第一篇：13 - 一般过去时与现在完成时的转换

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 passed since + 一般过去时”的句型中。

第三篇：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.。?

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?seen?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）?

5）句子中如有过去时的时间副词（如yesterday,?last,?week,?in?1960）时，不能使用现在完成时，要用过去时。?

（错）Tom?has?written?a?letter?to?his?parents?last?night.?

（对）Tom?wrote?a?letter?to?his?parents?last?night.

He has just gone out.I have already finished my lunch.与一般过去时的区别。一般过去时表示事情发生在过去，不强调与现在的关系，与表示过去的时间状语连用。现在完成时强调与现在的关系、对现在的影响，不能与表示过去的时间状语连用。

现在完成进行时（have/has been doing）。动作从过去开始，一直延续到现在。How long have you been collecting shells? Have you been skating for five hours?

现在完成进行时与现在完成时的区别
