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正常为系动词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. 毫无疑难她测验成就会很好.
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:
Itrs a pity that we canrt go. 很遗憾我们不能去.
Itrs no surprise that our team should have won the game. 我们没赢这场竞赛真意外.
C. It+be+过去分词(said, reported, thought, expected, decided, announced, arranged, etc.)+that从句.如:

It doesnrt 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差别.
F. 当that引导的主语从句呈现在疑问句中时,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? 下周那位迷信家将给我们作讲演是真的吗?
Does it matter much that they will not come tomorrow? 他们来日不来很要紧吗?
G. 当主语从句涌现在感慨句中时,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! 孩子们这么宁静真奇怪!
2.注意连接代词whoever, whatever, whichever等引导主语从句的含意
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) 他所做的事情是准确的.
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. 他对咱们说他觉得不舒畅.
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件并知道Tom十分惧怕.
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.)
对他我一窍不通,只知道他是南方人.
3.That he ever said such a thing I simply donrt believe. (that从句位于句首时,that不可省略.)
我几乎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.)
鉴于他的特别情形,我们决议应允他一段试用期.
(2)从属连词if/whether.如:
I doubt whether he will succeed. 我猜忌他是否会成功.
I donrt know if you can help me. 我不知道你是否辅助我.
(3)连接代词who, whom, whose, what, which, whoever, whatever, whichever
连接副词 where, when, how, why.

他是什么人?他是干什么的?马丁基本不知道.
I wonder what hers writing to me about. 我不知道他要给我写信说什么事.
Irll tell you why I asked you to come. 我会告知你我为什么要你来.

(1) 介词宾语从句
宾语从句也可用作介词的宾语.如:

他对那天产生的事感到很不快.
I walked over to where she sat. 我走向她坐的处所.
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.
你是否成功将重要取决于你做什么和怎么做.
有时介词可以省略.如:
I donrt care (for) who marries him. 我不论谁跟他结婚.
Be careful (as to) how you do that. 你要留神做这件事的方法.
解释:
1.假如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.
我们以为小王昨天没来是奇异的.
He has made it clear that he will not give in.
他已表明他不会屈从.
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.其余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,只是有点大意.
You may rely on it that I shall help you. 你可以指望我会赞助你的.
介词宾语不能够用which来引导,而要用what来引诱.如:
Are you sorry for what you've done?
你为你所做的所有感到内疚吗?
3.某些形容词或从前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.
我不能断定我该做什么.
I'm afraid you don't understand what I said.
恐怕你没懂得我说的意思.
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愉快.
4.连词whether (hor not)或if引导的宾语从句
if和whether引导的宾语从句可以调换使用,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,应防止使用if而用wheter.试比拟:
Please let me know if you want to go.
Please let me know whether you want to go.
if从句可懂得为宾语从句,意为"请告诉我你是否想去";此句又可理解为前提状语从句意为"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,有时谓语只管是否定意思,却不用否定形式,而将think等动词变为否认情势.如:
I donrt think you are right. 我认为你错了.
I donrt believe they have finished their work yet. 我信任他们还未实现他们的工作.
I donrt suppose he cares, does he? 我想他不在意,是吗?
6. 宾语从句的时态变更法则:
(1) 当主句是普通当初时态时,从句可依据须要用任何时态.
(2) 当主句是一般过去时态时,从句只能应用过去范畴内的任何时态.但客观真谛除外.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,他们都很焦急.
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:同位语从句偶然由从属连词whether引导.如:
I have no idea whether herll come or not. 我不晓得他是否来.
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,这个问题我们还不决定.
It is a question how he did it.
那是一个他如何做了此事的问题.
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
句法功效上
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替换先行词在从句中不仅起连接作用,还充任一个句子成分.如在从句中作动词的宾语时可省略.
意思上
从句是被润饰名词的内容.
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,18 最多半小时我就饿逝世了,that在从句中作told的宾语,可省.)
他昨天告诉我的消息是真的.
2.一些表现"倡议、命令、请求"的名词后所跟的同位语从句中,谓语动词用虚构语气should+动词本相表示.should可省.如:
This is our only request that this (should) be settled as soon as possible.
这就是我们独一的恳求:尽快解决这个问题.
