英语微课堂—带你闯关“名词性从句”

很多人觉得英语学习有难度,其实做好两个方面就可以,一是单词量够,二是语法知识全面,加之做适当的练习,分数就不会低。今天,橙子妈妈给大家整理的这篇文章便是英语语法方面的知识——名词性从句,考点、考法、解题步骤、典型例题都有!


名词性从句知识点回顾

在进入主题之前,让我们先回顾一下以下几个经典句子。有没有觉得很熟悉?这是高中阶段必修三的课内原句。其实,当我们在看一些科学纪录片的时候经常会看到这样的句式,大家有没有觉得它们有时候让人晦涩难懂?没有关系,跟着橙子妈妈一起梳理今天这个知识点之后,你会发现原来它们也是华丽外表下的“小羊羔”,特别容易理解。

1. No oneknows exactly how the earth began, as it happened so long ago.

没有人确切知道地球是怎样开始形成的,因为在很早很早以前地球就形成

2.However, according to a widely accepted theory, the universe began with a"Big Bang" that threw matter in all directions.

然而,一种普遍为人们所接受的理论是:宇宙起源于一次大爆炸,这次大爆炸将物质投射到四面八方。

3. What many scientists believe is thatthe continued presence of water allowed the earth to dissolve harmful gases andacids into the oceans and seas.

很多科学家相信,由于地球上长期有水存在,使得地球得以把有害气体和酸性物质溶解在海洋里。

4. It was not immediately obvious that water was to be fundamental to the development of life.

水对于生命的发展会起关键作用,这一点在当时并不明显。

在定语从句的课上,橙子妈妈说过,看到一个句子,首先第一步就是要学会分析句子结构,进行断句。来,跟着橙子妈妈在心里默念三遍“分析结构,学会断句”,

以第一个句子为例进行结构划分:

通过这个模式我们很快可以得知这个句子中包含了1个主句(时态①所在句子),2个从句(连接词①+时态②;连接词②+时态①)的主从复合句,怎么样?是不是特别容易分析出来?掌握了这个办法无论你的基础如何,看懂句子都将不是一件难事!

此时的你应该迫不及待想要去证实自己的能力了吧?具体在解题中怎么去运用呢?别着急,橙子妈妈满足你的小骄傲!

例如:

按照橙子妈妈以上介绍的判断复合句的方法(句子+连接词+句子)中间是不是刚好缺少的是:连词

答案是不是快速得出!

那么,为了能够更加清楚地确定自己所填的是什么从句,我们将进一步阐述从句三兄弟之“二师兄”—名词性从句

名词性从句如何考察

第一步:确立身份,熟知“二师兄”定义


名词性从句是在句子中起名词作用的句子。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。

例如:

根据这个概念我们得出二师兄(名词性从句)原来是由好几个小分支组成的,怪不得肚子容量那么大!让我们很多人望而却步!

第二步:理清小分支,一个萝卜一个坑

从句是在复合句中充当主语的从句,通常放在主句谓语动词_之前或由形式主语it代替,而本身放在句子末尾(通常我们称之为it作形式主语)

从句就是在复合句中作宾语的名词性从句,通常放在主句谓语动词(及物动词) 或介词之后。或由_it_代替,而本身放在句子末尾(通常我们称之为it作形式宾语)

从句在复合句中作表语的名词性从句,放在_系动词_____之后,一般结构是“主语+系+表”。可以接表语从句的常见连系动词

be (am,is,are) ;seem, appear, prove, turn out, grow ;sound, smell, feel, taste, become等。

从句就是在复合句中作__抽象名词__的同位语的名词性从句。引导的同位语从句前面的名词常见的有: idea, fact, news, belief, thought, doubt,suggestion; proof, message, order, conclusion, desire, theory, truth, word 等.

比起大师兄-定语从句,二师兄的知识量比较大,所以花费的精力和时间都需要更多一些,才能理解的更加透彻。

现在各位小伙伴们能不能区别出来我们开篇提到的几个句子了呢?

第三步:找准关连词,警惕高危区

名词性从句常用的引导词 引导名词性从句的连接词可分为三类:

英语微课堂—带你闯关“名词性从句”2. 连接代词(9个):

what, whatever, who,whoever, whom, whomever, whose,which, whichever 在句中作主语、宾语、表语成分

3. 连接副词(7个):when, where, how, why,whenever, wherever, however在句中作状语成分

第四步:打通周身脉络,关注相关知识点



I.主谓一致(单个从句做主语,谓语动词用单数两个或以上从句并列做主语,谓语动词用复数)

When the meetingwill begin has not been decided yet.何时开会还没有决定。

2.When they willhole the meeting and where they will hold the meeting have not been decided yet .

II.it作形式主语和形式宾语

1. I think_______worthwhile that we spent so much money on these books.(it)

2. _______ is hardto decide when and where we will hold our sports meeting. (it)

III. 时态问题(宾语从句)

初中学习过的知识点,橙子妈妈教你一句口诀:

主过从过(主句过去时从句相应过去相关的时态),主现从任意(主句现在时从句根据句子需求定),客观真理一般时(客观真理无论何时都用一般时)

例如:

She askedme whether I had returned thebooks to the library.主过从过

No one knowsexactly how the earth began.主现从任意

My teacher oncetold us that light travels faster than sound.客观真理一般时

IV. 名词性从句的虚拟问题(贯穿高一高二重点句式)

She insisted that she (should)

organize the trip properly.(必修一unit3)

John Snow suggested that the source of all thewater supplies be examined.(必修五unit1)

结论:表示建议、要求、命令,坚持等动词suggest、advise、propose、demand、require、insist .request、command、order后的从句谓语动词用(should)+V-原形

V. whoever/whatever/whichever/whomever引导的名词性从句(泛指意义,翻译为“无论)

IV. 同位语从句与定语从句的区别

(1) Thenews that Mr. Wang will be our new English teacher is true. (同位语从句)

(2)Thenews that he told me yesterday is true. (定语从句)

同位语从句前的名词是一个具有抽象意味的名词。从句就是其内容。that在从句中不充当成分。

定语从句就是对前先行词进行修饰限定,关系词应代替先行词在从句中充当句子成分。

名词性从句解题三步骤

天下从句都一家,所以他们之间既有不同点也有相似之处。对于从句分析方式都是按照橙子妈妈所说的“分析结构,学会断句;抓住连接词,确定从句种类”

在解题中,我们只要跟着下面的步骤,就没有你解决不了的难题:

1.首先确定空格处所在从句是否为大师兄定从还是二师兄名词性从句或者其他句子。然后分析从句在整个句中所充当的成分,确定从句所属类型:主语从句、宾语从句、表语从句还是同位语从句。

2.判断从句中的连接词

(1)若从句不缺少成分则要考虑句意是否完整,若句意不完整,则需用whether/if;若句意完整,则用that。

(2)若从句缺少主、宾或表语,则用连接代词

(3)若从句缺少状语,则用连接副词

3.注意都用陈述语序;另外,还需注意一些特殊的引导词(如whether,because,as if 等)的用法。
