Ihavereadtwonovels.我已读过两本小说。（动作已完成）
Ihavebeenwritingletters.我一直都在写信。
Ihavewrittenthreeletters.我已经写完三封信了。

Ihavelivedheresince1990./Ihavebeenlivingheresince1990.
Theyhavestudiedtheproblemforquitesometime./Theyhavebeenstudyingtheproblemforquitesometime.
3、有些动词动词本身表示一种持续的状态，一般不用现在完成进行时，如be,know,love,remember,understand,see,like,last。

Theyhavenotseeneachotherforalongtime.
Thewarhaslastedforalongtime.
