discussed first.,（同位语从句）,The suggestion,that he had made,was not accepted.,（定语从句）,注意：同位语从句和定语从句的区别是：前者说明名词的内容，后者说明名词的性质特征；前者所用连词,that,不是从句的一个成分，后者所用关系代词,that,是从句中的一个成分。,以上是名词性从句例题解析，下面就运用名词性从句时要注意的几个方面作以归纳：,1.,语序,在名词性从句中，,从句一律使用陈述语序。,特别要注意由连接代词和连接副词引导的从句,(what,who,which,when,where,now,why,等,),不可因特殊疑问句的影响而用了疑问句语序。如：,(1)I wonder,who she is.,(2)The question is,when well,complete the works.,(3),Whether she is coming or not,doesnt matter too much.,2.,时态：,注意,从句谓语动词与主句谓语动词的时态一致关系。,在宾语从句中，当主句是一般现在时，宾语从句可以根据需要用各种时态。如：,Mary says that,Tom isnt lazy.,Tom is doing well in his lesson.,She will ask Tom some questions.,Tom may fall behind the others.,She missed us very much.,She was writing a letter.,She would visit the Great Wall.,She said that,如果主句谓语动词是一般过去时，则宾语从句须用过去的某种时态。如：,如果宾语从句表示的是客观真理，其谓语动词则仍用一般现在时。如：,(1)The teacher said,that light travels much faster than sound.,(2)The old man said,the sun rises in the east and sets in the west.,在主语从句，表语从句和同位语从句中，也要注意从句谓语动词与主句谓语动词的时态一致性。关键要,注意动作发生的先后关系,。如：,(1)Who,will,be sent abroad,has not been decided.,（,主句是现在完成时，从句是一般将来时）,(2)The earth of today,is,not what it,was,millions of years ago.,（,主句是一般现在时，从句是一般过去时,),在动词,think,believe,expect,suppose,guess,等后带,that,宾语从句时，若从句是否定句，常将否定词,not,转移到主句中。如：,3,、宾语从句的否定转移：,I dont think(that)it will be cold today.,We dont think you can do it,can you?,注意：这类句子后若带有附加疑问句，应采用肯定形式来反问，反问部分应于从句主语一致。,I dont believe she know it,does she?,1.My hometown is no longer_it,used to be.（）,练习题：,A.that,B.what,C.when,D.which,B,2.They wonder_ their son
