2015年高考名词性从句经典讲解(含完成句子练习及答案).doc

名词性从句 带有从句的复合句就是用连接词把主句和从句连接在一起。高中英语中共有三大从句： 一、形容词性从句（即定语从句）；二、名词性从句；三、状语从句。 形容词性从句即定语从句，相当于一个形容词，作先行词的定语，用来修饰前面的名词或代词的。名词性从句相当于名词，可分别作主句的主语、表语、宾语和同位语。因此，名词性从句分为主语从句、表语从句、宾语从句和同位从句。主语从句、表语从句、宾语从句只有在主句句子的成分残缺时才可以考虑使用这三大从句。同位语则是对前面某一名词的展开，即对前一名词的具体说明，做进一步解释，两者是同等，并不是定语从句的修饰与被修饰关系。 （一）主语从句 第一部分：常规主语从句，即从句在复合句中充当一个主语。主语从句的时态：不受主句时态的影响和限制。 What he wants to tell us is not clear. 他要跟我们说什么，还不清楚。 Who will win the match is still unknown. 谁能赢得这场比赛还不得而知。 Where the English evening will be held has not yet been announced. 英语晚会将在哪里举行，还没有宣布。 注意：(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)主语从句后的谓语动词一般用单数形式。 第二部分：为了防止句子头重脚轻，通常把形式主语it放在主语位置，真正主语置于句末。从句用that引导。 常用句型如下： It + be + 名词 + that从句 It is a pity that we wont be able to go to the south to spend our summer vacation. It is still a mystery what caused the accident. It + be + 形容词 + that从句 It is certain that he will win the match. It is very likely that they will hold a meeting. It + be + 动词的过去分词 + that从句 It is said that he has gone to shanghai.(=He is said to have gone to shanghai) It is known to all that the gun powder was first invented by the Chinese. It + 不及物动词 + that 从句 It seems that he has seen the film.(=He seems to have seen the film) It happened that the two cheats were there. (=The two cheats happened to be there) 【注意】 在表示惊讶、喜悦、遗憾等感情色彩时，that从句中的谓语动词也常用 (should) + v原形。 It is necessary (important, natural, strange, etc.) that … 在表示建议、要求、命令等意义的被动结构中，that从句中的谓语动词常用(should) do。 It is suggested (requested, proposed, desired, etc.) that… e.g. It is strange that he should do that. It is important that we all should attend the meeting. It is suggested that the work should be done with great care. （二）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。 The problem is how we can get the things we need.问题是我们怎样能弄到我们需要的东西。(how充当方式状语) The scissors are not what I need. 这把剪刀不是我所需要的。(what 在表语从句中充当宾语) What I told him was that I would find him a good play. 我告诉他的是我会给他找个好剧本。(what在主语从句中作直接宾语， that作为表语从句的引导词在该表语从句中不充当句子成分， 不能省略) Th
