2、法要点剖析 一、名词性从句 主语从句、表语从句、宾语从句、同位语从句,在整个句子中所起的作用,相当于一个名词。因此,这四种从句通称为名词性从句。名词性从句成分的划分是根据句子在句中的位置划分的。任何一个句子一旦位于某个成分的位置上,它就成了相应的从句。试分析下列从句属于什么类型的名词性从句。1 Whether he will come or not is unknown.=It is unknown whether he will come or not.2 I dont know whether he will come or not.3 The question is whether he
3、 will come or not.4 The question whether he will come or not is not settled.引导名词性从句的连接词可分为三类:连接词:that,whether,if(不充当从句的任何成分)连接代词:what,whatever,who,whoever,whom,whose,which.(在从句中充当主语,宾语,表语,定语)连接副词:when,where,how,why(在从句中充当状语)1.主语从句 作句子主语的从句叫主语从句。主语从句通常由从属连词 that,whether,if 和连接代词 what,who,which,whatev
4、er,whoever 以及连接副词 how,when,where,why 等词引导。that 在句中无词义,只起连接作用,放在句首不能省略但当主语从句位于句尾时可以省略;连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用,在从句中充当从句的成分。主语从句中主句谓语用单数。例如:1That anyone becomes successful without the assistance of others is rare.=It is rare(that)anyone becomes successful without the assistance of others 2 Whethe
5、r it rains or shines makes no difference to proactive people.(不能用 if)3 It depends upon hard work more than luck whether(if)you can succeed in making your dream come true.4 Whoever wants to reach a distant goal must take many small steps.5 Whoever neglect learning in his youth loses the past and is d

7、ship is all predestined.爱情是酒,友谊是花,亲情似水。酒醉酒醒,花开花落,皆因一个“缘”字 有时为避免句子头重脚轻,常用形式主语 it 代替主语从句作形式主语放于句首,而把主语从句置于句末。主语从句后的谓语动词一般用单数形式。如例 1,2 常用句型如下:(1)It+be+名词+that 从句 (2)It+be+形容词+that 从句(3)It+be+动词的过去分词+that 从句 (4)It+不及物动词+that 从句 另注意在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时,谓语动词要用虚拟语气“(should)+do”,常用的句型有:It is necessa
