解析：根据所提供的情景“It was really very kind of you to give me a lift home.”可判断出动作发生在过去,而“路过对方的家”表示过去正在发生的事,所以要用过去进行时。一般将来时表示将要发生的动作或存在的状态。过去完成时表示一个动作或状态在过去某一时间或动作之前已经完成或结束,也可能是早已完成或结束,即“过去的过去”;也可以指过去的动作延续到过去的某个时刻。现在完成时表示动作发生在过去某个不确定的时间,但对现在留下了某种影响和结果。常被just，already，yet 等副词修饰或表示从过去某一时刻开始一直持续到现在的动作或状态。这个动作可能刚停止,可能仍然在进行。常带有for和since等表示一段时间的状语。
