        one day可指過(guò)去或?qū)?lái),即可用于過(guò)去時(shí)態(tài)或?qū)?lái)時(shí)態(tài)。one day既有一天的意思,又有某天的意思。one day也可用作狀語(yǔ),表示“有一天”。

        擴(kuò)展資料

          一般過(guò)去時(shí):

          1、概念:過(guò)去某個(gè)時(shí)間里發(fā)生的動(dòng)作或狀態(tài);過(guò)去習(xí)慣性、經(jīng)常性的動(dòng)作、行為。

          2、時(shí)間狀語(yǔ):ago,yesterday,the day before yesterday,last week,last(year,night,month…),just now,at the age of 5,one day,long long ago,once upon a time,etc.

          3、基本結(jié)構(gòu):be動(dòng)詞;行為動(dòng)詞的過(guò)去式

          4、否定形式:was/were+not;在行為動(dòng)詞前加didn't,同時(shí)還原行為動(dòng)詞。

          5、一般疑問(wèn)句:was或were放于句首;用助動(dòng)詞do的過(guò)去式did 提問(wèn),同時(shí)還原行為動(dòng)詞。

          6、例句:She often came to help us in those days.

          I didn't know you were so busy.

          7、用法:

          (1)一般過(guò)去時(shí)表示過(guò)去的`動(dòng)作或狀態(tài),一般過(guò)去時(shí)通常與表示過(guò)去的時(shí)間狀語(yǔ)連用。

          與一般過(guò)去時(shí)連用的時(shí)間狀語(yǔ)有:yesterday,last night(week,year,month,Sunday),then,at that time,at that moment,just now,a few days(weeks,months,years) ago等。例句:

          Lucy turned off all the lights before she went out.

          出門前露茜關(guān)了所有的燈。

          (2)一般過(guò)去時(shí)也可以與today,this week(month,year)等時(shí)間狀語(yǔ)連用,但這些時(shí)間狀語(yǔ)應(yīng)指過(guò)去。如:

          Did you see him today? 你今天見他了嗎?(today指今天已過(guò)去的某一時(shí)刻)

         。3)一般過(guò)去時(shí)還可以和for或since引導(dǎo)的時(shí)間狀語(yǔ)連用。如:

          I stayed there for two months. 我在那里呆了兩個(gè)月。

          Nothing happened since then. 打那以后什么事都沒有發(fā)生。
