名词性从句学生版.doc

名词性从句主语从句、表语从句、宾语从句、同位语从句，在整个句子中所起的作用，相当于一个名词。因此，这四种从句通称为名词性从句。历届高考试题名词性从句考查的焦点主要有以下六个方面：1. 考查名词性从句的语序问题2. 考查引导词that与what的区别 3. 考查it在名词性从句中作形式主语或形式宾语的用法4. 考查whether与if的区别 5. 考查名词性从句中的疑问词+ever引导的名词性从句与no matter+疑问词引导的状语从句的区别6. 考查名词性从句的虚拟语气问题引导名词性从句的连接词可分为三类： 连接词：that, whether, if （不充当从句的任何成分） 连接代词：what, whatever, who, whoever, whom, whose, which. 连接副词：when, where, how, whyI. 主语从句作句子主语的从句叫主语从句。主语从句通常由从属连词that，whether，if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，在从句中充当从句的成分。What he wants to tell us is not clear. It is known to us how he became a writer. Where the English evening will be held has not yet been announced. 有时为避免句子头重脚轻，常用形式主语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。主语从句后的谓语动词一般用单数形式。常用句型如下：（1）It + be + 名词 + that从句（2）It + be + 形容词 + that从句（3）It + be + 动词的过去分词 + that从句（4）It + 不及物动词 + that 从句另注意在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时，谓语动词要用虚拟语气“(should) +do”，常用的句型有：It is necessary (important, natural, strange, etc.) that It is a pity (a shame, no wonder, etc.) that It is suggested (requested, proposed, desired, etc.) thatII. 宾语从句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。在demand、order、suggest、decide、insist, desire, demand, 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“（should）+ 动词原形”。 I insist that she (should) do her work alone. The commander ordered that troops (should) set off at once. 2. 用who，whom, which, whose, what, when, where, why, how, whoever, whatever, whichever等关联词引导的宾语从句相当于特殊疑问句，注意句子语序要用陈述语序。I want to know what he has told you. She always thinks of how she can work well. She will give whoever needs help a warm support. 3. 用whether或if引导的宾语从句，其主语和谓语的顺序也不能颠倒，仍保持陈述句语序。此外，whether与if 在作“是否”的意思讲时在下列情况下一般只能用whether，不用if：a. 引导主语从句并在句首时；b. 引导表语从句时；c . 引导从句作介词宾语时；d. 从句后有“or not”时；e. 后接动词不定式时。Whether there is life on the moon is an interesting question. Everything depends on whether we have enough money. 4. think, believe, imagine, suppose等动词引起的否定性宾语从句中，要把上述主句中的动词变为否定式。即将从句中的否定形式移到主句中。We dont think you are here. I dont believe he will do so.III. 表语从句表语从句位于连系动词后，基本结构为：主语 + 系动词 + that从句。有时用as if引导。The fact is that we have lost the game. That is why he didnt come to the meeting.It looks as if it is going to rain.需要注意的，当主语是reason时，表语从句要用that引导而不是because。The reason why he was late was that he missed the train by one minute this morning IV. 同位语从句同位语从句通常由that引导，可用于同位语从句的名词有advice、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、truth、wish、word等。The news that we won the game is exciting.I have no idea when he will come back home. 我不知道他什么时候回来。The thought came to him that Mary had probably fallen ill. 他想到可能玛丽生病了。同位语从句和定语从句的区别： that作为关系代词，可以引导定语从句，充当句子成分，在从句中作宾语时可以省略； that引导同位语从句时，起连词的作用，没有实际意义，不充当句子成分，一般不能省略。 I had no idea that you were here（that引导同位语从句，不能省略）Have you got the idea（that）this book gives you of life in ancient Greece？（that引导定语从句，作宾语，可以省略）高考题链接1.（11北京）_ Barbara Jones offers to her fans is honesty and happiness.
