[英语]名词性从句.pptVIP

3. 表语从句 在句中作表语的句子叫表语从句。 引导表语从句的关联词与引导主语从句的关联词大致一样，表语从句位于连系动词后，有时用as if, because 引导。其基本结构为： 主语 + 系动词 + that从句 The fact is that we have lost the game. That’s just what I want. This is where our problem lies. That is why he didn’t come to the meeting. * 在复合句中起名词作用的从句叫做名词性从句。 名词性从句 主语从句 表语从句 宾语从句 同位语从句 that, whether, if, because as if /as though（不充当从句的任何成分） 连接词 how, why, when, where however, wherever 连接副词 who, whom, whose, which, what, whatever 连接代词 引导名词性从句的连词 在名词性从句中一律用陈述句的语序，即使从句表达的是疑问含义。 The problem is what he has said at the meeting. 1. 主语从句 由句子充当主语叫主语从句。 主语从句通常由从属连词that，whether 和连接代词what, who, which, whatever, whoever以及连接副词how,when,where, why等词引导。 that在从句中无词义，只起连接作用；连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用，在从句中充当成分。 What he wants to tell us is not clear. Who will win the match is still unknown. Where the English evening will be held has not yet been announced. That he stole a bike was true. 单个的主语从句作主语时，谓语动词用单数形式。如果是两个或两个以上的主语从句作主语，谓语动词则用复数形式。 Where and when he was born has not been found. When the person was murdered and why he was murdered are still unknown. 有时为避免句子头重脚轻，常用it 代替主语从句作形式主语放于句首，而把主语从句置于句末。主句的谓语动词一般用单数形式。常用句型如下： It is +名词＋从句 It is a pity that we can’t go. b. It is ＋形容词＋从句 It is clear that Tom has returned. c. It is ＋过去分词＋从句 It is said / reported / believed / known … It is said that he went abroad last month. It is a pity that… it’s a shame that… It’s no wonder that… It is suggested that… It’s requested that… It’s proposed that…, It’s desired that… 2. 宾语从句 用句子作宾语的从句叫宾语从句。 引导宾语从句的关联词与引导主语从句表语从句的关联词大致一样，在句中可以作谓语动词或介词及非谓语动词的宾语。 1.)由连接词that引导的宾语从句 由连接词that引导宾语从句时，that在句中不担任任何成分，在口语或非正式的文体中常被省去，但如从句是并列句时,第二个分句前的that不可省。 He has told me that he will go to Shanghai tomorrow. We must never think (that) we are good in everything while others are good in nothing. 注意:在demand, order, suggest, advise, decide, insist, desire, request, command等表示要求、命令、建议、决定等意义的动词后，宾语从句常用 “主语+should+ 动词原形
