Ⅲ 高中英语名词性从句总结 谢谢
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。一、引导名词性从句的连接词分类 引导名词性从句的连接词可分为三类： 连词（5个）：that （宾语从句或表语从句中that有时可以省略） whether,if （均表示“是否”表明从句内容的不确定性） as if ,as though （均表示“好像”，“似乎”） 以上在从句中均不充当任何成分 连接代词（9个）：what, whatever, who, whoever, whom, whomever, whose, which, whichever 连接副词（7个）：when, where, how, why, whenever, wherever, however 不可省略的连词： 1. 介词后的连词 2. 引导主语从句和同位语从句的连词不可省略。 That she was chosen made us very happy. We heard the news that our team had won. 比较 whether与if 均为"是否"的意思。 但在下列情况下，只可用whether： 1. whether引导主语从句并在句首 2. 引导表语从句 3. whether从句作介词宾语 4. 常与 "or not" 连用；if 则不可。 5. 引导同位语从句 Whether he will come is not clear. 大部分连接词引导的主语从句都可以置于句末，用 it充当形式主语。 It is not important who will go. It is still unknown which team will win the match. 二. 主语从句 作句子主语的从句叫主语从句。主语从句通常由从属连词that，whether，if，as if和because等连接代词what，who，which，whatever，whoever，whom等以及连接副词how，when，where，why等词引导。that在句中无词义，只起连接作用；连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用，在从句中充当从句的成分。because引导表语从句。注：whom、who指人，what指物，whatever，whoever表示泛指意义。例如： What he wants to tell us is not clear. 他要跟我们说什么，还不清楚。 Who will win the match is still unknown. 谁能赢得这场比赛还不得而知。 It is known to us how he became a writer. 我们都知道他是如何成为一名作家的。 Where the English evening will be held has not yet been announced. 英语晚会将在哪里举行，还没有宣布。 有时为避免句子头重脚轻，常用形式主语it代替主语从句作形式主语放于句首，而把主语从句置于句末。主语从句后的谓语动词一般用单数形式。常用句型如下： （1） It + be + 名词 + that从句 （2）It + be + 形容词 + that从句 （3）It + be + 动词的过去分词 + that从句 （4）It + 不及物动词 + that 从句 另注意在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时，谓语动词要用虚拟语气“(should) +do”，常用的句型有： It is necessary (important, natural, strange, etc.) that … It is suggested (requested, proposed, desired, etc.) that… 三、宾语从句 名词从句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。 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, doubt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”。例如： I insist that she (should) do her work alone. 我坚持要她自己工作。 The commander ordered that troops (should) set off at once. 司令员命令部队马上出发。 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。例如： I want to know what he has told you. 我想知道他告诉了你什么。 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。此外，whether与if 在作“是否”的意思讲时在下列情况下一般只能用whether，不用if： a. 引导主语从句并在句首时；b. 引导表语从句时；c . 引导从句作介词宾语时；d. 从句后有“or not”时；e. 后接动词不定式时。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。 Everything depends on whether we have enough money. 一切要看我们是否有足够的钱。 I wonder whether he will come or not. 我想知道他来还是不来。 Can you tell me whether to go or to stay? 你能否告诉我是去还是留？ 4. 注意宾语从句中的时态呼应，当主句动词是现在时，从句根据自身的句子情况，而使用 不同时态。例如： I know (that) he studies English every day. （从句用一般现在时） I know (that) he studied English last term. （从句用一般过去时） I know (that) he will study English next year. （从句用一般将来时） I know (that) he has studied English since 1998. （从句用现在完成时） 当主句动词是过去时态（could, would除外），从句则要用相应的过去时态，如一般过去时，过去进行时，过去将来时等；当从句表示的是客观真理，科学原理，自然现象，则从句仍用现在时态。例如： The teacher told us that Tom had left us for America． 5. think, believe, imagine, suppose等等动词引起的否定性宾语从句中，要把上述主句中的动词变为否定式。即将从句中的否定形式移到主句中。例如： We don’t think you are here. 我们认为你不在这。 I don’t believe he will do so. 我相信他不会这样做。 四、表语从句 在复合句中，位于系动词之后作表语的从句叫表语从句。引导表语从句的关联词与引导主语从句的关联词大致一样，表语从句位于连系动词后，有时用as if引导。其基本结构为：主语 + 系动词 + that从句。例如： The fact is that we have lost the game. 事实是我们已经输了这场比赛。 That’s just what I want. 这正是我想要的。 This is where our problem lies. 这就是我们的问题所在。 That is why he didn’t come to the meeting. 那就是他为什么不到会的原因。 It looks as if it is going to rain. 看上去天要下雨了。 需要注意的，当主语是reason时，表语从句要用that引导而不是because。例如： The reason why he was late was that he missed the train by one minute this morning . 【注意】whether 可引导表语从句，但与之同义的if却通常不用于引导表语从句。 五、同位语从句 同位语从句说明其前面的名词的具体内容。同位语从句通常由that引导，可用于同位语从句的名词有advice、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、truth、wish、word等。例如： The news that we won the game is exciting. 我们赢得这场比赛的消息令人激动。 I have no idea when he will come back home. 我不知道他什么时候回来。 The thought came to him that Mary had probably fallen ill. 他想到可能玛丽生病了。 同位语从句和定语从句的区别： that作为关系代词，可以引导定语从句，充当句子成分，在从句中作宾语时可以省略； that引导同位语从句时，起连词的作用，没有实际意义，不充当句子成分，一般不能省略。 试比较下面两个例句: I had no idea that you were here．（that引导同位语从句，不能省略） Have you got the idea（that）this book gives you of life in ancient Greece？（that引导定语从句，作宾语，可以省略） 六、名词性that-从句 （1）由从属连词that引导的从句叫做名词性that-从句。That只起连接主句和从句的作用，在从句中不担任任何成分，本身也没有词义。名词性that-从句在句中能充当主 语、宾语、表语、同位语和形容词宾语，例如： 主语：That she is still alive is her luck. 她还活着全靠运气。 宾语：John said that he was leaving for London on Wednesday. 约翰说他星期三要到伦敦去。 表语：The fact is that he has not been seen recently. 事实是近来谁也没有见过他。 同位语：The fact that he has not been seen recently disturbs everyone in his office. 近来谁也没有见过他，这一事实令办公室所有的人不安。 形容词宾语：I am glad that you are satisfied with your job. 你对工作满意我感到很高兴。 2）That-从句作主语通常用it作先行词，而将that-从句置于句末，例如： It is quite clear that the whole project is doomed to failure. 很清楚，整个计划注定要失败。 It's a pity that you should have to leave. 你非走不可真是件憾事。 用it作形式主语的that-从句有以下四种不同的搭配关系： a. It + be +形容词+ that-从句 It is necessary that… 有必要…… It is important that… 重要的是…… It is obvious that… 很明显…… b. It + be + -ed 分词+ that-从句 It is believed that… 人们相信…… It is known to all that… 众所周知…… It has been decided that… 已决定…… c. It + be +名词+ that-从句 It is common knowledge that… ……是常识 It is a surprise that… 令人惊奇的是…… It is a fact that… 事实是…… d. It +不及物动词+ that-从句 It appears that… 似乎…… It happens that… 碰巧…… It occurred to me that… 我突然想起…… 七、名词性wh-从句 1）由wh-词引导的名词从句叫做名词性wh-从句。Wh-词包括who, whom,. whose, whoever, what, whatever, which, whichever等连接代词和where, when, how, why等连接副词。Wh-从句的语法功能除了和that-从句一样外，还可充当介词宾语、宾语补语和间接宾语等，例如： 主语： How the book will sell depends on its author. 书销售如何取决于作者本人。 直接宾语：In one's own home one can do what one likes. 在自己家里可以随心所欲。 间接宾语：The club will give whoever wins a prize. 俱乐部将给得胜者设奖。 表语： My question is who will take over president of the Foundation. 我的问题是谁将接任该基金会主席职位。 宾语补足语：She will name him whatever she wants to. 她高兴给他起什么名字就取什么名字。 同位语： I have no idea when he will return. 我不知道他什么时候回来。 形容词宾语：I'm not sure why she refused their invitation. 我尚不能肯定她为什么拒绝他们的邀请。 介词宾语： That depends on where we shall go. 那取决于我们去哪儿。 2）Wh-从句作主语也常用先行词it做形式主语，而将wh-从句置于句末，例如： It is not yet decided who will do that job. 还没决定谁做这项工作。 It remains unknown when they are going to get married. 他们何时结婚依然不明。 八、if, whether引导的名词从句 1）yes-no型疑问从句 从属连词if, whether引导的名词从句是由一般疑问句或选择疑问转化而来的，因此也分别被称为yes-no型疑问句从句和选择型疑问从句，其功能和wh-从句的功能相同， 例如： 主语：Whether the plan is feasible remains to be proved. 这一计划是否可行还有待证实。 宾语：Let us know whether / if you can finish the article before Friday. 请让我们知道你是否能在星期五以前把文章写完。 表语：The point is whether we should lend him the money. 问题在于我们是否应该借钱给他。 同位语：They are investigating the question whether the man is trustworthy. 他们调查他是否值得信赖。 形容词宾语： She's doubtful whether we shall be able to come. 她怀疑我们是否能够前来。 介词宾语： I worry about whether he can pass through the crisis of his illness. 我担心他是否能度过疾病的危险期。 2）选择性疑问从句 选择性疑问从句由关联词if/whether…or或whether…or not构成，例如： Please tell me whether / if they are Swedish or Danish. 请告诉我他们是瑞典人还是丹麦人。 I don't care whether you like the plan or not.我不在乎你是否喜欢该计划。 if和whether的区别： 1、 在动词不定式之前只能用whether 。如： 例8 I can’t decide whether to stay. 我不能决定是否留下。 2、 在whether …… or not 的固定搭配中。如： 例9 I want to know whether it’s good news or not . 我想知道是否是好消息。 3 、在介词后，只能用whether。如： 例10 His father is worried about whether he lose his work . 他的父亲担心是否会失去工作。 4、宾语从句放在句首表示强调时，只能用whether 。如： Whether this is true or not, I really don’t know. 这是否真的，我真的不知道。 （例11 Whether they can finish the work on time is still a problem . 他们是否能准时完成这项工作还是个问题。－－此例为主语从句，有误，感谢指出） 5、用if会引起歧义时，只用whether。如： 例12 Could you tell me if you know the answer ? 这句话有两种意思：“你能告诉我是否知道答案吗？”或“如果你知道答案，请告诉我，好吗？”。如用whether可避免歧义. 九、否定转移 1) 将think, believe, suppose, expect, fancy, imagine等动词后面宾语从句的否定词转移到主句中，即主句的谓语动词用否定式，而从句的谓语动词用肯定式。 I don't think I know you. 我想我并不认识你。 I don' t believe he will come. 我相信他不回来。 注意：若谓语动词为hope,宾语从句中的否定词不能转移。 I hope you weren't ill. 我想你没有生病吧。 2) 将seem, appear 等后的从句的否定转移到前面。 It doesn't seem that they know where to go. 看来他们不知道往哪去。 It doesn't appear that we'll have a sunny day tomorrow. 看来我们明天不会碰上好天气。 3) 有时将动名词，介词短语或整个从句的否定转变为对谓语动词的否定。 I don't remember having ever seen such a man. 我记得从未见过这样一个人。 (not否定动名词短语 having…) It's not a place where anyone would expect to see strange characters on the street. 在这里，人们不会想到在街上会碰上陌生的人。 (anyone 作主语，从句中的谓语动词不能用否定形式。) 4) 有时状语或状语从句中否定可以转移到谓语动词前。 The ant is not gathering this for itself alone. (否定状语) 蚂蚁不只是为自己采食。 He was not ready to believe something just because Aristotle said so. (否定because状语) 他并不因亚里斯多德说过如何如何，就轻信此事。 She had not been married many weeks when that man's younger brother saw her and was struck by her beauty. (否定状语many weeks) 她结婚还不到几个星期，这个人的弟弟就看见她了，并对她的美貌着了迷。
Ⅳ 高中英语名词性从句和定语从句的语法总结（详细一点）
名词性从句是由if, whether, that 和各种疑问词充当连接词所引导的从句，其功同名词一样。
一．主语从句
主语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。
1. It 作形式主语和it引导强调句的比较
It 作形式主语代替主语从句，主要是为了平衡句子结构，主语从句的连接词没有变化。而it引导的强调句则是对句子某一部分进行强调，无论强调的是什么成分，都可用连词that。被强调部分指人是也可用who/whom。
2. 用it 作形式主语的结构
(1) It is ＋名词＋从句
(2) it is ＋形容词＋从句
(3) it is ＋不及物动词＋从句
(4) it ＋过去分词＋从句
3. 主语从句不可位于句首的五种情况
(1) if 引导的主语从句不可居于复合句句首。
(2) It is said , (reported) …结构中的主语从句不可提前。
(3) It happens…, It occurs… 结构中的主语从句不可提前。
(4) It doesn’t matter how/whether …结构中的主语从句不可提前。
(5) 含主语从句的复合句是疑问句时，主语从句不可提前。
4. What 与that 在引导主语从句时的区别
What 引导主语从句时在句时在从句中充当句子成分，如主语．宾语．表语，而that 则不然。
定语从句也称为关系从句或形容词性从句，由关系代词（who, whom, whose, which, that）或关系副词（as, when, where, why）等引导。关系词除了起引导作用外，还在从句中指代前面的先行词，并在从句中担任一定的成分。
一、限定性定语从句和非限定性定语从句
定语从句就其与先行词的关系而言，可分为限定性定语从句和非限定性定语从句。限定性定语从句和先行词之间没有逗号，表示对先行词起修饰限制作用；而非限定性定语从句和先行词之间有逗号分开，是对先行词进行补充说明，相当于并列句。如：
He is the man who has strong personality. 他是个个性很强的人。（限定性定语从句）
My brother, who works abroad, is coming next week. 我哥哥在国外工作，他下周将回来。（非限定性定语从句）
注：1. 非限定性定语从句不能用that来引导，一般用which，as或who（指人）。用which或as引导时，既可以修饰主句的部分内容，也可修饰主句的全部内容。如：
He spoke confidently, which impressed me most. （which指代整个主句，在从句中作主语）
2. as引导的非限定性定语从句既可以放在主句之前，也可以放在主句之后，但which或who引导的非限定性定语从句不能放在主句之前。如：
As we all know, the moon is a satellite of the earth.
The large area is covered with thick snow, which affects people's life greatly.
3. 在限定性定语从句中，关系代词作宾语时可以省略；但在非限定性定语从句中，关系代词作宾语时不能省略。如：
The film (which) I saw last night is about a young teacher. (which可以省去)
She introced me to her husband, whom I hadn’t met before. (whom不能省去)
二、通常只用关系代词that，不用 which，who或whom的几种情况
1. 当先行词是all, everything, nothing, something, anything, little, much, none, few等时。如：
All that you want are here.
2. 当先行词被all, no, some, any, every, a few, a little, much, only, very等修饰时。如：
There is no person that doesn’t make mistakes.
3. 当先行词被序数词或形容词最高级修饰时。如：
This is the best film that I have ever seen.
4. 当出现两个或两个以上的先行词，并同时兼指人和物时。如：
We are talking about the people and countries that we have visited.
5. 当主句是以which 或 who 开头的特殊疑问句时。如：
Who is the person that is standing over there?
6. 当定语从句为there be 句型时，关系代词只能用that，但经常可以省略。如：
I know the difference (that) there is between you.
7. 当关系代词在从句中作表语时，常用that。如：
He does not seem to be the man that he was. 他似乎和过去不一样了。
三、as 与其他词连用引导的定语从句
as 引导定语从句时，可指人也可指物，通常与the same，such，so等连用，形式为：the same… as，such… as，as …as，so… as。As在定语从句中可作主语、宾语、表语等。如：
She knew he felt just the same as she did. 她知道他的感觉与她自己的一样。(as代替事，作宾语)
I lend you such books as will interest you. 我借给你使你感兴趣的书。(as代替物，作主语)
注：the same… as 和the same… that的用法不同。as引导的定语从句表示其内容与主句所讲的事物“相似”，指同类事物；that引导的定语从句表示其内容与主句所讲的事物是“同一个”，指同一事物。如：
This is the same pen as I lost yesterday. 这和我昨天丢的笔一样。（类似的笔）
This is the same pen that I lost yesterday. 这支笔就是我昨天丢的那支。（同一支笔）
四、“介词+关系代词”引导的定语从句
在“介词+which/whom”结构中，介词的选择取决于三种情况：
1．定语从句中谓语动词或表语的搭配。如：
This is the college in which I am studying.
He is the man about whom we are talking.
2．先行词与介词的习惯搭配。如：
The speed at which the machine operates is shown on the meter. 仪表上显示出这台机器运转的速度。
3．当定语从句为最高级时只能用of which; 否则用其他介词。如：
I have five dictionaries of which Longman Dictionary is the best.
I have five dictionaries among which Longman Dictionary is published in UK.
注：不可拆分的动词短语介词不能提前，如put up with；有的短语可能有不同的介词搭配，此时需要根据上下文来确定。如：be familiar with/to，compare with/to等。
有时为表意清楚，还可以在关系副词where/ when前加介词from, to等。如：
China is the birthplace of kites, from where kite flying spread to Japan, Korea, Thailand and India. 中国是风筝的故乡，从这里，放风筝的运动传到了日本、韩国、泰国和印度。
Ⅳ 高中英语：关于 名词性从句
记住那几个词比看语法有效的多，比如It is necessary (important, natural, strange, etc.) that … It is suggested (requested, proposed, desired, etc.) that…
同位语从句说明其版前面的名词的具权体内容。同位语从句通常由that引导，可用于同位语从句的名词有advice、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、truth、wish、word等。

Ⅵ 高考英语单选:名词性从句
lie in 是固定搭配，完整的句子是：Find out your interests lie in what.你的兴趣所在
因为不是定于从句，所以C错（没有先行词回）
选A没有in
那么选B 这是一答个地点状语where=in what

4. What 与that 在引导主语从句时的区别
What 引导主语从句时在句时在从句中充当句子成分，如主语．宾语．表语，而that 则不然。例如：
1) What you said yesterday is right.
2) That she is still alive is a consolation.
二．宾语从句
宾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。
1. 作动词的宾语
(1) 由that引导的宾语从句（that 通常可以省略）,例如：
I heard that be joined the army.
(2) 由what, whether (if) 引导的宾语从句，例如：
1) She did not know what had happened.
2) I wonder whether you can change this note for me.
(3) 动词＋间接宾语＋宾语从句。例如：

2. 作介词的宾语
例如：Our success depends upon how well we can cooperate with one another.
3. 作形容词的宾语
例如：I am afraid (that) I’ve made a mistake.
That 引导的从句常跟在下列形容词后作宾语：
Anxious, aware, certain, confident, convinced, determined, glad, proud, surprised, worried, sorry, thankful, ashamed, disappointed, annoyed, pleased, hurt, satisfied, content 等。也可以将此类词后的that 从句的看作原因状语从句。
4. It 可以作为形式宾语
It 不仅可以作为形式主语，还可以作为形式宾语而真正的宾语that 从句则放在句尾，特别是在带复合宾语的句子中。 例如：

6. 不可用that从句作直接宾语的动词
有些动词不可用于“动词＋间接宾语＋that从句“结构中，常见的有Envy, order, accuse, refuse, impress, forgive, blame, denounce, advise, congratulate等。例如：
He impressed the manager as an honest man. (right)
He impressed the manager that he was an honest man. (wrong)
7. 否定的转移
若主句谓语动词为Think, consider, wuppose, believe, expect, fancy, guess, imagine等，其后的宾语从句若含有否定意义，一般要把否定词转移到主句谓语上，从句谓语用肯定式。例如：
I don’t think this dress fits you well.（我认为这件衣服不适合你穿。）
三．表语从句
表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＋连系动词＋表语从句”。可以接表语从句的连系动词有be, look, remain, seem等。引导表语从句的that常可省略。另外，常用的还有the reason is that… 和It is because 等结构。例如：
1) The question is whether we can make good preparation in such a short time.
2) This is why we can’t get the support of the people
3) But the fact remains that we are behind the other classes.
4) The reason he is late for school is that he missed the early bus.
四．同位语从句
同位语从句就是在复合句中作名词的同位语的名词性从句。
1. 同位语从句的功能
同位语从句对于名词进一步解释，说明名词的具体内容，一般由that引导，例如：
1) The king’s decision that the prisoner would be set free surprised all the people.
2) The order that all the soldiers should stay still is given by the general.
2. 同位语在句子中的位置
同位语从句有时可以不紧跟在它所说明的名词后面，而是被别的词隔开。例如：
He got the news from Mary that the sports meeting was put off.
3. 同位语从句与定语从句的区别
(1) 定语从句中的that既代替先行词，同时以在从句中作某个成分（主语或宾语），而同位语从句中的that是连词，只起连接主句与从句的作用，不充当句中任何成分。
(2) 定语从句是形容词性的，其功能是修饰先行词，对先行词加以限定，描述定的性质或特征；同位语从句是名词性的，其功能是对名词进行补充说明。例如：
1) The news that he told me is that Tom would go abroad next year.（他告诉我的消息是汤姆明年将出国。）（第一个that引导的从句是定语从句，that在从句中作宾语）
2)The news that Tom would go abroad is told by him.（汤姆将出国的消息是他讲的。）（同位语从句，that在句中不作任何成分）

Ⅷ 高中英语语法 的名词性从句
名词性从句
名词性从句就是在句子中充当名词功能的以相关从属连词引导的从句，包括主语从句、宾语从句、表语从句和同位语从句四种。
1．主语从句：以连词 that what whom whose what which whoever whatever whichever where when how why 引导，在句子中充当主语。
例：What she said is not yet known.
How this happened is not clear to anyone.
Whoever comes is welcome.
That she will do well is her exam is certain.（It is certain that she will do well in her exam.）
注：it 为形式主语，
2．宾语从句：以连词 that who whom whose what 等引导，在句子中充当宾语。
例：He told us that he felt ill.
Everybody knows what happened.
I doubt whether he will succeed.
I wonder what he is writing about.
3．表语从句：以 that whether who whom whoever when where when 等引导，在句子中充当表语。
例：The trouble is that I lost his address.
The question is whether they will be able to help us.
That was what she did this morning.
This is why we puts off the sports meeting.
4．同位语从句：同位语从句有自己的先行词，它跟定语从句很相似，先行词包含从句中所含内容，从句不起修饰作用。我们将在学习定语从句时，在加以详细比较，多用在连词what 引导。（不用which，此外还可用whether who where 等也可以引导。在这章中我们着重学习that whether 引导的同位语从句，引导同位语从句的先行词常用的有：fact news idea whether reply promise truth report remark 等。
例：I heard the news that the Chinese football team defeated the Japanese team
last night.
I have no idea whether he will come or not.
They were all much worried over the fact that you were sick.
关于名词性从句的学习主要是我们应在学习中加以练习，在练习中反复学习，在多次重复学习和练习中加以掌握。
