高考名词性从句精讲精练：主语从句、宾语从句、表语从句&同位语从句 高考英语语法：名词性从句精讲 名词性从句是在句子中起名词作用的从句，包括主语从句、宾语从句、表语从句和同位语从句。 一、主语从句 1.位置：通常位于句首，但有时为了避免句子头重脚轻，会用 it 作形式主语，真正的主语从句放在句末。 例如：That he will come is certain. （直接位于句首） 例如：It is certain that he will come. （it 作形式主语） 2.引导词：that（无词义，在从句中不充当成分）、whether（是否）、连接代词（what, who, which, whose 等）、连接副词（when, where, why, how 等） 二、宾语从句 1.位置：位于及物动词、介词或某些形容词后。 例如：I believe that he is honest. （及物动词后） 例如：He is worried about what he should do. （介词后） 2.时态：宾语从句的时态要根据主句的时态来确定。 （1）主句是一般现在时，从句根据实际情况用各种时态。 （2）主句是一般过去时，从句要用相应的过去时态（一般过去时、过去进行时、过去将来时、过去完成时）。 （3）但如果从句表示的是客观真理、自然现象等，从句时态用一般现在时。 语序：宾语从句要用陈述句语序。 三、表语从句 位置：位于系动词之后。 例如：The problem is that we don't have enough money. 引导词：与主语从句基本相同。 四、同位语从句 1.位置：通常跟在名词后面，对该名词的内容进行解释说明。 例如：The news that he won the game is exciting. （“that he won the game”解释“news”的内容） 2.特点：同位语从句与先行词在逻辑上是“同位”关系，即从句所表达的内容就是先行词的具体内容。 3.引导词：that（无词义，在从句中不充当成分）、whether（是否），少数情况下可用连接代词和连接副词。 高考常见考点和易错点 1.连接词的选择：要根据从句的成分和意义来准确判断使用哪个连接词。 2.语序问题：名词性从句都要用陈述句语序。 3.时态呼应：注意主句和从句时态的一致性。 专项练习 一、单项选择 1._________ makes the book so extraordinary is the creative imagination of the writer.
