1、考点20 宾语从句高考频度：【命题解读】名词性从句是高考的热点，对于名词性从句考纲要求掌握以下内容：掌握主语从句、宾语从句、表语从句的基本用法，了解同位语从句的基本用法。要求考生在复习备考中应该掌握名词性从句的基本用法；一些易混引导词的辨析；句子的语序、否定前移；名词性从句和定语从句、状语从句的辨析等。【命题预测】预计2021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。【复习建议】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。考向一 名词性从句连
2、接词的用法名词性从句的连接词主要有以下几种：从属连词that/whether/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 dont have enough money.The report that there
3、 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引导的从句作主句谓语动词的并列宾语时。He judged that，because he was a child，he d
4、id not understand wine.The reason lies in that she works harder than the others do.Everyone knew what happened and that she was worried.(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关系代词，即常说的先行词that。Its a shame that he has made such a mistake.
5、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，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 ho
6、pe that they would come to visit China again.(同位语从句)The hope 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 whether they will come back.(2)后面直接跟or not 时用whether。I didnt know whether or not he had arr
7、ived 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 carefully 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
8、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)间接宾语位于句首时或者间接宾语提前时用whether不用if。Thank you，but whether Ill be free Im not sure at the 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
9、.3.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 breaks 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 m
10、ust 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，否则则为同位语从句。They put forward the question where they could get the money.(同位语从句)This is the place where the accident happened.(定语从句)5.名词性从句中that不宜省略的几种情
11、况宾语从句或表语从句中that有时可以省略，但在以下情况时，that不宜省略。 （1）当动词后带有两个并列的宾语从句时，引入第二个从句的连词that不可省略。如： The teacher told the students (that) they should hand in their homework the next day and that the homework must be signed names by their parents. 老师告诉学生他们要在第二天交上作业，并且作业必须由家长签名。 （2）当that前面有插入语时，that不宜省略。如： Little Alice
12、didn't know, I'm sure, that her sister was going to America. 我确信，小艾丽斯不知道她的姐姐很快就要去美国了。 （3）省略答语中，that宾语从句单独出现时，that不可省略。如： What did he say? 他说了什么 That he would visit the Great Wall. (他说)他将会参观长城。 （4）当主句的状语部分位于that 宾语从句之前时，that不宜省略。如： Jane realized at once that she must do with it herself. 珍立刻意识
13、到她必须亲自处理那件事。(如省略that，at once也可能修饰从句，是表示立刻意识到，还是表示立刻去处理，较为含糊) （5） 当that 宾语从句中的状语部分位于从句的前部时，that不宜省略。如： Tom promised that if he could earn as much as 500 dollars in this month, he would buy a computer for his brother. 汤姆许下诺言，如果他在这个月里能够赚到500美元，他就给他的弟弟买台电脑。 （6）当that 宾语从句是双宾语中的直接宾语时，that一般不宜省略。如： I will

15、the chance to go abroad for further study. 玛丽下定决心努力学习以获得奖学金资格，这样她就有机会出国深造了。 （9）当that 宾语从句前有 it作其形式宾语时，that不可省略。如： We think it important that college students should master at least one foreign language.我们认为大学生至少掌握一门外语是很重要的。 （10）当引导同位语从句时，that一般不可省略，尤其当that与先行词处于分割情况时。如： He heard the news that his te
16、am had won. 他听到了他的队获胜的消息。 There is a feeling in me that they are cheating me. 我有一种感觉他们在骗我。 （11）当that 宾语从句的主语是非谓语动词或是主语从句时，that不可省略。如： The doctor said that taking exercise was the best way of losing weight. 医生说运动是最好的减肥方式。 考向二 宾语从句【难点梳理】1）宾语从句主要跟在动词、介词和某些形容词之后。I wish hat he woud understand me. 我希望他能理解
17、我。Whether we can succeed depends on how well we cooperate.我们能否成功取决于我们合作得怎么样。注意：(1)一般情况下介词后只能接wh-类连接词引导的宾语从句。He'll talk to us about what happened in the classroom.他将给我们讲述课堂上发生的事情。(2) in, but, except等少数几个介词后可接由that引导的宾语从句，但此时介词和that已形成固定搭配，即in that因为, but that要不是, except that除了。The high income tax
18、 is harmful in that it may discourage people from trying to earn more.个人所得税高是有害的，因为它可能使人们不愿意努力赚更多的钱。He would have failed but that you helped him.若不是你帮助他，他会失败的。Im afraid that Ive made a mistake. 恐怕我犯了一个错误。2）引导宾语从句的连接词主要有：连接词：that，whether，if等连接代词：what，who，whose，whatever，whichever，whoever等连接副词：when，whe

20、 请让我知道你是否能来。（2）作介词的宾语从句时。We are interested in whether you will attend the meeting. 我们对你是否参加会议感兴趣。2. 连接代词what，who，whose，whatever，whichever，whoever等引导She asked me whose handwriting was the best in the class. 她问我班上谁的书法最好。Ill just say whatever comes into my mind. 我想到什么就说什么。3. 连接副词when，where，why，how等引导Do
21、 you know when the ancient Olympic Games began? 你知道古代的奥运会是什么时间开始的吗?Ive been thinking about how we can make the newspaper more interesting. 我一直在考虑如何使我们的报纸更用趣。4. 宾语从句的语序在宾语从句中要用陈述句语序。He asked me when we could set out the next day. 他问我第二天什么时候可以出发。Did you find out where she lost her car? 你查出她在哪里丢的车了吗?5.
22、 宾语从句的时态（1）当主句的谓语动词是一般现在时时，其宾语从句的时态可以是任何适当的时态。She says (that) she works from Monday to Friday. 她说她周一至周五上班。(从句是一般现在时)she says (that) she will leave a message on his desk. 她说她要在他桌子上留个便条。(从句是一般将来时)She says (that) she has never been to Mount Emei. 她说她从来没有去过峨眉山。(从句是现在完成时)（2）当主句的谓语动词是一般过去时时，其宾语从句的时态一般要用适当

24、ficult if we put our hearts into it. 老师告诉我们世上无难事，只怕有心人。He said that light travels much faster than sound. 他说光比声音传播得快。注意：在使用宾语从句时需要注意下面几点：动词find，feel，think，consider，make，believe，guess，suppose，assume等后有宾语补足语时，则需要用it作形式宾语，而将that宾语从句后置。I think it necessary that we take plenty of boiled water every day.
25、我认为每天多喝开水是有必要的。I have made it a rule that I keep diaries. 我每天写日记成了惯例。hate，like，take，owe，have，take for granted等表示喜欢；痛恨；认为的动词或动词短语和see to表示注意，留意后有宾语补足语时，需要用it作形式宾语而将宾语从句后置。I hate it when they talk with their mouth full of food. 我讨厌他们满嘴食物说话。When you start the engine, you must see to it that the car is

27、I dont think I know you. 我想我并不认识你。I dont believe he will come. 我相信他不会来。【巧学妙记】宾语从句的用法速记口诀宾语从句须注意，几点事项应牢记。一是关键引导词，不同句子词相异。陈述句子用that；一般疑问是否（if，whether）替；特殊问句更好办，引导还用疑问词。二是时态常变化，主句不同从句异。主句若为现在时，从句时态应看意；主句若为过去时，从句时态向前移。三是语序要记清，从句永保陈述序。1.（2020·天津卷7月·单项选择）15. The student completed this experiment
