2. 構成：關聯詞+簡單句
3. 引導主語從句的關聯詞有三類：
(1) 從屬連詞that。 如：That they were in truth sisters was clear from the facial resemblance between them.
很明顯，她們確是親姐妹，她們的臉型很相似。
(2) 從屬連詞whether。如：

How this happened is not clear to anyone. 這事怎樣發生的，誰也不清楚。
Whoever comes is welcome. 不論誰來都歡迎。
Wherever you are is my home ---- my only home. 你所在的任何地方就是我的家----我唯一的家。
解釋：
1. 主語從句能用it作形式上的主語。常以it作形式主語的句型有：
A. It+be+形容詞(obvious, true, natural, surprising, good, wonderful, funny, possible, likely, certain, probable, etc.)+that從句。如：
It is certain that she will do well in her exam. 毫無疑問她考試成績會很好。
It is probable that he told her everything. 很可能他把一切都告訴她了。
B. It+be+名詞詞組(no wonder, an honour, a good thing, a pity, no surprise, etc.)+that從句。如：
It’s a pity that we can’t go. 很遺憾我們不能去。
It’s no surprise that our team should have won the game. 我們沒贏這場比賽真意外。
C. It+be+過去分詞(said, reported, thought, expected, decided, announced, arranged, etc.)+that從句。如：
It is said that Mr. Green has arrived in Beijing. 據說格林先生已經到了北京。
It is reported that China has sent another man-made earth satellite into orbit.
據報道中國又成功地發射了一顆人造地球衛星。
D. It+seem, happen等不及物動詞及短語+that從句。如：
It seems that Alice is not coming to the party at all. Alice似乎不來參加晚會。
It happened that I was out that day. 碰巧我那天外出了。
E. It+doesn’t matter (makes no difference, etc.)+連接代詞或連接副詞引起的主語從句。如：
It doesn’t matter whether she will come or not. 她是否來這無關緊要。
It makes no difference where we shall have the meeting. 我們在哪里開會毫無區別。
F. 當that引導的主語從句出現在疑問句中時，要以it作形式主語，而把主語從句后置。如：
Is it true that the scientist will give us a lecture next week? 下周那位科學家將給我們作報告是真的嗎?
Does it matter much that they will not come tomorrow? 他們明天不來很要緊嗎?
G. 當主語從句出現在感嘆句中時，要以it作形式主語，而把主語從句后置。如：
How strange it is that the children are so quiet! 孩子們這么安靜真奇怪!
2.注意連接代詞whoever, whatever, whichever等引導主語從句的含義
Whoever comes will be welcome. (whoever=the person who) 來的人將受到歡迎。
Whatever he did was right. (whatever=the thing that) 他所做的事情是正確的。
Whichever of you comes in will receive a prize. (whichever=anyone of you who) 你們當中不論哪個進來將會得到獎
二、表語從句
1. 定義：用作表語的從句叫做表語從句。
2. 構成：關聯詞+簡單句
3. 引導表語從句的關聯詞的種類：
(1) 從屬連詞that。如：
The trouble is that I have lost his address. 麻煩是我把他的地址丟了。
(2) 從屬連詞whether, as, as if。如：
He looked just as he had looked ten years before. 他看起來還與十年前一樣。
The question is whether they will be able to help us. 問題是他們是否能幫我們。
注：從屬連詞if一般不用來引導表語從句，但as if卻可引導表語從句，如：
All this was over twenty years ago, but it's as if it was only yesterday.
這都是20多年前的事了，但宛如昨天一樣。
能跟表語從句的謂語動詞一般為系動詞be, seem, look等。如：
It looked as if it was going to rain. 看起來天要下雨了。
(3)連接代詞who, whom, whose, what, which, whoever, whatever, whichever
連接副詞 where, when, how, why。
如：The problem is who we can get to replace her. 問題是我們能找到誰去替換她呢。
The question is how he did it. 問題是他是如何做此事的。
That was what she did this morning on reaching the attic. 那就是她今晨上了閣樓干的。
解釋：
1. 連詞because可引導表語從句。如：
I think it is because you are doing too much. 我想這是因為你做得太多。
2. 在一些表示“建議、勸說、命令”的名詞后面的表語從句中，謂語動詞用虛擬語氣。should+動詞原形表示，should可省略。如：
My suggestion is that we (should) start early tomorrow. 我的建議是我們明天一早就出發。
三、賓語從句
1. 定義：用作賓語的從句叫賓語從句。
2. 構成：關聯詞+簡單句
3. 引導賓語從句的關聯詞有三類：
(1) 從屬連詞that。如：
He told us that he felt ill. 他對我們說他感到不舒服。
I know he has returned. 我知道他已經回來了。
注： that在引導賓語從句時也并不是任何情況下都可以省略。在以下情況下，that不能省略。
1. Everybody could see what happened and that Tom was frightened.(and連接兩個賓語從句，that賓語從句放在and的后面時，that不能省略。)
大家都會看出所發生的事情并知道Tom非常害怕。
2.I know nothing about him except that he is from the south.(that引導的賓語從句作介詞賓語時，that不能省略。)
對他我一無所知，只知道他是南方人。
3.That he ever said such a thing I simply don’t believe. (that從句位于句首時，that不可省略。)
我簡直不相信他曾說過這樣的話。
4. We decided, in view of his special circumstances, that we would admit him for a probationary period. (主句謂語動詞與that從句之間有插入語，that不可省略。)
鑒于他的特殊情況，我們決定應允他一段試用期。
(2)從屬連詞if/whether。如：
I doubt whether he will succeed. 我懷疑他是否會成功。
I don’t know if you can help me. 我不知道你能否幫助我。
(3)連接代詞who, whom, whose, what, which, whoever, whatever, whichever
連接副詞 where, when, how, why。
如：
Who or what he was, Martin never learned.
他是什么人?他是干什么的?馬丁根本不知道。
I wonder what he’s writing to me about. 我不知道他要給我寫信說什么事。
I’ll tell you why I asked you to come. 我會告訴你我為什么要你來。
You may do what you will. 你可做任何你想做的事。
(1) 介詞賓語從句
賓語從句也可用作介詞的賓語。如：
He was deeply displeased by what had occurred that day.
他對那天發生的事感到很不快。
I walked over to where she sat. 我走向她坐的地方。
I am curious as to what he will say. 我很想知道他要說什么。
Your success will largely depend upon what you do and how you do it.
你是否成功將主要取決于你做什么和怎樣做。
有時介詞可以省略。如：
I don’t care (for) who marries him. 我不管誰跟他結婚。
Be careful (as to) how you do that. 你要注意做這件事的方式。
解釋：
1.如果賓語從句后還有賓語補足語，則用it作形式賓語，而將賓語從句后置。如：
We thought it strange that Xiao Wang did not come yesterday.
我們認為小王昨天沒來是奇怪的。
He has made it clear that he will not give in.
他已表明他不會屈服。
2.作介詞的賓語：連詞that引導的名詞性從句很少作介詞的賓語，只用在except, but, in后。其他一些介詞的賓語從句如果由連詞that引導，則需用it先行一步，作形式賓語。如：
He is a good student except that he is careless.
他是一個好學生，只是有點粗心。
You may rely on it that I shall help you. 你可以指望我會幫助你的。
介詞賓語不可以用which來引導，而要用what來引導。如：
Are you sorry for what you've done?
你為你所做的一切感到內疚嗎?
3.某些形容詞或過去分詞后常接賓語從句，這類形容詞或過去分詞有sure, glad, certain, pleased, happy, afraid, surprised, satisfied等，連詞that可省略。如：
I am not sure what I ought to do.
我不能確定我該做什么。
I'm afraid you don't understand what I said.
恐怕你沒領會我說的意思。
I'm surprised that I didn't see all that before.
我好奇怪，我以前沒看到過。
Mother was very pleased her daughter had passed the exams.
媽媽為她的女兒通過了考試而感到高興。
4.連詞whether (…or not)或if引導的賓語從句
if和whether引導的賓語從句可以互換使用，但whether常和or not連用，if一般不與or not連用。如：
I wonder whether it is true or not. 我不知它是真是假。
用if引導賓語從句如果會引起歧義，應避免使用if而用wheter。試比較：
Please let me know if you want to go.
Please let me know whether you want to go.
if從句可理解為賓語從句，意為“請告訴我你是否想去”;此句又可理解為條件狀語從句意為“如果你想去的話，請告訴我一聲”。
5.賓語從句的否定轉移。在think, believe, suppose, expect等動詞后的賓語從句，有時謂語盡管是否定意思，卻不用否定形式，而將think等動詞變為否定形式。如：
I don’t think you are right. 我認為你錯了。
I don’t believe they have finished their work yet. 我相信他們還未完成他們的工作。
I don’t suppose he cares, does he? 我想他不在意，是嗎?
6. 賓語從句的時態變化規律：
(1) 當主句是一般現在時態時，從句可根據需要用任何時態。
(2) 當主句是一般過去時態時，從句只能使用過去范圍內的任何時態。但客觀真理除外。如：
The teacher said that the earth goes round the sun.
老師說地球繞著太陽運行。
四、同位語從句
1. 定義：用作同位語的從句叫做同位語從句。
2. 用法：同位語從句的先行詞多為fact, news, idea, thought, question, reply, report, remark等，關聯詞多用從屬連詞that。如：
They were all very much worried over the fact that you were sick.
對你生病這件事，他們都很焦慮。
Where did you get the idea that I could not come?
你在哪兒聽說我不能來?
Early in the day came the news that Germany had declared war on Russia.
德國已對俄國宣戰的消息一大早就傳來了。
注：同位語從句偶爾由從屬連詞whether引導。如：
I have no idea whether he’ll come or not. 我不知道他是否來。
連接代詞who, which, what和連接副詞where, when, why, how亦可引導同位語從句。
The question who should do the work requires consideration.
誰該干這項工作，這個問題需要考慮。
We haven't yet settled the question where we are going to spend our summer vacation.
到哪兒去度暑假，這個問題我們還沒有決定。
It is a question how he did it.

(6)不定式的構成
1. 不定式的構成
不定式是由不定式符號to+動詞原形構成，在某些情況下to也可省略。
不定式一般有時式和語態的變化，通常有下表中的幾種形式(以do為例)：
主動式
被動式
一般式
to do
to be done
完成式
to have done
to have been done
進行式
to be doing
/
完成進行式
to have been doing
/
1) 不定式的一般式
不定式的一般式所表示的動作通常與主要謂語的動作同時或幾乎同時發生，或是在它之后發生。如：
They invited us to go there this summer. 他們邀請我們今年夏天去那兒。
He stood aside for me to pass. 他站到一邊讓我通過。
2) 不定式的完成式
不定式的完成式所表示的動作在謂語所表示的動作之后發生，它在句中可作表語、狀語、賓語，有時也可作主語、定語等。如：
She seemed to have heard about this matter. 她似乎已聽說過這件事。
I am sorry to have kept you waiting so long. 我很抱歉讓你等了這么久。
I meant to have told you about it, but I happened to have an important thing to do.

It has been an honor for me to have traveled so much in your country.
對我來說，在你們國家旅行這么多地方是一件很榮幸的事情。
3) 不定式的進行式
不定式的進行式表示正在進行的與謂語動詞同時發生的動作。它在句中可以用作除謂語以外的所有成分。如：
It’s nice of you to be helping us these days. 你真好，這些天一直幫我們。
He pretended to be listening to the teacher carefully. 他假裝在認真地聽老師講課。
We didn’t expect you to be waiting for us here. 我們沒料到你一直在這兒等我們。
4) 不定式的完成進行式
如果不定式表示的動作是謂語所表示時間之前一直進行的動作，就需要用完成進行式。如：
They are said to have been working in Tibet for 20 years. 據說他們已經在西藏工作20年了。
We are happy to have been helping each other these days. 我們很高興這些天能互相幫助。
5) 動詞不定式的否定形式是由not或never加不定式構成。如：
Try not to be late again next time. 盡量下次不要再遲到。
He wished us never to meet her again. 他希望我們永遠不要再見到她。
6) 疑問詞+動詞不定式：
不定式和疑問詞whether, what, which, whom, where, when, how, why等連用可以在句中起名詞的作用，通常跟在tell, know, show, decide, learn, wonder, explain, advise, teach, discuss, find out等動詞后面作賓語，有時也可以充當主語、表語等。如：
On hearing the news, he didn't know whether to laugh or to cry.
聽到這個消息，他不知道該哭還是該笑。
When to hold the meeting has not decided. 什么時候開會還沒有決定。
The most important problem is how to get so much money.

I have no idea of how to do it. 我不知道該怎么做。
(7)-ing分詞的構成
1. -ing分詞的構成
-ing分詞是由動詞原形加詞尾-ing構成。-ing分詞同樣有時態和語態的變化，通常有下表幾種形式(以do為例)：
主動形式
被動形式
一般式
doing
being done
完成式
having done
having been done
-ing分詞的否定形式是由not 加-ing分詞構成。如：
Not knowing his address, I could do nothing but stay at home and wait.
不知道他的地址，我只好在家里等著。
His not coming made all of us angry. 他沒來使我們大家都很生氣。
2. -ing分詞的一般式和完成式：
-ing分詞的一般式表示和謂語動詞所表示的動作同時進行的動作;完成式表示在謂語動詞所表示的動作之前發生的動作。如：
Being a student, he was interested in books. 作為一個學生，他對書本很感興趣。
Not having studied his lessons very hard, he failed the examinations. 因為沒有努力學習功課，他考試不及格。
3. -ing分詞的被動式：
-ing分詞的被動式表示它的邏輯主語是-ing分詞動作的承受者。根據-ing分詞動作發生的時間，-ing分詞的被動式有一般被動式(being done)和完成被動式(having been done)。如：
The question being discussed is very important. 正在被討論的問題很重要。
He never talked about his having been interviewed by the reporter. 他從來沒談起過他被記者采訪的事情。
Having been criticized by the teacher, he gave up smoking. 被老師批評以后，他把煙戒了。
注意：在need, want, require, be worth等動詞(短語)后，作賓語的-ing分詞常用主動形式來表示被動含義。如：
Your shoes need cleaning. = Your shoes need to be cleaned. 你的鞋需要清洗一下了。
This book is well worth reading. 這本書很值得一看。
4. -ing分詞的語法作用
-ing分詞一方面具有動詞的性質，另一方面也相當于一個名詞或形容詞、副詞，在句中可以作主語、表語、賓語、定語、狀語和補語等。
1)–ing分詞(短語)作主語：
Laying eggs is the ant queen''s full-time job. 產卵是蟻后的專職工作。
Saying is easier than doing. 說比做容易。

It is no use crying over spilt milk. 作無益的后悔是沒有用的。
It''s a waste of time arguing about it. 辯論這事是浪費時間。
②在There is no結構中，通常用-ing分詞。如：

They don’t feel like walking that much. 他們不喜歡走那么多路。

此類短語還有很多。如：look forward to(渴望，盼望), be proud of(以……自豪), be responsible for(對……負責), insist on(堅持), think of(考慮，想到), dream of(夢想), object to(反對，抗議), hear of(聽說), prevent…from(防止，阻止), keep…from(防止，阻止), stop…from(防止，阻止), be engaged in(從事于), depend on(依*，依賴), thank…for(因……而道謝), excuse…for(因……而道歉), aim at(目的在于), devote…to(獻身于), set about(著手做), be/get used to(習慣于), be fond of(喜歡), be afraid of(害怕), be tired of(對……厭煩), succeed in(成功地做……), be interested in(對……感興趣), be ashamed of(對……感到羞愧)等等。

He left ahead of time without saying a word. 他一句話也沒說就提前離開了。
Besides cooking and sewing, she had to take care of four children.
除了做飯和縫紉以外，她還要照顧四個孩子。
On hearing the news, all the pupils jumped with joy. 聽到這個消息后，所有的學生都高興得跳了起來。
4) -ing分詞作定語：
①單個的分詞作定語一般放在被修飾詞的前面。如：
reading room 閱覽室 swimming pool 游泳池 dining car 餐車
sleeping car 臥車 singing competition 歌詠比賽 waiting room 候車室

③–ing分詞還可以作非限制性定語，相當于一個非限制性定語從句，常用逗號和句子其它部分分開。如:

一個人如站在大山的腳下會發現自己很渺小。

注：-ing分詞作狀語時，它的邏輯主語就是整個句子的主語。
⑥“with/without+名詞普通格或代詞賓格+-ing分詞”結構在句中作狀語，表示伴隨情況或時間、原因等。如：
His hair became grey with the years passing. 隨著時間的推移，他的頭發變花白了。
Without anyone noticing, he slipped through the window. 沒人注意，他從窗戶溜了出去。
6) -ing分詞作補語：
①--ing分詞可以在see, hear, notice, watch, feel, look at, listen to, observe, have, get, leave, keep, set, catch, find等動詞后面和一個名詞或代詞構成一個復合賓語，作賓語補語。如：
I noticed a man running out of the bank when I got off the car.
我下車的時候注意到一個男人匆匆忙忙地從銀行里跑出來。
Last night the shopkeeper caught a child stealing some food in the shop.
昨晚，店主在商店里抓到一個小孩在偷東西。
②上面這類句子也可變成被動語態，這時，-ing分詞可看成是主語補語。如：

Jily was never heard singing that song again. 人們再也沒有聽到吉麗唱這首歌了。
5. -ing分詞的復合結構：

He was awakened by someone’s knocking at the door. 他被某人的敲門聲吵醒了。
1. –ing分詞作主語和表語時與不定式的區別：
-ing分詞和動詞不定式作主語和表語的主要區別在于：在表示比較抽象的一般的多次性行為時多用-ing分詞;在表示具體的或一次性的動作，特別是將來的動作時，多用不定式。如：
Smoking is forbidden here. (泛指吸煙)這里禁止吸煙。
It’s not good for you to smoke so much. (指你吸煙)吸這么多煙對你的身體不好。
My job is teaching. 我的工作是教書。
My job is to teach you English this term. 我這一學期的工作是教你們英語。
2. 高中階段能接-ing分詞作賓語的常見動詞：
mind(介意), suggest(建議), enjoy(欣賞，), admit(承認), appreciate(感激，欣賞), avoid(避免), delay(推遲), dislike(不喜歡，厭惡), escape(逃脫), finish(完成), forgive(寬恕), imagine(想象), keep(保持), miss(錯過), practise(訓練), resist(抵抗，抵制), risk(冒險), deny(拒絕，否認), consider(考慮)等。
3. 有些動詞既能接不定式，又能接-ing分詞，含義有所不同。如：
①forget, remember, regret等詞后面接不定式表示不定式動作后于謂語動作，而后接-ing分詞作賓語表示分詞動作先于謂語動作。如：
Do you remember seeing me before? 你記得以前見過我嗎?
Remember to lock the door when you leave. 離開時要記得鎖門。
②動詞mean, stop, try, go on等動詞后面接分詞和接不定式作賓語，意思也有所不同。如：
I try not to think about that. 我盡量不去想那件事。
Would you please try doing that again? 請你再試一次好嗎?
I mean to change it for another one. 我想換成另外一個。
Missing the train means waiting for another hour. 誤了這班車就意味著再等一個小時。
Having finished the exercises, we went on to learn the new words in the next unit.
做完練習以后，我們繼續學習下一單元的單詞。
After a short rest, they went on working. 短暫地休息以后，他們又繼續工作。
He stopped talking when the bell rang. 鈴響的時候，他停止了講話。
While working, he stopped to talk with Tom at times. 工作的時候，他不時地停下來和湯姆談話。
注意：有時人們把stop后的動詞不定式理解為目的狀語。
③動詞allow, advise, forbid, permit等可直接跟-ing分詞作賓語，不可以接動詞不定式作賓語，但可接不定式作賓語補語。如：
Please permit me to say a few words. 請允許我說幾句話。
We don’t permit smoking here. 我們這兒不允許吸煙。
④動詞need, require, want作“需要”解時，后面接-ing分詞或不定式的被動式。如：
The room wants cleaning/to be cleaned. 這個房間需要打掃。
These little children require looking after carefully/to be looked after carefully.
這些小孩需要細心地照料。
⑤動詞like, hate, prefer等后面，如表示一般性動作，多用-ing分詞;如指特定的具體的某次動作，多用不定式。如：
I like swimming, but I don’t like to swim with you. 我喜歡游泳，但我不喜歡和你一起游泳。
I prefer walking to school every day. 我情愿每天步行去學校。
I prefer to stay at home today. 今天我情愿呆在家里。
⑥動詞begin, start后面，如表示有意識地開始做某事，常用-ing分詞，否則用不定式更多一些。如：
We began to do that job last year. 我們去年開始做那工作的。
They started talking about the film at once. 他們立刻開始談論那部電影。
注：下面幾種情況多用不定式作賓語：
a. 當start, begin本身用于進行時態時。
When the teacher came into the room, he was starting to write to his parents.
老師走進教室的時候，他正開始寫信給他的父母親。
b. 當start, begin后接表示心理活動的動詞時。
Hearing the news, he started to think of a good way to solve the problem.
一聽到消息，他就開始考慮一個好辦法來解決這個問題。
c. 當句子的主語是無生命的東西時。
We were about to leave when it began to rain. 我們正準備離開，天開始下雨了。
4. -ing分詞作表語的兩種不同含義：
①-ing分詞作表語可以表示主語的內容是什么。如：
Their job is building houses. 他們的工作是蓋房子。
The real question is getting to know the needs of the people. 真正的問題是了解人民的需要。
②-ing分詞作表語還可以表示主語所具有的特征。如：
This story is very interesting. 這故事很有趣。
The problem is quite puzzling. 這個問題很令人困惑。
①–ing分詞作定語可用來說明被修飾的名詞的用途和性能。如：
reading material 閱讀材料 walking stick 手杖 fishing pole 魚桿
flying suit 飛行服 writing table 寫字臺 listening practice 聽力訓練
②-ing分詞作定語還可以表示所修飾的人或物的動作或狀態，在意思上接近一個定語從句，可以表示正在進行的動作，也可表示經常性動作或當時的狀態。如：
developing countries = countries that are developing 發展中國家
a growing city = a city that is growing 發展著的城市
an ordinary-looking house = a house that looks ordinary 看起來很普通的房子
a touching story = a story that is touching 一個動人的故事
working people= people who are working 勞動人民
6. 不定式和-ing分詞作賓語補語的區別：
在see, hear, feel, watch, notice等感官動詞后，既可用-ing分詞構成復合賓語，也可用不定式構成復合賓語，兩者之間有一定的區別。用-ing分詞時，表示動作正在進行;用不定式時，表示動作發生了，即動作的全過程結束了。如：
Do you hear someone knocking at the door? (Someone is knocking at the door.) 有人在敲門你聽見了嗎?
Do you hear someone knock at the door? (Someone knocked at the door just now.) 你聽見有人敲門了嗎?
7. 高中階段常見的帶介詞to的短語，后接-ing分詞或名詞。如：
admit to(承認), contribute to(捐助、貢獻), get down to(著手做), give way to(讓位于)，keep to (堅持、遵守), lead to (導致),look forward to(期待), take to(從事), turn to (求助于), stick to(忠于、堅持), point to(指向、表明), see to (注意、處理), be used to (習慣于), devote oneself to (獻身于), be equal to (勝任的、等于), be familiar to (為……熟悉).
高中階段有一些固定的-ing分詞短語，如generally speaking(一般來說), judging from…(根據……來判斷), considering…(考慮到……), talking of…(談到……，提到……), supposing…(假如……)等，它們的邏輯主語和句子的主語不一致。這種短語可以被稱之為句子的狀語，也可當作一個插入語。如：
Judging from his accent, he must come from Canada. 從他的口音看他一定來自加拿大。
Considering how poor he was, we decided to let him attend the concert for free.
考慮到他是多么的窮，我們決定讓他免費聽音樂會。
