【要點總結(jié)】

名詞性從句由不同的引導詞引導，從句一般保持陳述語序。

引導名詞性從句的連接詞可分為3類：

Lthat引導的名詞性從句

that只起連接主句和從句的作用，在從句中不擔任任何成分，本身也沒有任何意義。該從句作主語通常用it

作形式主語,而將從句置于句末。

Scientistshaveobtainedmoreevidencethatplasticisfindingitswayintothehumanbody.（同位語從句）

Itissuggestedthatweshouldlimittheamountofcarstoimproveourenvironment.（主語從句）

2.wh?詞引導的名詞性從句

wh-詞包括who、whom>whose>whoever>what、whatever>which>whichever等連接代詞和where>when>

why等連接副詞。wh-詞既起連接作用，還可充當主語、賓語和表語等。從句作主語也常用it作形式主語,

而將wh-從句置于句末。

Itremainstobeseenhowtheseobstacleswillhelporhurtitseconomy.

【重點提示】

（l）what引導的名詞性從句

what作連接代詞引導的名詞性從句既可以表示一個問“什么……?”的問題，也可以表示相當于“名詞/代詞+

關(guān)系代詞引導的定語從句”的結(jié)構(gòu),意思是“所...的事/物“，相當于thething(s)that/which...o

Thisiswhat(=thethingthat)wehavebeenlookingforwardtoforyears.

(2)wh-ever既可引導名詞性從句，又可引導讓步狀語從句;而nomatterwh-只能引導讓步狀語從句。

Thegoldmedalwillbeawardedtowhoeverwinsthefirstplaceinthebicyclerace.

Nooneisallowedtobreaktheregulations,whoeverheis.

3.if、whether引導的名詞性從句

(1)引導主語從句、表語從句、同位語從句時一般用whether,不用if。

Thequestioniswhethertechnologyisgoingtobeourservantorourmaster.

(2)whether與if引導賓語從句時大多數(shù)情況下可以互換，但下列情況只能用whether:

①后面直接跟ornot時

Theynowhavetwoweekstodecidewhetherornottobuyit.

②用于介詞后引導賓語從句時

Butifhe'soutthereeverydayandplayinghard,youshouldpraisehiseffortregardlessofwhetherhisteamwins

orloses.

考點2主語從句

【要點總結(jié)】主語從句是在復(fù)合句中充當主語的從句,通常放在主句謂語動詞之前或由形式主語it代替,

而本身放在句子末尾。

【重點提示】it作形式主語的句型有：

(l)It+be+名詞+從句

Itisafactthat...事實是...

Itisgoodnewsthat...........是好消息

Itisaquestionthat...........是個問題

Itiscommonknowledgethat...........是常識

類似的可用于該結(jié)構(gòu)的詞還有:apity、awonder>agoodthing、nowonder>asurprise等。

Itisgoodnewsthatourteamhaswonthechampionship.

ItisapitythatIhavemissedawonderfulboxingmatch.

(2)It+be+形容詞+從句

Itisnecessarythat…有必要...

Itisclearthat...很清楚...

Itislikelythat…很可能...

Itisimportantthat...重要的是...

類似的可用于該結(jié)構(gòu)的形容詞還有:strange、naturaRobvious>true、good>wonderful>possible>unlikely>

unusuaRcertain>evident>worthwhile>surprising>interesting>astonishing等。

Itislikelythatthegoodshavemetwithsomeaccidentontheway.

Itisstrangethatheshouldhavegoneawaywithouttellingus.

(3)It+be+過去分詞+從句

Itissaidthat…據(jù)說...

Itisreportedthat...據(jù)報道...

Ithasbeenprovedthat...已證明...

Itmustbepointedoutthat...必須指出...

類似的可用于該結(jié)構(gòu)的過去分詞(詞組)還有:known、estimated>expected>believed、thought、hoped>noted>

discussed>required>decided>suggested>demanded>madeclear>foundout等。

Itisreportedthattheaffectedareaisunderfurtherdetailedinvestigation.

Ithasbeenprovedthateverysubstance,nomatterwhatitis,ismadeupofatoms.

考點3賓語從句

【要點總結(jié)】賓語從句在復(fù)合句中起賓語的作用，既可作動詞的賓語，也可作介詞的賓語(作介詞的賓語

時必須由wh-疑問詞引導)。

l.that的省略與否

that引導賓語從句時，在句中不充當任何成分，在口語或非正式的文體中常被省去。但如果是由and連

接兩個并列的賓語從句時,第二個賓語從句前的that不可省略。

Hesaid(that)youweretooyoungtounderstandthematterandthathewasaskednottotellyou.

2.句子的語序

由who、whom、which、whose>what、when、where>why>how、whoever>whichever等弓I導的賓語從句,

應(yīng)注意從句的語序要用陳述語序。

Canyouexplainwhyhedidn'tcometothepartylastSunday?

【重點提示】

(l)think>believe>imagine>suppose等動詞引導的否定性賓語從句中，要把上述主句中的動詞變?yōu)榉穸ㄊ?

即將從句中的否定形式轉(zhuǎn)移到主句中。

Idon'tthinkthefoodhereagreeswithme.

Wedon'tbelievehestolemoneyfromtheshop.

⑵動詞doubt用在疑問句或否定句中時，其后賓語從句常用that作連接詞;用在肯定句中時，連接詞用

whether或if皆可,而不用thato

Doyoudoubtthathewillwinthematch?

Idon'tdoubtthathecandoagoodjobofit.

Heoftendoubtswhether/ifheisadequateasafather.

考點4表語從句

【要點總結(jié)】表語從句除了用that、what、when、why、whether、how等引導外，還可由because>asif(though)

等引導。that引導表語從句，無任何意義，只起連接作用，不可省略。

Withouthissupport,wewouldn'tbewherewearenow.

Byboatistheonlywaytogethere,whichishowwearrived.

Itlooksasifasandstormiscomingup.

Thefactofthematteristhatmostpeopleconsumefarmoreproteinthantheyactuallyneed.

【重點提示】

(l)whether可引導表語從句,但與之同義的if不用于引導表語從句。

Thequestioniswhetherhewilljoinusnexttime.

(2)Thatisbecause…指原因或理由。Thatiswhy…指由于各種原因所造成的后果。

Hedidnotseethefilmlastnight.Thatisbecausehehadtohelphislittlesisterwithherhomework.

Hehadseenthefilmbefore.Thatiswhyhedidnotseeitlastnight.

(3)當主語是reason時,表語從句要用that引導而不用becauseo

ThereasonwhyIwaslatewasthatmycarbrokedownontheway.

考點5同位語從句

【要點總結(jié)】同位語從句用于對前面出現(xiàn)的名詞作進一步說明，一般用連詞that引導。由于名詞的意義

不同,也可用whether、who、when、where>what>why、how等引導。常見的后跟同位語從句的名詞有fact>

idea、belief、news、hope>conclusion>evidence>suggestion>order>problem>report、decision>word(消

息)等。

Wecametothedecisionthatwemustactatonce.

Ihavenoideawhenhewillcomeback.

Wedon'tunderstandtheproblemwhythisisthebestchoice.

【重點提示】that引導同位語從句和定語從句的區(qū)別：

引導同位語從句的that不充當句子成分,且不可省略;that引導的定語從句成分是殘缺的,that代替先行詞在從

句中充當主語、賓語或表語,充當賓語時可省略。

Wearegladatthenewsthathewillcome.

聽到他要來這個消息我們很高興。（news的內(nèi)容就是thathewillcome,故此處that引導的是同位語從句）

Wearegladatthenewsthathetoldus.

聽到他告訴我們的這個消息我們很高興。（that從句是限制thenews的內(nèi)容的，即我們高興只是因為他告訴的

這個news而不是其他的news,故此處that引導的是定語從句）

【重點提示】語法填空題名詞性從句考法

第一步判斷是否屬于名詞性從句。第二步判斷名詞性從句中的連接詞；若從句中缺少主語、賓語或表

語，用連接代詞;若缺少狀語就用連接副詞;如果不缺少成分則要考慮意思是否完整，是否需要用whethcr/if;

如果不缺少成分且意思完整則用thato

【鏈接寫作】

名詞性從句包括主語從句、賓語從句、表語從句和同位語從句。名詞性從句在寫作中應(yīng)用廣泛,可以使

文章更加精練、簡潔、準確,可以讓文章更加出彩，所以我們建議考生在一篇寫作中盡量要加上1?2個名詞

性從句。如2023年新高考I卷書面表達：

IpromisedthatIwouldliveuptohisexpectationandneverstopwritinginEnglishthoughitwasmysecond

language.

我保證我不會辜負他的期望，盡管英語是我的第二語言，但我永遠不會停止用英語寫作。

該句中包含了that引導的賓語從句和though引導的讓步狀語從句。

再如2023年全國甲卷書面表達：

OneofhisachievementswasthathediscoveredthesourceoftheJinshaRiver,whichheprovedwasthesourceof

theYangtzeRiver.

他的成就之一是他發(fā)現(xiàn)了金沙江的源頭,他證明了金沙江就是長江的源頭。

該句中包含了that引導的表語從句和which引導的定語從句。

參考答案

l.B

【解析】考查賓語從句。句意：這取決于是否對于做這項工作感興趣。本句中的賓語從句是由whether引

導，whether在句中不充當任何成分，只起引導和連接作用，表示“是否“。AC兩項不能用于介詞unop的

后面；what要在句中充當成分。故選B。

2.D

【解析】試題分析：考查連詞。whoever(hebelieved)hadastrongsenseofresponsibility.hebelieved是插入語,

去掉看就比較明顯了，要用主格.to后面的是一個賓語從句,whoever是這個從句的主語.

考點：考查連詞

3.A

【解析】考查賓語從句。句意：Aron完成這個實驗是為了做他喜歡做的事情。inordertodosth.是固定短

語，譯為“為了做某事”，本處"helovestodo”相當于do后面的sth.,作do的賓語，是一個賓語從句，

空處是引導詞，在從句中作賓語，表示“什么……的事情"，用what；故選A項。

4.B

【解析】考查賓語從句。句意：——我想知道為什么珠穆朗瑪峰國家自然保護區(qū)提供公共汽車服務(wù)。-

為了更好地平衡旅游發(fā)展與環(huán)境保護。此處是賓語從句，用陳述句語序，根據(jù)回答應(yīng)該是why引導賓語從

句。故選B。

5.B

【解析】考查表語從句。本句是一個一般疑問句，陳述語序是Thisresearchcenteriswhereyoumetsome

foreignguestslastweek.?where引導的是一個表語從句，where在句中做狀語。特別注意D選項，因為缺

少先行詞所以D錯誤。結(jié)合句意可知B正確。句意：這家研究中心是不是上星期你遇見一些外國客人的地

方？

6.B

【解析】考查賓語從句的連接詞。句意：老師們應(yīng)該意識到，學生也許會忘記你教過的知識或做過的事情，

但是他們永遠不會忘記你帶給他們的感受?？崭裉幦鄙贍钫Z，即“你帶給了他們怎樣的感受”，所以要用連

詞howo故選Bo

7.C

【解析】考查定語從句和賓語從句。句意：警察分析了騎自行車和步行的人陷入交通事故的主要原因以及

他們應(yīng)該做什么來預(yù)防。分析句子結(jié)構(gòu)并結(jié)合句意可知，第一空為定語從句，先行詞為reasons,從句中缺

少原因狀語，用why；第二空為賓語從句，連接詞在從句中作do的賓語，表達“做什么”，用what。故C

項正確。

8.B

【解析】考查讓步狀語從句和主語從句。句意：一無論我什么時間看電視，我都會把聲音調(diào)低一點，從不

發(fā)出任何噪音。一很好，無論你做什么，都不要打擾別人。不管你有多重要，永遠不要忘記別人的感受。

首先看第一個空，根據(jù)句意和句子結(jié)構(gòu)可知，本句為讓步狀語從句，表示“無論何時”我看電視，都會調(diào)低

聲音，故應(yīng)用Whenever引導讓步狀語從句，意為“無論何時”，相當于Nomatterwhen。再看第二空，根據(jù)

句意和句子結(jié)構(gòu)可知，句子為主語從句，“youaredoing”在句中作主語，從句中缺少aredoing的賓語，

表示無論做什么事，故用Whatever來引導主語從句，意為“任何事情"，相當于anythingwhat。再看第三個

空，根據(jù)句意和句子結(jié)構(gòu)可知，本句為讓步狀語從句，表示“不管多么重要”，故應(yīng)用Nomatterhow引導讓

步狀語從句，意為“不管多么"，相當于however。故選B項。

9.B

【解析】考查固定句型。句意：我既沒有雨衣也沒有雨傘。這就是我渾身濕透的原因。根據(jù)"
