1. Uses (cách dùng)

+) Diễn tả một sự việc, hành động đang xảy ra tại một thời điểm xác định trong quá khứ. Thời điểm đó được đo bằng:

       •  at + giờ/ phút    (at 6 a.m yesterday)

          Eg:  She was having dinner at 6 p.m yesterday.

       •  Một hành động quá khứ đơn xảy ra sau, đan xen.

           Eg:  When he phoned her, she was having a bath.

              hành động xảy ra sau, đan xen

+) Diễn tả hai hay nhiều sự việc đang xảy ra đồng thời tại một thời điểm xác định trong quá khứ (thường đi với từ “while”)

     Eg:  At 7 a.m yesterday , while I was going to school , my mother was doing the housework, my father was working in the garden.

+) Diễn tả một sự việc bất thường ở quá khứ

2. Forms (cấu trúc)

(+)  S + was/ were + V-ing…

(-)  S + wasn’t/ weren’t + V-ing…

(?)  Was/ were + S + V-ing…

(?)  Wh_ + was/ were + S + V-ing…

   Eg:  (+)  I was going to school at 11.30 yesterday.

-) tận cùng là “y” +ing :         study => studying

                                                 play   => playing

-) tận cùng là “e” câm thì bỏ “e” thêm “ing”

            Eg:      write  => writing                                        make => making

                        have  => having                                          take => taking

                        drive=> driving

Trừ:    age => ageing

            dye => dyeing

            singe => singeing

-) nếu từ có 1 âm tiết hoặc 2 âm tiết nhưng trọng âm rơi vào âm tiết thứ 2 mà trước phụ âm cuối chỉ có 1 nguyên âm thì gấp đôi phụ âm cuối rồi thêm “ing”

            sit => sitting                                               control => controlling

            run => running                                           occur => occurring

            swim => swimming                                    admit => admitting

Đặc biệt:    travel => traveling/ travelling

-) tận cùng là “ie” => y +ing

            die => dying

            lie => lying

-) tận cùng là "w" => không gấp đôi

            Eg : draw => drawing

4. Một số động từ không thường dùng ở các thì tiếp diễn
