi)。如：Thenumberofpeoplewho/thatowncarsisincreasing.IspoketoDr.Smithjustnow,whoisalwaysreadytohelpothers.二、作用不同限制性定語(yǔ)從句對(duì)先行詞進(jìn)行修飾和限制，如果去掉會(huì)造成句意的不完整；非限制性定語(yǔ)從句對(duì)先行詞是修飾，拓展資料解釋說(shuō)明或?qū)χ骶溥M(jìn)行評(píng)述，去掉不影響。如：Franklinwasthefirstmanwhodiscoveredthenatureofelectricity.Franklin,whowasveryyoung,discoveredthenatureofelectricity.先行詞往往是抽象，不夠具體的先行詞：具體，從句旨在拓展資料說(shuō)明評(píng)述先行詞或主句三、先行詞不同限制性定語(yǔ)從句的先行詞一般是名詞或代詞，非限制性定語(yǔ)從句的先行詞既可以是名詞或代詞,也可以是主句的一部分或整個(gè)主句。如：Thingsthenimproved,whichsurprisedme.（先行詞為整個(gè)主句）
