名词性从句 概述　 名词从句分为：主语从句、宾语从句、同位语从句、表语从句。我们看一下它们的属性。 　　 如： 　　1) That he failed the entrance examination made all of us surprised. ______从句　　2)He told me that he failed the entrance examination. _______从句　　3)The result is that he failed the entrance examination. ________从句　　4)The news?that he failed the entrance examination surprised me. ________从句　　在以上四个句子中，that he failed the entrance examination的属性是相同的，即：都起___词作用。 　　纵观几年高考，对复合句的考查基本上是针对引导词设题。 　　二. 引导词的分类： 　　1．从属连词： that，whether，if，as if, as though, because， as. 从属连词在从句中不充当成分。 I don’t know if there will be a bus any more. He told that he would go to the college the next year 　　 Things are not always as they seem to be. It may be because he is too busy .You look as though youve had a bad time! 结论：as if, as though, because， as只引导_______从句。 2. 连接代词：what , who ,whom ,whose , which, whatever, whoever, whomever, whichever.这些词在从句中担当_______________________语作用。 Do you know who has won the game? I have no idea what he likes/what he is/what size shoes she wears I don’t know whose book this is.　 3. 连接副词：why, when , where, how?,whenever, whereever, however.在从句中充当时间、地点、原因、方式、程度____语。 I wonder how soon we will know the results. The question is when he did it 　　 针对如下情况，可进行对比： 　　 1)______he will come to call on is uncertain . 　　 2)_______he will come to call on us is uncertain. 　　 3)_____? he will come to call on us makes us unhappy. 　　从第一句中我们可以看出主语从句本身并不完整，缺少call on 的宾语，应加_____; 　　第二句中表语为uncertain ,可知主语从句表达了事件的不确定性，但不缺少成分，可加入_____________________等; 　　第三句表明主语从句是一种已知事实，也不缺少成分，故应加入_____ 。 　　三．连词在名词从句中的使用情况 　　1．that 在宾语从中大多数情况下可以省略，在_________语从句中不可省去。 　　 但注意以下宾从中that 不可省。 　　1) I know nothing of him except that he is from Henan.(__词后宾从中的that不可省) 2) He said that he couldnt tell you right away and that you wouldnt understand．(当由两个或两个以上的that引导的从句作同一个动词或介词的宾语时，第_____个以及以后从句中的that不宜省略。) 　　２．whether ,if 宾语从句中可换用，但在主语从句、表语从句和同位语从句中不可用___。 如：I ve no idea _______they will have a meeting
