高一英语名词性从句专项练习
名词性从句
一.概念
名词性从句共有四种:
1.主语从句2.表语从句3.宾语从句4.同位语从句
二.知识点
1.主语从句:
主语从句在整个句子中作主语。
(1)主语从句中的that不充当句子的成分,只是单纯的连接词,通常不省略。
分句置于句首时,that绝对不可以省略。
Thatthedrivercouldnotcontrolhiswarwasobvious.
Itwasobviousthatthedrivercouldnotcontrolhiscar.
2.表语从句:
表语从句出现在系动词后,充当表语。
Thetroubleisthatweareshortofmoney.
Goandgetyourcoat.It’swhereyouleftit.
引导表语从句除了上述三类词外还有because,asif/asthough等等
Thereason(why/forwhich…..)isthat……
It/This/Thatisbecause……
连系动词“appear,look,seem”的两个常用句型
Itseems/appearsthat….
Itlooks/seemsasif/asthough……(与事实相符用陈述语气,与事实相反用虚拟语气)
3.宾语从句:
(that可以省略)及物动词,形容词和介词后加宾语从句作其宾语。
宾语从句时态与主句相呼应,但宾语从句表示的是客观真理或普遍现象除外
Theteachertoldus(that)theearthmovesaroundthesun
Iamafraid(that)Ihavemadeamistake.
Hewillhavetopayforwhathehasdone.
当宾语从句后带宾补时,要用“主语+谓语+it+宾补+that+从句,that不可省略
Ithinkitcertainthatshewilldowellinherexam.
that在宾语从句常可以省略,但由and或but连接两个或多个宾语从句时,仅可以省略第一个连词that
Hesaid(that)hehadeatennothingandthathewasn’thungry.
注意区别if引导的宾语从句和条件状语从句
Idon’tknowifhewillcome.(if是否)
Ifhecomes,I’llletyouknow.(if如果)
4.同位语从句:
(that不可省略)对前面的名词进一步说明。
用在下列名词fact,truth,news,idea,hope,belief,thought,doubt,order,suggestion,wordetc.
Theteachertoldusthefactthattheearthmovesaroundthesun
Thereisnodoubtthathewillcome.
Thereisdoubtwhetherhewillcome.
Hissuggestionthatwe(should)goforanoutingcheeredusup.
WordcamethatNapoleonwouldcometoinspectthem.
that引导的同位语从句与定语从句的区别:
在同位语从句中:
that不作成分,不可以省略;
在定语从句中:
that作成分,且作宾语时可以省略
Weareinterestedinthenewsthatsomeforeignerswouldvisitourschool.同位语
Weareinterestedinthenews(that/which)hetoldus.定语从句
when,where引导的同位语从句与定语从句的区别:
在定语从句中,when,where前有分别表示时间、地点的先行词;而在同位语从句中无此对应关系
Theyhavenoideaatallwherehehasgone.(同位语从句)
Goandgetyourcoat.It’sintheplacewhereyouleftit.(定语从句)
三.注意点:
1.疑问词whatever/whoever/however/whenever等既可以引导名词性从句,也可以引导让步状语从句,而nomatter+疑问词只能引导让步状语从句
总体规律:
whatever/whoever等词的使用范围比nomatterwhat/who等要广
Nomatterwhathappens,hewillnotmind.(√)让步状语从句(用逗号隔开)
=Whateverhappens,hewillnotmind.(√)让步状语从句
Nomatterwhatyousayisveryimportant.(×)
Whateveryousayisveryimportant.(√)主语从句(名词性从句)
Ibelievewhateverhesays.Whateverhesays,Iwillneverbelievehim.
2.who与whoever的区别
who是“谁”的意思,表示具有疑问,whoever相当于anyonewho“无论谁”
Whoeverleavestheroomlastoughttoturnoffthelights.
Canyoutellmewhothatgentlemanis?
6.当从句缺少主语、宾语或表语时,引导词通常用what。
Whatimpressedmemostwasherexcellentperformance.
Whatwecan’tgetseemsbetterthanwhatwehave.
Whatseemsbeneficialtousmaybeunfavorableforothers.
7.注意区分it…that…结构引导主语从句还是强调句
主语从句it指代句中that引导的内容(通常较长),去掉Itis/was,that,句子不成立
强调句句型:
Itis/was+被强调部分+that,去掉Itis/was,that,句子仍然成立。
Itisnaturalthattheyshouldhavedifferentviews.主语从句
Itisknowntoallthattheearthisround.主语从句
Itisonlylatelythathehashadafamilyhimself.强调句
Whatwasitthathewanted?
Idon’tknowwhatitwasthathewanted.强调句
Itwasinthehotelwherehestayedthatwediscussedtheseriousproblem强调句
8.连词whether和if有时可以互换,但注意下列情况
总体规律:
whether的使用范围比if要广
(1)后面出现ornot时,用whether
Iwanttoknowwhetherornottheywillcome.
(2)连接词后直接加不定式,不能用if只能用whether
Hedoesn’tknowwhethertostayornot.
(3)whether可以防句首,而if不能
Whetherhewillcome,Iamnotsure.
ItisuncertainifhewillleaveforBeijingtomorrow.(√)(if可引导主语从句)
IfhewillleaveforBeijingtomorrowisuncertain.(×)
WhetherhewillleaveforBeijingtomorrowisuncertain.(√)
(4)表语从句中只能用whether
Thedoubtiswhetherhewillcome.
(5)同位语中只能用whether
Thequestionwhetherheishonestisnotsettled.
(6)介宾从句中只能用whether;动宾从句则if和whether都可用
Hewasinterestedinwhetherhesawherthere.
Idon’tknowif/whetherheisathome.
