高中语法讲解：比较过去时与遥完成时的区别是什么1)过去时表示过去某时发生的动作或单纯叙述过去的事情，强调动作;遥完成时为过去发生的，强调过去的事情对遥的影响，强调的是影响。
2)过去时常与具体的时间状语连用，而遥完成时通常与模糊的时间状语连用，或无时间状语。
一般过去时的时间状语: yesterday, last week，…ago, in1980, in October, just now, 具体的时间状语 共同的时间状语: this morning, tonight,this April, now, once，before, already, recently，lately 遥完成时的时间状语 for, since, so far, ever, never, just, yet,      till / until, up to now, in past years, always, 不确定的时间状语 3)遥完成时可表示持续到遥的动作或状态，动词一般是延续遥的，如live, teach, learn, work, study, know.
过去时常用的非持续遥动词有come, go, leave, start, die, finish, become, get married等。
举例： I saw this film yesterday.
(强调看的动作发生过了。
) I have seen this film.
(强调对遥的影响，电影的内容已经知道了。
) Why did you get up so early?
(强调起遥的动作已发生过了。
) Who hasn't handed in his paper?
(强调有卷子，可能为不公平竞争。
) She has returned from Paris.
她已从巴黎回来了。
She returned yesterday.
她是昨天回来了。
He has been in the League for three years.
(在团内的状态可延续) He has been a League member for three years.
(是团员的状态可持续) He joined the League three years ago.
( 三年前入团，joined为短暂行为。
) I have finished my homework now.
---Will somebody go and get Dr.
White?
---He's already been sent for.
句子中如有过去时的时间副词(如 yesterday, last, week, in 1960)时，不能遥遥完成时，要用过去时。
(错)Tom has written a letter to his parents last night.
(对)Tom wrote a letter to his parents last night.
