考英语复习：名词性从句课件.ppt

连接代词whoever，whatever，whichever可引导名词性从句，相当于anyone who, anything that等。它们也可以引导让步状语从句，相当于 no matter who/ what/ which。 Whoever breaks the law should be punished. 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. It looks as if it is going to rain. This is because he missed the train by one minute. 需要注意的是，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. 4. 同位语从句 同位语从句说明其前面的名词的具体内容。 同位语从句一般跟在某些表示抽象概念 的名词后,如 news, idea, information, fact, hope, thought, belief 等，用来说明名词所表示的具体内容， 引导同位语从句的连接词通常有that, whether和连接副词when, where, why, how；连接代词who，what，whose，which通常不引导同位语从句。 I have no idea when she will be back. The news that we won the game is exciting.　 The thought came to him that Mary had probably fallen ill. 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. Have you got the idea（that）this book gives you of life in ancient Greece？ (that引导同位语从句,不能省略） (that引导定语从句，作宾语，可以省略） 分析历届高考试题名词性从句考查的要点有以下六个方面: 1.考查名词性从句的语序问题 高考题例示： 1.
