名词性从句讲解与练习

1、名词性从句讲解与练习名词性从句包括主语从句，宾语从句，表语从句，同位语从句，它既是高中英语教学的重点与难点，又是高考的热点。名词性从句侧重考查学生在一定的语言环境中对该类从句的语序，从句连接词的使用以及主从句时态的呼应等知识的掌握。辨别下列从句1.Whether he will come or not is unknown. 2.Its unknown whether he will come or not.3.I dont know whether or not he will come.4.The question is whether he will come or not 5.That

3、said at the meeting.13.I have no idea what he said at the meeting.II 名词性从句的引导词很多，归纳起来分为一下三类。 1 连接词。只起连接作用，不充当从句中的任何句子成分。如that, whether, if.注意：在主语从句，表语从句，同位语从句中表“是否”之意时，要用“whether”不用“if”. 2 连接代词。既起连接作用，本身又作从句中的主语，宾语，表语或定语，如who,whom,whose,which,that. 3 连接副词。既起连接作用，本身又作从句中的状语，如when,where,how,why.考点一 th

4、at与what, what与which 在引导名词性从句时的区别。1 that与whatthat在引导名词性从句时，不在从句中作成分，不含任何意义，只起连接作用，在句首时不可省略。what在引导名词性从句时，既起连接作用，又要在从句中作主语，宾语或表语，在任何情况下它都不能省略，它有具体意义，表示“所-的（物，事，话等）”或“-的”相当于all that, everything that.例如：1)What you have done might do harmful to others. 2) I think (that) you will like the stamps.2 What与wh

5、ich what与which在引导名词性从句中，都要在从句中作成分，都有实际意义，但是which在名词性从句中表选择，而what表意较笼统。注意whichever, whatever在引导名词性从句时的区别与它们相同。例如：1）What we cant get seems better than what we have.（表意笼统） 2) Here are 5 pairs, can you tell me which you would like to buy?（表示从供选的5双中作选择）1）（2012湖北，80）Things arent always _they appear.事情往往不是
