高三英语复习名词性从句补充讲义

高三英语复习名词性从句教案名词性从句讲义【主语从句及引导词】主语从句在复合句中作句子的主语。

引导主语从句的词有从属连词that, whether, if:连接代词who, whoever, whom, what, whatever, whose, which；连接畐H词when, where, how, why 等。

【例句呈现】观察下列例句，指出其中所包含的主语从句及引导词：1.What is needed for a long trip is careful preparation.该句中主语从句是_______________ ,引导词为______ O2.That Jay Zhou will come to my city excites everybod 该句中主语从句是______________ ,引导词为_______ o3.Whether we will travel abroad or not has not been decided.该句中主语从句是_______________ ,引导词为______ O4.Whoever knows the secret mustn' t tell others.该句中主语从句是_______________ ,引导词为______ O5.It remains a puzzle why dinosaurs died out suddenly long time ago.该句中主语从句是_______________ ,引导词为______ O【观察总结】通过分析上面例句，同学们可能会发现上面第5句中的主语从句似乎比较隐蔽。

其实，这也是主语从句的一种呈现方式，即：当一个句子主语过长时，可以用it作形式主语，而把真正的主语或主语从句后移至句子末尾，以保持句子的平衡。

注意观察下列例句中的划线部分：It is not clear how the accident happened.It is not hard to understand why he did so at that time.It is a pity that you should have made such a careless mistake.It is reported that more than thirty deaths were caused in the acciden 不难看出，虽然上面例句中都用it作形式主语，但句子结构却不尽相同。

高三英语语法复习---名词性从句一、概说名词性从句，即指性质相当于名词的从句，它包括主语从句、宾语从句、表语从句和同位语从句。

名词性从句的连接词的选用依据“从句缺什么成分补什么成分”的原则。

解题时，应首先确定选用连接代词还是连接副词。

然后再根据题意选用具体的连接词。

如果名词性从句中缺少主语、宾语、表语或定语，则选用连接代词。

如果从句中缺少状语，则选用连接副词。

如果从句中不缺成分，而仅表示陈述事实，则用that引导。

如果含有“是否”意义，则选用whether或if。

二、名词性从句的一般引导词1.连接词that 只起连接作用，没有任何意思，也不充当句子成分，在宾语从句中可省略，但引导其他名词性从句时通常不省略。

如：I hope (that) you enjoy your holiday. 希望你假期过得好。

That he likes you is very obvious. 很显然他喜欢你。

2.连接词whether 也不充当句子成分，但有自己的意思，表示“是否”；引导宾语从句时，可换成if，但引导其他名词性从句时不能换成if。

He asked whether [if] I would show him the way. 他问我是否可以给他带路。

Whether it will do us harm remains to be seen. 是否对我们有害还要看一看。

(引导主语从句，不能用if 代替whether)3.连接代词who(m), whose, which, what 等，均有各自的意义，在从句中作主语、宾语、定语等。

如：That’s why she wanted to leave. 这就是她想离开的原因。

When we arrive doesn't matter. 什么时候到没有关系。

Tell me which one you like best. 告诉我你最喜欢哪一个。

4.连接副词when, where, why, how 等，也各自有自己的意义，在从句中作状语。

一．概念：名词性从句就相当于一个名词（因为名词可以充当主语，宾语和表语，所以名词性从句包含主语从句，宾语从句和表语从句和同位语从句）二．名词性从句主语从句That she is beautiful is a fact.主语从句系定表宾语从句We know that she is beautiful.主谓宾语从句表语从句 Our opinion is that she is beautiful.主系表语从句同位语从句The opinion that she is beautiful is a fact.主同位语从句系定表三．名词性从句的格式 1. that+陈述句=名词宾1.结构：主语 + 谓语2.语序：陈述句语序3.连接词 :①由that 引导②由if /whether 引导know if / whether Hua likes fish.③由特殊疑问词引导，表示特殊疑问意义 I want to know what time it is now.4.时态①当主句是一般现在时，从句根据情况使用任何时态。

（即：主现从不限）I don’t know (that) she is singing now.②当主句是一般过去时，从句应使用过去某时态(一般过去时,过去进行时，过去将来时，过去完成时)。

He said (that) he was at home. 他说他在家里。

③主句使用一般过去时，但从句表示的是客观真理、自然现象时、从句仍用一般现在时。
