【命题预测】
预计2019年高考对名词性从句的考查仍然不会单纯地考查其语法结构，而是将其融入一定的语境中来考查考生的实际综合运用能力。
【名师指导】
1. 掌握宾语从句的用法；
※2. 了解同位语从句的用法；
3. 掌握表语从句的用法；
4. 掌握主语从句的用法；
5. 如何正确选择引导词。
1．that引导主语从句时，没有具体意思，不充当句子成分，只是起标志性的作用，但that不能省略。what引导时，在从句中充当成分，且有意义。
◆It is true that the cllege will take in mre new students. 这所大学将招收更多的新生是真的。
2．whether连接主语从句时，表示怀疑，不能省略，意为“是否”，在句首时不能用if替换。
◆(重庆高考)It is still under discussin whether the ld bus statin shuld be replaced with a mdern htel r nt. 旧汽车站是否应该被重建为现代化的宾馆仍然在商讨中。
3．连接代词、连接副词引导主语从句时不能省略，并在从句中充当句子成分。
◆It was never clear why the man hadn’t reprted the accident sner.
这个人为什么没有尽快报告这个事故，还不清楚。
4．主语从句要用陈述语序，即主谓语序。
eq \a\vs4\al()
(1)用it作形式主语的常用句型有：
①It＋系动词＋形容词(necessary/right/likely/unlikely/wrng/imprtant/certain等)＋that从句
②It＋be＋名词(短语)(a pity/a shame/n wnder等)＋that从句
③It＋be＋过去分词(said/tld/reprted/decided等)＋that从句
④It＋特殊动词(seems，appears，happens，matters)＋that从句
◆It is a pity that I missed the party held last night.
很遗憾我错过了昨晚举行的聚会。
◆It is reprted that the accident was caused by carelessness.
据报道，该事故源于(司机的)粗心(驾驶)。
(2)在It is necessary/imprtant/suggested/advised/rdered＋that从句结构中，从句用“(shuld＋)动词原形”。
[典例] (2015·广东高考语法填空)Nw it ccurred t him ____________ his farm had much ptential and that the death f the cw was a bit f luck.
that 解析： 固定句型“it ccurred t sb.＋that从句”表示“某人突然想到”，it是形式主语，真正的主语是that引导的从句。
单句语法填空
1．(2016·北京高考语法填空)Yur supprt is imprtant t ur wrk.____________ yu can d helps.
Whatever 解析： 句意：您的支持对我们的工作很重要。无论您能做什么都会有所帮助。____________yu can d作句子的主语，是主语从句。主语从句中缺少动词d的宾语，而且指代做的事情，结合句意可知填Whatever。
2．(2017·山东师大附中一模)His favrite fd is fried snacks and sft drinks. It is n surprise____________lsing weight is just his dream.
that 解析： 句意：他最喜欢的食物是油炸类小吃和软饮料。减肥只是他的梦想一点都不令人吃惊。It是形式主语，真正的主语是that引导的主语从句。从句中结构及句意完整，故用that引导。
3．(陕西高考)It remains t be seen____________the newly frmed cmmittee’s plicy can be put int practice.
whether 解析： 句意：新组建的委员会制定的政策是否能实施还有待观察。It是形式主语，设空处引导主语从句，用whether符合句意。
1．that连接宾语从句时通常可以省略(但多个并列的宾语从句中只能省略第一个that)，没有具体的意思，不充当句子成分，只是起连接作用。what引导时，在从句中充当成分，且有意义。
◆(全国卷Ⅰ)I’m writing t tell yu that my uncle Li Ming is ging t yur city fr a cnference.
我写信是想告诉你我叔叔李明要去你的城市开会。
2．在whether/if连接的宾语从句中，whether/if意为“是否”，但在whether…r nt结构中，或者whether引导的宾语从句作介词的宾语时，以及whether＋t d结构中和whether引导的从句作少数动词(如leave，put，discuss，dubt，knw等)的宾语时，只能用whether，不能用if来替换。
◆We’ve ffered her the jb，but I dn’t knw whether she’ll accept it. 我们已经为她提供了这份工作，但我不知道她是否会接受。
◆I dn’t knw whether t leave r nt.
我不知道是否要离开。
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。
◆Our teachers always tell us t believe in what we d and wh we are if we want t succeed.
老师总是告诉我们，如果想要成功，就要相信我们所做的事情以及我们是谁。
4．有些动词或动词短语，如like，hate，appreciate，depend n，see t等，一般不直接跟从句，需要借助it。
◆Yu may depend n it that she will g with yu.
你可以相信她会与你一起去。
5．当主句的主语是第一人称时，在think，believe，suppse，expect等动词后的宾语从句若是否定的，就运用否定转移，将否定词转移到主句谓语动词上。
◆I dn’t believe she will attend the meeting.
我认为她不会来参加该会议。
6．it作形式宾语，真正的宾语后置，常用此种结构的及物动词有find，make，think，feel，cnsider等。
◆I find it imprtant that we shuld keep calm in danger.
我发现我们在危险中保持镇静是很重要的。
7．不论主句为何种句型，宾语从句都用陈述语序。
[典例] (2016·全国卷甲短文改错)My classmates and I are talking abut hw t d during the hliday.
hw→what 解析： 句意：我和我的同学正在谈论假期做什么。根据句意可知，abut后的宾语从句表达的意思为“做什么”，而不是“怎么做”，故用what。
单句语法填空
1．(2017·贵州贵阳联考)T ur astnishment, we saw a light and sme peple in a cabin. Jim was t frightened t g n but I felt curius, wndering ____________was happening.
what 解析： 句意：令我们惊讶的是，我们看到在小屋内有一束光和一些人。吉姆太害怕了，不敢继续往前，但是我觉得很好奇，想知道发生了什么事。设空处引导宾语从句，并在从句中作主语，表示事物，故用what引导。
2．(2017·石家庄一模)Finally, keep in mind____________there are many things that can’t be learnt immediately, and never be frustrated when yu fail in ne r tw exams.
that 解析： 考查宾语从句。动词短语keep in mind后是一个宾语从句，且从句中不缺少成分，因此用that引导。
3．(2017·福建安溪模拟)Success partially depends n ____________yu have the patience t d simple things perfectly.
whether 解析： 句意：成功部分取决于你是否有耐心把简单的事情做得完美。设空处引导宾语从句，作介词n的宾语，意为“是否”，故填whether。
1．that连接表语从句时从句为一个句意完整的陈述句，that不能省略，没有具体的意思，不充当句子成分，只是起连接作用。
◆(全国卷Ⅰ)The end result is that we feel like we can’t fcus r that we’re fcused n the wrng things.
最后的结果是我们感觉我们没能集中注意力或我们关注的是错误的事情。
2．whether连接表语从句时从句来源于一般疑问句，为一个句意完整、语气不确定的陈述句。whether不能省略，意为“是否”，不能用if替换。
◆His questin is whether they can be friends.
他的问题是他们能否成为朋友。
3．连接代词、连接副词引导表语从句时连接词不能省略，并在从句中充当句子成分。
◆I’d like t start my wn business—that’s what I’d d if I had the mney.
如果我有钱，我会自己做买卖，那就是我想做的事情。
4．表语从句要用陈述语序，即主谓语序。
eq \a\vs4\al()
常见的表语从句句型：
(1)It lks/seems as if…好像……；仿佛……
(2)This is because…这是因为……(强调原因)
(3)The reasn why…is that………的原因是……
(4)That is why…那就是……的原因(强调结果)
(5)The questin/prblem is whether/when/where…问题是……
(6)His dream/suggestin/aim/purpse is that…
他的梦想/建议/目标/目的是……
(7)what从句＋be＋that从句
◆What surprised us mst was that he came late again.
最让我们惊讶的是他又迟到了。
[典例] (2016·北京高考单项填空)The mst pleasant thing f the rainy seasn is____________ne can be entirely free frm dust.
that 解析： 句意：雨季最令人愉快的事情是人们可以完全远离尘埃的烦扰。这是一个复合句，主句的主语是The mst pleasant thing f the rainy seasn，is是系动词，________ ne can be entirely free frm dust作表语，是表语从句。从句成分及意思完整，只是缺少连接词，故填that。
单句语法填空
1．(2015·陕西高考短文改错)My nly mistake was ____________ I drpped sme n the flr when I was packing them up.
that 解析： 引导表语从句，that在从句中不作成分，只起到连接作用。
2．(四川高考)Grandma pinted t the hspital and said，“That’s ____________I was brn.”
where 解析： 句意：“那就是我出生的地方。”奶奶指着那家医院对我说。前面提到了医院，所以设空处应该是表地点，故用where引导该表语从句，并在从句中作地点状语。
3．(2017·河南中原名校联考)Earthquakes wrry peple a lt. The reasn is ____________we ften d nt knw when they are cming.Peple can nt prepare fr it.
that 解析： 句意：地震让人们很担忧。原因是我们通常不知道它们什么时候发生。人们没法做准备。设空处引导表语从句，从句的结构和意义完整，所以用that引导。
※
在名词性从句中，同位语从句是比较难理解的一种从句，虽然在近几年全国卷中没有直接考查过，但需要注意掌握其以下可能考查的方向。
1．that连接同位语从句时从句为一个句意完整的陈述句，that不能省略，没有具体的意思，不充当句子成分，只起连接作用。另外，注意定语从句中的引导词that也要在从句中作成分(主语、宾语)。
The news that I passed the exam is true.
我通过了考试这一消息是真的。
2．连接代词、连接副词引导同位语从句时连接词不能省略，并在从句中充当句子成分。
◆I have n idea where the jurnalist culd have gt his infrmatin frm.
我不知道那个记者从哪里得到的消息。
[典例] (2016·天津高考单项填空)The manager put frward a suggestin____________ we shuld have an assistant. There is t much wrk t d.
that 解析： 根据句意可知“经理提出了一个建议”，建议的内容是“我们应该有个助手”，设空后的从句解释说明suggestin的内容，且设空处在从句中不作任何成分，也不表示任何含义，应用that。
单句语法填空
1．There is slid evidence ____________ watching 3D mvies can have sme side effects n the viewers.
that 解析： 考查同位语从句。句意：有确凿证据考查同位语从句。证明观看3D电影会对观看者有一些副作用。抽象名词为evidence证据，that引导同位语从句，只起引导的作用，在从句中不作任何成分，无具体意义。
2．(2017·河北石家庄质检)Finally I want t express my hpe ____________ all the yunger fellws can make full use f time.
that 解析： hpe后从句是同位语从句，设空处在从句中没有任何意义，故填that。

【参考答案】
1. 解析：根据句式． the adbe walls needed t be(换个角度 the adbe walls needed t be ________ thick)可以看出，这里需要与动词短语figured ut所相呼应的程度副词，修饰形容词thick，所以程度副词为hw，表示多么的意思。
答案：hw

15. 解析：句意为：坦白地说，如果货物能够尽快被运送，他们将会非常感激。wuld appreciate it if...表示“如果……将不胜感激”，it作形式宾语，if引导的是宾语从句。
16. 解析：句意为：“媒体”这个词基本上指的是我们通常称作报纸、 杂志、 收音机和电视的东西。what在名词性从句中的意思是“……的人/物”，可以作主语、宾语或表语。refer t中的t是介词，后接宾语从句，what在从句中作call的双宾语中的一个，故填what。
答案：what
17. 解析：句意为：一个关于我们是否应该在课堂上给学生机会产生新想法以培养学生的创新思维能力的问题已经出现了。根据句意，此处应表示“是否”，故填whether引导同位语从句。
