1、1专题 2 名词性从句框架结构图名词性从句(主语从句、宾语从句、表语从句、同位语从句 )中的连接词名词性从句中的连接词有从属连词 that/whether/if等，连接代词what/who/which/whose/whatever/whoever/whomever/whichever等 ， 连 接 副 词where/when/why/how/wherever/whenever等。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

2、 we dont have enough money.The report that there will be a severe storm in the northern area is false.(2)一般情况下，宾语从句中的引导词 that可省略，但在以下几种情况中 that一般不省略：当 that从句和主句谓语动词之间有插入语时；有多个 that引导的从句时，第一个that可以省略，而其他的 that常不可省略；介词 except，but，besides，in 等后跟that引导的宾语从句时；当 when，who，what，where，why，how 等引导的从句与 that引导的

3、从句作主句谓语动词的并列宾语时。He judged that，because he was a child，he did not understand wine.The reason lies in that she works harder than the others do.Everyone knew what happened and that she was worried.2(3)that和 what的区别。that引导名词性从句时，在主从句中不担当任何句子成分，也没有任何含义；而 what引导名词性从句时，在主从句中都要充当一定的句子成分，what 可以分解成定语从句中的“先行词

4、关系代词” ，即常说的“先行词that/which/who” 。Its a shame that he has made such a mistake.I will do what I can (do) to help him.(4)同位语从句与定语从句中 that的区别。同位语从句中的连接词 that只起连接作用，在从句中不担当任何句子成分；而定语从句中的关系代词 that在句中作宾语或主语，与先行词有修饰关系。如果句子是同位语从句，就应用连接词 that而不能用 which。同位语从句一般放在表具体含义的名词后解释说明名词的含义或内容，如以下名词：news，fact，suggestion，

5、truth，plan，belief，doubt，possibility，idea 等，而定语从句只是对先行词的限定和修饰。They expressed the hope that they would come to visit China again.(同位语从句)The hope that they expressed is that they would come to visit China again.(定语从句) 2.whether和 if的用法：(1)whether和 if在宾语从句中可以互换，但是作介词宾语时连接词一般用 whether。It all depends on wh

6、ether they will come back.(2)后面直接跟 or not 时用 whether。I didnt know whether or not he had arrived in Wuhan.(3)主语从句、表语从句中只能用 whether。Whether the meeting will be put off has not been decided yet.The question is whether they have so much money.(4)whether可以引导同位语从句，用以说明前面的名词的内容，if 则不能。We ought to discuss c

7、arefully the question whether we can do it or not.(5)whether常与 or连用表示一种选择，if 不能这样用；whether 也可与动词不定式连用，但 if不能。The question of whether they are male or female is not important.I have not decided whether to go or not.(6)宾语从句位于句首时或者宾语从句提前时用 whether不用 if。Thank you，but whether Ill be free Im not sure at t

8、he moment.(7)whether可引导一个让步状语从句表示“不管” 、 “无论” ，而 if不能。Whether he comes or not，we will begin our party on time.33.“疑问词-ever”和“no matter疑问词”的区别：(1)“疑问词-ever”可引导名词性从句，在主从句中要充当一定的成分。Whoever breaks the rule must be punished.You can choose whatever you like in the shop.(2)“疑问词-ever”还可引导让步状语从句。Whoever break

9、s the rule，he must be punished.Whatever you do，you must do it well.(3)“no matter疑问词”只能引导让步状语从句。No matter what you do，you must put your heart into it.No matter who comes late，he must be punished.4.when和 where引导的同位语从句与定语从句的区别：when和 where前面的名词若是表示时间、地点的名词，则 when和 where引导的是定语从句，否则为同位语从句。This is the plac

10、e where the accident happened.(定语从句)They put forward the question where they could get the money.(同位语从句)主语从句的核心考点1.主语从句在复合句中充当主语，大多数主语从句都可以用 it作形式主语而把主语从句置于句尾。2.that引导主语从句时可用 it作形式主语，that 不可省；what 引导的主语从句表示“的东西”时，一般不用 it作形式主语；whatever，whoever，whichever 一般也不用 it作形式主语。That she will succeed is certain.

11、It is certain that she will succeed.What he needs is more experience.常见的 it替代 that引导的主语从句的句式主要有以下几种：(1)It系动词形容词(necessary，right，likely，unlikely，wrong，important，certain，clear，obvious，strange，normal 等)that 从句It is certain that most of the farmers have brought in more money by all means.(2)Itbe名词(短语)(a

12、 pity，a shame，good news，a fact，an honour，a wonder，no wonder 等)that 从句Its no wonder that youve achieved so much success.(3)Itbe过去分词(said，told，heard，reported，decided，suggested，advised，ordered，remembered4，thought，considered，well-known，announced 等)that 从句It is said that the professor has already succeed

13、ed in carrying out the experiment.(4)It特殊动词(seem，appear，happen，matter)that 从句It happened to me that I had been away when he called.注意：(1)在“It is necessary/important/strange/natural.that 从句”结构中，从句谓语常用“(should)动词原形” 。(2)在“Itbesuggested/advised/ordered/requested/insisted/required.that从句”结构中，从句谓语应用“(sho

14、uld)动词原形” 。宾语从句的核心考点1.动词的宾语从句(1)大多数动词(hope，tell，say 等)可以带宾语从句。We all expect that they will win，for members of their team are stronger.I dont think you are right.I dont suppose he cares，does he?(2)动词 find，feel，think，consider，make，believe 等后有宾语补足语时，则常用 it作形式宾语而将 that宾语从句后置。I think it necessary that we

15、 take plenty of boiled water every day.(3)有些动词(短语)带宾语从句时习惯上需要在宾语从句前加 it。这类动词(短语)有hate，enjoy，like，love，dislike，see to 等。I hate it when they talk with their mouths full.2.一般情况下介词后只能用 wh-类连接词引导宾语从句。We are talking about whether we admit students into our club.注意：(1)where 引导的从句有时也可用作介词的宾语。We could see th

16、e temple quite clearly from where we lived.(2)that引导的从句作介词的宾语是很少有的，只有在 except，in，but 等介词后偶尔可能用到。Your composition is quite good except that the organization is a bit loose.(3)sure，certain，glad，pleased，happy，surprised 等表示“情感”的形容词后也可带宾语从句。Im sure that they will make it in spite of the terrible weather.

17、表语从句的核心考点1.主句的主语是 idea，advice，suggestion，order，request，requirement 等名词时，5表语从句的谓语应用虚拟语气，即“(should)动词原形”的形式。His suggestion is that we (should) change our course.2.主语为名词 reason时，表语从句中的连接词要用 that，而不用 why或 because。The reason for such a serious accident is that the driver was too careless and drank too mu

18、ch.3.because，as if，as though，as，like 等连接词也可引导表语从句。He has lung disease.That is because he has been smoking too much.同位语从句的核心考点同位语从句是用以解释说明某一名词的内容的从句。1.能接同位语从句的名词有：belief，fact，hope，idea，doubt，news，conclusion，suggestion，problem，order，answer，decision，explanation，information，thought 等。2.同位语从句一般用 that引导，但

19、也可以用连接代词(what，which，who)、连接副词(when，where，why，how)或 whether引导。I have no idea what has happened to him.3.有时同位语从句不紧跟在它所说明的某个名词后，而是被别的词隔开。The story goes that William Tell did kill the king with that sword.1.语序问题(误)These pictures show you what does our village look like.(正)These pictures show you what ou

20、r village looks like.宾语从句的语序应用陈述语序，而不是特殊疑问句的语序。(误)Do you think which of these is the most useful invention?(正)Which of these do you think is the most useful invention?在疑问句中，宾语从句的连接词应担当特殊疑问词的角色位于句首。2.what和 that的运用(误)America was that was first called “India” by Columbus.(正)America was what was first c

21、alled “India” by Columbus.在名词性从句中，连接词 that既不作任何句子成分，也没有意义；而连接代词 what则相反，它既充当从句的主干成分也有其自身的意义。另外，我们可以把 what解释为：the名词that/which。3.whether和 if的运用(误)If well hold the party has not been decided yet.6(正)Whether well hold the party has not been decided yet.whether适用于任何情况；if(作“是否”讲)仅限于动词宾语从句中，但 discuss，decid

22、e等动词后的宾语从句除外。4.连接词的使用易受汉语干扰(误)The reason why I was late is because I was trapped in the traffic jam.(正)The reason why I was late is that I was trapped in the traffic jam.第一句通过提取简化可得出：The reason is because.在英语中显然造成了重复现象。考向 1 宾语从句中的连接词.单句语法填空1.The gold medal will be awarded to whoever wins the first p

23、lace in the bicycle race.(2018天津)解析 句意为：无论谁获得自行车比赛第一名，金牌将授予他。分析句子可知，空格处作to的宾语，同时在后面的从句中作主语，再根据句意可知，从句主语指人，且意为“无论谁” ，故用 whoever。2.Im not sure who/which is more frightened，me or the female gorilla(大猩猩) that suddenly appears out of nowhere.(2018全国)解析 句意为：我不确定谁(哪一个)更害怕，我还是突然出现的雌性大猩猩。此处为宾语从句，空格处表示“谁”或“哪一

24、个” ，故用 who/which。3.As natural architects， the Pueblo Indians figured out exactly how thick the adobe walls needed to be to make the cycle work on most days.(2015全国)解析 分析句子结构可知，这是一个宾语从句。根据形容词 thick及结构可知，这里的意思是印第安人算出土坯墙的确切厚度。空格后为形容词，因此空格上应用副词，故填how。.单句改错(每小题仅有 1处错误)1.My uncle is the owner of a restaur

25、ant close to I live.(2016全国)thatwhere解析 由句子结构可知，介词 to之后为宾语从句，而宾语从句中缺少地点状语，故用where引导。2.After looking at the toy for some time，he turned around and found 或wherethatwhere his parents were missing.(2015全国)解析 句意为：他转过身发现父母不见了。由句意可知，宾语从句句意完整且不缺少成分，所以应该用 that引导从句或省略。7考向 2 表语从句中的连接词.单句语法填空1.Without his suppo

26、rt，we wouldnt be where we are now.(2018北京)解析 句意为：假如没有他的支持，我们就不会取得现在的成就。 “ we are now”是表语 从 句 ， 结 合 句 子 的 意 思 可 知 ， 此 处 表 面 意 思 是 指 我 们 所 处 的 位 置 ， 故 该 从 句 应用 where引 导。2.This is what my father has taught meto always face difficulties and hope for the best.(2018北京)解析 句意为：这就是我父亲教我的总是要直面困难，并且抱最大的希望。 “ m

27、y father has taught me”是表语从句，该空在从句中作 teach的直接宾语，且表示“父亲教我的道理” ，故该从句应用 what引导。3.40 grams of meat per day is what people should consume in order to stay fit.(2018北京海淀区二模)解析 句意为：为了保持健康，人们每天应该消耗 40克肉。 “ people should consume”是表语从句，该从句中 consume缺少宾语，且表示“所需消耗的东西” ，故要用what引导该从句。4.Earthquakes worry people a l

28、ot.The reason is that we often do not know when they are coming.People can not prepare for it. (2017河南中原名校联考)解析 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。.单句改错(仅有 1处错误)I believe hard work is it takes to accomplish my goal.(2018河北石家庄二thatwhat中一模)解析 本句中 what引导表语从句，并在句中作动词 take的宾语。that 引导表语从句不作句子成分。考向 3 主语从句和同位语

31、 can.(2017江西上饶模拟)解析 分析句子结构可知，设空处引导主语从句，且从句中 learn后缺少宾语，故填What。.单句改错(仅有 1处错误)Its a great pity we wont be able to finish the task on time.(2017唐whatthat山模拟)解析 It 作形式主语，真正的主语为 that引导的从句。.单句语法填空1.How we understand things has a lot to do with what we feel.2.A ship in harbor is safe，but thats not what shi
