名词性从句及练习.docx

1、名词性从句及练习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，名词性从句厅分为主语从句、表语从句、宾语从句和同位从句。（一）引导名词性从句的连接词 1、连接代词：who, whose, whom, what, which。有词义，在从句中担任成分，如主语、表语、宾语、或定语等。 2、连接副词：when, where, why, how。有词义，在从句中担任成分，作状语。 3、连接词：that, whether, if, as if。that 无词义，在从句中不担任成分，有时可省略；if (whether), as if虽有词义，但在从句中不担任成分。 注意：连接代词与连接

2、副词在句中不再是疑问句，因而从句中谓语不用疑问式。连接代词与连接副词在从句充当句子成分，连接词whether 和if（是否），as if（好象）在从句中不充当句子成分，只起连接作用。根据句义，如果连接代词与连接副词，whether、if 和as if都用不上时，才用that作连接词（that本身无任何含义）。（二）主语从句 1、主语从句在复合句作主语。 e.g. Who will go is not important. 2、用it作形式主语，主语从句放在句末。 e.g. It doesnt matter so much whether you will come or not. 3、that

3、引导主语从句时，不能省略。 e.g. That he suddenly fell ill last week made us surprised.（三）表语从句 1、表语从句在复合句中作表语，位于系动词之后。 e.g. The question was who could go there. 2、引导表语从句的连接词that有时可省去。 e.g. My idea is (that) we can get more comrades to help in the work.（四）宾语从句 1、宾语从句在复合句中作宾语。引导宾语从句的连词that一般可省略。e.g. I hope (that) e

4、verything is all right. 2、介词之后的宾语从句，不可用which或if连接，要分别用what或 whether。 e.g. Im interested in whether youve finished the work. Im interested in what youve said. 3、whether与if都可以引导宾语从句，常可互换。但下面情况不能互换。 宾语从句是否定句时，只用if，不用whether。 e.g. I wonder if it doesnt rain.用if 会引起误解，就要用whether。e.g. Please let me know w

5、hether you want to go.（此 句如果把whether改成if，容易当成条件句理解）宾语从句中的whether 与or not直接连用，就不能换成if；不直接连用，可换。e.g. I dont know whether or not the report is true. I dont know whether/ if the report is true or not.介词后的宾语从句要用whether引导。whether 可与不定式连用。whether也可引导主语从句、表语从句、同位语从句，还可引导让步状语从句，以上均不能换成if。但引导条件从句时，只能用if，而不能用w

6、hether。e.g.It depends on whether we have enough time.They dont know whether to go there.Please come to see me if you have time.（五）同位语从句同位语从句在句中作某一名词的同位语，一般位于该名词（如：news, fact, idea, suggestion, promise等）之后，说明该名词的具体内容。e.g. I have no idea when he will be back. The fact that he had not said anything sur

7、prised everybody.在历年的高考中几乎都涉及名词性从句，并且每年的命题各有变化，但仔细分析高考试题不难看出，这一部分内容主要从以下几个方面进行考查：1语序问题。在名词性从句中，除了关联词在从句之首外，其他部分应用陈述句的语序。She will give whoever needs help a warm support. Why he did that was not clear.2用it代替主语从句或宾语从句。为了使句子保持平衡，常用先行词it来代替主语从句或宾语从句，而把主语从句或宾语从句放到后面，尤其是that引导的主语从句常用于此种句式中，但what，whatever，w

8、hoever，whichever引导的主语从句一般不后置。3名词性从句中关联词的选择是非常重要的，所以在高考中更多的是考查关联词的选择，尤其是what用法要多体会。名词性从句高考真题探究（20062011年）【2011北京卷 22】_ Barbara Jones offers to her fans is honesty and happiness. A. Which B. What C.
