区分宾语从句、定于从句和状语从句宾语从句和状语从句，都叫做主从复合句。宾语从句主要是中考必考的，是初中阶段必掌握的从句，宾语从句主要是掌握三要素，所谓宾语从句，就是宾语在主从复合句当中充当宾语的一个句子，叫做宾语从句。主句的谓语动词是及物动词，后面如果是词或者是短语的话，是简单句，如果是句子的话，肯定是宾语从句。I know that he good at English.就是宾语从句，三要素，一要素是要注意连词，连词一共学了三类连词，一类连词是that口语当中可以省略，就像刚才说的那一句，I hear he is good at English.还有疑问代词、疑问副词，how where when，疑问代词、疑问副词。还有一类连词weather是否的意思，不是状语从句当中的如果，这一定要和如果区分开，这是是否。I don't know if he interested at English。宾语从句要注意if是连词。第二要素是语序，要用陈述举语序。比如说你家有几口人，我们都说How many people are there in you family?但是这是简单句，一旦说成宾语从句，你可以告诉我你家有几口人吗？Could you tell me how many people there are in you family ?
