才推迟的吗

文化节上,你分享了很多关于你的国家的有趣的事情。 (2022浙江1月)
用法归纳
①强调句型的基本句式结构为:　　 is/was+被强调部分+who/that+其他部分。被强调
部分指人时用who或that,指事或物时用that。
②强调句型的一般疑问句句式为:　　　　　 +被强调部分+who/that+其他部分
③强调句型的特殊疑问句句式为:特殊疑问词+is/was it+that+其他部分
④强调句型如果强调的是原因状语从句,从句只能用　　　　　 引导,而不能用since或
as。
⑤对not...until...进行强调的句式为:It is/was not until...+　　 +其他部分。在强调句型中只
用until而不用till。
It
Is/Was it
because
that
特别提醒
(1)判断某个句子是不是强调句型的方法:将句子中的It is/was和who/that同时省去,能还原成
完整的句子且句子意思依然完整的就是强调句型。
(2)当强调的是主语时,who/that后的谓语动词应和被强调的主语保持人称和数的一致。
结构拓展
强调谓语应用“do/does/did+动词原形”的形式。

宾语
主语从句
　　主语从句,即在主从复合句中充当主语成分的句子。
一、主语从句的引导词
引导主语从句的词主要有:
从属连词:that、whether、if
连接代词:who、whoever、whose、whom、whomever、what、whatever、which、whichever
连接副词:when、where、why、how
必备语法 情景破
(一)从属连词
情景导学
Whether we will go on an outing tomorrow remains uncertain.我们明天是否会外出游玩仍不确
定。
That he finished writing the composition in such a short time surprised us all.他在如此短的时间
内写完作文使我们所有人都十分惊讶。
用法归纳
(1)从属连词引导主语从句时,在从句中只起引导从句的作用,不充当句子成分,但不能省略。
(2)that没有实际意义,whether/if意为“①　　 ”。
特别提醒
if不可以引导位于句首的主语从句,if引导主语从句时,只能用it作形式主语而把主语从句后
置。whether后可紧跟or not,if不可以。
It is uncertain if our data will be used for much more serious acts, such as telecommunication
fraud.我们的数据是否会被用于如电信诈骗等更严重的行为还不确定。
是否
(二)连接代词
1.who、whom、what、which、whose引导的主语从句
情景导学
Who will be our monitor hasn't been decided yet.还没有决定谁会成为我们的班长。
Whom we study for is a question of great importance.我们为谁而学是个很重要的问题。
What is so breathtaking about the experience is the out-of-this-world scenes.这次经历的令人惊
叹的地方在于这非凡的景色。 (2021新高考Ⅰ)
It is still uncertain which he will choose/whom he went together with/whose book it is.还不确定
他会选择哪一个/他和谁一起去的/这是谁的书。
用法归纳
连接代词引导主语从句时,不仅起引导从句的作用,还在从句中作②　　 、宾语、表
语、定语等句子成分。what引导主语从句时表示“……的事(物);什么”。
2.whatever、whoever、whomever、whichever引导的主语从句
情景导学
Whoever says that is a liar.=Anyone who says that is a liar.说那话的人都是骗子。
Whatever he does from now on has nothing to do with me.=Anything that he does from now on
has nothing to do with me.从现在起他做的任何事都与我无关。
主语
用法归纳
(1)whoever引导主语从句时相当于“③　　 +who”, 意为“任何……的人”。
(2)whatever引导主语从句时相当于“anything+that”,意为“任何……的事(物)”。what与
whatever有时可互换,二者的区别是whatever语气更强烈。
(3)whomever与whichever引导主语从句的情况并不常见。whomever与whoever的意义与用法
同理。whichever用来表示选择,通常前文会提供选择范围。
anyone
(三)连接副词
情景导学
When we arrive doesn't matter.我们什么时候到不重要。
Why he refused us wasn't quite clear.他为什么拒绝我们不是很清楚。
Where I spend my summer holiday is no business of yours.我在哪里过暑假不关你的事。
用法归纳
　　连接副词引导主语从句时,不仅起引导作用,还在从句中作④　　 成分。连接副词引
导主语从句时,保留了其疑问词的意思,即why、when、how、where分别意为“为什么”
“什么时候”“怎样”“在/到哪里”。
状语
二、it作形式主语代替主语从句的情况
情景导学
It is very likely that they will hold a meeting.他们很有可能会举行一次会议。
It is important that we should all attend the meeting.重要的是我们都应该参加会议。
It is reported that the film is well received outside China.据报道,这部电影在国外很受欢迎。
(2020江苏)
It is said that he has gone to Shanghai.(=He is said to have gone to Shanghai.)据说他已经去上海
了。
It happened that the two cheats were there.(=The two cheats happened to be there.)那两个骗子碰
巧在那里。
It is a pity that we won't be able to go to the south to spend our summer vacation.真遗憾,我们将
不能去南方过我们的暑假。
用法归纳
(1)为了防止句子头重脚轻,通常用⑤　　 作形式主语,放在句首的位置,而将主语从句后
置。
(2)常用it作形式主语的句式:
It+be+过去分词+that从句
It+系动词+名词(短语)+that从句
It+系动词+形容词(短语)+that从句
It+特殊动词或动词短语(matters/happens/turns out/...)+that从句
it
特别提醒
在“It+be+形容词/过去分词+that...”句型中,当形容词是important、necessary、strange等时,
谓语用“should+动词原形”形式,should可以省略;当过去分词是advised、suggested、or-
dered、required、demanded等时,谓语用“should+动词原形”形式,should可以省略。
三、主语从句的语序和主谓一致
(一)主语从句的语序
情景导学
Who will go is not important.谁将去不重要。
When he will come is not known.他何时来还不知道。
用法归纳
　　主语从句总是用⑥　　 语序。
陈述句
(二)含有主语从句的主从复合句的主谓一致问题
情景导学
What we need is time.我们需要的是时间。
What we need are good doctors.我们需要的是好的医生。
What I say and think are none of your business.我说什么、想什么与你无关。
Whether they would support us was a problem.他们是否会支持我们还是一个问题。
用法归纳
　　主语从句作主语时,谓语动词一般用⑦　　 形式,但what引导的主语从句意义上表示
复数或what从句有两个(以上的)动词,是表示复数意义的并列结构时,谓语动词用复数形式。
