that, whether / if引导的宾语从句在复合句中，由一个句子充当宾语，这个句子叫作宾语从句。
我们需要从三方面来学习由that, whether / if引导的宾语从句。
一、关联词1.陈述句作宾语时，宾语从句用that引导。
that只起连接作用，没有实际意义，在从句中不充当任何成分，因此常省略。
如：He can visit Beijing one day. My brother hopes. (合并为含有宾语从句的复合句)My brother hopes (that) he can visit Beijing one day.2.一般疑问句作宾语时，宾语从句用whether或if引导。
whether和if意为“是否”，在从句中不充当任何成分，但不可省略。
如：Is Tom's sister an English teacher? May wants to know.(合并为含有宾语从句的复合句)May wants to know whether / if Tom's sister is an English teacher.二、语序that, whether / if引导的宾语从句要用陈述句语序。
如：Will she go to Beijing tomorrow? I don't know.(合并为含有宾语从句的复合句)I don't know whether / if she will go to Beijing tomorrow.三、时态1.如果主句是一般现在时，that, whether / if引导的宾语从句可根据需要使用适当的时态；如果主句是一般过去时，that, whether / if引导的宾语从句用相应的过去时态(一般现在时→一般过去时，现在进行时→过去进行时，一般将来时→过去将来时，现在完成时→过去完成时，一般过去时→过去完成时)。
如：Andy knows (that) his wife bought a nice dress yesterday.I want to know whether / if my father will go to London next week.Jack believed (that) Mary made up the story.Mary wondered whether / if Jenny was watching a movie at 8:00 p.m. yesterday.2. that, whether / if引导的宾语从句表示客观事实或真理时，其时态不受主句限制，用一般现在时。
