现在完成时（Present perfect）过去发生并且已经完成的动作对现在造成影响或后果,过去某一时间开始并一直持续到现在并且有可能还会持续的动作或状态.（强调过去对现在的影响）
现在完成进行时,主语+助动词（have/has）+been+动词的现在分词+其他成分.表示动作从某一时间开始,一直持续到现在,或者刚刚终止,或者可能仍然要继续下去.（与since,for连用时,常常表示动作会进行下去）,如：
    I have been studying  English for 5 years.
  4.现在完成时比现在完成进行时更加常用,一般不使用have been being,常用have been/done
. 
  5.现在完成时,have done,其被动语态,have/has been done
     现在完成进行时,have/has been doing ,其被动语态,have/has been being done.

有这种用法,表示这种状态从过去一直持续到现在,可能还将继续持续下去

现在完成进行时的构成为：
I/ we/ you/ they have been doing sth.

have been in，
have been to，
have gone to
这三个短语都有“到某地去”的意思，但涵义和用法各不相同。
Have been in强调“过去曾去过”之意，表示经验；have been to的意思是“过去到过而现在已返回”，它强调“最近的经历”；have gone to表示“动作的完成”，强调人已离开说话的地方。
