主語從句
  主語從句,即在主從復合句中充當主語成分的句子。
一、主語從句的引導詞
引導主語從句的詞主要有:
從屬連詞:that、whether、if
連接代詞:who、whoever、whose、whom、whomever、what、whatever、which、whichever
連接副詞:when、where、why、how
必備語法 情景破
(一)從屬連詞
情景導學
Whether we will go on an outing tomorrow remains uncertain.我們明天是否會外出游玩仍不確
定。
That he finished writing the composition in such a short time surprised us all.他在如此短的時間
內寫完作文使我們所有人都十分驚訝。
用法歸納
(1)從屬連詞引導主語從句時,在從句中只起引導從句的作用,不充當句子成分,但不能省略。
(2)that沒有實際意義,whether/if意為“①   ”。
特別提醒
if不可以引導位于句首的主語從句,if引導主語從句時,只能用it作形式主語而把主語從句后
置。whether后可緊跟or not,if不可以。
It is uncertain if our data will be used for much more serious acts, such as telecommunication
fraud.我們的數據是否會被用于如電信詐騙等更嚴重的行為還不確定。
是否
(二)連接代詞
1.who、whom、what、which、whose引導的主語從句
情景導學
Who will be our monitor hasn't been decided yet.還沒有決定誰會成為我們的班長。
Whom we study for is a question of great importance.我們為誰而學是個很重要的問題。
What is so breathtaking about the experience is the out-of-this-world scenes.這次經歷的令人驚
嘆的地方在于這非凡的景色。 (2021新高考Ⅰ)
It is still uncertain which he will choose/whom he went together with/whose book it is.還不確定
他會選擇哪一個/他和誰一起去的/這是誰的書。
用法歸納
連接代詞引導主語從句時,不僅起引導從句的作用,還在從句中作②   、賓語、表
語、定語等句子成分。what引導主語從句時表示“……的事(物);什么”。
2.whatever、whoever、whomever、whichever引導的主語從句
情景導學
Whoever says that is a liar.=Anyone who says that is a liar.說那話的人都是騙子。
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.從現在起他做的任何事都與我無關。
主語
用法歸納
(1)whoever引導主語從句時相當于“③   +who”, 意為“任何……的人”。
(2)whatever引導主語從句時相當于“anything+that”,意為“任何……的事(物)”。what與
whatever有時可互換,二者的區別是whatever語氣更強烈。
(3)whomever與whichever引導主語從句的情況并不常見。whomever與whoever的意義與用法
同理。whichever用來表示選擇,通常前文會提供選擇范圍。
anyone
(三)連接副詞
情景導學
When we arrive doesn't matter.我們什么時候到不重要。
Why he refused us wasn't quite clear.他為什么拒絕我們不是很清楚。
Where I spend my summer holiday is no business of yours.我在哪里過暑假不關你的事。
用法歸納
  連接副詞引導主語從句時,不僅起引導作用,還在從句中作④   成分。連接副詞引
導主語從句時,保留了其疑問詞的意思,即why、when、how、where分別意為“為什么”
“什么時候”“怎樣”“在/到哪里”。
狀語
二、it作形式主語代替主語從句的情況
情景導學
It is very likely that they will hold a meeting.他們很有可能會舉行一次會議。
It is important that we should all attend the meeting.重要的是我們都應該參加會議。

巧在那里。
It is a pity that we won't be able to go to the south to spend our summer vacation.真遺憾,我們將
不能去南方過我們的暑假。
用法歸納
(1)為了防止句子頭重腳輕,通常用⑤   作形式主語,放在句首的位置,而將主語從句后
置。
(2)常用it作形式主語的句式:
It+be+過去分詞+that從句
It+系動詞+名詞(短語)+that從句
It+系動詞+形容詞(短語)+that從句
It+特殊動詞或動詞短語(matters/happens/turns out/...)+that從句
it
特別提醒
在“It+be+形容詞/過去分詞+that...”句型中,當形容詞是important、necessary、strange等時,
謂語用“should+動詞原形”形式,should可以省略;當過去分詞是advised、suggested、or-
dered、required、demanded等時,謂語用“should+動詞原形”形式,should可以省略。
三、主語從句的語序和主謂一致
(一)主語從句的語序
情景導學
Who will go is not important.誰將去不重要。
When he will come is not known.他何時來還不知道。
用法歸納
  主語從句總是用⑥   語序。
陳述句
(二)含有主語從句的主從復合句的主謂一致問題
