分析句子可知，主语从句中的lie为不及物动词，所以主句中缺少状语，因此填where。
expect sth.to do.固定短语，“期望某事发生”，sth. be expected to do.意为”某事有可能发生“。
make sth. clear to sb为固定搭配，意为“向某人阐明某事，使某人弄清某事”。
本句中make的宾语是where his failure lies 是被弄清楚，要用动词不定式的被动形式。
因此选C。

(完整word)各类从句讲解
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。
(完整word版)高中英语名词性从句讲解
适用文档名词性从句解说在复合句中起名作用的从句叫做名性从句。
它包含主从句、从句、表从句和同位从句。
名性从句是中学段的一个重要法目，在年的高考取几乎都波及到，而且每年的命各有化。
解析届高考名性从句考的焦点主要有以下六个方面1. 考名性从句的序2. 考引 that 与 what 的区3. 考 it 在名性从句中作形式主或形式的用法4. 考 whether 与 if 的区5. 考名性从句中的疑+ever 引的名性从句与no matter+ 疑引的状从句的区6.考名性从句的虚气法重点解析一、名性从句主从句、表从句、从句、同位从句，在整个句子中所起的作用，相当于一个名。
所以，四种从句通称名性从句。
引名性从句的接可分三：接： that, whether, if（不充任从句的任何成分）接代： what, whatever, who, whoever, whom, whose, which.接副： when, where, how, why1.主从句作句子主的从句叫主从句。
主从句往常由附属that ，whether ，if和接代what ，who，which ，whatever ， whoever 以及接副 how， when， where， why 等引。
that 在句中无，只起接作用；接代和接副在句中既保存自己的疑含、又起接作用，在从句中充任从句的成分。
比如：What he wants to tell us is not clear.他要跟我什么，不清楚。
It is known to us how he became a writer.我都知道他是如何成一名作家的。
Where the English evening will be held has not yet been announced.英晚会将在哪里行，没有宣告。
有防止句子重脚，常用形式主it取代主从句作形式主放于句首，而把主从句置于句末。
主从句后的一般用数形式。
完整版)名词性从句用法归纳
完整版)名词性从句用法归纳名词性从句是指在句子中作名词角色的句子，可以充当主语、宾语、表语、同位语、介词宾语等。
名词性从句包括主语从句、宾语从句、表语从句和同位语从句。
引导名词性从句的连接词可以分为三类。
第一类是从属连词，包括that、whether和if。
在宾语从句或表语从句中，that 有时可以省略。
第二类是连接代词，包括what、who、which 等。
这些代词在从句中做成分，不可以省略。
第三类是连接副词，如when、where、how等，也不可以省略。
在一些情况下，that可以省略，如定语从句中做宾语、引导宾语从句或表语从句时。
但在定语从句中做主语、由that引导同位语从句时，以及宾语从句中真正的that不可以省略的情况下，that不能省略。
主语从句是指作句子主语的从句。
主语从句通常由从属连词that、whether等，连接代词what、who、which等，以及连接副词how、when、where等引导。
2、连接词的使用：连接词在句子中起到连接的作用，其中that在句子中没有实际的意义，只是起到连接从句和主句的作用。
而连接代词和连接副词则在句子中既保留了自己的疑问含义，又起到连接从句和主句的作用，同时在从句中充当从句的成分。
例如，whom和who指人，what指物，而XXX和whoever则表示泛指意义。
举个例子，What he wants to tell us is not clear.表示他想告诉我们什么并不清楚。
另外，为了避免句子头重脚轻的情况，有时我们会用形式主语it代替主语从句，并将主语从句放在句末。
这种情况下，主语从句后的谓语动词一般使用单数形式。
常用的句型有：（1）It + be +名词+ that从句，如It is a fact that（事实是）；（2）It + be +动词的过去分词+ that从句，如It is said that（据说）；（3）It +不及物动词（vi）+ that从句，如It seems that （似乎）；（4）It + be +形容词+ that从句，如It is naturalthat（很自然）。
复习名词性从句Microsoft Word 文档
复习名词性从句首先，我们要弄清楚名词性从句的概念：具有名词的性质的从句。
那么名词在句子中具有哪些句法功能呢?一般说来,名词可作主语，宾语，表语和同位语。
因此名词性从句就包括主语从句，宾语从句，表语从句和同位语从句。
为了便于理解和掌握，我们放在一起来讲解。
高考考点：1.名词性从句中连接词的运用：名词性从句中的连接词有：连接连词that / whether / as if,连接代词what / who/ which / whose / whatever / whoever / whomever / whichever,连接副词where / when / why / how / wherever / whenever。
（1）that的用法：①主语从句,表语从句,同位语从句中用that但不能省略：That they are good at English is known to us all.The problem is that we don’t have enough money.She expressed the hope that they would come to China one day.②宾语从句中的连接词that有时可省有时又不可省,在以下几种情况中that不能省略：I.当that从句和主句谓语动词间有插入词语或者从句主语间有插入语时,that不可省略;II.当that 从句与另一名词性从句并列作宾语时,that不能省;III.当that作介词宾语时,that不可省掉：He judged that because he was a child, he did not understand wineEveryone knew what happened and that she was worried.The reason lies in that she works harder than the others do.③that从句作主语和宾语时,可以用it 来替换成以下几种结构表达。
(完整版)名词性从句归纳
名词性从句归纳一、名词性从句概说、结构与功能名词性从句是起名词作用的从句，其功能相当于名词词组，在复合句中可作主语、宾语、表语和同位语。
与之对应的名词性从句分别为主语从句、宾语从句、表语从句和同位语从句。
二、主语从句1、主语从句的类别●以从属连词that 引导的主语从句。
（从句位于句首，that通常不省略）→ That she will come to the conference has excited every one of us.●以从属连词whether 引导的主语从句。
（从句置于句首时一般不用if来代替whether）→ Whether we’ll go outing depends on the weath er.●以连接代词（what, whatever, who, whoever, which, whichever等词）引导的主语从句。
→ Whoever will be in charge of the project hasn’t been decided yet.【注】what 与that在引导主语从句时，what 不但起连接作用，而且还有具体意义，意为“所…的”，相当于the things that结构；而that则无词义。
即如果从句中不缺少主语或宾语时，选择that，否则用what。
●以连接副词（when，where, how, why 等词）引导的主语从句.→ When the new road is open to traffic has not been made clear.2、用it 作形式主语的主语从句注：以下几种特殊情况必须用it作形式主语：⑴ It is + adj. + that 从句常见的形容词有：necessary，right，likely，wrong，important，certain，clear，obvious，strange 等。
→ It is likely that there will be a snowstorm tomorrow.⑵ It is + noun + that 从句常接这种句型的名词有：a pity, a shame, good news, a fact, an honor, a wonder, no wonder 等。
名词性从句整理
名词性从句一、定义：名词性从句在功能上相当于名词，是一个句子分别充当另一个句子的主语、表语、宾语和同位语，由此被称为主语从句，表语从句，宾语从句和同位语从句。
辨别下列从句属于哪种名词性从句并分析：1）Why they haven’t left yet is unclear.2）It was good news that everyone got back safely.3）Polly didn’t know which way she should go.4）I’m interested in who that tall man is.5）We all thought it good news that the fog had finally gone.6）My question is whether Polly can find her way home.7）The fact that Polly didn’t ask for the man’s name is a pity.总结：名词性从句主要由陈述句、一般疑问句、特殊疑问句充当。
1）陈述句充当名词性从句时，由that引导；2）一般疑问句充当名词性从句时，由if或whether引导从句；3）特殊疑问句充当名词性从句时，由疑问词本身做连词引导从句。
4）名词性从句的语序应使用陈述句语序，不可用一般问句语序。
二、引导名词性从句的从属连词及从句语序1.连接词that;功能1）不充当句子成分2）无词义3）只起连接作用。
2.if/whether;功能:1）意为“是否”，有词义2）不做句子成分3）起连接作用翻译:1)I know that he will come this evening. ____________ 2) Whether we will go there or not hasn’t been decided yet._____________________________3.连接代词：what(ever), which(ever), who(ever), whom(ever), whose(ver)功能：1)有词义2)引起从句3)且在从句中充当一定的句子成分，常做从句中的主语、宾语、表语和定语。
(完整版)高中英语名词性从句详解
(完整版)高中英语名词性从句详解名词性从句【名词性从句】相当于名词，可分别作主句的主语、表语、宾语和同位语。
因此，名词性从句分为主语从句、表语从句、宾语从句和同位从句。
宾语从句——在复合句中作主句及物动词的宾语，也可作介词或某些形容词的宾语1。
连接词从属连词that whether if 不担任成分只起连接作用关系代词who whom whose whatwhich既担任成分，又起连接作用。
主语,宾语或表语等关系副词when where why how 既担任成分，又起连接作用常担任状语◆I think (that） you will like the pictures。
◆ He has become what he wanted to be ten years ago。
◆ I don't know why Jane was late for school this morning。
◆The teacher is pleased with what she said。
◆I’m afraid that I can’t go to the party。
2.注意事项(that通常可以省略）。
但如从句是并列句时，第二个分句前的that 不可省。
◆He told me (that） he was ill and that he would not come to the party。
②陈述语序◆ I want to know what he has told you。
◆ She will give whoever needs help a warm support。
③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。
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。
名词性从句讲义 完整版!
名词性从句一，名词性从句的概念：1, 相当于名词，分为主语从句、表语从句、宾语从句和同位语从句2，名词性从句的引导词：that, whether, if (一般是宾语从句)，as if(表语从句)，who, whom, whose, what, which, when, where, why, how,以及由how组成的词组，如：how many, how long, how far两组需要注意的连接词that/what1）that和what都可以引导名词性从句，但that是连接词，本身无词义，仅起连接作用，不在从句中担任任何成份；what是连接代词，不仅引导名词性从句，而且在从句中充当一定的成份，如主语、宾语或表语。
e.g: That he stole a bike was true.The important thing is what you do, but not what you say.高考真题：_______ we can't get seems better than _______ we have.A. What; whatB. What; thatC. That; thatD. That; what2）whether和if均可引导动词后的宾语从句，常可互换。
a.在介词后面只能用whether，不能用if。
例如：①This depends upon whether we are determined to do it.b.在动词不定式之前，只能用whether，不能用if。
例如：①He doesn't know whether to stay or not.c.引导主语从句，表语从句，同位语从句时只能用whether。
例如：①It is unknown whether he will come. 他是否来还不知道。
②The question is whether they can take our advice.3.The question whether he'll come is unknown.3）doubt用于肯定结构时，后面用whether/ if引导名词性从句；用于否定结构或疑问结构时，后面用that引导名词性从句。

(完整word版)高中英语语法总结-名词性从句
名词性从句在句子中起名词作用的句子叫名词性从句(Noun Clauses ）。
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。
根据从句在句子中的功能分根据从句的性质分 定语从句形容词性从句 主语从句名词性从句 宾语从句表语从句同位语从句状语从句副词性从句第一节 知识点讲解一．【主语从句】顾名思义，主语从句在句子中作主语。
有时本身出现在主语的位置上，也有时出于句子结构的考虑退到句子的尾部，前面用形式主语it 代替。
从句作主语时，谓语动词一般为单数形式。
如:What I saw was beyond any verbal description.That his hair was turning grey worried him a bit.Why the company denied the contract is still unknown.When and where the government will build a city square is under discussion.It is pretty annoying that a small part of the machine is missing.It remains to be seen whether the new novel will be well received.Tips: 主语从句的that 绝对不能省去。
因为句子是不能做主语的，故用that 引导。
若去掉则没有了主语，而宾语从句的that 可省。
主语从句：That he is right is known to all of us.宾语从句：We all know (that) he is right.1. It 作形式主语和it 引导强调句的比较为了防止句子头重脚轻，通常把形式主语it 放在主语位置，真正主语搁置于句末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。

本句时一个主语从句，it作形式主语，真正的主语为that what plays a vital role in driving away one's anxiety is one's sweet childhood memories.，主语从句中又有一个主语从句，且此主语从句中缺少主语，所以用what引导。

名词性从句知识点总结(word文档物超所值)
名词性从句名词性从句相当于名词，可分别作主句的主语、表语、宾语和同位语。
因此，名词性从句厅分为主语从句、表语从句、宾语从句和同位从句。
（一）引导名词性从句的连接词1、连接代词：who, whose, whom, what, which。
有词义，在从句中担任成分，如主语、表语、宾语、或定语等。
2、连接副词：when, where, why, how。
有词义，在从句中担任成分，作状语。
3、连接词：that, whether, if, as if。
that 无词义，在从句中不担任成分，有时可省略；if (whether), as if虽有词义，但在从句中不担任成分。
注意：1、连接代词与连接副词在句中不再是疑问句，因而从句中谓语不用疑问式。
连接代词与连接副词在从句充当句子成分，连接词whether 和if（是否），as if（好象）在从句中不充当句子成分，只起连接作用。
根据句义，如果连接代词与连接副词，whether、if 和as if都用不上时，才用that作连接词（that本身无任何含义）。
2、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.（二）主语从句1、主语从句在复合句作主语。
e.g. Who will go is not important.2、用it作形式主语，主语从句放在句末。
e.g. It doesn’t matter so much whether you will come or not.主要句型有：（1）It+be+形容词+that从句。
It is probable that he told her everything. 很可能他把一切都告诉她了。
（2）It+be+名词词组(no wonder, an honour, a good thing, a pity, no surprise, etc.)+that从句。

名词性从句归纳一、名词性从句概说、结构与功能名词性从句是起名词作用的从句，其功能相当于名词词组，在复合句中可作主语、宾语、表语和同位语。
与之对应的名词性从句分别为主语从句、宾语从句、表语从句和同位语从句。
二、主语从句1、主语从句的类别●以从属连词that 引导的主语从句。
（从句位于句首，that通常不省略）→ That she will come to the conference has excited every one of us.●以从属连词whether 引导的主语从句。
（从句置于句首时一般不用if来代替whether）→ Whether we’ll go outing depends on the weath er.●以连接代词（what, whatever, who, whoever, which, whichever等词）引导的主语从句。
→ Whoever will be in charge of the project hasn’t been decided yet.【注】what 与that在引导主语从句时，what 不但起连接作用，而且还有具体意义，意为“所…的”，相当于the things that结构；而that则无词义。
即如果从句中不缺少主语或宾语时，选择that，否则用what。
●以连接副词（when，where, how, why 等词）引导的主语从句.→ When the new road is open to traffic has not been made clear.2、用it 作形式主语的主语从句注：以下几种特殊情况必须用it作形式主语：⑴ It is + adj. + that 从句常见的形容词有：necessary，right，likely，wrong，important，certain，clear，obvious，strange 等。
→ It is likely that there will be a snowstorm tomorrow.⑵ It is + noun + that 从句常接这种句型的名词有：a pity, a shame, good news, a fact, an honor, a wonder, no wonder 等。
→ It is a pity that you didn’t attend the lecture [讲座] yesterday.⑶It is + 过去分词常见的分词有：said, heard, reported, decided, suggested, advised, ordered, thought, considered, pointed out, well known, hoped, turned out 等词→ It is said that the professor has already succeeded in carrying out this experiment.⑷ It + 特殊动词+ that从句常用于这种结构的动词有：seem，happen（碰巧），appear，occur 等。
→ It seems to me that you object to the plan.It happened that I didn’t take any money with me.⑸It doesn’t matter how/whether…结构中的主语从句→It doesn’t matter whether he is wrong or not.三、宾语从句1、动词的宾语从句⑴大多数动词都可以带有宾语从句→ We all expect that they will win this match.常见的动词有：hope, tell, say, know, think, consider, imagine, hear, expect, suppose, guess 等。
⑵有些“动词+副词”结构也可带宾语从句。
→ I have found out that all the tickets for the concert have been sold out.⑶可以运用形式宾语it的宾语从句：①动词find, feel, think, consider, make, believe 等后有宾语补足语时，需要用it 作形式宾语而讲that宾语从句后置。
→ I think it necessary that we take plenty of hot water every day.I have made it a rule that I keep diaries.② 动词hate, take, have, see to等词在带宾语从句时习惯上需要在宾语从句前加it。
▲（若宾语从句是“WH”系列引导，其后有to be短语作宾补，则不可以用it替代。
）→ I take it that you will agree with us.We all consider what you said to be unbelievable.2、介词的宾语从句⑴一般情况下，介词后面只能用“WH”系列连接词来引导的宾语从句。
→ We are talking abo ut whether we admit students into our club.▲用that引导从句作介词宾语时，需要用形式宾语it替代，然后将that从句发在最后。
→ You may depend on it that I shall always help you.⑵偶尔的情况下，except, but, besides, in四个介词后面可接that引导的宾语从句→ I know nothing about my new neighbor expect that he used to work in a company.I prefer his plan to yours in that I think it is more practical. (in that 表示原因)He would have failed but that you helped him. (but that 要不是，若非)3、形容词的宾语从句⑴sure, certain, glad, pleased, happy, afraid, surprised, satisfied, sorry等表示“情感”色彩的形容词后也可以带宾语从句。
→ He is sure that they will make it in spite of the terrible weather.⑵当主句中的谓语动词是think, say, guess, suppose, suggest, believe, feel, consider时，宾语从句的引导词表示疑问时，需要放在句首。
→ Who do you think the public might choose as their favorite singer this year?4、if和whether在宾语从句中用法的区别▲ Whether和if在作“是否”讲时：Ⅰ在下列几种情况下只能用whether。
⑴当被引导的宾语从句置于句首时。
→ Whether they will join in the winter camp I don’t care.⑵引导的宾语从句作介词的宾语时。
→ We are talking about whether he will come next week.⑶从句中有“or not”时。
→ I don’t care whether the work will take long or not.⑷引导词后接动词不定式时。
→ I am just wondering whether to stay for another hour or just start off right away.⑸当从句部分用if 引导时，容易出现歧义时。
→ Let me know whether you can come.*(此句话中若出现if，则不能判定if表示的含义为“是否”还是“如果”，容易有歧义。
) Ⅱ在动词ask, know, wonder, 词后，只能用if。
5、不可省略that的宾语从句⑴当that作learn, suggest, explain, agree, wonder, prove, mean, state, feel, hold等动词的宾语时，常不省略。
→ I have learnt that most of the students who are interested in Chinese take interest in English.⑵当宾语从句比较长时，that不省略。
→ We all think that what the public is badly in need of is nothing but the development of economy.(我们大家都认为所急需的不是别的正是经济发展.)⑶当主句状语置于宾语从句之前时。
→ I realized at once that I had done wrong immediately she told me all about this.⑷当宾语从句的状语或状语从句置于其句首时。
→ He told us that, if we could all come to help out, the whole situation would be looking up.⑸当主句谓语动词（或非谓语动词）与宾语从句之间有插入语时。
→ Whe n Marx got to England, he found, however, that his English was so limited that he could n’t go on with his common affairs.⑹当一个动词带有两个或两个以上并列的宾语从句时，此时第一个that可以省略，第二个that不可以。
→ Then he began to talk to us about the French language, saying (that) it w as the most beautiful tongue in the world, and that we must keep it among is and never forget it.⑺当宾语从句的主语是this，that，或this，that为主语的定语时。
