第二篇：比较一般过去时与现在完成时
比较一般过去时与现在完成时
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；现在完成时为过去发生的，强调过去的事情对现在的影响，强调的是影响。?
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：yesterday,?last?week，…ago,?in1980,?in?October,?just?now等，皆为具体的时间状语。?
现在完成时的时间状语：for,?since,?so?far,?ever,?never,?just,?yet,?till/until,?up?to?now,?in?past?years,?always等，皆不确定的时间状语。?
共同的时间状语：this?morning,?tonight,?this?April,?now,?already,?recently,?lately?等。?
3）现在完成时可表示持续到现在的动作或状态，动词一般是延续性的，如live,?teach,?learn,?work,?study,?know.。?guangzhou
4）一般过去时常用的非持续性动词有come,?go,?leave,?start,?die,?finish,?become,?get?married等
例如：?
I?saw?this?film?yesterday.?（强调看的动作发生过了）?
I?have?en?this?film.?（强调对现在的影响，电影的内容已经知道了）?
Why?did?you?get?up?so?early??（强调起床的动作已发生过了）?
Who?hasn't?handed?in?his?paper??（强调有卷子未交，疑为不公平竞争）?
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）?

一般过去时与现在完成时的转换
在现在完成时中，延续性动词能与表示一段时间的状语连用，瞬间动词却不能。但是，可用别的表达方式：
①瞬间动词用于“一段时间 + ago”的一般过去时的句型中；
②瞬间动词可改成与之相对应的延续性动词及短语，与一段时间连用；
③瞬间动词用于“It is + 一段时间 + since + 一般过去时”的句型中，表示“自从……以来有……时间”的意思，主句一般用it is来代替It has been;
④瞬间动词用于“Some time has pasd since + 一般过去时”的句型中。
