过去完成时过去分词要用延续性动词吗

过去完成时过去分词要用延续性动词吗

时态和延续性还是短暂性无关。关键是短暂性动词作成完成时态时，不能和表示一段时间的状语连用。

提问不规范 回答也不规范 那能说现在完成时加过去分词 那是神马

现在完成时必须有过去分词 它的构成 主语+have/has+过去分词

完成时态中 如含有一段时间的for短语和since短语 时 动词必须是延续性动词 如

he has died for two days 错 应是 he has been dead for two days.

he has bought the car for two years 错 应是 he has had the car for two years.

he has come here for two days 错 应是 he has been here for two days.

因为过去完成时既可表示过去某个时间或动作之前所发生的事情(常用时间状语有already, before, ever, just, never, still, yet)，也可表示过去某个时间或动作之前所发生的动作一直持续到过去某个时间(常接时间状语：since +时间点, for + 时间段)。 所以在上文的第一种情况用不延续性的 如When I got to the station, the train had left. 当我到达车站时，火车已经开走了。 第二种情况用延续性 He said that he had lived there since he was ten. 他说他十岁起就住在那儿了。
