这都是20多年前的事了，但宛如昨天一样。
能跟表语从句的谓语动词一般为系动词be, seem, look等。如：

解释：
1． 主语从句能用it作形式上的主语。常以it作形式主语的句型有：
A. It+be+形容词(obvious, true, natural, surprising, good, wonderful, funny, possible, likely, certain, probable, etc.)+that从句。如：
It is certain that she will do well in her exam. 毫无疑问她考试成绩会很好。
It is probable that he told her everything. 很可能他把一切都告诉她了。
B. It+be+名词词组(no wonder, an honour, a good thing, a pity, no surprise, etc.)+that从句。如：
It’s a pity that we can’t go. 很遗憾我们不能去。
It’s no surprise that our team should have won the game. 我们没赢这场比赛真意外。
C. It+be+过去分词(said, reported, thought, expected, decided, announced, arranged, etc.)+that从句。如：

E. It+doesn’t matter (makes no difference, etc.)+连接代词或连接副词引起的主语从句。如：
It doesn’t matter whether she will come or not. 她是否来这无关紧要。
It makes no difference where we shall have the meeting. 我们在哪里开会毫无区别。
F. 当that引导的主语从句出现在疑问句中时，要以it作形式主语，而把主语从句后置。如：
Is it true that the scientist will give us a lecture next week? 下周那位科学家将给我们作报告是真的吗？
Does it matter much that they will not come tomorrow? 他们明天不来很要紧吗？
G. 当主语从句出现在感叹句中时，要以it作形式主语，而把主语从句后置。如：
How strange it is that the children are so quiet! 孩子们这么安静真奇怪！
2．注意连接代词whoever, whatever, whichever等引导主语从句的含义
Whoever comes will be welcome. (whoever=the person who) 来的人将受到欢迎。
Whatever he did was right. (whatever=the thing that) 他所做的事情是正确的。
Whichever of you comes in will receive a prize. (whichever=anyone of you who) 你们当中不论哪个进来将会得到奖
（3）宾语从句
1． 定义：用作宾语的从句叫宾语从句。
2． 构成：关联词+简单句
3． 引导宾语从句的关联词有三类：
(1) 从属连词that。如：
He told us that he felt ill. 他对我们说他感到不舒服。
I know he has returned. 我知道他已经回来了。
注： that在引导宾语从句时也并不是任何情况下都可以省略。在以下情况下，that不能省略。
1． Everybody could see what happened and that Tom was frightened.(and连接两个宾语从句，that宾语从句放在and的后面时，that不能省略。)
大家都会看出所发生的事情并知道Tom非常害怕。
2．I know nothing about him except that he is from the south.(that引导的宾语从句作介词宾语时，that不能省略。)
对他我一无所知，只知道他是南方人。
3．That he ever said such a thing I simply don’t believe. (that从句位于句首时，that不可省略。)
我简直不相信他曾说过这样的话。
4． We decided, in view of his special circumstances, that we would admit him for a probationary period. (主句谓语动词与that从句之间有插入语，that不可省略。)
鉴于他的特殊情况，我们决定应允他一段试用期。
(2)从属连词if/whether。如：
I doubt whether he will succeed. 我怀疑他是否会成功。
I don’t know if you can help me. 我不知道你能否帮助我。
(3)连接代词who, whom, whose, what, which, whoever, whatever, whichever
连接副词 where, when, how, why。
如：
Who or what he was, Martin never learned.
他是什么人？他是干什么的？马丁根本不知道。
I wonder what he’s writing to me about. 我不知道他要给我写信说什么事。
I’ll tell you why I asked you to come. 我会告诉你我为什么要你来。
You may do what you will. 你可做任何你想做的事。
(1) 介词宾语从句
宾语从句也可用作介词的宾语。如：
He was deeply displeased by what had occurred that day.
他对那天发生的事感到很不快。
I walked over to where she sat. 我走向她坐的地方。
I am curious as to what he will say. 我很想知道他要说什么。
Your success will largely depend upon what you do and how you do it.
你是否成功将主要取决于你做什么和怎样做。
有时介词可以省略。如：
I don’t care (for) who marries him. 我不管谁跟他结婚。
Be careful (as to) how you do that. 你要注意做这件事的方式。
解释：
1．如果宾语从句后还有宾语补足语，则用it作形式宾语，而将宾语从句后置。如：
We thought it strange that Xiao Wang did not come yesterday.
我们认为小王昨天没来是奇怪的。
He has made it clear that he will not give in.
他已表明他不会屈服。
2．作介词的宾语：连词that引导的名词性从句很少作介词的宾语，只用在except, but, in后。其他一些介词的宾语从句如果由连词that引导，则需用it先行一步，作形式宾语。如：
He is a good student except that he is careless.
他是一个好学生，只是有点粗心。
You may rely on it that I shall help you. 你可以指望我会帮助你的。
介词宾语不可以用which来引导，而要用what来引导。如：
Are you sorry for what you've done?
你为你所做的一切感到内疚吗？
3．某些形容词或过去分词后常接宾语从句，这类形容词或过去分词有sure, glad, certain, pleased, happy, afraid, surprised, satisfied等，连词that可省略。如：
I am not sure what I ought to do.
我不能确定我该做什么。
I'm afraid you don't understand what I said.
恐怕你没领会我说的意思。
I'm surprised that I didn't see all that before.
我好奇怪，我以前没看到过。
Mother was very pleased her daughter had passed the exams.
妈妈为她的女儿通过了考试而感到高兴。
4．连词whether (…or not)或if引导的宾语从句
if和whether引导的宾语从句可以互换使用，但whether常和or not连用，if一般不与or not连用。如：
I wonder whether it is true or not. 我不知它是真是假。
用if引导宾语从句如果会引起歧义，应避免使用if而用wheter。试比较：
Please let me know if you want to go.
Please let me know whether you want to go.
if从句可理解为宾语从句，意为“请告诉我你是否想去”；此句又可理解为条件状语从句意为“如果你想去的话，请告诉我一声”。
5．宾语从句的否定转移。在think, believe, suppose, expect等动词后的宾语从句，有时谓语尽管是否定意思，却不用否定形式，而将think等动词变为否定形式。如：
I don’t think you are right. 我认为你错了。
I don’t believe they have finished their work yet. 我相信他们还未完成他们的工作。
I don’t suppose he cares, does he? 我想他不在意，是吗？
6． 宾语从句的时态变化规律：
(1) 当主句是一般现在时态时，从句可根据需要用任何时态。
(2) 当主句是一般过去时态时，从句只能使用过去范围内的任何时态。但客观真理除外。如：
The teacher said that the earth goes round the sun.
老师说地球绕着太阳运行。
（4）同位语从句
1． 定义：用作同位语的从句叫做同位语从句。
2． 用法：同位语从句的先行词多为fact, news, idea, thought, question, reply, report, remark等，关联词多用从属连词that。如：
They were all very much worried over the fact that you were sick.
对你生病这件事，他们都很焦虑。
Where did you get the idea that I could not come?
你在哪儿听说我不能来？
Early in the day came the news that Germany had declared war on Russia.
德国已对俄国宣战的消息一大早就传来了。
注：同位语从句偶尔由从属连词whether引导。如：
I have no idea whether he’ll come or not. 我不知道他是否来。
连接代词who, which, what和连接副词where, when, why, how亦可引导同位语从句。
The question who should do the work requires consideration.
谁该干这项工作，这个问题需要考虑。
We haven't yet settled the question where we are going to spend our summer vacation.
到哪儿去度暑假，这个问题我们还没有决定。

解释：
1．that引导的同位语从句与定语从句之区别
that引导的同位语从句
that引导的定语从句
句法功能上
that只起连接从句的作用，无意义。在从句中不充当句子成分。不可省。
that替代先行词在从句中不仅起连接作用，还充当一个句子成分。如在从句中作动词的宾语时可省略。
意义上
从句是被修饰名词的内容。
从句起限定作用，是定语
如：The news that Mr. Li will be our new English teacher is true. (同位语从句，that不可省。)
李先生将是我们的新英语老师这个消息是真的。
The news (that) he told me yesterday is true. (定语从句，that在从句中作told的宾语，可省。)
他昨天告诉我的消息是真的。
2．一些表示“建议、命令、要求”的名词后所跟的同位语从句中，谓语动词用虚拟语气should+动词原形表示。should可省。如：

(6）不定式的构成
1. 不定式的构成
不定式是由不定式符号to+动词原形构成，在某些情况下to也可省略。
不定式一般有时式和语态的变化，通常有下表中的几种形式（以do为例）：
主动式
被动式
一般式
to do
to be done
完成式
to have done
to have been done
进行式
to be doing
/
完成进行式
to have been doing
/
1) 不定式的一般式
不定式的一般式所表示的动作通常与主要谓语的动作同时或几乎同时发生，或是在它之后发生。如：
They invited us to go there this summer. 他们邀请我们今年夏天去那儿。
He stood aside for me to pass. 他站到一边让我通过。
2) 不定式的完成式
不定式的完成式所表示的动作在谓语所表示的动作之后发生，它在句中可作表语、状语、宾语，有时也可作主语、定语等。如：
She seemed to have heard about this matter. 她似乎已听说过这件事。
I am sorry to have kept you waiting so long. 我很抱歉让你等了这么久。
I meant to have told you about it, but I happened to have an important thing to do.
我本来想告诉你这件事的，但我碰巧有一件重要的事要做。
It has been an honor for me to have traveled so much in your country.
对我来说，在你们国家旅行这么多地方是一件很荣幸的事情。
3) 不定式的进行式
不定式的进行式表示正在进行的与谓语动词同时发生的动作。它在句中可以用作除谓语以外的所有成分。如：
It’s nice of you to be helping us these days. 你真好，这些天一直帮我们。
He pretended to be listening to the teacher carefully. 他假装在认真地听老师讲课。
We didn’t expect you to be waiting for us here. 我们没料到你一直在这儿等我们。
4) 不定式的完成进行式
如果不定式表示的动作是谓语所表示时间之前一直进行的动作，就需要用完成进行式。如：
They are said to have been working in Tibet for 20 years. 据说他们已经在西藏工作20年了。
We are happy to have been helping each other these days. 我们很高兴这些天能互相帮助。
5) 动词不定式的否定形式是由not或never加不定式构成。如：
Try not to be late again next time. 尽量下次不要再迟到。
He wished us never to meet her again. 他希望我们永远不要再见到她。
6) 疑问词+动词不定式：
不定式和疑问词whether, what, which, whom, where, when, how, why等连用可以在句中起名词的作用，通常跟在tell, know, show, decide, learn, wonder, explain, advise, teach, discuss, find out等动词后面作宾语，有时也可以充当主语、表语等。如：
On hearing the news, he didn't know whether to laugh or to cry.
听到这个消息，他不知道该哭还是该笑。
When to hold the meeting has not decided. 什么时候开会还没有决定。
The most important problem is how to get so much money.
最重要的事情是如何搞到这么多钱。
介词后一般不直接接不定式，但可以接疑问词+不定式短语作宾语。如：
Mary gave some advice on how to learn English. 玛丽提了一些如何学习英语的建议。
I have no idea of how to do it. 我不知道该怎么做。
（7）-ing分词的构成
1. -ing分词的构成
-ing分词是由动词原形加词尾-ing构成。-ing分词同样有时态和语态的变化，通常有下表几种形式（以do为例）：
主动形式
被动形式
一般式
doing
being done
完成式
having done
having been done
-ing分词的否定形式是由not 加-ing分词构成。如：
Not knowing his address, I could do nothing but stay at home and wait.
不知道他的地址，我只好在家里等着。
His not coming made all of us angry. 他没来使我们大家都很生气。
2. -ing分词的一般式和完成式：
-ing分词的一般式表示和谓语动词所表示的动作同时进行的动作；完成式表示在谓语动词所表示的动作之前发生的动作。如：
Being a student, he was interested in books. 作为一个学生，他对书本很感兴趣。
Not having studied his lessons very hard, he failed the examinations. 因为没有努力学习功课，他考试不及格。
3. -ing分词的被动式：
-ing分词的被动式表示它的逻辑主语是-ing分词动作的承受者。根据-ing分词动作发生的时间，-ing分词的被动式有一般被动式(being done)和完成被动式(having been done)。如：
The question being discussed is very important. 正在被讨论的问题很重要。
He never talked about his having been interviewed by the reporter. 他从来没谈起过他被记者采访的事情。
Having been criticized by the teacher, he gave up smoking. 被老师批评以后，他把烟戒了。
注意：在need, want, require, be worth等动词(短语)后，作宾语的-ing分词常用主动形式来表示被动含义。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. 这本书很值得一看。
4. -ing分词的语法作用
-ing分词一方面具有动词的性质，另一方面也相当于一个名词或形容词、副词，在句中可以作主语、表语、宾语、定语、状语和补语等。
1)–ing分词（短语）作主语：
Laying eggs is the ant queen''s full-time job. 产卵是蚁后的专职工作。
Saying is easier than doing. 说比做容易。
在下面两种结构中，-ing分词也作主语。

It is no use crying over spilt milk. 作无益的后悔是没有用的。
It''s a waste of time arguing about it. 辩论这事是浪费时间。
②在There is no结构中，通常用-ing分词。如：
There is no joking about such matters. 这种事开不得玩笑。

2) -ing分词（短语）作表语：

①–ing分词作动词宾语。如：I suggest doing it in a different way. 我建议用另一种方法做这件事。

He left ahead of time without saying a word. 他一句话也没说就提前离开了。
Besides cooking and sewing, she had to take care of four children.
除了做饭和缝纫以外，她还要照顾四个孩子。
On hearing the news, all the pupils jumped with joy. 听到这个消息后，所有的学生都高兴得跳了起来。
4) -ing分词作定语：
①单个的分词作定语一般放在被修饰词的前面。如：
reading room 阅览室 swimming pool 游泳池 dining car 餐车
sleeping car 卧车 singing competition 歌咏比赛 waiting room 候车室
a waiting car 一辆等待着的车 a sleeping child一个酣睡的孩子 flying fish 飞鱼
the exciting news令人振奋的消息 a boring speech令人乏味的演出

Who is the comrade standing by the door? 站在门边的同志是谁？
They lived in a house facing south. 他们住在一所朝南的房子里。
③–ing分词还可以作非限制性定语，相当于一个非限制性定语从句，常用逗号和句子其它部分分开。如:

歌词一般讲当前的工作，大部分是他自己写的。
When she appeared, John, wearing a dirty and worn-out overcoat, ran to her with joy. 当她出现的时候，约翰穿着一件又脏又破的大衣高兴地跑了过去。
5) -ing分词做状语：
-ing分词作状语可以表示时间、原因、结果、条件、让步、方式或伴随情况等。

注：-ing分词作状语时，它的逻辑主语就是整个句子的主语。
⑥“with/without+名词普通格或代词宾格+-ing分词”结构在句中作状语，表示伴随情况或时间、原因等。如：

6) -ing分词作补语：
①--ing分词可以在see, hear, notice, watch, feel, look at, listen to, observe, have, get, leave, keep, set, catch, find等动词后面和一个名词或代词构成一个复合宾语，作宾语补语。如：

5. -ing分词的复合结构：

1. –ing分词作主语和表语时与不定式的区别：
-ing分词和动词不定式作主语和表语的主要区别在于：在表示比较抽象的一般的多次性行为时多用-ing分词；在表示具体的或一次性的动作，特别是将来的动作时，多用不定式。如：
Smoking is forbidden here. （泛指吸烟）这里禁止吸烟。
It’s not good for you to smoke so much. （指你吸烟）吸这么多烟对你的身体不好。
My job is teaching. 我的工作是教书。

2. 高中阶段能接-ing分词作宾语的常见动词：

3. 有些动词既能接不定式，又能接-ing分词，含义有所不同。如：
①forget, remember, regret等词后面接不定式表示不定式动作后于谓语动作，而后接-ing分词作宾语表示分词动作先于谓语动作。如：
Do you remember seeing me before? 你记得以前见过我吗？
Remember to lock the door when you leave. 离开时要记得锁门。
②动词mean, stop, try, go on等动词后面接分词和接不定式作宾语，意思也有所不同。如：

Would you please try doing that again? 请你再试一次好吗？
I mean to change it for another one. 我想换成另外一个。
Missing the train means waiting for another hour. 误了这班车就意味着再等一个小时。

注意：有时人们把stop后的动词不定式理解为目的状语。
③动词allow, advise, forbid, permit等可直接跟-ing分词作宾语，不可以接动词不定式作宾语，但可接不定式作宾语补语。如：
Please permit me to say a few words. 请允许我说几句话。
We don’t permit smoking here. 我们这儿不允许吸烟。
④动词need, require, want作“需要”解时，后面接-ing分词或不定式的被动式。如：

These little children require looking after carefully/to be looked after carefully.
这些小孩需要细心地照料。
⑤动词like, hate, prefer等后面，如表示一般性动作，多用-ing分词；如指特定的具体的某次动作，多用不定式。如：
I like swimming, but I don’t like to swim with you. 我喜欢游泳，但我不喜欢和你一起游泳。
I prefer walking to school every day. 我情愿每天步行去学校。
I prefer to stay at home today. 今天我情愿呆在家里。
⑥动词begin, start后面，如表示有意识地开始做某事，常用-ing分词，否则用不定式更多一些。如：
We began to do that job last year. 我们去年开始做那工作的。
They started talking about the film at once. 他们立刻开始谈论那部电影。
注：下面几种情况多用不定式作宾语：
a. 当start, begin本身用于进行时态时。

b. 当start, begin后接表示心理活动的动词时。

4. -ing分词作表语的两种不同含义：
①-ing分词作表语可以表示主语的内容是什么。如：
Their job is building houses. 他们的工作是盖房子。
The real question is getting to know the needs of the people. 真正的问题是了解人民的需要。
②-ing分词作表语还可以表示主语所具有的特征。如：
This story is very interesting. 这故事很有趣。
The problem is quite puzzling. 这个问题很令人困惑。
①–ing分词作定语可用来说明被修饰的名词的用途和性能。如：
reading material 阅读材料 walking stick 手杖 fishing pole 鱼杆
flying suit 飞行服 writing table 写字台 listening practice 听力训练
②-ing分词作定语还可以表示所修饰的人或物的动作或状态，在意思上接近一个定语从句，可以表示正在进行的动作，也可表示经常性动作或当时的状态。如：
developing countries = countries that are developing 发展中国家
a growing city = a city that is growing 发展着的城市
an ordinary-looking house = a house that looks ordinary 看起来很普通的房子
a touching story = a story that is touching 一个动人的故事
working people= people who are working 劳动人民
6. 不定式和-ing分词作宾语补语的区别：
在see, hear, feel, watch, notice等感官动词后，既可用-ing分词构成复合宾语，也可用不定式构成复合宾语，两者之间有一定的区别。用-ing分词时，表示动作正在进行；用不定式时，表示动作发生了，即动作的全过程结束了。如：
Do you hear someone knocking at the door? (Someone is knocking at the door.) 有人在敲门你听见了吗？
Do you hear someone knock at the door? (Someone knocked at the door just now.) 你听见有人敲门了吗？
7. 高中阶段常见的带介词to的短语，后接-ing分词或名词。如：
admit to（承认）, contribute to（捐助、贡献）, get down to（着手做）, give way to（让位于），keep to （坚持、遵守）, lead to （导致）,look forward to（期待）, take to（从事）, turn to （求助于）, stick to（忠于、坚持）, point to（指向、表明）, see to （注意、处理）, be used to （习惯于）, devote oneself to （献身于）, be equal to （胜任的、等于）, be familiar to （为……熟悉）.
高中阶段有一些固定的-ing分词短语，如generally speaking（一般来说）, judging from…（根据……来判断）, considering…（考虑到……）, talking of…（谈到……，提到……）, supposing…（假如……）等，它们的逻辑主语和句子的主语不一致。这种短语可以被称之为句子的状语，也可当作一个插入语。如：
Judging from his accent, he must come from Canada. 从他的口音看他一定来自加拿大。
Considering how poor he was, we decided to let him attend the concert for free.
考虑到他是多么的穷，我们决定让他免费听音乐会。
