that引导宾语从句时不可省略的九种情况
宾语从句中引导词的省略和替代技巧

宾语从句中引导词的省略和替代技巧在英语语法中,宾语从句是由一个引导词引导的从句,该从句作为动词的宾语。
然而,在实际的交流中,我们有时可以省略或替代宾语从句中的引导词,以简化语句结构或更加自然地表达意思。
本文将介绍宾语从句中引导词的省略和替代技巧。
一、省略引导词的情况1. “that” 的省略:在宾语从句中,如果引导词是“that”,且从句中的主语是句子的主语,则可以将“that”省略。
例如:- She said (that) she was tired.- He believes (that) they will win the game.2. “whether” 的省略:在宾语从句中,如果引导词是“whether”,且从句中的主语是动词的主语,则可以将“whether”省略。
例如:- He asked (whether) she had finished her homework.- I don't know (whether) they will come to the party.3. “if” 的省略:在宾语从句中,如果引导词是“if”,且从句中的主语是动词的主语,则可以将“if”省略。
例如:- He wonders (if) she is happy.- I doubt (if) it will rain tomorrow.二、替代引导词的情况1. “that” 的替代:在宾语从句中,除了直接省略“that”之外,还可以使用一些代替词来引导宾语从句,例如“whether”和“if”。
例如:- She wonders whether she should go to the party.- He asked if she had seen the movie.2. “what” 的替代:当宾语从句中的内容具体表示某事物或事实时,可以用“what”来替代整个从句。
例如:- I don't know what time it is.(我不知道现在是几点。

高中英语高考名词性从句专项复习(知识点+易错点+练习题)

2、宾语从句(1)常见的可以接that从句作宾语的动词有see, say, know, imagine, discover, believe, tell, show, think, consider, be sure, be afraid 等。
在可以接复合宾语的动词之后,如think, make, consider等,可以用it作形式宾语。
(2)That从句一般不能充当介词宾语,偶尔可作except, in的宾语。
3、表语从句(that不可省略)4、同位语从句连词that引导同位语从句时,应在某些抽象名词之后,如:fact, hope, desire, thought, suggestion, idea, news, problem, possibility 等,对前面的名词起补充说明的作用,that 在从句中不担当任何成分,不能省略。
二、whether/if 从句1>在表语从句和同位语从句中,只能用whether不能用if;当主语从句放于句首时,只能用whether不用if;当it作形式主语,主语从句放在句末时用whether或if均可;discuss后引导宾语从句时,必须用whether。
名词性从句中that和what的用法

名词性从句中that和what的用法作者:晏飞来源:《求学·新高考版》2021年第07期在高考英语中,名词性从句中that和what的用法是学生容易混淆的一个问题。
高考英语语法填空题中,连接词的用法是必考的内容,其中连接词that和what的辨析是高考命题人喜欢利用的考点。
理解这个语法点,能够让小知识发挥大作用,使学生在高考英语备考中事半功倍。
如何才能理解that和what的用法?观察下面这几个句子,让我们从中归纳出一个普遍的规律。
1.What he wants is a book. 我想要的是一本书。
2.That he wants to go there is obvious. 很明显他想去那里。
3.The result is that we won the game.结果是我们赢得了比赛。
4.This is what we want to know.這就是我们想知道的内容。
5.Is what he told us true?他告诉我们的是真的吗?6.We should pay attention to what the teacher is saying.我们应该关注老师正在讲解的内容。
7.I have no doubt that he will come. 我不怀疑他回来。
8.I have no idea what he did that afternoon.我不知道他下午做了什么事。
9.We live in what is called China.我们住在一个被称为中国的地方。
10.What you see is what you get.你所看到的就是你所得到的。
分析以上十个句子,我们不难发现一个规律:从句中缺少句子成分用what,从句中句子结构完整用that。
That只是起到单纯的连接主句和从句的作用,然而what除了连接主句和从句外,还在从句中充当句子成分。
一些英语基础知识薄弱的同学看到这里可能仍然是一头雾水。
【英语知识点】名词性从句引导词

【英语知识点】名词性从句引导词名词性从句的引导词有that、what、which、who、whoever、whom、whomever、if等。
名词性从句包括宾语从句、主语从句、表语从句和同位语从句四种。
一、that1、引导宾语从句时,that常可省略,但如果主句后跟有并列宾语从句时,只能省略第一个that;若宾语从句前插有别的从句时,that也不能省略。
例如:He told me(that)he was all right and that he would e to see me when he was free.他告诉我说他很好,并说在他有空时来看我。
2、that引导主语从句位于句首时不可省略.如果it作形式主语,而that从句置于句末,这时that可以省略。
例如:That he has lost his work is not true.他丢了工作不是真的。
=It is not true(that)he has lost his work.二、引导同位语从句时,切不可错用which。
例如:Word has e that some American guests will e to visit our school next week.有消息说下周将有一些美国客人来我校参观。
which表示特定事物中的"哪一个(些)",一般情况下在从句中充当定语,后接名词,在一定的语境中,它所修饰的名词可以省略,whichever是它的强语势"无论哪一个(些)"。
例如:I believe what (whatever) he says. 我相信他说的(不管他说什么我都相信)。
I will give her which (whichever) book she likes on the shelf. 这个书架上的(任何一本)书,只要她喜欢,我都会给她。
三、 what1. what除引导名词性从句外,还在从句中作成分,意为“所……的(东西)”,在含义上等于“名词+that”Yu Shan likes what she buys. 于杉所喜欢的是她买的东西。
