等考点的理解。关于这些考点您可以点击下面的选项卡查看详细档案。
  • 不定式的被动式
  • 同位语从句

不定式的被动式的概念:

如果不定式的逻辑主语是不定式所表示的动作的承受者,不定式要用被动式。如:The next thing to be done is to get our classroom pained.


不定式被动式的用法:

一、基本形式:
不定式被动式的基本形式为to be done;若表示动作先于另一动作之前,则用完成式,即to have been done。

二、用法归纳:
不定式被动式在句中可以用作:
1、主语:
如:It's a great honour to be invited to the banquet. 承蒙邀请赴宴,甚是荣幸。
        To be attacked by the enemy is not a bad thing, but a good tiring. 被敌人反对是好事,不是坏事。
        It's a pity to be kept in the house in fine weather. 好天气时被留在家里是很遗憾的。
2、表语:
如:All this is to be sold. 所有这些都是出售的。
        Water must be pure if it is to be drunk. 水如供饮用必须净化。
        The switchboard is to be manned at all times. 任何时候电话总机那儿都应有专人在岗负责。
3、宾语:
如:She doesn't want to be separated from him. 她不愿和他分开。
        He begged to be allowed to return to Brazil. 他恳求允许他返回巴西。
        I don't wish to be disturbed in my work. 在工作时我不愿意被人打扰。
        They demanded to be shown the authentic documents. 他们要求出示真实可靠的文件。
4、定语:
如:I made notes of the things to be mended. 我记下了需要修补的东西。
       The Blacks are the first to be fired and the last to be hired. 黑人是最先被解雇,最后被雇用。
5、状语:
如:He asked to be kept in formed about developments. 他要求随时向他报告发展情况。
        As she waited to be served, she became very impatient. 她在等候侍者送饭时,很不耐烦。
        She got there only to be told that they had gone on holiday. 她到达那里,被告知他们度假去了。
6、宾语补足语:
如:He did not like his intention to be laughed at. 他不喜欢自己的意图受到嘲笑。
        He ordered the goods to be sent by air. 他命令把货物空运
7、主语补足语:
如:The court was ordered to be cleared. 有命令要关闭法庭。
        The books are not allowed to be taken out of the room. 不许将书携出室外。
8、用在“for+名(代)词+不定式”结构中。
如:It's an honour for me to be asked to speak here. 我很荣幸被邀在这里讲话。
        It is essential for him to be prepared for this. 有必要让他对此有所准备。
        It's impossible for the job to be finished in time. 这项任务要按时完成是不可能的。
        The note was a simple request for a porter to be sent to room201. 这个字条就是请指派一个搬运工到201室去。
        Can you arrange for the gold to be delivered on Monday? 你能不能安排一下周一把金子送到?


动词不定式的被动式之注意点:

 一、注意形式与功用:
不定式的被动式为“to be+过去分词”,表示其逻辑主语是动作的承受者,具有被动含义。在句中可用作主语、表语、宾语、定语、状语、补语等。
如:It was impossible for lost time to be made up. 要弥补已失去的时光是不可能的。
        I hope to be invited to the party. 我希望有人请我去参加晚会。
        Have you got ready for the meeting to be held? 你为即将举行的会议准备好了吗? 
        In order to be chosen, he sent each of them a present.为 了被选中,他给他们每人都送了礼物。
        The problem seems to be solved soon. 问题好像快要解决了。

二、与不定式的主动式的比较:
1、表示义务的概念,句子的主语是要做的动作或接受动作的人或物时,要用不定式的被动式。
如:These sheets are to be washed. 这些床单要洗一洗。
        The cleaning is to be finished by mid day. 要在中午前打扫完毕。
2、不定式作定语与被修饰词是主谓、动宾、同位等逻辑关系时,多用其主动式。
如:Where is the boy to speak at tomorrow's meeting?(=who will speak at tomorrow's meeting主谓关系) 明天要在会上发言的那个男孩在哪里? 
        I have got a letter to write.(=that I will write动宾关系,尤其谓语动词为have, give, bring等时) 我有封信要写。
       Give me a pen to write with.(=that I can write with不及物动词加上相应的介词)给我一枝笔写。
注意:如果动作的执行者在主语或宾语中没有出现,应用不定式的被动式。
如:I'm going to the post office. Do you have any letters to be posted? 我要去邮局。你有信要寄吗?(动作执行者不是you)
3、在there be结构中,用不定式的主动式和被动式意义一般差别不大,但有些还是有差别的。
如:There's a lot to be said (或to say) about this book. 关于这本书大有可说。
        There is nothing to see. 没有什么可看的了。
        There is nothing to be seen. 看不见有什么。(即“什么也没看见”)
4、修饰作表语或宾补的形容词的不定式,常用主动式表示被动含义。
如:I don't think English hard to learn. 我认为英语不太难学。

三、双重被动结构有些被动结构后接不定式作宾语、宾语补足语等时,仍然含有被动含义,就得用双重被动结构:
如:The work is thought to be finished soon. 大家认为工作很快就完成了。

四、动作发生的时间不定式多表示未来动作或情况,其被动式也不例外,上述各例皆有体现,尤其是改为定语从句时多为将来时的被动语态。另外我们还要注意以下两点:
1、表示被动关系时,当不定式的动作先于谓语时,可用不定式的被动式的完成时:to have been done;
与谓语同时进行时,要用不定式的被动式的进行时:to be being done。
如:The dead woman is said to have been badly treated. 据说死去的妇女受虐待。
        Rain forests are reported to be being cut down rapidly. 据报道雨林正被迅速地砍伐。
2、不定式的主动式作含序数词的被修饰词语的定语时,可表示已完成的动作。
如:He was the first man to taste the tomato. 他是第一位品尝西红柿的人。
        They were the last to leave the countryside.他们是最后一批离开农村的。


同位语从句的概念:

在复合句中充当同位语的名词性从句称为同位语从句。同位语从句是名词性从句(主语从句、表语从句、宾语从句、同位语从句)中的主要从句之一,从句作同位语表示与之同位的名词(短语)的实际内容,它的作用相当于名词,对前面的名词(短语)加以补充说明或进一步解释,相当于一个表语从句,它们之间的关系是同位关系,即主表关系。


同位语从句的用法:

1、同位语从句的引导:
词引导同位语从句的词语通常有连词that,whether,连接代词和连接副词等:
如:We heard the news that our team had won. 我们听到消息说我们队赢了。   
        They were worried over the fact that you were sick. 他们为你生病发愁。 
        I have no idea when he will come back. 我不知道他什么时候回来。
        There is some doubt whether he will come. 他是否会来还不一定。 
        The question whether it is right or wrong depends on the result. 这个是对还是错要看结果。
:whether可引导同位语从句,但if不能引导同位语从句。

2、同位语从句与定语从句的区别:
(1)意义的不同:
 同位语从句是用于说明所修饰名词的具体内容的,它与被修饰词语通常可以划等号;而定语从句是限制所修饰名词的,它的作用是将所修饰的名词与其他类似的东西区别开来:
如:We are glad at the news that he will come. 听到他要来这个消息我们很高兴。
(news的内容就是that he will come,故that引导的是同位语从句)
        We are glad at the news that he told us. 听到他告诉我们的这个消息我们很高兴。
(that从句是限制thenews的内容的,即我们高兴只是因为他告诉的这个news而不是其他的news,故that从句为定语从句)
(2)引导词的不同:
          what, how, if, whatever等可引导名词性从句,但不引导定语从句。
(3)引导词的功能上的不同:
          that引导同位语从句时,它不充当句子成分,而引导定语从句时,它作为关系代词,要么充当定语从句的主语,要么充当定语从句的宾语。
如上例that he told us中的that就充当told的宾语。
(4)被修饰词语的区别:
          同位语从句所修饰的名词比较有限,通常有hope, wish, idea, news, fact, promise, opinion, suggestion, truth等,而定语从句所修饰的名词则非常广泛。
另外,when和where引导定语从句时,通常只修饰表示时间和地点的名词,而它们引导同位语从句时却不一定;又如why引导定语从句,它通常只修饰名词thereason,而它引导同位语从句时则不一定:
如:I have no idea when they will come. 我不知道他们什么时候来。(同位语从句)
        I'll never forget the days when I lived there. 我永远不会忘记我住在那儿的日子。(定语从句)
        We don't understand the problem why this is the best choice. 我们不明白这个问题,为什么这是最好的选择。(同位语从句)
        There a son why he didn't come to the meeting is that he is ill. 他未能来开会,原因是他生病了。(定语从句)


同位语从句用法解析:

一、理解同位语从句的含义,把握同位语从句的实质:  
在主从复合句中作同位语的从句称为同位语从句。同位语从句一般用that, whether, what, which, who, when, where, why, how等词引导,常放在fact, news, idea, truth, hope, problem, information, wish, promise, answer, evidence, report, explanation, suggestion, conclusion, word, possibility等抽象名词后面,说明该名词的具体内容。换言之,同位语从句和所修饰的名词在内容上为同一关系,对其内容作进一步说明。
例:The news that they had won the game soon spread over the whole school. 他们比赛获胜的消息很快传遍了整个学校。
析:they had won the game说明the news的全部内容,因此该句为同位语从句。

二、正确运用同位语从句的引导词,准确把握同位语从句:
1、如同位语从句意义完整,应用that引导同位语从句。(即that不充当任何成分,只起连接作用,不可省略) 
例:The general gave the order that the soldiers should cross the river at once. 将军下达了战士们立即过河的命令。 
析:the soldiers should cross the river at once是the order的全部内容,且意义完整,因此应用that引导同位语从句。
2、如同位语从句意义不完整,需增加"是否"的含义,应用whether引导同位语从句。(if不能引导同位语从句)
例:We'll discuss the problem whether the sports meeting will be held on time. 我们将讨论运动会是否会如期举行的问题。
析:the sports meeting will be held on time 意义不完整,应加“是否”的含义才能表达the problem的全部内容,因此应用whether引导同位语从句。
3、如同位语从句意义不完整,需增加"什么时候"、"什么地点"、"什么方式"等含义,应用when, where, how等词引导同位语从句。 
例1:I have no idea when he will be back.  
析:he will be back 意义不完整,应加"什么时候"的含义才能表达idea的全部内容,因此应用when引导同位语从句。 
例2:I have no impression how he went home, perhaps by bike.
析:he went home 意义不完整,应加"如何"的含义才能表达impression的全部内容,因此应用how引导同位语从句。
4、当主句的谓语较短,而同位语从句较长时,同位语从句常后置。
如:The thought came to him that may be the enemy had fled the city.
