主语从句的用法
一、主语从句在复合句中作主语,它可
以位于句首,但常见的主语从句多放在
句末,句首则用形式主语it。
1.Thattheearthisroundistrue.
=Itistruethattheearthisround
2.Whetherhewillcomehasn’tbeendecided.
=Ithasn’tbeendecidedwhetherhewillcome.
注意:
连词that,whether在从句中不担任 句子成分,只起连接作用,不能省略 (注:
if不可用来引导主语从句)
WhenhewillgotoAmericaisnotyetfixed.
(ItisnotyetfixedwhenhewillgotoAmerica.)
Whoeverleavestheroomlastshouldclosethedoor.
Whateverwedomustbeintheinterestsofthepeople.
3.常见的it作形式主语的结构
1)Itisafactthathewonthematch.
2)ItisnecessarythatwedostudytheEnglish.
3)Itisknowntoallthatlighttravelsinstraightlines.
4)Itseemedthathewouldcomehere
基本句型结构
常用词语
Itis+名词+that从句
Itisafact/ashame/apity/nowonder/
goodnews/…that…
Itis+形容词+that从句
Itisnecessary/strange/important/
possible/likely/…that…这类主语从
句中,谓语动词常为(should)+动词原形
Itis+过去分词+that从句
Itissaid/reported/decided/known/
…that…
It+不及物动词+that从句
Itseemed/happened/doesn’t
matter/hasturnedout/…that
二、it作形式主语和it引导强调句的比较
it作形式主语代替主语从句,主要是为了平衡句子结构,主语从句的连接词有变化。
而it引导的强调句则是对句子某一部分进行强调,无论强调的是什么成分,都可用连词that。
被强调部分指人是也可用who/whom。
例如:
uItisapitythatyoudidn’tgotoseethefilm.
uItdoesn’tinterestmewhetheryousucceedornot.
uItisinthemorningthatthemurdertookplace.
uItisJohnthatbrokethewindow.
宾语从句的用法
句子结构:
主句+连接词(引导词)+宾语从句
1.Webelieve(that)heishonest.
2.Doyouknowwhathesaidjustnow?
3.Idon’trememberwhenwearrived
4.Lilywantedtoknowif/whetherhergrandmalikedthehandbag.
5.weshouldthinkofhowwecandomoreforothers
在think,believe,suppose,expect等动词之后,宾语从句中谓语的否定常转移到主句的谓语上。
Idon’tbelievehewillgo.
Wedon’texpectheiscoming.
Idon’tthinkhecandoit,canhe?
You/Theydon’tthinkhecandoit,dothey?
在接复合宾语的句子中,为了保持句子平衡,用it作形式宾语,将从句放于句尾,常接复合宾语的动词有:
make,find,see,hear,feel,think...
Ithinkitnecessarythatwetakeplentyofhotwatereveryday.
I
think
it
a
pity
to
waste
the
food
表语从句的用法
在复合句中用作表语的从句是表语从句,引导表语从句的关联词与引导主语从句的关联词大致一样,表语从句位于连系动词后,有时用asif引导。
其基本结构为:
主语+系动词+that从句。
That’swhatweshoulddo.
That’swhyIwanttoseeyou.
ThereasonformyabsencewasthatIwasill.
1.be,seem,look等动词后均可跟表语从句:
Mysuggestionisthatweshouldgoshopping.
Itseemsthatitisgoingtorain
2.asif,because也可引导表语从句。
Itlooksasifit’sgoingtorain.
ItwasbecauseIgotuplate.
3.在非正式文体中,引导表语从句的that可以省略。
如:
Thetroubleis(that)heisill
在表语从句中,当reason做主语时, 引导词只能用that,不能用because,如:
他迟到的原因是因为他没有赶上早班车。
Thereasonwhyhewaslatewasthathedidn’tcatchtheearlybus.
同位语从句的用法
在句中起同位语的作用.一般放在名词fact,news,idea,promise,thought,suggestion,truth,hope,problem,information,belief,doubt,questiondreamadvice,proofdecision等之后,用以说明或解释前面的名词.
1.Thequestionwhetherweneedmoretimetodotheworkhasnotbeendiscussed.
2.Ihavenoideawhentheywillgo.
3.Thesuggestionthattheplan(should)bedelayedwillbediscussedtomorrow.
名词suggestion,advice.order等词后的同位语从句的谓语动词要用should+动词原形,should可省略.
同位语从句有时被别的词把它和名词隔开:
ThestorygoesthatWilliamTellkilled
thekingwithanarrow.
Wordcamethattheirteamhadwon
九大热点问题
1..同位语从句与定语从句的区别
1).Thenewsthattheplanewouldtakeoffontimemadeeverybodyhappy.
2).Thenewsthatisspreadingaroundtheairportisthataheavystormiscoming.
3).Thesuggestionthatstudentsshouldlearnsomethingpracticalisworthconsidering.
4).Thesuggestionthattheyareconsideringisthatstudentsshouldlearnsomethingpractical
同位语从句与定语从句的不同之处
从句的作用不同:
同位语从句用来进一步
说明前面名词的内容;
定语从句用来修饰、
限定前面的名词(相当于一个定语)。
e.g.Thenewsthatourteamhaswonthefinalmatch
isencouraging.(从句说明“消息”的内容:
我们队取得了决赛胜利。
)
Thenewsthatyoutoldusisreallyencouraging.
(从句对“消息”加以限定:
是你告诉我们的,而非来自其他渠道。
但消息是何内容却不得而知。
引导从句的关联词that的功能不同:
that引导同位语从句时是一个纯连词,不充当任何成分;
而引导定语从句的that是关系代词,既指代先行词又须在从句中充当成分。
e.g.1)DadmadeapromisethathewouldbuymeCDplayerifIpassedtheEnglishtest.(that不充当任何成分)
2)Dadmadeapromisethatexcitedallhischildren.
(that指代promise,又在从句中充当主语。
Choosethebestanswer
