要看什么样的从句,从句通常是一般过去式,这就是“时态的呼应”。但是如果宾语从句的内容是不受时间限制的客观真理,那么主句用了过去时,宾语从句要用一般现在时。比如确凿的历史。
但是事实上主句是一种过去时,从句应该为各种相应过去时态。
例如:
He wanted to know who hadn’t passed the exam.
He wanted to know when she would leave this building.
He wanted to know why she cried last night.
He wanted to know where she was going to study.
追问那如果从句是我认为的,喜欢的,比如like think呢
追答你可以参考一下例句,一般情况下,要看从句的语态,对应主句的时间点,如果是过去,就属于过去的过去要用过去完成时,如 he wanted to know who hadnt passed the exam.
