名词性从句练习题(含答案)经典
名词性从句练习题(含答案)经典一、名词性从句1．He took a trip to Beijing last week and ________ he saw at the Forbidden City impressed him deeply.A. thatB. howC. whatD. which【答案】 C【解析】【分析】句意：上周他到北京旅行了，他在故宫所看到的给他留下了深刻的印象。
分析句子结构可知，连词and后为一个名词性从句，因此应该使用what引导，且what在从句中作主语，故选C。
【点评】考查名词性从句，本题涉及what引导的主语从句。
2．Has it been announced ______?A. when are the planes to take offB. that are the planes to take offC. where are the planes to take offD. when the planes are to take off【答案】 D【解析】【分析】句意: 飞机什么时候起飞已经宣布了吗？此处是when引导的主语从句，且要用陈述句语序，故选D。
【点评】考查名词性从句，it作形式主语，关系副词when引导的从句作真正的主语。
3．In the past decade, our education system too much on grades. However, grades have a direct connection with future success is still a question.A. focused; whetherB. focused; ifC. has focused; whetherD. has focused; if【答案】 C【解析】【分析】考查时态和主语从句。
根据In the past decade,在最近的几十年里，可知句子用现在完成时态，our education system是句子的主语，单数形式，所以第一空填has focused；第二空是主语从句做主语，if是否，不能引导主语从句，所以第二空填whether。

完整版)高中英语名词性从句专项练习
完整版)高中英语名词性从句专项练习名词性从句是指在整个句子中充当名词的从句，包括主语从句、表语从句、宾语从句和同位语从句。
这四种从句的引导词可分为三类：连接词that、whether和if，连接代词what、who、whom、whose、which和whatever，以及连接副词when、where、how、why和whenever。
在选择连接词时，需要注意that和what的区别。
虽然它们都可以引导所有的名词从句，但what除了起连接作用外，还可以在从句中充当主语、宾语或表语。
而that只起连接作用，不充当任何成分。
另外，if和whether也需要正确使用，不能用if引导主语从句句首、表语从句或同位语从句，也不能与to do连用，以免引起歧义。
除了that和what以外的连接代词和副词，需要根据名词性从句的具体意义来选择适当的连接词。
这些连接词既具有疑问含义，又起连接作用，同时在从句中充当各种成分。
在宾语从句中，that可以省略，但在主语从句、表语从句、同位语从句和用it做形式宾语的宾语从句中，that不能省略。
同位语从句通常由名词加连接词和从句构成，连接词通常是that，但也可以根据含义选用whether、what、when、where等。
如果中心词是“意见、建议、命令”，从句要用虚拟语气（should）。
最后，需要注意同位语从句和定语从句的区别。
定语从句是先行词的修饰语，从句中that充当成分，做宾语时可省略。
而同位语从句表明中心词的具体内容，that在同位语从句中不做任何成分，只起连接作用，无具体含义，且不可省略。
在判断从句类型时，需要注意宾语从句的时态呼应。
will start the meeting.2.I don't know if/whether he will be able to come to the party.3.She asked if/whether I had XXX.4.I XXX it XXX.5.He asked if/whether I wanted to go to the movies with him.6.I'm not sure if/whether I should take this job offer.7.The teacher asked if/whether we had any XXX.8.He asked if/whether I had seen the new movie that justcame out.9.I'm not sure if/whether I can finish this project on time.10.She asked if/whether I had heard the news about the XXX。

名词性从句详解及练习
各类从句详解英语从句可以分为名词性从句、定语从句和状语从句三大类：下面我们逐一进行说明：一、名词性从句（主语从句、表语从句、宾语从句、同位语从句）主语从句、表语从句、宾语从句和同位语从句在复合句中的充当的成分和其名称相同，分别作主句的主语、表语、宾语和同位语。
上述这四种从句均被称为名词性从句。
所有的名词性从句均不能用逗号分开，并且它们都用相同的关联词，关联词如下：①主从连词：that (无意义), whether (是否), if (是否)（在句子中不充当任何成分）②连接代词：who (谁), whom (谁), whose (谁的), what (什么), which (哪一个)③连接副词：when (什么时候), where (什么地方), how (怎样), why (为什么)主从连词只起连接作用，连接代词和连接副词除了起连接作用外，还充当从句某一个成分。
另外，可以用whatever, whichever, whoever, who(m)ever等连接代词引导名词性从句，来加强语气。
下面分别对各种名词性从句进行介绍（一）主语从句（subject clause）在主句中用作主语的主谓结构称之为主语从句。
例如：That he will come to the discussion is certain.他来参加讨论是确定的。
That the moon moves round the earth is well known to all of us.月球绕地球转动，这是我们大家都熟知的。
When the meeting is to be held has not yet been decide.会议什么时候召开还没有决定。
主语从句放在句首，句子常常显得比较笨重，因此通常可以把it放在句首，作形式主语，而将主语从句放在后面。
例如上面的句子可以分别改写为：It is certain that he will come to the discussion.It is well known to all of us that the moon moves round the earth.It has not yet been decide when the meeting is to be held.下面再举一些例句：What they are after is profit.他们追求的是利润。

高中英语名词性从句详细讲解与练习（附答案）
高中英语名词性从句详细讲解与练习在句子中起名词作用的从句叫名词性从句。
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，因此根据它在句中不同的语法功能，名词性从句又可分为主语从句、宾语从句、表语从句、同位语从句。
引导名词性从句的词叫做连接词，包括：1.连词（在名词性从句中只起连接作用，不作成分）2.连接代词（在名词性从句中作主语、宾语或表语）3.连接副词（在名词性从句中作状语）所有的名词性从句的语序都是陈述语序。
I主语从句：是在主句中作主语的从句。
它由连接词引导，通常位于谓语动词之前。
连接词：1.连词：在从句中不充当任何成分，常见的引导主语从句的连词有that, whether oThat he got the first prize excited him much.他获得一等奖一事使他非常兴奋。
It is doubtful whether we can get there on time.我们能否按时到达那儿还不确定。
D that引导的主语从句:在从句中不作任何成分，也没有实际意义。
一般情况下that不可省略。
That light travels in straight lines is known to all.众所周知，光沿直线传播。
That you don't like him is none of my business.你不喜欢他不关我的事。
2）whether引导的土语从句:常置于句首，表示“是否”之意；if一般不引导主语从句。
Whether he can finish his task on time is of greatimportance.他是否能按时完成任务非常重要。
Whether you can succeed or not depends on howhard you work at it.你能否成功取决于你努力的程度。
2.连接代词：在从句中起名词或代词的作用，常作从句的主语、宾语、表语或定语,有具体意义且不能省略。

高考英语一一名词性从句高中英语名词性从句是高考考查的重点，包括主语从句、宾语从句、表语从句及同位语从句。
下面来进行—讲解。
名词性从句(1)主语从句1. 定义：用作主语的从句叫做主语从句。
2. 构成：关联词+简单句3•引导主语从句的关联词有三类:⑴从属连词that。
女口：That they were in truth sisters was clear from the facial resemblanee between them很明显，她们确是亲姐妹，她们的脸型很相似。
(2)从属连词whether。
如：Whether he ' II come here isn '他是否会来这里还不清楚。
(3)连接代词who, whom, whose, what, which, whoever, whatever, whichever 连接畐词where, when, how, why。
女口：What she did is not yet kn ow n.她干了什么尚不清楚。
How this happe ned is not clear to anyon e.这事怎样发生的，谁也不清楚。
Whoever comes is welcome.不论谁来都欢迎。
Wherever you are is my home ---- my only home. 你所在的任何地方就是我的家----我唯一的家。
解释：1.主语从句能用it作形式上的主语。
常以it作形式主语的句型有：A. It+be+形容词(obvious, true, natural, surprising, good, wonderful, funny, possible, likely, certain, probable, etc.)+that从句。
如：It is certain that she will do well in her exam. 毫无疑问她考试成绩会很好。
It is probable that he told her everyth ing很可能他把一切都告诉她了。
B. It+be+ 名词词组(no wonder, an honour, a good thing, a pity, no surprise, etc.)+that 从句。
如: It ' s a pityiat we can ' t g很遗憾我们不能去。
It ' s no surprise that our team should have won the game我们没赢这场比赛真意外。
C. It+be+过去分词(said, reported, thought, expected, decided, announced, arranged, etc.)+that 从句。
如：It is said that Mr. Green has arrived in Beijing.据说格林先生已经到了北京。
It isreported that Chi na has sent ano ther man-made earth satellite into orbit 据报道中国又成功地发射了一颗人造地球卫星。
D. It+seem, happen 等不及物动词及短语+that 从句。
如：It seems that Alice is not comi ng to the party at all. Alice 似乎不来参加晚会。
It happened that I was out that day.碰巧我那天外出了。
E. It+doesn ' t matt(makes no differenee, etc.)+连接代词或连接副词引起的主语从句。
如：It doesn' matter whether she will come or not.她是否来这无关紧要。
It makes no differenee where we shall have the meeti ng我们在哪里开会毫无区别。
F. 当that引导的主语从句出现在疑问句中时，要以it作形式主语，而把主语从句后置。
如：Is it true that the scie ntist will give us a lecture n ext week?下周那位科学家将给我们作报告是真的吗？ Does it matter much that they will not come tomorrow?他们明天不来很要紧吗？G. 当主语从句出现在感叹句中时，要以it作形式主语，而把主语从句后置。
如：Howstrange it is that the children are so quiet!孩子们这么安静真奇怪！ 2.注意连接代词whoever, whatever, whichever 等引导主语从句的含义Whoever comes will be welcome. (whoever=the person who)来的人将受到欢迎。
Whatever he did was right. (whatever=the thi ng that)他所做的事情是正确的。
Whichever of you comes in will receive a prize. (whichever=a nyone of you who)你们当中不论哪个进来将会得到奖名词性从句(2)宾语从句宾语从句是一种名词性从句，在句中作及物动词的宾语，或介词的宾语，或形容词的宾语。
根据引导宾语从句的不同连词，宾语从句可分为三类。
1. 由that引导的宾语从句。
That只有语法作用，没有实在的意义，在口语和非正式文体中可以省略。
例如：He said (that) he wan ted to stay at hom他说他想呆在家里。
She doesn ' t know (that) she is seriously她不知道她病得很严重。
I am sure (that) he will succeed我确信他会成功。
2. 由连接代词who, whom, whose, what, which 和连接畐U词when, where, why, how 引导的宾语从句。
这些连接代词和连接副词在宾语从句中充当某个成分。
例如：Do you kn ow who (whom) they are waiti ng for?你知道他们在等谁吗?He asked whose han dwrit ing was the besttfc 问谁的书法最好。
Can you tell me where the No.3 bus stop is你能告诉我3路公共汽车站在哪儿吗?I don ' t know why the train is la我不知道火车为什么晚了。
I can't imagi ne why he did that thing.我不能想像他为什么做了那件事。
Do you know why we have put off the sports meet till n ext mon th? 你知道我们为什么把运动会推迟到下个月吗？以上两个例句的宾语从句相当于一个特殊疑问句，分别为：why did he do that thing?和Whyhave you put off the sports meet till next mon th?由于宾语从句要求陈述句语序，故而在从句中它变成了陈述语序。
请看下列两组句子：How much does this coat cost?这件衣服值多少钱？I want to know how much this coat costs我想知道这件衣服值多少钱。
Where did you go yesterday?你昨天去哪儿了？Please tell me where you we nt yesterday 请告诉我你昨天去哪儿了。
当疑问代词what, who 在特殊疑问句中做主语时，该特殊疑问句本身就是陈述句语序，所以当该句用来做宾语时，语序不需要调整。
What's wrong with you?怎么了？He asked the girl what was wrong with he. 他问这个女孩怎么回事了。
What's the matter?怎么了？He asked the girl what was the matter 他问这个女孩怎么了。
What has happened to him?他发生什么事了？We want to know what has happe ned to him 我们想知道他发生了什么事。
同类句式还有：Who broke the window?谁打破的窗户？Who is in the classroom?谁在教室里？What made him so an gry 什么使得他如此生气。
3. 由if或whether引导的宾语从句。
表示是否”,二者通常可以互换。
例如：Lily asked if/whether she liked it.莉莉问她是否喜欢它。
I want to know if (whether) he lives there 我想知道他是否住在这儿。
He asked me whether (if) I could help him 他问我是否可以帮助他。
但语义有点区别：1) whethe强调犹豫和选择，多见于书面语中；if只限于条件，常用于口语。
例如: Write and tell me whether rm to come.请写信告诉我，我是否该来。
Write and tell me if rm to come.如果我该来，请写信告诉我（相当于说：若我不必来，那就不用费心写信给我了。
）2）whethe可引导各种名词性从名和让步状语从句，if只能引导宾语从句和条件状语从句。
由if引导的从句，首先要弄清楚是宾语从句，还是条件状语从句，然后再确定时态。
若是弓丨导条件状语从句，谓语动词应用一般现在（过去）时代替一般将来（过去将来）时。
___ 例如：If you don't go soon, you '如果你不.马上去就会迟到。
当if引导一个非真实条件句时，从句的谓语动词应用过去式（如果是be,则不论主语的人称和数，一律用were）,主句谓语动词用“would动词原形”例如：If every one in the country knew first aid, many lives would be saved 如果每个国民都懂得急救（的知识），许多生命就会得以挽救。
