      at that time用過(guò)去式的時(shí)態(tài)。
      at that time的例句:
      1、At that time my father was head of Paramount Studios.
      2、I was stupid at that time.
      3、I was cleaning my house at that time.

      擴(kuò)展資料

        英語(yǔ)時(shí)態(tài):

        1、一般現(xiàn)在時(shí):經(jīng)常、反復(fù)發(fā)生的動(dòng)作或行為及現(xiàn)在的某種狀況。

        時(shí)間狀語(yǔ):always, usually, often, sometimes, every week , once a week, on Sundays, etc.

        基本結(jié)構(gòu):be動(dòng)詞、行為動(dòng)詞

        否定形式:am/is/are+not、此時(shí)態(tài)的謂語(yǔ)動(dòng)詞若為行為動(dòng)詞,則在其前加don't,如主語(yǔ)為第三人稱單數(shù),則用doesn't,同時(shí)還原行為動(dòng)詞。

        2、一般過(guò)去時(shí):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。

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

        基本結(jié)構(gòu):be動(dòng)詞:行為動(dòng)詞

        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。

        3、現(xiàn)在進(jìn)行時(shí):表示現(xiàn)階段或說(shuō)話時(shí)正在進(jìn)行的動(dòng)作及行為。

        時(shí)間狀語(yǔ):now, at this time, these days, etc.

        基本結(jié)構(gòu):am/is/are+doing

        否定形式:am/is/are+not+doing.

        一般疑問(wèn)句:把be動(dòng)詞放于句首。
