现在完成进行时由“have (has)+been+现在分词”构成，表示现在以前一直在进行的动作。有些词，如work, study, live, teach等用现在完成进行时与用现在完成时意思差不多。例如：
I have worked here for three years.
I have been working here for three years.
但多数动词在这两种时态中表示不同意思。例如：
I have written a letter(已写完)
I have been writing a letter(还在写)
注意：表示短暂动作的动词，如finish, marry, get up, come go等不能用这种时态。
