1、语法专练：名词性从句【考点透视】 在中学英语中，名词性从句是复合句中构成和分类最为复杂的部分。根据近年来高考英语命题的走向，今后它将仍然是考查的热点。其主要考点分布在：名词性从句的语序、名词性从句的连接词的辨析、有关名词性从句的常见句型等。名词性从句在句中的作用相当于名词，共有四种：主语从句、表语从句、宾语从句和同位语从句。引导名词性从句的连词有：连接代词：who，whose，whom，what，which。连接副词：when，where，why，how。其他连接词：that，whether，if，as if。 注意： 连接代词和连接副词在句中不是疑问词，因此从句中不用疑问式(即不要倒装)。

2、连接代词和连接副词在句中充当句子成分。连接词that，whether，if，as if在句中只起连接作用，不充当句子成分。（一）主语从句 主语从句在句中作主语，它可以放在主句谓语动词之前，但是当主语从句太长时，可以把它放在句子后部，前面用it作形式主语，如：It doesnt matter so much whether you will come or not. 你来还是不来，关系不大。(whether you will come or not是主语从句，it在句中作形式主语)（二）表语从句 表语从句在句中作表语，位于主句系动词之后。如： Thats why he was late. 注意：

3、表语从句还可用as if引导。如： She looked as if she was going to cry.（三）宾语从句 宾语从句在句子中作及物动词或介词宾语，在使用宾语从句时有以下几点需要注意： 1时态呼应：当主句谓语动词是过去时态，宾语从句要使用过去时态的某种形式。 2介词之后的宾语从句，一般不用if或which连接，要用what或whether。 3whether和if都可以引导动词之后的宾语从句，二者常可互换，但是在正式文体中或从句中有or not时，只用whether，不用if。4注意否定前移：当主句是I / We think (或suppose，expect，believe，

4、imagine，guess) 时，其后的宾语从句如果是否定的，常常把否定词not从从句移到主句。比较： I think you are not right. I dont think you are right. I believe they wont win the game.I dont believe they will win the game.（四）同位语从句 同位语从句一般跟在某些表示抽象概念的名词后面，用以说明名词所表示的具体内容。常跟同位语从句的名词主要有：idea，news，fact，promise，answer，belief，conditiondoubt，fear，hope
