高考英语 语法突破四大篇 第四部分 专题2 名词性从句讲义-人教版高三全册英语学案

专题 2 名词性从句框架结构图 名词性从句(主语从句、宾语从句、表语从句、同位语从句)中的连接词名词性从句中的连接词有从属连词 that/whether/if 等，连接代词 what/who/which/whose/whatever/whoever/whomever/whichever 等 ， 连 接 副 词 where/when/why/how/wherever/whenever 等。1.that 的用法：(1)主语从句、表语从句、同位语从句中用 that 但不能省略。That they are good at English is known to us all.The problem is that we don’t have enough money.The report that there will be a severe storm in the northern area is false.(2)一般情况下，宾语从句中的引导词 that 可省略，但在以下几种情况中 that 一般不省略：①当 that 从句和主句谓语动词之间有插入语时；②有多个 that 引导的从句时，第一个 that可以省略，而其他的 that 常不可省略；③介词 except，but，besides，in 等后跟 that 引导的宾语从句时；④当 when，who，what，where，why，how 等引导的从句与 that 引导的从句作主句谓语动词的并列宾语时。He judged that，because he was a child，he did not understand wine.The reason lies in that she works harder than the others do.Everyone knew what happened and that she was worried.(3)that 和 what 的区别。that 引导名词性从句时，在主从句中不担当任何句子成分，也没有任何含义；而 what 引导名词性从句时，在主从句中都要充当一定的句子成分，what 可以分解成定语从句中的“先行词＋关系代词”，即常说的“先行词＋that/which/who”。It’s a shame that he has made such a mistake.I will do what I can (do) to help him.1(4)同位语从句与定语从句中 that 的区别。同位语从句中的连接词 that 只起连接作用，在从句中不担当任何句子成分；而定语从句中的关系代词 that 在句中作宾语或主语，与先行词有修饰关系。如果句子是同位语从句，就应用连接词 that 而不能用 which。同位语从句一般放在表具体含义的名词后解释说明名词的含义或内容，如以下名词：news，fact，suggestion，truth，plan，belief，doubt，possibility，idea 等，而定语从句只是对先行词的限定和修饰。They expressed the hope that they would come to visit China again.(...
