—句中—句末一般过去时与现在完成时之比较1）一般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，和现在不发生关系。而现在完成时表示过去发生的某一动作对现在造成的影响或结果，强调的是现在的情况。
2）一般过去时常与具体的时间状语连用，而现在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有：yesterday, last week，…ago, in1980, in October, just now,等具体的时间状语。
◎ 共同的时间状语有：this morning, tonight, this summer, before, already,等。　
◎ 现在完成时的时间状语有：for, since, ever, never, just, already, yet等不确定的时间状语。
请大家认真分析比较下列各例句： I saw this film yesterday. （只说明动作发生在过去。）
I have seen this film. （强调对现在的影响，电影的内容已经知道了。）　
She has returned from Paris.　（她已从巴黎回来了。）
She returned yesterday. （她是昨天回来的。）
He has been in the League for three years. (在团内的状态可延续)
He joined the League three years ago.　( 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, last week, in 1960）时，不能使用现在完成时，要用过去时。例如：
（错）Tom has written a letter to his parents last night.
（对）Tom wrote a letter to his parents last night. eat- see-
