怎样分清楚过去式和现在式

怎样分清楚过去式和现在式
先来说一说一般现在时的概念吧:“经常.反复发生的动作或行为即现在的某种情况.”
但分析的时候还要注意时间状语:always.uaually.often.sometimes.every week(day.year.month...).once a week.on Sundays.
例句:It seldom snows here.
He is alwaysready to help others.
Action speaks louder than words.
在来说已说一般过去时的概念吧:“过去末各时间里发生的动作或状态;过去习惯性.经常性的动作,行为.”
但也要注意注意时间状语哦:ago.yesterday.the day before yesterday.last week(year.night.month...).in 1999.just now.at the ago of 5.one day.long long ago.once upon a time.
例句:She often came to help us in those days.
I didn't know you were so busy.
(...说了这么多你应该都记住了吧!...)

看 谓语动词的时态 来判断,did,动词ed形式都是过去式,现在时是 动词的原形或 单三形式,也可根据 句子里的 时态关键词判断
