2022高考人教版英语一轮复习学案：第九讲　依据句子成分和结构突破名词性从句 WORD版含答案.doc

1、第九讲依据句子成分和结构突破名词性从句编者按：所谓名词性从句，就是把完整句子当作名词来使用，使之在另一个句子中充当某种成分。一般来说，名词在句中主要充当4种成分：主语、宾语、表语和同位语，于是便有了常说的4种名词性从句：主语从句、宾语从句、表语从句和同位语从句。相当于名词作用的句子有3类：陈述句、一般疑问句和特殊疑问句。因此，名词性从句可简单概括为这样一句话：名词性从句就是用3种句子分别充当另外一个句子的4种句子成分。这便构成了名词性从句的本质特征。 真题集训明考点1(2020浙江7月高考)Over thousands of years, they began to depend less o

2、n could be hunted or gathered from the wild, and more on animals they had raised and crops they had sown. 解析：what分析句子结构可知，介词on后是宾语从句，从句中缺少主语，且表示“的事物”，应用what引导。2(2019全国卷)While they are rare north of 88， there is evidence they range all the way across the Arctic, and as far south as James Bay in Canad

4、out of nowhere.解析：who分析句子结构可知，空格处作从句的主语，根据后面的“me or the female gorilla”可知，作者把自己和大猩猩作对比，表示“我不知道我和大猩猩谁更害怕”，故填who。5(2018北京高考改编)This is my father has taught me to always face difficulties and hope for the best.解析：what句意：这就是父亲教给我的永远面对困难并且寄予最大的希望。表语从句中动词taught缺少直接宾语， 且表示“的东西”，故填what。6(2018北京高考改编)Without h

6、 way to get here, which is we arrived.解析：how句意：坐船是到达这里唯一的方式，我们就是这样来的。how 引导表语从句，作方式状语。语法精析知规则一、从属连词that, whether与if引导的名词性从句(一)that引导的名词性从句that引导名词性从句时本身无意义，只起连接作用，也不在句中作任何成分。它引导的名词性从句结构和意义都完整，往往用于陈述事实。在引导主语从句、表语从句和同位语从句时，that不能省略。在引导宾语从句时，在口语和非正式文体中，that可省略。但下列情况下，that不可省略：1that从句作介词的宾语；I dont know

7、exactly where he lives, except that its somewhere out in the wilds.他具体住在哪里我不是很清楚，只知道是远离城市的边远地区。2that引导的从句位于句首时；That the earth goes around the sun is known to us all.众所周知，地球围着太阳转。3宾语从句和主句之间有插入语时；We hope, on the contrary, that he will stay at home with us.恰恰相反，我们希望他和我们待在家里。4动词后有多个that引导的宾语从句时，只有第一个tha

8、t可省略，从第二个从句开始that不可省略；He told me (that) he had to leave and that he would be back soon.他告诉我他得离开并且很快就会回来。5it作形式宾语时，that引导的宾语从句后置时，that往往不可省略。He has made it clear that the meeting will not be postponed.他清楚地表明会议不会被推迟。(二)that引导主语从句时可用it作形式主语的四大句式1Itbe形容词(necessary, right, likely, unlikely, wrong, import

9、ant, certain, clear, obvious, strange, normal等)that从句It isnt likely that I should accept such an offer as that.我不可能接受像那样的帮助。2Itbe名词(短语)(a pity, a shame, good news, a fact, an honour, a wonder, no wonder等)that从句Its no wonder that he didnt want to go.难怪他不想去。3Itbe过去分词(said, told, heard, reported, decid

10、ed, suggested, advised, ordered, remembered, thought, considered, wellknown, announced等)that从句It is decided that the meeting has been put off until next Monday.会议被推迟到下周一已经定下来了。名师指津在“Itbesuggested/advised/ordered/requested/insisted/required .that从句”结构中，从句谓语应用“(should)动词原形”。It is suggested that you (s

11、hould) spend more time in studying English.建议你花更多的时间学习英语。4It特殊动词或短语(seem, appear, happen, matter, turn out, occur to, make no difference等)that从句It suddenly occurred to her that Joe was afraid of beingalone.她突然想到乔害怕独自一个人待着。(三)whether与if的用法1用whether或if均可的情况(1)whether可引导各种名词性从句。引导大部分动词后的宾语从句时，两者均可。(2)i

12、t作形式主语，且主语从句在句末时，两者均可引导主语从句。Its uncertain whether/if hell come this evening.他今天晚上是否会来还不确定。2用whether而不用if的情况(1)主语从句和宾语从句置于句首时；Whether we can have clean drinking water lies in what effective measures will be taken by the government about water pollution.我们能否有干净的饮用水取决于政府将采取什么样的有效措施处理水污染问题。(2)引导表语从句和同位语

13、从句时；The problem is whether the air pollution can be controlled.问题是空气污染能否被控制住。He asked me the question whether we should give money to the homeless.他问了我我们是否该给无家可归者钱的问题。(3)引导介词的宾语从句时；It depends on whether we have enough time.这取决于我们是否有充足的时间。(4)引导词与or not连用时；I dont know whether or not the report is true

14、.I dont know whether the report is true or not.我不知道这个报道是否是真的。(5)引导词后接to do时；They dont know whether to go there.他们不知道是否去那里。(6)有些动词如leave, put, discuss, decide等后的宾语从句；We discussed whether we should hold a meeting.我们讨论了我们是否应召开一个会议。(7)避免用if引导产生歧义。Let me know whether you are coming to our party.让我知道你是否来参

15、加我们的宴会。二、连接代词与连接副词引导的名词性从句1连接代词引导的名词性从句连接代词who, whom, whose, what, which等不但起连接作用，也在从句中作名词或代词所作的成分，如主语、表语、宾语、定语等。缺少连接代词，从句不完整。What struck me most in the movie was the fathers deep love for his son.这部影片中最打动我的是父亲对他儿子深深的爱。What worries us most is who let out the secret.最令我们担忧的是谁泄漏了秘密。2连接副词引导的名词性从句连接副词whe

16、n, where, why, how等不但起连接作用，也在从句中作状语，表示时间、地点、原因和方式等。He didnt tell me when we would meet again.他没告诉我什么时候我们再见面。Go and get your coat. Its where you left it.去把你的大衣拿来。它就在你原来放的地方。3“疑问词ever”引导的名词性从句“疑问词ever”引导名词性从句时，有词义，并且在从句中充当一定的句子成分。Whoever breaks the law should be punished.无论谁触犯法律都应该受到惩罚。Wherever he goe

17、s makes his parents worry.他无论去哪儿父母都担心。名师指津“疑问词ever”还可以引导让步状语从句，但“no matter疑问词”只能引导让步状语从句，不能用来引导名词性从句。Whatever (No matter what) you do, you must do it well.无论你做什么，都必须做好。三、名词性从句易错点1that和what的区别that引导名词性从句时，在主从句中不充当任何句子成分，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/whic

18、h/who”。Its a shame that he has made such a mistake.真遗憾，他犯了这样一个错误。I will do what I can (do) to help him.我将尽我所能帮助他。2同位语从句与定语从句的区别判断是定语从句还是同位语从句可以用“加词”的方法，即在名词和从句之间加入一个be动词，如果句子意思成立，则是同位语从句，否则，则是定语从句。试比较：The notice that the meeting had to be put off was true.(同位语从句)The notice was that the meeting had t

19、o be put off.The notice that he read just now was true.(定语从句)应用落实通方法一、单句语法填空1(2021烟台模拟)Along with this, Max has traveled to Africa several times to donate equipment and coach the kids, developing Angels at Bat into what it is today.2(2021北京模拟)The most pleasant thing of the rainy season is that one c

22、题技法语法填空解题“3步骤”1根据两句之间的意义和逻辑关系，或者根据句子结构判断是否是名词性从句。2一旦判断是名词性从句，就根据名词性从句中缺少什么句子成分来确定选用什么连接词。若从句中缺少主语、宾语或表语，用连接代词；若缺少状语就用连接副词。3如果不缺少成分则要考虑意思是否完整，是否需要用whether/if; 如果不缺少成分且意思完整用that。二、单句改错1But the most important thing is what the number of private cars should be put under control.whatthat2Recently the stu

23、dents in our class have had a heated discussion on if people should keep pets at home in cities.ifwhether3Reading exposes you to new words, and you will see why those words are used.whyhow4If we are in the habit of raising doubts as to if what we are told is true, we can find the correct answer and

30、river didnt admit the fact 9 he was driving too fast at the turning.The police doubted 10 what he said was true and decided to make a further investigation.语篇解读：本文是一篇新闻报道。文章报道了一起交通事故。1that句意：据报道，今天早上在罗马大街的拐角处发生了一起交通事故。“It be过去分词that.”为固定句式，其中it为形式主语，that从句是真正的主语。2what句意：没人知道当时究竟发生了什么。what引导宾语从句作saw的

31、宾语，从句中缺少主语且表示事物，故用what引导。3Who句意：谁应对这一事故负责仍然在调查中。“ 3 will be responsible for the accident”为主语从句，该从句中缺少主语且表示“人”，故用who引导。4whether句意：警察不能确定司机是否有罪。根据题干中的uncertain可知设空处表示“是否”，介词后不能由if来引导宾语从句，所以此处应用whether。5What句意：现在警察应做的就是他们必须弄清楚事故的起因。what引导主语从句，在从句中作do的宾语。6that“ 6 they must find out what led to the accid
