Isawthisfilmyesterday.（只说明动作发生在过去。）

Ihaveseenthisfilm.（强调对现在的影响，电影的内容已经知道了。）ShehasreturnedfromParis.

（她已从巴黎回来了。）Shereturnedyesterday.（她是昨天回来的。）HehasbeenintheLeagueforthreeyears.(在团内的状态可延续)HejoinedtheLeaguethreeyearsago.

(三年前入团，joined为短暂行为。)

注意：句子中如有一般过去时的时间副词（如yesterday,lastweek,in1960）时，不能使用现在完成时，要用过去时。例如：（错）Tomhaswrittenalettertohisparentslastnight.（对）Tomwrotealettertohisparentslastnight.2026/8/1822eat-see-read-
