1、從先行詞來看

同位語從句與名詞之間該名詞是需要做特殊說明的名詞如idea,fact,news,hope,belief,suggestion,word,thought,doubt,truth,possibility,promise,order等有一定內(nèi)涵的名詞

Theyweredelightedatthenewsthattheirteamhadwon.

當(dāng)聽到他們的球隊贏了的消息時，他們欣喜若狂。2、同位語從句的功能與性質(zhì)

同位語從句是名詞從句,其作用相當(dāng)于一個名詞,對前面抽象名詞的進(jìn)一步的說明和解釋。

Thenewsthatourteamhaswonthegamewastrue.我們隊贏了那場比賽的消息是真的。

(補充說明news到底是一個什么消息?)3、從引導(dǎo)詞that來看

引導(dǎo)詞that在同位語從句中是連詞,只起連接作用,無具體詞義,that不可省略

ThenewsthathewillleaveforShanghaiistrue.他將要去上海的消息是真的.

(that只起連接從句的作用,所以此句是同位語從句)4、引導(dǎo)詞擔(dān)當(dāng)成分時的省略

引導(dǎo)定語從句的關(guān)聯(lián)詞在從句中作賓語或狀語時,可以省略或被其他詞代替；介詞+which

同位語從句的引導(dǎo)詞一般不能省略,更不能被代替，試比較：

（1）Thenewsthatsheheardisfalse.她聽到的消息是假的.

（2）Thenewsthatshewillgoabroadisfalse.她將出國這消息是假的.

例（1）是定語從句,that可省略；例（2）是同位語從句，that不能省略。同位語從句與定語從句區(qū)別:1.從詞類上區(qū)別同位語從句前面的名詞只能是idea,fact,news,hope,belief,suggestion,proposal,word,thought,doubt,truth,possibility,promise,order等有一定內(nèi)涵的名詞，而定語從句的先行詞可以是名詞,代詞,主句的一部分或是整個主句。Hetoldmethenewsthathewouldcomehomefromaboardsoon.Wordcamethathehadbeenabroad.據(jù)說他已經(jīng)出國了。Ourteamhaswonthegame,whichmadeusveryhappy.我們的隊贏了,這讓我們很高興。(定語從句)2.從性質(zhì)上區(qū)別定語從句是從句對其先行詞的修飾或限制,屬于形容詞性從句的范疇;而同位語從句是從句對前面抽象名詞的進(jìn)一步的說明和解釋,屬于名詞性從句的范疇，如:Thenewsthatourteamhaswonthegamewastrue.我們隊贏了那場比賽的消息是真的。(同位語從句,補充說明news到底是一個什么消息)Thenewsthathetoldmeyesterdaywastrue.昨天他告訴我的那個消息是真的。(定語從句,news在從句中作told的賓語)3.從引導(dǎo)詞及其在句子中的成分上區(qū)別有些引導(dǎo)詞如how,whether,what可以引導(dǎo)同位語從句,但不能引導(dǎo)定語從句。如:Thatquestionwhetherweneedithasnotbeenconsidered.我們是否需要它這個問題還沒有考慮。(同位語從句)引導(dǎo)詞that引導(dǎo)定語從句時,在從句中一般作主語或賓語(指物時還可以用which代替),并且作賓語時常常省略，that在同位語從句中僅起連接作用,不充當(dāng)任何成分,并且不能省略,也不能用which來代替，如:Theorderthatweshouldsendafewpeopletohelptheothergroupswasreceivedyesterday.我們應(yīng)派幾個人去幫別的幾個小組的命令昨天收到了。(同位語從句,是對order的具體解釋,that雖不作成分,但不能省略)Theorderthatwereceivedyesterdaywasthatweshouldsendafewpeopletohelptheothergroups.我們昨天收到的命令是我們應(yīng)該派幾個人去幫助別的幾個小組。(定語從句,是名詞order的修飾語,that在從句中作received的賓語,可以省略)Practice判斷同位語從句與定語從句1.Thenewsthattherearenolivesonthemoonisknowntousall.()2.Thenewsthatyouheardisnottrue.()3.Haveyouanyideawhohewentwith?()4.Isthereanyhopethattheywillbehomeintime?()5.Theproblemthatyoureferredtodoesn’texistatall.()同位語從句的常見結(jié)構(gòu)（一）由that引導(dǎo)eg.Ihavenodoubtthathewillovercomeallthisdifficulties.

我毫不懷疑他能跨越所有的困難。

（二）由whether引導(dǎo)eg.Thequestionwhethertheywillhelpusisstillconfusedme.

我依然疑惑他們是否會幫我們。

（三）由其他詞引導(dǎo)的同位語從句eg.IhavenotmadeupmymindwhatelectivesubjectsIamtotakenextterm.

我還沒有決定好下學(xué)期上哪些選修課。

Whenyouareabouthalfwaythroughthestory,trytomakeaguesshowtheplotwilldevelop.

當(dāng)你把故事讀到一半時，猜測一下情節(jié)將如何發(fā)展。

（四）同位語從句與被修飾名詞的分割:有時，為了保持句式的平衡，將同謂語從句與被修飾的名詞分割，其間出現(xiàn)其他成分。eg.Concernswereraisedthatthelawmighthavenopowertopunishthesemudererswhohavemoneyorstatus.
