1. 求主語從句例句,越簡單越好
一、主語從句定義：在句子中擔當主語的是一個從句，這個從句就叫做主語從句。
二、主語從句例句：1. What surprised me most was that the little girl could play the violin so well. 2. Who will go to the concert is not known. 3. That she was chosen made us very happy. 4. Whether she will come or not is still a question. 5. Which book they will choose is still unknown. 6. When we shall hold our sports meet is not decided. 7. It's strange that he knows nothing about it. 8. It is a pity that she has made such a mistake. 9. It is said that President Jingo will visit our school next week.三、主語從句的引導詞 主語從句通常由連詞that和whether、連接代詞或連接副詞以及關系代詞型what引導。1. that引導 That he is still alive is a wonder. 他還活著，真是奇跡。
That we shall be late is certain. 我們要晚了，這是確定無疑的。That he should have ignored the working class was natural. 他忽視工人階級是很自然的。
That she is still alive is a consolation. 她還活著是使人感到寬慰的。That she became an artist may have been due to her father's influence. 她成為畫家可能是受她父親的影響。
That you are coming to London is the best news I have heard this long time. 你將來倫敦是好久以來我聽到的最好消息。That she was chosen made a tremendous stir in her village. 她被挑選上，在她村 子里引起很大轟動。
2. whether引導 Whether it will do us harm remains to be seen. 是否對我們有害還要看一看。Whether they would support us was a problem. 他們是否會支持我們還是一個問題。
3. 連接代詞引導 Whoever is top from wins the game when two matched players meet. 兩強相爭勇者勝。Whichever (of you) comes in first will receive a prize. 無論（你們）誰先到都可以得獎。
Whichever you want is yours. 你要哪個哪個就是你的。4. 連接副詞引導 When we arrive doesn't matter. 什麼時候到沒有關系。
How it was done was a mystery. 這是怎樣做的是一個謎。How this happended is not clear to anyone. 這件事怎樣發生的，誰也不清楚。
How many people we are to invite is still a question. 邀請多少人還是一個問題。Where I spend my summer is no business of yours. 我在哪里過暑假不關你的事。
5. 關系代詞型what引導 What we need is money. 我們需要的是錢。What I want to know is this. 我想知道的就是這一點。
What's done is done. 事已成定局。What he says is not important. 他說的話并不重要。
What I am telling you is mere impressions. 我和你說的都不過是一些印象而已。What make the river more beautiful are the lotus plants growing in the water. 為河水增色的是水里的荷花。
What you need is a good-sized canvas bag. 你需要的是一個比較大的帆布袋。What I am afraid of is their taking him to Portugal. 我擔心的是他們把他帶到葡萄牙去。
What struck me was that they have all suffered a lot. 給我很深印象的是他們都受過很多苦。四、主語從句與形式主語it 有時為了考慮句子平衡，通常在主語從句處使用形式主語it，而將真正的主語從句移至句末。
這分三種情況：（1） 對于以連詞that引導的主語從句，通常用形式主語代主語從句：It's a pity that he didn't come. 很遺憾他沒來。It is important that he should know about this. 他必須知道此事。
It's vital that we be present. 我們出席是至關重要的。It was intended that you be the candidate. 大家的意圖是讓你當候選人。
It is important that this mission not fail. 這項使命不失敗至關重要。It is essential that a meeting be convened this week. 本周開一次會非常重要。
It is appropriate that this tax be abolished. 廢除這個稅是恰當的。It's unfair that so many people should lose their jobs. 竟有這麼多人失業這是不公平的。
It's amazing that she should have said nothing about it. 她竟未談及此事令人驚訝。It's unthinkable that they should deny my request. 他們竟然拒絕我的請求，這是不可思議的。
That they should refuse to sign the petition required great courage. 他們拒絕在請愿書上簽字這是需要很大勇氣的。（2） 對于以連接代詞（副詞）引導的主語從句，可以使用形式主語代主語從句，也可直接在句首使用主語從句：Whether they would support us was a problem. 他們是否會支持我們還是一個問題。
It was a problem whether they would support us. 他們是否會支持我們還是一個問題。It remains to be seen whether it will do us harm or good. 它對我們是利是害，還得看看再說。
（3） 對關系代詞型what引導的主語從句，通常直接將主語從句放在句首。如：What we need is money. 我們需要的是錢。
What I want to know is this. 我想知道的就是這一點。有時也可將助用形式主語。
如：It is clear enough what he meant. 他是什麼意思很清楚。（4） 如果句子是疑問句，則必須用帶形式主語it的結構：Is it true that he is the girl's father？ 他是那女孩的父親，是真的嗎？How is it that you are late again？ 你怎麼又遲到了？五、連詞that的省。
2. 關于主語從句造句
it's time that we begin our work.(it's time 。..是“正是做什麼的時間”的意思)
it's important that this application is filled.
it's said that Mike has been killed.(it's said是“據說。。。。”的句型)
it's working that we persuade him.（我們勸說他似乎正在起作用）——這里要注意，不及務動詞是沒有被動態的，因此只能夠用ing形勢
3. 用主語從句翻譯以下句子
1. I don't care whether or not he comes.It's none of my bussiness whether he comesor not.
2. It is not important who will go there.
3. It is all right what she does.
4. It is said that Mr. Green has arrived in Beijing.
5. No wonder that his English has made great progress。
望采納 ，thx
4. 有關主語從句
定義：如果一個句子在復合句中充當一個主語，那麼這個句子就是主語從句.
第一部分：常規主語從句，即句子在復合句中充當一個主語
(1)That he finished writing the composition in such a short time surprised us all.
(2)Whether we will go for an outing tomorrow remains unknown.
(3)Who will be our monitor has't been decided yet.
(4) Whom we must study for is a question of great importance.
(5)What caused the accident remains unknown.
(6)Whatever you did is right.
(7)Whose watch was lost is unknown.
(8)What we need is time.
(9)What we need are good doctors.
小結：
(1)引導主語從句連詞有that,whether,who,what,whatever等
(2)連詞位于句首不能省略
(3)主語從句大多數情況下視為單三，但也有例外，如例9
第二部分：為了防止句子頭重腳輕，通常把形式主語it放在主語位置，真正主語擱置于句末
(1)It is certain that he will win the match.
(2)It is true that he has made a very important discovery in chemistry.
(3)It is very likely that they will hold a meeting.
(4)It is strange that he should do that.
(5)It is important that we all should attend the meeting.
(6)It is strange that the man should have stuck to his silly ideas.
(7)It is a pity that we won't be able to go to the south to spend our summer vacation.
(8)It is still a mystery what caused the accident.
(9)It is said that he has gone to shanghai.(=He is said to have gone to shanghai)
(10)It is known to all that the gun powder was first invented by the Chinese.
(11)It is suggested that the work should be done with great care.
(12)It seems that he has seen the film.(=He seems to have seen the film)
(13)It happened that the two cheats were there. (=The two cheats happened to be there)
小結：
(1)以that 引出的主語從句，常以形式主語it引導. It is +形容詞/名詞/某些動詞ed + that 從句.
(2) 在有些that從句中要用虛擬語氣 （should+do/should+have done）例句4,5,6,11.
5. 主語從句例子
1 主語從句的時態：不受主句的時態影響和限制。
(1)That he finished writing the composition in such a short time surprised us all.
(2)Whether we will go for an outing tomorrow remains unknown.
(3)Who will be our monitor hasn't been decided yet.
(4) Whom we must study for is a question of great importance.
(5)What caused the accident remains unknown.
(6)Whatever you did is right.
(7)Whose watch was lost is unknown.
(8)What we need is time.
2 為了防止句子頭重腳輕，通常把形式主語it放在主語位置，真正主語擱置于句末
(1)It is certain that he will win the match.
(2)It is true that he has made a very important discovery in chemistry.
(3)It is very likely that they will hold a meeting.
(4)It is strange that he should do that.
