【名词性从句】是英语语法中的一个重要概念,它指的是在句子中起到名词作用的从句,能够充当主句的主语、宾语、表语或同位语。本资料详细解析了牛津英语模块三中的名词性从句,并提供了高考相关的练习题目。
**名词性从句的类型**:
1. **主语从句**:从句作为主句的主语,如"That you don’t like him has nothing to do with me."。
2. **宾语从句**:从句作为动词或介词的宾语,如"Whether John can do the experiment remains a question."。
3. **表语从句**:从句作为系动词的表语,如"What surprised me most was that such a little girl can play the violin so well."。
4. **同位语从句**:与名词紧密相关,进一步解释该名词的内容,例如"The news that he won the prize is true."。
**名词性从句的引导词**:
1. **连接代词**:who, whom, whose, what, which, whoever, whatever等,它们在从句中充当成分,如"Who will be sent abroad to further his studies is not announced."。
2. **连接副词**:when, where, why, how等,同样在从句中充当成分,如"It happened that I was a witness to the accident."。
3. **从属连词**:that, whether, if,其中as if和because仅用于引导表语从句。
**主语从句的特殊用法**:
1. 当主语从句过长时,常使用it作为形式主语,将真正的主语从句后置,如"It is certain that she will do well in the exam."。
2. 具体句型包括"It + be + 形容词/名词词组/过去分词 + that 从句"以及"It + seem/ happen/look as if + that 从句"。
**高考名词性从句试题示例**:
1. "___________ you don’t like him is none of my business." 此题答案为C. That,因为从句本身完整,不缺成分,且作为主语从句。
2. "___________ is a fact that English is accepted as an international language." 此题答案为D. It,这是一个典型的"it + be + a fact + that"结构,it是形式主语。
3. "___________ we’ll go camping tomorrow depends on the weather." 此题答案为B. Whether,因为从句表达了不确定的情况,适合用whether引导。
4. "___________ worries me the way he keeps changing his mind." 此题答案为C. What,what在此处作主语从句的主语。
5. "It is none of your business other people think about you. Believe yourself." 此题答案为B. what,what引导的从句作介词about的宾语。
6. "_______ matters most in learning English",根据句意,此处应填入"什么",即"What",引导主语从句,表示"在学习英语中最重要的是什么"。
这些题目展示了名词性从句在实际应用中的多样性和重要性,理解和掌握这一语法点对于提升英语阅读理解、写作和表达能力具有重要意义。通过类似题目的练习,学生可以更好地运用名词性从句,提高语言表达的准确性和复杂度。
