2024年中考英语三轮冲刺：宾语从句（学生版版）

主句和从句主@Idon'tknowwhattodonext.

考查的主要形式：单项填空、完形填空、短文填空和完成句子，阅读理解和书面表达因此学生要熟练

掌握宾语从句的用法。

考赢

考向一：宾语从句的种类

1.that引导的宾语从句。that只有语法作用，没有实在的意义，在口语和非正式文体中可以省略。

Shedoesn'tknow(that)sheisseriouslyill.

2.由连接代词：who,whom,whose,what,which

连接副词when,where,why,how引导的宾语从句。

Doyouknowwho(whom)theyarewaitingfor?

Idon'tknowwhythetrainislate.

3.由if或whether引导的宾语从句。if和whether在句中的意思是“是否

Heaskedmewhether(if)Icouldhelphim.

考向二：宾语从句的语序

宾语从句的语序应为陈述句的语序，即按照主语、谓语的顺序。

1.陈述句变为宾语从句，语序不变。

Heisanhonestboy.Theteachersaid.

—Theteachersaid(that)hewasanhonestboy.

2.一般疑问句和特殊疑问句变为宾语从句，语序变为陈述语序。

Doesheworkhard?Iwonder.

—>Iwonderif/whetherheworkshard.

考向三：宾语从句主句与从句时态一致的问题。

1.主现从不受限制

Hehastoldmethathe511leaveforNewYorktomorrrow.

CanyoutellmehowIcangettotherailwaystation?

2.主过从过

Hetoldmethathewouldtakepartinthehighjump.

HeaskedifyouhadwrittentoPeter.

3.客观事实或真理，用一般现在时态。

OurteachersaidthatJanuaryisthefirstmonthoftheyear.

Scientistshaveprovedthattheearthturnsaroundthesun.

【奇思巧计】

宾语从句须注意,几点事项应牢记。一是关键引导词，不同句子词相异。

陈述句子用that；一般疑问是否(if,whether)

特殊问句更好办,引导还用疑问词。

二是时态常变化,主句不同从句异。

主句若为现在时,从句时态应看意；

主句若为过去时,从句时态向前移。

三是语序要记清,从句永保陈述序。

that引导的宾语从句

that引导的宾语从句由陈述句转化而来，故从句的语序不变。that作连接代词，无意义，在句中不作任何

成分，通常可以省略。

that引导的宾语从句的用法

1.位置：that引导的宾语从句通常放在主句谓语动词(及物动词)、介词或形容词之后。

①作及物动词：

如：say,think,tell,know,hear,see,hope,wish,remember,forget等的宾语。

ShesaysthatshewillhelpmelearnEnglishthisevening.

②作介词的宾语：连词that引导的名词性从句很少作介词的宾语，只用在except,but,in之后。如：

Heisagoodboyexceptthatheiscareless.

③作“be+形容词”结构的宾语。

如：sure,glad,certain,pleased,sorry,happy,afraid等，连词that可省略。

I'mhappy(that)Ipassedtheexam.

3.时态：主句是一般现在时，从句可根据具体情况选用适当的时态；

主句是一般过去时，从句中也必须用过去的某种时态。

Hesaysthathewantstoseehimassoonaspossible.

Hesaidthathewantedtoseehimassoonaspossible.

【特别提醒】

当主句是一般过去时，而宾语从句的内容表示的是客观真理、事实、科学原理、自然现象、名言警句、格

言、谚语等时，此时宾语从句用一般现在时，这些情况下不受主句时态的限制。

Theteachertoldusthattheearthgoesroundthesun.

3.引导词that可以省略的几种情况：

引导宾语从句的连词that通常可以省略：

Ihoped(that)Iwould/shouldsucceed.

Hethought(that)theywouldgivehimavisa.

Everybodyknows(that)moneydoesn'tgrowontrees.

【注意】that引导的宾语从句可位于句首，此时that不可省略：

ThatsheisagoodgirlIknow.

4.引导词that不能省略的几种情况：

①从句的主语是that时

Weknowthatisaninterestingfilm.

②and连接的两个表示陈述意义的宾语从句并列时，

第一个从句的连词that,但第二个从句的连词that一般不可以省略。

Hetoldme(that)theycouldnotdecidewhattodoandthattheyaskedmyadvice.

③that引导的宾语从句作介词宾语时

Iknownothingabouthimexceptthatheisfromthesouth.

对他我一无所知，只知道他是南方人。

5.宾语从句的否定转移。

在think,believe,suppose,expect等动词后的宾语从句，

当主句的主语是第一人称时，谓语尽管是否定的意思，却不用否定形式

而将think等动词变为否定形式，英语称这种现象为否定转移。

Idon'tthinkhecancomethisevening.

Hethinkswearenotintheclassroomnow.

【特别警示】

含有“否定转移”现象的句子，主句的主语必须是第一人称，

此时，变成反意疑问句，附加问句要由从句来决定；

如果主句的主语是其他人称，附加问句要由主句来决定。

Idon'tthinkheisright,ishe?

HethinksIcancome,doesn'the?

6.如果宾语从句中含有否定意义的副词或形容词。

hardly,never,seldom,no,few,little等，其反意疑问句要用肯定形式。如:

Wefindthatheseldomgoestovisithismother,doeshe?

7.that引导的宾语从句变成被动语态时，只变主句，不变从句。

Itissaidthat...（据说...）；

Itisknownthat...（众所周知...）；

Itisreportedthat…（据报告...）等当作固定句式来运用。

ItissaidthatheisfromCanada.

疑问词引导的宾语从句

由疑问词when,who,what,where,whatever,how,which,why等引导。

宾语从句的词序一律用陈述句的词序，即“主语+谓语”词序。

①带有系动词be（is,am,are,was,were）的特殊疑问句。

主句宾语从句

DoyouknowhowoldLizis?你知道兹几岁吗?

IknowhowoldLizis.我知道莉兹几岁。

Idon'tknowhowoldLizis.我不知道莉兹几岁。

②带有（情态）助动词is/am/are/have/has/can/should等的特殊疑问句

WhenisAnngoingtoIran?

—DoyouknowwhenAnnisgoingtoIran?

—Idon'tknowwhenAnnisgoingtoIran.

WhatshouldIdo?

一CanyoutellmewhatIshoulddo?

一PleasetellmewhatIshoulddo.

③带有助动词do/does/did的特殊疑问句。

WheredidIputmyweddingring?

—DoyouknowwhereIputmyweddingring?

WhatdoesSuethinkaboutLulu?

一DoyouknowwhatSuethinksaboutLulu?

注意：

(1)由于宾语从句要求陈述句语序，故而在从句中它变成了陈述语序。

Wheredidyougoyesterday?

一Pleasetellmewhereyouwentyesterday.

(2)当疑问代词what、who在特殊疑问句中作主语时，该特殊疑问句本身就是陈述句语序，所以当该句用

来作宾语时，语序不需要调整。

Whafswrongwithyou?

—Heaskedthegirlwhatwaswrongwithher.

Whathashappenedtohim?

一Wewanttoknowwhathashappenedtohim.

if/whether引导的宾语从句

当从句部分是一般疑问句或选择疑问句时，常用if或whether引导宾语从句，

if/whether意为“是否"。

说明对陈述的事物不明确或不清楚。

常用在see,ask,say,learn,tell,wonder,doubt,

findout,beuncertain/doubtful/benotknown

Alicewantstoknowif/whethershehaspassedtheexam.

Iwanttoknowif(whether)helivesthere.

【拓展】

以下几种情况下，只能用whether。

1.句中有ornot时用whether

Idon'tknowwhetherheiswrongorsheiswrong.

IwillwritetoyouwhetherornotIcancome/whetherIcancomeornot.

2.在动词不定式之前只能用whethero

Hedosen'tknowwhethertogoornot.

Whethertogoorstayisstillaquestion.

3.在介词之后只能用whether

Successdependsonwhetherwemakeenougheffort.

IworryaboutwhetherIhurtherfeelings.

4.置于句首表示强调时

Whetherheissingle,Idon'tknow.

Whetherthisistrue,Ican'tsay.

5.在某些动词（如discuss,decide）之后

Wediscussedwhetherweshouldgotherebyplane.

Wediscussedwhetherweshouldholdameeting.

5.在引导否定概念宾语从句时

HeaskedmeifIhadn'tfinishedmywork.

注意：doubt否定句用that引导。因为don'tdoubt意为相信，不怀疑，if是否表示疑虑。
