名词性从句讲解课件

名词性从句讲解课件名词性从句在句子中起名词作用的句子叫名词性从句(NounClauses）。名词性从句的功能相当于名词词组,它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能，名词性从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。名词性从句在功能上相当于名词Hisjobisimportant.Whathedoesisimportant.SubjectThisishisjob.Thisiswhathedoeseveryday.

单个宾语从句中的that可省略that不可省略的情况：

a.主语从句

b.表语从句

c.同位语从句

d.用it做形式宾语的宾语从句

e.并列的宾语从句中的后几个从句的

引导词that不能省略that/(that)1.Idon’tthink________sheiscoming.

2.Itisapity________hehasmadesuchamistake.

3.Thereasonis_________heiscareless.

4.Thenews________ourteamwonthematch

(that)thatthatthatthat(that)thatb.wh-(how)wordsWhytheyhavenotleftyetisunclear.Pollydidn’tknowwhichwayshewouldgo.TheproblemishowPollyisgoingtofindusinthecrowd.Thisisaquestionwhosebookitis.连接代词和副词的选用主要根据名词性从句中的具体意义连接代词：what,whatever,who,whoever,whom,whose,which连接副词：when,where,how,why这些连接词不仅起到连接作用，同时也是从句的一个组成部分。我们何时举行运动会还没有决定。

________weshallholdoursportsmeetingis

notdecided.

我不知道昨天谁打破了玻璃。

Idon’tknow_________broketheglassyesterday.

我不知道他长的什么样子。

Ihavenoidea_________helookslike.

这就是我忘记眼镜的地方。

Thisis_________Ileftmyglasses.

Whenwhowhatwherec.if/whether(不充当从句的任何成分）1.Iaskedherif/whethershehadabike.

2.Whetherwewillholdapartyintheopenair

tomorrowdependsontheweather.

3.Thequestioniswhetherheshoulddoit.

4.Thedoctorcanhardlyanswerthequestion

whethertheoldmanwillrecoversoon.5.We’reworriedaboutwhetherheissafe.

6.WediscussedwhetherweshouldclosetheshoponSunday.7.Idon’tknowwhethertogo.8.Idon’tknowwhetherornotheiswell.

if和whether的选用不能使用if的情况：

a.主语从句

b.表语从句

c.同位语从句

e.介词后的宾语从句

f.动词discuss引导的宾语从句g.whethertodo做动词宾语不能用iftodo.

h.whetherornot连在一起引导宾语从句时不用if.Theweatherwillnotclearupuntilnextweek.Itisbadnewsforus.→Itisbadnewsforusthattheweatherwillnotclearupuntilnextweek.2.Doanimalshavethesamesensesashumans.Ioftenwonder.→Ioftenwonderwhetheranimalshavethesamesensesashumans.3.I’msurethatheishonest.I’mnotsurewhether/ifheishonest.Idoubt_____________heishonest.Ihavenodoubt___________heishonest.whether/ifthat4.Nooneknowswhether/ifitwillbefinetomorrowandwhether/ifhewillcometowork.hesaidthathelikedrainandthathewouldn’tuseanumbrellawhenitwasraining.that与whether/if的用法区别whether(if)表示“是否”，而that却不表示任何意义。that表示一种肯定、明确的概念，而whether(if)则表示一种不肯定、不明确的概念。当that/if/whether引导的名词性从句是由and或but连接的两个并列分句时，则在and或but后还需要用that/if/whether引导，不可省略。二、

名词性从句中使用陈述句语序他是怎么成功的仍然是个谜。

Howwashesuccessfulisstillapuzzle.()

Howhewassuccessfulisstillapuzzle.()你能告诉我他住在什么地方吗？

Couldyoutellmewherehelives?()

Couldyoutellmewheredoeshelive?()WRRwHomework:1.P92C1&C22.kkl:Period5grammar(1)Period10:close&readingcomprehensionthat和what的选用that和what都可引导所有的名词从句。

但是，what除起连接作用外，还在名

词性从句中充当成分，可做从句的主

语、宾语、或表语。而that在名词性从

句中不充当任何成分，只起连接作用。that/what1.______hewantsisabook.2.______hewantstogothereisobvious.

3.Theresultis______wewonthegame.

4.Thisis_____wewanttoknow.

5.Is_____hetoldustrue?

6.Weshouldpayattentionto______theteacheris

saying.

7.Ihavenodoubt_____hewillcome.

8.Ihavenoidea_____hedidthatafternoon.

WhatThatthatwhatwhatwhatthatwhat三、同位语从句的引导和辨别1.同位语从句的格式：n.+连接词+从句

2.能接同位语从句的名词有：fact、idea,news,

information,order,belief,suggestion,advice等抽象名词。

3.连接词通常是that,也可根据含义选用

whether,what,when,where等来引导同位语从句。1.Ihavenoidea_________hecomesfrom.

2.Hecan’tanswerthequestion________he

gotthemoney.

3.Hegaveusmanysuggestions________we

shouldgetupearlierandtakemoreexercise.

4.Ihavenodoubt________hewillwin.

5.Ihavesomedoubt________hewillwin.that/whether/where/howwherehowthatthatwhether同位语从句和定语从句的区别1.定语从句是先行词的修饰语，它不涉及先行词的

具体内容。定语从句中that不但起连接作用，而且

在定语从句中充当一个句子成分，充当从句的宾语成分

时可省略。2.同位语从句对中心词的内容作进一步的解释和说明，

表明中心词的具体内容。引导同位语从句的that

在同位语从句中不做任何成分,只起连接作用,无具体

含义,且不可省略.1.Weexpressedthehopethattheyhadexpressed.

2.Weexpressedthehopethattheywouldcome

toChinaagain.1.Theinformationhasbeenannouncedthatmoremiddleschoolgraduateswillbeadmittedintouniversity.

2.Theinformationthatherevealedatthemeetingisofgreatvalue.AttributiveorAppositive

ATAPAPAT名词demand,suggestion,proposal,advice

等词后的同位语从句的语气要用虚拟语气,

结构为should+do,should可省略HegavemeasuggestionthatI(should)

becalmnow.宾语从句的时态呼应1.如果主句时态是现在时或将来时,从句谓语

可根据句意需要而选用任一种时态.

a.他相信他的梦想总有一天会实现的.

Hebelieves_________________________.

b.请告诉我你昨天这个时候在干什么.

Pleasetellme_________________________.hisdreamwillcometruesomedaywhatyouweredoingatthistimeyesterday2.如果主句谓语是过去时,从句谓语动词一般用过去的

某种时态,但从句表达的是客观事实、真理、自然规

律等时，从句谓语通常用一般现在时。

他告诉我他正在为考试做准备。

Hetoldme______________________.

他说他已离开家乡十年了。

Hetoldme______________________.

老师告诉我们光是沿直线运行的。
