2024届高三英语一轮复习：名词性从句讲义素材

名词性从句 一、主语从句 主语从句是在复合句中担任主语的句子。其特点有： （1）引导词： 从属连词 that, whether； 连接代词 who, what, which；whoever, whatever, whichever; 连接副词 when, where, how和why。 语序：陈述句语序 That he will win the match is certain. It is certain that he will win the match. （3）在主语从句中只能用whether，不能用if 1. 一般来说主语从句都是放在句首，但有时为了使句子保持平衡，避免"头重脚轻"，常用it作形式主语，从而把主语从句放后面。常以it作形式主语的句型有： ①It is＋形容词＋that... eg. It is certain that she will do well in her exam. ②It is＋名词词组(no wonder，an honour，a good thing，a pity，no surprise，common knowledge，a surprise， a fact，etc. )＋that... eg. It’s a pity that we can’t go. ③It is＋过去分词(said，reported，thought，expected，decided，announced，arranged，etc. )＋that... Eg. It has been suggested that much should be done to prevent the river from being polluted. ④It appears/seems that...|It happens that...|It occurred to me that...|It turned out that... Eg.It turned out that nobody remembered the address. 结果发现没人记得这地址。 ⑤It doesn’t matter that...|It makes no difference that... Eg.It doesn’t matter whether she will come or not. 2. 当that引导的主语从句出现在疑问句中时，要以it作形式主语，而把主语从句后置。 Does it matter much that they will not come tomorrow？ 3. 当主语从句出现在感叹句中时，要以it作形式主语，而把主语从句后置。 How strange it is that the children are so quiet！ 二、表语从句 表语从句放在连系动词之后，充当复合句中的表语。 一、引导表语从句的关联词的种类： 1. 可接表语从句的连系动词有be，look，seem，sound，appear等。 China is no longer what she used to be. The question remains whether they will be able to help us. At that time，it seemed as if I couldn’t think of the right word. 2. 从属连词whether，as，as if / though引导的表语从句。 He looked just as he had looked ten years before. 他看起来还与十年前一样。 It sounds as if someone is knocking at the door. 3. because，why引导的表语从句。 That’s because he didn’t understand me. （That’s because…强调原因） That’s why he got angry with me. （That’s why…强调结果） 4. 连接代词who，whom，whose，what，which，whoever，whatever，whichever 连接副词 where，when，how，why The problem is who we can get to replace her. The question is how he did it. That was what she did this morning . 5. 从属连词that The trouble is that I have lost his address. 三、宾语从句 ▲陈述句作宾语从句 　　陈述句包括肯定句和否定句。我们先复习陈述句作宾语从句时的三大方面的问题。 （一）连接词，陈述句作宾语从句时，用连接词that，通常that可以省略。 e.g.I think (that) English is difficult to learn. 但在有些动词后连接词that不能省略，在初中阶段我们学过的动词有learn, suggest, explain, agree, wonder, feel, mean。 e.g.However, he went on to explain that he was not too sure about the grammar. （二）语序，宾语从句要用陈述句的语序，而陈述句就是陈述句的语序，所以不必作任何改动。 （三）时态。在带有宾语从句的句子中，主句和从句的谓语动词在时态上是互有联系的，具体说来有三条。 1．当主句 ... ...
