主语从句
考点名称:主语从句
  • 主语从句:
    在复合句中充当主语成分的句子叫做主语从句。常规主语从句,即句子在复合句中充当一个主语。 主语从句的时态:不受主句的时态影响和限制。 
    例如:
    That he finished writing the composition in such a short time surprised  us all. 
    What we need is time. 
    It is certain that he will win the match. 
    (1) 引导主语从句连词有that,whether,who,what,whatever等    
    (2) 连词位于句首不能省略    
    (3) 主语从句大多数情况下视为第三人称单数
  • 主语从句引导词:
    1、由连词that引导的主语从句。
    例如:That you will win the medal seems unlikely.
    你想获得奖牌看起来是不可能的。
    That you are so indifferent bothers me.
    你如此冷淡使我很烦恼。
    That she survived the accident is a miracle.
    她在事故中幸免于难简直是奇迹。
    2、用连接代词或连接副词if, whether 引导的主语从句。
    例如: Which of them escaped from the prison is still a mystery.
    他们哪一个是从监狱里逃跑的,仍然是个谜。
    When they will come hasn’t been made pubic.
    他们什么时候来还不知道。
    Whether she is coming or not doesn’t matter too much.
    她来不来都无关紧要。
    3、用关系代词引导的主语从句。
    例如:What you need is more practice.

    What I want to know is this. 我想知道的就是这事。
    Whatever we do is to serve the people.
    我们无论做什么都是为人民服务。
    4、主语从句可以直接放在主语位置上,也可以用it作形式主语,而将从句放在句末(尤其是当谓语较短时)。
    例如:That light travels in straight lines is known to all.
    光沿直线传播,这是众所周知的事。
    =It is known to all that light travels in straight lines.
    众所周知光沿直线传播。
    When the plane is to take off has not been announced .
    飞机何时起飞还没有宣布。
    = It has not been announced when the plane is to take off.
    还没有宣布飞机何时起飞。
    当what引导的主语从句表示“…的东西”时,一般不用it作形式主语。
    错:It is a book what he wants.
    对:What he wants is a book. 他想要的是本书。
    如果带主语从句的句子是疑问式,则必须用it作形式主语的结构。
    例如:Has it been settled who will be sent to carry out the task ?
    谁将被派去执行这项任务决定了吗 ?
  • 主语从句与宾语从句区别:
    主语从句与宾语从句两者的用法和在句中的作用是不同的,下面从它们的各自用法来介绍。
    一.主语从句
    主语从句 定义:在句子中担当主语的是一个从句,这个从句就叫做主语从句。
    主语从句是在复合句中充当主语的从句,通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。
    1. It 作形式主语和it引导强调句的比较
    ①主语从句常用it作形式主语,一般常用句型为:It is+{名词/形容词/过去分词}+主语从句例如:
    It is still a question whether she will come or not.
    It is strange that you should like him.
    It is still unknown which team will win the match.
    另外,还有一些比较多见的结构:
    It turned out that……;
    It has been proved that……;
    It happened/occurred that……;
    It is well-known that……等等
    ②而强调句则不同,它的结构是:It+be+被强调部分+that+从句
    强调主语:It is the times that produce their heroes.时势造英雄
    强调宾语:It is English that Prof.Lin teaches us.
    强调状语:It was in shanghai that I saw the film.
    判断是否是强调句有一个方法,就是将that以后的“句子的其余部分”拿出来单独看,看有没有缺成分,缺的是什么成分,再把谓语动词后面that前面的那部分,带到你认为缺成分的地方,如果放进去是一句完整的句子了,那就说明是强调句。

    2. 用it 作形式主语的结构
    (1) It is +名词+that从句
    It is a fact that … 事实是……
    It is an honor that …非常荣幸
    It is common knowledge that …是常识
    (2) it is +形容词+that从句
    It is natural that… 很自然……
    It is strange that… 奇怪的是……
    (3) it +不及物动词+that从句
    It seems that… 似乎……
    It happened that… 碰巧……
    (4) it is+过去分词+that从句
    It is reported that… 据报道……
    It has been proved that… 已证实……

    3.主语从句不可位于句首的五种情况
    (1) if 引导的主语从句不可居于复合句句首。
    (2) It is said , (reported) …结构中的主语从句不可提前。例如:
    It is said that President Jingo will visit our school next week.
    (3) It happens…, It occurs… 结构中的主语从句不可提前。例如:
    It occurred to him that he failed in the examination.
    (4) It doesn’t matter how/whether …结构中的主语从句不可提前。例如:
    It doesn’t matter whether he is wrong or not.
    (5) 含主语从句的复合句是疑问句时,主语从句不可提前。例如:
    Is it likely that it will rain in the evening?

    4. What 与that 在引导主语从句时的区别
    What 引导主语从句时在从句中充当句子成分,如主语.宾语.表语,而that 则不然。例如:
    What you said yesterday is right.

    宾语从句用以区分主语从句的几个特征:
    1、引导词:what\which\whose\when\whether\if\where

    2、语序:宾语从句必须是用陈述语句。
    如:I think that you must work harder.
    宾语从句的引导词、连接词的区别、否定转移等现象。
    (1)表达时间的几个句型:一般用when或者是what time:
    What time will the train leave?
    由于时刻都是固定的,也可以用一般现在时代替一般将来时:
    What time does the train leave?
    (2)时间的表达方式:8:19(nineteen past eight),7:57(three to eight),在时间的中间也可以加上分的单词(minutes)
    (3)had better +动词原型。意思是提要求,建议。但是上下级不能用这种方式,因为语气太重:
    You had better give up smoking .
    (4)sb leave sth +地点
    I left my book in my classroom yesterday.
    (5)may I have your name(address\age)?一般询问对方的年龄、名字等,不要习惯以前的问法,这样很不礼貌,而是要采访上面的问法。
    以前的习惯是:how old are you? \what's your name?
    (6)修饰名词的代词次序:限-描-大-形---年---颜----籍----物--------类+名词:
    this is a bridge.
    This is a beautiful bridge
    补充:从句的语序永远是陈述句。
  • 主语从句结构:
    1、It is +名词+从句
    It is a fact that… 事实是……
    It is good news that … ……是好消息
    It is a question that … ……是个问题
    It is common knowledge that … ……是常识
    类似的名词还有:a pity;a wonder;a good thing; no wonder; surprise等。
    例如:It is a mystery to me how it all happened.
    这一切是怎么发生的是个谜。
    It is common knowledge that the whale is not a fish.
    鲸鱼不是鱼,这是常识。
    It is no surprise that Bob should have won the game.
    鲍勃会赢得这场比赛,这不足为奇。

    2、It is +形容词+从句

    3、It is +过去分词+从句

    It is reported that … 据报道……
    It has been proved that … 已证明……
    It must be proved that… 必须指出……
