have been 是现在完成进行时的标志,那为什么i have been to korea twice 是现在完成时 have been done 什么东西?have been doing是现在完成进行时的被动语态嘛? [现在进行完成时]一直和你在一起：have been with you 还是 have been being with you如题关于一个现在进行完成时的问题：“一直和你在一起”是have been with you 还是 have been being with you? have been doing和have been done哪个是现在完成进行时啊? 现在完成进行时的被动语态结构是have been +过去分词还是have been+doing例如：They have been collecting some stamps since2000Some stamps have been collected by them since 2000 be occupied with 、、嗯、现在完成时当然是说“have/has been occupied with”,那个、这里的“have/has”是不是表是完成呐、那个“been”又是什么意义啊?还有、现在完成进行时“have/has been doing”、那 现在完成被动进行时是否是：have been being done,请给例句并说明 I have been graduate 现在完成进行时吧?graduate是动词 现在完成被动进行时是否是：have been being done,请给例句并说明 现在完成进行时的主动和被动语态都是have been doing吗? 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. have been+adj 是属于现在完成时还是现在完成进行时呢?因为adj形容词是表示一个状态,是有延续的作用的,那是不是可以归纳为现在完成进行时呢? Nothing could have been more annoying.这里用的是现在完成进行式表示的是什么意思? 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 i have been getting scammed 是现在完成进行时 如果我想说现在完成时 可以用 i have been got scammed I have been looking forward to seeing you这是现在完成进行时的事态,为什么to后的see要加ing形式. I have been very busy the last few days 这句话算什么时态?have been doing是现在完成进行时 have been done 应该是完成时的被动语态 那我上面这句话算什么呢?have been 有什么用法也帮我补充下 现在完成进行时 例如 Have you been.后可加非延续性动词（不是V-ing形式的）吗?
