一、核心定义
(一)名词性从句的 4 种类型及本质
本质:在句中充当名词的作用(作主语、宾语、表语、同位语),从句需用陈述语序,连接词决定从句逻辑。

当主句谓语动词是现在的某种时态时,宾语从句根据情况选用任意时态, 当主句谓语动词是过去的某种时态时,从句中谓语动词也要用过去范畴的时态,但若从句陈述的是真理或客观规律,不论主句是什么时态,其谓语的时态仍用一般现在时.

同位语从句与定语从句的区别
英语中一个名词或代词后所跟的从句要么是定语从句,要么是同位语从句.判断其根本依据是看这个名词或代词(先行词)在后边从句中是否充当句子成分,若不充当任何句子成分则是同位语从句;若充当句子成分则是定语从句.以下是几点区别方法。
1.意义的不同
同位语从句是用于说明所修饰名词的具体内容的,它与被修饰词语通常可以划等号(同位语从句和先行词可转化为表语从句);而定语从句是限定所修饰名词的。
We are glad at the news that he will come.
We are glad at the news that he told us.
2.从引导词的省略角度来看
同位语从句的所有引导词在任何情况下都不能省略。而定语从句的引导词在有些时候可以省略。如关系代词在限制性定语从句作宾语时可以省。
The suggestion (that) she has put forward is very good.
The suggestion that we clean the classroom by turns is very good.
The fact (that) we talked about is important.
The fact that he succeeded in the experiment pleased everybody.
3.从引导词的总类来看
what, how, whether等可引导同位语从句,但不引导定语从句。
4.从引导词的功能上的不同
①所有定语从句的引导词都是替代先行词,且必须在定语从句中充当一定的句子成分.而所有同位语从句的引导词都不替代其所修饰的名词,其中that, whether
只起引导作用,不充当任何句子成分.但疑问词引导的同位语从句要在此句中充当相应的句子成分.②疑问词引导的同位语从句表疑问,引导定语从句时不表疑问.③疑问词引导的同位语从句只是先行词具体内容的表述,并不替代其所修饰的名词。
5.被修饰词语的区别
同位语从句所修饰的名词比较有限,通常有hope, wish, idea, news, fact, promise, opinion, suggestion, truth等,而定语从句所修饰的名词则非常广泛.另外,when和where 引导定语从句时,通常只修饰表示时间和地点的名词,而它们引导同位语从句时却不一定;又如why引导定语从句,它通常只修饰名词the reason,而它引导同位语从句时则不一定。
They put forward the question where they could get the money.
This is the place where the accident happened.
I have no idea when they will come.
I’ll never forget the days when I lived there.
基本上可以说when 和where前面的名词若是表示时间、地点的名词, 则when和where引导的是定语从句,否则为同位语从句。
▲名词性从句引导词which与what的区别
要选which,需给出被选对象,若无被选对象则不能选which. what表泛指,不需给出被选对象.且what具有分身术,可分身为一个指人或指物的先行词(sb/sth)+关系代词(which/that/who/whom)所构成的定语从句.

连接词类别
代表词汇
语法功能
从属连词
that/if/whether
仅起连接作用(if/whether 表 “是否”)
连接代词
what/which/who/whom/whose
连接 + 在从句中作主语 / 宾语 / 定语
连接副词
when/where/why/how/how many/how much 等
连接 + 在从句中作状语
二、4 大核心易错点精析
易错点 1:连接词选择错误
错因分析
1. 混淆 “连接词是否作成分”:缺成分时误用从属连词(that/if),无缺成分时误用连接代词 / 副词;
2. 混淆 “是否” 表达:if 与 whether 的用法边界不清;
3. 固定搭配误用:如 reason 后表语从句误用 because,instead of 后误用 that 引导宾语从句。
【易错提醒】
误:I don’t know that he will come.(想表达 “是否”,无缺成分但需表疑问)
正:I don’t know whether/if he will come.
【解析】从句无缺成分,表 “是否” 时用 whether/if;若后接 or not,只能用 whether(I don’t know whether he will come or not)。
误:She asked me that I liked English.(想表达 “是否”,动词 ask 后需疑问语气)
正:She asked me if/whether I liked English.
【解析】ask、wonder、doubt 等表 “询问 / 怀疑” 的动词后,宾语从句表 “是否” 需用 if/whether,不用 that。
误:The reason why he was late is because he missed the bus.(固定搭配错误)
正:The reason why he was late is that he missed the bus.
【解析】reason 后接表语从句时,固定用 that 引导(The reason is that...),because 不可替代(because 引导原因状语从句)。
拓展延伸:whether 的 6 种特殊用法(if 无此功能)
1. 作介词宾语:It depends on whether we have enough time.(不可用 if)
2. 引导主语从句放句首:Whether he will attend the meeting is uncertain.(不可用 if)
3. 接不定式:She hasn’t decided whether to go abroad.(不可用 if)
4. 与 or not 连用:I’m not sure whether he is right or not.(if 需改为 if...or not,不如 whether 简洁)
5. 引导表语从句:The question is whether we can finish the task.(不可用 if)
6. 引导同位语从句:There is some doubt whether they will succeed.(不可用 if)
易错点 2:宾语从句语序错误
错因分析
1. 受主句疑问语气影响,误将从句改为疑问句语序(助动词 / 情态动词提前);
2. 连接词为 what/who/which 等作主语时,误判为语序错误。
【易错提醒】
误:Could you tell me where is the nearest bank?(从句用了疑问语序)
正:Could you tell me where the nearest bank is?
【解析】宾语从句必须用 “连接词 + 陈述句语序”,助动词 is 需放在主语 the nearest bank 后。
误:I don’t know what did he say at the meeting.(助动词 did 提前,语序错误
正:I don’t know what he said at the meeting.
【解析】从句主语是 he,谓语动词 said 需用过去式,遵循 “主语 + 谓语” 的陈述语序。
避坑技巧:语序判断三步法
1. 找到从句的连接词;
2. 识别从句的主语(连接词作主语时,连接词 = 主语);
3. 确保 “主语在前,谓语在后”,助动词 / 情态动词不提前。
易错点 3:that 的省略与不可省略混淆
错因分析
1. 过度省略:在需保留 that 的语境中误删,导致句子歧义或语法错误;
2. 多余添加:在可省略 that 的语境中冗余使用,显得累赘。
不可省略 that 的 5 种关键情况(必记)
1. 主语从句放句首时:That she refused the offer surprised all of us.(不可省略)拓展:用 it 作形式主语时,that 可省略:It surprised all of us (that) she refused the offer.
2. 宾语从句有多个并列分句时(第二个及以后 that 需保留):错误:He said he would come and he would bring a gift.(第二个 that 省略,易歧义)正确:He said that he would come and that he would bring a gift.
3. 表语从句中:The fact is that we have run out of time.(不可省略)
4. 同位语从句中:We heard the news that our team won the game.(不可省略)
5. 宾语从句前有插入语时:He said, to my surprise, that he had quit his job.(that 不可省略)
可省略 that 的 3 种情况
1. 宾语从句放及物动词后(常用动词:say/tell/think/believe 等):She told me (that) she would visit me next week.
2. 用 it 作形式宾语时:I find it necessary (that) we should practice more.
3. 宾语从句较短且逻辑清晰时:He thinks (that) English is easy to learn.
易错点 4:同位语从句与定语从句混淆
错因分析:两者均位于名词后,误将解释名词 “内容” 的同位语从句当作修饰名词的定语从句,连接词误用 which/that。
核心区分技巧
特征
同位语从句
定语从句
连接词
常用 that(不可省略),无 which
可用 that/which(作成分时可省略)
从句功能
解释名词的 “具体内容”(名词与从句等价)
修饰名词的 “特征 / 范围”(限定名词)
that 的作用
无词义,不作成分
有指代意义(指代先行词),作主语 / 宾语
典型例句对比
1. 同位语从句:We were excited at the news that our team won the championship.
【解析】从句 “our team won the championship” 是 news 的具体内容,that 无意义、不作成分,不可改为 which。
2. 定语从句:We were excited at the news that/which he told us yesterday.
【解析】从句 “he told us yesterday” 修饰 news(限定 “他昨天告诉我们的消息”),that/which 指代 news,作 told 的宾语,可省略。
拓展:常接同位语从句的抽象名词
fact(事实)、news(消息)、idea(想法)、promise(承诺)、doubt(怀疑)、suggestion(建议)、belief(信念)、truth(真相)等。
三、3 大避坑点技巧总结(精准突破易错点)
避坑点 1:“成分分析法” 快速选连接词(解决 80% 连接词错误)
步骤:
1. 确定从句类型(主 / 宾 / 表 / 同位语从句);
2. 分析从句内部是否缺少成分(主语 / 宾语 / 定语 / 状语);
3. 匹配连接词:
4. 缺主语 / 宾语 / 定语→连接代词(what/which/who 等);
5. 缺状语(时间 / 地点 / 原因 / 方式)→连接副词(when/where/why 等);
6. 无缺成分→从属连词(that/if/whether),表 “是否” 用 if/whether,否则用 that。
实例应用:
1. ______ he will go to Beijing depends on his parents’ decision.(主语从句,无缺成分,表 “是否”→Whether)
2. I don’t know ______ he needs.(宾语从句,缺宾语→what)
3. The problem is ______ we can get enough money.(表语从句,无缺成分,表 “是否”→whether)
避坑点 2:“语序铁律” 兜底(解决语序错误)
核心规则:所有名词性从句,无论主句是否为疑问语气,从句必须用 “连接词 + 主语 + 谓语” 的陈述语序;连接词(what/who/which 等)在从句中作主语时,看似 “疑问语序” 实则为陈述语序,无需调整。
【易错提醒】
误:Do you know when will the train arrive?(从句用疑问语序)
正:Do you know when the train will arrive?(连接词 when + 主语 the train + 谓语 will arrive)
正:Who will be our monitor hasn’t been decided yet.(who 作从句主语,语序正确)
【解析】从句主语是 he,谓语动词 said 需用过去式,遵循 “主语 + 谓语” 的陈述语序。
避坑点 3:“固定搭配 + 语境匹配” 双重验证(解决细节错误)
1. 固定搭配清单(必记):
The reason is that...(原因是……)
It is a pity/shame/necessary that...(形式主语从句,that 不可省略)
I doubt if/whether...(我怀疑是否……)
I’m sure/certain that...(我确定……)
depend on/insist on+whether(不可用 if)
2. 语境匹配原则:
表 “不确定 / 选择”→用 whether/if;
表 “具体内容 / 事实”→用 that;
表 “时间 / 地点 / 原因 / 方式”→用对应的连接副词。
三层必刷:巩固提升+能力培优+创新题型
一、巩固提升练(基础小题)
(一) 单句改错。

2、 语法填空。
(一)
(23-24高二上·浙江湖州·期中)阅读下面材料,在空白处填入适当内容(1个单词)或括号内单词的正确形式。
There are currently over 3, 000 endangered languages in the world on the edge of extinction. And languages and dialects are dying at 1 alarming rate. According to National Geographic, one language disappears from the earth every 14 days, and few leave any recognizable marks. The least spoken languages in the world tend to be spoken only by a few elders of small 2 (community).

In this landscape of amazing loss, institutions and projects are trying to save 6 is left. The Endangered Languages Documentation Programme 7 (found) in 2002 with the aim of preserving languages threatened by extinction.

【答案】
1.an 2.communities 3.who/that 4.from 5.making 6.what 7.was founded 8.developed 9.to help 10.simply
【导语】本文是一篇说明文。主要介绍了很多语言和方言正在濒临灭绝,所以濒危语言文献项目成立于2002年,旨在保护濒临灭绝的语言。
1.考查冠词。句意:语言和方言正在以惊人的速度消亡。分析句子结构可知,此处考查固定搭配:at a rate意为“以……的速度”,空后是alarming,为原因音素开头,所以应该用an。故填an。
2.考查名词。句意:世界上说得最少的语言往往只被少数小社区的长者说。分析句子结构可知,空前是形容词small,所以空处应填名词,community意为“社区”,为可数名词,根据空前的a few可知,应该用复数形式。故填communities。
3.考查定语从句关系词。句意:对于那些试图在全球经济中立足的人来说,学习一门即将消亡的语言很少有吸引力,所以年轻一代通常不会从父母或祖父母那里学习这些语言。分析句子结构可知,空处引导定语从句,从句缺少主语,应该用关系代词,先行词为people,指人,所以应该用who或者that引导。故填who或者that。
4.考查介词。句意:对于那些试图在全球经济中立足的人来说,学习一门即将消亡的语言很少有吸引力,所以年轻一代通常不会从父母或祖父母那里学习这些语言。分析句子结构可知,此处考查固定搭配:learn sth. from sb.意为“向某人学某事”。故填from。
5.考查非谓语动词。句意:这些濒临灭绝的语言大多也缺乏书写系统,这使得保存它们成为更大的挑战。分析句子结构可知,本句已有谓语动词lack,所以make应该用非谓语动词形式,其中“使得保存它们成为更大的挑战”,表示正在进行的动作,所以此处应该用现在分词作结果状语。故填making。
6.考查宾语从句连接词。句意:在这种损失惊人的情况下,机构和项目正试图拯救剩下的东西。分析句子机构可知,空处引导的是宾语从句,从句中缺少主语,所以应该用连接代词引导,根据句意,此处指物,应该用what引导。故填what。
7.考查动词时态和语态。句意:濒危语言文献项目成立于2002年,旨在保护濒临灭绝的语言。分析句子结构可知,本句缺少谓语动词,所以found作谓语,主语是The Endangered Languages Documentation Programme ,为第三人称单数,同时两者间是被动关系,所以应该用被动语态,再根据时间状语in 2002,可知应该用一般过去时。故填was founded。
8.考查非谓语动词。句意:它不仅资助学者开发的个别项目,而且在伦敦和世界各地提供培训,帮助准备研究工作所需的方法。分析句子结构可知,本句已有谓语动词funds,所以develop应该用非谓语形式,根据空后的by表“被”之意,所以应该用过去分词表被动。故填developed。
9.考查非谓语动词。句意:它不仅资助学者开发的个别项目,而且在伦敦和世界各地提供培训,帮助准备研究工作所需的方法。分析句子结构可知,本句已有谓语动词 provides,所以help应该用非谓语形式,此处应该用不定式,作目的状语。故填to help。
10.考查副词。句意:记录语言的目的一定不是简单地把它们像蝴蝶一样钉在墙上。分析句子结构可知,空后是动词be,所以空处应填副词修饰动词,simple的副词形式是simply。

(23-24高二上·甘肃甘南·期中)阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式。
It is a special cross-country race. The competitors’ vehicles are made 11 fruits and vegetables like carrots, eggplants, grapefruits, pumpkins and oranges. They are the creations of pupils from the Shanghai World Foreign Language Primary School.
According to Chen You, the science class teacher, 12 (base) knowledge had been taught within 1 classes to students before they drew sketches and 13 (choose) vegetables to make a food car.
Although students were encouraged 14 (design) their cars together with parents, all the cars should be made in the class. After 15 (bring) piles of ingredients as well as tools the children began their innovation. Some cut the carrot slices to make them round, and some others assembled (组装) their car components together.
In addition to the 16 (compete), students are required to reflect on the 17 (difficulty) they encountered making their vehicles, and 18 things they have learned from the activity and the improvements they think the course can make.
19 touched the teachers most was the unity and friendship among the children. For example, although the contest was fierce (激烈的), students felt 20 (excite) for the champion car as if they themselves had stood out, and when a girl’s car fell apart their friends comforted her and helped reassemble the car.

11.考查介词。句意:参赛者的车辆由水果和蔬菜制成,如胡萝卜、茄子、葡萄柚、南瓜和橙子。固定搭配:be made of“由……组成”。故填of。
12.考查形容词作定语。句意:据科学班老师陈友介绍,在1节课的时间里,学生们先学习了基础知识,然后再画草图,选择蔬菜制作美食车。此处knowledge是名词,由形容词修饰,base的形容词是basic。故填basic。
13.考查一般过去时。句意:据科学班老师陈友介绍,在1节课的时间里,学生们先学习了基础知识,然后再画草图,选择蔬菜制作美食车。before引导的时间状语从句中动词choose与drew构成并列谓语。故填chose。
14.考查动词不定式。句意:虽然鼓励学生和家长一起设计自己的汽车,但所有的汽车都应该在课堂上制造。固定搭配:encourage sb. to do sth.“鼓励某人做某事”,其中动词不定式作宾语补足语,但该句是被动语态,句中动词不定式作主语补足语。故填to design。
15.考查动名词作宾语。句意:孩子们带来了成堆的食材和工具后,开始了他们的创新。句中after是介词,后面用动名词作宾语。故填bringing。
16.考查名词。句意:除了比赛之外,学生们还需要反思他们在制造车辆时遇到的困难,以及他们从活动中学到的东西,以及他们认为课程可以带来的改进。根据空前的the可知,此处用名词作宾语,所给词compete是动词,其名词是competition,此处表示这次比赛,用单数。故填competition。
17.考查名词复数。句意:除了比赛之外,学生们还需要反思他们在制造车辆时遇到的困难,以及他们从活动中学到的东西,以及他们认为课程可以带来的改进。此处用名词复数作宾语。故答案为difficulties。
18.考查并列连词。句意:除了比赛之外,学生们还需要反思他们在制造车辆时遇到的困难,他们从活动中学到的东西,以及他们认为课程可以带来的改进。分析句子可知,此处特指“在活动中学到的东西”,用定冠词修饰。故填the。
19.考查主语从句。句意:最让老师们感动的是孩子们之间的团结和友谊。该句主语是主语从句,主语从句缺少引导词,从句的谓语动词缺少主语,所填词要其双重作用,这里是连接代词what引导的主语从句,位于句首用大写。故填What。
20.考查情感形容词。句意:例如,虽然比赛很激烈,但学生们对冠军车感到很兴奋,就像他们自己脱颖而出一样。此处指“学生感到兴奋”,所以用动词excite的情感形容词excited。故填excited。

23.考查时态语态。句意:这里的景观是由公元10世纪移民到景迈山的布朗人的祖先以及傣族的祖先创造的,他们发现了野生茶树。分析句子可知,这里考查谓语动词,The landscape与create为被动关系,且这里时态应与后面保持一致,用一般过去时。故填was created。
24.考查介词。句意:在长期实践的基础上,当地人最终发展出了一种下层林木生长的技术。分析句子可知,这里考查on the basis of表“基于”,为固定搭配,且句首时首字母应大写。故填On。
25.考查副词。句意:在长期实践的基础上,当地人最终发展出了一种下层林木生长的技术。分析句子可知,此空应填副词作状语,修饰前面动词。故填eventually。
26.考查名词。句意:即为茶树的生长创造理想的光照条件,在不使用杀虫剂和化肥的情况下生产出优质的有机茶叶。分析句子可知,这里应填名词作介词后宾语,application表“运用”,为不可数名词,符合句意。故填application。

28.考查非谓语。句意:中国将加强对遗产地的监管,应对气候变化,引导当地社区参与保护,规范旅游业,确保老茶林突出的普遍价值得到持久传承。分析句子可知,此空应填不定式作宾补。故填to join。
29.考查非谓语。句意:在景迈山上,社区还维护着古老的治理体系来保护遗址,包括与茶祖有关的传统节日和仪式,茶祖是一种相信灵魂生活在森林中以及当地动植物中的信仰。be related to与……有关,此处用过去分词作后置定语。故填related。
30.考查同位语从句。句意:在景迈山上,社区还维护着古老的治理体系来保护遗址,包括与茶祖有关的传统节日和仪式,茶祖是一种相信灵魂生活在森林中以及当地动植物中的信仰。分析句子可知,这里考查同位语从句,而后面为完整句子,所以应用that引导该同位语从句。故填that。

寒假作业11 名词性从句(4大易错点+3大避坑点+易错通关练+高考真题+热点话题练习)(易错培优练)
一、核心定义
(一)名词性从句的 4 种类型及本质
本质:在句中充当名词的作用(作主语、宾语、表语、同位语),从句需用陈述语序,连接词决定从句逻辑。
(二)分类讲解
主语从句,在句子中作主语的句子叫主语从句。
1.由从属连词that, whether引导的主语从句:
▲that引导主语从句放在句首时,that不可省。
That light travels in straight line is known to all. (that不能省)
That he will succeed is certain. (that不能省)
That he is still alive is a wonder. (that不能省)
That the baby could speak made his parents very happy. (that不能省)
That she became an artist may have been due to her father’s influence. (that不能省)
▲whether引导的主语从句一般位于句首。也可用it作形式主语,将其后置,此时whether可换为if。 (if引导主语从句时,只能用it作形式主语,放在句首,而将if引导的主语从句放到句末。)
Whether she will come or not is still a question.

Whether we will hold a party in the open air tomorrow depends on the weather.
It was a problem whether they would support us.

主语从句的主谓一致问题
①单个主语从句作主语,谓语动词用单数;两个或两个以上主语从句并列作主语时,若表同一概念 / 事件,谓语用单数;若表不同概念,谓语用复数。
(同一概念):When and where the meeting will be held is not decided.(会议的时间和地点未确定,表同一事件)
(不同概念):When the project starts and who will lead it have been discussed.(项目何时启动、谁来领导,是两个不同问题)
②what引导的主语从句,谓语动词可由表语来决定。
What we need are women workers.
What we need is more time and money.
主语从句中的虚拟语气:其中在it’s natural/important/ necessary/strange that…结构中,主语从句常用should +do的虚拟语气(美语中省去should).
It was necessary that we (should) make everything ready ahead of time.
It is important that every pupil (should) be able to understand the rule of school.

7.宾语从句时态呼应原则
当主句谓语动词是现在的某种时态时,宾语从句根据情况选用任意时态, 当主句谓语动词是过去的某种时态时,从句中谓语动词也要用过去范畴的时态,但若从句陈述的是真理或客观规律,不论主句是什么时态,其谓语的时态仍用一般现在时.

My idea is that we (should) get more people to attend the conference.

同位语从句与定语从句的区别
英语中一个名词或代词后所跟的从句要么是定语从句,要么是同位语从句.判断其根本依据是看这个名词或代词(先行词)在后边从句中是否充当句子成分,若不充当任何句子成分则是同位语从句;若充当句子成分则是定语从句.以下是几点区别方法。
1.意义的不同
同位语从句是用于说明所修饰名词的具体内容的,它与被修饰词语通常可以划等号(同位语从句和先行词可转化为表语从句);而定语从句是限定所修饰名词的。
We are glad at the news that he will come.
We are glad at the news that he told us.
2.从引导词的省略角度来看
同位语从句的所有引导词在任何情况下都不能省略。而定语从句的引导词在有些时候可以省略。如关系代词在限制性定语从句作宾语时可以省。
The suggestion (that) she has put forward is very good.
The suggestion that we clean the classroom by turns is very good.
The fact (that) we talked about is important.
The fact that he succeeded in the experiment pleased everybody.
3.从引导词的总类来看
what, how, whether等可引导同位语从句,但不引导定语从句。
4.从引导词的功能上的不同
①所有定语从句的引导词都是替代先行词,且必须在定语从句中充当一定的句子成分.而所有同位语从句的引导词都不替代其所修饰的名词,其中that, whether
只起引导作用,不充当任何句子成分.但疑问词引导的同位语从句要在此句中充当相应的句子成分.②疑问词引导的同位语从句表疑问,引导定语从句时不表疑问.③疑问词引导的同位语从句只是先行词具体内容的表述,并不替代其所修饰的名词。
5.被修饰词语的区别
同位语从句所修饰的名词比较有限,通常有hope, wish, idea, news, fact, promise, opinion, suggestion, truth等,而定语从句所修饰的名词则非常广泛.另外,when和where 引导定语从句时,通常只修饰表示时间和地点的名词,而它们引导同位语从句时却不一定;又如why引导定语从句,它通常只修饰名词the reason,而它引导同位语从句时则不一定。
They put forward the question where they could get the money.
This is the place where the accident happened.
I have no idea when they will come.
I’ll never forget the days when I lived there.
基本上可以说when 和where前面的名词若是表示时间、地点的名词, 则when和where引导的是定语从句,否则为同位语从句。
▲名词性从句引导词which与what的区别
要选which,需给出被选对象,若无被选对象则不能选which. what表泛指,不需给出被选对象.且what具有分身术,可分身为一个指人或指物的先行词(sb/sth)+关系代词(which/that/who/whom)所构成的定语从句.

连接 + 在从句中作状语
二、4 大核心易错点精析
易错点 1:连接词选择错误
错因分析
1. 混淆 “连接词是否作成分”:缺成分时误用从属连词(that/if),无缺成分时误用连接代词 / 副词;
2. 混淆 “是否” 表达:if 与 whether 的用法边界不清;
3. 固定搭配误用:如 reason 后表语从句误用 because,instead of 后误用 that 引导宾语从句。
【易错提醒】
误:I don’t know that he will come.(想表达 “是否”,无缺成分但需表疑问)
正:I don’t know whether/if he will come.
【解析】从句无缺成分,表 “是否” 时用 whether/if;若后接 or not,只能用 whether(I don’t know whether he will come or not)。
误:She asked me that I liked English.(想表达 “是否”,动词 ask 后需疑问语气)
正:She asked me if/whether I liked English.
【解析】ask、wonder、doubt 等表 “询问 / 怀疑” 的动词后,宾语从句表 “是否” 需用 if/whether,不用 that。
误:The reason why he was late is because he missed the bus.(固定搭配错误)
正:The reason why he was late is that he missed the bus.
【解析】reason 后接表语从句时,固定用 that 引导(The reason is that...),because 不可替代(because 引导原因状语从句)。
拓展延伸:whether 的 6 种特殊用法(if 无此功能)
1. 作介词宾语:It depends on whether we have enough time.(不可用 if)
2. 引导主语从句放句首:Whether he will attend the meeting is uncertain.(不可用 if)
3. 接不定式:She hasn’t decided whether to go abroad.(不可用 if)
4. 与 or not 连用:I’m not sure whether he is right or not.(if 需改为 if...or not,不如 whether 简洁)
5. 引导表语从句:The question is whether we can finish the task.(不可用 if)
6. 引导同位语从句:There is some doubt whether they will succeed.(不可用 if)
易错点 2:宾语从句语序错误
错因分析
1. 受主句疑问语气影响,误将从句改为疑问句语序(助动词 / 情态动词提前);
2. 连接词为 what/who/which 等作主语时,误判为语序错误。
【易错提醒】
误:Could you tell me where is the nearest bank?(从句用了疑问语序)
正:Could you tell me where the nearest bank is?
【解析】宾语从句必须用 “连接词 + 陈述句语序”,助动词 is 需放在主语 the nearest bank 后。
误:I don’t know what did he say at the meeting.(助动词 did 提前,语序错误
正:I don’t know what he said at the meeting.
【解析】从句主语是 he,谓语动词 said 需用过去式,遵循 “主语 + 谓语” 的陈述语序。
避坑技巧:语序判断三步法
1. 找到从句的连接词;
2. 识别从句的主语(连接词作主语时,连接词 = 主语);
3. 确保 “主语在前,谓语在后”,助动词 / 情态动词不提前。
易错点 3:that 的省略与不可省略混淆
错因分析
1. 过度省略:在需保留 that 的语境中误删,导致句子歧义或语法错误;
2. 多余添加:在可省略 that 的语境中冗余使用,显得累赘。
不可省略 that 的 5 种关键情况(必记)
1. 主语从句放句首时:That she refused the offer surprised all of us.(不可省略)拓展:用 it 作形式主语时,that 可省略:It surprised all of us (that) she refused the offer.
2. 宾语从句有多个并列分句时(第二个及以后 that 需保留):错误:He said he would come and he would bring a gift.(第二个 that 省略,易歧义)正确:He said that he would come and that he would bring a gift.
3. 表语从句中:The fact is that we have run out of time.(不可省略)
4. 同位语从句中:We heard the news that our team won the game.(不可省略)
5. 宾语从句前有插入语时:He said, to my surprise, that he had quit his job.(that 不可省略)
可省略 that 的 3 种情况
1. 宾语从句放及物动词后(常用动词:say/tell/think/believe 等):She told me (that) she would visit me next week.
2. 用 it 作形式宾语时:I find it necessary (that) we should practice more.
3. 宾语从句较短且逻辑清晰时:He thinks (that) English is easy to learn.
易错点 4:同位语从句与定语从句混淆
错因分析:两者均位于名词后,误将解释名词 “内容” 的同位语从句当作修饰名词的定语从句,连接词误用 which/that。
核心区分技巧
特征
同位语从句
定语从句
连接词
常用 that(不可省略),无 which
可用 that/which(作成分时可省略)
从句功能
解释名词的 “具体内容”(名词与从句等价)
修饰名词的 “特征 / 范围”(限定名词)
that 的作用
无词义,不作成分
有指代意义(指代先行词),作主语 / 宾语
典型例句对比
1. 同位语从句:We were excited at the news that our team won the championship.
【解析】从句 “our team won the championship” 是 news 的具体内容,that 无意义、不作成分,不可改为 which。
2. 定语从句:We were excited at the news that/which he told us yesterday.
【解析】从句 “he told us yesterday” 修饰 news(限定 “他昨天告诉我们的消息”),that/which 指代 news,作 told 的宾语,可省略。
拓展:常接同位语从句的抽象名词
fact(事实)、news(消息)、idea(想法)、promise(承诺)、doubt(怀疑)、suggestion(建议)、belief(信念)、truth(真相)等。
三、3 大避坑点技巧总结(精准突破易错点)
避坑点 1:“成分分析法” 快速选连接词(解决 80% 连接词错误)
步骤:
1. 确定从句类型(主 / 宾 / 表 / 同位语从句);
2. 分析从句内部是否缺少成分(主语 / 宾语 / 定语 / 状语);
3. 匹配连接词:
4. 缺主语 / 宾语 / 定语→连接代词(what/which/who 等);
5. 缺状语(时间 / 地点 / 原因 / 方式)→连接副词(when/where/why 等);
6. 无缺成分→从属连词(that/if/whether),表 “是否” 用 if/whether,否则用 that。
实例应用:
1. ______ he will go to Beijing depends on his parents’ decision.(主语从句,无缺成分,表 “是否”→Whether)
2. I don’t know ______ he needs.(宾语从句,缺宾语→what)
3. The problem is ______ we can get enough money.(表语从句,无缺成分,表 “是否”→whether)
避坑点 2:“语序铁律” 兜底(解决语序错误)
核心规则:所有名词性从句,无论主句是否为疑问语气,从句必须用 “连接词 + 主语 + 谓语” 的陈述语序;连接词(what/who/which 等)在从句中作主语时,看似 “疑问语序” 实则为陈述语序,无需调整。
【易错提醒】
误:Do you know when will the train arrive?(从句用疑问语序)
正:Do you know when the train will arrive?(连接词 when + 主语 the train + 谓语 will arrive)
正:Who will be our monitor hasn’t been decided yet.(who 作从句主语,语序正确)
【解析】从句主语是 he,谓语动词 said 需用过去式,遵循 “主语 + 谓语” 的陈述语序。
避坑点 3:“固定搭配 + 语境匹配” 双重验证(解决细节错误)
1. 固定搭配清单(必记):
The reason is that...(原因是……)
It is a pity/shame/necessary that...(形式主语从句,that 不可省略)
I doubt if/whether...(我怀疑是否……)
I’m sure/certain that...(我确定……)
depend on/insist on+whether(不可用 if)
2. 语境匹配原则:
表 “不确定 / 选择”→用 whether/if;
表 “具体内容 / 事实”→用 that;
表 “时间 / 地点 / 原因 / 方式”→用对应的连接副词。
