二、名词性从句

1. 主语从句:是在复合句中充当主语的从句,常放在主句谓语动词之前或由形式主语it代替,而本身放在句子末尾。

Eg:   That the earth turns around the sun is known to all.

      It doesn’t interest me whether you succeed or not.

(1)提示:①连词that引导主语从句放在句首时,无词义,不作句子成分,但不能省略。

      ②if引导的主语从句不能放在句首,而whether引导的主语从句既可放在句首也可放句尾。

Eg:If he will succeed is not sure . (x)

    Whether it is true remains a question. (√)

(2)连接代词who, whom, whose, what, which有词义,在从句中担任成分,如主语、表语、宾语或定语;

(3)连接副词when, where, why, how有词义,在从句中担任状语。

Eg:  ________ we need is more pratice.    我们所需要的是更多的训练。

     _________ is here gets a prize.      不管谁来,都能获奖。

    __________ I have done is only for you.     我所做的任何事都只是为了你。

_________ team will win the championship is uncertain.  哪支队会获得冠军还是未知数。

_________the meeting will be held hasn’t been decided.   在哪里举行会议还没定下来。

__________he will returned is the most important question.   他什么时候回来是最重要的问题

________they are reducing price does not matter。  他们为什么减价并不重要。

___________you do it is all right with me.    你无论怎样做这件事对我来说都行。

(4)由it作形式主语的几种情况:

It+系动词+名词+that从句。(常用的名词有a fact事实; an honor 荣耀; a wonder 奇迹; good news 好消息; an ashame 遗憾,耻辱; a pity遗憾; no wonder难怪; common sense常识)。

Eg: 难怪他取得了那么大的进步。It’s no wonder that he’s made so much progress.

你昨天没参加讲座真遗憾。__________________you didn’t attend the lecture yesterday.

It+系动词+形容词+that从句。(常用的形容词有:important重要的;likely可能的;unlikely不可能的;necessary需要的;natural自然的;strange奇怪的;obvious明显的;clear清晰的;certain明确的;wrong错误的;right正确的)。

Eg: 很可能明天会有一场暴雨。______________________there will be a heavy rain tomorrow.

真奇怪你竟然喜欢他。____________________you should like him.

It+不及物动词+that从句(常用的不及物动词有:seem似乎;happen发生,碰巧;seem看上去;显得appear

Eg: 他打电话时我碰巧不在家。It happened to me that I had been away when he called.

你好像不喜欢他。______________________you didn’t like him.

It+be+过去分词+that从句(常用的过去分词有:reported据报道;decided做出决定;said据说;advised有人建议;believed据信;announced有人宣布;told有人告诉;heard有人听说;hoped有人希望;thought有人认为;suggested有人建议;considered据认为;ordered根据命令;remembered有人记得;worked out制定出)

Eg: 据说他在国外学习。It is said that he is studying abroad.

据信艾滋病将在未来5年可以被治愈。_________________Aids can be cured in five years.

提示:以下两句型中,从句用should+动词原形,其中should可省略

It is necessary/important/strange/natural that+从句

It +be+suggested/advised/ordered/requested/insisted/required+that+从句

Eg  It is necessary that one master the skills of operating computers.

It was suggested they ___________ the project the next month.(start)

2、宾语从句:就是在复合句中作宾语的从句。引导词与主语从句的引导词大致一样,但注意形式宾语的用法。

Eg:  I don’t know which school he is in. 我不知道他在哪所学校。

  find, feel, think, consider, make, believe动词等后面有宾语补足语时,须用it做形式宾语而将that宾语从句后置,以此来保持句子平衡。

Eg:  I think it necessary that we take plenty of hot water every day.

我认为我们每天多喝水是有必要的。

(2)  有些动词如hate, like, dislike, appreciate等后跟when if引导的宾语从句时需要在宾语从句前加 it

EgI hate it when they talk with their mouths full of food.。

我讨厌他们满嘴食物时说话。

3. 表语从句在句中作表语,位于主句中的系动词如be之后,表语从句和主语同一内容,它对主语进行解释、说明,是主语的内容具体化。That在引导表语从句时无词义,常省略。

Eg: The trouble is that she has lost her money.   麻烦的事是她丢了钱。

提示:(1)主语为名词reason时,表语从句要用that, 不用why。

Eg: 这么严重的交通事故完全是由于司机太粗心、喝酒太多造成的。

The reason for such a serious accident is that the driver was too careless and drunk.

(2) 如主句的主语是idea, advice,suggestion,order, request,requirement等名词时,则表语从句的谓语要用虚拟语气,即“(should)+动词原形”的形式

eg:  My suggestion is that everyone should have his own dream.

4. 同位语从句:在复合句中用作同位语的从句称为同位语从句。一般由that(无词义,不充当成分), whether等连词引导, 常位于fact, news, idea, hope, problem, information, promise, suggestion, words, assumption等名词的后面,说明该词的具体内容。(参考三维)

提示:(1)有时可用namely(即), that is to say(也就是说),in other words(换句话说), that is(那就是), for example(例如)等引出同位语,说明其前面的名词或代词,例如:
