表语从句
的有关信息介绍如下:表语从句是在复合句中充当表语的从句,其作用是说明主语是什么。表语从句可以由多种引导词引导,包括that, whether, 连接代词和连接副词,以及as if, as though, because等连词。表语从句中的引导词在句中不担任句子成分,无实际意义,但引导表语从句。例如,使用that引导的表语从句有“The fact is that he doesn’t really try.”和“The trouble is that I have lost his address.”等。在非正式文体中,表语从句中的that有时可以省略,但在正式文体中通常不省略。表语从句的引导词在句中的使用有一定的规则。例如,whether可引导表语从句,但与之同义的if通常不用于引导表语从句;because可引导表语从句,但与之同义的since, as, for等也不用于引导表语从句。表语从句的例句包括但不限于:“The fact is that he doesn’t really try.”“The trouble is that I have lost his address.”“My suggestion is that we should tell him.”“What the teacher really doubts is whether my mother will come to school soon.”“The problem is how we can find him.”这些例句展示了表语从句在实际语境中的应用,通过不同的引导词和句子结构,表达了不同的信息和意义。表语从句的学习有助于更深入理解英语语法结构,提高语言运用能力。
