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:
(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。
Eg:If he will succeed is not sure . (x)
(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:
_________ team will win the championship is
uncertain.
_________the meeting will be held hasn’t been
decided.
__________he will returned is the most important
question.
________they are reducing price does not
matter。
___________you do it is all right with
me.
(4)由it作形式主语的几种情况:
①It+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.
②It+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.
③It+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.
④It+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 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:
⑴
Eg:
我认为我们每天多喝水是有必要的。
(2)
Eg:I 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.
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:
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:
