has been+动词进行时 与 has+动词过去分词 有什么区别?

has been+动词进行时 与 has+动词过去分词 有什么区别? has been 与has+动词过去分词有什么区别 现在完成进行时的句型是 主语+助动词have/has+been+doing,若没有动词,则为例：Lana has been a nurse since 2009. 关于has been用法has been 是表示现在完成进行时,一般是have/has been+动词-ing.The door has been locked.这是格式怎么理解,我的意思是has been 后面应该是加动词+ing,为什么是加ed形式，就是这点不解。 has been 与 has gone 的区别? has seen与has been seen 句型转换 His grandfather died two years ago .His grandfather has ____ ____ for two years.有人说是填been dead 为什么has been 不是现在完成进行时吗 但是与题意不符啊 另外 公式是主语+have/has +延续性动词的过去 为什么现在完成进行时是have/has+been+动词进行时态 但是在“I have been为什么现在完成进行时是have/has+been+动词进行时态 但是在“I have been married for two years ”这句话里marry没加ing has been died 与has been dead的区别.. has been 现在完成进行时不是由“助动词have(has) + been+动词的现在分词”构成的吗 那having done是什么啊 has been to 与has gone to的区别 has been left与has left的区别 has left与 has been left的区别 has gone与has been该什么时候用 has been kept 与has kept有什么不同 英语翻译如题buy不是瞬间动词么？在完成时里面能说has bought 我只听过has keep.如果要把瞬间动词变成延续性动词的话，是不是应该加been,变成has been bought? Your help has been very valuable.看着象完成时`为什么没动词呢``
