    過(guò)去進(jìn)行體是由

    助動(dòng)詞be的過(guò)去時(shí)形式(was,were)

    + -ing分詞(即動(dòng)詞的ing形式)構(gòu)成

    過(guò)去進(jìn)行體和現(xiàn)在進(jìn)行體的用法有不少相似之處

    只是時(shí)間向過(guò)去推移而已


    ⑴ 過(guò)去進(jìn)行體的肯定形式和否定形式



    而進(jìn)行時(shí)最重要的是

    動(dòng)詞的ing形式變化

    而這個(gè)變化是有規(guī)律的



    ⑵  過(guò)去進(jìn)行體的疑問(wèn)形式






    直接將be的過(guò)去時(shí)形式(was,were)放在首位




    ⑶ 過(guò)去進(jìn)行體的肯定回答和否定回答





    ⑷過(guò)去進(jìn)行體的用法
