专题08名词性从句
一:知识讲解
根据高二学业水平考试的要求,名词性从句是必考且重要的语法点。它相当于一个名词,在复合句中
能充当主语、宾语、表语和同位语。
以下是对名词性从句考点的系统归纳,以表格形式呈现,并配有例句和重难点分析。
高中学考名词性从句考点归纳总结表
名词性从句主要由三类连接词引导,其核心是语序必须用陈述语序。
从句连接词功能与说典型例句考查重点与难点
类型明
主语that,在句中作1.Thathewillsucceediscertain.难点
从句whether,主语。(that不充当成分,只引导)1:形式主语it:为避免“头重脚轻”,
连接代词,that只起2.Whetherwewillgodependson常用Itis+adj./n.+that从句结构。
连接副词连接作theweather.(whether意为“是否”)e.g.Itiscertainthathewillsucceed.
用,无意3.Whatweneedismoretime.难点2:
义且不充(what在从句中作need的宾语)that在主语从句中不能省略。
当成分。4.Wherehehasgoneisunknown.
(where在从句中作地点状语)
宾语that,在句中作1.Ithink(that)youareright.(that核心考点1:三要素:连接词、陈述语
从句if/whether,动词或介可省略)序、时态呼应。
连接代词,词的宾2.Iwonderif/whethershewill核心考点2:ifvswhether:
连接副词语。come.(在宾语从句中,if≈whether)-介词后只能用whether。(e.g.It
3.Canyoutellmewhoisondutydependsonwhether...)
today?(who在从句中作主语)-后接ornot时,多用whether。(e.g.I
4.HetoldmewhereIcouldfinddon'tknowwhetherornotheisready.)
thebook.(where作地点状语)核心考点3:时态:主句是过去时,从
5.Iaminterestedinwhatyouhave句需用相应的过去时态(客观真理除
said.(作介词宾语)外)。
表语that,在系动词1.Thefactisthatwehavelostthe重点:连接词that在表语从句中通常
从句whether,(be,game.不能省略。
asif,连seem,2.Thequestioniswhetherwecan难点:区分that引导的表语从句和强
接代词,remaingetthereontime.调句Itis...that...。
连接副词等)后作3.ThatiswhyIwaslate.(why作
表语。原因状语)
4.Helooksasifhehadseena
ghost.(asif引导,表“好像”)
同位that,跟在抽象1.Thenewsthatourteamhad最大难点:同位语从句vs定语从句:
语从whether名词(fact,wonmadeushappy.(that解释-引导词that:在同位语从句中,that
句news,news的内容,不充当成分)是连词,不充当任何句子成分,只起
idea,hope,2.Ihavenoideawhetherhewill连接作用。在定语从句中,that是关
belief等)comeornot.系代词,必须充当主语或宾语。
后,解释-意义:同位语从句是解释内容(=);
说明该名定语从句是修饰限定(…的)。
词的具体对比:
内容。-Theideathatheproposedisgood.(定
语从句,that作proposed的宾语,指“他
提出的那个想法”)
-Theideathatweshouldgocampingis
good.(同位语从句,that不充当成分,
指“我们应该去野营”这个想法本身)
连接词的选择(解题关键)
这是考查名词性从句的核心。选择哪个连接词,取决于从句本身缺少什么成分。
解题步骤:
找到从句部分。
分析从句的句子结构是否完整。
不缺成分(主谓宾齐全):用that(表陈述事实)或whether/if(表“是否”)。
缺主语、宾语、表语(指“物”):用what;(指“人”):用who。
缺定语(表示“谁的”):用whose。
缺状语:
试卷第2页,共7页
缺时间状语:用when
缺地点状语:用where
缺原因状语:用why
缺方式状语:用how
陈述语序
名词性从句一律使用陈述句语序(主语在前,谓语在后),永远不能用疑问句倒装语序。
错误:Idon'tknowwhereisthelibrary.
正确:Idon'tknowwherethelibraryis.
时态呼应
如果主句谓语是过去时,则宾语从句的谓语也要用相应的过去时态(一般过去时、过去进行时、过去
将来时、过去完成时等)。
例外:如果从句表示的是客观真理或自然现象,则时态不变,仍用一般现在时。
e.g.Theteachertoldusthatlighttravelsfasterthansound.
if与whether的区别
学考中,以下几点是高频考点,必须牢记只能用whether的情况:
正式语境中,引导主语从句置于句首时。
引导表语从句和同位语从句时。
作介词宾语时。
后直接接ornot时。
备考建议:
1.分析成分:遇到名词性从句的题目,首先分析从句部分是否缺少成分,这是选择连接词的王道。
2.熟记规则:牢记只能用whether的四种情况以及时态呼应的规则。
3.对比辨析:重点理解和练习同位语从句和定语从句的区别,这是最大的难点。
4.检查语序:写完句子后,一定要检查从句部分是否是陈述语序。
