表示“过去时间”这种说法是不准确的。正确的说法应该是表示先于主句谓语动作时间。如果主句为一般现在时,那么现在完成时和一般过去时表示的动作都是先于主句谓语时间(现在)的,所以都有可能。需要根据语境判断应该用现在完成时还是一般过去时。

No one knows if this metal plate was Drake's or not.It depends on if my boss wants to do.这两个if从句都是占据了宾语的位置:动词的宾语和介词的宾语。因此if引导的是名词性从句。if是连词,不做句子成分,但有词义。引导状语从句时,意为“如果,或尽管”(条件或让步);引导名词性从句时,意为“是否”。引导宾语...
