名词性从句 讲义-2024届高三英语语法一轮复习考点

2024届高三英语高考一轮复习语法考点 名词性从句（讲义) 英语中从句主要分为三种：名词性从句（用从句代替名词）、定语从 句（用从句代替形容词）、状语从句（用从句代替副词）。名词性从句就 是指从句在主句中充当名词成分，其功能相当于名词性词组。 1)根据从句在句子中不同的语法功能，名词性从句可分为：主语从 句、宾语从句、表语从句和同位语从句。 2)根据名词性从句的引导词不同，可分为：that从句、if/whether从 句和wh-引导的疑问句 (who/whom/whose/whoever/what/whatever/which/whichever/where/when/ho w/why等)。 一、主语从句(Subject Clause) 主语从句顾名思义就是从句在句子中充当主语成分。 如以下划线部分在句子中做主语成分： Who will take over the work makes no difference. Whoever smelt it dealt with it. What moved him was a sense of those worlds around us. Whatever you decide to do is fine with me. How you made that decision baffles me. Why we chose not to include you is none of your business Where the candy bar is hidden remains a mystery. That she worked hard for the whole term pleased her parents How we remember.what we remember.and why we remember form the most personal map of our individuality. 注意事项： 1.如果主语从句放在句首表示“是否”的时候，不能用f只能有 Whethero 正确：Whether Mary really heard him is really doubtful. 错误：If Mary really heard him is really doubtful.. 2.为了防止句子头重脚轻，常常用“t”做形式主语放在句首，真正主语 搁置于句末。 如： Who will be in charge of the project hasn't been decided yet. 变为：It hasn't be decided who will be in charge of the project,. What caused the plan crash is still a mystery. a变为：It is still a mystery what caused the plan crash. 个别结构的主语从句只能用t做形式主语进行引导。包括： It is said/reported that...s结构，It happens/occurs to/hits/strikes sb..that.… 结构等。 如： It is said that the CEO will visit our department next week. 错误：That the CEO will visit our department next week is said. It struck him that he had an exam tomorrow. 错误：That he had an exam tomorrow struck him, 二、宾语从句(Object Clause) 宾语从句就是从句在句子中充当宾语成分。 1.若从句为陈述句，常用that引导。连接宾语从句的连词that常省 略。如： He told me (that)he would lent his whole collection of Harry Potter stickers to me. They pretended (that)they know the answers to all the problems. 2.若从句为一般疑问句，则可用whether或if引导，表示“是否”。但 以下情况，只能用whether,不用if引导： 1)whether.or/or结构中。 I don't know whether/if he will attend the meeting. I don't know whether he will attend the meeting
