（PPT课件）第十八章 名词性从句-【解密英语】新高考实战语用语法

第十八章 名词性从句 在语篇中感知名词性从句 Whether there exist aliens on other planets has been puzzling us. Some people claim that they have found evidence that there are aliens in the universe, while others doubt if their proof is reliable or scientific. My answer to this question is that there may be aliens or there may be no such creatures. The universe is so vast that everything is possible. So far, no convincing proof has been provided to prove that there live aliens in other parts of the universe. Likewise, no solid evidence has been given to support that fact that there is none. What we should do is not arrive at any hasty conclusion but keep curious and collect more evidence. The reason is that our knowledge about the universe is limited and it is expanding all the time. If there do exist aliens, the next problem that we have to face is how we should interact with them. 第十八章 名词性从句 核心问题导学 1. 什么叫名词性从句？有哪几种名词性从句？ 2.名词性从句有哪些引导词？ 3.名词性从句的语序是什么？ 4.表语从句与宾语从句的区别是什么？ 5.同位语从句与定语从句的区别是什么？ 第十八章 名词性从句 一、名词性从句的概念与引导词 名词性从句在句中相当于一个名词（词组），在句中充当主语、表语、宾语或同位语。引导词有三种： 第一种：that，无词义，在句中不充当任何成分，其引导的句子相当于一个陈述句转化而来。在宾语从句中可以省略，主语从句后置也可以省略。 第二种：whether/if（是否），有词义，在从句中不作成分，其引导的从句相当于一个一般疑问句转化而来，不可省略。if一般只能引导宾语从句。 第三种：连接代词what, who, whom, whose, which, whatever, whoever, whomever等, 以及连接副词when, where, why, how soon, how often等，其后引导的句子相当于一个特殊疑问句转化而来。 第十八章 名词性从句 特别提醒：所有名词性从句都必须用陈述语气，不用疑问语气。 二、名词性从句的分类 （一）主语从句主语 从句就是作句子主语的从句。 That he saved the girl risking his own life is worth admiring. 他冒着自己的生命危险救那个女孩值得钦佩。 What he wants are some stamps. 他要的是一些邮票。 Whether he will be elected is not clear. 他是否会当选还不清楚。 Whoever breaks the law shall be punished. 无论谁违法都要受罚。 有时主语从句较长，为了使句子平衡，便用形式主语充当主语，而将主语从句后置。 It is certain (that) he will win. 他会赢，这是肯定的。 It is requested (that) the guest should give a performance. 客人被要求表演一个节目。 It proves/turns out that the experiment is successful. 实验证明是成功的。 第十八章 名词性从句 跟踪训练一 用不同的连接词填空。 1.
