名词性从句——连接词选用
名词性从句
名词性从句在句子中起名词作用的句子叫名词从句(Noun Clauses）。
名词从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能，名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。
一、引导名词性从句的连接词引导名词性从句的连接词可分为三类：连词：that（无任何词意）whether, if（均表示“是否”表明从句内容的不确定性）as if ,as though（均表示“好像”，“似乎”）以上在从句中均不充当任何成分连接代词：what, whatever, who, whoever, whom,whose, which, whichever, whomever连接副词：when, where, how, why1．宾语从句考点之一、宾语从句的语序无论宾语从句的主句是陈述句还是疑问句，也无论主从句间是什么引导词，宾语从句一律用陈述语序，即“引导词+主语+谓语+其它”。
例如：Could you tell me where Wei Fang lives?当疑问代词who, what等在从句中作主语时，语序本来就是陈述语序，故语序不再变化。
例如：Please tell us who will give us a talk.考点之二、宾语从句的时态从下面三个方面去把握宾语从句的时态。
1、当主句的时态是一般现在时、一般将来时、祈使句时，从句的时态可根据句意的需要用任意一种时态。
例如：I know that he'll come back in an hour.2、当主句的时态为一般过去时，从句要用过去时的相应时态。
例如：He said that he would go to Beijing.3、当宾语从句叙述的是客观事实、真理、自然现象、名言警句、谚语等，不管主句是什么时态，从句一律用一般现在时。
例如：The teacher said that the moon goes around the earth yesterday.The teacher told his class that light travels faster than sound.考点之三、宾语从句的连接词1、从属连词主要有that, if, whether表示陈述语气用that, 表示一般疑问语气，含有“是否,能否”的意思whether 和if引导。

名词性从句的语态和连接词选择
名词性从句的语态和连接词选择名词性从句是英语中一种常见的句型，它可以作为主语、宾语、表语或同位语。
在使用名词性从句时，我们需要注意选择适当的语态和连接词来构建句子。
本文将探讨名词性从句的语态和连接词选择，以帮助读者更好地理解和运用这一句型。
一、名词性从句的语态选择名词性从句的语态通常有两种选择，即完成语态和不定式语态。
选择哪种语态取决于主句的时态和语义。
1. 完成语态当主句是现在时或将来时，并且名词性从句表示的动作发生在主句谓语动词之前时，可以使用完成语态。
例如：- It is important that the work has been completed before the deadline.- I insist that the assignment has been submitted on time.2. 不定式语态当主句是过去时，并且名词性从句表示的动作在主句谓语动词之后时，通常使用不定式语态。
例如：- He knew that he had to finish the project before Friday.- She realized that she needed to improve her English skills.需要注意的是，如果主句是过去时，但名词性从句表示的动作与主句谓语动词同时发生或在之前发生，也可以使用完成语态。
例如：- I realized that I had made a mistake.- He said that he had visited the museum yesterday.二、名词性从句的连接词选择名词性从句的连接词决定了从句在句子中的作用和语义关系。
常见的名词性从句连接词包括关系代词（who, whom, which, whose, that）、连词（that, whether）、副词（when, where, why, how）等。
