宾语从句三件事，
时态语序连接词。
主从时态要一致，
陈述语序才合适。
一般问句做从句，
连接词 if 别忘记！
特殊问句作宾从，
特殊问词莫漏掉！
【说明】
宾语从句的组成必须抓住三个要点：时态、语序和连接词。首先主句和从句的时态必须保持一致，即主句时态为一般现在时，从句可根据需要用各种时态；如果主句为一般过去时，从句只能用过去时中的某种时态 ( 一般过去时、过去进行时、过去完成时、过去将来时等 ) 。
其次，不管什么类型的宾语从句它总是用陈述句语序，即：从句的连接词后是主→谓→宾……的语序 ( 连接词作主语时，后面直接跟谓语、宾主等 ) 。
再次，一般疑问句作宾语从句，除了牢记上述两点外还必须牢记在主从句之间加连接词“if” ( 或 whether) 。
最后，特殊疑问句作宾语从句，直接用特殊疑问词作引导词，后面的句子用陈述语序即可。
