专题十 名词性从句

what 考查表语从句引导词。句意:不过,真相正如所料——这里从来没有其他人,只有我和尼克,还有这片安静的森林。“is”后接表语从句,从句中缺少主语,指物,用what引导,what在从句中作主语,意为“……的事情”。故填what。
2.(2023·新高考Ⅱ卷)This is ________ they need an English trainer.
why 考查表语从句。句意:这就是他们需要英语培训师的原因。分析句子结构可知,空处引导表语从句,从句中结构完整,应该用连接副词连接,前文提到需要培训师的原因,此处是表达“这就是他们需要英语培训师的原因”之意,应用why引导表语从句。故填why。
3.(2023·全国乙卷)It seems that TV programmes have helped change ________ people think about cooking.
what 考查宾语从句。句意:似乎电视节目帮助改变了人们对烹饪的看法。change 后的宾语从句缺少宾语,故填 what。
4.(2021·全国乙卷)Also,it gives our parents more time to do ________ they like and it improves the family relationship.
what 考查宾语从句。do后面缺宾语,所以后面应该是宾语从句,连词在从句中充当宾语。句意:这给了父母更多的时间去做他们喜欢的事情,并改善了家庭关系。故填what。
5.(2021·新高考Ⅰ卷)________ is so breathtaking about the experience is the out-of-this-world scenes.
What 考查主语从句。句意为:这次经历的令人惊叹之处在于这绝世的景色。此处是主语从句,主语从句部分缺主语,故填What。

8.(2020·天津卷)The student completed this experiment to make come true ________ Professor Joseph had said.
what 考查名词性从句。句意:为了使约瑟夫教授所说的成为现实,这个学生完成了这个实验。what Professor Joseph had said作make的宾语从句。引导宾语从句,在从句中作said的宾语,像这样兼作成分是what的特点。(该句中宾语补足语come true被前置。)
9.(2019·江苏卷)Scientists have obtained more evidence ________ plastic is finding its way into the human body.
that 考查同位语从句。句意:科学家已经获得更多证据,塑料正在进入人们的体内。从句不缺句子成分,且与evidence指代的是同一事件,用that引导同位语从句。

what 考查宾语从句。句意:我们选择这家宾馆是因为一晚上的住宿费降到了20美元,这是该宾馆过去要价的一半。“half of ________ it used to charge”是$20的同位语,即原来价格的一半是$20;另外,of后跟名词或名词短语构成介宾短语,所以,这里是宾语从句;宾语从句中的charge后面缺少宾语,所以用what来引导宾语从句,并充当宾语从句中的宾语。

考点一 名词性从句的引导词that与what的区别
引导词
句法功能
省略情况
that
不作任何句子成分
引导宾语从句有时可以省略
what
主语、宾语、表语、定语
不能省略
It is by no means clear what the president can do to end the strike.
总统会采取什么措施来结束这次罢工还不清楚。
考点二 whether与if的区别
只能用whether,不能用if的情况:
(1)在主语从句、表语从句、介词之后的宾语从句及同位语从句中;
(2)后面直接跟动词不定式;
(3)与or not连用;
(4)引导让步状语从句时。
Everyone in the village is very friendly.It doesn't matter whether you have lived there for a short or a long time.
村子里的每个人都很友好。无论你在哪里住多久都没关系。(此句为主语从句,故只能使用whether)
考点三 “疑问词+ever”引导的名词性从句与“no matter+疑问词”引导的状语从句的区别
1.“疑问词+ever”可引导名词性从句,在主语从句中都充当一定的成分。
who只在从句中作成分,而whoever在主从句中都作成分。引导名词性从句的whoever相当于anybody who;whomever则在主从句中都作宾语;whichever相当于anyone which。
2.“疑问词+ever”还可引导让步状语从句。
3.“no matter+疑问词”只能引导让步状语从句。
As many as five courses are provided,and you are free to choose whichever suits you best.
提供了多达五门的课程,你可以任意选择最适合你的一门。(宾语从句)
You can come whenever/no matter when you like.无论什么时候,只要你想来,你就来。(状语从句)
考点四 名词性从句连接副词when,where,how,why的判断
在判断名词性从句引导词的使用时,要兼顾句意和句子成分,如果句子缺成分,则缺什么补什么,当然要满足句意要求,使句子符合语境。
考点五 同位语从句与定语从句的区别
1.从语法角度来看,引导同位语从句的that是连词,在从句中不充当任何成分;而引导定语从句的that是关系代词,它除了起引导从句的语法作用之外,还要在从句中充当句子成分,主要是作主语或宾语。
2.从先行词的词性来看,同位语从句的先行词大都为抽象名词,而定语从句的先行词可以是名词,也可以是代词。
3.从可否省略来看,同位语从句的that一般不可以省略,但是定语从句中的关系代词如果在从句中充当宾语,在非正式用语中常常可以将关系代词that省略。
4.从引导词来看,同位语从句有时也可以用whether来引导,但是定语从句不用whether来引导。
5.引导同位语从句的关联词是对先行词的具体内容进行进一步的解释说明,与先行词不存在指代关系;而引导定语从句的关系代词或关系副词不但在从句中充当成分,而且与其修饰的先行词指代的是同一个人或者事物。
I made a promise to myself that this year,my first year in high school,would be different.
我给自己做出承诺:今年,是我上高中的第一年,将会与以往不同。(that引导promise的同位语从句)
This is the museum that you visited a few days ago.
这就是你几天前参观的那个博物馆。(that引导定语从句)
【温馨提示】 名词性从句的时态和语序
(1)名词性从句一律使用陈述句语序。
(2)在宾语从句中,当主句动词是现在时态时,宾语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)时,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、过去完成时等;当从句表示的是客观真理、科学原理、自然现象时,则从句仍用现在时态。
1.—I wonder ________ Mary has kept her figure after all these years.
—By working out every day.
how 句意:——我想知道这么些年来玛丽是如何保持体形的。——通过每天锻炼身体。“________ Mary has kept her figure after all these years”为宾语从句,该从句中缺少方式状语,故填how。
2.You have to know ________ you're going if you are to plan the best way of getting there.
where 句意:如果你要计划到那里的最好路线,你就得知道你将要往哪儿走。“________ you're going”为宾语从句,该从句中缺少地点状语,故填where。
3.Reading her biography,I was lost in admiration for ________ Doris Lessing had achieved in literature.

9.Pick yourself up.Courage is doing ________ you're afraid to do.
what 句意:振作起来,勇气就是去做你害怕去做的事情。分析题干可知doing后为宾语从句,从句中缺作宾语的连接词。在宾语从句中,what可以作主语或宾语,所以填what。

4.their 考查代词。句意:维修工人把绳子系在腰上,在墙壁陡峭的一侧铺上水泥,其他人则拿着绳子支撑。分析句子可知,此处修饰名词,所以要用形容词性物主代词。故填their。

8.which 考查定语从句。句意:因为这条路太陡了,必须用驴子和骡子来运送砖块,每块砖块重达150公斤。分析句子可知,本句是非限制性定语从句,先行词指物,关系代词在从句中作主语,所以此处要填which。

【语篇解读】 本文是一篇说明文。研究表明,大自然芳香的气味能改善幸福感。
1.resting 考查非谓语动词。句意:花时间在户外是一种全方位的感官体验,无尽的天空,美丽的森林,风的声音和温暖的阳光照在你的脸上。sunrays与空白处所填词在逻辑上是主谓关系,故用现在分词作后置定语。故填resting。
2.enjoyable 考查形容词。句意:除了大自然令人愉快的景象、声音和感觉之外,大自然熟悉的气味也同样具有吸引力。空白处所填词在文中作定语修饰“sights,sounds and sensations”,故填形容词enjoyable。

7.linked 考查非谓语动词。句意:他们还发现,人们在没有气味的地方感觉更安定,这种结果可能与没有城市难闻的气味有关,比如污染。此处是“with+宾语+宾补”复合结构作状语,link和宾语this result之间是被动关系,应用过去分词作宾补。故填linked。
8.be applied 考查动词语态。句意:该研究的合著者Jessica Fisher博士指出,这些结果可以应用于未来的实践。“these results”是“apply”动作的承受者,故用被动语态;情态动词could在此用于表示“可能性”,后接动词原形。故填be applied。
9.it 考查代词。句意:在他看来,当谈到享受在树林里远足或在开阔的天空下野餐时,不仅要睁大眼睛和耳朵,还要睁大鼻子。when it comes to...为固定句型,意为“谈到,涉及……”。故填it。
