名词性从句的使用可以使句子更加丰富，表达更加准确。
本文将介绍名词性从句的种类及其作用。
一、主语从句主语从句是名词性从句的一种常见形式，它在句子中充当主语的角色，起到句子的主题和核心的作用。
主语从句通常以“that”或“whether”引导。

它常见于及物动词后，也可用于介词后。

名词性从句在复合句中起名词作用的从句叫做名词性从句。
名词性从句的作用相当于名词，因此主语从句、表语从句、宾语从句和同位语从句分别作主句的主语、表语、宾语和同位语。
主语从句：Who will win the match is still unknown.宾语从句：I want to know what he has told you.表语从句：The fact is that we have lost the game.同位语从句：The news that we won the game is exciting.引导名词性从句的连接词可分为三类：连接词(不充当从句的任何成分)：that ,whether ,if连接代词：what, who, whom, whose, which, wh+ever连接副词：when ,where ,how ,whyObject Clauses 宾语从句一、宾语从句的概念：宾语从句在复合句中作主句的宾语。
位置：通常放在主句谓语动词（及物动词）或介词之后。
句子结构：主句+连词(引导词)+ 宾语从句e.g. She asked if these answers were right.We can learn what we do not know.He will talk to us about what he saw in the U.S.A.I don’t know where we will hold the meeting.通过观察，我们可以知道宾语从句的语序用陈述语序：连接词+主语+谓语+其他成分1)Could you tell me______.A. you will get here whenB. when will you get hereC. get here when you willD. when you will get here2) Mother asked his son what ______for lunch at school.A. did he hadB. does he hadC. he hasD. he had3) Pointing to the young plant, he asked me ____ that was the one we had seen in the picture.A. whatB. ifC. whereD. how二、连接词1、从属连接词(不充当从句的任何成分)：that ,whether ,if1）、I hear (that) he will be back in an hour.2）、I want to know if /whether he will go to the park with us用it做形式宾语的宾语从句时，it常可以放在动词think, find, consider, believe, feel, make 等后作为形式宾语，而真正的宾语——that从句则放在句尾）（此时that一定不可以省略）I think it necessary that you should read English aloud.We heard it that she would get married next month.3、that从句位于句首时，that不可省略。

2．as if/as though引导的表语从句 as if/as though引导的表语从句常跟在be动词seem，look，taste， sound，feel，appear等动词之后。
The thick smog covered the whole city. It was as if a great black blanket
3．连接代词、连接副词引导宾语从句时不能省略，并在从句中充当 句子成分。
We promise whoever attends the party will have a chance to have a photo taken with the movie star.
我们保证，任何参加这个聚会的人都有机会与那个电影明星合影。
between them. 从她们的面貌相似度就能清楚地看出是亲姐妹。 ③What struck me mo's deep love for his
son. 影片中最打动我的是父亲对儿子深厚的爱。
易混辨析 whether与if引导主语从句的区别： 主语从句位于主句谓语动词前，表示“是否”，只能用whether而不 能用if引导；若用it作形式主语，则if与whether可互换。
答案与解析：what 句意为：这就是父亲教给我的——永远面对困难并寄予最 大的希望。本题考查表语从句。根据句意可知，表语从句中taught me后缺少直接 宾语——“教会了我什么”，因此用what引导。
高中英语2024届高考名词性从句知识分类讲解(主语从句+宾语从句+表语从句+同位语从句)
高考英语名词性从句知识讲解名词性从句是指在复合句中起名词作用的句子，功能相当于名词词组。

名词性从句讲解归纳及例题2011-06-29 09:14:00| 分类：Grammar 语法| 标签：|字号大中小订阅在主从复合句中，从句可以充当主句的主语、表语、宾语或同位语。
由于在多数情况下，主语、表语、宾语或同位语这四种句子成分由名词性词类充当，所以，我们把这些作用相当于名词的从句统称为名词性从句，把充当主语、表语、宾语或同位语的从句分别称为主语从句、表语从句、宾语从句或同位语从句。
也就是说充当什么成分就叫什么从句。
名词性从句由连接词（或关联词）引导。
常用的连接词有：连接词作用whether 是否that (本身无词义)只起连接词作用，引导从句，在从句中不作任何成分who, whom, whose which 哪一个what 什么，所…的在从句中分别作主语、宾语和定语在从句中分别作主语、宾语和定语在从句中分别作主语、宾语和定语cwhen什么时候，where什么地方how怎样、怎么，why为什么除了起连接词作用外，还在从句中作状语疑问词（who, whom, whose, what, which, where, why, when, how）可以引导主语、宾语和表语从句。
它们的特点是：1、疑问词有本身的词义；2、疑问词在从句中担当句子成分，如主语、宾语或状语；3、这种疑问词引导的从句一律用陈述语序，不能用疑问语序。
For example:Do you know whom they are looking for? 你知道他们在找谁吗？（宾语从句，陈述语序。
不能是whom are they looking for?）I don’t know who did it.我不知道这是谁干的。
（宾语从句。
在从句中如果疑问词作主语，其陈述语序和疑问语序一致。
）She asked me where I had been.她问我到哪儿去了。
（宾语从句。
陈述语序，不能是where had I been. 直接引语，间接引语。

第二讲：名词性从句（二）宾语从句、表语从句和同位语从句一、宾语从句1.什么是宾语从句？在句子中用作宾语的从句叫宾语从句。
引导宾语从句的关联词与引导主语从句表语从句的关联词大致一样，在句中可以作谓语动词或介词及非谓语动词的宾语。
2.宾语从句都有哪些类型？（1）. 由连接词that引导的宾语从句由连接词that引导宾语从句时，that在句中不担任任何成分，在口语或非正式的文体中常被省去，但如从句是并列句时,第二个分句前的that不可省。
例如：He has told me that he will go to Shanghai tomorrow.他已经告诉我他明天要去上海。
We must never think (that) we are good in everything while others are good in nothing. 我们决不能认为自己什么都好，别人什么都不好。
注意：在demand、order、suggest、decide、insist, desire, request, command等表示要求、命令、建议、决定等意义的动词后，宾语从句常用“（should）+ 动词原形”。

（2）. 用who，whom, which, whose, what, when, where, why, how, whoever, whatever, whichever等关联词引导的宾语从句相当于特殊疑问句，应注意句子语序要用陈述语序。

She always thinks of how she can work well.她总是在想怎样能把工作做好。
She will give whoever needs help a warm support.凡需要帮助的人，她都会给予热情的支持。
（3）. 用whether或if引导的宾语从句，其主语和谓语的顺序也不能颠倒，仍保持陈述句语序。
例如：Whether there is life on the moon is an interesting question.月球上有没有生命是个有趣的问题。
The question is whether she should have a low opinion of the test?现在的问题是她是否应该有一个低意见的测试？Everything depends on whether we have enough money.一切要看我们是否有足够的钱。

例如：The teacher told us that Tom had left us for America．1.主句用一般现在时，从句可用任意时态。
2.主句用过去时，从句用过去某个时态。
